A 26-year-old male with nephrotic syndrome (NS) due to alpha-mercaptopropionyl glycine (MPG) is described. In March, 1988, he was diagnosed as having familial cystinuria after receiving urolithiasis treatment since December, 1985. Massive proteinuria and slight pedal edema were noted. Nephrotic syndrome was suggested and renal biopsy was performed. The renal pathological finding demonstrated membranous glomerulonephritis (MN) at stage I. This case was defined as NS clinically associated with MPG, and glucocorticoid intake was initiated. The response to the glucocorticoids was fairly good with no clinical problems after discontinuation of MPG, and the cystinuria was maintained with alkaline medication. The patient's parents and younger brother were suggested and confirmed to have cystinuria based on urinary aminogram analysis, but displayed no symptoms. We present a rare case of NS due to MPG therapy in a patient with familial cystinuria. However, the mechanism of onset remains unclear.

A 65-year-old man was admitted to our hospital because of thirstyness and left lower abdominal pain. On admission, he was found to have urolithiasis, renal insufficiency (BUN: 73 mg/dl, Crt: 4.4 mg/dl), and hypercalcemia (13.2 mg/dl). Chest X-ray films and computed tomograms showed enlargement and calcification of the hilar lymph nodes, and thickened interlobar fissures in both lungs. Levels of angiotensin converting enzyme (30.2 IU/l) and 1.25 (OH)2VitD3 (66.4 pg/ml) were elevated. Histologic examination of the specimen obtained from transbronchial lung biopsy showed non-caseous epithelioid cell granulomas. Because the level of parathyroid hormone was normal and no malignancies were detected, a diagnosis of sarcoidosis was made. Treatment with extracorporeal shock wave lithotripsy, transurethral lithotomy, saline infusion, and prednisolone (30 mg/day) alleviated the urolithiasis, renal insufficiency, and hypercalcemia. After discharge, the patient was followed up and given prednisolone therapy. About 1 month after the prednisolone dose had been tapered to 15 mg/day, the patient experienced dyspnea and facial and pedal edema. Because congestive heart failure was diagnosed, he was re-admitted to our hospital for a second time. Although he was then placed on intensive therapy, he died of ventricular tachycardia associated with sarcoidosis of the heart.
