Abstract

INTRODUCTION AND HYPOTHESIS:

Urinary tract infections (UTIs) are considered the most common bacterial infections, especially in women. The objective of this study was to evaluate the use of the sublingual bacterial vaccine Uromune® in order to prevent recurrent UTIs (RUTIs).

METHODS:

This study was conceived as a multicenter observational study. The clinical history of 319 women who presented at least 2 episodes of UTI in the last 6 months or 3 in 12 months was reviewed. Data related to treatment and clinical evolution were recorded and analyzed. A total of 159 patients received prophylactic treatment with Uromune® for a period of 3 months (group A) and 160 with sulfamethoxazole/trimethoprim 200/40 mg/day for a period of 6 months (group B). Uromune® contained an inactivated bacterial cell suspension of selected strains of Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, and Enterococcus faecalis.

RESULTS:

Patients in group A experienced a highly significant reduction in the number of infections compared to patients in group B. In the first 3 months, the mean number of infections was 0.36 versus 1.60 (P < 0.0001), respectively. A significant reduction was also observed after 9 and 15 months (P < 0.0001). The numbers of patients who did not have any UTI at 3, 9, and 15 months were 101, 90, and 55 in group A versus 9, 4, and 0 in group B (P < 0.0001).

CONCLUSIONS:

The results obtained in this study favor the use of this bacterial-based therapeutic vaccine as an effective strategy to reduce frequency, duration, severity, and costs of RUTIs.
