ABSTRACTRecurrent urinary tract infections (UTI) are highly prevalent in postmenopausal women, where vaginal estrogen and prophylactic antibiotics are used for treatment. The etiology of recurrent UTIs is not completely known, but the urinary microbiome is thought to be implicated. Thus, we aimed to compare the “steady state” urinary microbiome in three groups of menopausal women who were all using topically-applied vaginal estrogen: 1) women with recurrent UTIs on daily antibiotic prophylaxis; 2) women with recurrent UTIs not on antibiotic prophylaxis; and 3) age-matched controls without recurrent UTIs. Here we present a cross-sectional analysis of baseline data from 64 women enrolled in a longitudinal cohort study. Catheterized urine samples were collected > 4 weeks after last treatment for UTI. Samples were evaluated using expanded quantitative urine culture (EQUC) and 16S rRNA gene sequencing. With EQUC techniques, there were no significant differences in the median numbers of microbial species isolated among groups (p=0.96), even when considering Lactobacilli (p=0.72). However, there were trends towards different Lactobacillus species between groups. With sequencing the overwhelming majority of urinary samples contained Lactobacilli, with non-significant trends in relative abundance of Lactobacilli among groups. Using a Bayesian regression analysis for compositional data, we identified significant differences in anaerobic taxa that were associated with phenotypic groups. Most of these differences centered on Bacteroidales and the family Prevotellaceae, though differences were also noted in Actinobacteria and certain genera of Clostridiales. Associations between anaerobes within the urinary microbiome and recurrent UTI warrants further investigation.IMPORTANCEIn menopausal women with recurrent urinary tract infections (UTIs) compared to those without, the abundance of Lactobacillus within the urinary microbiome is not significantly different when vaginal estrogen is regularly used. In this population, Lactobacillaceae were identified in 97% of urine samples using culture-independent techniques. However, with expanded urine cultures, women with recurrent UTIs taking daily antibiotics had a disproportionately low amount of L. gasseri/L. acidophilus compared to the other phenotypic groups. These findings support the theory that certain Lactobacillus species may be more important than others in the pathophysiology of postmenopausal recurrent UTIs. Furthermore, when using culture-independent techniques to explore urinary microbiota across phenotypic groups, we identified differences in multiple anaerobic taxa. Taken together, these results suggest that altered ratios of anaerobes and certain Lactobacillus species within the urinary microbiome may be implicated in postmenopausal recurrent UTI.

Intravesical Instillations

Background: Treatment options for refractory recurrent urinary tract infections (UTI) are limited; therefore, we sought to determine if intravesical instillations with heparin effectively treat recurrent UTIs. Methods: Patients at an academic medical center who received intravesical instillations with heparin for recurrent UTIs/chronic cystitis between January 2011 and December 2015 were identified via International Classification of Diseases, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) procedure codes. All cases were analyzed for frequency of UTIs during the treatment phase as well as for the subsequent 6 months after completion of therapy. Demographic, clinical and treatment related factors were then collected from the medical records to draw associations with success or failure of treatment. Results: Thirty-nine women were treated with heparin intravesical instillations for recurrent UTIs. The average age of the cohort was 68.38 years [range 25–88, standard deviation (SD) 12.92], with mean parity 2.38 (range 0–7, SD 1.55) and mean body mass index 27.85 (range 19.5–37.9, SD 4.84). A total of 84.6% completed the recommended 6-week treatment course while 69.2% went on to an additional maintenance phase. Twelve patients (30.8%) had a culture-proven UTI during the treatment phase. In the 6-month follow-up period, 46.2% of patients had at least one UTI with only seven patients (17.9%) meeting criteria for recurrent UTIs (two or more UTIs in 6 months). On univariable assessment, development of recurrent UTIs after completion of instillation therapy was associated with increasing age and vaginal estrogen use during the instillation treatment course. Conclusions: Intravesical instillation with heparin is an effective option to consider for the treatment of refractory recurrent UTIs.

