ME/CFS Research Published 19-25 April 2022

The weekly research round-up includes recent publications about ME/CFS and Long Covid. We highlight the studies that have particularly caught our interest and follow these with the full list of publications together with their abstracts (summaries).

All research relating to ME/CFS can be located in the ME Association: Index of ME/CFS Published Research. It is a FREE resource, available to anyone, and updated at the beginning of each month.

The Index provides an A-Z of published research studies, selected key documents and articles, listed by subject matter, on myalgic encephalomyelitis, myalgic encephalopathy, and/or chronic fatigue syndrome (ME/CFS).

You can use it to easily locate and read any research that you might be interested in regard to, e.g., epidemiology, infection, neurology, post-exertional malaise etc.

You can also find the Research Index in the Research section of the website together with a list of Research Summaries that provide more detailed lay explanations of the more interesting work that has been published to date.

ME/CFS Research Published 19 – 25 April 2022 

I’ve been doing this role for almost a year now, and this is the first time I have reported no new ME/CFS studies, however, there have been sixteen studies on Long Covid.  

None of the Long Covid studies particularly caught our eyes, with most studies focusing on describing symptoms and clinical features. We briefly highlight two of the studies below: 

Paper one (1) is on developing an exercise training programme for Long Covid. The study reviewed pervious published exercise protocols to build a new tailored approach. 

The studies focused on the use of exercise training due to the benefits seen for cardiac or lung disease patients as well as benefitting the immune system and inflammation. However, this does not take into account the strong clinical similarities with ME/CFS and the damaging effects of exercise. 

Dr Charles Shephard has provided a comment for this study: 

“It is very disturbing to see that this research group is advocating an ‘exercise training' programme for people with Long Covid but do not appear to have any knowledge or understanding of the very important clinical and pathological overlaps between ME/CFS and Long Covid, especially the need to avoid post-exertional malaise/symptom exacerbation when advising on activity and energy management.  

The dangers of over-simplistic exercise regimes have been known to people with ME/CFS (and to many health professionals) for many years and the new NICE guideline clearly states that they can no longer be recommended for people with ME/CFS. 

I hope that the same serious mistakes that have made with ME/CFS and GET programmes are not now going to be repeated for people with Long Covid.” 

Paper four (4) is on the use of vitamin D for long covid. The paper highlights the huge range of benefits in taking vitamin D and its fundamental role in immune system function. Current evidence shows that vitamin D can reduce the risk of covid-19, for example: inactivates the virus, anti-viral effects, promotes adaptive immunity, neuroprotection and reduces risk of cytokine storm (an aggressive inflammatory response due to too many cytokines being released at once, which is harmful).  

There is currently not enough evidence to show that vitamin D effects symptoms or biomarkers, but the authors conclude that it is an inexpensive and safe supplement to take as part of Long Covid treatment. Some research has also suggested that vitamin D could have a role to play in treatment of ME/CFS, however, evidence is still lacking. The ME Association has a leaflet on this, as well as more information here. (NB- Use of vitamin D supplementation should be under medical supervision.
