摘要
目的了解各类肝病患者TT病毒(transfusion-transmitted virus,TTV)的感染率,分析TT病毒与已知肝炎病毒的交叉感染情况,探讨TT病毒与肝硬化、肝癌的关系以及是否是非甲~非庚型肝炎患者的主要致病因子。方法采用微板双探针核酸杂交酶免疫方法对TTV基因扩增产物进行定性检测。结果东营地区不同人群TT病毒阳性率分别为,甲肝患者37.50%(6/16),乙肝患者40.00%(18/45),丙肝患者44.44%(24/54),戊肝患者31.25%(10/32),不明原因转氨酶升高患者25.93%(7/27),肝硬化患者47.06%(24/51),肝癌患者31.91%(15/41)。结论东营地区TT病毒存在与已知病毒性肝炎的合并感染,并且血源性传播肝炎的TT病毒感染率明显高于健康志愿人群。是已知肝炎病毒的辅助因子,并可能是肝硬化潜在的致病因子。
Objective To determine the prevalence of Transfusion-transmitted Virus (TTV) infection in several groups of patients with liver disease and to further determine the cross infection with the known hepatitis virus; Find out the relationship beteen TTV, hepatic cirrhosis and hepatic carcionoma, and whether TTV is the main pathogenic factor of non A-E hepatitis. Methods TTV DNA was determined by using the sandwich hybridization on microplate. Results TTV DNA was detected in 6(37.5%) patients with Hepatitis A, 18(40%) patients with Hepatitis B, 24(29%) patients with Hepatitis C, 7(25.93%) patients with unknown transaminase higher, 24(47.06%) patients with hepatic cirrhosis, 15/41(31.91%) patients with hepatic carcionoma in Dongying region. Conclusion In Dongying region TTV can confected with known viral hepatitis, the prevalence of TTV DNA in blood transfusion hepatitis (HBV/HCV) is significantly higher than it in healthy volunteer. TTV is the cofactor fo other known hepatitis viruses and the causative agent of hepatocirrhosis.
