Clinical Characteristics of Myeloperoxidase Antineutrophil Cytoplasmic Antibody-Associated Vasculitis Caused by Antithyroid Drugs

Abstract

The time of onset of MPO-ANCA-associated vasculitis and the dose at onset varied. The severity and number of organs involved were not correlated with the MPO-ANCA titer, indicating a need for vigilance even when the MPO-ANCA titer is only weakly positive.
