HIV-1感染继续在世界范围内传播,主要是通过性交。由于精液是传播HIV-1病毒的主要媒介,我们评估了逆转录酶抑制剂治疗对精液中HIV-1含量的影响。11例HIV-1感染者(IE组)在逆转录酶抑制剂治疗开始前和治疗开始后8~18周采集精液和血液。另11名HIV-1感染男性(即纵向组)的精液和血液在进入研究之前至少2个月没有接受或没有改变抗逆转录病毒治疗,每隔大约2周收集一次,持续10至26周。治疗组治疗8~18周后,82%的精浆HIV-1RNA水平较治疗前下降(中位数下降1.01log10,p=0.003),100%的精浆RNA水平下降(中位数下降0.92log10,p=0.003)。其中5名患者接受了至少52周的随访,1年后精浆HIV-1RNA的中位数水平比基线低0.66log10。在8到18周的随访检查中,所有基线培养阳性的治疗组受试者(50%)每次射精的细菌培养均为阴性或感染单位较低。纵向组的血液和精液中的HIV-1RNA水平在10-26周内没有明显变化。启动逆转录酶抑制剂治疗有效地减少了HIV-1在精液中的脱落,因此可能减少感染在人群中的传播。
HIV-1 infection continues to spread worldwide, primarily through sexual intercourse. Because semen is a major vehicle for transmission of HIV-1, we evaluated the effects of reverse transcriptase inhibitor therapy on the amount of HIV-1 in semen. The semen and blood of 11 HIV-1-infected men (ie treatment group) were collected before the initiation of reverse transcriptase inhibitor therapy and then 8 to 18 weeks after initiation of therapy. The semen and blood of another 11 HIV-1-infected men (ie, longitudinal group), who were not on or had no change in antiretroviral therapy for at least 2 months before study entry, were collected at approximately 2-week intervals for 10 to 26 weeks. In the treatment group, 82% of the seminal plasma HIV-1 RNA levels decreased from baseline after 8 to 18 weeks of therapy (median reduction of 1.01 log 10, p= 0.01), and 100% of the blood plasma RNA levels decreased from baseline over the same period (median reduction of 0.92 log 10, p= 0.003). Five of these patients were followed for at least 52 weeks and had a median seminal plasma HIV-1 RNA level of 0.66 log 10 below baseline at 1 year. All subjects in the treatment group with positive cultures at baseline (50%) had negative cultures or a lower infectious units per ejaculate at the 8-to 18-week follow-up examinations. The HIV-1 RNA levels in blood and semen of the longitudinal group did not change significantly over 10 to 26 weeks. Initiation of reverse transcriptase inhibitor therapy effectively reduces shedding of HIV-1 in semen and may therefore reduce the spread of infection within populations.
