Abstract

We present the case of a 42-year-old female patient who attempted suicide by taking approximately 100 tablets of metformin (500 mg). Laboratory tests revealed severe lactic acidosis with lactate levels of 24 mmol/L and pH of 7.09. The patient was treated with high-volume continuous venovenous hemodiafiltration (CVVH) and resin-sorbent hemoperfusion. Metformin concentrations were measured by high-performance liquid chromatography during CVVH and hemoperfusion treatment. Before extracorporeal treatment, the plasma metformin concentration was 208.5 mg/L. After CVVH treatment for 24 h, the plasma metformin concentration had decreased to 13.9 mg/L. Resin-based sorbent hemoperfusion plus CVVH treatment had reduced the metformin plasma concentration by 61.8% after 3 h. After 7 days, the patient's laboratory tests and clinical syndrome were improved, and she was discharged from hospital. We provide evidence that CVVH plus hemoperfusion is effective in eliminating metformins and metabolic products.
