Medically Documenting Disability in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Cases

Introduction:

Patients with severe myalgic encephalomyelitis/Chronic fatigue syndrome (ME/CFS) experience debilitating physical and cognitive symptoms, which often result in the need to file disability claims. A significant number of ME/CFS patients are children or adolescents. ME/CFS patients often turn to physicians who are not trained to recognize and diagnose ME/CFS, and who might or might not understand that ME/CFS is a multi-system primarily physical illness. Such misperceptions can adversely affect the doctor-patient relationship, the clinical outcomes, as well as the results of disability claims.

According to the National Academies of Science, Engineering and Medicine, “Between 836,000 and 2.5 million Americans suffer from myalgic encephalomyelitis/chronic fatigue syndrome… This disease is characterized by profound fatigue, cognitive dysfunction, sleep abnormalities, autonomic manifestations, pain, and other symptoms that are made worse by exertion of any sort. ME/CFS can severely impair patients’ ability to conduct their normal lives.1” The prevalence of MECFS among children and adolescents has been estimated variously as between 0.11 and 4% (1). A large percentage of children and adolescents with ME/CFS suffer from orthostatic intolerance due to one or both of these syndromes: Neurally Mediated Hypotension (NMH) and Postural Orthostatic Tachycardia Syndrome (POTS). These elements of ME/CFS often respond well to proper treatment (2, 3).

Mediating Relatedness for Adolescents with ME: Reducing Isolation through Minimal Interactions with a Robot Avatar

Abstract:

This paper discusses how a networked object in the form of a small robot designed to mediate experiences of care, social connectedness, and intimacy, was used by adolescents with Myalgic Encephalomyelitis, a condition that reduces their normal functioning, including the ability to socialize. A study with nine adolescents, each using the robot for about a year in average, revealed that it was largely effective at mediating their everyday experiences of relatedness, triggering productive new habits and social practices. We interpret these findings to propose a set of strategies for designing technologies that support relatedness while requiring minimal interactivity and engagement. Balance, extension-of-self, coolness, and acts-of-care, in addition to commonly used physicalness, expressivity and awareness, enable the robot to extend the adolescents’ ability to relate to others, people and animals.

Physical activity patterns among children and adolescents with mild-to-moderate chronic fatigue syndrome/myalgic encephalomyelitis

Abstract:

OBJECTIVE: Chronic fatigue syndromemyalgic encephalomyelitis (CFS/ME) is relatively common among children and adolescents; however, little is known about the physical activity levels and patterns of this population. The aim of this study was to examine the underlying patterns of physical activity among youth with mild-to-moderate CFS/ME. Cross-sectional associations between physical activity patterns with self-reported physical function, pain, fatigue, anxiety and depression were also examined.

DESIGN: Baseline cross-sectional data from the Managed Activity Graded Exercise iN Teenagers and pre-Adolescents randomised controlled trial.

PATIENTS: Children and adolescents (aged 8-17 years) diagnosed with mild-to-moderate CFS/ME who wore an accelerometer for at least three valid weekdays.

ANALYSES: Latent profile analysis was used to identify physical activity patterns. Linear regression models examined associations between physical activity classes and self-reported physical function, pain, fatigue, anxiety and depression.

RESULTS: 138 children and adolescents (72.5% females) had valid data. Overall, participants did less than half the government recommended level of physical activity for children and adolescents, but not all were inactive: three (2.2%) did more than 1 hour of physical activity every day, and 13 (9.4%) achieved an average of 60 min a day. Adolescents (≥12 years) were less active than younger children, but activity levels were similar between genders. Three latent classes emerged from the data: ‘active’, ‘light’ and ‘inactive’. Compared with being ‘inactive’, being in the ‘light’ class was associated with greater self-reported physical function (10.35, 95% CI 2.32 to 18.38) and lower fatigue (-1.60, 95% CI -3.13 to -0.06), while being ‘active’ was associated with greater physical function (15.26, 95% CI 0.12 to 30.40), but also greater anxiety (13.79, 95% CI 1.73 to 25.85).

CONCLUSIONS: Paediatricians need to be aware that physical activity patterns vary widely before recommending treatment.

