Urinary Tract Infections

Brief summary

RCT to evaluate the safety and efficacy of Lactobacillus reuteri DSM 16666 & Lactobacillus reuteri DSM 17938 to significantly modify the frequency of clinical or bacteriological cure in women with non complicated acute cystitis who receive probiotics for 12 days compared with the frequency in women who receive placebo.

Detailed description

Randomized, double blind, placebo controlled, pilot trial to evaluate the safety and efficacy of L. reuteri in non menopausal women with non complicated cystitis in terms of the frequency of clinical or bacteriological cure. Secondary outcomes will be a) time to clinical/laboratory relapse in at least 70% of women with non complicated acute cystitis who receive probiotics for 12 days compared with the time in women who receive placebo; b) frequency of clinical/laboratory and bacteriologic relapse in women with non complicated acute cystitis who receive probiotics for 12 days compared with the frequency in women who receive placebo, at day 30 after treatment start and c) frequency of adverse related events in women with non complicated acute cystitis who receive probiotics for 12 days compared with the frequency in women who receive placebo. In the active product we will use 5\*10\^8 CFU of Lactobacillus reuteri DSM 16666 & Lactobacillus reuteri DSM 17938 + cranberry extract. The control group will recibe Cranberry extract. The products will be taken twice per day, morning and evening.
