ANTINEUTROPHIL CYTOPLASMIC ANTIBODY-POSITIVE CRESCENTIC GLOMERULONEPHRITIS ASSOCIATED WITH ANTI-THYROID DRUG TREATMENT

Abstract

Two cases of antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis following treatment with propylthiouracil and carbimazole are described. Both patients had crescentic glomerulonephritis proven by renal biopsy and responded to immunosuppressive therapy and withdrawal of the anti-thyroid drugs. Though systemic vasculitis associated with propylthiouracil is reported, this is the first report to our knowledge of renal biopsy-proven vasculitis associated with either of these drugs.
