Background: The aerobic vaginitis (AV) is characterized by increased levels of aerobic bacteria, vaginal inflammation and depressed levels of lactobacilli. Objective: The purpose of this study was to investigate the therapeutic efficacy of SilTechTM vaginal softgel capsules, containing new microcrystals of silver monovalent ions, for aerobic vaginitis (AV). Methods: This prospective study enrolled 32 women diagnosed with AV. All recruited women were treated with SilTechTM vaginal softgel capsules once daily for 7 days (one course). Therapeutic efficacy was evaluated based on clinical and microscopic criteria, and cure rates were calculated. Women who were improved (but not cured) received a second course of therapy. Patients classified with clinical and microscopic failure were treated using other strategies. Results: After one course of therapy, 59.2% (19/32) of women were cured, 19.0% (6/32) were improved (but not cured) and 21.8% (7/32) failed to respond to the therapy. After two courses of therapy, clinical improvement was achieved in additional two women. The therapy was very well tolerated, and during the entire study no drop out related to the SylTechTM vaginal capsules treatment was observed; only two patients (6.2%) experienced a mild transient burning after application. Conclusion: SylTechTM vaginal capsules is an effective therapeutic option for patients with AV, and most women with AV were cured with one course of therapy.
