Km. Dolman et al., VASCULITIS AND ANTINEUTROPHIL CYTOPLASMIC AUTOANTIBODIES ASSOCIATED WITH PROPYLTHIOURACIL THERAPY, Lancet, 342(8872), 1993, pp. 651-652
Vasculitis is a rare complication of propylthiouracil therapy. Antineu
trophil cytoplasmic antibodies (ANCA) have been described in associati
on with several vasculitic disorders. We report detection of ANCA agai
nst human neutrophil elastase, proteinase 3, and myeloperoxidase in se
rum from six patients who developed evidence of vasculitis during prop
ylthiouracil treatment of hyperthyroidism. On withdrawal of the drug A
NCA concentrations fell and clinical symptoms resolved completely.
