Evaluating the Effectiveness in Supportive Treatment of Vaginitis of Vaginal-spraying Bacillus Probiotic Spore Suspension (LiveSpo X-Secret)

Detailed Summary

Vaginitis is a common reproductive infection in women worldwide, particularly in tropical and underdeveloped countries. Traditional antibiotic treatments can disrupt the balance of beneficial bacteria, requiring repeated use, seriously affecting women's health. Therefore, probiotics are microorganisms that are beneficial to human health when consumed in sufficient amounts, playing an important role in maintaining the balance of the body's microflora, especially in the intestines and vagina. Many studies around the world have proven that probiotic strains belonging to the genera Lactobacillus, Bifidobacterium, Bacillus, and Saccharomyces can help reduce the incidence and severity of bacterial vaginal infections and yeast infections. However, the effectiveness of oral or tablet probiotics is limited due to a slow onset of action and sensitivity to acidic conditions and temperature. In this study, the investigators proposed that vaginal spray probiotics containing Bacillus strains combined with proven stability in both acidic and thermal environments, may be a safe and effective symptomatic treatment for vaginal infections due to pathogenic bacteria, viruses, fungi, and/or flagellates. This probiotic supportive therapy may offer a promising alternative to traditional antibiotic therapy by (i) inhibiting the growth of pathogenic microorganism; (ii) regulating pro-inflammatory cytokines; and (iii) improving vaginal microbiota. The aim of the study is to evaluate the effectiveness of vaginal-spraying Bacillus probiotics in LiveSpo®️ X-SECRET (5 billion CFU/5 mL B. subtilis, B. clausii, and B. coagulans) in preventing and supporting the treatment of vaginal infections. Study Population: The study is being carried out at Hanoi Obstetrics and Gynecology Hospital (Hanoi OGH) and Bac Ninh Center for Disease Control and Prevention (Bac Ninh CDC). The sample size is 120 per each location. Description of Study Intervention: In each location, a total of 120 eligible patients are recruited and divided randomly into 2 groups (n = 60/group/location): Control and Experimental groups. Patients in the Control group received routine treatment and 2-3 times/day 0.9% NaCl physiological saline while patients in the experimental group were treated with LiveSpo X-SECRET 2-3 times/day in addition to the same standard of care treatment. While the standard treatment regimen lasts for 7 days, the probiotic treatment is continually maintained for 28 days. Study duration: 8 months.
