Predictive Value of Inflammatory Biomarkers for Mirabegron Response in Women With Overactive Bladder

Overactive bladder (OAB) is associated with systemic chronic inflammation. Indices derived from complete blood count (such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII)) have shown associations with OAB presence. However, whether baseline inflammatory status predicts response to beta-3 adrenergic agonist therapy remains untested. This prospective observational cohort study evaluates the predictive ability of baseline NLR, PLR, and SII for 3-month treatment response to mirabegron 50 mg in women with OAB.
