title: Diabetes and hypoglycemia due to insulin antibodies.
abstract: A patient with "autoimmune diabetes" with reactive hypoglycemia due to anti-insulin antibodies is described. The pathophysiology of the impaired carbohydrate tolerance and reactive hypoglycemia is illustrated by measurements of C-peptide, and free and antibody-bound insulin. Detailed analysis of her antibodies did not provide any evidence in favor of exogenous insulin immunization. Nevertheless, a possible cause of unsuspected insulin immunization was present in her history which should be considered in other reported cases of "autoimmune diabetes" due to insulin antibodies in which exposure to insulin cannot be documented.