The results of several studies reveal that antibiotics may promote treatment resistance by causing alterations in the intestinal flora. The development of a gut reservoir of resistant bacteria promotes the development of UTIs through autoinfection. This review aims to address clinical reliability, efficacy and safety of long-term treatment with oral D mannose for the prevention of Recurrent Urinary Tract Infections (RUTI) in females. A comprehensive MEDLINE, Embase, Scopus and Cochrane search was performed for English language reports published before December 2018 using the term “recurrent urinary tract infections and D mannose” was carried out. We searched Medline, Embase, Scopus and the Cochrane Register of Controlled Trials from January 2010 to December 2018. Eligible studies did not include non-oral therapy, local (vaginal) treatment in women with recurrent UTIs. We identified eligible original articles. A few limitations of the review are the heterogeneity of the available studies, their different rational and aim, the assumption of D mannose for prophylaxis or treatment of recurrent UTIs. Oral D mannose performs well in the prevention of UTIs recurrences, significant improvement of urinary symptoms was observed, the disease- free time was longer in the groups of patients under prophylaxis with D mannose in comparison with control groups (no treatment, antibiotic prophylaxis, prophylaxis with Proanthocyanidin (PAC) etc. The review has limitations, as the studies are heterogeneous, the meta-analysis requires classifications that can also be arbitrary. Furthermore, single-arm studies are not included. Some of the authors found this evidence inconclusive, which results as a limitation of the study. D mannose prolonged the recurrence-free interval of recurrent UTIs, thus reducing the prolonged or cyclical use of antibiotics, improving clinical symptoms, with a significant difference between treatment and control groups (no treatment, antibiotic prophylaxis, prophylaxis with Proanthocyanidin). However, most clinical trials used an association of different substances commingled with D mannose, dosages and regimens of D mannose were different. For this reason, the evidence of the efficacy of D mannose remains low.

<b><i>Objectives</i></b>: To present our experience with the long-term preventive effect of immunotherapy with Uro-Vaxom® on recurrent urinary tract infections (UTI) in adult patients. <b><i>Materials and Methods</i></b>: Retrospective analysis of 79 patients with recurrent UTI treated with Uro-Vaxom. Recurrent UTIs were defined as ≥ 2 infections in 6 months or ≥ 3 in 12 months. Patients received a 6 mg Uro-Vaxom capsule daily for 90 days followed by discontinuation for 3 months and then administration for the first 10 days of subsequent months 7, 8 and 9 as a ‘booster' regime. The primary outcome measure was the number of UTIs encountered in the 12 months pre-treatment compared to 12 months post-treatment. <b><i>Results</i></b>: There was a significant decrease in the mean number of UTIs in the year following initiation of Uro-Vaxom® compared to the year preceding administration 3.14 versus 1.53 (p < 0.05) respectively. <b><i>Conclusion</i></b>: Uro-Vaxom represents a safe and effective treatment option for prophylaxis of recurrent UTIs. In the UK, Uro-Vaxom is currently unlicensed. This study adds to a growing body of evidence in favor of non-antibiotic immune-prophylaxis for recurrent UTI.

AbstractIntroduction.Recurrent urinary tract infections (rUTIs) after kidney transplantation (KT) are associated with significant decrease in graft survival. There is a growing body of evidence for the pleiotropic effects of vitamin D (VD), including immunomodulatory and antibacterial effect. The number of studies on VD’s pleiotropic effects in kidney transplant recipients (KTRs) however is low. The aim of our study was to assess the influence of VD on the incidence of recurrent UTIs after KT.Methods. The KTRs were tested for 25-hydroxyvitamin D (25VD) between 1.05.2012 and 30.11.2012. Patients within 12 months of transplantation, performed parathyroidectomy, concomitant intake of calcineurin inhibittors and mTOR inhibitors, advanced liver disease and VD supplementation were excluded from the study. Recurrent UTIs were defined as more than 3 episodes of active UTI within the last 12 months of testing for 25VD. Statistical analysis was carried out with SPSS version 22.0 and included descriptive statistics, Mann-Whitney U test. Determination of total 25VD was performed by a validated LC-MS/MS method.Results.A total of 275 patients met the above-mentioned criteria (males 182, females 93). The mean 25VD in patients with rUTIs (n=14) was 51.41±25.17 nmol/L, whereas in the group without rUTIs (n=261) the level was 60.35±23.29 nmol/L. After matching the two groups for seasonal factors (sampling for 25VD in July, August, September) and gender 169 patients were selected, and 11 were with rUTIs. No significant difference was detected in the 25VD level in the two groups (53.30±18.37 vs 49.08±21.04 nmol/L), p=0.342.Conclusions.Despite the higher 25VD in the KTRs without rUTIs, the difference between the two groups remained insignificant.

