Probability Sample

Study Population

The attending physician evaluated these patients as having type 2 inflammatory asthma based on factors such as FeNO (fractional exhaled nitric oxide) levels ≥ 20, sputum eosinophils (EOS) percentage ≥ 2%, and/or blood EOS count ≥ 300/μl.

Description

Inclusion Criteria:

Enrolled patients were required to have been on regular ICS-LABA therapy for at least 3-6 months without adequate control. The attending physician evaluated these patients as having type 2 inflammatory asthma based on factors such as FeNO (fractional exhaled nitric oxide) levels ≥ 20, sputum eosinophils (EOS) percentage ≥ 2%, and/or blood EOS count ≥ 300/μl. All children were prescribed with dupilumab during the study period.

Exclusion Criteria:

Patients with conditions other than asthma receiving treatment with dupilumab, individuals currently using other biologics or undergoing sublingual or subcutaneous immunotherapy, active parasitic infections, and children with immunodeficiency were excluded.
