According to previous studies, Helicobacter pylori infection is associated with liver disease. In order to better understand the risk of acquiring various liver diseases, we reviewed current knowledge on the impact of H. pylori on the onset, intensification, and progression of various liver diseases caused by the infection of H. pylori. It has been estimated that between 50 and 90% of people worldwide have been infected with H. pylori. The bacterium is mostly responsible for inflamed gastric mucosa, ulcers, and cancers associated with the gastric mucosa. Through the active antioxidant system in H. pylori, the bacteria can neutralize free radicals by synthesizing VacA, a toxin that causes cell damage and apoptosis. Furthermore, there is a possibility that CagA genes may play a role in cancer development. People who have been infected with H. pylori are likely to develop lesions in the skin, the circulation system, and the pancreas. Moreover, transferring blood from the stomach may allow H. pylori to colonize the liver. The bacterium worsened liver function during autoimmune inflammation, toxic injury, chronic HCV infection, chronic HBV infection, and liver cirrhosis. Increasing portal pressure, hyperammonemia, and esophageal varices may be associated with H pylori infection. As a result, it is crucial to diagnose and treat this infection in patients with H. pylori.
根据以往的研究,幽门螺杆菌感染与肝病有关。为了更好地了解感染幽门螺杆菌后发生各种肝病的风险,我们复习了目前关于幽门螺杆菌感染对各种由其引起的肝病的发病、加重和进展影响的知识。据估计,全世界有 50%至 90%的人感染了幽门螺杆菌。这种细菌主要导致胃黏膜发炎、溃疡和与胃黏膜相关的癌症。幽门螺杆菌通过合成 VacA 这种能导致细胞损伤和凋亡的毒素,利用其活性抗氧化系统来中和自由基。此外,CagA 基因可能在癌症发展中发挥作用。感染了幽门螺杆菌的人更有可能在皮肤、循环系统和胰腺中出现病变。此外,从胃部转移的血液可能使幽门螺杆菌定植于肝脏。在自身免疫性炎症、毒性损伤、慢性 HCV 感染、慢性 HBV 感染和肝硬化期间,该细菌会使肝功能恶化。门静脉压力升高、高血氨症和食管静脉曲张可能与幽门螺杆菌感染有关。因此,对感染幽门螺杆菌的患者进行诊断和治疗至关重要。
