Brain Changes Found in Patients with Long-Term Lyme Disease

By Pat Anson, PNN Editor

Researchers at Johns Hopkins University have documented changes in the brains of patients with post-treatment Lyme disease that may explain symptoms such as brain fog, memory loss and other cognitive issues. The finding could also have implications for patients with long covid, fibromyalgia, multiple sclerosis, chronic fatigue and other health conditions who have cognitive problems.    

Lyme disease is a bacterial illness spread by ticks that causes a rash, flu-like aches and fever, joint pain and fatigue. Most patients fully recover when treated early with antibiotics, but up to 20% of those with post-treatment Lyme disease (PTLD) have long-term symptoms, including depression, insomnia and cognitive difficulties. There is usually no clinical or laboratory evidence to explain their ongoing issues.

“Objective biologic measures of post-treatment Lyme symptoms typically can’t be identified using regular MRIs, CT scans, or blood tests,” says John Aucott, MD., director of the Johns Hopkins Lyme Disease Clinical Research Center.

Aucott and his colleagues recruited 12 PTLD patients and 18 people without a history of Lyme to undergo functional MRI (fMRI) scans while performing a short-term memory task. The scans allow investigators to track blood flow and other changes in the brain in real time.

Their findings, published in the journal PLOS ONE, suggest that cognitive difficulties in PTLD patients are linked to functional and structural changes in the “white matter” of the brain, which is crucial for processing and relaying information. The imaging tests revealed unusual activity in the frontal lobe, an area of the brain responsible for memory recall and concentration. Patients with post-treatment Lyme needed longer periods of time to complete the memory task.

“We saw certain areas in the frontal lobe under-activating and others that were over-activating, which was somewhat expected,” said lead author Cherie Marvel, PhD, an associate professor of neurology at Johns Hopkins.

“However, we didn’t see this same white matter activity in the group without post-treatment Lyme.”

To confirm their finding, researchers used another form of imaging called diffusion tensor imaging (DTI) on all 12 patients with Lyme and 12 of the non-Lyme participants. DTI detects the direction of water movement within brain tissue. Water was diffusing, or leaking, in the the same white matter regions identified in the fMRI.

Researchers believe the increased activity they saw in white matter may reflect an immune system response in the PTLD patients, which may also explain cognitive issues in patients with other chronic health conditions.

PLOS ONE

“Results reported here may have implications for other diseases in which white matter pathology has been demonstrated (e.g., multiple sclerosis) or in illnesses in which cognitive complaints follow disease onset,” researchers said. “The use of multimodal neuroimaging methods, like the ones used in the current study, may be a viable approach for obtaining information on brain function and structure to identify biomarkers of disease burden.”

Researchers say larger studies with more patients will be needed to confirm their findings, as well as long-term tracking of brain changes from the initial Lyme infection through development of PTLD.

Nearly 500,000 people are believed to get Lyme disease each year in the United States. Diagnoses of Lyme have soared over the past 15 years, according to a recent analysis of insurance claims that found Lyme cases rose 357% in rural areas and 65% in urban areas. The highest rates of Lyme were in New Jersey, Vermont, Maine, Rhode Island and Connecticut.

Experimental Vaccines Target Epstein-Barr Virus

By Liz Szabo, Kaiser Health News

Maybe you’ve never heard of the Epstein-Barr virus. But it knows all about you.

Chances are, it’s living inside you right now. About 95% of American adults are infected sometime in their lives. And once infected, the virus stays with you.

Most viruses, such as influenza, just come and go. A healthy immune system attacks them, kills them, and prevents them from sickening you again. Epstein-Barr and its cousins, including the viruses that cause chickenpox and herpes, can hibernate inside your cells for decades.

This viral family has “evolved with us for millions of years,” said Blossom Damania, a virologist at the University of North Carolina-Chapel Hill. “They know all your body’s secrets.”

Although childhood Epstein-Barr infections are typically mild, exposure in teens and young adults can lead to infectious mononucleosis, a weeks-long illness that sickens 125,000 Americans a year, causing sore throats, swollen glands, and extreme fatigue. And while Epstein-Barr spends most of its time sleeping, it can reawaken during times of stress or when the immune system is off its game. Those reactivations are linked to a long list of serious health conditions, including several types of cancer and autoimmune diseases.

Scientists have spent years trying to develop vaccines against Epstein-Barr, or EBV. But recently several leaps in medical research have provided more urgency to the quest — and more hope for success. In just the past year, two experimental vaccine efforts have made it to human clinical trials.

What’s changed?

First, the Epstein-Barr virus has been shown to present an even greater threat. New research firmly links it to multiple sclerosis, or MS, a potentially disabling chronic disease that afflicts more than 900,000 Americans and 2.8 million people worldwide.

The journal Science in January published results from a landmark 20-year study of 10 million military personnel that offers the strongest evidence yet that Epstein-Barr can trigger MS. The new study found that people infected with Epstein-Barr are 32 times as likely as people not infected to develop MS.

And shedding new light on the mechanisms that could explain that correlation, a separate group of scientists published a study in Nature describing how the virus can cause an autoimmune reaction that leads to MS.

The disease, which usually strikes between ages 20 and 40, disrupts communication between the brain and other parts of the body and is often marked by recurring episodes of extreme fatigue, blurred vision, muscle weakness, and difficulty with balance and coordination. At its worst, MS can lead to impaired speech and paralysis.

“Now that we know that Epstein-Barr is very tightly linked to MS, we could save a lot of lives if we develop the vaccine now.”

— Blossom Damania, Virologist

Amplifying that newfound urgency, several new studies suggest that reactivation of the Epstein-Barr virus also is involved with some cases of long covid, a little-understood condition in which patients experience lingering symptoms that often resemble mononucleosis.

And just as crucial to the momentum: Advances in vaccine science spurred by the pandemic, including the mRNA technology used in some covid vaccines, could accelerate development of other vaccines, including ones against Epstein-Barr, said Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine. Hotez co-created a low-cost, patent-free covid vaccine called Corbevax.

Some researchers question the need for a vaccine that targets a disease like MS that, while debilitating, remains relatively rare.

Eliminating Epstein-Barr would require vaccinating all healthy children even though their risk of developing cancer or multiple sclerosis is small, said Dr. Ralph Horwitz, a professor at the Lewis Katz School of Medicine at Temple University.

Before exposing children to the potential risks of a new vaccine, he said, scientists need to answer basic questions about MS. For example, why does a virus that affects nearly everyone cause disease in a small fraction? And what roles do stress and other environmental conditions play in that equation?

The answer appears to be that Epstein-Barr is “necessary but not sufficient” to cause disease, said immunologist Bruce Bebo, executive vice president for research at the National MS Society, adding that the virus “may be the first in a string of dominoes.”

‘We Could Save a Lot of Lives’

Hotez said researchers could continue to probe the mysteries surrounding Epstein-Barr and MS even as the vaccine efforts proceed. Further study is required to understand which populations might benefit most from a vaccine, and once more is known, Hotez said, such a vaccine possibly could be used in patients found to be at highest risk, such as organ transplant recipients, rather than administered universally to all young people.

“Now that we know that Epstein-Barr is very tightly linked to MS, we could save a lot of lives if we develop the vaccine now,” Damania said, “rather than wait 10 years” until every question is answered.

Moderna and the National Institute of Allergy and Infectious Diseases launched separate clinical trials of Epstein-Barr vaccines over the past year. Epstein-Barr vaccines also are in early stages of testing at Opko Health, a Miami-based biotech company; Seattle’s Fred Hutchinson Cancer Center; and California’s City of Hope National Medical Center.

Scientists have sought to develop vaccines against Epstein-Barr for decades only to be thwarted by the complexities of the virus. Epstein-Barr “is a master of evading the immune system,” said Dr. Jessica Durkee-Shock, a clinical immunologist and principal investigator for NIAID’s trial.

Both MS and the cancers linked to Epstein-Barr develop many years after people are infected. So a trial designed to learn whether a vaccine can prevent these diseases would take decades and a lot of money.

Moderna researchers initially are focusing on a goal more easily measured: the prevention of mononucleosis, which doubles the risk of multiple sclerosis. Mono develops only a month or so after people are infected with Epstein-Barr, so scientists won’t have to wait as long for results.

Mono can be incredibly disruptive on its own, keeping students out of class and military recruits out of training for weeks. In about 10% of cases, the crippling fatigue lasts six months or more. In 1% of cases, patients develop complications, including hepatitis and neurological problems.

For now, the clinical trials for Epstein-Barr immunizations are enrolling only adults. “In the future, the perfect vaccine would be given to a small child,” Durkee-Shock said. “And it would protect them their whole life, and prevent them from getting mono or any other complication from the Epstein-Barr virus.”

The NIAID vaccine, being tested for safety in 40 volunteers, is built around ferritin, an iron-storage protein that can be manipulated to display a key viral protein to the immune system. Like a cartoon Transformer, the ferritin nanoparticle self-assembles into what looks like a “little iron soccer ball,” Durkee-Shock said. “This approach, in which many copies of the EBV protein are displayed on a single particle, has proved successful for other vaccines, including the HPV and hepatitis B vaccine.”

Moderna’s experimental vaccine, being tested in about 270 people, works more like the company’s covid shot. Both deliver snippets of a virus’s genetic information in molecules called mRNA inside a lipid nanoparticle, or tiny bubble of fat. Moderna, which has dozens of mRNA vaccines in development, hopes to learn from each and apply those lessons to Epstein-Barr, said Sumana Chandramouli, senior director and research program leader for infectious diseases at Moderna.

