Connelly M, et al. - Using data from 7,753 persons recruited in the multinational Childhood Arthritis and Rheumatology Research Alliance Legacy Registry, experts ascertained the extent to which high levels of pain and functional limitations, and the strength of their relationship, are novel to youth with juvenile primary fibromyalgia syndrome/JPFS) with regard to other pediatric rheumatic diseases. Among conditions observed in pediatric rheumatology relative to ratings of pain and disability, JPFS was discovered to be unique. Nevertheless, in other pediatric rheumatic diseases, pain seems to be comparably or more greatly related to the level of functional impairment. Pain in childhood rheumatic disease, therefore, would profit from heightened prioritization for research and treatment.
