As a common infectious disease in China, chronic hepatitis B is hepatocyte injury and inflammatory necrosis due to immune response caused by hepatitis B virus (HBV). Helicobacter pylori (Hp) is a Gram-negative helicobacter that colonizes and persists in the human gastric mucosa. In recent years, an increasing number of studies have confirmed the close association between Hp infection and HBV-related liver diseases. This article reviews the articles on Hp infection and HBV-related liver diseases in recent years and discusses the association between Hp infection and HBV-related liver diseases, which shows the association between Hp infection and HBV-related liver diseases. The susceptibility to Hp in chronic hepatitis B patients increases with the progression of hepatitis B, and at the same time, Hp infection may increase the incidence rate of esophageal variceal rupture and hemorrhage and the risk of hepatic encephalopathy in patients with hepatitis B cirrhosis. Therefore, the screening and treatment of Hp infection in patients with HBV-related liver diseases should be taken seriously in clinical practice.
