Thionamide drugs are widely used in the management of hyperthyroidism and are infrequently associated with adverse reactions. We report the development of the nephrotic syndrome during methimazole (Tapazole) therapy in a young man with Graves' disease. His proteinuria remitted promptly with discontinuance of the drug, and renal histologic features bore a striking resemblance to the toxic nephrosis induced in animals by the aminonucleoside of puromycin. In view of the histologic similarities, we propose that methimazole acted as a direct glomerular toxin, inducing the nephrotic syndrome in this patient.

A 15-year-old girl had a history of diffuse goiter and received methimazole treatment 2 months before admission to the hospital. She developed bilateral lower leg edema 5 days before admission and the laboratory examinations revealed leukopenia, anemia, proteinuria, and granular cast. Positive antinuclear antibodies and anti-double strand (anti-ds) DNA antibodies were noted, although complement levels were not reduced. Myeloperoxidase antineutrophil cytoplasmic antibody was positive. A renal biopsy disclosed that there was focal segmental glomerulosclerosis. Methimazole was discontinued, and she was treated with prednisolone and Plaquenil, after which the symptoms and laboratory tests became normal within 40 days. The prednisolone was discontinued after treatment for seven months. Currently, the anti-dsDNA, C3, C4, CBC, urinalysis, and thyroid function tests are within normal limits. With hydroxychloroquine and levothyroxine, she was free of symptoms after discontinuation of methimazole until now (about 21 months).

A 72-year-old woman was admitted to our hospital because of massive proteinuria of 2.2 g/day. She had seen a general practitioner for management of Basedow disease, diabetes mellitus and hypertension for 24 years. On admission, she complained of anorexia and nausea. Laboratory data showed serum creatinine of 3.62 mg/dL and MPO-ANCA of 68 EU. Renal biopsy revealed crescentic glomerulonephritis complicated with membranous nephropathy. Thiamazole (MMI), which was being given for Basedow disease for years, was withdrawn on the suspicion as a cause of MPO-ANCA. Three years after the withdrawal of MMI, renal failure slowly progressed to the end-stage, while MPO-ANCA was negative. She was introduced onto hemodialysis. At that time, MPO-ANCA became positive again, the titer being 12.9 EU. Therefore, we suspected a relapse of ANCA-related vasculitis and performed steroid pulse therapy on the patient with methylprednisolone at 0.5 g/day for 3 days. On hospital day 14, MPO-ANCA became negative. On day 25, however, severe acute pancreatitis developed and a pancreatic tumor lesion was found on CT. In spite of amelioration of the pancreatitis by medical treatment, the pancreatic tumor lesion did not show any significant change. On day 48, she died of multiple organ failure. Autopsy showed a mucinous cyst adenoma of pancreas and necrotizing pancreatitis. We suspected steroid therapy as the cause of the pancreatic lesions.