“What the covid vaccine has shown us is that the mRNA technology is well tolerated, very safe, and highly efficacious,” Chandramouli said.

But mRNA vaccines have limitations.

Although they have saved millions of lives during the covid pandemic, the antibody levels generated in response to the mRNA vaccines wane after a few months. It’s possible this rapid loss of antibodies is related specifically to the coronavirus and its rapidly evolving new strains, Hotez said. But if waning immunity is inherent in the mRNA technology, that could seriously limit future vaccines.

Designing vaccines against Epstein-Barr is also more complicated than for covid. The Epstein-Barr virus and other herpesviruses are comparatively huge, four to five times as large as SARS-CoV-2, the coronavirus that causes covid. And while the coronavirus uses just one protein to infect human cells, the Epstein-Barr virus uses many, four of which are included in the Moderna vaccine.

Earlier experimental Epstein-Barr vaccines targeting one viral protein lowered the rate of infectious mononucleosis but failed to prevent viral infection. Targeting multiple viral proteins may be more effective at preventing infection, said Damania, the UNC virologist.

“If you close one door, the other door is still open,” Damania said. “You have to block infection in all cell types to have a successful vaccine that prevents future infections.”

Is Another Covid Spike Coming? 6 Tips to Help You Stay Safe

By Celine Gounder, Kaiser Health News

The emergence last year of the highly transmissible omicron variant of the covid-19 virus caught many people by surprise, and led to a surge in cases that overwhelmed hospitals and drove up fatalities. Now we’re learning that omicron is mutating further to better evade the immune system.

Omicron-specific vaccines were authorized by the FDA in August and are recommended by U.S. health officials for anyone 5 or older. Yet only half of adults in the United States have heard much about these booster shots, according to a recent Kaiser Family Foundation poll, and only a third say they’ve gotten one or plan to get one as soon as possible. In 2020 and 2021, covid cases spiked in the U.S. between November and February.

Although we don’t know for sure that we’ll see another surge this winter, here’s what you should know about covid and the updated boosters to prepare.

1. Do I need a covid booster shot this fall?

If you’ve completed a primary vaccination series and are 50 or older, or if your immune system is compromised, get a covid booster shot as soon as possible. Forty percent of deaths are occurring among people 85 and older and almost 90% among people 65 and over. Although people of all ages are being hospitalized from covid, those hospitalizations are also skewing older.

Unvaccinated people, while in the minority in the U.S., are still at the highest risk of dying from covid. It’s not too late to get vaccinated ahead of this winter season. The United Kingdom, whose covid waves have presaged those in the United States by about a month, is beginning to see another increase in cases.

If you’ve already received three or more covid shots, you’re 12 to 49 years old, and you’re not immunocompromised, your risk of hospitalization and death from the disease is significantly reduced and additional boosters are not likely to add much protection.

However, getting a booster shot provides a “honeymoon” period for a couple of months after vaccination, during which you’re less likely to get infected and thus less likely to transmit the virus to others. If you’ll be seeing older, immunocompromised, or otherwise vulnerable family and friends over the winter holidays, you might want to get a booster two to four weeks in advance to better shield them against covid.

You may have other reasons for wanting to avoid infection, like not wanting to have to stay home from work because you or your child is sick with covid. Even if you aren’t hospitalized from covid, it can be costly to lose wages or arrange for backup child care.

One major caveat to these recommendations: You should wait four to six months after your last covid infection or vaccination before getting another shot. A dose administered too soon will be less effective because antibodies from the previous infection or vaccination will still be circulating in your blood and will prevent your immune cells from seeing and responding to vaccination.

2. Do kids need to be vaccinated even if they’ve had covid?

Although children are at lower risk for severe covid than are adults, the stakes for kids are higher than many diseases already recognized as dangerous. Their risk shouldn’t be measured against the risk that covid poses to other age groups but against the risk they face from other preventable diseases.

In the first two years of the pandemic, covid was the fourth- or fifth-leading cause of death in every five-year age bracket from birth to 19, killing almost 1,500 children and teenagers. Other vaccine-preventable diseases like chickenpox, rubella, and rotavirus killed an average of about 20-50 children and teens a year before vaccines became available. By that measure, vaccinating kids against covid is a slam-dunk.

Children who have had covid also benefit from vaccination. The vaccine reduces their risk of hospitalization and missing days of school, when parents might need to stay home with them.

But it’s precisely because the stakes are higher for kids that many parents are anxious about getting their children vaccinated. As recently as July, just after the FDA authorized covid vaccines for children as young as 6 months, a KFF poll found that over half of parents of children under age 5 said they thought vaccines posed a greater risk to the health of their child than getting the disease. And in the most recent poll, half said they had no plans to get their children vaccinated. Covid vaccination rates range from 61% among children ages 12 to 17 to 2% among kids younger than 2.

Similar to influenza, covid is most deadly for the very youngest and oldest. At especially high risk are infants. They’re unlikely to have immunity from infection, and a small share have been vaccinated. Unless their mothers were vaccinated during pregnancy or got covid during pregnancy — the latter of which poses a high risk of death for the mother and of preterm birth for the baby — infants are probably not getting protective antibodies against covid through breast milk. And because infants have small airways and weaker coughs, they’re more likely to have trouble breathing with any respiratory infection, even one less deadly than covid.

3. Will I need a covid shot every year?

It depends on the targets set by public health officials whether covid becomes a seasonal virus like the flu, and how much the virus continues to mutate and evade humanity’s immune defenses.

If the goal of vaccination is to prevent severe disease, hospitalization, and death, then many people will be well protected after their primary vaccination series and may not need additional shots. Public health officials might strongly recommend boosters for older and immunocompromised people while leaving the choice of whether to get boosted to those with lower risk. If the goal of vaccination is to prevent infection and transmission, then repeat boosters will be needed after completing the primary vaccination series and as often as a couple of times a year.

Influenza is a seasonal virus causing infections and disease generally in the winter, but scientists don’t know whether covid will settle into a similar, predictable pattern. In the first three years of the pandemic, the United States has experienced waves of infection in summer. But if the covid virus were to become a wintertime virus, public health officials might recommend yearly boosters. The Centers for Disease Control and Prevention recommends that people 6 months and older get a flu shot every year with very rare exceptions. However, as with the flu, public health officials might still place a special emphasis on vaccinating high-risk people against covid.

And the more the virus mutates, the more often public health officials may recommend boosting to overcome a new variant’s immune evasion. Unfortunately, this year’s updated omicron booster doesn’t appear to provide significantly better protection than the original boosters. Scientists are working on variant-proof vaccines that could retain their potency in the face of new variants.

4. Are more covid variants on the way?

The omicron variant has burst into an alphabet soup of subvariants. The BA.5 variant that surfaced earlier this year remains the dominant variant in the U.S., but the BA.4.6 omicron subvariant may be poised to become dominant in the United States. It now accounts for 14% of cases and is rising. The BA.4.6 omicron subvariant is better than BA.5 at dodging people’s immune defenses from both prior infection and vaccination.

In other parts of the world, BA.4.6 has been overtaken by BA.2.75 and BF.7 (a descendant of BA.5), which respectively account for fewer than 2% and 5% of covid cases in the U.S. The BA.2.75.2 omicron subvariant drove a wave of infections in South Asia in July and August. Although the U.S. hasn’t yet seen much in the way of another variant descended from BA.5 — BQ.1.1 — it is rising quickly in other countries like the U.K., Belgium, and Denmark. The BA.2.75.2 and BQ.1.1 variants may be the most immune-evasive omicron subvariants to date.

BA.4.6, BA.2.75.2, and BQ.1.1 all evade Evusheld, the monoclonal antibody used to prevent covid in immunocompromised people who don’t respond as well to vaccination. Although another medication, bebtelovimab, remains active in treating covid from BA.4.6 and BA.2.75.2, it’s ineffective against BQ.1.1. Many scientists are worried that Evusheld will become useless by November or December. This is concerning because the pipeline for new antiviral pills and monoclonal antibodies to treat covid is running dry without a guaranteed purchaser to ensure a market. In the past, the federal government guaranteed it would buy vaccines in bulk, but funding for that program has not been extended by Congress.

Other omicron subvariants on the horizon include BJ.1, BA.2.3.20, BN.1, and XBB, all descendants of BA.2.

It’s hard to predict whether an omicron subvariant or yet another variant will come to dominate this winter and whether hospitalizations and deaths will again surge in the U.S. Vaccination rates and experience with prior infections vary around the world and even within the United States, which means that the different versions of omicron are duking it out on different playing fields.

While this might all sound grim, it’s important to remember that covid booster shots can help overcome immune evasion by the predominant omicron subvariants.

5. What about long covid?

Getting vaccinated does reduce the risk of getting long covid, but it’s unclear by how much. Researchers don’t know if the only way to prevent long covid is to prevent infection.

Although vaccines may curb the risk of infection, few vaccines prevent all or almost all infections. Additional measures — such as improving indoor air quality and donning masks — would be needed to reduce the risk of infection. It’s also not yet known whether prompt treatment with currently available monoclonal antibodies and antiviral drugs like Paxlovid reduces the risk of developing long covid.

