Host immune consequences of asymptomatic Trichomonas vaginalis infection in pregnancy.

Journal Article

OBJECTIVE: The purpose of this study was to define the impact of asymptomatic trichomoniasis on lower genital tract neutrophil activation in pregnancy. STUDY DESIGN: In this nested cohort study, pelvic examination was performed on 65 asymptomatic pregnant women between 7 and 22 weeks' with vaginal pH > 4.4. Concentrations of cervical interleukin-8 and alpha-defensin were determined using enzyme-linked immunosorbent assay (ELISA). Trichomonas vaginalis was detected by culture. RESULTS: Median concentrations of vaginal fluid neutrophil defensins and cervical interleukin-8 were significantly greater among women with asymptomatic trichomoniasis (median defensins 18,622 ng/mL, median IL-8 9244 pg/mL) than their uninfected counterparts (median defensins 5144 ng/mL, median IL-8 2044 pg/mL) (P < .001). All women with asymptomatic trichomoniasis had detectable defensin and interleukin-8 concentrations. CONCLUSION: Asymptomatic trichomoniasis in pregnancy is accompanied by a state of neutrophil activation.
