Topical treatment of vaginal dryness with a non-hormonal cream in women undergoing breast cancer treatment - An open prospective multicenter study.

ABSTRACT: This open, prospective, multicenter, observational study was performed to investigate the efficacy and safety of a non-hormonal cream in women undergoing breast cancer treatment and experiencing vulvovaginal dryness symptoms. Overall, 128 patients from 22 study centers participated. The cream was applied to the vagina and vulva for 28 days. For the efficacy analysis, changes in subjective symptoms (feeling of dryness, itching, burning, pain independent of sexual intercourse, dyspareunia, urinary incontinence) were evaluated. Additionally, the following objective diagnostic findings were assessed by a physician: thinning of vaginal epithelium, redness, petechiae, and discharge. Safety and tolerability were assessed by evaluating type and frequency of adverse events, including adverse medical device-related effects. The frequency and intensity of all subjective symptoms significantly improved from baseline at 28 days (p<0.0001). Additionally, 21.4% of patients were completely free of symptoms (p<0.0001) and urinary incontinence was improved or eliminated in 30.8% of women. The overall sum score for all four objective findings was significantly improved from baseline at 28 days (p<0.0001). The frequency of petechial bleedings was significantly reduced (p<0.0001). Further, significant decreases in the severity of vaginal epithelium thinning, redness and petechiae were observed (p<0.0001). More than 88% of patients and investigators assessed the efficacy and tolerability as being good or very good. No serious adverse events were documented. This study demonstrates that the investigated cream is an effective and safe non-hormonal, topical option in the treatment of vulvovaginal dryness symptoms in patients undergoing breast cancer treatment for. However, the study duration and follow-up time of 4 weeks as well as the non-randomized trial design are limitations of the study.

Project description:The female climacteric or menopausal process characterised by reduced estrogen, associates with an increased risk of recurrent urinary tract infections (rUTIs) linked to uropathogenic Escherichia coli (UPEC). Clinically, topical vaginal estrogen treatment has a prophylactic effect against such infections. The aim of this study was to investigate, in vitro, the effects of a topical estrogen treatment on vaginal epithelial responses following challenge with E.coli flagellin mimicking an UPEC challenge. Immortalised vaginal epithelial cells (VK2 E6/E7), modelling the vaginal epithelium were treated with either 4 nM 17β-estradiol (E) for seven days, 50 ng/ml E.coli flagellin (F) for 12 h, or 4 nM 17β-estradiol plus 50 ng/ml flagellin (E + F(12 h)). RNA was analysed by microarray gene profiling using the Illumina HumanHT-12 v 4 Expression Beadchip. Following E + F treatments expression of genes encoding host defence molecules including DEFβ4A, DEFB103A, LCN2 as well as those associated with keratinisation eg CNFN and SPRR family genes were significantly enhanced (P < 0.05) compared to either E or F treatments alone. Mutation of estrogen responsive elements (EREs) identified in the DEFβ4 gene promoter abolished the augmented gene expression suggesting estrogen functioned directly through a regulatory mechanism involving ESR1/2. Ingenuity pathway analyses also suggested the pro-inflammatory cytokine IL-17A to regulate the vaginal host defences during infection. Pre-treating VK2 E6/E7 cells with estrogen (4 nM) and challenging with 1L-17A & F (12 h) significantly enhanced DEFβ4, DEF103A and S100A7 expression (P < 0.05). Origins of vaginal IL-17 in vivo remain unclear, but patient biopsies support γδ T cells located within the vaginal epithelium. These data suggest that the vaginal antimicrobial response induced by flagellin activation of Toll-like Receptor 5 cell signalling is augmented following topical estrogen application.

Project description:The aims of this study were to compare 12-week outcomes of single-therapy tolterodine (Detrol LA) extended release to intravaginal estrogen (Estrace) for overactive bladder (OAB) symptoms and characterize 24- and 52-week outcomes in women undergoing combined therapy.A single-site randomized, open-label trial in women with urinary frequency, urgency, nocturia, and/or urgency urinary incontinence symptoms was performed. Fifty-eight participants were randomized to oral tolterodine extended release daily or intravaginal estradiol cream nightly for 6 weeks then twice per week. The primary outcome was change in Overactive Bladder Questionnaire (OAB-q) symptom bother score at 12 weeks. Secondary outcomes included the Health-Related Quality of Life Questionnaire (HRQL) of the OAB-q and a 3-day bladder diary. At 12 weeks, subjects were offered addition of the alternative therapy with follow-up at 24 and 52 weeks.There was no difference in symptom bother score improvement between the tolterodine and intravaginal estradiol groups baseline to 12 weeks (20.6 ± 21.7, -15.8 ± 23.3, respectively, P = 0.45). There was a significant within-group decrease in symptom bother score from baseline to 12 weeks (tolterodine, P < 0.0001, and intravaginal estradiol, P = 0.002). Secondary outcome improvement within groups was noted in the HRQL total, urinary incontinence episodes, and median voiding frequency (all P ? 0.03) in the tolterodine group and in the HRQL total score (P = 0.03) in the intravaginal estradiol group, with no differences between groups. Combined therapy outcomes at 24 and 52 weeks compared with single therapy at 12 weeks revealed significant improvement in symptom bother score in the intravaginal estradiol + tolterodine group at 24 and 52 weeks (20.0 ± 23.9, P = 0.008; -16.7 ± 23.3, P = 0.02, respectively).Significant within-group improvement in OAB-q symptom bother was noted in both the intravaginal estradiol and tolterodine groups for OAB symptoms, with no difference between groups. Greater improvement from 12-week single therapy to 24 and 52 weeks of combined therapy was noted in the group originally assigned to intravaginal estradiol. The role of combined medical therapy for OAB symptoms needs further investigation.
