Response to treatment in the Multiple Symptoms Study 3 trial

Letter:
Chistopher Burton and colleagues conducted an unblinded trial of a consultative intervention for 354 people with persistent physical symptoms but no identifiable “organic” cause. Patient Health Questionnaire-15 (PHQ-15) score, which is a brief, subjective, self-administered screen of severity of somatic complaints, was the primary outcome. This kind of trial design can be expected to produce modest positive outcomes, via expectation bias alone. No real-life, objective assessment of functioning was conducted.
The intervention involved up to four sessions with a general practitioner, offering patients “rational explanations” for their symptoms in the absence of known, falsifiable causes and helping patients to develop strategies for managing symptoms. Although the “rational explanations” are not described, they presumably did not include “organic” diseases or conditions.
Scores on the PHQ-15 range from 0 to 30. Recruited patients had scores from 10 to 20, indicating moderate severity. At the end of the study, the adjusted between-group difference of –1·82 did not reach the minimal clinically important difference of 2·3. The change is well within what would be expected from bias alone. The results therefore confirmed that the intervention was of limited, if any, practical benefit. However, the paper presents the findings as though they had shown the opposite.
Instead of the “rational explanations” promoted by the investigators, more straightforward and honest explanations—for example, we do not know what is causing symptoms—could easily have produced similar results. Patients desire resolution of symptoms and recovery of functions. The trial did not achieve this result. Post-intervention, participants continue to have an impaired quality of life and poor experiences of health care.

“I still can’t forget those words”: mixed methods study of the persisting impact on patients reporting psychosomatic and psychiatric misdiagnoses

Abstract:

Objectives: This research aimed to improve understanding of persisting impacts of patient-reported psychosomatic and psychiatric misdiagnoses on patients with systemic autoimmune rheumatic diseases (SARDs).
Methods: Mixed methods data from two SARDs cohorts were analysed (N = 1,543 and N = 1,853). Validated instruments and patient-designed questions were used to measure self-reported depression, anxiety and mental wellbeing, in addition to medical relationships and healthcare behaviours. Comparative tests were used to evaluate differences between patients reporting a psychosomatic and/or psychiatric misdiagnoses and other patients.
Results: Persisting adverse outcomes of perceived psychosomatic and psychiatric misdiagnoses were identified in multiple domains. This included >80% of patients reporting that it had damaged their self-worth, and 72% reporting that it still upset them. Patients reporting psychosomatic and/or psychiatric misdiagnoses had significantly lower mental wellbeing, and higher depression and anxiety levels (all p< 0.001), and lower levels of satisfaction with every aspect of medical care, compared with patients reporting no psychosomatic or psychiatric misdiagnoses. Psychosomatic and psychiatric misdiagnoses had varying associations with healthcare behaviours, including a significantly higher likelihood of under-reporting symptoms (p< 0.001) and healthcare avoidance (p= 0.012), but not with medication adherence (p= 0.2). Thematic analysis of qualitative data revealed that symptom under-reporting and healthcare avoidance often resulted from distrust and fear that symptoms would be disbelieved and misattributed again.
Conclusion: Patient-reported psychosomatic and psychiatric (mis)diagnoses are associated with persisting adverse impacts in multiple domains including mental health, medical relationships, self-worth, and some healthcare behaviours. Health services and clinicians should consider these potential adverse impacts on patients and offer support to reduce any persisting negative impacts.

Relationship between major depressive disorder and myalgic encephalomyelitis/chronic fatigue syndrome: a two-sample mendelian randomization study analysis

Abstract:

Major depressive disorder (MDD) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) frequently occur together; yet their causal relationship remains unclear. To investigate the potential genetic causal link between these conditions, we conducted a two-sample Mendelian randomization (MR) analysis.

Summary data from Genome-Wide Association Studies (GWAS) for MDD were sourced from the UK Biobank and the Psychiatric Genomics Consortium, while GWAS data for ME/CFS were retrieved from the UK Biobank. Inverse-variance weighting (IVW), the MR-Egger method, and weighted median, simple and weighted modes were used to perform the MR analysis. In addition, Cochrane’s Q-test was used to detect heterogeneity among the MR results. Horizontal pleiotropy was detected using the MR-Egger intercept and the MR pleiotropy residual sum and outlier (MR-PRESSO) tests. Leave-one-out analysis was performed to investigate the sensitivity of the association between MDD and ME/CFS.

The results of the MR analysis revealed no causal relationship between MDD and ME/CFS. The pleiotropy test revealed that causality bias was improbable, and no evidence of heterogeneity was found among the genetic variants. Finally, the leave-one-out test confirmed the stability and robustness of our findings.

