Abstract
Vasculitis is a rare complication of propylthiouracil therapy. Antineutrophil cytoplasmic antibodies (ANCA) have been described in association with several vasculitic disorders. We report detection of ANCA against human neutrophil elastase, proteinase 3, and myeloperoxidase in serum from six patients who developed evidence of vasculitis during propylthiouracil treatment of hyperthyroidism. On withdrawal of the drug ANCA concentrations fell and clinical symptoms resolved completely.
