BACKGROUND: ANCA is detected in several vasculitic diseases, including drug-induced systemic vasculitis: propylthiouracil (PTU), hydralazine, minocycline, penicillamine, allopurinol, procainamide, carbimazole, thiamazole, clozapine and phenytoin. All have been known to induce ANCA positive vasculitis in adult patients.
OBJECTIVE: To study the clinical manifestation, renal pathology and outcome of patients with ANCA positive vasculitis associated with propylthiouracil treatment in Siriraj Hospital.
MATERIAL AND METHOD: Retrospective study in 7patients with Graves' disease who were treated with propylthiouracil and developed ANCA-positive glomerulonephritis between 2000-2008.
RESULTS: Seven cases with Graves' disease who received propylthiouracil whose ages were 43 +/- 14 years. The duration of propylthiouracil treatment was 68.5 +/- 39 months and the doses were 50-150 mg per day. Six cases had P-ANCA and one case had C-ANCA in the serum. Proteinuria ranged from 0.49-2.9 gram per day. Mean serum creatinine was 2.05 mg/dl with creatinine clearance of 44 +/- 35 ml/min. The propylthiouracil was withdrawn in every patient and corticosteroid was administered. Renal remission was found until 1 year of follow-up.
CONCLUSION: ANCA positive glomerulonephritis associated with propylthiouracil is not uncommon. The average onset of glomerulonephritis is 2 years or more. The propylthiouracil dosage was not necessary high. Urinalysis and other glomerulonephritis symptoms should be screened for early diagnosis and appropriate treatment in patients treated with PTU.
