Abstract

CASE: A 64-year-old Japanese woman with diabetes mellitus was admitted for hypoglycemia. Her diabetes had been under good control with glimepiride, voglibose, exenatide, and metformin for a few years. Although overt proteinuria was observed, the serum creatinine values were within normal range during the routine outpatient follow-up. Hypoglycemic attack caused by glimepiride and loss of appetite by urinary tract infection were diagnosed. Then, metformin-associated lactic acidosis with acute renal failure caused by dehydration was detected.

OUTCOME: Her condition was improved by continuous veno-venous hemodiafiltration and hemodialysis, known to be useful to remove metformin.

CONCLUSION: We reported a case of metformin-associated lactic acidosis with hypoglycemia during routine treatment of diabetes that was successfully rescued by early renal replacement therapy.
