Swabs of each genitalulcer were processed in a multiplex PCR assay (M-PCR) for simultaneous detection of Herpes simplexvirus (HSV), Treponema pallium, and Haemophilusducreyi. Other STDs were classified by routine diag-nostic criteria, including microscopy or culture forNeisseria gonorrhoeae, Chlamydia trachomatis,Urea- plasma urealyticum, Human papillomavirus,Trichomonas, etc.Results: Of the 8 962 patients with STDs, the HIVseroprevalence in patients with and without GUD was1.75% (5/285) and 1.53% (133/8677), respectively,with no statistically significant difference (χ 2=0.09,P>0.05; OR=1.15, 95%CI=0.47-2.81) . HIVseroprevalence in patients with syphilis, genital her-pes and other STDs was 2.81% (22/784), 0.74% (6/814) and 1.49% (110/7 364), respectively. Prevalencein patients with syphilis was significantly higher thanthat in patients with genital herpes and other STDs,(χ 2=9.92, P<0.005, OR=3.89, 95%CI=1.67-9.05;χ 2=7.66, P<0.001, OR=1.90, 95%CI=1.21-3.00).Conclusions: The study shows that the HIV sero-prevalence in this population of patients with GUDis very low. The results also indicate an associationbetween syphilis and HIV infection. The relationshipbetween genital herpes and HIV infection needsfurther research.展开更多

Method Swabs were collected after exposure to rash andgenital tract during GH relapse or remission on a weekly basisfor four to six weeks. NGU patients with negative chlamydiaand mycoplasma tests were also swabbed for a similarduration. All swabs underwent HSV DNA detection withquantitative PCR. Result: There was a significant difference in the rate ofasymptomatic HSV shedding in urinary tracts comparing GHand the control group and comparing NGU and the controlgroup (P<0.05). The rate of HSV shedding was 22%, 9.8%and 3.3% for GH, NGU and control groups respectively. Therate of HSV shedding was 21.7% (20/92) for patients withactive GH and 23% for those in remission. The HSV positiverate was significantly higher in the group with patients whohad more than six relapses within one year compared to thegroup of patients with less than six relapses.Conclusion: There is HSV subclinical shedding in theirgenital tract during active GH and remission. SubclinicalHSV shedding is more common in patients with more than sixGH relapses per year compared to GH patients with fewerrelapses. Approximately 9.9% of NGU patients with negativechlamydia mycoplasma testing was found to have subclinicalHSV infection.展开更多
