简要总结

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.

详细描述

Methods:

Over a 2 year period, women in one academic OB/GYN clinic, who are patients of the PI and sub-investigator, with a history of at least one prior episode of BV in the past year, (confirmed via medical records) who currently have BV diagnosed via wet mount and vaginal pH, will be approached during a clinical visit regarding their desire to participate in the trial. If the subject chooses to participate after a thorough discussion of the risks and benefits, she will sign the informed consent and be enrolled in the trial. Subjects will be screened as per the providers' discretion for GC/ CH and trichomonas if it seems indicated per sexual history and/ or has not been screened in the last 3 months. A total of 40 patients will be enrolled; 20 in a shorter (12-week) preliminary study without microbiome analysis, and 20 in a longer (6-month) study including microbiome analysis.

Once enrolled, each subject will be assigned a study number by the research nurse and receive a packet of study materials from a study physician/clinician or the research nurse as well as a "Guide to Completing the BV Trial." This is a booklet containing detailed instructions for each day of the study as well as a diary in which participants will record daily symptoms. Demographic and past medical history information will also be collected at this visit.

On the first day of enrollment, subjects will be screened for BV using the Affirm VPIII test, the wet mount, vaginal pH and Nugent scoring. The Affirm test, wet mount, and vaginal pH will be done in the office, the Nugent scoring will be done by Dr. Vonetta Edwards. Subjects will also complete the vulvovaginal symptoms questionnaire (VSQ). If subjects present with either BV or yeast infection, they will be treated with standard of care. After the initial visit, all subjects will begin to use Balance every day, Restore every other day, and BiopHresh every third day until the completion of the study.

Subjects will return every 6 weeks for the remainder of the study to assess AE/SAE and test for BV the same as at the screening visit. These visits and all other study related visits will be with either the PI or sub-investigator. If the participant is found to have BV at one of these visits they will be treated using standard of care and continue using the system as directed. For subjects in the shorter study, subjects will be screened for BV/yeast, vaginal pH, and Nugent scoring every 6 weeks. For those in the longer study, at 3 months and 6 months, the subject will be rescreened for BV using the Affirm VPIII test, vaginal pH and Nugent scoring, and will complete the VSQ. At the 6 month visit, they will repeat all the same procedures and also have a vaginal swab done for analysis by the Juno Vaginal Microbiome Test. They will also be interviewed to obtain clinical experiences during the trial and will turn in a journal of daily product use and symptoms completed throughout the study. This will be obtained a member of the research team.

结局指标

主要结局

Vaginal microbiome (assessed using the Juno Vaginal Microbiome Test, a next-generation sequencing technology)

时间窗: 6 months

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.

Vaginal pH Levels

时间窗: 6 months

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.

BV recurrence (assessed using Affirm VPIII test, BD Diagnostics)

时间窗: 6 months

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.

次要结局

  • Yeast infections (assessed using the Affirm VPIII test)(6 months)
  • Protocol compliance via qualitative analysis of daily journal entries.(6 months)
