We report a preterm infant who was prescribed an MCT formula and subsequently developed carnitine deficiency with liver dysfunction and an elevation of serum CK level. A male infant who had been born at 24 weeks' gestation with birth weight 799 g, was fed with an MCT formula containing 76.8% of all kinds of lipids, because of his steatorrhea after the 30th day. On the 100th day, he was noted hepatomegaly and elevation of serum levels of AST, ALT and CK. The needle biopsy of the liver indicated the existence of the liver damage. He showed low serum carnitine with high urinary loss of acylcarnitine and dicarboxylic aciduria. Administration of L-carnitine was an effective treatment. The carnitine deficiency might be exaggerated by an increased urinary loss of acylcarnitine. We should be cautious of the risk of carnitine deficiency in preterm infants during prolonged use of MCT formula.

A rare case of glycogen storage disease type III with unusually absent ketone body production during hypoglycemia is presented. A 10-month-old boy presented with asymptomatic hepatomegaly. GOT/GPT 2555/1160 IU/L, CK 302 IU/L, triglycerides 1223 mg/dL, cholesterol 702 mg/dL and uric acid 7.9 mg/dL. After a 9-hour fast, glucose was 27 mg/dL and adequate lipolysis without ketogenesis was observed (total/free carnitine 34.5/20 micromol/L, free fatty acids 1620 micromol/L and beta-hydroxybutyrate 172 micromol/L). Result of MCT (medium-chain triglycerides) load test: basal hydroxybutyrate 29 micromol/L rose to 5748 micromol/L. Treatment with a fat-restricted diet supplemented with formula containing MCT was initiated and the patient presented a satisfactory initial evolution. Three months later, CK were 3000 IU/L. Muscle biopsy was diagnostic of glycogenosis. Enzymatic activity in skin fibroblasts was 0% for amylo-1,6-glucosidase. The diagnosis of glycogenosis type III was established. Echocardiography performed at that time showed non-obstructive ventricular hypertrophy. Until now hypoketosis during hypoglycemia has only been described in glycogenosis type I.
