title: Impaired glucocorticoid induction of mononuclear leukocyte lipocortin-1 in rheumatoid arthritis.
abstract: OBJECTIVE
  To investigate leukocyte lipocortin-1 production in rheumatoid arthritis (RA).
  
  
  METHODS
  Eight control and 8 RA subjects received 100 mg hydrocortisone intravenously. Leukocyte lipocortin-1 was measured by enzyme-linked immunosorbent assay.
  
  
  RESULTS
  Hydrocortisone induced significant increases in lipocortin-1 production by control mononuclear cells (MNC) (P = 0.006 versus baseline) but not by RA MNC (P = 0.44 versus baseline). Peak lipocortin-1 levels in control MNC were significantly higher than those in RA MNC (P = 0.014).
  
  
  CONCLUSIONS
  These results indicate that glucocorticoid-induced MNC lipocortin-1 production is impaired in RA.
