Recently new evidence about fibroblast growth factor 21 (FGF21) highlights the opportunities to use this molecule in new pharmaceutical formulations to combat type 2 diabetes and metabolic syndrome. It is well known that HIV is per se a condition of insulin resistance and in particular the patient with HIV-related lipodystrophy has a condition strictly related to metabolic syndrome. Lipodystrop...

INTRODUCTION HIV infection and its therapy which can affect their aerobic capacity and health-related quality of life of patients. OBJECTIVE We conducted a cross-sectional study to determine if aerobic capacity and health related quality of life was decreased in HIV-infected patients receiving highly active antiretroviral therapy and comparing patients with and without lipodystrophy. RESEAR...

HIV protease inhibitor-related lipodystrophy is characterized by peripheral fat loss, hyperlipidemia, and insulin resistance. Increased availability of lipid to muscle may be one of the mechanisms that induce insulin resistance. Regional fat, intramyocellular lipid (by (1)H-magnetic resonance spectroscopy), serum lipids, and insulin-stimulated glucose disposal (by hyperinsulinemic-euglycemic cl...

Membranous lipodystrophy represents a peculiar type of fat necrosis that is present in patients with various types of skin disease. It is characterized by the presence of microcysts and macrocysts and is lined by amorphous eosinophilic material with a crenelated arabesque appearance. These findings have been associated with lupus erythematosus, diabetes mellitus, erythema nodosum, trauma, etc. ...

Obesity is characterized by accumulation of excess body fat, while lipodystrophy is characterized by loss or absence of body fat. Despite their opposite phenotypes, these two conditions both cause ectopic lipid storage in non-adipose tissues, leading to lipotoxicity, which has health-threatening consequences. The exact mechanisms underlying ectopic lipid storage remain elusive. Here we report t...

Congenital generalized lipodystrophy (GLD) is a rare autosomal recessive disease characterized by near absence of adipose tissue from birth or early infancy and severe insulin resistance. Since Berardinelli described a very rare case of congenital generalized lipodystrophy, nearly 120 cases have been reported in the literature. We report a case of GLD which, to the best of our knowledge, is the...

IN BRIEF Congenital lipodystrophy is a rare genetic disorder characterized by a near-complete absence of fat cells, hypoleptinemia leading to a voracious appetite, and marked insulin resistance. This article focuses on the known cardiovascular manifestations of patients with congenital lipodystrophy, including cardiomyopathy, cardiac arrhythmias, and accelerated atherosclerosis arising from a m...

Abstract Introduction Dilated cardiomyopathy (DCM) is a condition whose etiologies may be various. DCM with ventricular disfunction frequent complication of chemotherapy. Peripartum characterized by reduced ejection fraction (EF), presenting toward the end pregnancy or in first months after delivery. Lipodystrophy associated to dilated and hypertrophic cardiomyopathy. Material Methods A 28-year...

Insulin resistance is a major factor in the pathogenesis of type 2 diabetes and underpins the strong association between obesity and diabetes. Paradoxically, the metabolic consequences of having 'too much' fat (obesity) are remarkably similar to those of having 'too little' fat (lipodystrophy): a finding that has generated considerable interest in a rare disease. In both cases, excess energy ac...
