Objective. To develop and validate a self-or parent-administered instrument for measuring functional status in children with juvenile rheumatoid arthritis (JRA).Methods. We adapted the Stanford Health Assessment Questionnaire (HAQ) for use in children ages 1-19 years, by adding several new questions, such that for each functional area, there was at least 1 question relevant to children of all ages. The face validity of the instrument was evaluated by a group of 20 health professionals and parents of 22 healthy children. reliability, studied at a 2-week interval, revealed virtually identical Disability Index scores measured on the 2 occasions (0.96 versus 0.96; P > 0.9 by paired t-test; Spearman's correlation coefficient = 0.8, P < 0.002).Conclusion. The Childhood HAQ, which takes less than 10 minutes to complete, is a valid, reliable, and sensitive instrument for measuring functional status in children with JRA.
Objective. Neonatal-onset multisystem inflammatory disease (NOMID; also known as chronic infantile neurologic, cutaneous, articular [CINCA] syndrome) is characterized by fever, chronic meningitis, uveitis, sensorineural hearing loss, urticarial skin rash, and a characteristic deforming arthropathy. We investigated whether patients with this disorder have mutations in CIAS1, the gene which causes Muckle-Wells syndrome and familial cold autoinflammatory syndrome, two dominantly inherited disorders with some similarities to NOMID/CINCA syndrome.Methods. Genomic DNA from 13 patients with classic manifestations of NOMID/CINCA syndrome and their available parents was screened for CIAS1 mutations by automated DNA sequencing. Cytokine messenger RNA (mRNA) levels were assessed by real-time polymerase chain reaction on peripheral blood leukocyte mRNA, and serum cytokine levels were assayed by enzyme-linked immunosorbent assay. Protein expression was assessed by Western blotting of lysates from plastic-adherent peripheral blood mononuclear cells.Results. In 6 of the 13 patients, we found 6 heterozygous missense substitutions in CIAS1. Five of the 6 mutations are novel. None of these sequence changes was observed in a panel of >900 chromosomes from healthy controls. Two distinct nucleotide changes in a single codon in unrelated patients resulted in the same amino acid change. In 4 mutation-positive children whose parental DNA was available, no mutation was found in the parental DNA, supporting the conclusion that the mutations arose de novo. Consistent with
MMF appears to be effective in arresting disease progression in severe or MTX-refractory JLS and is generally well tolerated. Further controlled studies are needed to confirm these data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
