title: Effects of branched chain amino acid infusion on glucose metabolism in cirrhotic patients with encephalopathy.
abstract: An amino acid solution enriched in branched chain amino acids (BCAA) was administered to cirrhotic patients with encephalopathy and serial determinations of serum glucose, IRI and IRG were performed. Slight decrease of serum glucose was observed when only BCAA was given. On the other hand, when BCAA was infused with glucose, the serum glucose level decreased significantly after infusion (-77.5 +/- 26.2 mg/dl, p less than 0.01) and two cases of hypoglycemic shock were observed. Although both serum insulin and glucagon increased in these cases, the IRI/IRG molar ratio which was 8.9 at the start of infusion increased to 20.6 at the end of infusion. It was suggested that administration of BCAA with glucose caused hypoglycemia in cirrhotics with encephalopathy, possibly by synergistic action of BCAA and glucose on serum insulin level.
