Symptom-based clusters in people with ME/CFS: an illustration of clinical variety in a cross-sectional cohort

Abstract:

Background: Myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) is a complex, heterogenous disease. It has been suggested that subgroups of people with ME/CFS exist, displaying a specific cluster of symptoms. Investigating symptom-based clusters may provide a better understanding of ME/CFS. Therefore, this study aimed to identify clusters in people with ME/CFS based on the frequency and severity of symptoms.

Methods: Members of the Dutch ME/CFS Foundation completed an online version of the DePaul Symptom Questionnaire version 2. Self-organizing maps (SOM) were used to generate symptom-based clusters using severity and frequency scores of the 79 measured symptoms. An extra dataset (n = 252) was used to assess the reproducibility of the symptom-based clusters.

Results: Data of 337 participants were analyzed (82% female; median (IQR) age: 55 (44–63) years). 45 clusters were identified, of which 13 clusters included ≥ 10 patients. Fatigue and PEM were reported across all of the symptom-based clusters, but the clusters were defined by a distinct pattern of symptom severity and frequency, as well as differences in clinical characteristics. 11% of the patients could not be classified into one of the 13 largest clusters. Applying the trained SOM to validation sample, resulted in a similar symptom pattern compared the Dutch dataset.

Conclusion: This study demonstrated that in ME/CFS there are subgroups of patients displaying a similar pattern of symptoms. These symptom-based clusters were confirmed in an independent ME/CFS sample. Classification of ME/CFS patients according to severity and symptom patterns might be useful to develop tailored treatment options.

Investigating undergraduate medical education on myalgic encephalomyelitis/chronic fatigue syndrome

Abstract:

Background and Objectives: ME/CFS is a poorly understood, highly stigmatised condition which significantly reduces patients’ quality of life. ME/CFS had been identified as a gap in many health professionals’ knowledge, therefore this research aims to explore the understanding of ME/CFS amongst UK medical students.

Methods: An online survey developed using Redcap was distributed to participants who were recruited via social media or via medical societies’ emails. The participants were undergraduate UK medical students.

Results: 94 students completed the survey from more than 16 medical schools. 35% of the students did not know what ME/CFS is and 88% say that the disease has not been covered in their course so far. 89% of participants would like to learn more about ME/CFS, specifically through elearning and videos.

Discussion: Participants were generally unaware of ME/CFS and its symptoms and had not received relevant teaching or exposure to the disease. Education on ME/CFS within undergraduate UK medical schools is currently inadequate and the interest expressed by students in this survey demonstrates a new teaching opportunity for UK medical schools.

Impact of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) on the quality of life of people with ME/CFS and their partners and family members: an online cross-sectional survey

Abstract:

Objectives: The aim of this study was to assess the impact of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) on the quality of life (QoL) of people with ME/CFS and their relative or partner (family member).

Design: A patient-partner, multinational, subject-initiated, cross-sectional online survey.

Setting: International survey using ME/CFS charities, support groups and social media.

Participants: Participants were self-selected with recruitment via social media. Inclusion criteria were aged 18 years or over and reported diagnosis of ME/CFS by health professional. 1418 people with ME/CFS and their 1418 family members from 30 countries participated in the survey. Participants with ME/CFS had a mean age of 45.8 years (range 18-81) and were predominantly women (1214 (85.6%) of 1418). Family members had a mean age of 51.9 years (range 18-87) and were predominantly men (women: 504 (35.5%) of 1418). 991 (70%) family members were partners of the people with ME/CFS.

Interventions: EuroQoL-5 Dimension (EQ-5D-3L), completed by people with ME/CFS, and Family Reported Outcome Measure (FROM-16) questionnaire, completed by family members.

Results: The mean overall health status on a Visual Analogue Scale for people with ME/CFS was 33.8 (0=worst, 100=best). People with ME/CFS were most affected by ability to perform usual activities, pain, mobility, self-care and least impacted by anxiety. For family members, the overall mean FROM-16 score was 17.9 (0=no impact, 32=worst impact), demonstrating a major impact on QoL. Impact on QoL was significantly correlated between the person with ME/CFS and their family member (p<0.0001). Family members were most impacted emotionally by worry, frustration and sadness and personally by family activities, holidays, sex life and finances.

