Serial Paediatrics Omics Tracking in Myalgic Encephalomyelitis (SPOT-ME): protocol paper for a multidisciplinary, observational study of clinical and biological markers of paediatric myalgic encephalomyelitis/chronic fatigue syndrome in Australian adolescents aged 12-19 years

Abstract:

Introduction: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling condition that can affect adolescents during a vulnerable period of development. The underlying biological mechanisms for ME/CFS remain unclear and have rarely been investigated in the adolescent population, despite this period representing an age peak in the overall incidence. The primary objective of this is to provide a foundational set of biological data on adolescent ME/CFS patients. Data generated will be compared with controls and over several time points within each patient to potentially develop a biomarker signature of the disease, identify subsets or clusters of patients, and to unveil the pathomechanisms of the disease.

Methods and analysis: This protocol paper outlines a comprehensive, multilevel, longitudinal, observational study in paediatric ME/CFS. ME/CFS patients aged 12-19 years and controls will donate biosamples of urine, blood, and peripheral blood mononuclear cells for an in-depth omics profiling analysis (whole-genome sequencing, metabolomics and quantitative proteomics) while being assessed by gold-standard clinical and neuropsychological measures. ME/CFS patients will then be provided with a take-home kit that enables them to collect urine and blood microsamples during an average day and during days when they are experiencing postexertional malaise. The longitudinal repeated-measures study design is optimal for studying heterogeneous chronic diseases like ME/CFS as it can detect subtle changes, control for individual differences, enhance precision and boost statistical power. The outcomes of this research have the potential to identify biomarker signatures, aid in understanding the underlying mechanisms, and ultimately, improve the lives of children with ME/CFS.

Ethics and dissemination: This project was approved by the Royal Children’s Hospital’s Human Research Ethics Committee (HREC 74175). Findings from this study will be disseminated through peer-reviewed journal publications and presentations at relevant conferences. All participants will be provided with a summary of the study’s findings once the project is completed.

Development and Implementation of an Online Patient Education Program for Children and Adolescents With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, Their Parents, Siblings, and School Personnel: Protocol for the Prospective BAYNET FOR ME/CFS Study

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) presents significant challenges for affected children and adolescents, their social environment, and treating physicians, due to its profound impact on quality of life and the lack of causal therapeutic approaches. One crucial aspect of care that has been missing for these patients is comprehensive education for both them and their social circles.

Objective: This study protocol aims to outline the goals, study design, execution, and evaluation of the subproject within the BAYNET FOR ME/CFS project. The focus is on developing online education programs for children and adolescents with ME/CFS, as well as for their parents, siblings, and school staff. These programs are designed to improve independent disease management, increase knowledge, and promote interaction with other affected individuals.

Methods: In phase I, the group-based online education programs were developed by a multidisciplinary team based on the ModuS concept created by the Competence Network for Patient Education (KomPaS). These programs were then piloted and finalized. Phase II involved recruiting participants and implementing the finalized programs. Given the restricted physical and cognitive capacities of the affected individuals, the patient education programs were exclusively designed in a digital format to facilitate participation. In phase III, the programs will be evaluated for acceptance, completeness, and participant satisfaction. The qualitative assessment will focus on individual expectations and benefits derived from the training. Phase IV will further assess the programs in terms of improvements in disease knowledge, health-related quality of life, life satisfaction, and family burden.

Results: The programs were developed, piloted, and finalized during phase I, which ran from December 2022 to May 2023. The pilot phase, from March to May 2023, led to adaptations in the program concept. In total, 8 patients and their parents, 5 siblings, and 59 school staff participated in the piloting. Adjustments were made to the format, content, duration, and schedule to better meet the needs of the affected individuals and their social circles. In phase II, participant recruitment for the patient education program took place from January to July 2023. The study successfully recruited 24 young patients with ME/CFS and their parents, along with 8 siblings and 51 school staff. Two program blocks for patients and parents and 2-3 blocks for siblings and school staff commenced in May 2023 and were completed within the same year. Phase III began after phase II and involves the evaluation of the programs, with the process expected to conclude by the end of 2024. Phase IV, planned for 2025-2026, will involve the rollout of the program to 150 children and their caretakers. This phase will focus on evaluating disease knowledge, health-related quality of life, life satisfaction, and family burden, as well as include longitudinal assessments.

Conclusions: The data aim to support the development of a comprehensive, interprofessional care model for children and adolescents with ME/CFS.

