Abstract

Abstract Background Urinary tract infections (UTIs) are prevalent, especially among women as approximately 50% of all healthy women will encounter at least one episode of UTI during their lifetime. An estimated 25%-35% of them will experience a recurrence within the following year. Prolonged antibiotic therapy for prophylaxis of UTI poses the risk of antimicrobial resistance, alteration of normal flora, and high costs to the patient. D-mannose, a polysaccharide may reduce UTI by preventing the adherence of bacteria to uroepithelium by binding to the type1 pili and saturating the adhesin FimH. D-mannose is commonly marketed for urinary tract health and is touted to contribute to better antimicrobial management within primary care settings. We performed an updated meta-analysis comparing prophylaxis with D-mannose versus placebo or no treatment for prevention of recurrent UTI in adult women. Methods We systematically searched PubMed, Scopus, and Cochrane Central databases for trials comparing D-mannose versus placebo or no treatment for UTI prophylaxis in adult women. Outcomes of interest included one or more episodes of UTI within 6 months of randomization and adverse events. Statistical analysis was performed using R software. Heterogeneity was assessed using I2 statistics. The analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline (Figure 1). Risk estimation for recurrent UTI Results The systematic review…
