福建省某市男男性接触人群相关血清学监测及分析

[目的]对福建省某市男男性接触者(MSM)进行相关血清学监测,了解该人群中艾滋病病毒(HIV)和梅毒等性传播疾病(STDs)的感染状况,为制定干预措施提供依据。[方法]采用方便抽样法对MSM人群进行匿名问卷调查,并抽取静脉血进行HIV抗体、梅毒抗体、乙肝病毒HBsAg及丙肝病毒抗HCV-IgG的检测。[结果]共采血检测MSM159例,结果梅毒抗体TRUST阳性率为12.6%(20/159),TPPA阳性率为25.8%(41/159);HIV抗体阳性率为1.9%(3/159),其中1例同时检出梅毒和HIV抗体阳性,HIV和梅毒累积感染率为27.0%;HBsAg阳性率为12.6%(20/159);未检出抗HCV-IgG。年龄大于25岁是HIV和梅毒累积感染的危险因素。[结论]HIV/STDs在MSM人群中存在局部流行的可能性,应及时采取干预措施,控制其流行及向一般人群的传播。
