Association between aryl hydrocarbon receptor and 4-hydroxynonenal in oxidative stress-mediated chronic rhinosinusitis with nasal polyps
Objective Сhronic rhinosinusitis with nasal polyps (CRSwNPs) is a distinct entity within the chronic rhinosinusitis group of diseases, which are chronic upper airway diseases with several pheno- and endotypes. Oxidative stress plays an important role in the pathogenesis of CRSwNPs. The aim was to as...

| description | Objective Сhronic rhinosinusitis with nasal polyps (CRSwNPs) is a distinct entity within the chronic rhinosinusitis group of diseases, which are chronic upper airway diseases with several pheno- and endotypes. Oxidative stress plays an important role in the pathogenesis of CRSwNPs. The aim was to assess the association between expression of the aryl hydrocarbon receptor (AhR) and 4-hydroxynonenal (4-HNE) in patients with CRSwNPs. Methods The study included 26 patients who underwent endoscopic sinus surgery: Fourteen patients with CRSwNPs, and 12 controls with healthy sinus mucosa. Expression of AhR and 4-HNE was assessed in tissue samples using immunohistochemistry. The level of 4-HNE in serum samples was measured using the ELISA assay. Total oxidative capacity (TOC) was assessed by measuring the peroxidase activity. Results Higher levels of 4-HNE expression were observed in tissues (3, range 1–3 vs. 0, range 0–0 p <0.001) and serum (27.7±11.5 vs 9.8±7.7 pmol/mg, p < 0.001) samples of CRSwNPs patients, as compared to healthy controls. Higher expression of AhR was found in inflammatory cells (plasma cells, lymphocytes, eosinopholes) of CRSwNPs patients, compared to controls (3, range 1–3 vs. 2, range 1–2, p = 0.001). There were no differences in TOC across groups (0.0285±0.0207 vs 0.02, 978±0.0197 µM H 2 O 2 eq., p = 0.848). Patients with bronchial asthma (57%) had abundant eosinophil in tissue samples. Patients with recalcitrant CRSwNPs had higher 4-HNE serum levels, compared to non-recalcitrant cases (27.3 vs 24.2 pmol/mg, p = 0.339). Conclusion Patients suffering from CRSwNPs have oxidative stress–mediated overexpression of AhR, which is linked to a chronic inflammatory response in the paranasal sinus tissues. |
