Total IgE (Immunoglobulin E) and Der p 1 (d1) Specific IgE in Induced Sputum in Patients With Allergic and Non-allergic Asthma

NCT03640936 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 32

No results posted yet for this study

Summary

Asthma is a heterogeneous disease, and specifically the phenotype of non-allergic asthma is not yet well defined. Several studies describe this group of patients as having severe asthma, persistent eosinophilia and poor therapeutic response. Among the theories being considered is the role of local IgE. Objectives: 1) To perform a pilot test to validate the measurement technique and standardize the levels of total IgE and IgE specific to Dermatophagoides pteronyssinus (d1) in the induced sputum of asthmatic patients and healthy volunteers. 2) Correlate local total IgE and specific IgE levels to d1 (sputum and peripheral blood) in patients with allergic and non-allergic asthma. 3) Describe the clinical and inflammatory characteristics of patients with allergic and non-allergic asthma.
