• Demographic characteristics

  1 year

Study Arms (2)

Neutrophilic asthma

Patients 18 to 80 years old diagnosed of severe asthma, requiring treatment at least with long acting beta agonists (LABA) + high doses inhaled corticosteroids (ICS) with eosinophil count in blood\<300/mm3. They must be ex-smokers with less than 10 packs-year and no other relevant pulmonary disease.

Diagnostic Test: Induced sputum

Non neutrophilic asthma

Patients 18 to 80 years old diagnosed of severe asthma, requiring treatment at least with LABA+ high doses ICS, with eosinophil count in blood\<300/mm3. They must be ex-smokers with less than 10 packs-year and no other relevant pulmonary disease.

Diagnostic Test: Induced sputum

Interventions

Induced sputum DIAGNOSTIC_TEST

Characterization with flow cytometry of the phenotype of the neutrophils isolated in the sputum, microbiome

Neutrophilic asthma; Non neutrophilic asthma
