Abstract

alanine transaminase aspartate transaminase co-infection HBeAg HBsAg Hepatitis B virus hepatitis D virus hepatocellular carcinoma superinfection
Infection by hepatitis B virus (HBV) and hepatitis D virus (HDV) is a major health threat worldwide. In 2019 approximately 296 million individuals were living with a chronic HBV infection. Globally, a chronic HBV infection is the most common risk factor for developing hepatocellular carcinoma (HCC), a leading cause of cancer-related mortality. HDV is a satellite virus of HBV and requires the HBV surface protein for genome packaging and transmission. Individuals with pre-existing chronic HBV infection who contract HDV, resulting in an HDV superinfection, have an increased risk of developing a chronic HBV/HDV infection, which greatly increases the risk of developing HCC compared to a chronic HBV infection. This chapter will describe the molecular biology, clinical features and pathogenesis, epidemiology, and methods to detect HBV and HDV. Infection-prevention strategies, current therapies, and mechanisms that could link a chronic HBV or HBV/HDV infection to HCC development will also be discussed.
