Abstract
OBJECTIVES: To present our experience with the long-term preventive effect of immunotherapy with Uro-Vaxom® on recurrent urinary tract infections (UTI) in adult patients. MATERIALS AND METHODS: Retrospective analysis of 79 patients with recurrent UTI treated with Uro-Vaxom. Recurrent UTIs were defined as ≥ 2 infections in 6 months or ≥ 3 in 12 months. Patients received a 6 mg Uro-Vaxom capsule daily for 90 days followed by discontinuation for 3 months and then administration for the first 10 days of subsequent months 7, 8 and 9 as a 'booster' regime. The primary outcome measure was the number of UTIs encountered in the 12 months pre-treatment compared to 12 months post-treatment. RESULTS: There was a significant decrease in the mean number of UTIs in the year following initiation of Uro-Vaxom® compared to the year preceding administration 3.14 versus 1.53 (p < 0.05) respectively. CONCLUSION: Uro-Vaxom represents a safe and effective treatment option for prophylaxis of recurrent UTIs. In the UK, Uro-Vaxom is currently unlicensed. This study adds to a growing body of evidence in favor of non-antibiotic immune-prophylaxis for recurrent UTI.
