Severe myalgic encephalomyelitis/chronic fatigue syndrome in children and young people: a British Paediatric Surveillance Unit study

Abstract:

Objectives: Primary objective: to determine the point prevalence and incidence rate of severe myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in children aged 5-16 years over 13 months.

Secondary objectives: to describe the demographic features, symptoms, impact on activities of daily living, school attendance and time to diagnosis.

Design: Prospective surveillance study conducted by the British Paediatric Surveillance Unit. Paediatricians was asked if they had assessed a child with severe ME/CFS (screening definition for prevalence and incidence: children (5-16 years) diagnosed with ME/CFS so severe that they are unable to attend school for more than 1 hour a week during the last 6 weeks of the school term).

Participants: Patients 5-16 years of age, seen by paediatricians and two large ME/CFS specialist services across the UK and Ireland.

Outcome measures: Paediatrician-completed questionnaires describing demographics, symptoms, function and treatment, (applying National Institute for Health and Care Excellence (NICE)-recommended criteria to assess severity of ME/CFS). Diagnosis of severe, probable severe or possible severe ME/CFS was made only with evidence of NICE-recommended screening blood tests.

Results: 285 cases were reported, of which of which 33 were severe, 4 probable severe and 55 possible severe. Estimated prevalence was 3.2 per million children (95% CI 2.2 to 4.5). Including possible/probable severe ME/CFS gave 8.9 per million children (95% CI 7.2 to 11). The incidence rate was 0.90 per million children-years (95% CI 0.43 to 1.65) (1.97 per million children-years (95% CI 1.24 to 2.99)). Median age was 13 years and 58% of cases were female. Median time to diagnosis was 0.47 years.

Conclusions: Although the incidence of children presenting with severe ME/CFS is low, all were very disabled. In addition, the majority receive little or no education. Paediatricians need to consider how to provide rehabilitation and education for these disabled young people.

The fragile process of Homecoming – Young women in recovery from severe ME/CFS

Abstract:

Purpose: To explore the recovery narratives of 13 young women who had fallen ill with severe Myalgic Encephalomyelitis (ME), also known as Chronic Fatigue Syndrome (CFS), during childhood and adolescence, with the focus on what they had to say about their past experiences from the perspective of the present.

Method: A qualitative narrative approach, informed by a phenomenological theoretical perspective, was adopted to explore what the women found significant and meaningful in their recovery process. Data analysis of in-depth narrative interviews was performed which are presented to readers through the stories of two particular participants.

Results: The first story describes how one participant made a recovery by testing her body’s tolerance and working to create a more confident self. The second story describes a complex exploration of possibilities for action in recovery, along with a struggle to make sense of setbacks and hold on to what has been gained.

Conclusion: Recovering from ME/CFS emerges as an inter-personal, contextual, fragile and nonlinear process of homecoming, based on gradually rising bodily based self-knowledge. Illness slowly fades away into the background, and there is the prospect of a healthier tomorrow.

Experiences of carers of youth, adult children and spouses with ME/CFS

Abstract:

Objectives: The debilitating nature of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) means that family members often take on a caring role. This study compared the experiences of people caring for three groups: youth, young adults, spouses.

Methods: An opportunistic sample of 36 carers completed an online survey of open-ended questions asking about their experiences. Thematic analysis was used to consider the three sets of responses separately and Thematic Comparison was used to identify points of connection and disconnection across the sets.

Results: The themes identified were very similar to those identified in past studies. Two super-ordinate themes were identified: “Lack of knowledge and understanding” and “Holistic Impact”. Though most sub-ordinate themes were evident across all three groups, important differences were found. The sub-ordinate themes “Caring Blindly”, “Emotional and physical health cost”, and “Impact on the whole family” were more evident amongst carers of youth while the theme “Worry for the future” was more evident from carers of young adults and spouses.

Discussion: Differences seemed to be related to both the time since diagnosis and the life stage. A longitudinal study would help to understand how carer experiences change over the life course of caring for someone with ME/CFS.

Association of SARS-CoV-2 Seropositivity With Myalgic Encephalomyelitis and/or Chronic Fatigue Syndrome Among Children and Adolescents in Germany

Abstract:

Importance: During the COVID-19 pandemic, a reduction in quality of life and physical and mental health among children and adolescents has been reported that may be associated with SARS-CoV-2 infection and/or containment measures.

Objective: To assess the association of SARS-CoV-2 seropositivity with symptoms that may be related to myalgic encephalomyelitis and/or chronic fatigue syndrome (ME/CFS) among children and adolescents.

