title: Neonatal diabetes with hyperchylomicronemia.
abstract: Neonatal diabetes mellitus (NDM) is defined as hyperglycemia occurring in the first few weeks of life. It can be either transient (TNDM) or permanent (PNDM). A 25 days old newborn was brought to the hospital with restlessness, respiratory depression and cyanosis. He was born at term with a birth weight of 2,000 g. There was no consanguinity between his parents. His physical examination findings were as follows: Weight and height were under 3th percentile, he was hypoactive and dehydrated. Serum glucose level was 800 mg/dl; C-peptide was 0.41 ng/ml. Upon investigation for dyslipidemia in association with his neonatal diabetes, hyperchylomicronemia was found both in the patient and his father. Pancreatitis, anemia and cholestasis were also observed. Insulin treatment was started for his diabetes together with a special diet for dyslipidemia. At the end of 28 months of follow-up, dyslipidemia has resolved but the need for insulin therapy was still existing. However, TNDM was considered in differential diagnosis because he was small for gestational age (SGA) at birth and his symptoms had started at the 25th day of the neonatal period. Delayed recovery from insulin dependency brought out the possibility of PNDM. Furthermore, neonatal diabetes combined with hypechylomicronemia is a rare clinical picture. Reported cases of NDM with different clinical evaluation will help to better understanding of this disorder.
