Health-related quality of life in patients with myalgic encephalomyelitis/chronic fatigue syndrome: an Australian cross-sectional study.

Abstract:

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious and debilitating disorder associated with significant disruptions in daily life including. This study aimed to examine the impact of sociodemographic and patient symptom characteristics on health-related quality of life (HRQoL) of Australians with ME/CFS.

METHODS: Self-reported data collected from 480 individuals diagnosed with ME/CFS were obtained between August 2014 and August 2018. This cross-sectional survey analysed sociodemographic, symptom characteristics and HRQoL according to the 36-Item Health Survey (SF-36). Multivariate linear regression models were used to determine ME/CFS symptoms associated with eight domains of HRQoL.

RESULTS: Reported HRQoL was significantly impaired in ME/CFS patients across all domains compared with the general population. Scores were the lowest for physical role (4.11 ± 15.07) and energy/fatigue (13.54 ± 13.94). Associations with females, higher body mass index (BMI), employment status, cognitive difficulties, sensory disturbances and cardiovascular symptoms were observed in the physical functioning domain. Impaired pain domain scores were associated with high BMI, annual visits to their general practitioner, flu-like symptoms and fluctuations in body temperature. Reduced well-being scores were associated with smoking status, psychiatric comorbidity, cognitive difficulties, sleep disturbances and gastrointestinal difficulties.

CONCLUSION: This study provides evidence that ME/CFS has a profound and negative impact on HRQoL in an Australian cohort.

Intimate Partner Violence and the Risk of Developing Fibromyalgia and Chronic Fatigue Syndrome

Abstract:

Intimate partner violence (IPV) is a global public health issue with a variety of ill health consequences associated with exposure. Due to the stimulation of chronic stress and inflammatory pathways, childhood abuse has been associated with the subsequent development of functional syndromes such as fibromyalgia and chronic fatigue syndrome (CFS). Although IPV in women appears to elicit similar biochemical responses, this association has not been tested thoroughly in IPV survivors. These functional syndromes are complex in etiology and any indication of their risk factors would benefit health care professionals managing this population. Therefore, we aimed to investigate the association between exposure to IPV with functional syndromes: fibromyalgia and CFS.

We conducted a retrospective open cohort study using “The Heath Improvement Network” database between January 1, 1995 and December 1, 2017. A total of 18,547 women who were exposed to IPV were each matched by age to four controls who were not exposed (n = 74,188). The main outcome measures were the risk of developing fibromyalgia and CFS. These were presented as adjusted incidence rate ratios (aIRR) with 95% confidence intervals (CIs).

We found that 97 women in the exposed group developed fibromyalgia (incidence rate [IR] = 1.63 per 1,000 person-years) compared to 239 women in the unexposed group (IR = 0.83 per 1,000 person-years). Following adjustment, this translated to an IRR of 1.73 (95% CI = [1.36, 2.22]). Similarly, 19 women developed CFS in the exposed group (IR = 0.32 per 1,000 person-years), compared to 53 in the unexposed group (0.18 per 1,000 person-years), which translates to an aIRR of 1.92 (95% CI = [1.11, 3.33]).

Therefore, we have identified an association between a history of IPV in women and the development of these functional syndromes, which may provide more information to inform the biopsychosocial pathway precipitating the development of fibromyalgia and CFS.

Editorial: Advances in ME/CFS Research and Clinical Care

Editorial:

Advances in ME/CFS Research and Clinical Care spotlights Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): a maligned, stigmatized, under-researched disease, which lacks a definitive, objective clinical test for its diagnosis, and definitive palliative and curative treatments. A few brave physicians attempt to alleviate the suffering of the afflicted. They rely upon the patients’ symptoms to guide them. Physicians can provide symptomatic relief and improve upon patients’ abnormal physiological and metabolic parameters by intervening to cause the latter to approach normal limits.

