title: Transient diabetes mellitus in a neonate. Evaluation of insulin, glucagon, and growth hormone secretion and management with a continuous low-dose insulin infusion.
abstract: This neonate developed marked hyperglycemia four days after birth and required insulin therapy for eight weeks. During the acute phase of the disease, immunoreactive insulin was undetectable in portal venous serum. Neither tolbutamide nor theophylline administration significantly triggered insulin secretion. Somatostatin infusion inhibited growth hormone release but had no effect on plasma glucagon or blood glucose concentrations. At 2 1/2 months, two weeks after insulin withdrawal, the infant was still intolerant to an oral glucose load, insulin response was markedly delayed, and growth hormone secretion was paradoxical. At five months, the insulin, glucagon, and growth hormone responses to glucose and to somatostatin were normalized. Thus, in this patient, insulin secretion was transiently deficient. Peculiarities of glucagon and growth hormone secretion were also present but are more characteristic of this age group than of diabetes. The hyperglycemic state was managed by intraportal infusion of 0.1 to 0.2 IU regular insulin/kg/hour. This mode of insulin administration proved efficient, secure, and easy to manage.