Management of severe ME/CFS in children and young people in the UK: a British Paediatric Surveillance Unit study

Abstract:

Objective: Severe myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS) in children and young people (CYP) is a little-understood condition which significantly impacts education, development and quality of life. We used data from a population-wide surveillance study to explore the screening investigation, referral and management of suspected cases of paediatric severe ME/CFS.

Methods: A British Paediatric Surveillance Unit (BPSU) study reported cases of CYP with suspected severe ME/CFS between February 2018 and February 2019. Paediatricians reporting cases to BPSU and allied healthcare professionals in two large specialist paediatric ME/CFS centres were invited to complete questionnaires for CYP meeting the surveillance case definition. The study focused primarily on CYP with confirmed severe ME/CFS and the extent to which their care met NICE (The National Institute for Health and Care Excellence) recommendations but also considered separately those with probable or possible severe ME/CFS.

Results: This study includes a total of 92 CYP with suspected severe ME/CFS; 33 meeting criteria for severe ME/CFS and an additional 59 classified as probable or possible severe ME/CFS. For 16 possible cases, incomplete investigation to exclude alternative diagnoses prevented confirmation of a severe ME/CFS diagnosis. Only 21 of 33 (64%) confirmed severe ME/CFS cases had been referred to specialist services. The management provided varied considerably between patients and four received nothing at all. Of the management provided, the most frequent approaches were medication (67%), activity management (61%) and physiotherapy (61%). Domiciliary assessments and support, and social services referrals were received by 12% and 6% of confirmed severe cases. Similar proportions of management approaches were seen in probable/possible severe ME/CFS.

Conclusion: Full investigation is frequently incomplete in CYP with suspected severe ME/CFS and recommendations for referral and management are poorly implemented, in particular the needs of CYP who are unable to leave their home might be poorly met.

Graded exercise therapy compared to activity management for paediatric chronic fatigue syndrome/myalgic encephalomyelitis: pragmatic randomized controlled trial

Abstract

The MAGENTA pragmatic parallel groups randomized controlled trial compared graded exercise therapy (GET) with activity management (AM) in treating paediatric myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). Children aged 8-17 years with mild/moderate ME/CFS and presenting to NHS specialist paediatric services were allocated at random to either individualised flexible treatment focussing on physical activity (GET, 123 participants) or on managing cognitive, school and social activity (AM, 118 participants) delivered by NHS therapists.

The primary outcome was the self-reported short-form 36 physical function subscale (SF-36-PFS) after 6 months, with higher scores indicating better functioning. After 6 months, data were available for 201 (83%) participants who received a mean of 3.9 (GET) or 4.6 (AM) treatment sessions. Comparing participants with measured outcomes in their allocated groups, the mean SF-36-PFS score changed from 54.8 (standard deviation 23.7) to 55.7 (23.3) for GET and from 55.5 (23.1) to 57.7 (26.0) for AM giving an adjusted difference in means of -2.02 (95% confidence interval -7.75, 2.70). One hundred thirty-five participants completed the mean SF-36-PFS at 12 months, and whilst further improvement was observed, the difference between the study groups remained consistent with chance.

The two study groups showed similar changes on most of the secondary outcome measures: Chalder Fatigue, Hospital Anxiety and Depression Scale: Depression, proportion of full-time school attended, a visual analogue pain scale, participant-rated change and accelerometer measured physical activity, whether at the 6-month or 12-month assessment.

There was an isolated finding of some evidence of an improvement in anxiety in those allocated to GET, as measured by the Hospital Anxiety and Depression Scale at 6 months, with the 12-month assessment, and the Spence Children’s Anxiety scale being aligned with that finding. There was weak evidence of a greater risk of deterioration with GET (27%) than with AM (17%; p = 0.069).

At conventional UK cost per QALY thresholds, the probability that GET is more cost-effective than AM ranged from 18 to 21%. Whilst completion of the SF-36-PFS, Chalder Fatigue Scale and EQ-5D-Y was good at the 6-month assessment point, it was less satisfactory for other measures, and for all measures at the 12-month assessment.

Conclusion: There was no evidence that GET was more effective or cost-effective than AM in this setting, with very limited improvement in either study group evident by the 6-month or 12-month assessment points.

A suffering body, hidden away from others: The experience of being long-term bedridden with severe myalgic encephalomyelitis/chronic fatigue syndrome in childhood and adolescence

Abstract:

In this article, we present findings from a qualitative study examining how young women experience being long-term bedridden with myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), during childhood and adolescence. The aim is to explore how young women who fell ill with ME/CFS during childhood and adolescence look back on their lived experience of being long-term bedridden from the vantage point of being fully or partially recovered.

