Research advances in chronic hepatitis B complicated by nonalcoholic fatty liver disease / 临床肝胆病杂志

ABSTRACT

Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease around the world, and chronic hepatitis B (CHB) complicated by NAFLD has also become more and more common and is taken seriously by clinical physicians. At present, there is no clear understanding of the clinical features and prognosis of CHB complicated by NAFLD. With reference to related literature on CHB complicated by NAFLD, this article reviews the research advances in the risk factors, biochemistry, virology, histology, and prognosis of CHB complicated by NAFLD. It is pointed out that age, male sex, and metabolic disorders are the risk factors for NAFLD in CHB patients, and patients with CHB complicated by NAFLD have a high risk of liver cirrhosis and hepatocellular carcinoma. However, the effect and mechanism of NAFLD on virus replication and clearance in CHB patients and the effect of HBV infection on the development of NAFLD remain unclear, which will be research hotspots in future.