Conclusions: To the best of our knowledge, this is the largest study on the impact of the QoL of persons with ME/CFS and their family members. While open participation surveys are limited by selection bias, this research has revealed a significant worldwide burden of ME/CFS on the QoL of people with ME/CFS and their family members.

Survey of people with Myalgic Encephalomyelitis (ME) to explore their use and experiences of physiotherapy services in the UK

Abstract:

250,000 people live with Myalgic Encephalitis (ME) in the UK, this compares to 100,000 living with Multiple Sclerosis. In 2019, a survey by MEAction of 1906 people with ME, identified that over 50% of people who attended specialists ME clinics, employing physiotherapists, were unsatisfied with the services. People with ME (PwME) are also seen in regular musculoskeletal, community, neurological and paediatric physiotherapy services but the views of PwME related to these services are not known. The aim of this present survey, therefore, was to identify the experiences of PwME of physiotherapy services throughout all areas of physiotherapy practice.

Impacts of online support groups on quality of life, and perceived anxiety and depression in those with ME/CFS: A survey

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating condition that can negatively affect physical and mental health [1,2]. People with ME/CFS report lower perceived levels of social support, which further exacerbate challenges with mental health and has been linked to a higher prevalence of depression and anxiety in this population [3]. There are many mental health benefits associated with participation in in-person support groups; however, it is unknown if these benefits translate to online support groups [5].

Purpose: To examine the perceived impacts of participation in online support groups on depression, anxiety and quality of life among people with ME/CFS.

Results: Responses (n = 76) to an online survey indicated positive and negative experiences with participation in online support groups. Positive experiences included a sense of belonging, validation, supportive friendships and feelings of positively impacting others. Negative experiences included jealousy, decreased hope and optimism and disagreement regarding treatment strategies.

Conclusion: Participation in online support groups was believed to decrease perceived feelings of depression and increase the quality of life in those with ME/CFS. No significant impacts on anxiety were found. Overall, participants reported engagement in online support groups to be a positive experience.

Report on the impact of Covid-19 on ME

Summary:

This summary report provides the preliminary findings from responses to the survey we are carrying out, in partnership with Action for ME, to identify the impact that Covid-19 has on people with ME. The report is based on the analysis of the 220 responses received in the three weeks after the survey went live in late March.

These initial responses show clearly that Covid-19 had a significant impact on respondents, with more than three quarters (76%) of respondents saying that Covid-19 made their ME symptoms worse. This impact appears to be long lasting, with over two thirds of respondents reporting that the worsening in symptoms has lasted more than 6 months and have still not resolved.

The wider impact of Covid-19 is illustrated by the negative impacts on the health of respondents, including 72% reporting new symptoms. The analysis also shows that respondents’ ability to attend education or work had decreased and their use of health services had increased significantly, highlighting the potential economic impact of Covid-19.

Specifics of chronic fatigue syndrome coping strategies identified in a French flash survey during the COVID-19 containment

Abstract:

The COVID-19 pandemic has focused health systems on supporting patients affected by this virus. Meanwhile in the community, many other contained patients could only use self-care strategies, especially in countries that have set up a long and strict containment such as France. The study aimed to compare coping strategies deployed by patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS; a poorly recognised syndrome) to those with better known and referenced chronic conditions. An online flash survey was conducted during the containment period in partnership with French Patients Organizations including ME/CFS national association. Therefore, ‘Brief COPE’ version of Lazarus and Folkman’s Ways of Coping Check List has been adapted to the specificity of the containment.

The survey was e-distributed in France from 15 April to 11 May 2020. Differences of coping strategies were analyzed using Wilcoxon-Mann-Withney test. Amongst 637 responses, 192 were complete, presenting a wide variety of diseases, including 93 ME/CFS. The latter have significantly different coping strategies than recognised diagnosed diseases patients: similar uses of emotion focused coping but less uses of seek social support and problem-focused copings.

