| Scientific title | Randomised, double-blind analysis of the usefulness of cranberry syrup versus antibiotic prophylaxis with trimethoprim in infantile recurrent urinary tract infection |
| Study acronym | CSRTUI |
| Study objectives | Given the state of uncertainty about the usefulness of antibiotic prophylaxis in children with vesicoureteral reflux we propose the following hypothesis: 1. How effective is the cranberry syrup in preventing recurrent urinary tract infections in children? 2. What organisms are mainly responsible for recurrent urinary tract infections in patients receiving prophylaxis with cranberry syrup? |
| Ethics approval(s) | Ethical Committee Clinical San Cecilio Hospital-dalucía (Spain), 04/01/2008 |
| Health condition(s) or problem(s) studied | Recurrent urinary tract infection |
| Intervention | Experimental group receive an evening dose of 3 ml of cranberry syrup which ensures a fixed concentration of 36 mg of proanthocyanidins. The administration is done before dinner. If vomiting occurs within 30 minutes after administration, the dose is repeated in full. Standard treatment group receive an standard treatment with trimethoprim at 0.2 ml/kg and masked with red cochineal. Management should be before dinner. If vomiting occur within 30 minutes after administration, the dose is repeated in full. |
