Cytokine profile in genital tract secretions from female adolescents: impact of human immunodeficiency virus, human papillomavirus, and other sexually transmitted pathogens.

Abstract

Quantitative enzyme-linked immunosorbent assays were used to measure interleukin (IL)-2, IL-10, and IL-12 in cervical secretions from female adolescents with and without sexually transmitted infections. Compared with human immunodeficiency virus [HIV]-negative patients, HIV-positive patients had higher concentrations of IL-10 (118.2 pg/mL vs. 34.5 pg/mL; P=.002) and IL-12 (175.5 pg/mL vs. 85.1; P=.03). IL-2 concentrations were not statistically different. Furthermore, genital tract infections were predictors of IL-10 and IL-12 concentrations. Coinfection with HIV and human papillomavirus predicted the highest IL-10 concentrations; coinfection with HIV, human papillomavirus, and other sexually transmitted pathogens predicted the highest IL-12 concentrations. The data indicate that concomitant infection of the genital tract with HIV and other viral, bacterial, or protozoan pathogens influences the local concentrations of some immunoregulatory cytokines.
