Abstract After transfer of diabetic patients from porcine to human insulin, many reports emerged supporting an increased hypoglycemia unawareness. Several studies were then undertaken in both diabetic and healthy adults to investigate counterregulatory hormone responses to both porcine and human insulin-induced hypoglycemia as a possible underlying cause for this different hypoglycemia awareness. Most studies demonstrated similar neuroendocrine responses to both insulin species in adults. However, no such studies have ever been performed in healthy children. We undertook a double-blinded study of counterregulatory hormone responses to both porcine and human insulin-induced hypoglycemia in 17 short normal children randomly assigned to two groups, one receiving human and the other porcine insulin. We found similar responses of growth hormone, cortisol, epinephrine, norepinephrine and dopamine to both porcine insulin- and human insulin- induced hypoglycemia. Interestingly, we observed a significantly higher glucagon secretion when hypoglycemia was induced by human insulin. In conclusion, human insulin induces a higher glucagon secretion in healthy children than porcine insulin. Evidently, this observation cannot be extrapolated to diabetic patients. This study, however, further underlines the importance of performing investigations in children, since results found in adults differ from those observed in children.
