ABSTRACT To assess the relation between fatigue and somatic symptoms in healthy adolescents and adolescents with chronic fatigue syndrome/myalgic encephalopathy (CFS/ME).
Seventy two adolescents with CFS were compared within a cross-sectional study design with 167 healthy controls. Fatigue and somatic complaints were measured using self-report questionnaires, respectively the subscale subjective fatigue of the Checklist Individual Strength (CIS-20) and the Children's Somatization Inventory.
Healthy adolescents reported the same somatic symptoms as adolescents with CFS/ME, but with a lower score of severity. The top 10 somatic complaints were the same: low energy, headache, heaviness in arms/legs, dizziness, sore muscles, hot/cold spells, weakness in body parts, pain in joints, nausea/upset stomach, back pain. There was a clear positive relation between log somatic symptoms and fatigue (linear regression coefficient: 0.041 points log somatic complaints per score point fatigue, 95% CI 0.033 to 0.049) which did not depend on disease status.
Results suggest a continuum with a gradual transition from fatigue with associated symptoms in healthy adolescents to the symptom complex of CFS/ME.

    ABSTRACT: Chronic Fatigue Syndrome or Myalgic Encephalomyelitis (CFS/ME) in children is characterized by persistent or recurrent debilitating fatigue which results in a substantial reduction in activity. There is a growing interest in the use of questionnaires, or patient-reported outcome measures (PROMs), to assess how patients function and feel in relation to their health and associated healthcare. However, guidance for PROM selection for children with CFS/ME does not exist. We reviewed the quality and acceptability of PROMs used with children with CFS/ME to inform recommendations for practice. We conducted a systematic review of PROMs completed by children with CFS/ME. The quality of the evaluative studies and the reviewed measures were assessed against recommended criteria using an appraisal framework and the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. We sought evidence of measurement (reliability, validity, responsiveness, interpretability, data quality) and practical properties (acceptability, relevance, feasibility). Sixteen articles were included in the review, providing evidence of reliability and/or validity for 13 PROMs. Of these, five were child-specific (one health-related quality-of-life; four emotional well-being) and eight were not (four emotional well-being, three fatigue-specific; and one generic). All measures had limited evidence of measurement properties and no evidence of practical properties. Recommendations for patient-reported assessment are difficult to make because of limited evidence of the quality and acceptability of PROMs for children with CFS/ME. The appraisal method highlighted significant methodological and quality issues which must be addressed in future research. There is a lack of qualitative evidence describing the outcomes of healthcare that are important to children with CFS/ME, and the relevance or appropriateness of available measures. Future PROM development and evaluation in this group must seek to involve children collaboratively to ensure that the outcomes that children care about are assessed in an acceptable way.

    ABSTRACT: Fatigue is an important symptom in adult multiple sclerosis (MS) and it is likely to occur in children with MS. It is currently unknown whether children who experienced a monophasic inflammatory demyelinating event of the central nervous system in the past also suffer from fatigue. We studied the presence and severity of fatigue in 32 children (18 boys, 14 girls) between 11-17 years old (mean: 14 years, 10 months) with a monophasic inflammatory demyelinating disease (n=22) or definite MS (n=10). This was measured with the Checklist Individual Strength. A score of >or=40 on the severity of fatigue subscale indicated the presence of severe fatigue. We also examined the relation between fatigue and depression (assessed by the Child Depression Inventory). Additionally we measured the health-related quality of life (HRQoL), using the TNO-AZL Child Quality of Life child form. We compared the scores of the MS and monophasic patients with the scores of healthy Dutch children. The highest scores on the fatigue scales subjective fatigue and physical activity were found in the children with MS. Only 1 of the monophasic patients suffered from severe fatigue in contrast to 4 of the MS patients. In the MS group fatigue and depression were correlated. MS patients experienced a lower HRQoL on the scales locomotor functioning, cognitive functioning and interaction with peers. The occurrence of fatigue is very rare after a monophasic inflammatory demyelinating event in the past. As expected, fatigue occurs more frequent in paediatric MS patients.

    ABSTRACT: Objectives: Although pain is a significant symptom in chronic fatigue syndrome (CFS), pain is poorly understood in adolescents with CFS. The aim of this study was to explore pain distribution and prevalence, pain intensity and its functional interference in everyday life, as well as pressure pain thresholds (PPT) in adolescents with CFS and compare this with a control group of healthy adolescents (HC). Methods: This is a case-control, cross-sectional study on pain including 120 adolescents with CFS and 39 HCs, aged 12-18 years. We measured pain frequency, pain severity and pain interference using self-reporting questionnaires. PPT was measured using pressure algometry. Data were collected from March 2010 until October 2012 as part of the Norwegian Study of Chronic Fatigue Syndrome in Adolescents: Pathophysiology and Intervention Trial. Results: Adolescents with CFS had significantly lower PPTs compared with HCs (p<0.001). The Pain Severity Score and the Pain Interference Score were significantly higher in adolescents with CFS compared with HCs (p<0.001). Almost all adolescents with CFS experienced headache, abdominal pain and/or pain in muscles and joints. Moreover, in all sites, the pain intensity levels were significantly higher than in HCs (p<0.001). Conclusions: We found a higher prevalence of severe pain among adolescents with CFS and lowered pain thresholds compared with HCs. The mechanisms, however, are still obscure. Large longitudinal population surveys are warranted measuring pain thresholds prior to the onset of CFS.
