CST1 Predictive Model of Oral Glucocorticoid Therapy Sensitivity for Chronic Rhinosinusitis With Polyps

• Status: Not yet recruiting
• Trial end date: 2025-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Topical and systemic steroids constitute the first choice in medical treatment for nasal polyps. Glucocorticoids sensitivity is significantly correlated with CST1 level in nasal secretions. The goal of this single-arm clinical trial based on a multicenter platform is to test CST1 in patients with chronic rhinosinusitis and nasal polyps before and after oral glucocorticoid therapy. Endoscopic polyp score, Total Nasal Symptom Score(TNSS), SNOT-22 score and other biomarkers are also evaluated before and after the treatment. Researchers will develop a CST1 predictive model of oral glucocorticoid therapy for Chronic Rhinosinusitis with Polyps.
