Urinary Tract Infections Clinical Trial

Official title: Effects of Flourish HEC Vaginal Care System in Menopausal Women With Recurrent Urinary Tract Infections

Status Recruiting

Clinical Trial Summary

Menopausal women have an increased risk of recurrent urinary tract infections. This is likely due in part to hormonal changes occurring during menopause. As estrogen falls, the vaginal microbiome shifts from a healthy one to a less healthy one. Because the vagina is close to the urethra, this vaginal microbiome shift contributes to a loss of protection against urinary tract infections (UTIs). The investigators are asking whether improving the vaginal microbiome using an over-the-counter vaginal hygiene system can reduce frequency of recurrent UTI in menopausal women.

Clinical Trial Description

Urinary tract infections (UTIs) are caused by microorganisms that enter the urethra and cause inflammation. These infectious microbes can migrate up the urinary tract into the bladder, the ureters, and finally into the kidneys if untreated. UTIs ascending to the kidneys are responsible for up to 100,000 hospitalizations each year, and primarily occur in post-menopausal women or catheterized men. Infection of the urethra or bladder most frequently causes symptoms including frequent and intense urge to urinate, burning sensation during urination, cloudy or bloody urine, and pelvic pain. Infection that progresses to the kidneys most frequently causes symptoms including back or flank pain, fever, chills, and vomiting. The most common treatment for uncomplicated UTIs is oral antibiotics, which are usually effective but have undesirable side effects such as diarrhea and vaginal yeast infection and carry risks to vital organs, including the kidney itself. Repeated use of antibiotics is also the major cause of antibiotic resistance. Therefore, development of an alternative treatment or prevention strategy is desirable. The microbiota of the urogenital tract is abnormal in female patients with recurrent UTI compared with that of healthy women. One known risk factor for UTIs is the loss of lactobacilli in the vaginal flora; physical proximity of the urethral orifice to the vaginal introitus explains the connection. Together, these data suggest there may be a role the vaginal microbiota, particularly lactobacilli, play in maintaining urogenital health and reducing the risk of UTI. The Flourish HEC Vaginal Care System is an over-the-counter vulvovaginal wellness system comprised of three products already commercially available that may help support the environment needed for the healthy microbes to thrive. ("HEC" designates hydroxyethylcellulose, a natural gelling ingredient used in this system, differentiating it from an earlier Flourish system which used aloe gel). Normal premenopausal vaginal flora is lactobacilli dominant. Estrogen drives the maturation and thickening of the vaginal epithelium, including the production of large quantities of glycogen. Glycogen is metabolized to smaller units such as maltose, maltotriose, and dextrans, which serve as the fuel for lactobacilli. Lactobacilli maintain vaginal pH in the acidic range by producing lactic acid; this both supports the lactobacilli and keeps the growth of pathogenic bacteria at low levels. Most Lactobacillus spp., including those associated with the healthiest vaginal environments, produce racemic lactic acid. Lactobacilli also produce proteins with bactericidal activity which help to maintain their dominance. But the primary tool lactobacilli depend on to maintain their competitive advantage is the acidity they produce. Because of this circle of pH and lactobacilli levels, anything that alters the vaginal flora and/or changes the pH to a more basic environment will reduce vaginal lactobacilli levels and may increase the risk of UTI. This circle is especially difficult to break after menopause due to the loss of estrogen which leads to loss of fuel for lactobacilli. Menopausal women with a history of recurrent UTI will be recruited to participate in a clinical trial to determine whether use of a vaginal hygiene system can reduce frequency of UTI. Women in the intervention group will use an over-the-counter kit for six months; these products are already available on the market. Changes in vaginal microbiome, changes in vaginal pH, changes in symptoms of genitourinary syndrome of menopause, and frequency of UTI over the six-month study will be assessed and compared to controls following routine care only. ;
