An Overview of Severe Myalgic Encephalomyelitis

Abstract:

In this article, we have reviewed the literature on severe myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). ME/CFS is a clinical diagnosis in the absence of a diagnostic test. However, in research settings and disability disputes, 2-day cardiopulmonary exercise testing can be used to diagnose and document the abnormal response to exercise. Biomedical research into this disease has been scarce and underfunded for decades. Consequently, there are no effective treatments.

In its most severe form, it is more disabling than many other diseases, and patients are bedbound 24/7, dependent on carers, and spend their days in dark and quiet rooms. Even the soft sound of a human voice can lead to further deterioration. Some of the very severely ill suffer from life-threatening malnutrition and need to be tube-fed. The COVID-19 pandemic has led to a sharp increase in the number of patients with post-infectious diseases, and many of them fulfill ME/CFS criteria.

Dedicated, focused research using advanced medical technologies is needed to gain further understanding of the underlying disease mechanism. This will enable us to find effective pharmacological treatments and address the unmet medical needs of these very ill people.

A patient perspective on enduring symptoms – the unmet need

Abstract:

This short paper illustrates the lived experience of individuals with severe enduring symptoms: chronic, often debilitating conditions for which no clear medical explanation currently exists. Drawing on qualitative interviews, the paper highlights the profound suffering, isolation, and lack of medical support experienced by this underserved population. It examines the systemic barriers to care, including stigma, the absence of follow-up services, and the traumatising nature of some healthcare encounters, which can lead to healthcare avoidance even in the face of potentially life-threatening symptoms. It concludes with a call for improved training for clinicians, increased capacity within NHS services, and ring-fenced funding for biomedical research.

Severe and Very Severe Myalgic Encephalopathy/Chronic Fatigue Syndrome ME/CFS in Norway: Symptom Burden and Access to Care

Abstract:

There is a striking lack of systematic knowledge regarding the symptom burden, capacity for activities of daily living, and supportive measures for the most severely ill ME/CFS patients. The present study seeks to address this through a national, Internet-based survey targeting patients with severe and very severe ME/CFS and their carers.
Responses from 491 patients were included, with 444 having severe and 47 very severe ME/CFS with the classification based on the best estimate from patient responses. In addition, 95 respondents were reclassified from patients’ own classification to moderate and included for comparison. The onset was before 15 years of age for 45% in the very severe and 32% in the severe group. Disease duration was more than 15 years for 19% in the very severe and 27% in the severe group. Patient symptom burden was extensive. The most severely affected were totally bedridden, unable to talk, and experienced dramatic worsening of symptoms after minimal activity or sensory stimuli.
Care and assistance from healthcare and social services were often described as insufficient or inadequate, often worsening the symptom load and burden of care. A substantial lack of disease knowledge among healthcare providers in general was reported. Yet approximately 60% in the severe and very severe groups found services provided by occupational therapists and family doctors (general practitioners) helpful, while a smaller proportion experienced appropriate help from other health personnel groups. This indicates that help and support are highly needed and possible to provide. On the other hand, this must be approached carefully, as a substantial number of patients experienced deterioration from contact with healthcare personnel. Family carers described an extensive burden of care with often inadequate help from healthcare providers or municipal authorities.
Patient care by family members of very severe ME/CFS patients constituted more than 40 h a week for 71% of this patient group. The carers described a large negative impact on their work and financial situation, and on their mental wellbeing. We conclude that childhood onset was common, burden of disease was extensive, and support from responsible societal health and social support providers was commonly grossly inadequate.

Homebound versus Bedridden Status among Those with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Abstract:

Persons living with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) vary widely in terms of the severity of their illness. It is estimated that of those living with ME/CFS in the United States, about 385,000 are homebound. There is a need to know more about different degrees of being homebound within this severely affected group. The current study examined an international sample of 2138 study participants with ME/CFS, of whom 549 were severely affected (operationalized as ‘Homebound’). A subsample of 89 very severely affected participants (operationalized as ‘Homebound-bedridden’) was also examined. The findings showed a significant association between severely and very severely affected participants within the post-exertional malaise (PEM) symptom domain. The implications of these findings are discussed.