6. Do I need a flu shot, too?

The CDC recommends that anyone 6 months of age or older get an annual flu shot. The ideal timing is late October or early November, before the winter holidays and before influenza typically starts spreading in the U.S. Like covid shots, flu shots provide only a couple of months of immunity against infection and transmission, but an early flu shot is better than no flu shot. Influenza is already circulating in some parts of the United States.

It’s especially important for people 65 or older, pregnant women, people with chronic medical conditions, and children under 5 to get their yearly flu shots because they’re at highest risk of hospitalization and death. Although younger people might be at lower risk for severe flu, they can act as vectors for transmission of influenza to higher-risk people in the community.

High-dose flu vaccines and “adjuvanted” flu vaccines are recommended for people 65 and older. Adjuvants strengthen the immune response to a vaccine. It is safe to get vaccinated for covid and the flu at the same time, but you might experience more side effects like fevers, headache, or body aches.

The ‘Parallel Pandemic’ of Long Covid

By Liz Szabo, Kaiser Health News

The latest covid-19 surge, caused by a shifting mix of quickly evolving omicron subvariants, appears to be waning, with cases and hospitalizations beginning to fall. Like past covid waves, this one will leave a lingering imprint in the form of long covid, an ill-defined catchall term for a set of symptoms that can include debilitating fatigue, difficulty breathing, chest pain, and brain fog.

Although omicron infections are proving milder overall than those caused by last summer’s delta variant, omicron has also proved capable of triggering long-term symptoms and organ damage. But whether omicron causes long covid symptoms as often — and as severe — as previous variants is a matter of heated study.

Michael Osterholm, director of the University of Minnesota’s Center for Infectious Disease Research and Policy, is among the researchers who say the far greater number of omicron infections compared with earlier variants signals the need to prepare for a significant boost in people with long covid.

The U.S. has recorded nearly 38 million covid infections so far this year, as omicron has blanketed the nation. That’s about 40% of all infections reported since the start of the pandemic, according to the Johns Hopkins University Coronavirus Research Center.

Long covid “is a parallel pandemic that most people aren’t even thinking about,” said Akiko Iwasaki, a professor of immunobiology at Yale University. “I suspect there will be millions of people who acquire long covid after omicron infection.”

Scientists have just begun to compare variants head-to-head, with varying results. While one recent study in The Lancet suggests that omicron is less likely to cause long covid, another found the same rate of neurological problems after omicron and delta infections.

Estimates of the proportion of patients affected by long covid also vary, from 4% to 5% in triple-vaccinated adults to as many as 50% among the unvaccinated, based on differences in the populations studied.

One reason for that broad range is that long covid has been defined in widely varying ways in different studies, ranging from self-reported fogginess for a few months after infection to a dangerously impaired inability to regulate pulse and blood pressure that may last years. Even at the low end of those estimates, the sheer number of omicron infections this year would swell long-covid caseloads.

“That’s exactly what we did find in the UK,” said Claire Steves, a professor of aging and health at King’s College in London and author of the Lancet study, which found patients have been 24% to 50% less likely to develop long covid during the omicron wave than during the delta wave.

“Even though the risk of long covid is lower, because so many people have caught omicron, the absolute numbers with long covid went up,” Steves said.

Reinfections Raise Risk

A recent study analyzing a patient database from the Veterans Health Administration found that reinfections dramatically increased the risk of serious health issues, even in people with mild symptoms. The study of more than 5.4 million VA patients, including more than 560,000 women, found that people reinfected with covid were twice as likely to die or have a heart attack as people infected only once. And they were far more likely to experience health problems of all kinds as of six months later, including trouble with their lungs, kidneys, and digestive system.

“We’re not saying a second infection is going to feel worse; we’re saying it adds to your risk,” said Dr. Ziyad Al-Aly, chief of research and education service at the Veterans Affairs St. Louis Health Care System.

Researchers say the study, published online but not yet peer-reviewed, should be interpreted with caution. Some noted that VA patients have unique characteristics, and tend to be older men with high rates of chronic conditions that increase the risks for long covid. They warned that the study’s findings cannot be extrapolated to the general population, which is younger and healthier overall.

“We need to validate these findings with other studies,” said Dr. Harlan Krumholz, director of the Yale New Haven Hospital Center for Outcomes Research and Evaluation. Still, he added, the VA study has some “disturbing implications.”

With an estimated 82% of Americans having been infected at least once with the coronavirus as of mid-July, most new cases now are reinfections, said Justin Lessler, a professor of epidemiology at the University of North Carolina Gillings School of Global Public Health.

‘Breathing Through a Straw’

Of course, people’s risk of reinfection depends not just on their immune system, but also on the precautions they’re taking, such as masking, getting booster shots, and avoiding crowds.

New Jersey salon owner Tee Hundley, 43, has had covid three times, twice before vaccines were widely available and again this summer, after she was fully vaccinated. She is still suffering the consequences.

After her second infection, she returned to work as a cosmetologist at her Jersey City salon but struggled with illness and shortness of breath for the next eight months, often feeling like she was “breathing through a straw.”

She was exhausted, and sometimes slow to find her words. While waxing a client’s eyebrows, “I would literally forget which eyebrow I was waxing,” Hundley said. “My brain was so slow.”

When she got a breakthrough infection in July, her symptoms were short-lived and milder: cough, runny nose, and fatigue. But the tightness in her chest remains.

“I feel like that’s something that will always be left over,” said Hundley, who warns friends with covid not to overexert. “You may not feel terrible, but inside of your body there is a war going on.”

Although each omicron subvariant has different mutations, they’re similar enough that people infected with one, such as BA.2, have relatively good protection against newer versions of omicron, such as BA.5. People sickened by earlier variants are far more vulnerable to BA.5.

Several studies have found that vaccination reduces the risk of long covid. But the measure of that protection varies by study, from as little as a 15% reduction in risk to a more than 50% decrease. A study published in July found the risk of long covid dropped with each dose people received.

For now, the only surefire way to prevent long covid is to avoid getting sick. That’s no easy task as the virus mutates and Americans have largely stopped masking in public places. Current vaccines are great at preventing severe illness but do not prevent the virus from jumping from one person to the next.

Scientists are working on next-generation vaccines — “variant-proof” shots that would work on any version of the virus, as well as nasal sprays that might actually prevent spread. If they succeed, that could dramatically curb new cases of long covid.

“We need vaccines that reduce transmission,” Al-Aly said. “We need them yesterday.”

Why I Still Take Precautions Against Covid

By Victoria Reed, PNN Columnist

We are three years into the Covid-19 pandemic, and while life has still not returned to normal, it’s understandable for people to be tired of hearing about the virus and less concerned about catching it. Scientists know more about covid and have developed tools to treat and even prevent the most serious outcomes.

But many of us who are suffering from chronic illness or chronic pain are still wearing masks, practicing social distancing and taking other precautions.

As I go out and about in my daily life, I’ve noticed that mask use is somewhat minimal. People don’t seem to be as concerned about the virus and its variants, even as cases are skyrocketing again. I’m one of the few who still wears a mask in crowded indoor places, airplanes and restaurants.

Fortunately, I have not yet been infected with covid. I attribute that to always being cautious in public (sometimes even outside) and when around family members who I know aren’t taking precautions. Being vaccinated and boosted is another layer of protection I believe has helped me.

The choice to be vaccinated is a personal one and should not be looked at as a political issue or be a source of ridicule. The same goes for mask use. Sometimes people look at me funny because I still wear a mask, but I am “allowed” to do that, just as others are equally allowed to stop wearing theirs.

I don’t judge people who choose not to wear a mask, and conversely, I shouldn’t be judged for wearing one.

Part of my caution comes from having a dysfunctional and overactive immune system, which is altered by a medication I take to control symptoms of rheumatoid arthritis (RA). This medication suppresses a certain part of the immune system that is implicated in the development of RA.  Rheumatoid arthritis primarily attacks the joints, but can also attack the heart, lungs and eyes.

Having to take this particular med (commonly called a biologic), makes me more vulnerable to contracting all types of infection, including covid. It also makes it more difficult to recover from infections and can lead to serious or even deadly complications. 

In addition, the threat of possibly ending up with long covid, when symptoms linger for months or longer, is a concern of mine, especially since fatigue is a major part of long covid syndrome. Profound and disabling fatigue is also a feature of RA and fibromyalgia, so anything I can do to prevent another illness that causes fatigue is important to me. Even mild cases of covid can cause long covid, according to researchers.

Covid can also lead to physical complications. Studies have shown that the virus can cause neurological problems, difficulty breathing, joint or muscle pain, blood clots or other vascular issues, chest pain and unpleasant digestive symptoms.

Furthermore, the virus has been associated with increased psychological problems, such as depression and anxiety. The media has reported on the unfortunate suicides of people who had been suffering from long covid and were unable to get any relief besides ending their own lives.

In the long term, it remains to be seen how covid will affect the millions of us who are already suffering from chronic pain and illness. Fortunately, there are treatments that help with the symptoms and recovery for the majority of people who become infected. There are also medications that can save the lives of those who are at high risk of severe illness.

As more time passes, I’m sure other treatments will emerge, and I’m hopeful that as a chronic pain sufferer with multiple chronic illnesses, I will be okay if I do someday end up getting sick with covid.

