Abstract
Lipodystrophy includes a wide group of diseases characterized by reduction, absence, or altered distribution of adipose tissue. Lipodystrophies are classified into generalized or partial, according to the fat distribution, and congenital or acquired, considering the etiology. Impaired glucose and lipid metabolism are typically present, thus severe insulin resistance, diabetes mellitus, dyslipidemia, and hepatic steatosis are frequent complications. Because of the rarity and the diversification of lipodystrophies, diagnosis might be challenging, typically for partial forms that cannot be easily recognized, leading to progression of the several metabolic abnormalities associated. First management of lipodystrophy is diet and lifestyle changes, followed by the treatment of metabolic complications. Replacement therapy with metreleptin, currently available in the USA and Europe, has shown improvement of metabolic profile in a great number of patients with lipodystrophy. The purpose of this review was to describe the phenotypic characteristics of all the known lipodystrophic types and to present specific steps for obtaining an early diagnosis and assessing the best treatment of lipodystrophy.
