| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
To investigate the effect of supplementation of a single high dose of vitamin D (100.000 Eh) on the percentage of neutrophils in induced sputum in non-atopic asthmatic patients with a predominantly neutrophilic airway inflammation.
|
|
| E.2.2 | Secondary objectives of the trial |
| To investigate the effect of supplementation of a single high dose of vitamin D on the percentage of eosinophils in induced sputum, extend of sinus disease as measured on CT-sinus, pulmonary function (FEV1), levels of exhaled nitric oxide (NO), quality of life (AQLQ), asthma control (ACQ), SNOT, and adverse events scores in these patients and to identify potential predictors of response. |
