Nasal Potential Difference (NPD) Protocol in Chronic Rhinosinusitis
NCT02038166 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 20
Last updated 2026-03-17
Summary
The purpose of this study is to determine if acquired (partial) Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) deficiency contributes substantially to the pathogenic mechanisms underlying Chronic Rhinosinusitis (CRS), creating a localized environment that impairs mucociliary clearance (MCC).