Abstract Background To prospectively analyze the efficacy of uromune® in the prevention of uncomplicated recurrent urinary tract infections at 3 and 6 months, and according to gender and menopause. Methods From September 2011 to December 2017 uromune® was administered sublingually every 24 h along 3 months to 784 patients with history of three or more uncomplicated urinary tract infections in the 12 months prior to the first visit. The variables analyzed with statistical package system for science version 15.0 were age, gender, number of urinary tract infections with positive urine culture in the first consultation, and 3 and 6 months after the end of treatment. The results with positive urine culture were registered at 3 and 6 months after the end of the treatment according to gender and also in the menopausal group with respect to pre-menopausal women. Results Mean age was 73.5 years. 82.7% were women and 94.3% menopausal. The number of episodes of urinary tract infections in the 12 months prior to uromune® were 3 in 37.2%, 4 in 28.1%, 5 in 19.5%, 6 in 9.6%, 7 in 4%, 8 in 1.4%, 9 in 0.1% and 10 in 0.1%. Three months after uromune® 44.1% had 0 urinary tract infections and 27.6% had 1. After 6 months the results were 0 urinary tract infections in 32.3% and 1 in 32.4%. Women had 0 urinary tract infections after 3 months in 45.4% and 1 in 28.5%. At 6 months the female had 0 episodes in 32.7% and 1 in 33.2%. Menopausal women had 0 urinary tract infections at 3 months in 46.5% and 1 in 28% and at 6 months scored 0 episodes in 33.6% and 1 in 32.9%. Conclusions Uromune® was highly effective to reduce the number of episodes of urinary tract infections at three and six months of follow-up. Uromune® reduced the number of episodes to zero or one in 71.7 and 64.7% at three and six months with minimal side effects. The best results were observed in women over 50 years old. Sublingual immunoprophylaxis with uromune® could be the treatment of first choice in the prevention of uncomplicated recurrent urinary tract infections according to the sample analyzed.

Introduction: We assess the effectiveness of intravesical instillation of hyaluronic acid (HA) and chondroitin sulphate (CS) as a non-antibiotic treatment option for prophylaxis of recurrent urinary tract infections (UTIs) in female patients.Methods: This was a retrospective cohort study involving 7 European institutions. We included patients with recurrent UTIs who received intravesical instillations of Ialuril (IBSA International) (50 mL HA 1.6% and CS 2% solution) between January 2010 and March 2012. Medication schedule, length of follow-up, recurrence infection time, number of UTIs/patients/year, patient quality of life, subjective symptoms score, and treatment-emergent side effects were recorded and analyzed.Results: In total, 157 women (mean age: 54.2 ± 4.1 years) were included in the analysis. All patients had at least 12 months follow-up. After 4 weekly and 5 monthly HA-CS bladder instillations, UTI episodes decreased from 4.13 ± 1.14 to 0.44 ± 0.50 (p = 0.01) at 12 months, while recurrent UTI time prolonged from 94.8 ± 25.1 days to 178.4 ± 37.3 days (p = 0.01) at 12 months. An improvement in symptoms and quality of life was achieved. A medium-depth pain after medication instillation was the most reported side effect. Regression model analysis showed significant risk factors in developing new UTI episodes: being more than 50 years old and having more than 4 UTI episodes per year (OR 3.41; CI 95%; 1.51-7.71, p = 0.003 and OR 3.31; CI 95% 1.51-7.22; p = 0.003, respectively). Retrospective design and lack of a control group represent two main limitations of the study.Conclusions: Restoring glycosaminoglycans bladder layer therapy is a promising non-antibiotic therapy to prevent recurrent UTIs.