Re-visiting professional ethics in psychotherapy: reflections on the use of talking therapies as a supportive adjunct for myalgic encephalomyelitis/chronic fatigue syndrome and ‘medically unexplained symptoms’

Abstract:

Following years of debate over the effectiveness of cognitive behavioural therapy for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), public health bodies in the UK and beyond have determined that no psychotherapy is clinically proven for this patient group. In the field of ME/CFS and the wider arena of ‘medically unexplained symptoms’ (MUS), patient survey data and qualitative research capturing patient experiences and psychotherapist attitudes suggest that therapeutic practice may sometimes fall short of required ethical standards. This raises questions about how psychotherapists can safely support, as opposed to treat, people with these debilitating conditions.

We consider four ethical principles that feature throughout psychotherapists’ codes of practice, those of respect, competence, responsibility and integrity, and discuss examples of good and poor practice in this arena as evinced by recent empirical literature.

Following this, we offer a variety of suggestions to help strengthen ethical psychotherapy practice with patients with ME/CFS and other MUS. In terms of practitioner education, we recommend greater emphasis on humility, reflexivity and disability-affirming practices, exploration of personal as well professional ethics, and integration of patient expertise-by-experience, accompanied with the latest evidence, into foundational and ongoing training.

In terms of ongoing practice, we suggest consideration of formalised patient-focused feedback systems and greater transparency vis-à-vis patient access to clinical notes. Finally, we underline the importance of elevating patients from mere subjects to co-producers of psychotherapy research.

‘You don’t want to get better’: the outdated treatment of ME/CFS patients is a national scandal

By George Monbiot

It’s the greatest medical scandal of the 21st century. For decades, patients with ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) have been told they can make themselves better by changing their attitudes. This devastating condition, which afflicts about 250,000 people in the UK, was psychologised by many doctors and scientists, adding to the burden of a terrible physiological illness.

Long after this approach was debunked in scientific literature, clinicians who championed it have refused to let go. They continue to influence healthcare systems, governments and health insurers. And patients still suffer as a result.

Identifying the mental health burden in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients in Switzerland: A pilot study

Highlights:

  • First time study on mental health and well-being among ME/CFS patients in Switzerland.
  • High level (68.5%) of stigmatization reported due to ME/CFS.
  • Overall, ME/CFS led to a third of the patients and to half of the male patients to have suicidal thoughts.
  • ME/CFS led to secondary depression in 14.8% of the patients.
  • Lack of disease recognition and adequate patient support.

Abstract:

Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating chronic disease of significant public health and clinical importance. It affects multiple systems in the body and has neuro-immunological characteristics. The disease is characterized by a prominent symptom called post-exertional malaise (PEM), as well as abnormalities in the immune-inflammatory pathways, mitochondrial dysfunctions and disturbances in neuroendocrine pathways. The purpose of this study was to evaluate the impact of ME/CFS on the mental health and secondary psychosocial manifestations of patients, as well as their coping mechanisms.

Method: In 2021, a descriptive cross-sectional study was conducted in Switzerland. A self-administered paper questionnaire survey was used to gather data from 169 individuals diagnosed with ME/CFS.

Results: The majority of the patients (90.5%) reported a lack of understanding of their disease, resulting in patients avoiding talking about the disease due to disbelief, trivialization and avoidance of negative reactions. They felt most supported by close family members (67.1%). Two thirds of the patients (68.5%) experienced stigmatization. ME/CFS had a negative impact on mental health in most patients (88.2%), leading to sadness (71%), hopelessness for relief (66.9%), suicidal thoughts (39.3%) and secondary depression (14.8%). Half of the male patients experienced at least one suicidal thought since clinical onset. Factors significantly associated with depression were the lack of cure, disabilities associated with ME/CFS, social isolation and the fact that life was not worth anymore with ME/CFS. The three main factors contributing to suicidal thoughts were (i) being told the disease was only psychosomatic (89.5%), (ii) being at the end of one’s strength (80.7%) and (iii) not feeling being understood by others (80.7%).

Conclusion: This study provided first time significant insights into the mental and psychological well-being of ME/CFS patients in Switzerland. The findings highlight the substantial experiences of stigmatization, secondary depression and suicidal thoughts compared to other chronic diseases, calling for an urgent need in Switzerland to improve ME/CFS patient’s medical, psychological and social support, in order to alleviate the severe mental health burden associated with this overlooked somatic disease.

