What this trial studies

This observational study aims to analyze exhaled breath condensate (EBC) to identify biomarkers associated with pulmonary inflammation and infections in patients with bronchial asthma and cystic fibrosis. By establishing EBC 'breathprints', the researchers hope to correlate these molecular signatures with the severity of lung disease and the presence of specific bacterial infections, particularly from opportunistic pathogens like Pseudomonas aeruginosa. The study will include children and adults with asthma and cystic fibrosis, as well as healthy controls, to validate the effectiveness of EBC as a diagnostic tool. The ultimate goal is to enhance early detection and monitoring of lung conditions in these patients.

Who should consider this trial

Good fit: Ideal candidates include children and adults with moderate or IgE-mediated asthma, cystic fibrosis, or healthy individuals without lung disorders.

Not a fit: Patients with severe lung disorders not included in the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved non-invasive diagnostic methods for monitoring lung health in asthma and cystic fibrosis patients.

How similar studies have performed: Other studies have shown promise in using breath analysis for respiratory conditions, but this specific approach using EBC breathprints is relatively novel.
