ME/CFS: the biology of a neglected disease
A group of South African and British researchers have reviewed the literature and described ME/CFS in terms of symptoms, severity and burden, diagnostic criteria, causes and triggers; followed by an overview of the complex pathophysiology and management of the condition. They conclude by listing research priorities for the future.
They emphasise the necessity of a holistic approach to diagnosing, researching, and treating ME/CFS, urging the scientific community to reconsider the disease’s complexity and the multifaceted approach required for its study and management.

ME/CFS symptoms
Patients display varying symptoms and several body systems are impacted: Immunological impairments; pain; gastrointestinal problems; autonomic dysfunction; respiratory issues. Although many of the symptoms overlap with other diseases, one feature that sets ME/CFS apart is a worsening of symptoms in response to relatively minor physical, cognitive, orthostatic or even emotional exertion. This phenomenon is known as post-exertional malaise (PEM) or PESE (post exertional symptom exacerbation).

The researchers find that research confirms our understanding of the range of severity of the disease and that despite its high prevalence, there are still no universally accepted clinical criteria to characterise ME/CFS, making early and accurate diagnosis difficult.
Probable causes of ME/CFS
The researchers conclude that “ME/CFS is likely to have a multifactorial origin, with multiple physiological processes implicated” in the way the disease develops. They discuss genetic presdisposition, viral triggers and reactivation, toxin and drug exposure.
The complex pathophysiology of ME/CFS
“As a consequence of infection and other stressors, such as poly-trauma for example, a state of acute inflammation and aberrant immune activation may occur. A compensatory anti-inflammatory mechanism then typically follows), causing an imbalance in immune responses combined with hypothesised autoimmunity. This may lead to subsequent physiological abnormalities including gut dysbiosis and systemic inflammation, eventually resulting in a pathological clotting system, chronic endothelialitis, vasoconstriction, and hypoxia, as found in similar conditions such as heat stroke. Additionally, dysfunctional energy metabolism along with oxidative stress are also hypothesised in the development of ME/CFS. It is hypothesised that these mechanisms occur in a spiralling, progressive way, toppling the host’s homeostatic equilibrium.” A detailed discussion is included.
Management of ME/CFS
No effective therapies and few established non-pharmacological treatments for ME/CFSwere found. Hence current advice is aimed at symptom management and lifestyle changes. The current available treatments/lifestyle modifications are summarised in the illustration.

The researchers conclude by making suggestions for future research and calls for increased support for the ME/CFS community. They also list some potential treatments for furhter investigation: Rintatolimod; steroids; mitochondrial nutraceutical; PPAR agonists; Activators of AMPK; Immunostimulative therapy; Antivirals; Antioxidants; Immunomodulators; B-cell depleting therapy; Immunoadsorption therapy.

The clinical problem is extremely difficult, with little or no formal evidence on which to base diagnosis-specific recommendations for care, or information about prognosis. In several cases, however, the problem has apparently been compounded by a lack of provision of adequate services, misunderstandings, and conflict between health care professionals over diagnosis and approach to management.

In early 2024 medical students at Scottish medical schools were invited to take part in an essay competition, 500 words on the topic of ‘What is your most important learning point about myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)?’
Dr Muirhead writes “ME/CFS affects at least 280,000 people in the UK, including approximately 23,000 in Scotland. It is a neurological disease with multisystem symptoms, often triggered by a virus. People with ME/CFS may be left bedbound or housebound with a significantly reduced quality of life. Yet many healthcare professionals do not know how to diagnose or manage this devastating disease, nor do they know how, or what, to teach our next generation of doctors.”

The 6 week programme was designed to support people experiencing feelings of breathlessness and anxiety with the aim of improving breath control, lung function, circulation, and posture. A major benefit seems to be the ability to experience something fun and relaxing in an understanding environment.
This course will not suit everybody but some people may feel they are well enough or are managing their symptoms sufficiently well to make space for it in their weekly management plan.
I want to tell you about the new way I’ve found to help me with my pain management. This is through the process of doing ‘Diamond Art, (DA).
A helpful trick I found was if I wrote the correct code with permanent ink on each pack of coloured beads, before I began to apply the beads to the canvas, this helped me visually and with my cognitive issues & brain fog. There are canvases with a range of complexity – simple to complex – to suit every cognitive experience.
