The activation of complement and contact systems occurs in reperfusion injuries with initial tissue hypoxia, and lactic acidosis such as mycardial infarction and birth asphyxia. The aim of our experiment was the formal proof of activation by sole lactic acidosis. Lactic acid was added to blood and plasma samples from 10 healthy volunteers. C5a and factor XIIa were measured by EIA after incubati...

Biguanides are a drug of choice for the treatment of type 2 diabetes mellitus. Although they can cause lactic acidosis in susceptible patients with predisposing risk factors, the incidence of lactic acidosis is reported to be very low when they are used properly. We herein present a case of biguanide-associated severe lactic acidosis complicated with thiamine deficiency that was provoked withou...

Lactic acidosis is a clinical condition due to accumulation of H(+) ions from lactic acid, characterized by blood lactate levels >5 mM and arterial pH <7.25. In addition to supportive care, treatment usually consists of intravenous NaHCO(3), with a resultant mortality >60%. Dichloroacetate (DCA) is a compound that lowers blood lactate levels under various conditions in both man and laboratory a...

A 26 year old man with no previous history of convulsions presented in status epilepticus and severe lactic acidosis. He regained consciousness and the acidosis resolved after several hours of conservative management without intravenous bicarbonate, but he developed severe myalgia associated with marked elevation of creatine kinase and moderate raised plasma creatinine levels which resolved spo...

Albuterol is an uncommonly recognized culprit in causing lactic acidosis. While treating asthmatics, lactic acidosis creates a paradoxical situation in which, despite improvement in bronchospasm, patients look more dyspneic as a compensatory mechanism for metabolic acidosis. This might lead to misinterpretation of the situation with increased albuterol dosing, creating a sort of vicious cycle u...

OBJECTIVE To examine the evidence regarding the safety of metformin in heart failure. DATA SOURCES Searches in MEDLINE and International Pharmaceutical Abstracts were performed (1966-February 2007). Search terms included metformin, heart failure, lactic acidosis, clinical trials, and insulin resistance. STUDY SELECTION AND DATA EXTRACTION Published studies and case reports that evaluated th...

Lactic acidosis is a common cause of metabolic acidosis with high anion gap and is a potentially lethal complication of a number of diseases. It develops as a result of an imbalance between lactate production and utilization. Malignancies are a relatively uncommon cause between lactate production and utilization. Malignancies are a relatively uncommon cause. 18 An 84 year old woman was admitted...

Background: Metformin intoxication can potentially originate a lactic acidosis of variable severity, but possibly fatal, diagnosis and prompt treatment of which are crucial. The difficulty in establishing a clear cause and effect relationship arises from the multitude of biologic actions exerted by metformin. Objective: Review of literature in order to compile the current knowledge regarding th...

Metabolic acidosis frequently complicates sepsis and septic shock and may be deleterious to cellular function. Different types of metabolic acidosis (e.g., hyperchloremic and lactic acidosis) have been associated with different effects on the immune response, but direct comparative studies are lacking. Murine macrophage-like RAW 264.7 cells were cultured in complete medium with lactic acid or H...
