Chronic bronchial inflammation is an important clinical feature in cystic fibrosis. Approximately 10% of patients with cystic fibrosis suffer from Allergic Bronchopulmonary Aspergillosis. In addition airway inflammation in patients with cystic fibrosis (CF) plays a major role in progression of CF lung disease. In patients with mild disease (Vital capacity >75%) airway inflammation is often under diagnosed.
Severity of allergy against Aspergillus fumigatus will be examined using radioallergosorbent test and skin Prick-test. Subsequently, in patients with established sensitization (RAST ≥ 0.35 IU/mL) a specific bronchial provocation with Aspergillus will be performed. In addition, exhaled nitric oxide,carbon monoxide, exhaled air temperature and inflammatory cells in sputum is measured. 24 hours after bronchial allergen provocation, exhaled NO, CO, air temperature, and bronchial responsiveness is determined and a second sputum obtained.
This study is designed to characterize patients with CF and sensitization against Aspergillus fumigatus in an early stage to prevent pulmonary complications of ABPA. In addition sputum cytokine profiles in CF patients with mild and moderate disease may be different in patients without and with involvement of small airway disease (SAD).

- The characterization of patients with CF and sensitization to Aspergillus fumigatus, and analyzing involvement of small airway disease (SAD) [ Time Frame: 1 year ]
- Aspergillus-induced inflammation in sputum using new mediators (IL-8, IL-13, TLR2 and TLR4, LBP and Chitinasen) with the quantitative PCR and protein assay analysis. [ Time Frame: 1 year ]In addition planned data analyze: CF-patients will be divided according to their involvement of small airway disease (SAD) into 2 groups: Group 1 without SAD with MEF25 > 50%, Group 2 with SAD with MEF25 < 50% and cell counts and pro-inflammatory cytokines (IL-5, IL-6, IL-8, IL-13, IL-17, INF) measured by quantitative RT-PCR and protein assay will be analyzed.
