Rare Disease Spotlight: Asplenia
/By Barby Ingle, PNN Columnist
If you have been following my series on rare diseases or read any of my books, you already know that I live with multiple rare diseases.
I was fortunate to live to the age of 29 before developing any symptoms. Others are not as lucky. There are over 7,000 rare diseases, and I find that the ones that catch my attention the most are those that affect infants and young people, such as asplenia and Alexander disease.
One of the people I met while advocating for chronic and rare diseases in Arizona is Allison. Her son Travis passed away at the age of four due to complications of asplenia. In his memory, she started a nonprofit called TEAM 4 Travis.
Allison’s son was a bright, smiling little boy who was born without a functional spleen, an organ that helps filter the blood as part of the immune system. That is what asplenia means; the absence of a spleen. If Travis had been checked during newborn screening, he might still be alive today.
My stepsister Melanie lost her spleen in an auto accident at the age of six, but was able to live into her early thirties. She passed away due to complications of one of the same rare conditions that I have, Reflex Sympathetic Dystrophy (RSD).
TRAVIS AND ALLISON
Those who have had a splenectomy (Melanie) or are born with missing or nonfunctional spleen (Travis) are immunocompromised, which puts them at increased risk for severe and overwhelming bacterial infections, particularly from encapsulated bacteria.
Melanie's doctors knew she no longer had a spleen, so she was able to take medications that took on the role of a spleen. Travis was not so fortunate and lost his life due to an infection. It was only discovered after he passed away that he had asplenia.
Every time I go with Alison to talk to our legislators and hear the story of Travis, it gets me emotionally because this is a loss that could be prevented. That is why we advocate for newborn screenings in Arizona and other states.
Alexander Disease
The other spotlight I wanted to shine this month on a rare disease that affects children is Alexander disease. There is not a lot of talk about this condition or how it affects a family on a personal level. I can imagine that it would be quite difficult to lose your child to a neurodegenerative condition.
Alexander disease is a genetic disorder that primarily affects infants and young children. If symptoms begin before the age of two, chances are the child will pass before their sixth birthday. In cases of adult and juvenile-onset, one can live and manage Alexander disease longer. However, as with RSD, infants, youths and adults have different symptoms, onsets and challenges.
An infant with Alexander disease will show symptoms like an enlarged brain and/or head size. They may also have seizures, dystonia, and developmental delays that are easy to spot by providers and parents.
In adult-onset Alexander disease, symptoms can be fluid. The brain may show signs of swelling, but it will come and go, causing atrophy over time. Doctors will see lesions in the brain stem and upper spinal cord under contrast enhancements. When earlier stages of the disease are not treated, it can lead to vocal cord paralysis.
You can learn more Alexander disease and asplenia by visiting the National Institutes of Health. There are also clinical trials developing new treatments for both of these conditions.
If you need support for Alexander disease as a patient or caregiver, you can turn to the United Leukodystrophy Foundation. If you need support for asplenia, please check out Allison’s TEAM 4 Travis Foundation.
