Background: Growth hormone (GH) plays an important role in modifying body composition. In acromegaly, a state of chronic GH/IGF-I excess, visceral and ectopic fat mass, especially in the liver, are significantly reduced. The aim of this study was to investigate the impact of GH/IGF-I on hepatocellular lipid content (HCL) and energy metabolism in a non-acromegalic cohort of patients with and without non-alcoholic fatty liver disease (NAFLD).Methods: We pe...

Background: Leptin reduces hepatic lipid content in lipodystrophic and overweight, relatively hypoleptinemic NAFLD patients. However, the underlying mechanism is unknown. In rodents, the anti-steatotic action of leptin is mediated by an increase in VLDL secretion and depends on an intact vagal innervation of the liver.Methods: In this randomized, placebo-controlled, crossover trial, we study the effects of a single metreleptin injection (0.1 mg/kg body w...

Objective: Treatment with metreleptin ameliorates hepatic steatosis in patients with lipodystrophy. The anti-steatotic effect of metreleptin is partially independent of its anorexic action, which suggests a direct effect of metreleptin on hepatic lipid metabolism. However, this mechanism is unknown. Based on previous findings in rodents, we hypothesized that metreleptin reduces hepatic lipid content by stimulating very-low density lipoprotein triglyceride (VLDL1-TG) secretion,...
