5. Study Description
Brief Summary
The study aims to asses the ability of cell tests based on the analysis of the anti-Aspergillus cell responses and identify Aspergillus bronchitis with patients with cystic fibrosis.
In addition, the study will evaluate the contribution of biological classification of aspergillosis according to criteria recently proposed by Baxter et al. compared to the classification used in clinical practice in the hospital of Montpellier.
