title: [Neonatal lactic acidosis caused by severe pyruvate carboxylase deficiency].
abstract: A new patient with neonatal lactic acidosis due to pyruvate carboxylase deficiency is described. Since birth he developed vomiting, hypothermia, lethargy, irritability, hypoglycemia and severe metabolic acidosis. During admission a progressive deterioration was observed. Despite different attempted therapies patient died at 4 1/2 months of age. High levels of plasma and urine lactate and pyruvate were detected. Enzymatic studies in cultures skin fibroblasts and postmortem tissues showed a severe deficiency of pyruvate carboxylase.
