Summary A 79-year-old Japanese male with a history of type 2 diabetes mellitus (T2DM) for 16 years was admitted to evaluate possible renal disease. The T2DM was well controlled in this patient using nutrition therapy without the need for any diabetes medication, and both diabetes retinopathy and proteinuria were negative. At the age of 78 advanced colorectal cancer (stage IIIa) was diagnosed and laparoscopic-assisted colectomy was performed. Following this procedure, the patient began treatment with tegafur/gimeracil/oteracil (S-1), 80 mg twice daily for 28 days of 42-day cycle. The patient received S-1 for 6 months, during which time, serum albumin decreased from 3.0 g/dL to 1.1 g/dL, urinary protein increased from negative to 3.0 g/day, and serum creatinine increased from 0.9 mg/dL to 2.1 mg/dL. Treatment with S-1 was discontinued, and furosemide 180 mg and prednisolone 30 mg treatment was initiated; however, serum creatinine levels continued to increase to 7.2 mg/dL and proteinuria continued to increase reaching a nephrotic range. A disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) activity was decreased to 27.0%. Renal biopsy showed Kimmelstiel-Wilson nodules, while immunofluorescence intensity of IgG subclass was IgG1 dominant, which was not compatible with diabetic nephropathy (DN). Plasma exchange was not affected. However, hemodialysis was initiated.The results of this investigation suggest that when S-1 monotherapy is performed in the case with DN, rapidly progressive glomerulonephritis (RPGN) may develop due to a condition similar to thrombotic microangiopathy, even in patients with a minor risk factor of DN.