Documented to be more severely disabling than HIV-AIDS, ME/CFS receives disturbingly little funding in the United States and around the world. ME/CFS patients constitute an identifiable, underserved population that is in need of the recognition which would raise them from their current, underserved or non-served patient status into the mainstream of healthcare worldwide. ME/CFS is a common disease worldwide, affecting approximately 1 percent of the world’s population.

Work Rehabilitation and Medical Retirement for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Patients. A Review and Appraisal of Diagnostic Strategies

Abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome leads to severe functional impairment and work disability in a considerable number of patients. The majority of patients who manage to continue or return to work, work part-time instead of full time in a physically less demanding job. The prognosis in terms of returning to work is poor if patients have been on long-term sick leave for more than two to three years.

Being older and more ill when falling ill are associated with a worse employment outcome. Cognitive behavioural therapy and graded exercise therapy do not restore the ability to work. Consequently, many patients will eventually be medically retired depending on the requirements of the retirement policy, the progress that has been made since they have fallen ill in combination with the severity of their impairments compared to the sort of work they do or are offered to do.

However, there is one thing that occupational health physicians and other doctors can do to try and prevent chronic and severe incapacity in the absence of effective treatments. Patients who are given a period of enforced rest from the onset, have the best prognosis. Moreover, those who work or go back to work should not be forced to do more than they can to try and prevent relapses, long-term sick leave and medical retirement.

Factors associated with work status in chronic fatigue syndrome

Abstract:

BACKGROUND: Work status in people with chronic fatigue syndrome (CFS) has not been extensively researched.

AIMS: To explore occupational outcomes in patients with CFS by socio-demographic, well-being and disease characteristics.

METHODS: We assessed cross-sectional data from patients attending a UK specialist CFS treatment service between 1 January 2007 and 31 December 2014. The main outcome was self-reported current employment status: currently in employment, temporarily interrupted employment or permanently interrupted employment. Other variables included sex, age, ethnicity, education, marital status, CFS duration, fatigue severity, anxiety, depression, activity limitations and functional impairment. We used multinominal logistic regression models to identify factors associated with current work status.

RESULTS: Two hundred and seventy-nine (55%) patients were currently working, with 83 (16%) reporting temporarily interrupted employment and 146 (29%) stopping work altogether. Factors strongly associated with permanently interrupted employment were older age (adjusted odds ratio (AOR) 5.24; 95% CI 2.67-10.28), poorer functioning (AOR 6.41; 95% CI 3.65-11.24) and depressive symptoms (AOR 2.89; 95% CI 1.82-4.58) compared to patients currently working. Higher educated patients (AOR 0.60; 95% CI 0.37-0.97) and being in a relationship (AOR 0.34; 95% CI 0.21-0.54) were associated with being currently employed. Anxiety symptoms were common; 230 patients (45%) met caseness criteria.

CONCLUSIONS: Many patients with CFS were not working. This was exacerbated by high levels of depressive symptoms. Health professionals should assess co-morbid mental health conditions and consider treatment options when patients with CFS present themselves. The early involvement of occupational health practitioners is recommended to maximize the chances of maintaining employment.

Unemployment and work disability in individuals with chronic fatigue syndrome/myalgic encephalomyelitis: a community-based cross-sectional study from Spain

Abstract:

BACKGROUND: Few reports have examined the association between unemployment and work disability in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). This study explored the key determinants of work disability in a CFS/ME cohort.

METHODS: A community-based prospective study included 1086 CFS/ME patients aged 18-65 years. Demographic and clinical characteristics and outcome measures were recorded. Multiple linear regression analysis was performed to identify key risk indicators of work disability.

RESULTS: Four hundred and fifty patients with CFS/ME were employed (41.4%) and 636 were unemployed (58.6%). Older age at pain onset (OR: 1.44; 95% CI: 1. 12-1.84, autonomic dysfunction (OR: 2.21; 95% CI: 1.71-2.87), neurological symptom (OR: 1.66; 95% CI: 1. 30-2.13) and higher scores for fatigue (OR: 2.61; 95% CI: 2.01-3.39), pain (OR: 2.09; 95% CI: 1.47-2.97), depression (OR: 1.98; 95% CI: 1. 20-3.26), psychopathology (OR: 1.98; 95% CI: 1.51-2.61) and sleep dysfunction (OR: 1.47; 95% CI: 1. 14-1.90) were all associated with a higher risk of work disability due to illness.

