ABSTRACT
BACKGROUND AND OBJECTIVE:
Several bacterial immunisations have been developed to reduce the socioeconomic burden of urinary tract infections (UTIs) and the use of prophylactic antibiotics in the management of recurrent UTIs (rUTIs). This systematic review evaluates the effectiveness of vaccinations in preventing rUTIs.METHODS:
Medline, Embase, and Web of Science were searched from inception to December 2023. Data were collected from cohort studies with a comparator arm and randomised controlled trials (RCTs) investigating vaccination efficacy in adult rUTI patients according to predefined selection criteria (PROSPERO registration CRD42022356662). A pooled analysis took place for RCTs, with a subgroup analysis for vaccine types and booster regimens. Other studies were synthesised narratively. The risk of bias was assessed using Cochrane Risk-of-Bias tools. The Grading of Recommendations, Assessment, Development, and Evaluations framework evaluated the quality of evidence. KEY FINDINGS ANDLIMITATIONS:
Fourteen comparative studies were selected, including 2822 patients across five vaccination types. The pooled risk ratio of eight placebo-controlled studies of the percentage of patients UTI free in the short term (6-12 mo) was 1.52 (95% confidence interval [CI] 1.05-2.20) with a number needed to treat of 6.45 (95% CI 2.80-64.80). There is substantial heterogeneity and a slight risk of a publication bias. CONCLUSIONS AND CLINICAL IMPLICATIONS There is limited evidence to suggest that vaccinations are effective at reducing UTI recurrence in adult female patients in the short term. Owing to low quality of evidence, the literature requires further long-term RCTs with large sample sizes utilising standardised definitions for conclusive evidence of the long-term efficacy of vaccination in rUTI prevention. PATIENTSUMMARY:
We explored whether vaccines could help stop urinary tract infections (UTIs) from happening again. The latest information shows that these vaccines are safe and may help lower the chances of women getting UTIs again for about 6-12 mo.