Design, setting, and participants: This substudy of the cross-sectional SARS-CoV-2 seroprevalence surveys in Germany (SARS-CoV-2 KIDS) was performed in 9 pediatric hospitals from May 1 to October 31, 2021. Pediatric patients were recruited during an inpatient or outpatient visit regardless of the purpose of the visit. Parental questionnaires and serum samples were collected during clinically indicated blood draws. The parental questionnaire on demographic and clinical information was extended by items according to the DePaul Symptom Questionnaire, a pediatric screening tool for ME/CFS in epidemiological studies in patients aged 5 to 17 years.

Exposures: Seropositivity was determined by SARS-CoV-2 IgG antibodies in serum samples using enzyme-linked immunosorbent assays.

Main outcomes and measures: Key symptoms of ME/CFS were evaluated separately or as clustered ME/CFS symptoms according to the DePaul Symptom Questionnaire, including fatigue.

Results: Among 634 participants (294 male [46.4%] and 340 female [53.6%]; median age, 11.5 [IQR, 8-14] years), 198 (31.2%) reported clustered ME/CFS symptoms, including 40 of 100 SARS-CoV-2-seropositive (40.0%) and 158 of 534 SARS-CoV-2-seronegative (29.6%) children and adolescents. After adjustment for sex, age group, and preexisting disease, the risk ratio for reporting clustered ME/CFS symptoms decreased from 1.35 (95% CI, 1.03-1.78) to 1.18 (95% CI, 0.90-1.53) and for substantial fatigue from 2.45 (95% CI, 1.24-4.84) to 2.08 (95% CI, 1.05-4.13). Confinement to children and adolescents with unknown previous SARS-CoV-2 infection status (n = 610) yielded lower adjusted risks for all symptoms except joint pain ME/CFS-related symptoms. The adjusted risk ratio was 1.08 (95% CI, 0.80-1.46) for reporting clustered ME/CFS symptoms and 1.43 (95% CI, 0.63-3.23) for fatigue.

Conclusions and relevance: These findings suggest that the risk of ME/CFS in children and adolescents owing to SARS-CoV-2 infection may be very small. Recall bias may contribute to risk estimates of long COVID-19 symptoms in children. Extensive lockdowns must be considered as an alternative explanation for complex unspecific symptoms during the COVID-19 pandemic.

Experiences of pain in paediatric chronic fatigue syndrome/myalgic encephalomyelitis: a single-centre qualitative study

Abstract:

Background: Moderate to severe pain affects up to two-thirds of children with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and is associated with worse fatigue and physical functioning. This research aims to gain a greater insight into pain experienced by these children.

Methods: Thematic analysis of qualitative data from semistructured interviews with 13 children with CFS/ME (mean age=15.3 years, 67% female) was completed.

Results: Thematic analysis enabled construction of three themes: children’s wide-ranging experiences of pain, negative impact of pain and lack of effective treatment for pain and nine subthemes. The first theme demonstrated highly varied pain experiences, ranging from ‘like [being]… on fire’, like ‘being stabbed’ to ‘like…lead’. Children experienced pain in multiple sites and with wide-ranging frequency and severity. The second theme highlighted the profound negative impact of pain on multiple aspects of children’s lives. Physical activity was severely impaired; some children ‘couldn’t leave bed’ or ‘couldn’t…brush [their] own hair’. Abdominal pain meant some would ‘go…days without eating’. Pain substantially impacted on mental health, leaving children feeling ‘agitated’, experiencing ‘really bad panic attacks’ or making them ‘[want to] breakdown’. Children felt they ‘can’t do the things that everyone else can do’, had ‘missed out’ and are ‘behind everyone’. Some avoided socialising as they ‘don’t want to stop everyone else’. The final theme demonstrates the absence of adequate treatment for pain, with participants reporting ‘nothing has ever really got rid of it’ and only ‘slightly [takes] the edge off’ and other experiencing side effects.

Conclusions: Pain in paediatric CFS/ME is highly variable, common and often results in severe physical limitation and poor mental health. Effective treatments for pain represent an unmet need.

The importance of school in the management of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): issues identified by adolescents and their families

Abstract:

Paediatric Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) is a disabling condition. Schools play a key role in adolescents’ experiences with managing ME/CFS. However, little is known about the experiences of adolescents with ME/CFS (and their families) in schools.

This paper is an incidental qualitative study, which combines data from two independent ME/CFS studies: study 1 researched ethnic minority adolescents with ME/CFS; study 2 explored Acceptance and Commitment Therapy for adolescents with ME/CFS who had not recovered after one year. Participants included: adolescents with ME/CFS; their families; and medical professionals (ME/CFS specialists and non-specialists). Adolescents, their families, and ME/CFS medical professionals were recruited from a UK specialist paediatric ME/CFS service. Non-ME/CFS medical professionals were recruited from the same region.

