NCT06961435

Brief Summary

From January 2019 to February 2025, diagnosed ulcerative colitis(UC) patients and gender- and age-matched normal controls were enrolled from the Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University. Our study aimed to explore the associations of plasminogen activator inhibitor-1 (PAI-1) gene polymorphisms with the risk and clinicopathological characteristics of UC, and to analyze the effects of PAI-1 gene variations on the clinical response of vedolizumab (VDZ) treatment in UC patients.
