title: Rapidly progressive glomerulonephritis in a patient with rheumatoid arthritis during treatment with high-dosage D-penicillamine.
abstract: A patient with advanced rheumatoid arthritis and severe clinical manifestations of rheumatoid vasculitis died of acute renal failure after 30 months of treatment with high-dosage D-penicillamine. She had had no signs of adverse drug reactions until the terminal illness. Although streptococcal pharyngitis was diagnosed late in her disease, penicillamine-induced immune complex glomerular damage is considered more likely than poststreptococcal glomerulonephritis, because her microscopic hematuria preceded diagnosis of pharyngitis. Postmortem examination disclosed findings suggestive of rapidly progressive glomerulonephritis of immune complex pathogenesis. The short period of microscopic hematuria and the rapidity of development of renal failure before death emphasize the need for frequent monitoring of renal function and prompt discontinuation of D-penicillamine treatment upon detection of otherwise unexplained hematuria. There is urgent need for early immunological evaluation, renal biopsy, and vigorous therapeutic measures.