Semi-structured qualitative interviews and focus groups were undertaken. Participants’ views on schools from each study were combined and thematic analysis was used to identify themes. Fifteen adolescents with ME/CFS (11-17 years old), sixteen family members, and ten medical professionals (GPs, school nurses and ME/CFS specialists) were interviewed.

Four key themes were found: (1) adolescents identified school was important for aiding ME/CFS recovery, especially educationally and socially; (2) families described varying levels of support from schools and local authorities with help managing ME/CFS – some described significant practical and emotional difficulties to accessing education, whereas others recounted examples of positive supportive strategies, particularly when teachers had previous experience or knowledge of ME/CFS; (3) parents thought three-way communication between schools, healthcare and families could improve support; (4) participants felt schools were an appropriate place for knowledge building and raising awareness of ME/CFS amongst teachers and pupils, to aid improved supportive measures.

In conclusion, this paper provides rich data that highlights the importance of education and the realistic fears and hurdles for adolescents with ME/CFS remaining engaged in education and the impact on their future. Some families described positive strategies in school, which were viewed as helpful to manage ME/CFS in the classroom. These strategies could be implemented alongside knowledge building initiatives and improved communication between healthcare and education. There is a need to further investigate useful strategies and determine how teachers can be best supported in implementing them.

Identifying disrupted biological factors and patient-tailored interventions for chronic fatigue in adolescents and young adults with Q-Fever Fatigue Syndrome, Chronic Fatigue Syndrome and Juvenile Idiopathic Arthritis (QFS-study): study protocol for a randomized controlled trial with single-subject experimental case series design

Abstract:

Background: Chronic fatigue with a debilitating effect on daily life is a frequently reported symptom among adolescents and young adults with a history of Q-fever infection (QFS). Persisting fatigue after infection may have a biological origin with psychological and social factors contributing to the disease phenotype. This is consistent with the biopsychosocial framework, which considers fatigue to be the result of a complex interaction between biological, psychological, and social factors. In line, similar manifestations of chronic fatigue are observed in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and juvenile idiopathic arthritis (JIA). Cognitive behavioral therapy is often recommended as treatment for chronic fatigue, considering its effectiveness on the group level. However, not everybody benefits on the individual level. More treatment success at the individual level might be achieved with patient-tailored treatments that incorporate the biopsychosocial framework.

Methods: In addition to biological assessments of blood, stool, saliva, and hair, the QFS-study consists of a randomized controlled trial (RCT) in which a single-subject experimental case series (N=1) design will be implemented using Experience Sampling Methodology in fatigued adolescents and young adults with QFS, CFS/ME, and JIA (aged 12-29). With the RCT design, the effectiveness of patient-tailored PROfeel lifestyle advices will be compared against generic dietary advices in reducing fatigue severity at the group level. Pre-post analyses will be conducted to determine relevance of intervention order. By means of the N=1 design, effectiveness of both advices will be measured at the individual level.

Discussion: The QFS-study is a comprehensive study exploring disrupted biological factors and patient-tailored lifestyle advices as intervention in adolescent and young adults with QFS and similar manifestations of chronic fatigue. Practical or operational issues are expected during the study, but can be overcome through innovative study design, statistical approaches, and recruitment strategies. Ultimately, the study aims to contribute to biological research and (personalized) treatment in QFS and similar manifestations of chronic fatigue.

Cytokine network analysis in a community-based pediatric sample of patients with myalgic encephalomyelitis/chronic fatigue syndrome

Abstract:

Objectives: Studies have demonstrated immune dysfunction in adolescents with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS); however, evidence is varied. The current study used network analysis to examine relationships between cytokines among a sample of pediatric participants with ME/CFS.

Methods: 10,119 youth aged 5-17 in the Chicagoland area were screened for ME/CFS; 111 subjects and controls were brought in for a physician examination and completed a blood draw. Youth were classified as controls (Cs, N = 43), ME/CFS (N = 23) or severe (S-ME/CFS, N = 45). Patterns of plasma cytokine networks were analyzed.

Results: All participant groups displayed a primary network of interconnected cytokines. In the ME/CFS group, inflammatory cytokines IL-12p70, IL-17A, and IFN-γ were connected and included in the primary membership, suggesting activation of inflammatory mechanisms. The S-ME/CFS group demonstrated a strong relationship between IL-17A and IL-23, a connection associated with chronic inflammation. The relationships of IL-6 and IL-8 in ME/CFS and S-ME/CFS participants also differed from Cs. Together, these results indicate pro-inflammatory responses in our illness populations.

