Chronic fetal hyperinsulinemia, similar to that found in human infants of diabetic mothers, was produced in fetal rhesus monkeys during the latter third of gestation. Fetal plasma glucose and amino acid concentrations were found to be inversely logarithmically correlated with plasma insulin concentration. Fetal plasma glucagon concentrations were suppressed by hyperinsulinemia. Fetal plasma erythropoietin concentrations were increased by hyperinsulinemia in a dose/response manner. The activity of the hepatic gluconeogenic enzymes glucose-6-phosphatase and total phosphoenolpyruvate carboxykinase were reduced by hyperinsulinemia. Fatty acid synthase complex activity was, in contrast, increased by hyperinsulinemia while citrate cleavage enzyme and glucose-6-phosphate dehydrogenase were only increased when supraphysiologic hyperinsulinemia was produced. This model provides an opportunity to study the metabolic effects of hyperinsulinemia separate from those of hyperglycemia on the primate fetus, making it a useful model for the study of fetal pathologic conditions in diabetic pregnancies.
