Abstract
Internationally renowned experts present topics related to obesity, nutrition, and liver disease in this issue. In the first article, the epidemiology of obesity and its association with liver disease are covered. The following two articles focus on the roles that visceral adipose tissue and microbiota potentially play in the pathogenesis of obesity-related liver disease. The next article focuses on the hepatic pathology seen in patients with obesity-related liver disease and those with malnutrition. The next five articles are focused on NAFLD and provide in-depth data on the natural history and treatment strategies for patients with NAFLD. The next six articles deal with the impact of obesity on other liver diseases and on special populations including children and liver-transplant recipients. The final article provides the most updated information regarding genomics and genetic targets that may provide better prognostic and diagnostic biomarkers and more personalized treatment targets for patients with NAFLD. Cutting-edge information in this issue will help readers gain better understanding of the natural history and pathogenesis of primary and secondary liver diseases associated with obesity. As the information about obesity-related liver disease expands, clinicians will be able to provide more targeted therapeutic options for these patients and develop more accurate diagnostic and prognostic biomarkers.
