Abstract:
Objective: To examine demographic and clinical characteristics of individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) with and without joint hypermobility We hypothesized that JH+ patients would have an earlier onset of ME/CFS symptoms as well as increased severity, greater number of co-morbid conditions, and lower health related quality of life.
Study design: From an observational cohort study of 55 individuals meeting the Fukuda criteria for ME/CFS, we compared groups using a Beighton score cut-off of 4 or higher to indicate JH. Chart data were collected to examine the age and type of onset of ME/CFS, and the presence of comorbid conditions. The impact on quality of life was assessed through questionnaires that included the Peds QL, Functional Disability Inventory, Peds QL Multidimensional Fatigue Scale, and Anxiety Subscale of the Symptom Checklist 90.
Results: There was no significant difference between groups in mean (SD) age at onset of ME/CFS (13.3 [3.3] years vs 13.3 [2.3] years; P = .92), sex, frequency, and severity of ME/CFS symptoms, orthostatic intolerance symptoms, or comorbid conditions. There was no significant difference between groups in measures of health-related quality of life using a Beighton score cut-off of 4 or a cut-off of 5 to define joint hypermobility.
Conclusions: Despite being a risk factor for the development of ME/CFS, JH as defined in this study was not associated with other clinical characteristics of the illness.
