Recently, the Probiotic Spore Research Center – ANABIO R&D Co., Ltd. collaborated with Hanoi Obstetrics and Gynecology Hospital to conduct the study “Evaluation of the Supportive Efficacy of Bacillus Probiotic Spores (LiveSpo® X-SECRET) in the Treatment of Vaginitis.” The study, led by MSc. Dr. Nguyen Canh Chuong – Director of the Training and Direction Center, Hanoi Obstetrics and Gynecology Hospital, was highly evaluated and officially approved with an “Excellent” rating by the hospital’s review committee on April 26, 2025.
This collaboration marks an important milestone in the application of vaginal-spraying probiotics for supporting the treatment of gynecological diseases in general, offering a sustainable, safe solution while reducing the overuse of antibiotics and antifungal agents in vaginitis management.
This is the first study in the world to demonstrate the safety and outstanding efficacy of an intravaginal Bacillus spore probiotic spray in supporting the treatment and reduction of recurrent vaginitis symptoms in patients with bacterial vaginosis and sexually transmitted infections (STIs). After 28 days of LiveSpo® X-SECRET use combined with standard treatment regimens, the data showed:
- A 5.7-fold reduction in symptoms of inflammation, itching, abnormal vaginal odor, and abnormal vaginal discharge compared to baseline. Notably, the improvement in itching was 3-fold higher, and the improvement in multi-symptom reduction (≥3 symptoms) was 6-fold higher compared to the control group (standard treatment combined with physiological saline spray), contributing to effective symptom control and reduction of recurrence after completing the 7–10 day course of antibiotics/antifungals.
- A 275-fold decrease in Gardnerella vaginalis load and a 2.1-fold increase in Lactobacillus relative abundance compared to the control group, supporting natural restoration of the vaginal microbiota following antibiotic/antifungal therapy.
- A 43–60% reduction in pro-inflammatory cytokines (IL-1β and IL-8) and a 66% increase in vaginal IgA levels compared to the control group, strengthening the local immune barrier and reducing the risk of recurrence.
A key highlight of this study is that LiveSpo® X-SECRET not only rapidly improved clinical symptoms but also helped reduce inflammatory markers and restore the vaginal microbiota, providing a robust foundation for natural and sustainable prevention of vaginitis recurrence. The study was highly evaluated by the review committee for its practical applicability and excellent safety profile. LiveSpo® X-SECRET is potential as an effective supportive solution in gynecological care, contributing to a shift in the management of vaginitis and reducing dependence on antibiotics and antifungal medications
