Acute exacerbations in children's interstitial lung disease

Tijdschriftbijdrage - Tijdschriftartikel

INTRODUCTION: Acute exacerbations (AEs) increase morbidity and mortality of patients with chronic pulmonary diseases. Little is known about the characteristics and impact of AEs on children's interstitial lung disease (chILD). METHODS: The Kids Lung Register collected data on AEs, the clinical course and quality of life (patient-reported outcomes - PRO) of rare paediatric lung diseases. Characteristics of AEs were obtained. RESULTS: Data of 2822 AEs and 2887 register visits of 719 patients with chILD were recorded. AEs were characterised by increased levels of dyspnoea (74.1%), increased respiratory rate (58.6%) and increased oxygen demand (57.4%). Mostly, infections (94.4%) were suspected causing an AE. AEs between two register visits revealed a decline in predicted FEV1 (median -1.6%, IQR -8.0 to 3.9; p=0.001), predicted FVC (median -1.8%, IQR -7.5 to 3.9; p=0.004), chILD-specific questionnaire (median -1.3%, IQR -3.6 to 4.5; p=0.034) and the physical health summary score (median -3.1%, IQR -15.6 to 4.3; p=0.005) compared with no AEs in between visits. During the median observational period of 2.5 years (IQR 1.2-4.6), 81 patients died. For 49 of these patients (60.5%), mortality was associated with an AE. CONCLUSION: This is the first comprehensive study analysing the characteristics and impact on the clinical course of AEs in chILD. AEs have a significant and deleterious effect on the clinical course and health-related quality of life in chILD.
