The Inside Story of Elvis Presley’s Death

By Donna Gregory Burch

When Elvis Presley first hit the music scene during the 1950s, he was both beloved and vilified for the hip-thrusting, leg-shaking and gyrating that changed the art form of musical performance forever.

But what many don’t realize is that Presley’s ability to do those iconic dance moves came with a cost and may have actually contributed to his sudden death in 1977 at the age of 42.

In a new book entitled “The Strange Medical Saga of Elvis Presley,” Dr. Forest Tennant, a retired physician who specialized in pain medicine and addiction treatment, explores the fascinating medical history of Elvis.

Turns out, it wasn’t all those peanut butter, banana and bacon sandwiches that killed him. But what did?

I recently had a chance to interview Tennant about his latest book and what really caused Elvis’ death.  

Donna Gregory Burch: When I think about Elvis’ death, I recall the rumors that he died while taking a bowel movement on the toilet and that his autopsy revealed a very full colon. Are either of those stories actually true?

Forest Tennant: Yes, they are. We knew about these events [surrounding his death], but we had no scientific or medical explanation as to why they occurred. Fifty years after he dies, we finally have a scientific explanation as to why he died like he did.

What happened to him and why he died so suddenly in the bathroom was … a medical controversy that … ended up in a criminal trial and with all kinds of emotionalism.

Nothing happened to Elvis Presley that we don't have a good logical, scientific explanation for now. But certainly back in those days we didn't.  

You were involved in a court proceeding about Elvis’ death. Could you tell me about that and what role you served during the lawsuit?

Well, what happened was that because he died suddenly and because the pathologists couldn't agree on why he died, and because Elvis was found to be abusing drugs as well as being prescribed a lot of drugs, a criminal trial was brought against his physician (Dr. George Nichopoulos).

The attorney that decided to defend (Nichopoulos) was a man by the name of James Neal, who was a federal prosecutor who prosecuted Jimmy Hoffa and the offenders in the Watergate scandal, and so he was the nation's top attorney at that time. He investigated the case and found out that the doctor that treated Elvis Presley was not a criminal at all and was doing his best to help him.

Some dozen physicians at the Baptist hospital in Memphis saw Elvis Presley, but nobody knew what was the matter with him. They knew he had some kind of mysterious, systemic disease, which is a disease that can affect multiple organs at the same time.

He was a baffling medical case for the doctors in Memphis at that time, and we didn't know what he had up until about three or four years ago. We did not understand the genetic collagen connective tissue disorders, now usually referred to by doctors as Ehlers Danlos syndrome (EDS). Nobody understood that his glaucoma and his colon [issues] were connected [due to EDS]. They knew it was connected somehow but they didn't have an explanation for it at that time.

What do we know today about why Elvis died that we could not explain back when he actually passed away?

He had a severe heart problem.

Elvis’ heart problem was directly tied to his diet, right? I mean he was well-known for his fat and sugar-laden diet.

Yes, his diet was part of it, but his autoimmunity also affected his heart.

But the major controversy of the day is one that's maybe a little hard for the public to understand. A drug overdose in 1977 was said to only occur if the lungs filled up with fluid. He had no fluid in his lungs, so the only thing that he had at his autopsy of any significance was a huge heart. And so the pathologist and the county medical examiner said he had to have died of a heart attack because his heart was so bad.

The catch was that he had about 11 drugs in his bloodstream. The highest level was codeine, so there became a dispute among the doctors. A certain group of pathologists who were highly qualified said he died of a heart problem. Another group of highly qualified physicians who were called forensic pathologists said no, he died of his drugs. Up until about two or three or four years ago, the argument was still going on.

Now, I hate to say thanks to the opioid crisis, but because of the overdose deaths that have occurred in recent years, a lot of studies have been done, and enzymes have been discovered, and metabolism has been discovered showing that drugs like codeine can cause a certain heart stoppage without having pulmonary edema (fluid filling the lungs].

It turns out that 24 hours before he died, a dentist gave him codeine. He was already thought to be allergic to it anyway, and that was because he had all these metabolic defects due to his genetics, and so the codeine built up in his system. He had this terrible heart, so he died suddenly, within seconds, as he was trying to sit on the commode. He fell forward.

There is a forensic pathologist, the best one of the day, called Dr. Joseph Davis, and in about 1997, he described exactly, second by second, what happened to Elvis in the bathroom. But the cause is pretty clear: He took the codeine, and it caused a cardiac arrhythmia. If he had a good heart, he might have survived, but he had a bad heart.

So, it’s really a combination. You had these two sides of doctors arguing – they even ended up in a criminal trial – but it turns out that they were both right. It was a combination of a terrible heart and a drug that causes cardiac arrhythmia, and that's why he died with no pulmonary edema.

So many times in the medical community, we always look for that one cause, right? His case is very illustrative. Because the body is so complex, it's often multiple factors that are causing health issues.

Elvis Presley had multiple diseases. He was terribly ill, and he died accidentally in some ways with a dentist giving him codeine for his bad tooth, and his bad teeth were also part of the same disease that gave him a bad colon and a bad eye and a bad liver. They were all connected.

EDS is what connects all of those health problems, correct?

Yes, scientifically, EDS is a genetic connective tissue collagen disorder, and what that means is that you are genetically predetermined to have your collagen in certain tissues either disappear or deteriorate or become defective, and to put it bluntly, you can have a rectal problem and an eye problem at the same time due to the same cause because your collagen is deteriorating in these tissues, and you were programmed to develop this when you are born. It is a major cause of the intractable pain syndrome.

Now some of the diseases are very mild. You have a little double jointedness, and your skin is a little lax, and you might develop some arthritis, but you become a good gymnast in the Olympics or you become a good football player in some of the mild cases. But if you get a severe case like Elvis Presley, your life is going to be very miserable, and you're going to die young unless you get vigorous treatments, which are being developed right now.

I don't think EDS was even recognized back when Elvis was living, was it? It wasn't even a known diagnosis. Not many people even know about it today.

No, Dr. Peter Beighton didn't even come up with the (diagnostic screening tool for EDS) until long after Elvis Presley died.

As amazing as it may seem, I'm the only person in the United States who had the autopsies of both Elvis Presley and [aviator and businessman] Howard Hughes and their medical records, and was able to interview their physicians who took care of them. So I felt obligated to put these into books. I don't care whether anybody buys the books or not, but I do think these cases are marvelous cases, and I think these are icons and heroes of the last century, and somebody needed to write it down, and I'm the only one who had the material.

And you know something? For 50 years nobody cared that I had them. Maybe they still don't, but I've got them in the books now, so it'll be recorded for posterity, and that was my goal … to make sure that history is recorded.

Was EDS responsible for the way Elvis was able to move and dance?

Yes, we've got some pictures in the book, and I think we put the question in there. Can you hold these positions and sing and hold a microphone at the same time? And of course, [most people] can't. [EDS was] why he was able to do those things.

But on the other hand, we [recently had] the Olympics, and some of those Olympic [athletes] couldn't possibly do this if they didn't have these hypermobile joints. Whether they will develop the disease in later life is unknown.

When you're young, and you have these joints that are hyperextended, you can do things that other people can't do.

In your recent book about Howard Hughes’ medical issues, you had written about how Hughes was still very successful in life despite the fact he was in an enormous amount of chronic pain due to his medical conditions. Elvis was in the same predicament, wasn’t he?

