| Procedures | |
| Data collection method | Samples are taken, respiratory function is assessed and questionnaires are completed during each visit. Immunomonitoring is systematically carried out. Exacerbations caused by viral infections shall be documented by testing for main causal viruses. Identifying predictive exacerbation markers in severe asthmatics may subsequently allow the relevance of treatment based on these markers to be tested, with the aim to prevent exacerbations. |
| Participant monitoring |
Yes |
| Details on monitoring of participants | Monthly follow-up for one year. |
