Trichomonas Vaginalis Treatment Reduces Vaginal HIV-1 Shedding
January 27, 2009
The researchers wrote that vaginal HIV-1 shedding has been associated with Trichomonas vaginalis (TV) infection and may play a role in HIV transmission. The study's purpose was to determine if effective TV treatment reduces the presence of vaginal HIV-1 RNA.
Fifty-eight women attending an HIV outpatient clinic with resolved TV infection and 92 TV-negative controls who were matched on antiretroviral therapy (ART) were evaluated and interviewed at baseline, one and three months. Most women (81.3 percent) were black; the mean age was 37.5. Their TV status was determined via culture, and the amount of cell-free HIV-1 RNA present in vaginal fluids was determined using the Amplicor HIV-1 Monitor ultrasensitive assay.
At baseline, 46 percent had plasma HIV-1 RNA >10,000 copies/mL; 26.4 percent had CD4
"This study provides additional support that reducing TV infection among HIV-positive women may have an impact on the prevention of HIV transmission," the authors concluded. "Reasons for the delayed treatment effect and the effect on cervical shedding need further investigation."
