目的检测重庆市静脉吸毒人群中艾滋病病毒(HIV)新近感染状况并计算HIV发病率。方法收集重庆市两个监测哨点自1999—2006年以来的监测样本共计4711份,通过酶联免疫和蛋白印迹实验检测出HIV-1感染的样本,再应用Ig-G-捕获HIV-1 BED-发病率酶联方法(BED- CEIA),检测其中的新近感染样本,进而估算该人群的HIV-1发病率。结果共检出HIV-1阳性样品130份。哨点A 2001—2005年HIV感染率分别为0.73%、2.02%、1.54%、2.96%、2.80%,发病率分别为0.57%、0.93%、0、1.24%、1.68%;哨点B 2004—2006年HIV感染率分别为4.21%、9.96%、8.13%,发病率分别为0.95%、1.04%、0.90%。虽然两个哨点在发病率方面都有起伏,但差异无统计学意义,感染率与发病率变化趋势一致。结论目前在重庆市监测哨点发现的HIV感染者大部分为既往感染者,发病率维持在较稳定的范围。
Objective To detect the recent HIV infection among the intravenous drug users in Chongqing and calculate the incidence of HIV. Methods A total of 4,711 surveillance samples collected from two monitoring sentinel sites in Chongqing since 1999-2006 were collected. Samples of HIV-1 infection were detected by enzyme-linked immunosorbent assay (ELISA) and western blotting, and Ig-G-capture of HIV-1 BED - incidence of enzyme-linked method (BED-CEIA), detection of newly infected samples, and then to estimate the incidence of HIV-1 in this population. Results A total of 130 HIV-1 positive samples were detected. The sentinel A rates of HIV infection in 2001-2005 were 0.73%, 2.02%, 1.54%, 2.96% and 2.80%, respectively, and the incidence rates were 0.57%, 0.93%, 0,1.24% and 1.68% The rates of HIV infection in 2006 were 4.21%, 9.96% and 8.13% respectively, with the incidence rates of 0.95%, 1.04% and 0.90% respectively. Although both sentinels have ups and downs in the incidence rate, but the difference was not statistically significant, the infection rate and the trend of change consistent. Conclusion Most of the HIV-infected persons found in the surveillance sentinel sites in Chongqing are mostly formerly infected with the incidence maintained at a relatively stable range.