Very much so, and I'm hoping that people who have intractable pain syndrome, who have EDS, complex regional pain syndrome, autoimmune diseases and traumatic brain injuries, read these books or at least hear about the books, and get some hope and realize that here are two men who did great things in very disparate fields but were terribly ill. I've had many, many patients who read about Howard Hughes tell me that he was an inspiration to them.

Elvis was in a great deal of chronic pain as a result of his EDS. Is that what led to his addiction to opioids?

Yes, we will never quite know how much of the drug taking that Elvis was doing was him self-treating his medical condition and how much of it was just abuse, but that's just the way it is. You can't quantitate it.

I was actually asked to deal with both of these cases because, back in the 1970s, I was trying to deal with patients who appeared to abuse opioids and other drugs and also had legitimate pain, and that's how I got involved with these cases.

It's an issue to this day, and society can't deal with it. They just refuse to talk about it, refuse to deal with it. You've got one group of doctors who just want to treat the addiction. You've got another group who just want to treat the pain, but you've really got to treat some of both and have doctors who understand both, but at this point in time, it's not happening.

I would love to see these books bring about some rational discussions about opioids and about pain and addiction, but I don't see it happening. I see nothing but controversy, accusation, falsehoods, fabrications. Society and the media can't seem to have rational discussions anymore about these issues, unfortunately.

I think with all of Elvis’ health issues and his subsequent drug addiction, it was almost like the perfect storm, right? He has EDS that's causing him extreme pain. The doctors give him pain medications to try to remedy that, so he can actually perform on stage, but then he’s still not able to perform up to the standards of his fans because of his addiction to those drugs.

He was really in a damned if you do, damned if you don’t predicament.

Yes. Also, these drugs probably caused him to have a terrible traumatic brain injury. We couldn't document it, but I suspect that's what happened. He did have a terrible traumatic brain injury, which accelerated all his other problems.

Yes. Apparently, he had fallen in a bathroom and had injured his head, and that was part of what was going on with him in the last years of his life as well.

Yes, it sure was. So again as you pointed out, it was the perfect storm. That's exactly what happened.

You know what I think is so interesting about these two books that you've written? We as the public have this view of Howard Hughes that he was a recluse because he was eccentric and that was just part of his personality. But he was actually really suffering a great deal from chronic pain.

And it's the same situation with Elvis. When we think about his death, we think he was just a drug addict who took too many pills one night, fell off the toilet and died, right? But Elvis was also living with extreme pain and suffering, and he was likely just trying to medicate himself out of that misery.

In our research studies, I saw four people yesterday who have EDS as well as spinal canal problems, and they're just miserable. I sometimes don't know how Elvis and Howard Hughes and the people I hear from daily, I don't know how they make it, you know? I marvel at it.

I'm hoping that everybody who's got intractable pain syndrome or EDS or traumatic brain injuries reads these books. That's who they're written for.

Why did you think it was important to write for those audiences?

I think that the audiences that we deal with are terribly neglected in society. I hate to say it, but I think people who have intractable pain are disdained by a great segment of the population. They're ignored by the political structure, neglected by the medical profession. I hate to say it, but the people we deal with, somebody has got to look after them.

My wife and I… we've managed to put together a foundation and use our business successes to try to help people, and I think that's not normal either. My study of the best physicians over time have been doctors who stepped up to the plate for people who needed it because nobody else in society is going to.

I feel sorry for all the groups that have been out lobbying their legislators, their politicians, their medical boards, and they get deaf ears. They get nothing but yes, yes, yes, but then nothing happens. The medical profession we have, it doesn't stand up for people with intractable pain syndrome or EDS, and that is because a huge part of the medical profession is based on treating well people or simple problems.

And so these are people in society who are disdained, neglected and abused, and are put in the corner by huge segments of not only society at large and the government, but also by the medical profession itself.

Yes, I understand exactly what you're saying. I've encountered it myself as a chronic pain patient.

I bet you do.

Any final thoughts?

I have read I don’t know how many books on Howard Hughes and Elvis Presley, and almost all of them are antagonistic. They are hostile. They blame somebody. They are looking for something that's bad, okay?

And I don't know whether it's the authors. I don't know whether it's their publishers. I can't tell you, except I know one thing: In my review of Howard Hughes and Elvis Presley, and like I say, I'm the last person who knew their doctors and had any real contact with their physicians and even the media, I don't see all this negativism.

I think people as a group try to deal with the Elvis affair legitimately, honestly and with care, and the idea that somebody should be blamed, somebody should be bad-mouthed, it's just not there.

These are great stories. They're tragic stories, but I think there are an awful lot of positive, really good things that happened to these men and to people who were around them, so I don't think we're going to get anywhere dealing with some of these issues with just total negativism.

And I think the whole situation, if you read it, is somewhat uplifting and motivating. We are here to try to help our fellow man and women have better lives, and I think there's a lot of that in both of these men.

Widespread Pain Raises Risk of Dementia and Stroke

By Pat Anson, PNN Editor

Widespread body pain caused by fibromyalgia and other chronic pain conditions raises the risk of stroke and dementia, including Alzheimer’s disease, according to a new study.

Researchers looked at health data for nearly 2,500 second generation participants in the long-running, community-based Framingham Heart Study. Participants in the “offspring” phase of the study were given a comprehensive check-up that included a physical exam, lab tests and detailed pain assessment when they enrolled in the early 1990’s. They were then reassessed every four years for signs of cognitive decline, dementia or stroke.

Over the next two decades, 188 of the participants were diagnosed with some form of dementia and 139 had a stroke.

While the number of cases was small, researchers found an association between pain and cognitive decline. Participants with widespread pain were 43% more likely to have some type of dementia, 47% more likely to have Alzheimer’s disease, and 29% more likely to have a stroke compared to those without widespread pain (WSP). 

“These findings provide convincing evidence that WSP may be a risk factor for all-cause dementia, AD dementia (Alzheimer’s), and stroke,” researchers concluded. “While it is known that chronic pain or persistent pain without detailed classification is associated with poorer cognitive performance in cross-sectional or cohort studies, our study was based on much more accurate assessments for pain at a longitudinal population level. The specific presence of WSP… has long-term implications for dementia and AD.”

The researchers said there were three possible explanations for the link between pain and cognitive decline. First are lifestyle factors associated with pain, such as reduced physical activity, poor diet, alcohol and weight gain. Second is that stress caused by widespread pain may impair cognitive function; and third is that WSP may be a “preclinical phase” of dementia and AD.

Previous studies have also linked chronic pain to dementia. A large 2017 study found that older people with chronic pain experience faster declines in memory and are more likely to develop dementia. A more recent study suggests that people with chronic pain are at higher risk of memory loss and cognitive decline if they have lower levels of education, income and access to healthcare.

Antidepressants, anti-psychotics, antihistamines and other common medications may also cause confusion and disorientation that is mistaken for dementia, especially in older adults. When patients are taken off the drugs, their cognitive function may improve.  

Previous studies have also linked widespread pain to cancer, peripheral arterial disease, cardiovascular disease and increased mortality.

Pioneering Neurologist and CRPS Expert Remembered

By Pat Anson, PNN Editor

A pioneering neurologist who helped develop new treatments for Complex Regional Pain Syndrome (CRPS) has died. Robert Schwartzman, MD, passed away last week at the age of 81.

