DEHESA-LOPEZ, E et al. A rare case of persistent lactic acidosis. Med. interna Méx. [online]. 2017, vol.33, n.3, pp.415-420. ISSN 0186-4866.

This paper reports the case of a 72-year-old female patient with type 2 diabetes mellitus treated with metformin. She was admitted for abdominal pain, diarrhea, fever and somnolence. The initial diagnoses were severe sepsis, acute kidney injury with dialysis criteria and severe lactic acidosis secondary to septic shock and metformin. The medical treatment was with crystalloid solutions, intravenous antibiotics, intravenous bicarbonate infusion, vasopressors, mechanical ventilation and hemodialysis. The clinical course was initially satisfactory; however, the patient persisted with severe hyperlactatemia despite 3 hemodialysis sessions, mean arterial pressure above 65 mmHg with minimum dose of vasopressor and normal liver function tests. In the control abdominal CT, multiple and extensive hepatic infarcts were documented secondary to hepatic artery thrombosis, not observed in the abdominal CT performed at hospital admission.
