The impact of the use of COL-1492, a nonoxynol-9 vaginal gel, on the presence of cervical human papillomavirus in female sex workers.
This study investigated the effectiveness of a nonoxynol-9 (52.5mg, 3.5%), vaginal gel (Advantage S), in the prevention of human papillomavirus (HPV) infection in female sex workers. We showed by HPV DNA determination in cervico-vaginal rinses a significant increase in multiple (>1) HPV infection in HIV-1 seropositive women compared with HIV-1 seronegative women (OR 4.0, 95% CI 1.3-11.9). We also demonstrated a significant increase in multiple HPV infections in HIV-1 seronegative women using nonoxynol-9 compared with HIV-1 seronegative women using placebo (OR 3.5 95% CI 1.0-11.8). We conclude that the use of nonoxynol-9 did not prevent genital HPV infection and could increase the virus' ability to infect or persist.
