However, insulin autoantibodies in nondiabetic subjects can occasionally develop without exposure to exogenous insulin and may rarely become a cause of episodic hypoglycemia. In this setting their presence can be an indicator of "factitious hypoglycemia" due to the surreptitious injection of insulin, rather than to a clinical problem (eg, insulinoma). Insulin antibodies may be found in nondiabetic individuals complaining of hypoglycemic attacks. Larger therapeutic doses may be required because of antibody-induced insulin resistance. Insulin autoantibody production is more common when therapeutic insulin of animal origin is used (rarely used in contemporary practice). However, after insulin therapy is initiated, autoantibody production may recur as a memory response. ![]() Once type 1 diabetes has fully manifested, insulin autoantibody levels usually fall to low or undetectable levels. ![]() In genetically predisposed, but disease-free, individuals (first degree relatives of patients with type 1 diabetes or individuals with permissive human leukocyte antigen alleles), detection of multiple islet cell autoantibodies is a strong predictor for subsequent development of type I diabetes. The level of these autoantibodies is generally low and may even fall during follow-up. The onset of autoimmune diabetes mellitus (type 1 diabetes mellitus) is preceded (and accompanied) by the appearance of autoantibodies to a variety of pancreatic islet cell antigens in serum, including insulin.
