Impact of allergic rhinitis on quality of life in patients with chronic rhinosinusitis.

ABSTRACT

OBJECTIVES: To evaluate the impact of allergic rhinitis (AR) on the quality of life (QoL) in patients with chronic rhinosinusitis (CRS). METHODS: Retrospective cross-sectional study of adult patients with CRS presenting to our clinic between August 2020 and February 2023 was performed. AR was diagnosed based on a positive skin or blood allergy test. Patients' characteristics, AR status, comorbidities, endoscopy scores, and SNOT-22 scores were collected. RESULTS: A total of 514 CRS patients were included, with 265 (51.6 %) patients with AR. CRS patients with AR were younger (p = 0.004), more likely to be female (p < 0.001), and more likely to have asthma (p < 0.001). Polyp status and endoscopy scores did not differ between patients with and without AR. Baseline SNOT-22 scores were slightly worse in the AR cohort (43.6 vs 38.7, p = 0.007), which was mainly secondary to rhinologic (p = 0.002), extrarhinologic (p = 0.007), and ear/facial (p = 0.007) subdomains. Worse rhinologic and extrarhinologic scores were associated with the presence of AR after adjusting for confounding variables (Coef = 1.55, p = 0.011; and Coef = 0.83, p = 0.021 respectively). CONCLUSION: The impact of allergic rhinitis on QoL is mainly on the nasal symptoms. Further studies should look at the role of AR on the QoL of different CRS endotypes; and at the role of AR-specific treatment, such as immunotherapy, on the QoL of patients with CRS.
