|Study Type:||Observational [Patient Registry]|
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Target Follow-Up Duration:||1 Year|
|Official Title:||Increasing Vitamin D Serum Levels Reduces Pulmonary Exacerbations in Patients With Cystic Fibrosis|
- FEV1 (by % of predicted) [ Time Frame: Baseline, and then, on average, once a month during trial (at least one year). ]Forced expiratory volume in the 1st second (by spirometry)
- Pulmonary Exacerbations (PEs) [ Time Frame: Average number in a year ]Defined according to the research definition of the EuroCare CF Working Group - the need for additional antibiotic treatment as indicated by a recent change in at least two of the following: change in sputum volume, color or consistency, increased cough, increased malaise, fatigue or lethargy, increased dyspnea, anorexia or weight loss, decrease in FEV1 by ≥10% and/or presence of radiographic changes.
- Days of Hospitalisation (DOHs) [ Time Frame: Average number in a year ]Defined as days of admission to the hospital due to a CF-related complication such as pulmonary exacerbation, intravenous (IV) antibiotic treatment, pancreatitis, distal intestinal obstruction syndrome (DIOS), constipation and gastrointestinal bleeding or IV antibiotic treatment at home or as an outpatient at the CF Center.
- Vitamin D level [ Time Frame: Baseline, and then, on average, once a month during trial (at least one year). ]Serum levels for 25(OH)D
Biospecimen Retention: Samples Without DNA