Dr. Schwartzman was an emeritus professor and former chair of the Department of Neurology at Drexel University College of Medicine in Philadelphia. He also taught and practiced medicine at Thomas Jefferson University, University of Texas Health Science Center, San Antonio and the University of Miami. He mentored hundreds of residents and colleagues, and authored several reference books on neurology.

The primary focus of Schwartzman practice and research was chronic pain, particularly CRPS (also known as Reflex Sympathetic Dystrophy or RSD), a chronic and severe pain syndrome affecting the nervous system.

At Jefferson University, Schwartzman founded the first CRPS clinic in the U.S. and pioneered the use of ketamine as a treatment for CRPS and other pain conditions.

“I met Dr Schwartzman in 2007 at a pain conference and joined the wait list to see him as my provider for RSD. I was finally able to so do in 2009. I shared what I learned with as many people as I could and continue to this day,” says PNN columnist Barby Ingle, founder and president of the International Pain Foundation. “His impact will live on through patients like me.”

DR. ROBERT SCHWARTZMAN

Ingle wrote about her first experience as a patient of Schwartzman in a PNN column. She went into the hospital in a wheelchair, but was able to walk out a week later after a series of ketamine infusions. She continues to get infusions regularly.

“He was a brilliant doctor and world expert on Reflex Sympathetic Dystrophy who's training and 40+ years of research help teach other providers who have also gone on to help millions of patients,” Ingle said in an email. “He will forever live in my heart as he is the provider who got me from my wheelchair and bed bound to walking and living life to my fullest. I will continue sharing his pioneering works and receiving his protocol for my infusion therapy. He is a treasure to our whole community.”   

“I didn't know him personally but I knew and respected his pioneering work,” says Lynn Webster, MD, past president of the American Academy of Pain Medicine. “He challenged our thoughts and understanding about how to treat the devastating disease of CRPS.  

“Dr. Schartzman took us into unexplored areas of how to treat a crippling disease. His work inspired me and countless others who have tried to implement his treatment approach for our own patients. He has given us a legacy of research that will be the foundation on which new discoveries about the mechanism and cure for CRPS will occur. The passing of Dr. Schwartzman is a huge loss for science and humanity.”

Schwartzman retired from clinical practice in 2013 and moved to Marco Island, Florida. Funeral arrangements are private. His family requests that any donations in his memory be made to any Florida wildlife or conservation charity.

Nearly 60% of Americans Live with Pain

By Pat Anson, PNN Editor

Nearly 60 percent of U.S. adults have some type of short or long-term pain, according to a new CDC report that found the prevalence of pain steadily increases with age and is highest among adults aged 65 and older. Being female, white or poor also increased the likelihood of pain.

The CDC study is based on data from the 2019 National Health Interview Survey, in which participants were asked if they felt pain “some days,” “most days” or “every day” in the last 3 months.

Back pain (39%) was the most common site for pain, followed by pain in the hips, knees or feet (36.5%); hands, arms and shoulders (30.7%); and head pain (22.4%). About ten percent of those surveyed said they had abdominal or dental pain.

U.S. Adults With Pain in Last 3 Months

SOURCE: cdc

“Overall, nearly three in five adults (58.9%) experienced pain of any kind in the past 3 months in 2019,” researchers reported. “Location-specific pain, such as back, neck, arm, and hip pain is associated with short- and long-term health effects, ranging from minor discomfort to musculoskeletal impairment, diminished quality of life, and escalating health care costs.”

Household income appears to play a role in pain prevalence. Nearly 45% of people living in a household below the 2019 federal poverty level ($25,750 for a family of four) reported having back pain. For people with household income at least 200% higher, the rate of back pain was 37.6 percent. The association between pain and poverty was similar for people with pain in their upper and lower limbs.

The study findings are similar to the so-called “deaths of despair” first reported in 2015 by Princeton researchers Angus Deaton and Anne Case, who found that financial and emotional stress caused by unemployment and stagnant incomes may be behind the reduced life expectancy of middle-aged white Americans.

Between 1999 and 2013, the mortality rate for middle aged whites rose by 2 percent, coinciding with an increase in fatal overdoses. No other race or ethnic group saw such an increase in mortality. The rising death rate for whites was accompanied by more suicides and substance abuse, as well as increases in joint pain, neck pain, sciatica and disability.

One critic of the “deaths of despair” theory is Andrew Kolodny, MD, the founder of Physicians for Responsible Opioid Prescribing (PROP).  Kolodny in a recent webinar claimed that overdoses were driven by drug addiction, not socioeconomic factors.

“The deaths of despair framing, while provocative, is unlikely to explain the main sources of the fatal drug epidemic and that efforts to improve economic conditions in distressed locations, while desirable for other reasons, are not likely to yield significant reductions in drug mortality,” Kolodny said.

Kolodny and at least three other PROP board members have been well-paid expert witnesses in opioid litigation cases – lawsuits that depend on a public narrative that excess opioid prescribing led to the overdose crisis, not mental health problems or economic disparity. Maintaining that narrative is becoming harder, with opioid prescribing at 20-year lows and overdose deaths at record highs, fueled in part by economic and social issues exacerbated by the covid pandemic.

How Chronic Pain Disrupts Emotions

By Pat Anson, PNN Editor

Does waking up with pain everyday put you in a bad mood? Do you lose your temper easily or worry a lot?

It could be a sign that chronic pain has created a chemical imbalance in your brain that makes it harder for you to keep negative emotions in check, according to a new study by Australian researchers.

“Chronic pain is more than an awful sensation,” says senior author Sylvia Gustin, PhD, a neuroscientist and associate professor at the University of Sydney’s School of Psychology. “It can affect our feelings, beliefs and the way we are. 

“We have discovered, for the first time, that ongoing pain is associated with a decrease in GABA, an inhibitive neurotransmitter in the medial prefrontal cortex. In other words, there's an actual pathological change going on.”

Gustin and her colleagues at Neuroscience Research Australia (NeuRA) used advanced neurological imaging to scan the brains of 48 people. Half of them lived with a chronic pain condition, while the other half had no history of chronic pain and served as a control group.

Their findings, recently published in the European Journal of Pain, showed that participants with chronic pain had significantly lower levels of GABA than the control group – a pattern that was consistent regardless of the type of chronic pain. 

Neurotransmitters help communicate and balance messages between cells in the brain and central nervous system. While some amplify signals (excitatory neurotransmitters), others weaken them (inhibitive neurotransmitters). GABA, or γ-aminobutyric acid, is one of the latter. It acts in the brain as emotional regulator that helps dial down our emotions.

“A decrease in GABA means that the brain cells can no longer communicate to each other properly,” Gustin explained in a news release. “When there’s a decrease in this neurotransmitter, our actions, emotions and thoughts get amplified.”

While the link between chronic pain and decreased levels of GABA has previously been found in animals, this is the first time it’s been demonstrated in humans. Gustin hopes the findings will encourage people with chronic pain who may be experiencing mental health issues. 

“It's important to remember it’s not you – there’s actually something physically happening to your brain,” she says. “We don't know why it happens yet, but we are working on finding solutions on how to change it.”