Fatigue and Headache Common Symptoms of Long Covid

By Pat Anson, PNN Editor

Fatigue, headache and muscle aches are the most common symptoms reported by people suffering from long covid, according to a comprehensive new study by researchers at the Medical College of Georgia (MCG). Cough, changes in smell and taste, fever, chills and cognitive problems also ranked high on the long list of lingering symptoms from COVID-19.

“There are a lot of symptoms that we did not know early on in the pandemic what to make of them, but now it’s clear there is a long COVID syndrome and that a lot of people are affected,” says lead author Elizabeth Rutkowski, MD, an associate professor of neurology at MCG.

The study findings, published in the journal ScienceDirect, involve the first 200 patients enrolled in the COVID-19 Neurological and Molecular Prospective Cohort Study (CONGA) in Georgia. Participants were recruited on average about four months after testing positive for the COVID-19 virus. Researchers eventually hope to recruit about 500 people for CONGA.

While the findings to date are not surprising and are consistent with what other investigators have learned about long covid, Rutkowski says it was surprising that symptoms initially reported by CONGA participants often didn’t match what further testing found.

For example, the majority of participants reported taste and smell changes, but objective testing of both senses did not always line up with what researchers found. Part of the discrepancy may be a change in the quality of their taste and smell rather than pure impaired ability.

“They eat a chicken sandwich and it tastes like smoke or candles or some weird other thing, but our taste strips are trying to depict specific tastes like salty and sweet,” Rutkowski says.

Eighty percent of the first 200 participants reported neurological problems, with fatigue the most common symptom:

Top Ten Symptoms of Long Covid

1. Fatigue 68.5%

2. Headache 66.5%

3. Muscle aches 57%

4. Cough 55.5%

5. Changes in smell 54.5%

6. Changes in taste 54%

7. Fever 50%

8. Chills 48%

9. Nasal Congestion 47.5%

10. Poor Appetite 47%

Nearly half the participants (47%) met the criteria for mild cognitive impairment, with 30% demonstrating impaired vocabulary, 32% having impaired working memory, and 21% reporting confusion. Researchers believe these cognitive issues may reflect the long-term isolation many participants experienced during the pandemic.

“You are not doing what you would normally do, like hanging out with your friends, the things that bring most people joy,” Rutkowski says. “On top of that, you may be dealing with physical ailments, lost friends and family members and loss of your job.”

Blacks Disproportionately Affected

Nearly two-thirds of the 200 CONGA participants were female, with an average age of 45. Nearly 40% were African-American. One of the study’s goals is to get a better understanding of how COVID-19 impacts African-Americans, who make up a third of Georgia’s population.

Researchers found that Black participants were disproportionately affected by long covid, with 75% meeting the criteria for mild cognitive impairment, compared to only 23.4% of white participants. Blacks were also more likely to have impaired vocabulary and memory. The findings likely indicate that cognitive tests assess different ethnic groups differently and may overestimate cognitive impairment in disadvantaged populations.

“African American patients appear to score significantly worse on quantitative cognitive testing compared to Non-Hispanic White patients, which likely underscore the disparities in how cognitive tests assess different ethnic groups due to various systemic factors including differences is socioeconomic status, psychosocial factors, and physical health,” researchers said.

Previous studies have found that Black and Hispanic individuals are twice as likely to be hospitalized by COVID-19, and ethnic and racial minorities are more likely to live in areas with higher rates of infection.

‘Cognitive Rehab’ May Help Clear Brain Fog

By Judith Graham, Kaiser Health News

Eight months after falling ill with covid-19, the 73-year-old woman couldn’t remember what her husband had told her a few hours before. She would forget to remove laundry from the dryer at the end of the cycle. She would turn on the tap at a sink and walk away.

Before covid, the woman had been doing bookkeeping for a local business. Now, she couldn’t add single-digit numbers in her head. Was it the earliest stage of dementia, unmasked by covid? No. When a therapist assessed the woman’s cognition, her scores were normal.

What was going on? Like many people who’ve contracted covid, this woman was having difficulty sustaining attention, organizing activities, and multitasking. She complained of brain fog. She didn’t feel like herself.

But this patient was lucky. Jill Jonas, an occupational therapist associated with the Washington University School of Medicine in St. Louis who described her to me, has been providing cognitive rehabilitation to the patient, and she is getting better.

Cognitive rehabilitation is therapy for people whose brains have been injured by concussions, traumatic accidents, strokes, or neurodegenerative conditions such as Parkinson’s disease. It’s a suite of interventions designed to help people recover from brain injuries, if possible, and adapt to ongoing cognitive impairment. Services are typically provided by speech and occupational therapists, neuropsychologists and neurorehabilitation experts.

In a recent development, some medical centers are offering cognitive rehabilitation to patients with long covid, who have symptoms that persist several months or longer after the initial infection. According to the Centers for Disease Control and Prevention, about 1 in 4 older adults who survive covid have at least one persistent symptom.

“Anecdotally, we’re seeing a good number of people make significant gains with the right kinds of interventions,” said Monique Tremaine, director of neuropsychology and cognitive rehabilitation at Hackensack Meridian Health’s JFK Johnson Rehabilitation Institute in New Jersey.

Among the post-covid cognitive complaints being addressed are problems with attention, language, information processing, memory, and visual-spatial orientation. A recent review in JAMA Psychiatry found that up to 47% of patients hospitalized in intensive care with covid developed problems of this sort.

Seniors More Vulnerable

There’s emerging evidence that seniors are more likely to experience cognitive challenges post-covid than younger people — a vulnerability attributed, in part, to older adults’ propensity to have other medical conditions. Cognitive challenges arise because of small blood clots, chronic inflammation, abnormal immune responses, brain injuries such as strokes and hemorrhages, viral persistence, and neurodegeneration triggered by covid.

Getting help starts with an assessment by a rehabilitation professional to pinpoint cognitive tasks that need attention and determine the severity of a person’s difficulties. One person may need help finding words while speaking, for instance, while another may need help with planning and yet another may not be processing information efficiently. Several deficits may be present at the same time.

Next comes an effort to understand how patients’ cognitive issues affect their daily lives. Among the questions that therapists will ask, according to Jason Smith, a rehabilitation psychologist at the University of Texas Southwestern Medical Center in Dallas: “Is this showing up at work? At home? Somewhere else? Which activities are being affected? What’s most important to you and what do you want to work on?”

To try to restore brain circuits that have been damaged, patients may be prescribed a series of repetitive exercises. If attention is the issue, for instance, a therapist might tap a finger on the table once or twice and ask a patient to do the same, repeating it multiple times. This type of intervention is known as restorative cognitive rehabilitation.

“It isn’t easy because it’s so monotonous and someone can easily lose attentional focus,” said Joe Giacino, a professor of physical medicine and rehabilitation at Harvard Medical School. “But it’s a kind of muscle building for the brain.”

A therapist might then ask the patient to do two things at once: repeat the tapping task while answering questions about their personal background, for instance.

“Now the brain has to split attention — a much more demanding task — and you’re building connections where they can be built,” Giacino explained.

To address impairments that interfere with people’s daily lives, a therapist will work on practical strategies with patients. Examples include making lists, setting alarms or reminders, breaking down tasks into steps, balancing activity with rest, figuring out how to conserve energy, and learning how to slow down and assess what needs to be done before taking action.

A growing body of evidence shows that “older adults can learn to use these strategies and that it does, in fact, enhance their everyday life,” said Alyssa Lanzi, a research assistant professor who studies cognitive rehabilitation at the University of Delaware.

Along the way, patients and therapists discuss what worked well and what didn’t, and practice useful skills, such as using calendars or notebooks as memory aids.

“As patients become more aware of where difficulties occur and why, they can prepare for them and they start seeing improvement,” said Lyana Kardanova Frantz, a speech therapist at Johns Hopkins University. “A lot of my patients say, ‘I had no idea this could be so helpful.’”

Johns Hopkins has been conducting neuropsychiatric exams on patients who come to its post-covid clinic. About 67% have mild to moderate cognitive dysfunction at least three months after being infected, said Dr. Alba Miranda Azola, co-director of Johns Hopkins’ Post-Acute COVID-19 Team. When cognitive rehabilitation is recommended, patients usually meet with therapists once or twice a week for two to three months.

Before this kind of therapy can be tried, other problems may need to be addressed. “We want to make sure that people are sleeping enough, maintaining their nutrition and hydration, and getting physical exercise that maintains blood flow and oxygenation to the brain,” Frantz said. “All of those impact our cognitive function and communication.”

Depression and anxiety — common companions for people who are seriously ill or disabled — also need attention. “A lot of times when people are struggling to manage deficits, they’re focusing on what they were able to do in the past and really mourning that loss of efficiency,” Tremaine said. “There’s a large psychological component as well that needs to be managed.”

Medicare usually covers cognitive rehabilitation, but Medicare Advantage plans may differ in the type and length of therapy they’ll approve and how much they’ll reimburse providers — an issue that can affect access to care.

Still, Tremaine noted, “not a lot of people know about cognitive rehabilitation or understand what it does, and it remains underutilized.” She and other experts don’t recommend digital brain-training programs marketed to consumers as a substitute for practitioner-led cognitive rehabilitation because of the lack of individualized assessment, feedback, and coaching.

Also, experts warn, while cognitive rehabilitation can help people with mild cognitive impairment, it’s not appropriate for people who have advanced dementia.

