ME/CFS Science Profile picture

1) There’s a new interesting study out by a collaboration of ME/CFS patients and scientists.

They’ve sent Freedom of Information requests to 38 NHS specialist centers for ME/CFS and asked them about their information on harms by rehabilitative therapies such as GET or CBT.
2) The results are striking. Among the ME/CFS clinics surveyed, there was an almost universal absence of criteria for detecting harm, and no clinic reported any harm to have occurred in their patients, despite acknowledging that many dropped out of treatment.
3) No clinic reported telling patients explicitly that they could be worse after therapy than before. They only said that setbacks were possible (but temporary) or that the reported harms of GET are due to the treatment being wrongly executed.
4) So patients getting worse during treatment might think that their decline is due to something else.

The authors suggest this can result in a “misinformation loop”: the clinics say GET is safe, patients believe that and do not report harm, clinics think GET is really safe...
5) Or as the authors put it more eloquently: “if clinics presume that treatments are harmless, they will inevitably fail to record harms accurately.”

Another possibility is of course that patients do report harms but that clinics do not use or record this information.
6) The solution the authors propose is a national system for collecting information from patients who think they have been harmed by rehabilitative therapies such as GET, something similar to the Yellow Card Scheme for adverse effects arising from medical drugs or devices.
7) The study was published in The Journal of Health Psychology and can be found here: journals.sagepub.com/doi/abs/10.117…

1) Suppose this isn't a coincidence:

- Olfactomedin 4 (OLFM4) Is a Biomarker for the severity of infectious diseases.

- OLFM4 is also one of the few DecodeME hits for patients with an infectious onset. Image
2) OLFM4 is expressed in gut epithelial cells and is stored in the granules of neutrophils, the most common type of white blood cells.

These granules are like storage spaces that contain enzymes, and antimicrobial molecules that neutrophils release during infection.
3) Interestingly, OLFM4 isn't an inflammatory protein. It reduces the antibacterial and inflammatory responses of neutrophils.

It does so by binding to the neutrophils cationic proteins and neutralizing their ability to kill bacteria and form immunogenic complexes with DNA.

1) Very preliminary data but Dutch researchers report that antibodies of Long Covid patients caused more cultured muscles cells to die. Image
2) This comes from the research group of Jeroen Den Dunnen, whose preprint showed that transfer of antibodies (IgG) from Long COVID patients induces symptoms in mice.

Similar findings were reported by the group of Iwasaki and a Belgian team from Namur. Image
3) They are exploring a connection with their autoantibody results and the muscle abnormalities and necrosis that the team of Rob Wust found in Long Covid patients.

1) Interesting presentation by Anouk Slaghekke at the 2025 Berlin conference.

This Dutch team found that small blood vessels of patients with ME/CFS and Long Covid are clocked up with Collagen IV. Image
2) They zoomed in on the muscle capillaries, the tiny blood vessels that are so small that red blood cells need to move through them one by one.
3) The Dutch researchers found that the basement membrane was thicker in patients.

This is the supportive layer of proteins around the capillaries. It consists of proteins such as Collagen IV. Too much of it can stiffen the capillary walls.

1) 🩸 New paper by the team of Ronald Davis.

They found that red blood cells from ME/CFS patients are slower and less responsive to low oxygen levels in a lab device that mimics small blood vessels. Image
2) Previous studies suggested that red blood cells change their shape more easily when oxygen is low. That allows them to move faster through small blood vessels (capillaries) and deliver oxygen where it is needed.
3) The red blood cells of ME/CFS patients do this as well, but they are less responsive to lower oxygen levels.

At normal oxygen levels (normoxia with partial oxygen pressure of 20-60 mmHg), they flowed as fast, or even faster, as those from healthy controls.

1) Interesting experiment on fatiguability of arm muscles that might be useful as an objective test.

During repeated handgrip tasks, researchers found that "the neuromuscular system experienced changes earlier than the actual behavior" Image
2) The experiment used multiple fatigue measures during the task:

– EMG = tiny electrical signals in the forearm muscles
– EEG = brain waves at the scalp
– fMRI = brain activity through blood oxygenation levels
– contraction force of the muscle
– a subjective fatigue scale.
3) These all showed the expected signs of fatigue:

- EMG shifted from high to low frequencies and more recruitment of motor units.

- EEG had increased power in multiple frequency bands

- fMRI showed an increase in the blood oxygen in the cerebellum.

1) In a new preview video, Dr. Yarred Younger from the University of Alabama says he found evidence that ME/CFS patients have more microglia cell activation in their brains than healthy controls.

His theory is that chronic brain inflammation is driving symptoms in ME/CFS. Image
2) A short recap of the evidence:

In a 2014 paper researchers, Japanese researchers reported neuro-inflammation in ME/CFS using PET-scans.
pubmed.ncbi.nlm.nih.gov/24665088/

A Dutch 2022 paper, however, found no difference between patients and controls
pubmed.ncbi.nlm.nih.gov/34815320/
3) Both were small studies with only 9 ME/CFS patients and they used an older and not so sensitive tracer ([¹¹C]-(R)-PK11195).

Younger got NIH funding for PET scans with a better, second-generation, ligand (18F-DPA-714)
