2005-2011年深圳市MSM献血者梅毒/HIV感染调查

目的了解2005-2011年深圳市男男性行为人群（MSM）献血者梅毒/艾滋病病毒（HIV）感染情况,为制订有效阻断输血传播梅毒/HIV策略提供参考依据。方法对深圳市MSM献血者梅毒/HIV监测资料进行统计分析;趋势分析采用Cochran-Armitage趋势检验法。结果近2年内曾经献血的1 320名MSM中,感染梅毒282例,感染率为21.36%;确认感染HIV 80例,感染率为6.06%。梅毒感染率从2005年起快速上升,2009年达到峰值后,维持波动在20%左右;HIV确认阳性率从2006年起迅速上升,2009年达到峰值后,稳定在7%左右;HIV初筛阳性率呈直线上升趋势。结论深圳市MSM献血者梅毒感染率居高不下,HIV感染率逐年增加,应引起有关政府部门足够重视,确保血液安全。

Seroprevalence of syphilis and human immunodeficiency virus among MSM blood donors in Shenzhen from 2005 to 2011

Objective To evaluate the seroprevalence of syphilis/human immunodeficiency virus （HIV） among men who have sex with men（MSM） blood donors （MSMBD） in Shenzhen from 2005 to 2011 and provide scientific evidence for policy making of preventing transfusion-transmitted syphilis/HIV infection. Methods Syphilis/HIV surveillance data were collected about MSMBD from 2005 to 2011 in Shenzhen and analyzed by using Cochran-Armitage trend test. Results A total of 1 320 MSMBD in the recent two years were enrolled, among whom 282 （21.36%） were syphilis positive and 80（6.06~） were confirmed as HIV positive. Syphilis infection rate among MSMBD had increased rapidly since 2005 and reached the highest level in 2009, fluctuating at a rate of around 20%. Similarly the confirmatory HIV infection rate had increased rapidly since 2006 and reached the highest level in 2009, fluctuating at a rate of around 7%, and the positive rate of HIV antibody at the primary screening test tended to rise sharply. Conclusion The infection rate of syphilis among MSMBD in Shenzhen is higher, while the prevalence rate of HIV infection increases annually. The relevant government departments should pay sufficient attention to such situation and ensure the blood safety.