In conclusion, coping strategies are different for those who deal with the daily experience of ME/CFS, highly disabling chronic condition with diagnostic ambiguity, low degree of medical and social recognition and without treatment. Better understanding of those strategies is needed to provide the means for health promotion researchers, managers and clinicians, to accompany those patients.

Comparative Survey of People with ME/CFS in Italy, Latvia, and the UK: A Report on Behalf of the Socioeconomics Working Group of the European ME/CFS Research Network (EUROMENE)

Abstract:

Background and Objectives: A comparative survey of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients was carried out in three countries, with the aim of identifying appropriate policy measures designed to alleviate the burden of disease both on patients and their families, and also on public institutions. The survey addressed demographic features, the economic impact of the disease on household incomes, patterns of medical and social care, specific therapies, social relationships, and the impact of the illness on quality of life.

Materials and Methods: Parallel surveys were undertaken in Italy, Latvia, and the UK. There were 88 completed responses from Italy, 75 from Latvia, and 448 from the UK. To facilitate comparisons, 95% confidence intervals were calculated in respect of responses to questions from all three countries. To explore to what extent general practitioners (GPs) manage ME/CFS disease, a separate questionnaire for GPs, with questions about the criteria for granting a diagnosis, laboratory examinations, the involvement of specialists, and methods of treatment, was undertaken in Latvia, and there were 91 completed responses from GPs.

Results: The results are presented in respect of sociodemographic information, household income, disease progression and management, perceived effectiveness of treatment, responsibility for medical care, personal care, difficulty explaining the illness, and quality of life. Demographic details were similar in all three countries, and the impact of illness on net household incomes and quality of life. There were significant differences between the three countries in illness progression and management, which may reflect differences in patterns of health care and in societal attitudes. Graded exercise therapy, practiced in the UK, was found to be universally ineffective.

Conclusions: There were similarities between respondents in all three countries in terms of demographic features, the impact of the illness on household incomes and on quality of life, and on difficulties experienced by respondents in discussing their illness with doctors, but also differences in patterns of medical care, availability of social care, and societal attitudes to ME/CFS.

Survey: Doctor’s Knowledge and Understanding of ME, 2018

It has long been the experience of patients with Myalgic Encephalomyelitis (ME) that their doctors have little knowledge and understanding of the condition, and are largely unable to help. Worse, many report that their doctors do not appear to believe their illness is real, resulting in tragic lack of support.

Examination of sample medical curriculums in the United Kingdom in 2018 confirmed that as far as could be determined, Myalgic Encephalomyelitis was not in the syllabus at either undergraduate or postgraduate levels. It is therefore quite conceivable that patients’ widely reported impression is indeed true.

Paediatric patients with myalgic encephalomyelitis/chronic fatigue syndrome value understanding and help to move on with their lives

Abstract:

AIM: The aim of this study was to document qualitative questionnaire feedback regarding management from a cohort observational study of young people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

METHODS: Between 1991 and 2009, 784 paediatric patients, age 6-18 years, were diagnosed with ME/CFS following referral to a specialised clinic at the Royal Children’s Hospital, Melbourne. Over a 14-year period, feedback was requested on up to seven occasions. Management included the following: symptom management and a self-management lifestyle plan that included social, educational, physical and a pleasurable activity outside of home. They adjusted it by severity of illness, stage of education, family circumstances and life interests.

RESULTS: Questionnaires were returned from 626 (80%) with 44% providing feedback more than once. They reported that their management plan allowed them to regain control over their lives. They cited early diagnosis, empathetic, informed physicians, self-management strategies and educational liaison as helping them to function and remain socially engaged. Ongoing support, particularly assistance to navigate the education system, was essential for general well-being and ability to cope.

CONCLUSION: Young people valued regaining the control over their lives that was lost through illness, support to maintain social contacts and assistance to achieve educational and/or life goals.
