Urinary urobiome modification tied to improvement of urgency urinary incontinence symptoms after taking mirabegron
A recent study by Thomas Halverson and team suggested that longitudinal urobiome modifications are linked to symptom relief in adult women taking mirabegron for urgency urinary incontinence (UUI). The findings were published in the International Urogynecology Journal.
Mirabegron, a beta-3 agonist, is used to treat urge urine incontinence. This study looked at the relationship between symptom improvement and urobiome features in adult women who were given mirabegron for UUI treatment.
The Female Pelvic Medicine and Reconstructive Surgery Centre at Loyola University Medical Centre enrolled UUI patients who chose mirabegron and agreed to take part in this 12-week, open label study. The overactive bladder questionnaire (OAB-Q) and a catheterized urine sample were provided by participants after eligibility screening and research permission. These steps were taken at baseline, 4, 8, and 12 weeks. Based on the validated Patient Global Symptom Control questionnaire score to categorize symptom response (responder vs. nonresponder [PGSC score 3]), the primary outcome, symptom improvement at 12 weeks, was symptom improvement. The Expanded Quantitative Urine Culture (EQUC) procedure was used to process urine samples.
The key findings of this study were:
1. 83 participants—with a mean age of 68 years—completed the baseline evaluation.
2. There were 16 respondents and 31 nonresponders out of the 47 participants whose primary outcome data and sample analyses were available; responder groups shared several demographic characteristics.
3. The majority of subjects had living microorganisms.
4. Between groups, there were no appreciable variations in baseline alpha diversity (within sample).
5. However, during the 12-week follow-up, the responder urobiome had significantly more genera (p = 0.027), was significantly more diversified, and had become significantly wealthier than the nonresponder urobiome.
