Szczegółowy opis
The purpose of this study is to compare lung function values with the Lung clearance index of 20 Patients with Bronchiolitis obliterans aged between 6 up to 28 years. Further we aim to compare the bronchial Inflammation between the patients and a reference group with similar age conditions to determine possible outcome-parameters for following interventional studies.
The sputum samples will be processed and quantitatively analyzed to get a profile of the cytological composition.
(Sputum and serum samples are analyzed by quantitative real-time polymerase chain reaction (PCR) (qRT-PCR) and by cytometric bead assay (CBA).)
Methods and Work Programme:
- Measurement of nitric oxide in expired air (FeNO)
- Lung function testing with spirometry and body plethysmography
- Lung clearance index (LCI)
- Bronchodilation
- Blood test: blood count, CRP, RAST, serum inflammatory mediators, (genetic markers of the non-specific pulmonary defense system)
- Induced sputum for inflammatory mediators and microbiological investigations
