Highly standardized cranberry extract supplementation (Anthocran®) as prophylaxis in young healthy subjects with recurrent urinary tract infections.
Several studies have investigated the role of cranberry extract in the prevention of recurrent urinary tract infections (UTIs), on different selected subpopulations at increased risk of UTI. In this registry, we tested the prophylactic effects of an oral supplementation containing a highly standardized cranberry extract (Anthocran®) in young subjects with a previous history of recurrent UTIs, over a 2-months follow-up.



36 otherwise healthy subjects in juvenile age (between 12 and 18 years of age) suffering by recurrent UTIs were enrolled. Participants received either a standard management (SM) (control group, n=17) or SM associated with an oral daily supplementation (supplementation group, n=19). Oral supplementation consisted in one capsule containing 120 mg of cranberry extract (Anthocran®), standardized to 36 mg proanthocyanidins, for 60 days. The effectiveness in the prevention of UTIs was determined by: the number of UTIs evaluated two months before the inclusion in the registry and during the supplementation period; the number of symptom-free subjects during the registry period. Safety considerations and measurement of adherence to treatment were also performed.



The two groups were comparable for age, gender distribution, the days of follow-up and also for the number of UTIs before inclusion. The mean number of UTIs observed during the registry in the supplemented group (0.31±0.2) was significantly lower compared to the control group (2.3±1.3) and to the mean number of UTIs assessed before inclusion (1.74±1.1) (p-value = 0.0001 for both). Moreover, 63.1% of supplemented subjects was symptom-free during the registry period, whereas 23.5% subjects were asymptomatic in the control group (p-value <0.05).



This registry supplement study provides compelling evidence on the efficacy of an oral supplementation, based on a highly standardized cranberry extract (Anthocran®), as prophylaxis in young healthy subjects suffering by recurrent UTIs.
