Local profile of cytokines and nitric oxide in patients with bacterial vaginosis and cervical intraepithelial neoplasia.

Objective: To evaluate the local immune response in patients with bacterial vaginosis (BV) and cervical intraepithelial neoplasia (CIN), as assessed by cytokine and nitric oxide (NO) concentrations.

Study Design: Patients attending for routine gynaecological examination were prospectively enrolled in groups: BV (n=25) diagnosed by clinical criteria, CIN graded I to III (n=35, 6 CIN I, 8 CIN II and 21 CIN III) by histological analysis, and controls (n=15) without clinical and cytological findings. Randomly selected patients within CIN group at grades II or III (n=15) were re-evaluated at 60 days after surgical treatment.