If you’re noticing cognitive changes of concern, ask for a referral from your primary care physician to an occupational or speech therapist, said Erin Foster, an associate professor of occupational therapy, neurology, and psychiatry at Washington University School of Medicine in St. Louis. Be sure to ask therapists if they have experience addressing memory and thinking issues in daily life, she recommended.

“If there’s a medical center in your area with a rehabilitation department, get in touch with them and ask for a referral to cognitive rehabilitation,” said Smith, of UT Southwestern Medical Center. “The professional discipline that helps the most with cognitive rehabilitation is going to be rehabilitation medicine.”

Covid’s New Wave: Get Another Booster Shot or Wait?

By Sam Whitehead and Arthur Allen, Kaiser Health News

Gwyneth Paige didn’t want to get vaccinated against covid-19 at first. With her health issues — hypertension, fibromyalgia, asthma — she wanted to see how other people fared after the shots. Then her mother got colon cancer.

“At that point, I didn’t care if the vaccine killed me,” she said. “To be with my mother throughout her journey, I had to have the vaccination.”

Paige, who is 56 and lives in Detroit, has received three doses. That leaves her one booster short of federal health recommendations.

Like Paige, who said she doesn’t currently plan to get another booster, some Americans seem comfortable with the protection of three shots. But others may wonder what to do: Boost again now with one of the original vaccines, or wait months for promised new formulations tailored to the latest, highly contagious omicron subvariants, BA.4 and BA.5?

The rapidly mutating virus has created a conundrum for the public and a communications challenge for health officials.

“What we’re seeing now is a little bit of an information void that is not helping people make the right decision,” said Dr. Carlos del Rio, a professor of infectious diseases at the Emory University School of Medicine.

Del Rio said the public isn’t hearing enough about the vaccines’ value in preventing severe disease, even if they don’t stop all infections. Each new covid variant also forces health officials to tweak their messaging, del Rio said, which can add to public mistrust.

About 70% of Americans age 50 and older who got a first booster shot — and nearly as many of those 65 and older — haven’t received their second covid booster dose, according to data from the Centers for Disease Control and Prevention. The agency currently recommends two booster shots after a primary vaccine series for adults 50 and older and for younger people with compromised immune systems. Last week, multiple news outlets reported that the Biden administration was working on a plan to allow all adults to get second covid boosters.

Officials are worried about the surge of BA.4 and BA.5, which spread easily and can escape immune protection from vaccination or prior infection. A recent study published in Nature found BA.5 was four times as resistant to the currently available mRNA vaccines as earlier omicron subvariants.

Mixed Messages

Consistent messaging has been complicated by the different views of leading vaccine scientists. Although physicians like del Rio and Dr. Peter Hotez of Baylor College of Medicine see the value in getting a second booster, Dr. Paul Offit, a member of the FDA’s vaccine advisory committee, is skeptical it’s needed by anyone but seniors and people who are immunocompromised.

“When experts have different views based on the same science, why are we surprised that getting the message right is confusing?” said Dr. Bruce Gellin, chief of global public health strategy at the Rockefeller Foundation and Offit’s colleague on the FDA panel.

Janet Perrin, 70, of Houston hasn’t gotten her second booster for scheduling and convenience reasons and said she’ll look for information about a variant-targeted dose from sources she trusts on social media. “I haven’t found a consistent guiding voice from the CDC,” she said, and the agency’s statements sound like “a political word salad.”

On July 12, the Biden administration released its plan to manage the BA.5 subvariant, which it warned would have the greatest impact in the parts of the country with lower vaccine coverage. The strategy includes making it easier for people to access testing, vaccines and boosters, and covid antiviral treatments.

During the first White House covid briefing in nearly three weeks, the message from top federal health officials was clear: Don’t wait for an omicron-tailored shot. “There are many people who are at high risk right now, and waiting until October, November for their boost — when in fact their risk is in the moment — is not a good plan,” said Dr. Rochelle Walensky, head of the CDC.

With worries about the BA.5 subvariant growing, the FDA on June 30 recommended that drugmakers Pfizer-BioNTech and Moderna get to work producing a new, bivalent vaccine that combines the current version with a formulation that targets the new strains.

The companies both say they can make available for the U.S. millions of doses of the reformulated shots in October. Experts think that deadline could slip by a few months given the unexpected hitches that plague vaccine manufacturing.

“I think that we have all been asking that same question,” said Dr. Kathryn Edwards, scientific director of the Vanderbilt Vaccine Research Program. “What’s the benefit of getting another booster now when what will be coming out in the fall is a bivalent vaccine and you will be getting BA.4/5, which is currently circulating?”

“There are many people who are at high risk right now, and waiting until October, November for their boost — when in fact their risk is in the moment — is not a good plan. ”

— Dr. Rochelle Walensky, CDC.Director

The FDA on July 13 authorized a fourth covid vaccine, made by Novavax, but only for people who haven’t been vaccinated yet. Many scientists thought the Novavax shot could be an effective booster for people previously vaccinated with mRNA shots from Pfizer-BioNTech and Moderna because its unique design could broaden the immune response to coronaviruses. Unfortunately, few studies have assessed mix-and-match vaccination approaches, said Gellin, of the Rockefeller Foundation.

Edwards and her husband got covid in January. She received a second booster last month, but only because she thought it might be required for a Canadian business trip. Otherwise, she said, she felt a fourth shot was kind of a waste, though not particularly risky. She told her husband — a healthy septuagenarian — to wait for the BA.4/5 version.

People at very high risk for covid complications might want to go ahead and get a fourth dose, Edwards said, with the hope that it will temporarily prevent severe disease “while you wait for BA.4/5.”

The omicron vaccines will contain components that target the original strain of the virus because the first vaccine formulations are known to prevent serious illness and death even in people infected with omicron.

Those components will also help keep the earlier strains of the virus in check, said Dr. David Brett-Major, an infectious disease specialist at the University of Nebraska Medical Center. That’s important, he said, because too much tailoring of vaccines to fight emerging variants could allow older strains of the coronavirus to resurface.

Brett-Major said messages about the value of the tailored shots will need to come from trusted, local sources — not just top federal health officials.

“Access happens locally,” he said. “If your local systems are not messaging and promoting and enabling access, it’s really problematic.”

Although some Americans are pondering when, or whether, to get their second boosters, many people tuned out the pandemic long ago, putting them at risk during the current wave, experts said.

Dr. Georges Benjamin, executive director of the American Public Health Association, said he doesn’t expect to see the public’s level of interest in the vaccine change much even as new boosters are released and eligibility expands. Parts of the country with high vaccine coverage will remain relatively insulated from new variants that emerge, he said, while regions with low vaccine acceptance could be set for a “rude awakening.”

Even scientists are at a bit of a loss for how to effectively adapt to an ever-changing virus.

“Nothing is simple with covid, is it? It’s just whack-a-mole,” said Edwards. “This morning I read about a new variant in India. Maybe it’ll be a nothingburger, but — who knows? — maybe something big, and then we’ll wonder, ‘Why did we change the vaccine strain to BA.4/5?’”

Seniors Often Slow to Recover From Long Covid

By Judith Graham, Kaiser Health News

Older adults who have survived covid-19 are more likely than younger patients to have persistent symptoms such as fatigue, breathlessness, muscle aches, heart palpitations, headaches, joint pain, and difficulty with memory and concentration — problems linked to long covid.

But it can be hard to distinguish lingering aftereffects of covid from conditions common in older adults such as lung disease, heart disease, and mild cognitive impairment. There are no diagnostic tests or recommended treatments for long covid, and the biological mechanisms that underlie its effects remain poorly understood.

“Identifying long covid in older adults with other medical conditions is tricky,” said Dr. Nathan Erdmann, an assistant professor of infectious diseases at the University of Alabama-Birmingham’s school of medicine. Failing to do so means older covid survivors might not receive appropriate care.

What should older adults do if they don’t feel well weeks after becoming ill with the virus? I asked a dozen experts for advice. Here’s what they suggested.

Seek Medical Attention

“If an older person or their caregiver is noticing that it’s been a month or two since covid and something isn’t right — they’ve lost a lot of weight or they’re extremely weak or forgetful — it’s worth going in for an evaluation,” said Dr. Liron Sinvani, director of the geriatric hospitalist service at Northwell Health, a large health system in New York.

But be forewarned: Many primary care physicians are at a loss as to how to identify and manage long covid. If you’re not getting much help from your doctor, consider getting a referral to a specialist who sees long covid patients or a long covid clinic. Also, be prepared to be patient: Waits for appointments are lengthy.

At least 66 hospitals or health systems have created interdisciplinary clinics, according to Becker’s Hospital Review, an industry publication. For people who don’t live near one of those, virtual consultations are often available. For specialist referrals, ask whether the physician has experience with long covid patients.

Also, more than 80 medical centers in more than 30 states are enrolling patients in a four-year, $1.15 billion study of long covid that is being funded by the National Institutes of Health and is known as RECOVER (Researching COVID to Enhance Recovery). Older adults who choose to participate will receive ongoing medical attention.

Seek Comprehensive Care

At the University of Southern California’s covid recovery clinic, physicians start by making sure that any underlying medical conditions that older patients have — for instance, heart failure or chronic obstructive pulmonary disease — are well controlled. Also, they check for new conditions that may have surfaced after a covid infection.

If preexisting and new conditions are properly managed and further tests come back negative, “there is probably an element of long covid,” said Dr. Caitlin McAuley, one of two physicians at the Keck School of Medicine clinic.

