Cranberry for Prevention of Urinary Tract Infections in Multiple Sclerosis Patients (CANNEBERGE)

May 18, 2012 updated by: Rennes University Hospital

Prospective, Randomized, Double-blind, Placebo-controlled Study on Parallel Groups Evaluating the Efficacy and Safety of Cranberry (Vaccinium Macrocarpon) in Prevention of Urinary Tract Infections in Multiple Sclerosis Patients.

Bladder dysfunction occurs at some time in most patients with multiple sclerosis and these patients are prone to have recurrent urinary tract infections. Cranberry has been traditionally used for the treatment and prophylaxis of urinary tract infections but there is no reliable randomized controlled trial demonstrating evidence of cranberry's utility in this disease. The aim of our study is to assess the efficacy and safety of cranberry in the prophylaxis of urinary tract infections in patients with multiple sclerosis with a prospective randomized, double-blind and placebo-controlled clinical trial.

Study Overview

Detailed Description

Bladder dysfunction occurs at some time in 70 to 90% of patients with multiple sclerosis and these patients are prone to have recurrent urinary tract infections (UTI), leading to an important morbidity. Cranberry has been traditionally used for the treatment and prevention of UTI and research suggests that its mechanism of action is preventing bacterial adherence to host cell surface membrane.

However, systematic reviews show the small sample sizes and the poor quality of available trials, determining that there is no reliable evidence of effectiveness of cranberry in UTI prophylaxis. Therefore, to assess whether cranberry is effective in reducing UTI in patients with multiple sclerosis, we have designed a randomized, double-blind, placebo-controlled trial. Efficacy will be evaluated on the time to onset of a UTI in the first year of treatment.
