为了评价静脉注射毒品者(IDUS)中HBV与HIV感染率的差异,本文对IDU人群开展了一项前瞻性研究。 本研究包括240例HBV和HIV血清标志阴性的IDUS。以EIAs法按所编号码,检测HBsAg、抗-HBs和抗-HBc,筛检抗-HIV。EIA法抗-HIV重复阳性者由免疫印迹试验进一步证实。HBV和HIV的感染率由血清转换数除以有血清转换危险的人-年数计算,用Poisson回归法对影响血清转换的多种预测指标进行分析。建立独立的回归模型,计算HIV和HBV的血清转换率。
To assess the difference between HBV and HIV infection rates in IDUs, a prospective study of IDU populations was conducted. This study included 240 IDUS with HBV and HIV seronegative markers. Anti-HIV was screened for HBsAg, anti-HBs and anti-HBc by EIAs according to the serial number. EIA anti-HIV repeat positive by Western blot test further confirmed. Infection rates of HBV and HIV were calculated from the number of seroconversion divided by the number of people with the risk of seroconversion, and Poisson regression was used to analyze various predictors of seroconversion. Establish an independent regression model to calculate the seroconversion rates of HIV and HBV.