Confirmation of COVID-19 infection status and reporting of Long COVID symptoms in a population-based birth cohort: No evidence of a nocebo effect

Abstract:

Some patients with COVID-19 develop symptoms after the acute infection, known as ‘Long COVID’. We examined whether or not confirmation of COVID-19 infection status could act as a nocebo, using data from questionnaires distributed to the Avon Longitudinal Study of Parents and Children cohort.
We examined associations between confirmation of COVID-19 infection status (confirmed by a positive test vs unconfirmed) and reporting of Long COVID symptoms. We explored the roles of sex and anxiety as potential moderators.
There was no clear evidence of a strong association between confirmation of COVID-19 infection status and the Long COVID composite score, physical or psychological symptoms or duration of symptoms. There was no clear evidence of moderation by sex or anxiety. We therefore found no evidence of a nocebo effect. Our data suggest that this psychological mechanism does not play a role in the medical symptomatology experienced by patients with Long COVID.

Why the Psychosomatic View on Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Is Inconsistent with Current Evidence and Harmful to Patients

Abstract:

Since 1969, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has been classified as a neurological disease in the International Classification of Diseases by the World Health Organization. Although numerous studies over time have uncovered organic abnormalities in patients with ME/CFS, and the majority of researchers to date classify the disease as organic, many physicians still believe that ME/CFS is a psychosomatic illness.
In this article, we show how detrimental this belief is to the care and well-being of affected patients and, as a consequence, how important the education of physicians and the public is to stop misdiagnosis, mistreatment, and stigmatization on the grounds of incorrect psychosomatic attributions about the etiology and clinical course of ME/CFS.

Compelled loneliness and necessitated social isolation: “It’s like being on the other side of a mirror, just looking in”

Abstract:

This article develops the conceptualisation of loneliness by drawing on 42 accounts of myalgic encephalomyelitis (ME). While illness experience is a central concern of the sociology of health and illness, experiences of loneliness alongside contested and chronic illness have received less attention. The analysis illustrates how loneliness can be an integral part of living with ME and offers two novel conceptual contributions – necessitated social isolation and compelled loneliness.

Necessitated social isolation concerns how ME symptoms can make social lives increasingly restricted. Compelled loneliness highlights how the combined experiences of both stigma and contested illness can lead to social withdrawal and rejection, which create a sense of loneliness. The article argues that loneliness and social isolation can be conceptually distinct yet recursive and overlapping.

With the worsening of ME, the participants experienced a cycle of loneliness, in which social isolation and loneliness reproduced each other. Three key themes draw attention to how loneliness is affected by the situational aspects of living with a chronic and contested illness: (1.) spatial and temporal restrictedness (2.) communicative alienation and (3.) discreditation. The article highlights how health challenges can impact on loneliness and how the stigma of contested illness exacerbates loneliness.

Post-Traumatic Stress Disorder and Complex Post-Traumatic Stress Disorder in people with long COVID, ME/CFS, and controls

Abstract:

Background: Prevalences of Post-Traumatic Stress Disorder (PTSD) and Complex Post-Traumatic Stress Disorder (CPTSD) have not previously been compared between individuals with long COVID and individuals with Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome (ME/CFS), and healthy age-matched controls. For these reasons, this study aimed to determine the prevalence of PTSD and CPTSD in individuals with long COVID (n=21) and ME/CFS (n=20) and age-matched controls (n=20).

Methods: A case-case-control approach was employed, participants completed the International Trauma Questionnaire (ITQ), a self-report measure of the International Classification of Diseases (ICD-11) of PTSD and CPTSD consisting of 18 items. Scores were calculated for each PTSD and Disturbances in Self-Organization (DSO) symptom cluster and summed to produce PTSD and DSO scores. PTSD was diagnosed if the criteria for PTSD were met but not DSO, and CPTSD was diagnosed if the criteria for PTSD and DSO were met. Moreover, each cluster of PTSD and DSO were compared among individuals with long COVID, ME/CFS and healthy controls.

Results: Individuals with long COVID (PTSD= 5%, CPTSD= 33%) had more prevalence of PTSD and CPTSD than individuals with ME/CFS (PTSD= 0%, CPTSD= 20%) and healthy controls (PTSD= 0%, CPTSD= 0%). PTSD and CPTSD prevalence was greater in individuals with long COVID and ME/CFS than controls. Individuals with long COVID had greater values controls for all PTSD values. Moreover, individuals with long COVID had greater values than controls for all DSO values. Individuals with ME/CFS had greater values than controls for all DSO values. Both long COVID and ME/CFS groups differed in overall symptom scores compared to controls.

Conclusion: Findings of this study demonstrated that individuals with long COVID generally had more cases of PTSD and CPTSD than individuals with ME/CFS and healthy controls.
