Official title
Study to Evaluate the Efficacy and Safety of Colipral® (Probiotic Strain Escherichia Coli 5C (ECP24®)) in the Prevention of Recurrent Cystitis in Menopausal Women: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial
Overview
Recurrent cystitis is a common condition in menopausal women and is associated with impaired quality of life and increased antibiotic use. This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy and safety of Colipral® in preventing recurrent cystitis in menopausal women. Participants will be randomized to receive either Colipral® (probiotic strain Escherichia coli 5C (ECP24®)))or placebo for 12 weeks and will be followed for a total of 24 weeks. The study will assess the occurrence of symptomatic cystitis recurrences confirmed by urine culture, as well as symptoms, quality of life, urinary pain, and antibiotic consumption.
Detailed description
Recurrent cystitis, defined as two or more episodes within 6 months or three or more episodes within 12 months, is particularly frequent in menopausal women because of age-related changes in estrogen levels, the urogenital epithelium, and the microbiota. The gastrointestinal tract is considered an important reservoir of uropathogenic bacteria, and intestinal dysbiosis may contribute to recurrent urinary tract infections.
This study is a randomized, double-blind, placebo-controlled, parallel-group clinical trial designed to evaluate whether Colipral® (probiotic strain Escherichia coli 5C (ECP24®)) reduces the proportion of menopausal women experiencing recurrent symptomatic cystitis compared with placebo during a 24-week follow-up period. Recurrence is defined as the appearance of urinary symptoms compatible with the need for therapy and confirmed by urine culture.
A total of 134 menopausal women with recurrent cystitis will be enrolled and randomized in a 1:1 ratio to receive either Colipral® or placebo. Participants in the active treatment group will receive one capsule daily for 12 weeks, while participants in the control group will receive an identical placebo for the same duration. The follow-up period will continue beyond treatment discontinuation to evaluate the persistence of the preventive effect.
Secondary objectives include evaluation of the number of cystitis episodes, time to first recurrence, antibiotic consumption, urinary pain assessed by the Visual Analogue Scale (VAS), symptom severity, and quality of life assessed using the UTI-SIQ-8 questionnaire.
Interventions
- Dietary supplement Colipral®
Colipral® is a probiotic food supplement in gastro-resistant capsules containing the probiotic strain Escherichia coli 5C (ECP24®). Participants will receive one capsule orally once daily, in the morning or evening, for 12 weeks. - Other Placebo
Matching placebo identical in shape, color, and packaging to Colipral®, administered orally as one capsule daily in the morning or evening for 12 weeks.
Primary outcome measures
- Proportion of Participants With at Least One Episode of Symptomatic Cystitis [Time frame: 24 weeks]
Secondary outcome measures (5)
- Time to First Recurrence [Time frame: 24 weeks]
- Number of Total Cystitis Episodes [Time frame: 24 weeks]
- Antibiotic Consumption [Time frame: 24 weeks]
- Urinary Pain [Time frame: 24 weeks]
- Quality of Life and Symptom Severity [Time frame: 24 weeks]
