MSM艾滋病暴露前預(yù)防用藥臨床試驗(yàn)隊(duì)列保持影響因素分析
[Abstract]:Objective to investigate the status of new infection and cohort maintenance in (Men who have Sex with Men,MSM) pre-exposure prophylaxis drug (Pre-exposure Prophylaxis,PrEP) trials and to explore the influencing factors of cohort retention rate in MSM population. Methods in July 2013, HIV negative MSM. was recruited in Chengdu by "snowball" method. Participants were randomly divided into three groups: time group (TDF 300 mg), event group) (TDF 300 mg, once a day for 24 hours before same-sex, plus TDF 300 mg, after same-sex). The ratio of three groups was 1: 1: 1: 1. Follow-up every 3 months, and corresponding blood, physical examination and so on. The queue retention was evaluated and the possible influencing factors were discussed by Cox model. Results the HIV positive conversion rates in time group, event group and blank group were 7.6 / 100 person-years, 12.9 / 100 person-years and 11.0 / 100 person-years, respectively. Compared with the control group, the drug protection rates in the time group and the event group were 31.0% and -17.1.37.5% (123 / 328), and the retention rate of the cohort was 29.9% (98 / 328). Multivariate analysis showed that MSM, 30 to 39 years old (RR=0.66,95%CI:0.48~0.91) and tested for HIV virus (RR=0.61,95%CI:0.44~0.84), had better cohort retention. Conclusion the positive conversion rate of HIV in this study is high, and the effect of PrEP on reducing the new infection of HIV is not obvious. The retention rate of the cohort was low and the shedding occurred mainly at the first follow-up. It is suggested that the MSM, with high, low age and no HIV detection service should be concerned about the management of multiple queue retention strategies.
