Acute Renal Failure, Lactic Acidosis, and Metformin: Two Case Reports and Literature Review
Abstract
Lactic acidosis is a potential adverse event related to metformin therapy. Although metformin-associated lactic acidosis (MALA) is a rare condition (about 10 cases / 100,000 patients / year), new cases continue to be reported, with a mortality of 40-50%. We describe two clinical cases characterized by severe metabolic acidosis, hyperlactacidemia, and acute renal injury. The first also with NSTEMI, successfully treated.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 100,000 participants or records.
