Nonalcoholic fatty liver disease and steatohepatitis in people living with HIV.

: The burden of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) is increasing worldwide. This phenomenon poses a potentially dangerous risk of rise in mortalities caused by cirrhosis and liver cancer. Owing to a complex combination of factors, NAFLD and NASH arise in a majority of people living with HIV (PLWH), but accurate estimates of prevalence differ, depending on sample selection, type of analysis, and data interpretation. The wide range of diagnostic tools used to assess liver steatosis and lack of control groups in many studies further contributes to current difficulties in properly assessing prevalence of these conditions. : Thoroughly scrutinizing the current literature, we compared the prevalence of NAFLD and NASH in PLWH to rates found in the general population. We highlighted strengths and limitations of the studies, in order to determine the effective impact of these medical conditions in PLWH. : The prevalence and progression of NAFLD in human immunodeficiency virus (HIV) infection are reported to be widely variable. HIV infection itself and antiretroviral treatment have been demonstrated to play a role in the development of NAFLD. Larger and more effective studies are needed to evaluate the effects of NASH in PLWH and its progression.
