ABSTRACT
Objective To explore herpes simplex virus type 2 (HSV-2) infection and associated factors among people participating premarital physical examination in 2013-2014 in Minhang District of Shanghai.Methods During 2013 to 2014,people participating premarital physical examination in Minhang District were interviewed with questionnaire regarding HIV/AIDS related Knowledge,sexual behaviors,etc.Blood samples were collected to detect HIV,HSV-2 and syphilis.Results A total of 2 116 participants were investigated,among which 92 were infected with HSV-2,with a prevalence rate of 4.35％.The HSV-2 infection rates were 3.69％ and 5.01％ for male and female,respectively.Multivariate logistic regression analysis showed that for the males,education level of high school and below (OR=2.47,95％CI:1.195-5.108),fiancee infected with HSV-2 (OR=9.29,95％CI:4.279-20.164) were more susceptible to HSV-2.For the females,aged above 25 years (OR=9.29,95％CI:4.279-20.164),census register of other cities in China (OR =2.19,95％CI:1.091-4.378),education level of high school and below (OR =3.37,95％CI:1.721-6.596),never used condoms (OR =3.45,95％CI:1.265-9.392),fiance infected with HSV-2 (OR =8.46,95％CI:3.700-19.351) were more susceptible to HSV-2.Conclusions The prevalence of HSV-2 among premarital population is relatively low in Minhang District.However,low condom use rate leads to an increase in the risk of HSV-2 infection when either partner infected with HSV-2,suggesting increasing condom use between affianced couples.
ABSTRACT
Objective To investigate the band pattern characteristics of Western bolt (WB) by analyzingthe change of anti-virus antibodies from patients with different clinical stages of human immunodeficiency virus 1 (HIV-1) infection.Methods Antibodies were detected by WB test,CD4+ T cells by flow cytometer.Results Among 208 cases,193 male cases accounted for 92.79％,and 163 cases of men who have sex with men (MSM) accounted for 78.37％.The antibodies against viral protein gp160,gp120,gp41,p66,p51,p31,p24 showed high positive rates,and no significant different was detected across different clinical stages.The positive rate of p55 antibody,encoding by gag gene,was significantly higher in those HIV positive individuals infected via homosexual compared with HIV-1 positive individuals through heterosexual contact (P＜0.05).The 5 common WB bands patterns were as following:all bands①,missing p55②,missing p39③,missing p55 + p39④ and missing p39 + p55 + p17⑤.Primary stage infection group showed the highest appearance rate of all bands (44.2％).Conclusions The WB bands patterns and CD4+ T lymphocyte counts can help to judge immune status,determine disease stages and monitor disease progression.We should take effective measures for the MSM and floating population.
