Abstract
Nonalcoholic fatty liver disease (NAFLD) is generally characterized by hepatic steatosis by imaging or histology in the absence of secondary causes for hepatic fat accumulation, such as significant alcohol consumption, hepatitis C or other chronic liver disease, hereditary disorders, or steatogenic medications. NAFLD is further subgrouped into nonalcoholic steatohepatitis (NASH) and simple steatosis depending on the histological presence of inflammation with hepatocellular injury in the former (NASH) and lack of hepatocyte injury in the latter. The natural history of simple steatosis is a very slow or no histological progression of simple steatosis. In contrast, NASH can exhibit rapid histological progression and ultimately develop cirrhosis [1, 2]. Accordingly, patients with NASH, but not simple steatosis, have an increased liver-related mortality. However, NAFLD patients as a group have a higher overall mortality compared to matched control populations, with cardiovascular disease being the leading cause of death both subgroups [3–8].
