【摘要】：目的应用艾滋病病毒(HIV)核酸检测技术,对男男性行为者(MSM)中HIV初筛检测阳性,蛋白印迹试验(WB)确证结果为不确定者和HIV初筛检测阴性者进行筛查,及时诊断MSM中的HIV急性期感染者,尽快启动抗病毒治疗,探索我国MSM中HIV急性期感染筛查诊断和治疗的工作模式。方法 2015年7月至2016年6月,通过方便样本的招募方式,选取天津地区的MSM 2 000人,同时使用艾滋病第三代和第四代快速检测试剂进行平行检测,阴性样本统一进行集合核酸(HIV Pooled PCR)检测,对酶联免疫吸附试验(ELISA)结果为阴性、WB检测结果为阴性和不确定者接受扩增核酸检测(NAAT),结果为阳性者且检测值≤1 000拷贝/mL,进行1-2周随访,并在随后接受核酸和WB检测,阳性检测者检测值1 000拷贝/mL,则重复扩增核酸检测步骤,并最终按照检测结果判定HIV急性期感染者。结果共招募符合条件的调查对象1 914人,第三代和第四代快速检测试剂同时检测出阳性73人。4例WB不确定结果样本经过两次NAAT检测被诊断为HIV感染。通过集合核酸检测发现3例结果为阳性的样本。共6例HIV急性期样本接受抗病毒治疗,6例接受治疗样本的病毒载量分别降至46拷贝/mL、230拷贝/mL、72拷贝/mL、20拷贝/mL、622拷贝/mL和48拷贝/mL。结论使用第三代快速检测试剂开展HIV急性期检测工作仍具有较大实际意义和可行性,同时在日常HIV检测工作中应充分重视和发挥核酸检测,减少MSM在HIV检测过程中,从其WB确证结果不确定到随访至其WB检测结果阳性中间传播HIV的风险。
[Abstract]:Objective to detect HIV positive in (MSM) of men who have sex with men by (HIV) nucleic acid detection technique, and to screen those who are uncertain and negative by Western blot test (WB). To diagnose the acute infection of HIV in MSM, to start the antiviral therapy as soon as possible, and to explore the mode of screening, diagnosis and treatment of HIV infection in MSM in our country. Methods from July 2015 to June 2016, 2 000 MSM samples were recruited from Tianjin area, and the third and fourth generation rapid detection reagents were used for parallel detection. Negative samples were uniformly tested for (HIV Pooled PCR) of aggregate nucleic acids. For those whose (ELISA) results were negative and uncertain, those with positive (NAAT), results and detection value 鈮，