GABA is not the only neurotransmitter that’s impacted by chronic pain. In a previous study, Gustin and her research team found that levels of glutamate, the main excitatory neurotransmitter, are also lower than average in people with chronic pain. Low glutamate levels are linked to increased feelings of fear, worry and negative thinking.

“Together, our studies show there's really a disruption in how the brain cells are talking to each other,” says Gustin. “As a result of this disruption, a person’s ability to feel positive emotions, such as happiness, motivation and confidence may be taken away – and they can’t easily be restored.” 

Medication can help relieve chronic pain, but there are currently no drugs that directly target GABA and glutamate levels in the brain. Gustin and her team are developing an online emotional recovery program as a non-pharmaceutical option for treating neurotransmitter disruption. 

“The online therapy program teaches people skills to help self-regulate their negative emotions,” says Gustin. “The brain can't dampen down these feelings on its own, but it is plastic – and we can learn to change it.”

Rare Disease Spotlight: Transverse Myelitis

By Barby Ingle, PNN Columnist  

This month as part of my series on rare diseases and conditions, we’ll look at transverse myelitis (TM), an inflammatory disease of the spinal cord. TM causes pain, muscle weakness, numbness, tingling, and bladder and bowel dysfunction. Severe cases can even result in sudden paralysis. 

Can you imagine being fine one minute and the next being paralyzed and losing control of your bowels?

The most famous person I have heard of having transverse myelitis is Allen Rucker, an author and comedy writer who developed TM spontaneously at the age of 51. Rucker wrote a memoir about becoming paralyzed due to TM: “The Best Seat in the House: How I Woke Up One Tuesday and Was Paralyzed for Life.”

As with many TM patients, Rucker was paralyzed from the waist down and has no control over his legs, bladder or bowel. He will need a wheelchair for the rest of his life. Despite these challenging conditions, Rucker continues to write and uses his communication skills to help others understand what it is like to live with a rare disease.

Transverse myelitis can occur at any age, but most often affects patients between the ages of 10-19 and 30-39. Some people do recover from TM, but the process can take months or even years. Most see improvement in their condition within the first 3 months after the initial attack, giving them a good idea of what they will face long-term.

There are many different causes of transverse myelitis, including viral, bacterial or fungal infections that attack the spinal cord. The inflammatory attack usually appears after recovery from an infection, such as chickenpox, herpes or shingles. TM can also be caused by immune system problems or myelin disorders, such as multiple sclerosis.

Patients who develop transverse myelitis can go through many treatments, including intravenous steroids for days to weeks at a time, plasma exchange therapy, antiviral medication, pain relievers, and drugs used to treat complications. There are some preventative medications to help keep inflammation down, avoid new flares and long-term complications.  

A patient can expect to undergo multiple MRIs of the spine as well as blood testing and possibly a spinal tap to check cerebrospinal fluid. They may also be started on physical therapy, occupational therapy and psychotherapy.

It can be difficult to know the course an individual with TM might take, but they fall into three areas: no or slight disability, moderate disability and severe disability.  The sooner that proper treatments begin for TM, the better the outcomes can be.

If you suspect you might have TM, keep track of when the symptoms started, what they are and how fast they progressed. Note if they presented through pain, tingling or other unusual sensations such as loss of bladder and bowel control or difficulty breathing. A provider will also want to know if you have recently traveled or had any infections or vaccinations.

If you are diagnosed with transverse myelitis, you can find support at the Siegel Rare Neuroimmune Association, a non-profit that advocates for people with TM and other neuroimmune disorders. They are a great resource for those who need assistance for research and daily living. Facebook also has several TM support groups, such as Transverse Myelitis Folks and Transverse Myelitis Society.

We are now halfway through our series on rare diseases and conditions. So far, I have covered transverse myelitis, Paget’s disease, Alexander disease, X-linked Hypophosphatemia, cauda equina syndrome, vulvodynia and Dupuytren's contracture. Next month I will look at Friedreich’s Ataxia.

How Chronic Pain Can Lead to Autoimmunity Problems

By Forest Tennant, PNN Columnist

Every chronic pain patient must know and understand autoimmunity and how to combat it. Research on chronic pain has unequivocally determined that the chronic inflammation and tissue destruction caused by a painful disease or injury will produce autoimmunity.

Autoimmunity is a biologic phenomenon in which certain antibodies in the blood -- called autoantibodies -- turn against the body and attack one’s own tissues. Autoantibody means “self-attack.” This is in stark contrast to “immunity” which means antibodies only attack an invading virus, bacteria, poison or contaminant to protect the body.

Chronic pain that causes inflammation and tissue degeneration generates cellular destruction that can shed tissue particles into the blood stream. These tissue particles are considered foreign and unwanted by the body’s immune system, so it makes autoantibodies against them. Unfortunately, these autoantibodies may then attack normal tissue, giving the patient unexpected symptoms and more pain.

The symptoms and sequelae of autoimmunity can be mysterious and overwhelming. Such disorders as traumatic brain injury, Ehlers-Danlos Syndrome, adhesive arachnoiditis, post-viral, and stroke are particularly prone to the development of autoimmunity.

Although antibodies may attack any tissue in the body, autoantibodies seem to attack the soft tissues such as membranes around organs, ligaments, cartilage, small nerves and intervertebral discs. Another common target is the body’s natural immune protection system, including lymph nodes, thymus gland, mast cells and spleen.

The complications of autoimmunity usually begin without warning. Common clinical manifestations of autoimmunity and the presence of autoantibodies include allergies, skin rash, fibromyalgia, psoriasis, thyroiditis, carpal tunnel syndrome, and arthritis of the joints including the temporal mandibular, elbow and hand joints.

Serious painful and life-threatening autoimmune conditions may also occur, which include the kidney (glomerulonephritis), liver (hepatitis), nerves (neuropathy), spinal canal (arachnoiditis), adrenal gland and the pituitary gland. We now believe that autoimmunity, along with excess neuroelectric stimulation, to be the cause of Intractable Pain Syndrome (IPS).

How To Tell If You Have Autoimmunity

Every chronic pain patient needs to do a self-assessment to determine if their basic pain problem has caused autoimmunity. A failure to control autoimmunity will likely result in progressive complications, misery and probably an early death. As with most other medical conditions, the earlier the recognition, the better the control, suppression and outcome.

Patients should review the following list of some common autoimmune symptoms or conditions. If you have two or more, an assumption can be made that you have autoimmunity and must take actions to control and suppress it:

• Joint pain

• Carpal tunnel

• Histamine episodes or mast cell stimulation

• Cold hands (Raynaud’s)

• Allergies

• Mild recurring fever

• Neuropathy

• Medications stop working

• Irritable Bowel Syndrome (IBS)

• Food or Medication Sensitivity

• Hashimotos Thyroiditis

• Brain Fog

• Fibromyalgia

• Diarrhea, gastric upset, heartburn

• Periodic flushing and itching

• Herniated disc

• Constipation

• Psoriasis

• Exhaustion and Weakness

If you have two or more of these conditions, a laboratory blood test can help confirm it. Autoimmunity and its close association with chronic inflammation, immune suppression and allergy will almost always result in elevations of one or more of the following blood tests:

• C-reactive protein (CRP)

• Lymphocytes or eosinophiles

• Anti-nuclear antibody (ANA)

Automimmunity may also result in decreased immunoglobulins and an altered albumin-globulin ratio.

