Brief Summary:
The primary objective of this prospective, randomized, controlled study is to assess the effect of Trimo-San vaginal gel on the rate of bacterial vaginosis in women who use pessaries. Women being fitted for a pessary for the first time or not wearing a pessary for \>1 year are recruited in to the study and randomized to using Trimo-San gel daily or not using Trimo-San gel. The investigators use two objective measures of bacterial vaginosis (OSOM BV blue and gram stain) and subjective questionnaires regarding the presence and effect of vaginal symptoms on the pessary user prior to pessary fitting and at 3 months post pessary fitting. The investigators hypothesize that Trimo-San gel with not significantly affect the rate of bacterial vaginosis in pessary wearers as measures by OSOM BV blue and Gram stain, but will have a positive effect on the subjective symptoms experienced by women wearing pessaries.
Detailed Description:
The study population will consist of women who will be fitted for and initiate use of a pessary for relief of pelvic organ prolapse and/or urinary symptoms.
All patients scheduled for pessary fitting/initiation who meet the above inclusion criteria will be asked to participate in the study. They are randomized using opaque envelopes pulled sequentially, which were made originally from a blocked design, stratified to women removing the pessary daily themselves and women not removing the pessary daily themselves. Prior to pessary fitting all women in the study answer a brief questionnaire about their vaginal symptoms. Subjects undergo a vaginal swab for OSOM BV Blue (copyright by Genzyme, SekiSui) and Gram stain testing for Nugent's criteria the presence of bacterial vaginosis. Women are then fitted with and instructed on use of a pessary in the standard fashion by a trained physician at at the study sites.
Women will be randomized to either standard pessary care or to use of TrimoSan gel twice a week (half applicator) to the vagina either with applicator or applying half applicator amount to the surface of the pessary before insertion. If women are using additional vaginal medications such as Premarin this information will be collected but not change their randomization and they will continue to use other indicated vaginal medications as they did before participation in the study (per clinical judgement).
At 2 weeks and 3 month after pessary initiation the patients are seen for an office visit. At both the 2 week and 3 month visit they have repeat testing for bacterial vaginosis using vaginal swab for OSOM BV Blue (copyright by Genzyme) and Gram stain testing. At both the 2 week and 3 month visits they will also answer a questionnaire about their vaginal symptoms and the effect of these symptoms on their distress and lifestyle. This questionnaire is similar to the baseline questionnaire answered before initiation of pessary use, and will include questions about whether these symptoms have changed since initiation of their pessary. At the University of New Mexico site, information is also being collected on sexual function using the PISQ-IR questionnaire and on body image using the modified Body Image Scale at baseline, 2 weeks, and 3 months. At this particular site women will also answer questions about their management of the pessary (e.g. if they take it out for intercourse) surrounding sexual activity.
The recruitment goal for this study is 150 women, with 75 in each group. This was calculated to detect a significant difference in the rate of bacterial vaginosis between the control and study groups (α=0.05), and assuming baseline of bacterial vaginosis to be approximately 10% in the population and increased to 30% by hypothetical risk factors, the sample size needed for each group is 62 for a power of 80%. Assuming a 15% dropout rate after recruitment, we plan to randomize at least 75 patients to the control group and 75 patients to the study group for a total of at least 150 patients. 60 women were recruited for this study at the initial site of Washington Hospital Center in Washington, D.C. This study site closed in June 2012. In January 2013 the study opened at University of New Mexico in Albuquerque, NM. The study is currently opening and running at University of New Mexico with the recruitment goal of 90 women at this institution.
The primary outcome measure will be rate of bacterial vaginosis in the study population, to be compared between the control (non Trimo-San using) and study (Trimo-San using) groups. As part of this analysis, we will also compare the rate of bacterial vaginosis in the control and study groups before and after pessary initiation. Secondary outcomes will include:
* Change in vaginal symptoms as assessed by questionnaire before and after initiation of pessary use
* Change in level of worry or distress about vaginal symptoms as assessed by questionnaire before and after initiation of pessary use.
* Change in vaginal symptoms or distress about these symptoms as assessed by questionnaire based on use or non-use of Trimo-San gel.
* Describe the management of women of their pessary surrounding sexual activity (University of New Mexico only)
* Change in body image or sexual function associated with initiation of the pessary or use of TrimoSan gel (University of New Mexico only)
