Antiretroviral therapy can effectively control the replication of HIV, prolong the lifespan of patients infected with HIV, and improve their quality of life.At the same time, non-AIDS-related diseases such as diabetes and chronic liver diseases are increasing day by day.Metabolic associated fatty liver disease (MAFLD) is a chronic progressive liver disease caused by overnutrition and insulin resistance in genetically susceptible individuals. It was formerly known as non-alcoholic fatty liver disease (NAFLD).With the continuous improvement of living standards and the constant change of lifestyles, the incidence of metabolic associated fatty liver disease is gradually increasing. Metabolic associated steatohepatitis (MASH) may further develop into liver cirrhosis, liver failure and hepatocellular carcinoma, and is the third most common cause of liver transplantation. In HIV patients, early identification of significant liver fibrosis and MASH with fibrosis is of vital importance.However, due to the fact that the pathogenesis of liver fibrosis in HIV patients is more complex than that in the general population, it involves multiple factors such as the virus, reverse transcriptase drugs, chronic inflammation, and immune disorders.However, the current clinical research on metabolic-related fatty liver fibrosis in people with HIV is still rather limited.