At that point, the focus becomes helping older adults regain the ability to manage daily tasks such as showering, dressing, moving around the house, and shopping. Typically, several months of physical therapy, occupational therapy, or cognitive rehabilitation are prescribed.

Dr. Erica Spatz, an associate professor of cardiology at the Yale School of Medicine, looks for evidence of organ damage, such as changes in the heart muscle, in older patients. If that’s detected, there are well-established treatments that can be tried. “The older a person is, the more likely we are to find organ injury,” Spatz said.

At the Shirley Ryan AbilityLab in Chicago, a rehabilitation hospital, experts have discovered that a significant number of patients with breathing problems have atrophy in the diaphragm, a muscle that’s essential to breathing, said Dr. Colin Franz, a physician-scientist. Once inflammation is under control, breathing exercises help patients build back the muscle, he said.

For older adults concerned about their cognition after covid, McAuley recommends a neuropsychological exam. “Plenty of older patients who’ve had covid feel like they now have dementia. But when they do the testing, all their higher-level cognitive functioning is intact, and it’s things like attention or cognitive fluency that are impaired,” she said. “It’s important to understand where deficits are so we can target therapy appropriately.”

Become Active Gradually

Older patients tend to lose strength and fitness after severe illness — a phenomenon known as “deconditioning” — and their blood volume and heart muscles will start shrinking in a few weeks if they lie in bed or get little activity, Spatz said. That can cause dizziness or a racing heart upon standing up.

In line with recent recommendations from the American College of Cardiology, Spatz advises patients who have developed these symptoms after covid to drink more fluids, consume more salt, and wear compression socks and abdominal binders.

“I often hear that going for a walk feels awful,” Spatz said. When returning to exercise, “start with five to 10 minutes on a recumbent bicycle or a rower, and add a couple of minutes every week,” she suggested. After a month, move to a semi-recumbent position on a standard bike. Then, after another month, try walking, a short distance at first and then longer distances over time.

This “go slow” advice also applies to older adults with cognitive concerns after covid. Franz said he often recommends restricting time spent on cognitively demanding tasks, along with exercises, for brain health and memory. At least early on, “people need less activity and more cognitive rest,” he noted.

Reset Expectations

Older adults typically have a harder time bouncing back from serious illness, including covid. But even seniors who had mild or moderate reactions to the virus can find themselves struggling weeks or months later. 

The most important message older patients need to hear is “give yourself time to recover,” said Dr. Greg Vanichkachorn, director of the Mayo Clinic’s Covid Activity Rehabilitation Program in Rochester, Minnesota. Generally, older adults appear to be taking longer to recover from long covid than younger or middle-aged adults, he noted.

Learning how to set priorities and not do too much too quickly is essential. “In this patient population, we’ve found that having patients grit their teeth and push themselves will actually make them worse” — a phenomenon known as “post-exertional malaise,” Vanichkachorn said.

Instead, people need to learn how to pace themselves.

“Any significant health event forces people to reexamine their expectations and their priorities, and long covid has really accelerated that,” said Jamie Wilcox, an associate professor of clinical occupational therapy at the Keck School of Medicine. “Everyone I see feels that it’s accelerated their aging process.”

Consider Vulnerabilities

Older adults who have had covid and who are poor, frail, physically or cognitively disabled, and socially isolated are of considerable concern. This group has been more likely to experience severe effects from covid, and those who survived may not readily access health care services.

“We all share concern about marginalized seniors with limited health care access and poorer overall health status,” said Erdmann, of UAB. “Sprinkle a dangerous new pathology that’s not well understood on top of that, and you have a recipe for greater disparities in care.”

“A lot of older [long covid] patients we deal with aren’t accustomed to asking for help, and they think, perhaps, it’s a little shameful to be needy,” said James Jackson, director of long-term outcomes at the Critical Illness, Brain Dysfunction, and Survivorship Center at Vanderbilt University Medical Center in Nashville, Tennessee.

The implications are significant, not only for the patients but also for health care providers, friends, and family. “You really have to check in with people who are older and vulnerable and who have had covid and not just make assumptions that they’re fine just because they tell you they are,” Jackson said. “We need to be more proactive in engaging them and finding out, really, how they are.”

Long Covid Symptoms Often Overlooked in Seniors

By Judith Graham, Kaiser Health News

Nearly 18 months after getting covid-19 and spending weeks in the hospital, Terry Bell struggles with hanging up his shirts and pants after doing the laundry.

Lifting his clothes, raising his arms or arranging items in his closet leave Bell short of breath and often trigger severe fatigue. He walks with a cane, only short distances. He’s 50 pounds lighter than when the virus struck.

Bell, 70, is among millions of older adults who have grappled with long covid — a population that has received little attention even though research suggests seniors are more likely to develop the poorly understood condition than younger or middle-aged adults.

Long covid refers to ongoing or new health problems that occur at least four weeks after a covid infection, according to the Centers for Disease Control and Prevention. Much about the condition is baffling: There is no diagnostic test to confirm it, no standard definition of the ailment, and no way to predict who will be affected.

Common symptoms, which can last months or years, include fatigue, shortness of breath, an elevated heart rate, muscle and joint pain, sleep disruptions, and problems with attention, concentration, language, and memory — a set of difficulties known as brain fog.

Ongoing inflammation or a dysfunctional immune response may be responsible, along with reservoirs of the virus that remain in the body, small blood clots, or residual damage to the heart, lungs, vascular system, brain, kidneys, or other organs.

Only now is the impact on older adults beginning to be documented. In the largest study of its kind, published recently in the journal BMJ, researchers estimated that 32% of older adults in the U.S. who survived covid infections had symptoms of long covid up to four months after infection — more than double the 14% rate an earlier study found in adults ages 18 to 64. Other studies suggest symptoms can last much longer, for a year or more.

The BMJ study examined more than 87,000 adults 65 and older who had covid infections in 2020, drawing on claims data from UnitedHealth Group’s Medicare Advantage plans. It included symptoms that lasted 21 days or more after an infection, a shorter period than the CDC uses in its long covid definition. The data encompasses both older adults who were hospitalized because of covid (27%) and those who were not (73%).

The higher rate of post-covid symptoms in older adults is likely due to a higher incidence of chronic disease and physical vulnerability in this population — traits that have led to a greater burden of serious illness, hospitalization, and death among seniors throughout the pandemic.

“On average, older adults are less resilient. They don’t have the same ability to bounce back from serious illness,” said Dr. Ken Cohen, a co-author of the study and executive director of translational research for Optum Care, a network of physician practices owned by UnitedHealth Group.

“The challenge is that nonspecific symptoms such as fatigue, weakness, pain, confusion, and increased frailty are things we often see in seriously ill older adults.”

— Dr. Charles Semelka

Applying the study’s findings to the latest data from the CDC suggests that up to 2.5 million older adults may have been affected by long covid. For those individuals, the consequences can be devastating: the onset of disability, the inability to work, reduced ability to carry out activities of daily life, and a lower quality of life.

But in many seniors, long covid is difficult to recognize.

“The challenge is that nonspecific symptoms such as fatigue, weakness, pain, confusion, and increased frailty are things we often see in seriously ill older adults. Or people may think, ‘That’s just part of aging,’” said Dr. Charles Thomas Alexander Semelka, a postdoctoral fellow in geriatric medicine at Wake Forest University.

Ann Morse, 72, of Nashville, Tennessee, was diagnosed with covid in November 2020 and recovered at home after a trip to the emergency room and follow-up home visits from nurses every few days. She soon began having trouble with her memory, attention and speech, as well as sleep problems and severe fatigue. Though she’s improved somewhat, several cognitive issues and fatigue persist to this day.

“What was frustrating was I would tell people my symptoms and they’d say, ‘Oh, we’re like that too,’ as if this was about getting older,” she told me. “And I’m like, but this happened to me suddenly, almost overnight.”

Bell, a singer-songwriter in Nashville, had a hard time getting adequate follow-up attention after spending two weeks in intensive care and an additional five weeks in a nursing home receiving rehabilitation therapy.

“I wasn’t getting answers from my regular doctors about my breathing and other issues. They said take some over-the-counter medications for your sinus and things like that,” he said. Bell said his real recovery began after he was recommended to specialists at Vanderbilt University Medical Center.

Long Covid and Dementia

James Jackson, director of long-term outcomes at Vanderbilt’s Critical Illness, Brain Dysfunction, and Survivorship Center, runs several long covid support groups that Morse and Bell attend and has worked with hundreds of similar patients. He estimates that about a third of those who are older have some degree of cognitive impairment.

“We know there are significant differences between younger and older brains. Younger brains are more plastic and effective at reconstituting, and our younger patients seem able to regain their cognitive functioning more quickly,” he said.

In extreme cases, covid infections can lead to dementia. That may be because older adults who are severely ill with covid are at high risk of developing delirium — an acute and sudden change in mental status — which is associated with the subsequent development of dementia, said Dr. Liron Sinvani, a geriatrician and an assistant professor at Northwell Health’s Feinstein Institutes for Medical Research in Manhasset, New York.

Older patients’ brains also may have been injured from oxygen deprivation or inflammation. Or disease processes that underlie dementia may already have been underway, and a covid infection may serve as a tipping point, hastening the emergence of symptoms.

