Elevated lactate and pyruvate
WebMay 4, 1976 · This infant was found to have lactic acidosis, low cerebrospinal fluid glucose, hyperalaninemia, and increased levels of urine lactate, pyruvate and alanine. These laboratory studies suggested an inborn error in gluconeogenesis. Further investigation revealed a low level of hepatic pyruvate carboxylase activity.

WebMar 4, 2024 · Lactate is produced via pyruvate metabolism under anaerobic or aerobic glycolytic conditions. In the presence of adequate oxygen and mitochondrial capacity, pyruvate is normally converted to acetyl CoA which then enters the Krebs cycle. In the absence of oxygen or in the presence of excessive glycolysis, pyruvate is shunted into … WebIntrarenal hypoxia develops within a few days after the onset of insulinopenic diabetes in an experimental animal model (ie, a model of type-1 diabetes). Although diabetes-induced hypoxia results in increased renal lactate formation, mitochondrial function is well maintained, a condition commonly referred to as pseudohypoxia. However, the metabolic …
