慢性肝炎中乙型和丙型病毒混合感染的重症化研究

在慢性肝炎中,乙、丙型病毒性肝炎混合感染相当多见,可使肝炎慢性化、重症化,肝组织损伤加重,肝硬化(LC)和肝癌(HCC)发生率增加1]。本文应用血清学和分子生物学方法对196例肝病患者的血清进行检测,初步探讨了乙型肝炎病毒(Hepatitis B virus,HBV)、丙型肝类病毒(Hepatitis C virus,HCV)的复制状况以及两者间的相互作用与预后的关系。1材料和方法1.1病例受检的196例病例均为2004年1月至2005年7月我院住院及门诊病人,男149例,女47例,年龄15~82岁,其中慢性肝炎(CH)患者139例,肝硬化(LC)患者42例,肝癌(HCC)患者15例。所有病例诊断符合…

Study of Severe Liver Disease in Patients Coinfected with HBV and HCV

To understand the dual infection by Hepatitis B virus (HBV) and Hepatitis C virus (HCV), and the viral interference between HBV and HCV infections, biochemical and virological markers of 196 patients were detected. Among 196 patients tested, 76 patients were only infected by HBV, 72 patients were only infected by HCV, and 48 patients were co-infected by HBV and HCV. There were no striking association of ALT in patients with HBV, HCV or co-infection. The positive rate of HBsAg and HBV DNA in patients with co-infection was obviously lower than that of HBV infection only. These results suggested that disease was more severe in patients with co-infection, prevalence of LC and HCC in patients with co-infection was higher than either infection alone. HBV and HCV inhibit the replication with each other, but HCV seems to suppress HBV replication more evidently.
