Goodpasture's syndrome in a patient receiving penicillamine and carbimazole.

A 51-year-old woman with advanced rheumatoid arthritis developed a Goodpasture's syndrome during treatment with penicillamine and carbimazole. Circulating antiglomerular basement membrane antibodies (anti-GBM) were present. Renal biopsy showed focal necrotizing glomerulonephritis with crescents, and HLA typing showed the presence of DR3 and DR4. The patient responded dramatically to pulse methylprednisolone and cyclophosphamide, with both clinical remission and disappearance of anti-GBM antibodies.
