Abstract

BACKGROUND: Vaginal epithelial abnormalities (VEA) are a common complication associated with pessary use. The objective of this study was to determine if there is a host pro-inflammatory response associated with pessary use and VEA.

METHODS: Patients wearing pessaries for at least two weeks for the management of pelvic organ prolapse and/or urinary incontinence were screened for eligibility. Vaginal swabs were collected from women with VEA (cases) and without VEA (controls). Cases were matched to controls in a 1:3 ratio. Cytokine analysis of the collected samples was performed using multiplex analysis to determine the concentrations of interleukin (IL)6, interferon alpha 2 (IFNα2), tumor necrosis factor alpha (TNFα) and IL1β. A cross-sectional analysis was performed, comparing vaginal cytokine concentrations in women with and without VEA.

RESULTS: We enrolled 211 patients in this analysis: 50 cases and 161 controls. The median concentrations (pg/mL) of the four cytokines for cases and controls respectively were; IL6: 6.7 (IQR <2.9 [the lower limit of detection, LLD]-14.2) and < 2.9 (LLD) (IQR <2.9 [LLD]-5.5), IFNα2: 8.2 (IQR 6.1-13.9) and 7.9 (IQR 3.9-13.6), TNFα: 15.2 (IQR 6.1-30.4) and 4.68 (IQR <2.3 [LLD]-16.3), IL1β 195.7 (IQR 54.5-388.6) and 38.5 (IQR 6.7-154.9). The differences in median cytokine levels were statistically higher in cases for IL6, TNFα, and IL1β (all p < 0.001) compared to controls. Older age (OR: 1.062, 95% CI, 1.015-1.112), lower BMI (OR: 0.910, 95% CI, 0.839-0.986) and presence of VEA at last check (OR: 5.377, 95% CI, 2.049-14.108) were associated with higher odds of having VEA on multivariate analysis.

CONCLUSION: Pro-inflammatory cytokines, specifically IL6, TNFα, and IL1β, are elevated in pessary-wearing patients who have VEA. Additional prospective studies are needed to assess baseline vaginal inflammatory profiles before and after pessary placement to understand VEA formation in pessary patients.
