Overview

Three siblings with congenital lipodystrophy were studied extensively for endocrine abnormalities. A severe disturbance in carbohydrate metabolism was observed. Plasma concentrations of glucagon and insulin were markedly elevated both in the basal state and in response to provocative stimuli. In addition, marked resistance to exogenous insulin and a diabetic oral glucose tolerance test were demonstrated. Lipid metabolism, GH, and ACTH secretion were normal...
Metabolic manifestations of insulin deficiency do not occur without glucagon action.
