Clinical Trial Summary

Define and characterize the neutrophilic phenotype of severe asthma.

Description:

Neutrophilic asthma (NA) is the asthma phenotype less known, causes a severe disease and does not have a specific treatment. Research on the neutrophilia mechanisms, new neutrophil (NEU) types and bronchial microbiome, can provide an opportunity to better understand the NA pathogenesis.

OBJECTIVES: 1. To describe the clinical characteristics of NA and its sub-phenotypes (SUBSTUDY 1); 2. To determine the NEU types associated with the NA and its sub-phenotypes (SUBSTUDY 2); and 3. To identify the bronchial microbiological flora of the NA, specifically related to lung microbiome and the immune response against Chlamydia Pneumoniae (SUBSTUDY 3).

METHODS: Multicenter prospective study including 100 patients with severe asthma (GINA/GEMA criteria): 50 with non-neutrophilic asthma (<65% NEU in induced sputum [IS]); and 50 with NA (> 64% NEU in IS). SUBSTUDY 1: clinical variables (years of evolution, exacerbations, asthma control test, mini asthma quality of life questionnary), comorbidities (GERD, nasal polyposis, obesity, ASS), pulmonary function (FEV1, exhaled fraction of nitric oxide, total lung capacity, Aspergillus), prick-test and CT scan chest; SUBSTUDY 2 (in IS and plasma): apoptotic index by means NE culture and flux cytometer (Annexin-V-FITC), NEU phenotype by surface markers (CD16, CD66b, CD62L, HLADR, CD177, CD11b, CD63, CXCR2, CXCR4) with density gradient study and determination of cytokines (IL-6, IL-8, IL-17, IL-1, IL-22) by ELISA; SUBSTUDY 3 (in IS): bronchial microbiome for 16 subunit rRNA by Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt), and anti-Chlamydia Pneumoniae Immunoglobuling A by ELISA.
