Brief Summary

Urinary tract infections (UTIs) account for 5-14% of pediatric emergency department visits annually. At the moment, up to one third of children suffering of acute (UTI) will have a new infection and there is a lack of effective methods for preventing secondary UTIs in young children. Majority of UTIs in children are caused by intestinal bacteria of the patient, mainly E. coli that colonizes gut of the patient. E. coli Nissle is a probiotic strain that has been used successfully for treating acute gastrointestinal infections in children. The strain has also been proved to be safe for infants and young children. E. coli Nissle could be a potential solution for preventing recurrent urinary tract infections in children as it competes with pathogenic bacteria that usually cause UTIs in children. The aim of this study is to evaluate efficacy of E. coli Nissle strain in secondary prevention of urinary tract infections in young children.

Study Arms (2)

Nissle group

EXPERIMENTAL

Intervention will start on the day following the ending of the antimicrobial treatment of the UTI. Patients will receive 1 ml of oral suspension containing 10 E8 CFU/ml of E coli Nissle. Patients under one year of age will receive one daily dose and patients aged more than one year will receive a dose twice daily. Intervention will last for 30 days

Drug: E. coli Nissle

Control group

PLACEBO COMPARATOR

Intervention will start on the day following the ending of the antimicrobial treatment of the UTI. Patients will receive 1 ml of oral syrup consisting of Saccharum 630 mg/g and Aqua purificata 370 mg/g. Patients under one year of age will receive one daily dose and patients aged more than one year will receive a dose twice daily. Intervention will last for 30 days

Other: Placebo control
