Host Response to Pessaries in Microbial Communities of the Postmenopausal Vagina

Loyola University84 enrolled

Overview

The ability to determine the postmenopausal vaginal environment and the impact of pessary use could help to maximize pessary therapy and non-surgical treatment for such a prevalent problem.

The study will advance the care of elderly patients through providing data to maximize non-surgical options to those at high risk for having surgery and its attending morbidity. In characterizing substantive differences in the vaginal environment of successful and unsuccessful pessary users, the investigators can identify elderly patients at higher risk of adverse events with pessary use as well as novel targets for the pharmacologic treatment of the altered vaginal microbiota and endogenous AMP levels, potentially allowing patients to continue with non-surgical therapies rather than pursuing surgical intervention.

Outcomes

Primary Outcomes

Predominant vaginal microorganisms of older women with and without a pessary

The investigator will collect a vaginal swab specimen in an aerobic and anaerobic preservative tube. Specimens will be sent to the clinical microbiology lab for quantitative culture. Expanded quantitative vaginal culture techniques and matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS).

Time frame: Baseline

Secondary Outcomes

Vaginal antimicrobial peptide (AMP) profile of older women with and without a pessary.

The investigator will collect vaginal lavage fluid (VLF) prior to pessary placement and after vaginal swabs are obtained. Assessing AMP activity using high pressure liquid chromatography fractionation and radial diffusion assay to assess for AMP activity and abundance of candidate AMPs (cathelicidin, beta defensisn (hBD1 and hBD2) psoriasin, lactoferrin).

Time frame: Baseline

Vaginal microbiome and AMP profile between those women that choose to continue pessary use and those that do not by correlating the data from Aim 1 and Aim 2 with the clinical characteristic of continued pessary use.

The investigator will collect vaginal swabs and the Vaginal Lavage Fluid for those subjects who decide to NOT have their pessaries replaced by correlating the data from outcome 1 and outcome 2 with the clinical characteristic of continued pessary use.

Time frame: 3 month visit, 6 month visit
