研究海洛因依赖者中HBV和HCV的流行情况及其感染的相关性因素 ,并探讨降低该人群中HBV及HCV感染率的途径。方法··:采取同期住院的吸毒者入院次日晨空腹血 ,分为两个组 (烫吸组和静脉注射组 ) ,观察两组间HBV -M、抗 -HCV阳性率的差异。结果··:静脉注射组抗 -HCV阳性率和双重阳性率明显高于烫吸组 ,HBV -M则明显低于烫吸组 ,并且静脉注射组内 ,抗 -HCV阳性率表现出随静脉注射毒品时间的延长而明显升高的趋势 (趋势χ2=7.657 ,P<0.01)。结论·· :静脉注射毒品是HCV感染的直接相关性因素 ,吸毒者交叉使用注射器具是造成HCV感染的重要原因。预防以减少静脉注射毒品、减少交叉使用注射器为主。HBV为多途径传播 ,静脉途径传播的重要性相对降低 ,因此预防更加困难 ,需采取综合措施。
To study the prevalence of HBV and HCV in heroin addicts and the related factors of their infection, and to explore ways to reduce the prevalence of HBV and HCV in this population. Methods · · ·: take the same period of hospitalized drug users on the next morning fasting blood, divided into two groups (hot suction group and intravenous injection group) to observe the difference between the two groups HBV-M, anti-HCV positive rate. Results ························································································ Drug duration was significantly increased (trend χ2 = 7.657, P <0.01). CONCLUSIONS: Intravenous drug use is a direct and relevant factor in HCV infection. Cross-contamination of injecting equipment by drug users is a major cause of HCV infection. Prevention to reduce intravenous drug use, reduce cross-use syringes based. HBV is multi-channel transmission, the importance of intravenous route of transmission is relatively lower, so prevention is more difficult, need to take comprehensive measures.