CONCLUSIONS: Using an explanatory approach, our findings suggest that unemployment is consistently associated with an increased risk of work disability due to CFS/ME, although further more rigorous research is now needed to help in targeting interventions at the workplace.

The Relationship Between Chronic Fatigue Syndrome, Burnout, Job Satisfaction, Social Support And Age Among Academics At A Tertiary Institution

Abstract:

OBJECTIVES: Over the last 20 years, tertiary institutions have been subjected to several changes. This has resulted in increased workloads for academics. Some academics have started to experience symptoms that are related to chronic fatigue syndrome and burnout. Researchers, however, cannot agree whether the 2 syndromes are two sides of the same coin or actually 2 separate constructs. This study that was conducted at a tertiary institution in South Africa therefore aimed to determine if these constructs accounted for the evidence of the same syndrome within an academic setting or if they were 2 separate, distinguishable constructs. However, since job satisfaction and social support play a role in the poor physical and psychological health experienced by individuals with chronic fatigue syndrome or burnout, it was decided to also include these 2 constructs into the investigation. Age was also incorporated because it had dissimilar relationships with burnout and chronic fatigue syndrome.

MATERIAL AND METHODS: The participants completed the following questionnaires via an online survey: The Centers for Disease Control and Prevention Chronic Fatigue Syndrome Symptom Inventory, the Oldenburg Burnout Inventory, the Overall Job Satisfaction Scale and the Social Support Scale. The data was used for constructing a structural equation model.

RESULTS: Job satisfaction was found to be a strong predictor of burnout. The number of symptoms indicative of chronic fatigue syndrome reported by the participants proved to be a relatively strong significant predictor of burnout. Age did not yield any significant relationship with any of the constructs.

CONCLUSIONS: The results indicated that chronic fatigue and burnout should be perceived as 2 distinguishable constructs in the academic context. It should be noted, however, that some overlap exists between them.

A Validated Scale for Assessing the Severity of Acute Infectious Mononucleosis

Abstract:

OBJECTIVES: To develop a scale for the severity of mononucleosis.

STUDY DESIGN: One to 5 percent of college students develop infectious mononucleosis annually, and about 10% meet criteria for chronic fatigue syndrome (CFS) 6 months following infectious mononucleosis. We developed a severity of mononucleosis scale based on a review of the literature. College students were enrolled, generally when they were healthy. When the students developed infectious mononucleosis, an assessment was made as to the severity of their infectious mononucleosis independently by 2 physicians using the severity of mononucleosis scale. This scale was correlated with corticosteroid use and hospitalization. Six months following infectious mononucleosis, an assessment is made for recovery from infectious mononucleosis or meeting 1 or more case definitions of CFS.

RESULTS: In total, 126 severity of mononucleosis scales were analyzed. The concordance between the 2 physician reviewers was 95%. All 3 hospitalized subjects had severity of mononucleosis scores ≥2. Subjects with severity of mononucleosis scores of ≥1 were 1.83 times as likely to be given corticosteroids. Students with severity of mononucleosis scores of 0 or 1 were less likely to meet more than 1 case definition of CFS 6 months following infectious mononucleosis.

CONCLUSIONS: The severity of mononucleosis scale has interobserver, concurrent and predictive validity for hospitalization, corticosteroid use, and meeting criteria for CFS 6 months following infectious mononucleosis.

Prevalence and characteristics of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) in Poland: a cross-sectional study

Abstract:

OBJECTIVES: The aim of this study was to estimate the prevalence of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and describe illness characteristics in a community population in Poland.

DESIGN: cross-sectional study.

SETTING: Poland.

PARTICIPANTS: Of the cohort of 1400 who self-presented with fatigue only 69 subsequently were confirmed as having CFS/ME using the Fukuda criteria.