At this time there is no specific, published treatment for chronic pain-induced autoimmunity. Based on our early investigations, we recommend patients take vitamins, supplements, low dose corticosteroids, low dose naltrexone (LDN) and hormone therapy to control and suppress autoimmunity.

Experimental Brain Implant Automatically Relieves Pain

By Pat Anson, PNN Editor

An experimental brain implant that automatically detects and relieves pain in laboratory animals has the potential to be adapted for human use, according to researchers at NYU Grossman School of Medicine. The computerized device is the first of its kind to target both acute and chronic pain, and may also be effective in treating anxiety, depression, panic attacks and other brain-based disorders.

“Our findings show that this implant offers an effective strategy for pain therapy, even in cases where symptoms are traditionally difficult to pinpoint or manage,” said senior author Jing Wang, MD, an Associate Professor of Anesthesiology at NYU Langone Health.

The technology, known as a closed-loop brain-machine interface, detects brain activity in the anterior cingulate cortex, a region of the brain that is critical for pain processing. A computer linked to the device identifies pain signals in real-time, triggering a therapeutic stimulation of another region of the brain, the prefrontal cortex, to ease pain sensations.  

Wang and his colleagues installed the tiny electrodes in the brains of dozens of rats and then exposed them to carefully measured amounts of pain. The animals were closely monitored to see how quickly they moved away from a source of acute pain.

The study findings, published in the journal Nature Biomedical Engineering, showed that rats withdrew their paws 40 percent more slowly from the pain source when the device was turn on. In addition, animals in acute or chronic pain spent about two-thirds more time in a chamber where the device was turned on than in another chamber where it was not.

Researchers say the implant accurately detected pain up to 80 percent of the time. Since the device is only activated in the presence of pain, it lessens the risk of overuse, tolerance and addiction.

“Our results demonstrate that this device may help researchers better understand how pain works in the brain,” says lead investigator Qiaosheng Zhang, PhD, a doctoral fellow in the Department of Anesthesiology, Perioperative Care and Pain at NYU Langone. “Moreover, it may allow us to find non-drug therapies for other neuropsychiatric disorders, such as anxiety, depression, and post-traumatic stress.”

Zhang says the implant’s pain-detection properties could be improved by installing electrodes in other regions of the brain besides the anterior cingulate cortex. He cautions, however, that the technology is not yet suitable for use in people. Researchers are investigating whether less-invasive forms of the implant can be adapted for human use.

Brain implants – also known as deep brain stimulators -- are currently used to prevent seizures and tremors in people with Parkinson’s disease and epilepsy.

Are NSAIDs Really Better Than Opioids for Post-Operative Pain?

By Pat Anson, PNN Editor

There have been a rash of recent studies promoting the use acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) over opioids for post-operative pain.

One such study at a Houston hospital led surgeons to conclude that patients were better off with Tylenol. "This study provides us with a strategy to successfully manage pain after surgery using over-the-counter pain medication,” said Min Kim, MD, head of thoracic surgery at Houston Methodist Hospital.  

But critics point out that most of the studies never examine how patients feel about the effectiveness of their pain treatment — focusing instead on the number of opioid pills and smaller opioid doses being prescribed. Pain relief was a secondary consideration, if it was considered at all.

A rare exception to that is a study recently published in the Canadian Medical Association Journal (CMAJ), which found that ibuprofen and other NSAIDs gave better post-operative pain relief than the opioid codeine. In a systematic review of 40 clinical trials involving over 5,000 patients who had outpatient procedures, researchers said patients who took NSAIDs had lower pain scores 6 and 12 hours after surgery than patients taking low doses of codeine.

"In all surgery types, subgroups and outcome time points, NSAIDs were equal or superior to codeine for postoperative pain," wrote lead author Matthew Choi, MD, Associate Professor of Surgery at McMaster University in Ontario. "We found that patients randomized to NSAIDs following outpatient surgical procedures reported better pain scores, better global assessment scores, fewer adverse effects and no difference in bleeding events, compared with those receiving codeine.

“These findings are of general importance to any clinician performing painful medical procedures. The various trials in our meta-analysis evaluated a range of procedures, different NSAID types and various degrees of acetaminophen coadministration.”

But critics say the McMaster study also has flaws. The claim that “all surgery types” and “a range of procedures” were included in the analysis is misleading at best. Most of the studies — 28 of the 40 that were analyzed — involved dental surgery, a fact that is not sufficiently disclosed. The rest of the outpatient procedures were for plastic surgery and orthopedic corrections – which can hardly be compared to more serious surgeries that require more pain relief and days or weeks of recovery, not just 6 to 12 hours.      

Another issue is the use of codeine as a research subject. Stefan Franzen, PhD, a chemistry professor at North Carolina State who has an extensive background in biomedical research, questions whether low doses of codeine should even be compared to NSAIDs.

“I question the premise that codeine is the drug that is or should be used by dentists,” said Franzen, author of “Patient Z,” a book the examines the criminalization of pain care. “I read a few papers not cited by this report and they too do not find a great efficacy for codeine. Part of this may be dose. Most commonly they are using 30-60 mg of codeine, which is 5-10 mg of morphine. Not very much if you have severe pain.

“Codeine may be a poor choice, but it may also be a straw man. Why not use tramadol, for example?”

‘Manipulated Data’

Patient advocate Bill Murphy also has doubts about the selection criteria used in studies touting the benefits of non-opioid pain relievers. He believes some researchers cherry-pick evidence to support a conclusion they’ve already reached.

“Opioid sparing post-op surgery programs are nothing more than an attempt to solve a non-problem and in doing so, patients suffer needlessly. The data produced from such programs are very often manipulated by those who designed the program in an obvious attempt to skew the results in favor of a program they endorsed,” said Murphy, who helped get legislation passed in New Hampshire to ensure that pain patients have access to opioid medication.

Murphy has advocated on behalf of patients at Portsmouth Regional Hospital, which has an “Enhanced Surgical Recovery” program that significantly reduced the use of opioids. Instead of Vicodin, patients get Neurontin or nerve blocks for pain relief.

“I was personally called in to advocate on behalf of several patients who were left to suffer in pain following surgery only to have staff assure them their pain was being well managed,” Murphy explained in an email. “Surgeons and nurses reported they were doing very well with Portsmouth Regional’s new protocol for managing post-op pain when in fact, they were not doing ‘very well’ at all.

“These patients were in horrible pain. Of the three I spoke with, none were ever provided any relief. I was with one patient as she was discharged. She was in tears and moved at a glacial pace due to pain as her son and I helped her into his vehicle outside. It was heartbreaking to watch. Her adult son was furious. I stayed in touch with each patient for several weeks afterwards. Each suffered greatly, one was not making any gains in physical therapy due to her lasting pain.”

In 2019, only 11% of patients were prescribed an opioid while at the Portsmouth hospital, and less than 6% were discharged with an opioid prescription. Murphy says the hospital’s policy inevitably leads to some patients with poorly treated pain.  

“What Portsmouth Regional Hospital’s ‘Enhanced Surgical Recovery’ program was doing is akin to making patients bite down on a piece of wood, grind it out, and then convince them the whole experience was for their own good,” says Murphy.    

