DNase in stable cystic fibrosis infants: A pilot study
Journal of Cystic Fibrosis , Volume 2 - Issue 4 p. 183- 188
Objective: To assess the feasibility of measuring short-term effects of inhaled recombinant human deoxyribonuclease (rhDNase, Pulmozyme®) on lung function, pulse oximetry and symptom scores in infants and toddlers with stable cystic fibrosis. Design: Open-label randomized placebo controlled cross-over pilot study. Patients and methods: We treated nine CF patients (0.7-1.9 years) with nebulised rhDNase (2.5 mg) and NaCl 0.9% (10 ml) via jet nebulizer cross-over once daily during 2-week treatment blocks. Measurements were performed at baseline and after treatment blocks and consisted of lung function tests (plethysmography and tidal rapid thoraco-abdominal compression technique), overnight pulse oximetry, and daily symptom scores. Results: DNase treatment and the different assessments were well tolerated by all children and their parents. Lung function showed increased airway patency after treatment with rhDNase (P <0.001), but not after NaCl 0.9%. Overnight pulse oximetry and daily symptom scores did not change during the study period. Conclusions: This pilot study indicates that objective assessment of the effects of rhDNase is feasible in infants with CF who have little or no respiratory symptoms. Our results warrant a larger randomized placebo-controlled trial.