Research conducted by Sinvani and colleagues, published in March, found that 13% of covid patients who were 65 and older and hospitalized at Northwell Health in March 2020 or April 2020 had evidence of dementia a year later.

Dr. Thomas Gut, associate chair of medicine at Staten Island University Hospital, which opened one of the first long covid clinics in the U.S., observed that becoming ill with covid can push older adults with preexisting conditions such as heart failure or lung disease “over the edge” to a more severe impairment.

“It’s hard to attribute what’s directly related to covid and what’s a progression of conditions they already have,” said Gut.

That wasn’t true for Richard Gard, 67, who lives just outside New Haven, Connecticut, a self-described “very healthy and fit” sailor, scuba diver, and music teacher at Yale University who contracted covid in March 2020. He was the first covid patient treated at Yale New Haven Hospital, where he was critically ill for 2½ weeks, including five days in intensive care and three days on a ventilator.

In the two years since, Gard has spent more than two months in the hospital, usually for symptoms that resemble a heart attack. “If I tried to walk up the stairs or 10 feet, I would almost pass out with exhaustion, and the symptoms would start — extreme chest pain radiating up my arm into my neck, trouble breathing, sweating,” he said.

Dr. Erica Spatz, director of the preventive cardiovascular health program at Yale, is one of Gard’s physicians. “The more severe the covid infection and the older you are, the more likely it is you’ll have a cardiovascular complication after,” she said. Complications include weakening of the heart muscle, blood clots, abnormal heart rhythms, vascular system damage, and high blood pressure.

Gard’s life has changed in ways he never imagined. Unable to work, he takes 22 medications and can still walk only 10 minutes on level ground. Post-traumatic stress disorder is a frequent, unwanted companion.

“A lot of times it’s been difficult to go on, but I tell myself I just have to get up and try one more time,” he told me. “Every day that I get a little bit better, I tell myself I’m adding another day or week to my life.”

Long Covid Symptoms Persist Two Years After Hospitalization

By Pat Anson, PNN Editor

About half the patients who were first hospitalized in China with the COVID-19 virus still had symptoms of pain, fatigue or insomnia two years after being discharged, according to a new study that suggests that long covid may persist long after the initial infection.

Long covid is a poorly understood disorder characterized by body pain, fatigue, cognitive impairment and difficulty sleeping.

Wuhan, China was the epicenter of the COVID-19 pandemic in early 2020, which makes it a good place to study how infections with the original strain of the virus affect patients long-term.

Researchers at the China–Japan Friendship Hospital in Beijing followed nearly 1,200 patients who were hospitalized in Wuhan with acute COVID-19 between January 7 and May 29, 2020, and reassessed them six months, 12 months and two years after discharge.

While their physical and mental health generally improved over time, regardless of disease severity, researchers found that 55% of the Wuhan patients still had at least one Covid symptom after two years, compared to 68% after six months. Many reported a poorer quality of life, less ability to exercise, more mental health problems, and increased use of healthcare services compared to people who were not infected.

“Our findings indicate that for a certain proportion of hospitalised COVID-19 survivors, while they may have cleared the initial infection, more than two years is needed to recover fully from COVID-19,” said lead author Bin Cao, MD, Vice President and Director, Department of Pulmonary and Critical Care Medicine, China-Japan Friendship Hospital

“Ongoing follow-up of COVID-19 survivors, particularly those with symptoms of long COVID, is essential to understand the longer course of the illness, as is further exploration of the benefits of rehabilitation programmes for recovery. There is a clear need to provide continued support to a significant proportion of people who’ve had COVID-19, and to understand how vaccines, emerging treatments, and variants affect long-term health outcomes.”

Nearly 90% of the Wuhan patients were well enough to return to work after two years, despite lingering health problems. Nearly a third (31%) reported fatigue or muscle weakness and sleep difficulties. They were also more likely to report joint pain, palpitations, dizziness, headaches, difficulty breathing, anxiety and depression.

“To the best of our knowledge, this is the longest longitudinal follow-up study of individuals who have recovered from acute COVID-19,” researchers reported in The Lancet Respiratory Medicine.

“Throughout the 2 years after acute infection, hospital survivors with COVID-19 continued to recover in terms of symptomatic sequelae, exercise capacity, mental health, and quality of life, regardless of initial disease severity, but a fairly high burden of symptoms was still seen at 2 years. The COVID-19 survivors had not returned to the same health status as the general population 2 years after acute infection, so ongoing follow-up is needed to characterise the protracted natural history of long COVID.”

More than two years after COVID-19 first appeared in Wuhan, China is having another COVID crisis – this one caused by the Omricon variant of the virus. About 400 million people are currently living under some form of lockdown, with residents of China’s largest city, Shanghai, confined to their homes for weeks.

When Symptoms Linger, Is It Long Covid?

By Nina Feldman, WHYY

Many Americans are discovering that recovering from covid-19 may take weeks or even months longer than expected, leaving them with lingering symptoms like intense fatigue or a racing pulse. But does that mean they have what’s known as long covid?

Though such cases may not always amount to debilitating long covid, which can leave people bedridden or unable to perform daily functions, it is common to take weeks to fully recover.

“There could be more to help people understand that it’s not always a quick bounce back right away after the initial infection,” said Dr. Ben Abramoff, director of the Post-COVID Assessment and Recovery Clinic at Penn Medicine in Philadelphia. “This is still a very significant viral infection, and sometimes it’s just a more gradual recovery process than people’s previous viral illnesses.“

Recent federal health guidelines — which recommend only five days of isolation for those who test positive and are symptom-free — may inadvertently suggest most recoveries are, if not just five days long, pretty quick.

That’s the message I got, at least.

I’ve reported on the coronavirus pandemic since it started, and I thought I knew what an infection would be like for a young, otherwise healthy person like me. I knew even mild cases could develop into long covid. I thought they were relatively rare.

Like many Americans, I found myself slowed by a recovery that took more than a month — far longer than I had expected.

I got covid over Christmas. I was vaccinated and boosted, and my symptoms were mild: sore throat, sinus pressure and headache, extreme fatigue. I felt better after eight days, and I tested negative two days in a row on a rapid antigen test.

Soon after ending isolation, I had dinner with a friend. One glass of wine left me feeling like I’d had a whole bottle. I was bone-achingly exhausted but couldn’t sleep.

The insomnia continued for weeks. Activities that once energized me — walking in the cold, riding an exercise bike, taking a sauna — instead left me intensely tired.

The waves of fatigue, which I started calling “crashes,” felt like coming down with an illness in real time: weakened muscles, aches, the feeling that all you can do is lie down. The crashes would last a couple of days, and the cycle would repeat when I accidentally pushed myself beyond my new, unfamiliar limit.

My colleague Kenny Cooper is also young, healthy, vaccinated, and boosted. He was sick for almost two weeks before testing negative. His symptoms lingered a few more weeks. A persistent cough kept him from leaving the house.

“I just felt like there were weights on my chest. I couldn’t sleep properly. When I woke up, if I moved around too much, I would start coughing immediately,” he said.

Abramoff has seen about 1,100 patients since Penn’s post-covid clinic opened in June 2020. There is no official threshold at which someone officially becomes a long-covid patient, he said.

The clinic takes a comprehensive approach to patients who have had symptoms for months, evaluating and referring them to specialists, like pulmonologists, or social workers who can assist with medical leave and disability benefits.

Those coming to the clinic with symptoms lasting six to eight weeks, Abramoff said, are generally sent home to rest. They will likely get better on their own. He advises patients with lingering symptoms to adopt a “watchful waiting” approach: Keep in contact with a primary care doctor, and take things slowly while recovering.

“You have got to build based on your tolerance,” he said. “People were very sick, even if they weren’t in the hospital.”

A National Institutes of Health-funded study on long covid, called Recover, designates any case with symptoms lasting more than 30 days as long covid.

Dr. Stuart Katz, a New York University cardiologist who is the study’s principal investigator, said he estimates 25% to 30% of the nearly 60,000 covid patients in the study will fit the long-covid criteria.

The 30-day mark is an arbitrary cutoff, Katz said. “There’s this whole spectrum of changing symptoms over time.”

A study published in Nature last year tracked more than 4,000 covid patients from initial infection until symptoms subsided. Roughly 13% reported symptoms lasting more than 28 days. That dropped to 4.5% after eight weeks and 2.3% after 12 weeks, indicating most people with symptoms lasting more than a month will recover within another month or two.

That leaves potentially millions of Americans suffering from a variety of covid symptoms — some debilitating — and a lingering burden on the health care system and workforce.

Recent research from the Brookings Institution estimated that lasting covid symptoms could be responsible for up to 15% of the unfilled jobs in the U.S. labor market.

It took me about six weeks to start feeling better. My crashes got better, slowly, as a result of diligent rest and almost nothing else.

My colleague, Cooper, has also improved. His coughing fits have subsided, but he’s still dealing with brain fog.

The way most studies to date describe long covid would leave us out.

But what I’ve come to think of as my “medium covid” affected my life. I couldn’t socialize much, drink, or stay up past 9:30 p.m. It took me 10 weeks to go for my first run — I’d been too afraid to try, fearing another crash that would set me back again.

Failing to treat covid as a serious condition could prolong recovery. Patients should monitor and care for themselves attentively, no matter how mild the infection may seem, Abramoff said.

“It’s something that could kill somebody who’s in their 70s,” he said. “It’s not nothing.”