Doctors Required to Provide Patient Health Records at No Cost and On Demand

By Sarah Kwon, Kaiser Health News

A new federal regulation makes it easy to get test results and see what your doctor is recording about your health. One downside: You might not understand what you read.

Last summer, Anna Ramsey suffered a flare-up of juvenile dermatomyositis, a rare autoimmune condition, posing a terrifying prospect for the Los Angeles resident: She might have to undergo chemotherapy, further compromising her immune system during a pandemic.

After an agonizing three-day wait, the results of a blood test came back in her online patient portal — but she didn’t understand them. As hours passed, Ramsey bit her nails and paced. The next day, she gave in and emailed her doctor, who responded with an explanation and a plan.

For Ramsey, now 24, instant access to her test results had been a mixed blessing. “If there’s something I’m really nervous about,” she said, “then I want interpretations and answers with the result. Even if it takes a few days longer.”

On April 5, a federal rule went into effect that requires health care providers to give patients like Ramsey electronic access to their health information without delay upon request, at no cost. Many patients may now find their doctors’ clinical notes, test results and other medical data posted to their electronic portal as soon as they are available.

Advocates herald the rule as a long-awaited opportunity for patients to control their data and health.

“This levels the playing field,” said Jan Walker, co-founder of OpenNotes, a group that has pushed for providers to share notes with patients. “A decade ago, the medical record belonged to the physician.”

But the rollout of the rule has hit bumps, as doctors learn that patients might see information before they do. Like Ramsey, some patients have felt distressed when seeing test results dropped into their portal without a physician’s explanation. And doctors’ groups say they are confused and concerned about whether the notes of adolescent patients who don’t want their parents to see sensitive information can be exempt — or if they will have to breach their patients’ trust.

Barriers Removed

Patients have long had a legal right to their medical records but often have had to pay fees, wait weeks or sift through reams of paper to see them.

The rule aims not only to remove these barriers, but also to enable patients to access their health records through smartphone apps, and prevent health care providers from withholding information from other providers and health IT companies when a patient wants it to be shared.

Privacy rules under the Health Insurance Portability and Accountability Act, which limit sharing of personal health information outside a clinic, remain in place, although privacy advocates have warned that patients who choose to share their data with consumer apps will put their data at risk.

Studies have shown numerous benefits of note sharing. Patients who read their notes understand more about their health, better remember their treatment plan and are more likely to stick to their medication regimen. Non-white, older or less educated patients report even greater benefits than others.

For Sarah Ford, 34, of Pittsburgh, who has multiple sclerosis, reading her doctor’s notes helps her make the most of each visit and feel informed.

“I don’t like going into the office and feeling like I don’t know what’s going to happen,” she said. If she wants to try a new medication or treatment, reading previous notes helps her prepare to discuss it with her doctor, she said.

The new rule will have less impact on Ford and the more than 50 million patients in the U.S. whose doctors had already made their notes available to patients before the rule kicked in. However, only about a third of patients with access to secure online health portals were using them.

While most doctors who have shared notes with patients think it’s a good idea, the policy has drawbacks. One recent study found that half of doctors reported writing their notes less candidly after they were opened to patients.

Another study, published in February, found that 1 in 10 patients had ever felt offended or judged after reading a note. The study’s lead author, Dr. Leonor Fernandez, of Beth Israel Deaconess Medical Center, said there is a “legacy of certain ways of expressing things in medicine that didn’t really take into account how it reads when you’re a patient.”

“Maybe we can rethink some of these,” she said, citing the phrase “patient admits to drinking two glasses of wine a day” as an example. “Why not just write ‘two glasses of wine a day’?”

UC San Diego Health started phasing in open notes to patients in 2018 and removed a delay in the release of lab results last year. Overall, said Dr. Brian Clay, chief medical information officer, both have been uneventful. “Most patients are agnostic, some are super-jazzed, and a few are distressed or have lots of questions and are communicating with us a lot,” he said.

Some Records Withheld

There are exceptions to the requirement to release patient data, such as psychotherapy notes and notes that could harm a patient or someone else if released.

Dr. David Bell, president of the Society for Adolescent Health and Medicine, believes it’s unclear exactly what qualifies as “substantial harm” to a patient — the standard that must be met for doctors to withhold an adolescent patient’s notes from a parent. Clarity, he said, is especially important to protect teenagers living in states with less restrictive laws on parental access to medical records.

Most electronic medical records are not equipped to segregate sensitive pieces from other information that might be useful for a parent in managing their child’s health, he added.

Some doctors say receiving devastating test results without counseling can traumatize patients. Dr. James Kenealy, an ear, nose and throat doctor in central Massachusetts, said a positive cancer biopsy result for one of his patients was automatically pushed to his portal over the weekend, blindsiding both. “You can give bad news, but if you have a plan and explain, they’re much better off,” he said.

Such incidents aren’t affecting the majority of patients, but they’re not rare, said Dr. Jack Resneck Jr., an American Medical Association board trustee. The AMA is advocating for “tweaks” to the rule, he said, like allowing brief delays in releasing results for a few of the highest-stakes tests, like those diagnosing cancer, and more clarity on whether the harm exception applies to adolescent patients who might face emotional distress if their doctor breached their trust by sharing sensitive information with their parents.

The Office of the National Coordinator for Health Information Technology, the federal agency overseeing the rule, responded in an email that it has heard these concerns, but has also heard from clinicians that patients value receiving this information in a timely fashion, and that patients can decide whether they want to look at results once they receive them or wait until they can review them with their doctor. It added that the rule does not require giving parents access to protected health information if they did not already have that right under HIPAA.

Patient advocate Cynthia Fisher believes there should be no exceptions to immediately releasing results, noting that many patients want and need test results as soon as possible, and that delays can lead to worse health outcomes. Instead of facing long wait times to discuss diagnoses with their doctors, she said, patients can now take their results elsewhere. “We can’t assume the consumer is ignorant and unresourceful,” she said.

In the meantime, hospitals and doctors are finding ways to adapt, and their tactics could have lasting implications for patient knowledge and physician workload. At Massachusetts General Hospital, a guide for patients on how to interpret medical terminology in radiology reports is being developed, said Dr. William Mehan, a neuroradiologist.

An internal survey run after radiology results became immediately available to patients found that some doctors were monitoring their inbox after hours in case results arrived. “Burnout has come up in this conversation,” Mehan said.

Some electronic health records enable doctors to withhold test results at the time they are ordered, said Jodi Daniel, a partner at the law firm Crowell & Moring. Doctors who can do this could ask patients whether they want their results released immediately or if they want their doctor to communicate the result, assuming they meet certain criteria for exceptions under the rule, she said.

Chantal Worzala, a health technology policy consultant, said more is to come. “There will be a lot more conversation about the tools that individuals want and need in order to access and understand their health information,” she said.

Americans Reporting More Chronic Pain

By Pat Anson, PNN Editor

A startling new study has concluded that the prevalence of chronic pain has grown substantially in the United States since 2002, affecting virtually every age group, sex, ethnicity and demographic. By 2018, over half of American adults (54%) reported having pain, with each birth group in greater pain than the one that came before it.

“You might think that with medical advances we’d be getting healthier and experiencing less pain, but the data strongly suggest the exact opposite,” said co-author Hanna Grol-Prokopczyk, PhD, an associate professor of sociology in the University at Buffalo College of Arts and Sciences.

