Metformin is a safe drug when correctly used in properly selected patients. In real life, however, associated lactic acidosis has been repeatedly, although rarely, reported. The term metformin-induced lactic acidosis refers to cases that cannot be explained by any major risk factor other than drug accumulation, usually due to renal failure. Treatment consists of vital function support and drug ...

A 33-year-old male was admitted to Michael Reese Hospital and Medical Center for evaluation of weight loss, dyspnea, and fever. He had factor Vill-deficient hemophilia and had been chronically ill over several months with a cough productive of scanty sputum, weight loss of 15 Ibs, low-grade fever, and progressive dyspnea on exertion. The medical history was notable for right total hip replaceme...

Most of the information about type B lactic acidosis associated with cancer is derived from case reports and there are no randomized controlled trials to compare different therapeutic modalities. Previous reviews of cases only refer to hematologic malignancies. We present a patient with non-Hodgkin's lymphoma who developed type B lactic acidosis. We performed a search of the PUBMED database usi...

Within solid tumor microenvironments, lactic acidosis, and hypoxia each have powerful effects on cancer pathophysiology. However, the influence that these processes exert on each other is unknown. Here, we report that a significant portion of the transcriptional response to hypoxia elicited in cancer cells is abolished by simultaneous exposure to lactic acidosis. In particular, lactic acidosis ...

OBJECTIVE Lactic acidosis has been associated with use of metformin. Hypoglycemia is a major concern using sulfonylureas. The aim of this study was to compare the risk of lactic acidosis and hypoglycemia among patients with type 2 diabetes using oral antidiabetes drugs. RESEARCH DESIGN AND METHODS This study is a nested case-control analysis using the U.K.-based General Practice Research Data...

Objective. To clarify the link between metformin accumulation and its metabolic consequences by taking the time frame for metformin measurement into account. Research Design and Methods. Our database was studied for cases of metformin accumulation and lactic acidosis status available on admission, and then we selected patients in whom arterial pH, blood lactate, and plasma and erythrocyte metfo...

were first used clinically for diabetes mellitus in the 1950s. Since phenformin was found to have a lethal side effect, lactic acidosis, in the late of 1970s, its usage decreased rapidly in many countries and was finally withdrawn. Then use of other biguanides declined gradually because of their own adverse effects. Lactic acidosis, hypoglycemia, and digestive organ dysfunction have been found ...

BACKGROUND Lactic acidosis is a common cause of high anion gap metabolic acidosis. Sodium bicarbonate may be considered for an arterial pH <7.15 but paradoxically depresses cardiac performance and exacerbates acidosis by enhancing lactate production. This study aimed to evaluate the cause and mortality rate of lactic acidosis and to investigate the effect of factors, including sodium bicarbonat...

Ten patients with severe megaloblastic anaemia were studied to investigate whether the causative metabolic defects might predispose them to lactic or other acidosis. One patient had compensated acidosis with hyperlactataemia before treatment but there were obvious causes other than anaemia. No other patient developed an acidosis. Neither anaemia per se nor the metabolic defects of vitamin B(12)...