Resting-state functional connectivity, cognition, and fatigue in response to cognitive exertion: a novel study in adolescents with chronic fatigue syndrome

Abstract:

Emerging evidence suggests that central nervous system dysfunction may underlie the core symptoms of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) in adults, such as cognitive disturbance, fatigue and post-exertional malaise. Research into brain dysfunction in the pediatric CFS/ME context, however, is severely lacking. It is unclear whether the adolescent CFS/ME brain functions differently compared with healthy peers, particularly in situations where significant mental effort is required. This study used resting-state functional MRI in a novel repeated-measures design to evaluate intrinsic connectivity, cognitive function, and subjective fatigue, before and after a period of cognitive exertion in 48 adolescents (25 CFS/ME, 23 healthy controls).

Results revealed little evidence for a differential effect of cognitive exertion in CFS/ME compared with controls. Both groups demonstrated a similar rate of reduced intrinsic functional connectivity within the default mode network (DMN), reduced sustained attentional performance, slower processing speed, and increased subjective fatigue as a result of cognitive exertion.

However, CFS/ME adolescents consistently displayed higher subjective fatigue, and controls outperformed the CFS/ME group overall on cognitive measures of processing speed, sustained attention and new learning. No brain-behavior relationships were observed between DMN connectivity, cognitive function, and fatigue over time.

These findings suggest that effortful cognitive tasks may elicit similar levels of energy expenditure across all individuals in the form of reduced brain functioning and associated fatigue. However, CFS/ME may confer a lower starting threshold from which to access energy reserves and cognitive resources when cognitive effort is required.

Clinical symptoms and markers of disease mechanisms in adolescent chronic fatigue following Epstein-Barr virus infection: An exploratory cross-sectional study

Abstract:

INTRODUCTION: Acute Epstein-Barr virus (EBV) infection is a trigger of chronic fatigue (CF) and Chronic Fatigue Syndrome (CFS). The aim of this cross-sectional study was to explore clinical symptoms as well as markers of disease mechanisms in fatigued and non-fatigued adolescents 6 months after EBV-infection, and in healthy controls.

MATERIALS AND METHODS: A total of 200 adolescents (12-20 years old) with acute EBV infection were assessed 6 months after the initial infectious event and divided into fatigued (EBV CF+) and non-fatigued (EBV CF-) cases based on questionnaire score. The EBV CF+ cases were further sub-divided according to case definitions of CFS. In addition, a group of 70 healthy controls with similar distribution of sex and age was included. Symptoms were mapped with a questionnaire. Laboratory assays included EBV PCR and serology; detailed blood leukocyte phenotyping and serum high-sensitive C-reactive protein; and plasma and urine cortisol and catecholamines. Assessment of autonomic activity was performed with continuous, non-invasive monitoring of cardiovascular variables during supine rest, controlled breathing and upright standing. Differences between EBV CF+ and EBV CF- were assessed by simple and multiple linear regression adjusting for sex as well as symptoms of depression and anxiety. A p-value ≤ 0.05 was considered statistically significant. This study is part of the CEBA-project (Chronic fatigue following acute Epstein-Barr virus infection in adolescents).

RESULTS: The EBV CF+ group had significantly higher scores for all clinical symptoms. All markers of infection and most immune, neuroendocrine and autonomic markers were similar across the EBV CF+ and EBV CF- group. However, the EBV CF+ group had slightly higher serum C-reactive protein (0.48 vs 0.43 mg/L, p=0.031, high-sensitive assay), total T cell (CD3+) count (median 1573 vs 1481 x 106 cells/L, p=0.012), plasma norepinephrine (1420 vs 1113 pmol/L, p=0.01) and plasma epinephrine (363 vs 237 nmol/L, p=0.032); lower low-frequency:high frequency (LF/HF) ratio of heart rate variability at supine rest (0.63 vs 0.76, p=0.008); and an attenuated decline in LF/HF ratio during controlled breathing (-0.11 vs -0.25, p=0.002). Subgrouping according to different CFS diagnostic criteria did not significantly alter the results. Within the EBV CF+ group, there were no strong correlations between clinical symptoms and markers of disease mechanisms. In a multiple regression analysis, serum CRP levels were independently associated with serum cortisol (B= 4.5 x 10-4, p<0.001), urine norepinephrine (B=9.6 x 10-2, p=0.044) and high-frequency power of heart rate variability (B= -3.7 x 10-2, p=0.024).

