Chronic hepatitis B virus (HBV) infection is considered a global public health problem. It is estimated that at least two billion people have been exposed to HBV, and despite an effective vaccine, 300 million people are chronically infected worldwide. Although the virus is not directly cytopathic, the infection can trigger liver cirrhosis and even hepatocellular carcinoma (HCC). Covalently closed circular DNA (cccDNA) in the nucleus of hepatocytes and the inability of the immune system to eliminate chronic virus infection are the most important mechanisms of chronic HBV infection. Different entities, such as the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD), provide guidelines for the management of this disease. Despite advances in the treatment of chronic HBV infection, including the development of nucleotide and nucleoside analogs, many questions remain. Research continues for the development of new treatment options focused mainly on avoiding a relapse on viral load after therapy discontinuation, with an increased risk of liver disease progression, and an eventual CHC.
