Hypoglycemia Caused by Exogenous Insulin Antibody Syndrome: A Large Single-Center Case Series from China.

Predisposing factors for autoimmune hypoglycemia caused by exogenous insulin antibody syndrome include a strong autoimmune background. Susceptible HLA genotypes for type 1 diabetes or insulin autoimmune syndrome might not explain susceptibility to this condition. Additionally, insulin autoantibodies and the insulin/C-peptide molar ratio are reliable screening options. The prognosis for this condition is favorable. Monitoring of insulin and insulin autoantibodies may contribute to treatment effectiveness.
