- The goal of this clinical trial is to learn about medication adherence to difference types of vaginal estrogen in women with low levels of estrogen (for example, post-menopausal women) who have recurrent urinary tract infections. Medication adherence means whether patients take their medicine as prescribed. - Another goal of the study is to learn about changes to the skin of the vagina before and after estrogen treatment, using a specialized imaging modality called optical coherence tomography, which is similar to receiving an ultrasound. - A third goal of the study is to learn about changes to the microbiome (all the bacteria that naturally live in our bodies) before and after treatment with vaginal estrogen. The researchers will be looking specifically at the microbiome in the urine and the vagina. Participants will be assigned by chance (like the flip of a coin) to receive one of three possible vaginal estrogen treatments - cream, tablets, or drug-eluting ring. - The main study tests and procedures include an initial visit in which the researchers will collect baseline information about participants and have participants complete a series of questionnaires. - There will then be 3 and 6 month follow-ups in which the researchers will have participants complete additional questionnaires and the researchers also assess whether participants are using the vaginal estrogen treatment that you were prescribed. If a participant is part of the microbiome cohort, they will also be asked to do the following: - a baseline visit in which urinary and vaginal specimens are collected to assess their baseline microbiome. The vaginal specimen collection will involve a q-tip swab inside the vagina; it is similar to a pap smear. - Finally, participants will have an imaging modality performed on their vagina called optical coherence tomography, which allows the researchers to assess the thickness of the vaginal walls and the blood vessel density. This imaging modality involves the insertion of a thin probe into the vagina to obtain the images of the vaginal wall. - These tests will then be repeated at 6 months to assess if vaginal estrogen treatment causes changes to the vagina.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Adherence to vaginal estrogen treatment | The primary outcome will be the adherence to vaginal estrogen treatment at the 6 month follow-up visit. The 6 month follow-up visit will be the endpoint of the study. We will consider both subjective, patient-reported adherence at 6 months, as well as objective data - tube weight for the estrogen cream, number of tablets left for the estrogen tables, and presence or absence of drug-eluting ring on physical exam for the estrogen ring. | 6 month follow-up visit | |
Secondary | UTI rates | number of culture-proven urinary tract infections | the 6 month duration of the study | |
Secondary | validated patient questionnaire - Urinary Distress Inventory Short Form (UDI-6) | Urinary Distress Inventory Short Form (UDI-6) - six questions, scored from 0 (not at all) to 3 (greatly), with higher scores indicating more distress from urinary symptoms. | Questionnaires will be collected at the baseline visit, 3 month follow-up and 6 month follow-up | |
Secondary | validated patient questionnaires - UTI Symptoms Assessment Questionnaire (UTISA) | UTI Symptoms Assessment Questionnaire (UTISA) - 15 questions, rated from 0 (did not have/not at all) to 3 (severe/a lot), with higher scores indicating a more symptomatic UTI | Questionnaires will be collected at the baseline visit, 3 month follow-up and 6 month follow-up | |
Secondary | validated patient questionnaires - Treatment Satisfaction with Medications Questionnaire (SATMED-Q) | Treatment Satisfaction with Medications Questionnaire (SATMED-Q) - 17 questions, scored from 0 (not at all) to 4 (very much), with higher scores indicating greater satisfaction with medical treatment. | Questionnaires will be collected at the baseline visit, 3 month follow-up and 6 month follow-up | |
Secondary | validated patient questionnaires - Patient Global Impression of Improvement Questionnaire (PGI-I) | Patient Global Impression of Improvement Questionnaire (PGI-I) - one-question with scores from 1 (very much better) to 7 (very much worse0, with higher scores indicating a worsening in symptoms after treatment. | Questionnaires will be collected at the baseline visit, 3 month follow-up and 6 month follow-up | |
Secondary | validated patient questionnaires - Medication Adherence Report Scale (MARS-5) | Medication Adherence Report Scale (MARS-5) - 5 questions, rated from 1 (always) to 5 (never), with a higher score indicating lower medication adherence. | Questionnaires will be collected at the baseline visit, 3 month follow-up and 6 month follow-up | |
Secondary | optical coherence tomography measurements for nested OCT cohort - vaginal epithelial thickness | changes to vaginal epithelial thickness (VET) before and after treatment as measured by vaginal optical coherence tomography (OCT). | baseline and 6 month follow-up visits | |
Secondary | optical coherence tomography measurements for nested OCT cohort - blood vessel density | changes to blood vessel density (BVD) before and after treatment as measured by vaginal optical coherence tomography (OCT). | baseline and 6 month follow-up visits | |
Secondary | Vaginal health index for nested microbiome cohort | vaginal health index (VHI) before and after treatment - The Vaginal Health Index Score is a clinical tool that, by evaluating 5 parameters (vaginal elasticity, vaginal secretions, pH, epithelial mucous membrane, vaginal hydration), allows to obtain a final score defining the degree of atrophy in the genitourinary tract by assigning a single score to each parameter. Total score ranges from 5 to 25, with lower scores corresponding to greater urogenital atrophy | baseline and 6 month follow-up visits | |
Secondary | Vaginal maturation index for nested microbiome cohort | vaginal maturation index (VMI) before and after treatment - microscopic evaluation of the ratio of vaginal epithelial cells (parabasal, intermediate and superficial) | baseline and 6 month follow-up visits | |
