3 Workup of the Patient with Lactic Acidemia – Mitochondrial Disease Glycogen OPO3H2 CH2 = CCOOH William L. Nyhan NH2 O CH3 C -COOH CH3 CHCOOH Key Facts › › › › › Inborn errors characterized by lactic acidemia fall into two categories: abnormalities in gluconeogenesis and defects of oxidation. Distinction is important because management and prognosis are different. As a first step exclude factitious and secondary elevations of levels of lactic acid in order to focus on specifics of work-up. Ratios of lactate to pyruvate and 3-hydroxybutyrate to acetoacetate are useful in elucidating the area of metabolic defect.

If the patient is asymptomatic, glucagon is given again. During this time if there is no rise in glucose, the defect is in gluconeogenesis. Glucose is given intravenously to restore normoglycemia without waiting for the usual interval of a glucagon test, and in the presence of any symptoms is given immediately without testing glucagon responsiveness. Concentrations of lactic and pyruvic acids, alanine, acylcarnitines, free fatty acids, and ketone bodies are determined at the end of the fast. In a hypoglycemic patient concentrations of insulin, growth hormone and glucagon are also obtained at the time the fast is terminated.

We have diagnosed NARP mutation in a patient who carried a radiological diagnosis of acute demyelinating encephalomyelitis. Basal ganglia lesions are also characteristic of propionic acidemia and methylmalonic acidemia. 2 Work-up of the Patient with Metabolic Acidosis and Massive Ketosis William L. Nyhan Key Facts › › › › › Massive ketosis in a neonate or young infant is a key to the diagnosis of an organic aciduria. Testing of the urine for ketones is a must in all ill infants. The most frequent organic acidurias are propionic aciduria, methylmalonic aciduria, multiple carboxylase deficiency, isovaleric aciduria, and 3-oxothiolase deficiency.