Long Covid Research Could Lead to New Treatments for Chronic Pain

By Pat Anson, PNN Editor

About a third of people infected with Covid-19 develop long-term symptoms, such as headaches, persistent muscle pain, joint pain, stomach pain, chest pain and respiratory discomfort. Three years into the pandemic, scientists are finally beginning to understand what causes long covid and how to possibly treat it.

In studies on hamsters infected with Covid-19, researchers at the Icahn School of Medicine found that the virus left behind a gene expression signature in the animals’ dorsal root ganglia – a cluster of nerves in the spinal cord that transmit pain signals from the body to the brain. The signature matched gene expression patterns seen in other forms of chronic pain.

“A significant number of people suffering from long COVID experience sensory abnormalities, including various forms of pain,” said Randal (Alex) Serafini, an MD/PhD candidate. “We used RNA sequencing to get a snapshot of the biochemical changes SARS-CoV-2 triggers in a pain-transmitting structure called dorsal root ganglia.”

Serafini presented his findings at the annual meeting of the American Society for Pharmacology and Experimental Therapeutics in Philadelphia. 

The symptoms experienced by hamsters infected with Covid-19 closely mirrored those of people. Researchers say the hamsters showed a slight hypersensitivity to touch early after the infection, which became more severe over time.

They performed similar experiments with the Influenza A virus to determine if other RNA viruses promote a similar response. Influenza A caused an early hypersensitivity that was more severe, but began to fade after a few days. Four weeks after recovering from the flu, the hamsters had no signs of long-term hypersensitivity.

In contrast, hamsters infected with SARS-CoV-2-showed more hypersensitivity, reflecting symptoms of chronic pain. The pain sensitivity remained even after the hamsters recovered from the initial Covid-19 infection. Further research found that SARS-CoV-2 downregulates the activity of several previously identified pain regulators and a protein called interleukin enhancer binding factor 3 (ILF3) — a potent cancer regulator.

Based on these findings, the researchers hypothesized that mimicking the acute effects of ILF3 could serve as a new pain treatment strategy. To test this theory, they gave laboratory mice suffering from inflammation a clinically tested anti-cancer drug that inhibits ILF3 activity. The drug was very effective at treating their pain.

“Our findings could potentially lead to new therapies for patients suffering from acute and long COVID, as well as other pain conditions,” said Serafini. “We think therapeutic candidates derived from our gene expression data, such as ILF3 inhibitors, could potentially target pain mechanisms that are specific to COVID patients, both acutely and chronically.

“Interestingly, we saw a few cancer-associated proteins come up as predicted pain targets, which is exciting because many drugs have already been developed to act against some of these proteins and have been clinically tested. If we can repurpose these drugs, it could drastically cut down therapeutic development timeline.”

Serafini and his colleagues are now working to identify other compounds that could be repurposed to treat pain, while also keeping an eye out for new compounds that might inhibit ILF3 activity.

“Our study also shows that SARS-CoV-2 causes long-term effects on the body in drastically new ways, further underscoring why people should try to avoid being infected,” he said.

Another study has suggested that long covid appears to be the result of an overactive immune system. Australian researchers identified biomarkers of a sustained inflammatory response in the blood samples of long covid patients – suggesting their immune systems were activated by the virus, but then failed to turn off.

Other studies have found similarities between long covid and autoimmune conditions such as lupus and myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS).  

In addition to widespread body pain, long covid symptoms include fatigue, cognitive impairment and difficulty sleeping.    

Chronic Pain Worsened for Many During Pandemic

By Pat Anson, PNN Editor

Nearly nine out of ten people with chronic pain say their symptoms have either not improved (51%) or gotten worse (36%) during the pandemic, according to a new Harris poll that found nearly half of respondents (44%) experienced delays in getting treatment due to Covid-19.

The online survey of 810 U.S. adults with chronic back or leg pain was conducted in October and November 2021. It was commissioned by Medtronic, which makes spinal cord stimulators and other neuromodulation devices that treat pain.

Nine in ten pain sufferers said pain impacts their lives on a daily basis, with poor sleep (63%) being the most common reported problem. Pain also negatively affects their mental health (60%), exercise habits (53%), mobility and function (51%), ability to enjoy hobbies (44%), social life (32%) and occupation (33%).

Over one in five (22%) said pain impacts their romantic relationships, including being intimate with a partner or spouse.

"This data bears out what we've heard from our clinician customers and patients for two years – the pandemic has been especially hard on those with chronic pain," Charlie Covert, Vice President & General Manager of Interventional Pain Therapies at Medtronic, said in a press release.

The survey found that nearly one in five pain sufferers (17%) said they have canceled a medical appointment or procedure without rescheduling, with the primary reason being fear of Covid-19 exposure. Only a third of surveyed patients (34%) feel comfortable going into a healthcare facility, and 5% say they will never feel comfortable returning to their provider.

The overwhelming majority of respondents (90%) wish there were more treatment options available to manage their pain. While most are aware of traditional treatments such as physical therapy and oral pain relievers, far fewer are familiar with options such as targeted drug delivery (38%) or spinal cord stimulation (34%).

"There is a tangible human cost to deferred procedures and delayed care. As COVID-19 hopefully begins its transition to a more endemic disease, we expect many of these patients to urgently seek relief through new or more effective treatment modalities,” said Covert. “Our survey demonstrated that an overwhelming majority want more treatment options, yet awareness of spinal cord stimulation and targeted drug delivery options remains relatively low."

The pandemic continues to affect the bottom line for Medtronic. Last month, the company said revenue losses were in the “low-double digits” for its neuromodulation and pain therapy devices.

In a conference call with analysts, Medtronic said the surge of omicron infections in January created “acute periods of worker absenteeism” with its customers, suppliers and staff. While conditions are improving, the company expects pandemic-related issues such as inflation, supply chain issues and healthcare worker shortages to linger.

Cognitive Problems Persist in Patients with Long Covid

By Pat Anson, PNN Editor

About 70% of people with long covid have concentration and memory problems several months after their initial infection with Covid-19, according to new research at the University of Cambridge. The severity of the symptoms appears to be linked to the level of fatigue and headache people experienced during their initial illness.

Long covid is a poorly understood disorder characterized by body pain, fatigue, cognitive impairment and difficulty sleeping. About a third of people infected with coronavirus develop symptoms that can last for many months.   

In their study of 181 long covid patients, published in the journal Frontiers in Aging Neuroscience, researchers found that 78% reported difficulty concentrating, 69% had brain fog, 68% experienced forgetfulness, and 60% had trouble finding the right word to use in speech. They also performed poorly in cognitive tests, with significantly lower ability to remember words and pictures.

“This is important evidence that when people say they’re having cognitive difficulties post-COVID, these are not necessarily the result of anxiety or depression. The effects are measurable - something concerning is happening,” said co-author Muzaffer Kaser, PhD, a psychiatrist and researcher at the University of Cambridge. “Memory difficulties can significantly affect people’s daily lives, including the ability to do their jobs properly.”

The findings are further evidence that Covid-19 will have a lasting impact around the world, long after the pandemic subsides. Cambridge researchers say their study supports other findings that suggest society will face a “long tail” of workforce illness due to long covid.

“Long covid has received very little attention politically or medically. It urgently needs to be taken more seriously, and cognitive issues are an important part of this. When politicians talk about ‘Living with COVID’ – that is, unmitigated infection, this is something they ignore. The impact on the working population could be huge,” said senior author Lucy Cheke, PhD, a psychologist and lecturer at Cambridge.

To help understand the cause of the cognitive problems, Cheke and her colleagues investigated other symptoms that might be linked. They found that people who experienced fatigue and neurological symptoms, such as dizziness and headache, during their initial illness were more likely to have cognitive issues later on.

Participants were assigned to carry out multiple tasks to assess their decision-making and memory. These included remembering words on a list, and remembering which two images appeared together. The results revealed a consistent pattern of memory problems in people with long covid -- problems that were more pronounced in those whose initial neurological symptoms were more severe.

“People think that long covid is ‘just’ fatigue or a cough, but cognitive issues are the second most common symptom - and our data suggest this is because there is a significant impact on the ability to remember. There is growing evidence that COVID-19 impacts the brain, and our findings reflect that,” said Cheke.

Study participants were recruited between October 2020 and March 2021, when the Alpha variant and the original form of SARS-CoV-2 were still the dominant forms of the virus.

Very few of the patients had symptoms severe enough to be admitted to a hospital. But even among those who were not hospitalized, researchers found that people with severe initial symptoms were more likely to develop long covid than those with mild symptoms. They also found that people over 30 were more likely to have severe ongoing symptoms than younger ones.

“Infection with the virus that causes COVID-19 can lead to inflammation in the body, and this inflammation can affect behaviour and cognitive performance in ways we still don’t fully understand, but we think are related to an early excessive immune response,” said Kaser.

As is often the case with chronic illness, half of the patients with long covid reported difficulty getting medical providers to take their symptoms seriously, perhaps because cognitive symptoms do not get the same attention as respiratory problems.

The Cambridge study currently has no data on long covid associated with the Delta or Omicron variants of coronavirus, although new patients are being recruited to fill that void. The researchers say more studies are needed to understand the complex effects of Covid on the brain, cognition and mental health.

One way to reduce your risk of long covid is to get vaccinated. A UK study last year found that people who received the Moderna, Pfizer or AstraZeneca vaccines had significantly lower risk of an infection that turns into long covid.
