An 18-year-old man had cystic fibrosis (CF) and insulin-resistant carbohydrate intolerance characterized by (1) obesity, basal hyperinsulinemia, and hyperglucagonemia; (2) impaired oral glucose tolerance; (3) hyperinsulinemia in response to oral and intravenous (IV) administration of glucose and to IV administration of tolbutamide; (4) exaggerated gastric inhibitory polypeptide secretion following orally administered glucose; (5) diminished sensitivity to insulin administered IV compared with other patients with CF. Both parents also demonstrate basal and stimulated hyperinsulinemia in response to orally administered glucose. The long-term outlook for patients with CF is improving, and more patients are surviving childhood. Thus, it should be recognized that an insulin-resistant form of carbohydrate intolerance may develop in patients with CF with obesity and/or genetic risk factors.
