ABSTRACT
INTRODUCTION AND HYPOTHESIS: We aimed to determine whether the presence of metabolic syndrome (MS) affects the efficacy of mirabegron in treatment-naïve women with overactive bladder (OAB).
METHODS: Women being treated with mirabegron 50 mg were allocated to MS and non-MS groups, and the efficacy of treatment of OAB was compared using the OAB symptom score (OABSS) and a 3-day voiding diary before and 12 weeks after starting treatment. The Wilcoxon signed-rank and Mann-Whitney U tests and multivariate logistic regression were used for statistical analyses, and a p-value < 0.05 was considered to represent statistical significance.
RESULTS: Of the 197 patients who completed the trial, 43 (23.9%) had MS. After 12 weeks of mirabegron treatment, both the MS and non-MS groups showed significant improvements in OABSS score, the number of incontinence episodes/24 h, the number of micturition episodes/24 h, and the number of episodes of urgency/24 h. The factors associated with clinically important differences in OABSS were the presence of hyperglycemia (odds ratio 2.43, 95% confidence interval [CI] 1.05-5.60) and OABSS score at baseline (odds ratio 1.23, 95% CI 1.09-1.39).
CONCLUSIONS: Mirabegron is effective in patients with and without MS, and comorbid hyperglycemia and severe OAB symptoms before treatment are predictors of the efficacy of mirabegron treatment.
