Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
One hundred children will be included in the study. Baseline parameters will be collected in a healthy interval (visit 1), then the children will be followed up for 1 year. If the patients fulfill the criteria for an exacerbation the children will present in our department. We expect that 44% of the children have an exacerbation. All children will present at a second visit after one year (visit 2).
