Long before the term “long COVID” entered the public lexicon, Sanna Stella encountered firsthand how a common respiratory infection can transform into a persistent health condition.
Back in 2014, a bout of bronchitis left Stella, a therapist residing in the Chicago region, grappling with overwhelming fatigue.
Within a mere month, her mobility was severely restricted, making a simple walk from the sofa to the kitchen table a daunting task. Eventually, Stella was diagnosed with chronic fatigue syndrome, now known as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
Individuals with this condition can experience a variety of symptoms, including extreme tiredness, cognitive difficulties, and post-exertional malaise, a worsening of symptoms after physical activity. Despite affecting over 4 million Americans, there is currently no FDA-approved treatment for ME/CFS.
Receiving an official diagnosis did not significantly alter Stella’s daily struggles. “I felt frustrated and helpless, knowing that I would be confined to bed without any viable solutions,” she recounts.
Determined to contribute to the understanding of this illness, Stella eagerly participated in a comprehensive study spearheaded by the National Institutes of Health, fully aware of the toll it would take on her body.
“The entire experience was incredibly challenging,” she admits. “After the initial few days, I could only manage to attend testing sessions on a stretcher, but my primary goal was to aid in advancing research efforts.”
After seven years, the findings of the study were finally published in Nature Communications this week. The research offers a comprehensive examination of the biological irregularities associated with ME/CFS, encompassing the brain, gut, immune system, and autonomic nervous system.
Exploring Chronic Fatigue Syndrome Clues
According to senior author Dr. Avindra Nath, clinical director of the National Institute of Neurological Disorders and Stroke, the symptoms cannot be attributed to physical deconditioning or psychological factors. He emphasizes the presence of true biological differences.
The study’s findings align with existing knowledge in the field. However, the comprehensive examination of the illness sets it apart, potentially paving the way for new treatment avenues.
Dr. Nancy Klimas, from the Institute for Neuro-Immune Medicine at Nova Southeastern University, describes the evaluation as the most thorough she has encountered in a clinical setting.
Despite being hindered by the COVID-19 pandemic, which affected its timeline and participant numbers, the study, initiated in 2016, included only 17 ME/CFS patients in the end.
The overlap in symptoms between ME/CFS and long COVID might actually draw more attention to the study’s findings than it would have received otherwise.
**Chronic Fatigue Syndrome Clues**
The exact cause of ME/CFS remains uncertain, although several theories exist. Many instances, though not all, appear to emerge following a recent infection, such as the Epstein-Barr Virus or other pathogens. Research on this condition was neglected for years, dismissed as “purely psychological.” Even now, there are only a few ongoing clinical trials, according to Maureen Hanson, a molecular biology and genetics professor at Cornell University.
Enhancing Understanding of the Immune System’s Battle
The extensive NIH Intramural study, involving over 75 scientists and costing millions, meticulously selected participants from a pool of 200 patients. This ensured accurate diagnoses linked to infections, alongside comprehensive psychological and medical assessments.
Enrolled individuals spent weeks at the NIH Clinical Center in Bethesda, Maryland, undergoing various tests, including muscle biopsies and time in controlled metabolic chambers.
The study’s authors suggest that Chronic Fatigue Syndrome (CFS) is primarily a brain disorder, likely triggered by immune dysfunction and alterations in the gut microbiome. Dr. Anthony Komaroff from Harvard Medical School supports these findings, aligning with existing research.
The research presents compelling evidence that the immune system remains chronically activated, akin to a prolonged battle against a foreign microbe. This perpetual struggle indicates that a remnant antigen from an infection continues to disrupt the immune system, leading to a cascade of physiological events culminating in symptoms.
This theory expands on previous work by researchers like Hanson, who identified T cell dysfunction or “exhaustion” resulting from continuous exposure to the same antigen. When T cells become exhausted, their ability to combat pathogens diminishes, a significant consequence of chronic infections.
While this theory gains support for both CFS and long COVID, other possibilities exist. It is plausible that infections trigger autoimmune responses or provoke immune system complications through alternative mechanisms.
Considering these factors, it is conceivable that a combination of these scenarios contributes to the development of CFS and related conditions.
