OBJECTIVE: Cranberry extracts have been tested as a nutritional supplementation in the prevention of recurrent lower-urinary tract infections (R-UTIs), with mixed results. This pilot, registry study evaluates the prophylactic effects of oral supplementation with a new well-standardized cranberry extract in patients with R-UTI, over a 2-month follow-up.
PATIENTS AND METHODS: All subjects were suggested to take one capsule containing a cranberry extract (AnthocranTM) for 60 days and were also given lifestyle advice. Clinical outcomes were compared between patients on cranberry extracts and those who don't take this supplementation.
RESULTS: In total, 22 subjects completed the study in each of the two groups. In the cranberry group, the reduction in the frequency of UTI episodes during the study period compared with the two months before the inclusion was 73.3% (p CONCLUSIONS: These preliminary results, obtained in a field-practice setting, indicates the effectiveness and safety of a well-standardized cranberry extract in the prevention of R-UTI.
