    Abstract:
    Patients with type 1 diabetes and poor metabolic control can develop hepatomegaly due to intrahepatic glycogen deposition. If these patients also have elevated liver enzymes, dyslipidemia, cushingoid features and delayed growth or sexual maturation, Mauriac syndrome can be diagnosed. This disorder is common and reversible with optimization of insulin therapy. We report three adolescents with type 1 diabetes and a long-standing history of poor glycemic control, who developed hepatomegaly, elevated liver enzymes and dyslipidemia with preserved liver function. One of these patients also had delayed growth and another had hypogonadotropic hypogonadism. Liver ultrasound showed changes suggestive of glycogenosis. In all three patients, optimization of insulin therapy achieved good glycemic control and reversed the manifestations within 2 weeks. The etiology of Mauriac syndrome is controversial since both prolonged hyperglycemia and hyperinsulinization produce glycogen accumulation in the liver. Hypercortisolism (due to ketosis or hypoglycemia) contributes to glycogen storage and also causes growth and sexual maturation delay.
