COVID-19 and chronic fatigue syndrome: Is the worst yet to come? by Peter Wostyn in Med Hypotheses 2021 Jan 2 [doi: 10.1016/j.mehy.2020.110469]
Article abstract:
There has been concern about possible long-term sequelae resembling myalgic encephalomyelitis/chronic fatigue syndrome in COVID-19 patients. Clarifying the mechanisms underlying such a “post-COVID-19 fatigue syndrome” is essential for the development of preventive and early treatment methods for this syndrome.
In the present paper, by integrating insights pertaining to the glymphatic system and the nasal cerebrospinal fluid outflow pathway with findings in patients with chronic fatigue syndrome, idiopathic intracranial hypertension, and COVID-19, I provide a coherent conceptual framework for understanding the pathophysiology of post-COVID-19 fatigue syndrome.
According to this hypothesis, this syndrome may result from damage to olfactory sensory neurons, causing reduced outflow of cerebrospinal fluid through the cribriform plate, and further leading to congestion of the glymphatic system with subsequent toxic build-up within the central nervous system. I further postulate that patients with post-COVID-19 fatigue syndrome may benefit from cerebrospinal fluid drainage by restoring glymphatic transport and waste removal from the brain.
Obviously, further research is required to provide further evidence for the presence of this post-viral syndrome, and to provide additional insight regarding the relative contribution of the glymphatic-lymphatic system to it. Other mechanisms may also be involved. If confirmed, the glymphatic-lymphatic system could represent a target in combating post-COVID-19 fatigue syndrome.
Moreover, further research in this area could also provide new insights into the understanding of chronic fatigue syndrome.

To explore the impacts that Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has on the patient and their family members using the WHOQOL-BREF (Abbreviated World Health Organisation Quality of Life questionnaire) and FROM-16 (Family Reported Outcome Measure-16) quality of life assessments.
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic, disabling, and complex multisystem illness of unknown etiology. The
The diagnosis of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is problematic due to the lack of established objective measurements. Post-exertional malaise (PEM) is a hallmark of ME/CFS, and the two-day cardiopulmonary exercise test (CPET) has been tested as a tool to assess functional impairment in ME/CFS patients. This study aimed to estimate the potential of the CPET.
A manifesto at least
Sandra had severe ME for 20 years and associated chemical sensitivity for the last 10, which made it difficult for her to visit buildings to discuss her medical or social care needs. Even ambulances were a difficult environment for her and her health had been deteriorating for some time. She suffered a lot of misunderstanding and dismissal over the years from people whose job it was to help her. In spite of this she fought hard to explain severe ME to them. She contributed her experiences to the Hywel Dda ME stakeholder group, although it cost her a lot.



There was much in the guideline to be pleased about and we are grateful to those on the guideline committee, and to those who supplied evidence to the committee. The guideline included annexes and was accompanied by 13 other documents, so there was a lot to read and absorb in the 6 week consultation period! Inevitably we will not have picked up all the issues that needed to be addressed, but hopefully, in combination with other patient groups’ responses, our comments will have represented people in Wales and will make a difference.
