Background: To prospectively analyze the efficacy of uromune® in the prevention of uncomplicated recurrent urinary tract infections at 3 and 6 months, and according to gender and menopause.
Methods: From September 2011 to December 2017 uromune® was administered sublingually every 24 h along 3 months to 784 patients with history of three or more uncomplicated urinary tract infections in the 12 months prior to the first visit. The variables analyzed with statistical package system for science version 15.0 were age, gender, number of urinary tract infections with positive urine culture in the first consultation, and 3 and 6 months after the end of treatment. The results with positive urine culture were registered at 3 and 6 months after the end of the treatment according to gender and also in the menopausal group with respect to pre-menopausal women.
Results: Mean age was 73.5 years. 82.7% were women and 94.3% menopausal. The number of episodes of urinary tract infections in the 12 months prior to uromune® were 3 in 37.2%, 4 in 28.1%, 5 in 19.5%, 6 in 9.6%, 7 in 4%, 8 in 1.4%, 9 in 0.1% and 10 in 0.1%. Three months after uromune® 44.1% had 0 urinary tract infections and 27.6% had 1. After 6 months the results were 0 urinary tract infections in 32.3% and 1 in 32.4%. Women had 0 urinary tract infections after 3 months in 45.4% and 1 in 28.5%. At 6 months the female had 0 episodes in 32.7% and 1 in 33.2%. Menopausal women had 0 urinary tract infections at 3 months in 46.5% and 1 in 28% and at 6 months scored 0 episodes in 33.6% and 1 in 32.9%.
Conclusions: Uromune® was highly effective to reduce the number of episodes of urinary tract infections at three and six months of follow-up. Uromune® reduced the number of episodes to zero or one in 71.7 and 64.7% at three and six months with minimal side effects. The best results were observed in women over 50 years old. Sublingual immunoprophylaxis with uromune® could be the treatment of first choice in the prevention of uncomplicated recurrent urinary tract infections according to the sample analyzed.