Informed by a phenomenological theoretical perspective, the researchers applied a narrative methodological approach involving the analysis of interviews with 13 women, aged 16–29 years at the time of the interview. Attention was particularly paid to how participants structured their narratives and to the events (telling moments) they identified as important.

Four major storylines were developed: Ambivalent responses to the presence of others; A body on the edge of life; An eternity in the dark; and Recasting painful memories of being bedridden and alone.

Based on our findings, we argue that the experience of being long-term bedridden with ME/CFS during childhood and adolescence can be understood and communicated as a plot in which individuals find themselves pushed to the extreme limit of suffering and loneliness.

A qualitative study to explore children’s experience of having long-Covid

There is currently uncertainty and limited research surrounding long-COVID in the paediatric population. Reports are conflicting regarding the prevalence, duration, and impact of long COVID on children. Despite the limited evidence, it is becoming increasingly apparent that numerous children are experiencing long-term physical and psychological effects of COVID19 many months after the initial infection. This thesis aimed to investigate the lived experience of children with long-COVID.
Part one of this portfolio presents a systematic review of the experiences of parents who provide care for a child with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The findings of the review indicate a paucity of research on parents’ experiences. However, it is apparent that caring for a child with ME/CFS is an all-encompassing, relentless undertaking, which can detrimentally impact parents’ well-being, everyday life, and relationships.
Given both ME/CFS and long-COVID are both post-viral illnesses, sharing similar symptoms, with low-level immune system activation. It may be conjectured that the existing knowledge on children with ME/CFS could benefit both children suffering from long-COVID and help inform parents on how best to care for their children.
Part two of this portfolio presents an empirical paper exploring the lived-experience of young people with long-COVID. Reflexive thematic analysis found three key themes, specifically, the perceived barriers to coping with long-COVID, ongoing associated emotional distress, and a desire for an integrated approach to long-COVID care.

Pediatric and Adult Patients with ME/CFS following COVID-19: A Structured Approach to Diagnosis Using the Munich Berlin Symptom Questionnaire (MBSQ)

Abstract:

Purpose A subset of patients with post-COVID-19 condition (PCC) fulfill the clinical criteria of myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS). To establish the diagnosis of ME/CFS for clinical and research purposes, comprehensive scores have to be evaluated.

Methods We developed the Munich Berlin Symptom Questionnaires (MBSQs) and supplementary scoring sheets (SSSs) to allow for a rapid evaluation of common ME/CFS case definitions. The MBSQs were applied to young patients with chronic fatigue and post-exertional malaise (PEM) who presented to the MRI Chronic Fatigue Center for Young People (MCFC). Trials were retrospectively registered (NCT05778006, NCT05638724).

Results Using the MBSQs and SSSs, we report on ten patients aged 11 to 25 years diagnosed with ME/CFS after asymptomatic SARS-CoV-2 infection or mild to moderate COVID-19. Results from their MBSQs and from well-established patient-reported outcome measures indicated severe impairments of daily activities and health-related quality of life.

Conclusions ME/CFS can follow SARS-CoV-2 infection in patients younger than 18 years, rendering structured diagnostic approaches most relevant for pediatric PCC clinics. The MBSQs and SSSs represent novel diagnostic tools that can facilitate the diagnosis of ME/CFS in children, adolescents, and adults with PCC and other post-viral syndromes.

What is known ME/CFS is a frequent debilitating illness. For diagnosis, an extensive differential diagnostic workup is required and the evaluation of clinical ME/CFS criteria. ME/CFS following COVID-19 has been reported in adults but not in pediatric patients younger than 19 years of age.

What is new We present novel questionnairs (MBSQs), as tools to assess common ME/CFS case definitions in pediatric and adult patients with post-COVID-19 condition and beyond. We report on ten patients aged 11 to 25 years diagnosed with ME/CFS following asymptomatic SARS-CoV-2 infection or mild to moderate COVID-19.

One-Year Follow-up of Young People with ME/CFS Following Infectious Mononucleosis by Epstein-Barr Virus

Abstract:

Background: Infectious mononucleosis, caused by the Epstein-Barr Virus (EBV-IM), has been linked to the development of myalgic encephalomyelitis/chronic fatigue-syndrome (ME/CFS) in children, adolescents, and young adults. Our study presents the first cohort of young individuals in Germany who were diagnosed with ME/CFS following EBV-IM.