“We looked at the data from every available perspective including age, gender, race, ethnicity, education, and income, but the results were always the same: There was an increase in pain no matter how we classified the population.”

Grol-Prokopczyk and her colleagues analyzed responses from over 441,000 people who participated in the National Health Interview Survey (NHIS) from 2002 to 2018. While research on pain trends usually focuses on people over age 50, they look at adults aged 25-84. The data was analyzed for reports of joint, low back, neck, face or jaw pain, along with headaches and migraines.

The research findings, published in the journal Demography, show that pain increased for each body site during the study period, especially for joint, low back and neck pain. Reports of pain in at least one site increased by 10%, representing an additional 10.5 million adults experiencing pain.

SOURCE: DEMOGRAPHY

Not surprisingly, pain was most common in the oldest age group (65-84), with health problems such as high body mass index (BMI), hypertension, diabetes and kidney conditions correlating with increases in pain. Obesity was also associated with more pain in young and middle-aged adults, along with more stress and alcohol consumption.

“What we’re seeing in the younger age groups demonstrates how pain in some ways functions as much as a mental health problem as it does a physical health problem,” said Grol-Prokopczyk. “Pain can be exacerbated by stress, and stress can bring about alcohol use.”

Socioeconomic disparities are also involved. While pain increased for people in every income and education level, it rose faster for low-income Americans and those who never attended college.

“This study has documented steep, sustained, and pervasive increases in chronic pain among Americans across the adult life span. This is a concerning finding that should stimulate new research in demography and other social sciences. We found that key correlates of the rise in pain prevalence include not only specific diagnoses, such as arthritis, but also psychological distress, increased body weight, and heavier alcohol use -- factors that highlight the psychosocial roots of pain in populations,” researchers concluded.

Are Americans experiencing more pain or just reporting it more often? And what role, if any, did the opioid crisis play? The researchers found no definitive answers to either question, but they speculated that increased opioid use and awareness about pain may have led Americans to report pain more readily in the hope of getting it treated.

“Our findings in this study are not an argument for increased opioid use; in contrast, we posit that opioids may have contributed to the rise of pain prevalence in the United States,” they said.

That statement is puzzling, because opioid prescribing peaked in 2011 and has steadily declined ever since. The researchers apparently did not consider that more pain is being reported because it is often poorly treated or untreated.

A recent PNN survey of nearly 3,700 patients found that over 92% believe their pain levels and quality of life have grown worse. Over a third said they were unable to find a doctor to treat their pain and 58% said they were taken off opioids or tapered to a lower dose against their wishes.  

Chronic Pain Linked to Memory Loss in Some Older Adults

By Pat Anson, PNN Editor

A new study suggests that people who live with chronic pain may be at higher risk of memory loss and cognitive decline if they have lower levels of education, income and access to healthcare.

The study by researchers at the University of Florida, published in the Journal of Alzheimer’s Disease, involved 147 adults between the ages of 45 and 85 who had mild to moderate knee pain. Participants enrolled in the study were asked to provide sociodemographic information, complete an assessment of their cognitive function, and have MRI brain scans.

People with higher pain levels who had low levels of income and education, and less access to health insurance had about 4% less gray matter in the temporal lobe of their brains (the area shaded in blue) compared to people with low pain levels who had more income and education, and greater access to healthcare.

“As we get older, typically starting around our mid-50s to mid-60s, we lose about half a percent of our gray matter per year,” said lead author Jared Tanner, PhD, an assistant professor of clinical and health psychology in the UF College of Public Health and Health Professions. “So a 3-4% difference could be thought of as an additional six to eight years of aging in the brain.”

The thinning of gray matter is predictive of future cognitive decline and greater risk of developing dementia or Alzheimer’s disease.

Tanner and his colleagues have been investigating how chronic pain acts as a stressor that causes physiological changes in humans. Other researchers have found that Black adults are up to twice as likely as White adults to develop Alzheimer’s disease. The new findings indicate a variety of environmental factors might be involved, including access to healthcare.

“This study helps us begin to identify an additional factor to explore that may contribute to health disparities in rates of dementia and Alzheimer’s disease in some underrepresented ethnic/race groups. In this case, it looks like stage of chronic pain, along with other life experiences, may be playing a role,” said Tanner.

“The body and the brain are adaptive to stress to a certain point,” said senior author Kimberly Sibille, PhD, an associate professor of aging & geriatric research and pain medicine in the UF College of Medicine. “But with persistent stressors that are more intense and longer duration, eventually the body’s response is no longer adaptive and changes start occurring in the other direction, a process known as allostatic overload. 

“People with low pain stage — intermittent, low intensity, shorter duration and minimal sites of pain — differ from the groups with higher stages of chronic pain. Further, in combination with lower protective factors, including lower income, education and health insurance access, those individuals with higher chronic pain stage show less gray matter in cortical areas of the brain.”

A large 2017 study found that people aged 60 and older with chronic pain had faster declines in memory and cognitive ability than those who were not troubled by pain.

The brain may be able to regain some of its ability to function normally. A 2009 study of osteoarthritis patients showed a reversal in brain changes when their pain was adequately treated. 

Ideology Is Guiding Pain Care, Not Science

By Roger Chriss, PNN Columnist

An overarching question in pain management and the opioid crisis is whether or not prescription opioids have any value in treating chronic non-cancer pain. 

Some say that the answer is a resounding “No.” Studies to date on the effectiveness of opioids are often too small, methodologically weak or too short-term to be convincing. But these same studies are often used to claim lack of efficacy, and for the same reasons they cannot do that.

At present, we don’t know if or how well opioids work for chronic pain. To establish efficacy, we’d need major studies or clinical trials that run for years, using many hundreds or even thousands of patients. Opioids would need to be compared to placebo or other treatments for various forms of chronic non-cancer pain, from inflammatory and autoimmune conditions to neuropathies and genetic disorders.

Such studies have not been done. A U.S. government website that tracks clinical studies lists 685 trials for “opioids and chronic pain,” with several terminated or withdrawn, others just now recruiting, and only a handful completed. Many of these studies look at substance use disorders, tapering or de-prescribing, or are small-scale efforts at comparing two opioids.

There are no large-scale studies of opioids for chronic non-cancer pain getting started or underway at present.

There are over 14,500 studies on “opioids and chronic pain” listed in PubMed, a database maintained by the National Institutes of Health. One of the few that looked at long-term use of opioids is the 2018 SPACE study, which found that opioids were not superior to non-opioid medications over 12 months.

But the SPACE study has important limitations: It only looked at patients with chronic back pain or osteoarthritis of the hip and knee. Researchers also put the opioid tramadol in the non-opioid group and let some patients switch from the non-opioid to the opioid arm in order to achieve good analgesia.

Another study found that only one in five patients benefited from long-term opioid therapy, with young and middle-aged women showing the least improvement in pain and function. But this was a telephone survey that relied on a pain scale to assess outcomes, with no mention of diagnoses and no randomization or placebo control.

Similar studies with more positive outcomes can be found. According to a Cochrane review, the opioid tapentadol (Nucynta) worked better than oxycodone and a placebo in treating chronic musculoskeletal pain. But the clinical significance of this finding is uncertain.

In other words, we don’t have the kinds of studies we need to figure out if opioids work for chronic pain. This means that when people claim there is no good evidence for opioids in long-term pain management, they have a point. But for the same reason, there is no good evidence against opioid efficacy, either.

