Efficacy and Mechanism of High-Dose Vitamin D Supplementation in Pediatric OAB-Dry: A Randomized Clinical Trial Integrating Urinary Myelin Basic Protein as a Theranostic Biomarker

The aim of this study is to give children with dry OAB: (1) Standard behavioral therapy combined with classical anticholinergic drugs (Solinaxine), or (2) standard behavioral therapy combined with short-term high-dose exogenous vitamin D supplementation are used to compare the outcomes of lower urinary tract symptoms in children with dry OAB during follow-up. To provide more robust supporting evidence for the broader promotion of short-term high-dose exogenous vitamin D supplements in combination with standard behavioral therapy as an effective treatment for dry OAB treatment in children.
