We describe a 52-year-old male manifesting severe insulin resistance associated with hypereosinophilic syndrome (HES). Diabetes mellitus was initially well-controlled by an oral hypoglycemic agent, and thereafter by human insulin. Due to the progression of hypereosinophilia, hepatosplenomegaly and peripheral lymphoadenopathy, severe insulin resistance associated with diabetic ketoacidosis occurred repeatedly, despite intravenous administration of over 1, 000 U per day of human insulin. A high plasma insulin-binding capacity as determined by Scatchard analysis was consistent with insulin antibody-mediated resistance. The diagnosis of HES was made due to the persistent elevation of eosinophil count and associated liver and cardiac damage. Glucocorticoid therapy successfully achieved both reducing clinical symptoms and improving glycemic control.(Internal Medicine 33: 632-636, 1994)
