Hepatitis B virus (HBV) and hepatitis delta virus (HDV) are highly prevalent viruses estimated to infect approximately 300 million people and 12–72 million people worldwide, respectively. HDV requires the HBV envelope to establish a successful infection.

2023年7月20日 · Hepatitis D is a liver disease in both acute and chronic forms caused by the hepatitis D virus (HDV) that requires HBV for its replication. HDV-HBV co-infection is considered the most severe form of chronic viral hepatitis due to more rapid progression towards liver-related death and hepatocellular carcinoma.

2024年4月24日 · Hepatitis D is a liver infection caused by HDV. HDV is known as a "satellite virus" because it can only infect people who are also infected by the hepatitis B virus (HBV). HDV can cause severe symptoms and serious illness that can lead to liver damage and even death.

2024年11月4日 · Hepatitis virus type D, also called hepatitis delta or HDV, causes hepatitis D. It needs hepatitis B virus (HBV) to survive and make more copies of itself. You can only get an HDV infection while you already have an HBV infection or at the same time as an initial HBV infection. How do you get hepatitis D?

Hepatitis D virus (HDV), also known as the ‘delta agent’, is a satellite agent of hepatitis B virus (HBV). HDV does not synthezise its own coat; it is enveloped by hepatitis B surface antigen (HBsAg), which occurs as large (L), middle (M) and small or major (S) surface proteins, differing in the length of the amino-terminal extension (Ueda ...

2022年12月15日 · This review includes an overview of the HBV and HDV viruses, including life cycle, structure, natural course of infection, and histopathology. A discussion of the interplay between HDV RNA and HBV DNA during chronic infection is also included.

Hepatitis D is a liver disease caused by the hepatitis D virus (HDV). HDV is known as a “satellite virus,” because it can only infect people who are also infected by the hepatitis B virus (HBV). HDV infection can be acute or lead to chronic, long-term illness.

Co-infection is the simultaneous HBV and HDV acute infection occurring in a susceptible individual. HBV/HDV coinfection is responsible for acute hepatitis resembling acute hepatitis B , which is frequently more severe than acute hepatitis B and provides an increased risk of acute liver failure [60,61].

2022年9月12日 · Hepatitis D virus (HDV) is a unique pathogen that requires the presence of hepatitis B virus (HBV) for its replication and spread. HDV uses the HBV surface antigen as its envelope protein, making it dependent on the coinfection or …

HDV is a defective RNA pathogen requiring the simultaneous presence of HBV to complete its life cycle. Two major specific patterns of infection have been described: the coinfection with HDV and HBV of a susceptible, anti-HBs-negative individual, or …
