Endocrine complications of the acquired immunodeficiency syndrome.

Acquired immunodeficiency syndrome (AIDS) is a multisystem disorder characterized by defects in the immune system that result in opportunistic infections and neoplasms. While endocrine dysfunction has not been a prominent clinical feature of AIDS, all endocrine glands may be affected by the opportunistic infections and neoplasms or by agents used in their treatment. Adrenal cortical insufficiency related to cytomegalovirus and ketoconazole therapy, hypoglycemia related to pentamidine therapy, and hyponatremia secondary to diverse causes are the most serious endocrine abnormalities that commonly occur. As the numbers of patients with AIDS increase, the development of these and other endocrine complications will occur more often. Because the clinical manifestations of endocrine dysfunction may be nonspecific or subtle, they may be overlooked, particularly in the setting of chronically and severely ill patients. Recognition and prompt therapy for endocrine dysfunction is essential for optimal treatment of these patients.
