A 39-year-old Japanese woman had been receiving propylthiouracil for 5 years for hyperthyroidism when she developed myalgia, scleritis, proteinuria, fever, and inflammation of the nose. Examination of a renal biopsy specimen showed focal segmental necrotizing glomerulonephritis. Indirect immunofluorescent staining showed a highly positive perinuclear pattern of anti-neutrophil cytoplasmic antibody (ANCA) in her serum. Enzyme-linked immunosorbent assay (ELISA) of the ANCA showed positivity for anti-proteinase 3, anti-myeloperoxidase, anti-leukocyte elastase, and anti-lactoferrin, but anti-cathepsin G and anti-lysozyme were negative. Because ELISA showed the titer of anti-leukocyte elastase antibody to be markedly elevated, we challenged this data by performing dot blot analysis. The patient's serum reacted with the native form, but not with denatured leukocyte elastase. Propylthiouracil-induced vasculitis was suspected. Symptoms abated within 2 weeks and all values of ANCA were reduced after the drug was withdrawn. Vasculitis is a rare side-effect of propylthiouracil therapy. Recently it was reported in association with ANCA. We present the findings of this patient and compare them with those described in 19 published cases of propylthiouracil-induced vasculitis associated with ANCA.
