Clopidogrel induced autoimmune hypoglycemia

Abstract

We report insulin autoimmune syndrome in a diet-controlled type 2 diabetes mellitus patient. She developed recurrent attacks of severe hypoglycemia 1 week after the initiation of clopidogrel. The evaluation revealed high insulin and C-peptide levels consistent with hyperinsulinemic hypoglycemia. The insulin-to-C-peptide ratio was reversed and >50. Anti-insulin antibody titers were highly positive.
