Abstract

Objective: To investigate the long-term prophylactic effect of a vaccine on lower urinary tract infections (UTI) of bacterial and the impact of the intensity of the symptoms on the quality of life (QoL).

Methods: Adult female could be enrolled in this study if they had acute UTI at the enrolment visit and bacterial microbiological count of ≥103 CFU/mL of Escherichia coli.

Results: A total of 21 patients were included. Fifteen days after the administration of a vaccine for 3 months, the number of infections dropped almost to zero. Significant differences were observed in the QoL score (p < 0.05). The safety profile was good.

Conclusions: In patients diagnosed with recurrent UTI and treated for 3 months with the vaccine the number of UTI episodes fell very quickly (15 days), and patients remained free of episodes and improved their QoL significantly for 1 year. These results suggest that bacterial vaccines are a possible effective alternative in the prevention of recurrent UTI.
