Objectives: The aim of our study was to explore the effectiveness of the combination of D-mannose, Salicin, and Lactobacillus acidophilus (La-14) in patients complaining recurrent symptomatic cystitis due to E. coli.
Materials and methods: From July 2013 to September 2014, 85 consecutive subjects (68 women and 17 men) affected by recurrent symptomatic cystitis were enrolled. Of those, 46 (33 women and 13 men) suffered from neurogenic bladder. Overall 78 patients received an initial 5-days regimen consisting on a tid oral combination of 1000 mg of D-mannose plus 200 mg of dry willow extract (salicin) (attack phase), followed by bid 7-days with 700 mg of D-mannose plus 50 mg (1x109 CFU) of Lactobacillus acidophilus (La-14) (maintenance treatment). The maintenance treatment was repeated every 15 days for the next two months. Patients’ symptoms were evaluated through a 3-days bladder diary and a Visual Analogic Scale (VAS).
Results: After treatment VAS scores decreased from 8.07 ± 1.70 to 4.74 ± 2.07 (p = 0.001) in non-neurological patients (group A) and from 7.21 ± 1.90 to 3.74 ± 3.12 (p = 0.001) in the neurological patients (group B). A significant reduction of daily frequency was noted in both groups: from 14 ± 3 to 7 ± 3 (p = 0.001) in group A and from 15 ± 3 to 8 ± 3 (p = 0.001) in group B. A reduction of incontinence episodes in Group A patients was observed, as well as in 12/39 Group B. Improvements were maintained during follow-up.
Conclusion: This therapeutic approach combining D-Mannose with Salicin (acute treatment) and Lactobacillus acidophilus La-14 (maintaining treatment) seems to be effective in symptomatic bacterial UTIs. Further larger and randomized control trials (RCTs) are needed to confirm our results.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
