[Recurrent acidosis with hypoglycemia in an infant: fructose-1,6-diphosphatase deficiency].
A seven months old infant presented with recurrent episodes of acidosis and hypoglycemia triggered by fasting and febrile infections. The diagnosis of fructose-1,6-diphosphatase deficiency was made by demonstrating the enzyme deficiency in a liver biopsy specimen. Fructose-1,6-diphosphatase is a key enzyme of gluconeogenesis. Fructose-1,6-diphosphatase deficiency results in hypoglycemia and lactic acidosis during episodes of fasting. Diagnosis is made preferably by liver biopsy. Treatment includes elimination of fructose and sucrose from the diet and avoidance of fasting. Acute attacks are treated by intravenous infusion of glucose and bicarbonate if necessary.