Methods: We conducted a one-year follow-up of 25 young people diagnosed with ME/CFS at our specialized tertiary outpatient service by clinical criteria requiring post-exertional malaise and with documented EBV-IM as the triggering event. Demographic information, laboratory findings, frequency and severity of symptoms, physical functioning, and health-related quality of life (HRQoL) were assessed at first visit as well as 6 and 12 months later at follow-up visits.

Results: The physical functioning and HRQoL of the cohort were significantly impaired, with young adults displaying more severe symptoms, as well as worsening of fatigue, physical and mental functioning, and HRQoL throughout the study, compared to adolescents. After one year, we found that 6/12 (54%) adolescents no longer met the diagnostic criteria for ME/CFS, indicating partial remission, while all young adults continued to fulfill the Canadian consensus criteria. Improvement in children was evident in physical functioning, symptom frequency and severity, and HRQoL, while young adults had little improvement. EBV serology and EBV DNA load did not correlate with distinct clinical features of ME/CFS, and clinical chemistry showed no evidence of inflammation. Remarkably, the median time from symptom onset to ME/CFS diagnosis was 13.8 (IQR: 9.1-34.9) months.

Conclusions: ME/CFS following EBV-IM in young people is a severely debilitating disease with diagnoses protracted longer than one year in many patients and only limited responses to conventional symptom-oriented medical care. Although younger children may have a better prognosis, their condition can fluctuate and significantly impact their HRQoL. Our data emphasize that biomarkers and effective therapeutic options are also urgently needed for this very young age group to better manage their medical condition and pave the way to recovery.

What lies beneath: White matter microstructure in pediatric myalgic encephalomyelitis/chronic fatigue syndrome using diffusion MRI

Abstract:

Recent studies in adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) suggest that changes in brain white matter microstructural organization may correlate with core ME/CFS symptoms, and represent a potential biomarker of disease. However, this has yet to be investigated in the pediatric ME/CFS population. We examined group differences in macrostructural and microstructural white matter properties, and their relationship with clinical measures, between adolescents recently diagnosed with ME/CFS and healthy controls.

Forty-eight adolescents (25 ME/CFS, 23 controls, mean age 16 years) underwent brain diffusion MRI, and a robust multi-analytic approach was used to evaluate white and gray matter volume, regional brain volume, cortical thickness, fractional anisotropy, mean/axial/radial diffusivity, neurite dispersion and density, fiber density, and fiber cross section.

From a clinical perspective, adolescents with ME/CFS showed greater fatigue and pain, poorer sleep quality, and poorer performance on cognitive measures of processing speed and sustained attention compared with controls. However, no significant group differences in white matter properties were observed, with the exception of greater white matter fiber cross section of the left inferior longitudinal fasciculus in the ME/CFS group compared with controls, which did not survive correction for intracranial volume.

Overall, our findings suggest that white matter abnormalities may not be predominant in pediatric ME/CFS in the early stages following diagnosis. The discrepancy between our null findings and white matter abnormalities identified in the adult ME/CFS literature could suggest that older age and/or longer illness duration influence changes in brain structure and brain-behavior relationships that are not yet established in adolescence.

Comparison of a 20 degree and 70 degree tilt test in adolescent myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) patients

Abstract:

Introduction: During a standard 70-degree head-up tilt test, 90% of adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) develop an abnormal reduction in cerebral blood flow (CBF). A 70-degree test might not be tolerated by young ME/CFS patients because of the high incidence of syncopal spells. This study examined whether a test at 20 degrees would be sufficient to provoke important reductions in CBF in young ME/CFS patients.

Methods: We analyzed 83 studies of adolescent ME/CFS patients. We assessed CBF using extracranial Doppler measurements of the internal carotid and vertebral arteries supine and during the tilt. We studied 42 adolescents during a 20 degree and 41 during a 70 degree test.

Results: At 20 degrees, no patients developed postural orthostatic tachycardia (POTS), compared to 32% at 70 degrees (p = 0.0002). The CBF reduction during the 20 degree tilt of -27(6)% was slightly less than during the reduction during a 70 degree test [-31(7)%; p = 0.003]. Seventeen adolescents had CBF measurements at both 20 and 70 degrees. The CBF reduction in these patients with both a 20 and 70 degrees test was significantly larger at 70 degrees than at 20 degrees (p < 0.0001).

Conclusions: A 20 degree tilt in young ME/CFS patients resulted in a CBF reduction comparable to that in adult patients during a 70 degree test. The lower tilt angle provoked less POTS, emphasizing the importance of using the 70 degree angle for that diagnosis. Further study is needed to explore whether CBF measurements during tilt provide an improved standard for classifying orthostatic intolerance.
