Background Bacterial Vaginosis is the most common vaginal infection in women in their reproductive years and a difficult one to treat. In the United States, the National Health and Nutrition Examination Survey (NHANES), estimated the prevalence of BV was 29 percent in the general population of women aged 14 to 49 years and 50 percent in African-American women. It is characterized by a shift in vaginal flora from an acidic environment due to acid producing lactobacilli to a mixture of anaerobic and facultative microorganisms. BV causes symptoms of vaginal odor, itching, discharge and irritation and can greatly impact a woman's health, quality of life, sexual relations, self-image and well-being. BV has also been associated with an increased risk of preterm labor, STD acquisition and vaginal cuff cellulitis after hysterectomy6. After treatment with antibiotics, recurrences are common. About 15-30% will have recurrence in 3 months7. Normal vaginal flora is lactobacilli dominant. Lactobacilli maintain vaginal pH in the acidic range and keep the growth of BV associated bacteria at low levels. Lactobacilli also produce proteins with bactericidal activity which help to maintain their dominance. Anything that alters the vaginal flora and changes the pH to a more basic environment may increase the risk of BV. Currently, there are many sexual lubricants and vaginal moisturizers available on the market. It has recently been shown that many of these are hyperosmolar and it is thought that hyperosmolar lubricants can be damaging to the epithelium and may alter the pH of the vagina. It is postulated that lubricants and moisturizers may predispose to BV by altering the pH of the vagina. The Flourish Vaginal Care System, by Good Clean Love, includes the following three products: Restore, a 510K-cleared moisturizing personal lubricant that has been on the market for 3 years. It is available without a prescription. It is formulated to bio-match the vaginal secretions of women with L. crispatus-dominated microbiota. Restore has a pH of 3.7 with racemic 1% lactic acid, and is iso-osmolar with serum. It is, therefore, much less likely to alter the acid base balance of the vagina, and therefore less likely to predispose to BV. BiopHresh Vaginal Probiotic Suppository, a Bio Matched probiotic homeopathic formulation which provides a clinically-tested combination of lactobacilli including L. crispatus and other strains found in the most stable vaginal microbiome. Research has shown as many as 30% of women do not naturally produce these critical strains of lactobacilli. Balance Moisturizing Personal Wash is a gentle, pH-balancing cleanser with soothing botanical extracts, formulated with more than 60% premium aloe. It is made without toxic saponifiers found in most bar soaps and OTC cleansers, which tend to disrupt the cell to cell adhesion barrier8. The aim of this study is to determine if Flourish Vaginal Care System aids in re-establishing and maintaining a healthy vaginal microbiome by restoring the vaginal pH in to the acidic range. The healthiest vaginal environments are characterized by optimal acidic vaginal pH levels, the presence of specific strains of lactobacilli. The secondary aim is to determine if the continued use of Flourish will prevent recurrence of BV over a 6 month period. The third aim is to determine what the vaginal microbiome community state type is after 6 months of Flourish use. This study is designed to be a pilot/feasibility study. The study will compare the subjects to a historical recurrence risk7. It will also assess the ability of subjects to comply with the protocol.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Vaginal pH Levels | The first aim of this study is to determine if Flourish Vaginal Care System is able to reduce the vaginal pH to a health level (pH 3.5-4.2) in order to support a healthier vaginal microbiome. | 6 months | |
Primary | BV recurrence (assessed using Affirm VPIII test, BD Diagnostics) | The secondary aim is to determine if the continued use of Flourish will prevent recurrence of BV over a 6 month period. Subjects will be tested every 3 months, or more frequently if symptoms of BV or yeast infection develop. | 6 months | |
Primary | Vaginal microbiome (assessed using the Juno Vaginal Microbiome Test, a next-generation sequencing technology) | This aim is to determine what the composition of the vaginal microbiome is after six months of using the Flourish Vaginal Care System in women who had recurrent BV. This is a one-time sample collection and analysis at the end of the study. | 6 months | |
Secondary | Yeast infections (assessed using the Affirm VPIII test) | A secondary aim is to determine frequency of yeast infections while using the Flourish Vaginal Care System. Subjects will be tested every 3 months, or more frequently if symptoms of BV or yeast infection develop. | 6 months | |
Secondary | Protocol compliance via qualitative analysis of daily journal entries. | A secondary aim is to determine how well study subjects are able to adhere to the study protocol. This is a descriptive analysis to determine how often women follow protocol as described, and what kinds/magnitude of deviations occur. | 6 months |