MAIN OUTCOME MEASURES: Participants completed the following screening symptom assessment tools: Chalder Fatigue Scale, Hospital Anxiety and Depression Scale (HADS), Epworth Sleepiness Scale (ESS), Composite Autonomic Symptom Score 31 (COMPASS 31), Quality of Life Scale (QOLS). Haemodynamic and autonomic parameters were automatically measured at rest with a Task Force Monitor.

RESULTS: In 1308, from 1400 (93%) individuals who identified themselves as fatigued, recognised chronic conditions were identified, for example, neurological (n=280, 21.5%), neurodegenerative (n=200, 15%), psychiatric (n=654, 50%) and immunologic (n=174, 13.5%) disorders. The remaining 69 participants (mean age 38.3±8.5) met the Fukuda defintion for CFS/ME and had baseline objective assessment. The majority had experienced symptoms for over 2 years with 37% having symptoms for 2-5 years and 21.7% for more than 10 years. The COMPASS 31 indicated that 50% have symptoms consistent with orthostatic intolerance. About 43/69 (62%) had Epworth sleepiness scores ≥10, ie, consistent with excessive daytime sleepiness, 26/69 (38%) had significant anxiety and 22/69 (32%) depression measured by HADS A & D. Quality of life is significantly impaired in those with Fukuda criteria CFS (QLS score 64±11) with significant negative relationships between quality of life and fatigue (p<0.0001), anxiety (p=0.0009), depression (p<0.0001) and autonomic symptoms (p=0.04).

CONCLUSION: This is the first study to summarise illness characteristics of Polish CFS/ME patients. Our study has confirmed that fatigue is a common and under-recognised symptom affecting the Polish population.

No evidence found for an increased risk of long-term fatigue following human papillomavirus vaccination of adolescent girls

Abstract:

INTRODUCTION: In 2013, the Netherlands Pharmacovigilance Center Lareb published an overview of reports of long-lasting fatigue following bivalent HPV-vaccination (2vHPV). After an update of this overview in 2015, concerns regarding the safety of 2vHPV was picked up by the media, which led to further reports of long-lasting fatigue. Therefore, the Dutch National Institute for Public Health and the Environment (RIVM) investigated a possible association between HPV-vaccination and long-term fatigue.

METHODS: In this retrospective cohort study conducted in the Integrated Primary Care Information database, we investigated the occurrence of chronic fatigue syndrome (CFS), fatigue ≥6 months and 3-6 months in all girls born in 1991-2000 during the follow-up period January 1st 2007-December 31st 2014 (2007-2008 pre-vaccination and 2009-2014 post-vaccination). Patients with certain fatigue ≥6 m were asked for consent to link their primary care information with vaccination data. Incidence rates per 10,000 person years (PY) for 12-16-year-old girls were compared between pre- and post-HPV-vaccine era. A self-controlled case series (SCCS) analysis was performed using consenting vaccinated cases. A primary high-risk period of 12 months after each dose was defined.

RESULTS: The cohort consisted of 69,429 12-16-year-old girls accounting for 2758 PY pre-vaccination and 57,214 PY post-vaccination. Differences between pre- and post-vaccination incidences (CFS: 3.6 (95% CI 0.5-25.7)/10,000 PY and 0.9 (0.4-2.1); certain fatigue ≥6 m: 7.3 (1.8-29.0) and 19.4 (16.1-23.4); certain fatigue 3-6 m: 0.0 and 16.6 (13.6-20.3), respectively) were not statistically significant. SCCS analyses in 16 consenting vaccinated cases resulted in an age-adjusted RR of 0.62 (95%CI 0.07-5.49).

CONCLUSIONS: Fatigue ≥6 m and 3-6 m was frequently found among adolescent girls, but CFS was rarely diagnosed. No statistically significant increased incidence rates were found post-vaccination compared to similar age groups of girls pre-vaccination. The SCCS analysis included a low number of cases but revealed no elevated risk of certain fatigue ≥6 m in the high-risk period.