CONCLUSIONS: In adolescents, CF and CFS 6 months after acute EBV infection are associated with high symptom burden, but no signs of increased viral load and only subtle alterations of immune, autonomic, and neuroendocrine markers of which no one is strongly correlated with symptom scores. A slight sympathetic over parasympathetic predominance is evident in CF and might explain slightly increased CRP levels.

Fatigue in Epstein-Barr virus infected adolescents and healthy controls: A prospective multifactorial association study

Abstract:

OBJECTIVE: Acute Epstein-Barr virus (EBV) infection is a known trigger of both acute and chronic fatigue. The aim of this study was to investigate associations to fatigue in adolescents with EBV infection during the initial stage and six months after, as well as in healthy controls.

METHODS: 200 adolescents (12-20 years old) with EBV infection were assessed as soon as possible after the onset of symptoms (EBVbaseline) and six months later (EBVsix months, 5 drop-outs). Also, 70 healthy controls (HC) were included. Associations between current fatigue and 148 different variables (including symptoms, functional abilities and biomarkers) were investigated separately for EBVbaseline, EBVsix months and HC using linear regression modelling.

RESULTS: Fatigue was associated with symptoms of sleeping difficulties, negative emotions, and quality of life under all circumstances. Fatigue was independently associated with markers of immune response at EBVsix months and in HC, not at EBVbaseline. An association between fatigue and markers of autonomic cardiovascular control was only present at EBVsix months. Cognitive functioning shifted from a positive association to fatigue at EBVbaseline to a negative trend at EBVsix months. Markers of infection were not associated with fatigue at EBVbaseline, EBVsix months nor in HC.

CONCLUSION: Irrespective of the cause, fatigue is important for quality of life and is highly associated with negative emotions. Markers of infection and immune response had respectively none and barely any association to fatigue. Autonomic alterations and cognitive dysfunction were exclusively associated with fatigue long after infection, corroborating findings from studies of the Chronic Fatigue Syndrome.

Meeting the Educational Needs of Young, ME/CFS Patients: Role of the Treating Physician

Introduction:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disabling, chronic disease characterized by the body’s inability to produce sufficient energy for normal everyday activities. Children with ME/CFS experience debilitating fatigue referred to as post-exertional malaise (PEM) after minimal mental or physical exertion which is not relieved by sleep. It can significantly reduce the ability of the child to take part in personal, educational, or social activities and can compromise executive function, and can result in a moderate to severe disability. As many as 1% of school-age children suffer from this disease in varying degrees of severity, and ME/CFS has been shown to negatively impact school attendance, participation, connectedness, and academic performance (1). Some studies suggest that ME/CFS may be the major cause of extended school absences (2).

Whereas, the literature supplying practice-based guidance for other chronic conditions affecting children in school, such as Autism and Attention Deficit Hyperactivity Disorder (ADHD) will be found in educational journals, very little guidance for students with ME/CFS appears in the clinical medicine literature. Although school nurses are beginning to play a larger role in supporting these children, physicians or healthcare providers retain primary responsibility of informing the school system of the needed adjustments for the young ME/CFS patient to succeed in the school environment.

This article argues that the physician has a much broader responsibility to provide diagnostic, symptomatic, and treatment information about ME/CFS than they would with other conditions such as Autism or ADHD that qualify students for special services. For students with ME/CFS, the physician’s letter required in the school’s evaluation process is a critical resource to advise and guide education professionals regarding appropriate student placement, classroom support, and instructional accommodations or modifications. The specifics of what should be included in a model physician’s letter are included.

