In a study of noncystic fibrosis in children who had atelectasis of infectious origin, treatment with DNase led to rapid clinical improvement observed within two hours and radiologic improvement documented within 24 hours. DNase may be an effective treatment for infectious atelectasis in pediatric patients with noncystic fibrosis. Such data does not exist for adult patients, but DNase could be used as a trial of therapy in adults as well. [14]
