Abstract Abstract Background Non-alcoholic fatty liver disease (NAFLD) ranges from simple steatosis to nonalcoholic steatohepatitis (NASH)leading to fibrosis and potentially cirrhosis, and it is one of the most common causes of liver disease worldwide.NAFLD is associated with other medical conditions suchas metabolic syndrome, obesity, cardiovascular disease and diabetes. Visfatin is an adipocytokine hormone, which exerts an insulin-like effect by binding to the insulin receptor-1, we aim to investigate the correlation between serum Visfatin and both glucose, lipid metabolism and nonalcoholic fatty liver disease in Simple obese children. Methods: This prospective study included 62 children clinically evaluated as obese and 35 apparently healthy children, age and sex matched as controls. Patients were recruited from the emergency department, in-patient wards and out-patient clinics of thepediatric department of EL-Mina University, children's hospital.While controls were collected from healthy school children during day time between September, 2016 and October, 2017. Fasting Visfatin, glucose, hemoglobinA1cand lipid levels were assayed and abdominal ultrasonography was done for detection of NAFLD. Results There was a statistically significant correlation between serum Visfatin level and BMI (p<0.01), cholesterol levels (p< 0.01), triglycerides levels (p< 0.01), LDL levels (p< 0.01), HDL levels (p< 0.01) in both overweight and obese groups. Conclusions: Visfatin plays an important role in regulation of glucose and lipid metabolism, also in inflammation and insulin resistance, suggesting a role in pathogenesis of Non-Alcoholic Fatty Liver Disease (NAFLD). Key words: Non-alcoholic fatty liver disease; metabolic syndrome; Visfatin

Abstract Background Non-alcoholic fatty liver disease (NAFLD), characterized as excess lipid accumulation in the liver which is not due to alcohol use, has emerged as one of the major health problems around the world. The dysregulated lipid metabolism creates a lipotoxic environment which promotes the development of NAFLD, especially the progression from simple steatosis (NAFL) to non-alcoholic steatohepatitis (NASH). Purposeand Aim This review focuses on the mechanisms of lipid accumulation in the liver, with an emphasis on the metabolic fate of free fatty acids (FFAs) in NAFLD and presents an update on the relevant cellular processes/mechanisms that are involved in lipotoxicity. The changes in the levels of various lipid species that result from the imbalance between lipolysis/lipid uptake/lipogenesis and lipid oxidation/secretion can cause organellar dysfunction, e.g. ER stress, mitochondrial dysfunction, lysosomal dysfunction, JNK activation, secretion of extracellular vesicles (EVs) and aggravate (or be exacerbated by) hypoxia which ultimately lead to cell death. The aim of this review is to provide an overview of how abnormal lipid metabolism leads to lipotoxicity and the cellular mechanisms of lipotoxicity in the context of NAFLD.
