Vitamin D₃ Deficiency and its Association with Nasal Polyposis in Patients with Cystic Fibrosis and Patients with Chronic Rhinosinusitis

Abstract

VD3 deficiency seemed to be associated with the presence of nasal polyps in the patients with CRS and in the patients with CF in a similar manner. The lower the level of serum VD3, the more severe the mucosal disease was found in the imaging studies and the more frequent microbial colonization of the patients with CF and the patients with CRS.