Discussion: Our data imply biological differences between our three participant groups, with ME/CFS and S-ME/CFS participants demonstrating an inflammatory profile. Examining co-expression of cytokines may aid in the identification of a biomarker for pediatric ME/CFS.

Health-related quality of life in Young People with Chronic fatigue syndrome/ Myalgic encephalomyelitis

Abstract

Background: Chronic fatigue syndrome/Myalgic encephalomyelitis (CFS/ME) is a disease that affects people of all ages. CFS/ME significantly limits the activity level of those affected, including in relation to physical activity, schooling, occupational life and social life.

High levels of school absence among young people with CFS/ME result in loss of important learning and social development among peers. As such, there is increasing uncertainty about their future, and personal and socio-economic consequences could put them at risk of becoming disabled at a young age. Measurements of health-related quality of life (HRQoL), including being able to function in school, have shown that young people with CFS/ME score lower than their counterparts without CFS/ME.

Aims: The overall aim of this project was to explore HRQoL among young people with CFS/ME, including the factors associated with HRQoL in relation to school and everyday life.

More specifically, the aim was to firstly (Study1) examine HRQoL, including factors that are positively or negatively associated with HRQoL, in a cohort of young people with CFS/ME.

Study 1, along with the previous literature, provided the basis for an in-depth study (Study 2) to investigate the positive and negative factors that young people with CFS/ME experience in school and everyday life.

Based on the findings from Study 1 and Study 2, a third study (Study 3) was planned to explore teachers’, counsellors’ and school nurses’ experiences with educational and social adaptation at school for young people with CFS/ME.

Method: To explore HRQoL and the factors associated with HRQoL among young people with CFS/ME (Studies 1 & 2), a cross-sectional survey- and interview-based study was conducted. The participants of the cross-sectional study were recruited to participate in the interview study.

To explore the experiences of teachers, counsellors and school nurses with education and social adaptions at school for young people with CFS/ME (Study 3), an interview study was conducted with participants recruited among school personnel and school nurses in secondary school (educating students aged 13-16), high school (educating students aged 16-19) and educational psychological services (EPS).

Results: A total of 63 participants were included in the cross-sectional study, 18 of whom participated in the interview study. A total of 12 participants were included in the interview study with the teachers, counsellors and school nurses. In the cross-sectional study (Study 1), young people with CFS/ME scored lower on HRQoL than their counterparts who were healthy or had other chronic diseases. Contact with school and teachers was associated with a higher HRQoL among young people with CFS/ME.

This association could be due to that more contact resulted from adaptations of education and social life at school, or that fewer health problems due to CFS/ME had abled the young people to maintain the contact with school and teachers.

In Study 2, it was found that an adapted plan for education and social life at school for young people with CFS/ME could increase the possibility of continuing schooling with peers. The lack of an adapted plan for education and social life at school could lead to increased school absence as well as loss of education, social contact and development among peers. Subsequently, this could lead to depressive thoughts and worry about the future.

The school personnel and school nurses in Study 3 experienced that young people with CFS/ME lost confidence in school. The challenges experienced by school personnel included (1) understanding students’ needs before they received a diagnosis and before school personnel received information from healthcare providers and (2) maintaining the teacher–student relationship and (3) the continuity of teaching.

In terms of measures for better management, early problematization of school absence, interdisciplinary collaboration on early measures, ensuring the maintenance of the teacher–student relationship and increasing CFS/ME-related competence in schools were proposed. These measures could contribute to prevent loss of function and school absence among young people with CFS/ME.

Conclusion: HRQoL among young people with CFS/ME was associated with contact with school and teachers, but a causal relationship could not be proven.

Interviews with young people with CFS/ME and school personnel suggested that interdisciplinary strategies for early adaptations to education and social life at school for young people with CFS/ME may benefit education and social development among peers for young people with CFS/ME. Lack of educational and social adaptations at school might lead to loss of education, social life and development among peers.

Bodies in lockdown: Young women’s narratives of falling severely ill with ME/CFS during childhood and adolescence

Abstract:

Thirteen women (16-30 years) storied their experiences about the process of falling severely ill with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome during childhood and adolescence. We performed a narrative analysis informed by phenomenology which yielded three central themes: The active and meaningful life I used to live; gradually developing unhomeliness and feeling pushed toward the edge; and left abandoned on the sidelines. Out of the incomprehensible and unpredictable emerges an understanding of the scale of their ordeal, along with advice that may have made it worse. This portrays a gradual developing uncertain, unhomely life situation with no outlooks for future recovery.