Of course, there is good evidence about opioid risks. As PNN reported, an Australian study found that people on long-term opioids do sometimes engage in risky behavior such as filling a prescription early. But this study didn’t find major risks of dose escalation, diversion or overdose that are often claimed to be common.

The solution would be to do major trials. But there seems to be little incentive to do this. The opioid crisis and associated ideological debate about drug legalization have combined with lawsuits and public health policy to remove any motivation to find out more about efficacy. The results of such a study could sway outcomes in the ongoing opioid litigation or ignite new lawsuits, or could even cripple advocacy groups on either side of the opioid divide.

There are, arguably, subtle incentives not to pursue high-quality clinical trials on opioids for long-term pain management. Instead, we’re seeing lots of meta-analyses, reviews, and retrospective studies, none of which is particularly convincing because summarizing old studies with known weaknesses generally cannot answer big questions.

For the foreseeable future, we may be stuck with ideology instead of science guiding clinical pain care.

Genetics May Explain Why Women Are More Likely to Have Chronic Pain

By Pat Anson, PNN Editor

It’s no secret that women are far more likely than men to experience fibromyalgia, migraine, osteoarthritis and other chronic pain conditions. Why that is has been linked to everything from gender bias in healthcare to childhood trauma to women “catastrophizing” about their pain.  

A new study published by UK researchers in PLOS Genetics suggests that part of the reason is genetic differences between men and women.

In the largest genetic study of its kind, researchers at the University of Glasgow looked for genetic variants associated with chronic pain in over 209,000 women and 178,000 men who donated their medical and genetic data to the UK Biobank.

The researchers also investigated whether the activity of those genes was turned up or down in tissues commonly involved with chronic pain.

They found that 37 genes in men and 30 genes in women were active in the dorsal root ganglion, a cluster of nerves in the spinal cord that transmit pain signals from the body to the brain.

The findings support previous work by the same research team, which found that chronic pain originates to a large extent in the brain, and to a lesser degree in parts of the body where people “feel” pain. The study also suggests genetic differences between men and women may affect the immune system and how the two sexes respond to medication.

“Overall, our findings indicate the existence of potential sex differences in chronic pain at multiple levels… and the results support theories of strong nervous system and immune involvement in chronic pain in both sexes,” wrote lead author Keira Johnston of the University of Glasgow. "Our study highlights the importance of considering sex as a biological variable and showed subtle but interesting sex differences in the genetics of chronic pain."

Gender Bias

While genetic differences may partially explain why women are more likely to feel pain than men, gender biases may explain why they are treated differently, according to another study recently published in the Journal of Pain.

Researchers at the University of Miami found that when volunteers observed male and female patients expressing the same amount of pain, they had a tendency to view female patients' pain as less intense and more likely to benefit from psychotherapy.

The study consisted of two experiments in which adult volunteers were asked to view videos of men and women who suffered from shoulder pain. The videos came from a database of real patients experiencing different degrees of pain, and included their self-reported pain levels when moving their shoulders in a series of exercises.

The volunteer observers were asked to gauge the amount of pain they thought the patients in the videos experienced. They were also asked how much pain medication and psychotherapy they would prescribe to each patient, and which of the treatments they thought would be more effective.

The study found that female patients were perceived to be in less pain than the male patients — even when they reported and exhibited the same pain levels. Researchers believe those perceptions were partially explained by gender-based stereotypes.

"If the stereotype is to think women are more expressive than men, perhaps 'overly' expressive, then the tendency will be to discount women's pain behaviors," said co-author Elizabeth Losin, PhD, assistant professor of psychology at the University of Miami.

"The flip side of this stereotype is that men are perceived to be stoic, so when a man makes an intense pain facial expression, you think, 'Oh my, he must be dying!' The result of this gender stereotype about pain expression is that each unit of increased pain expression from a man is thought to represent a higher increase in his pain experience than that same increase in pain expression by a woman."

The volunteer observers were also more likely to choose psychotherapy as a treatment than pain medication for the female patients.

Interestingly, the gender of the observers did not influence pain estimation. Both men and women interpreted women's pain to be less intense.

"I think one critical piece of information that could be conveyed in medical curricula is that people, even those with medical training in other studies, have been found to have consistent demographic biases in how they assess the pain of male and female patients and that these biases impact treatment decisions," said Losin.

"Critically, our results demonstrate that these gender biases are not necessarily accurate. Women are not necessarily more expressive than men, and thus their pain expression should not be discounted."

Study Finds Placebos Disrupt Pain Signals in Brain

By Pat Anson, PNN Editor

Much of the pain relief that a person gets from taking an analgesic medication is due to individual mindset, not the drug itself, according to new research that looks at how the human brain responds to a placebo.

The placebo effect is a well-documented but poorly understood condition in which a patient responds to a drug or treatment that is designed to have no therapeutic value. A 2018 study, for example, found that about half of patients who took a sugar pill they thought was an analgesic had a 30% reduction in pain – a level considered effective for an actual painkiller.    

To better understand how that is possible, researchers at Dartmouth University conducted a meta-analysis of 20 neuroimaging studies involving 603 healthy people who participated in placebo studies. Their findings, recently published in Nature Communications, showed that placebo treatments reduced pain-related activity in multiple areas of the brain.

"Our findings demonstrate that the participants who showed the most pain reduction with the placebo also showed the largest reductions in brain areas associated with pain construction," explains co-author Tor Wager, PhD, a Neuroscience Professor who is principal investigator of the Cognitive and Affective Neuroscience Lab at Dartmouth.

"We are still learning how the brain constructs pain experiences, but we know it's a mix of brain areas that process input from the body and those involved in motivation and decision-making. Placebo treatment reduced activity in areas involved in early pain signaling from the body, as well as motivational circuits not tied specifically to pain."

By examining brain images, researchers were able to identify the placebo effect in regions of the brain that process pain signals (nociception) and generate pain sensations.

They found that placebos strongly affect the thalamus, which processes sights, sounds and other types of sensory input; as well as the basal ganglia, which is important for motivation and pain-related activities.

Placebo treatments also reduced activity in the brain’s posterior insula, which is one of the areas involved in creating pain sensations. This suggests that placebos change the pathway for how pain is processed in the brain. 

"The placebo can affect what you do with the pain and how it motivates you, which could be a larger part of what's happening here," says Wager. "It's changing the circuitry that's important for motivation."

Previous research has found that placebos activate the brain’s prefrontal cortex, which triggers the release of natural, pain-relieving hormones that can block pain signals from being processed.

Researchers say placebo effects likely involve a combination of different brain reactions, depending on the placebo and people's predispositions. In other words, there is no uniformity in the placebo response because everyone is different.

"Our results suggest that placebo effects are not restricted solely to either sensory/nociceptive or cognitive/affective processes, but likely involves a combination of mechanisms that may differ depending on the placebo paradigm and other individual factors," said co-author Ulrike Bingel, PhD, a professor at the Center for Translational Neuro- and Behavioral Sciences at University Hospital Essen.

A 2016 study that looked at brain images of osteoarthritis patients found that about half had mid-frontal brain regions that had more connectivity with other parts of the brain, making them more likely to respond to the placebo effect. That could help could explain why some respond well to pain medication, while others do not.
