Objective:
This study aimed to determine the prevalence, subtypes, and control status of chronic rhinosinusitis (CRS) among patients with severe asthma receiving biologic therapy in a tertiary allergy clinic.
Methods:
A single-center, cross-sectional observational study was conducted in adult patients with severe asthma receiving biologics for at least 6 months. CRS diagnosis and control were assessed based on European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 criteria. The Sinonasal Outcome Test-22 (SNOT-22) was also administered. Statistical analyses were performed using appropriate univariate and multivariate methods.
Results:
Among 148 patients with severe asthma receiving biologic therapy, 97 (65.5%) were diagnosed with comorbid CRS. Of these, 68 (45.9%) had CRS with nasal polyps (CRSwNP) and 29 (19.5%) had CRS without nasal polyps (CRSsNP). A total of 54 patients (55.6%) were treated with omalizumab and 43 (44.3%) with mepolizumab. Overall, 32.9% of patients had controlled CRS, 36.0% were partly controlled, and 30.9% were uncontrolled. In multivariable ordinal regression analysis, the presence of N-ERD and higher BMI were associated with poorer CRS control, whereas early-onset asthma and prior maintenance systemic corticosteroid use were associated with better control, suggesting that these factors may be related to CRS control status in this population.
Conclusions:
CRS is highly prevalent among patients with severe asthma receiving biologics, and approximately one-third remain uncontrolled despite treatment. These findings emphasize the importance of regular upper airway assessment and may inform future strategies for optimizing biologic selection and treatment outcomes in this population.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