EBV-requisitioning physicians’ guess on fatigue state 6 months after acute EBV infection

Abstract:

We assessed referring medical practitioner’s ability to predict chronic fatigue development in adolescents presenting with acute infectious mononucleosis. Compared with ‘not fatigued’ being predicted as ‘unsurely fatigued’ and ‘likely fatigued’ were both strongly associated with developing fatigue 6 months later (OR 2.5, 95% CI 1.16% to 5.47% and 3.2, 95% CI 1.19% to 8.61%, respectively, P=0.012). The positive and negative predictive values were 66% and 62%, respectively. Disentangling the physician’s intuition may be of interest in further investigations of risk factors and prophylactic factors for fatigue development.

Associations Between Autonomic and Orthostatic Self-report and Physician Ratings of Orthostatic Intolerance in Youth

Abstract:

PURPOSE: There is no known biological marker or physical assessment to diagnose chronic fatigue syndrome (CFS), leaving physicians to heavily rely on self-report measures regarding the symptoms associated with CFS. Common symptoms of CFS include difficulty sleeping, joint pain, headaches, sore throat, cognitive dysfunction, physical exhaustion, dizziness, and nausea. Because of the overlap among CFS symptoms and autonomic functioning, we examined the association between 2 self-report measures of orthostatic and autonomic symptoms and a physician’s report of autonomic functioning (measures of changes in blood pressure and pulse) to further understand the association among autonomic functioning within individuals with symptoms of CFS.

METHODS: With data from an ongoing study, we used independent t tests and Pearson correlation tests to assess the association among the orthostatic domain from the DePaul Symptom Questionnaire, Autonomic Symptom Checklist composite scores, and the physician’s assessment of orthostatic intolerance obtained from a sample of 191 participants, 42 who were healthy controls.

FINDINGS: No significant demographic differences were found between the CFS-like group and the healthy controls. Results indicate a significant correlation between orthostatic and autonomic functioning (r = 0.58) and a correlation with a low effect size among autonomic functioning and physician measures of orthostatic functioning (r = -0.01 to 0.29). However, fewer correlations were found between self-reported symptoms of orthostatic functioning and the physician’s measures of orthostatic functioning.

IMPLICATIONS: These results suggest that although orthostatic dysfunction is reported in children and adolescents with CFS-like symptoms, the physical measures of autonomic functioning in this study were unable to detect these symptoms.

Long Term Follow up of Young People With Chronic Fatigue Syndrome Attending a Pediatric Outpatient Service

Abstract:

Aim: To determine the reported duration of illness, the functional and educational long-term outcomes, predictive factors for recovery and seek feedback regarding management in pediatric/adolescent myalgic encepahalomyelitis/chronic fatigue syndrome (ME/CFS).

Methods: A cohort observational study of 784 young people, mean age 14.6 (6-18) years, with ME/CFS diagnosed at a specialist pediatric hospital and receiving regular care, was conducted with follow-up for a mean 8 (range 1-21) years after onset. Baseline symptoms, history, depression and anxiety questionnaires were available from 418. The remaining 366, did not have similar standardized baseline information. Questionnaires requested functional rating, persistent symptoms, duration of illness if “recovered,” social engagement and school/work attendance. Feedback was sought regarding management, support services, useful information, helpful interventions or personnel and use of alternative therapies. Reported recovery and function were compared with baseline information and between the two groups.

Results: Follow-up data were returned from 81.8%. There was no significant difference in functional score (if reported recovery) or illness duration related to provision of baseline data. The mean duration of illness was 5 (range 1-15) years in the 50% who reported recovery. By 5 years 38% and by 10 years 68% reported recovery. At 10 years the mean functional score was 8/10 (range 2-10) with 5% scoring <6. Depression, anxiety or severity of illness at diagnosis was not predictive of non-recovery. Designing and monitoring their own management plan that included educational, social, physical and enjoyable activities, as well as having symptom management and understanding professionals were highly valued. However, remaining engaged in an education system that flexibly accommodated their illness and aspirations was consistently reported as crucial for long term functioning.

Conclusions: ME/CFS in young people has a mean duration of 5 years (1-15) with 68% reporting recovery by 10 years. All improved functionally with 5% remaining very unwell and a further 20% significantly unwell. There were no obvious baseline predictors for recovery. However, depression, anxiety, orthostatic intolerance and to a lesser extent pain at follow up were identified as hampering recovery or function. Supportive professionals, remaining engaged in education and management strategies were identified as helpful.
