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.

Primary Outcome Measures:
  • Rate of bacterial vaginosis [ Time Frame: 3 months ]
    The primary outcome is the rate of bacterial vaginosis after pessary fitting as measured by OSOM BV blue (Genzyme) and gram stain, measured in women using and women not using Trimo-San gel after pessary fitting

Secondary Outcome Measures:
  • Vaginal symptoms [ Time Frame: 3 months ]
    Vaginal symptoms and effect of vaginal symptoms on pessary wearers measured before and after pessary fitting by questionnaire based on verified vaginal symptoms questionnaire

Enrollment: 184
Study Start Date: September 2009
Study Completion Date: September 2014
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Trimo-San group
Pessary wearers are instructed to apply one fingertip (approx 1 tablespoon) of Trimo-San gel inside the vagina or to the pessary (for women removing and cleaning pessary before reinsertion after cleaning) once nightly
Drug: Trimo-San gel
Pessary wearers are instructed to apply one fingertip (approx 1 tablespoon) of Trimo-San gel inside the vagina or to the pessary (for women removing and cleaning pessary before reinsertion after cleaning) once nightly
No Intervention: Control group
Pessary wearers are informed on standard care of pessary, which includes topical estrogen application if they are using. Pessary wearers do not use Trimo-San gel
