慢性肝病中以慢性病毒性肝炎和肝硬变占大多数,目前认为慢性病毒性肝炎的发病与免疫功能失调有关,是由于 T 细胞功能的降低,不能发挥正常的细胞免疫作用,而且帮助性 T 细胞功能的下降,对 B 细胞的辅助作用不足,不能产生足够的抗病毒抗体,致使病毒持续存在,造成长期对肝细胞的损害。再者,由于病毒感染和乙型肝炎表面抗原(HBsAg)的附着或渗入肝细胞内等因 Chronic liver disease in chronic viral hepatitis and cirrhosis accounted for most of the current thought that the incidence of chronic viral hepatitis and immune dysfunction is due to reduced T cell function, can not play a normal cellular immune function, and help T cell function Of the decline, the auxiliary role of B cells is not enough, can not produce enough anti-virus antibodies, resulting in the virus persists, resulting in long-term damage to the liver cells. Furthermore, due to virus infection and hepatitis B surface antigen (HBsAg) attachment or infiltration into the liver cells and other factors
