Implication

This longitudinal cohort study examines immune responses in women, showing sexual activity influences genital inflammation, suggesting new insights for HIV risk.

Key Points

To investigate how recent sexual activity and vaginal product use affect mucosal immune responses in women.
Characterized mucosal immune profiles in HIV-negative adolescent girls and young women (14-19) and adult women (25-35) in KwaZulu-Natal, South Africa.
Collected cervical samples before and after sexual activity and/or vaginal product use.
Measured cervical T-cell activation markers and cytokine levels using flow cytometry and multiplex assays.
Recent sexual activity is associated with decreased levels of several pro-inflammatory cytokines (OR 0.58; p = 0.009).
Bacterial vaginosis is linked to increased genital inflammation (OR 2.38; p = 0.017).
Vaginal product use did not show a significant association with genital inflammation after adjustments (OR 1.63; p = 0.187).
