Asthmatic Patients Clinical Trial
Official title:
Development and Validation of a Sputum Biomarker mRNA Panel for the Diagnostic Work-up of Asthma 4.
The main objectives of the study are:
1. To unravel the importance of molecular phenotyping in predicting the response to
antimicrobial therapy with potential anti-inflammatory potency
The investigators have developed a non-invasive technique based on mRNA analysis of induced
sputum that enables us to study airway inflammation in detail. This technique forms the basis
for our current project based on the following hypotheses:
1. Different molecular asthma phenotypes exist: a Th2 phenotype and a non Th2 phenotype as
reported by Woodruff and colleagues (Woodruff PG et al). Sputum mRNA cytokine levels can
be used to diagnose Th2 asthma and discriminate this from non-Th2 asthma.
2. Based on our previous research and preliminary data that non-Th2 asthma can be further
divided in Th17 asthma and Th1+Th2 asthma; besides these, a fourth group without Th2,
Th17 or Th1 characteristics also exist.
3. These subgroups have different responses to anti-microbial therapy with potential
anti-inflammatory potency (macrolides).
