title: Interleukin-2 production by lymphocytes from blood of children with arthritis is less suppressed than in systemic lupus or cystic fibrosis.
abstract: Interleukin-2 (IL-2) production by cells from children with various forms of arthritis, systemic lupus erythematosus, and cystic fibrosis was compared. In all cases more IL-2 was detectable at 24 than at 48 h and production was increased by addition of indomethacin. Cultures from children with either active lupus or the pneumonia of cystic fibrosis produced very little IL-2, but cultures from children with arthritis produced apparently normal amounts. We conclude that depressed production of IL-2 in juvenile arthritis may be a secondary epiphenomenon and not a primary immunologic deficit.
