Abstract

Respiratory disease is a common cause of morbidity and mortality in children with Down's syndrome (DS). Causes range from those problems common to many children with DS, such as a narrow airway or impaired immunity, to rare structural lesions, such as tracheal bronchus. Additionally, other organ systems or extrinsic factors may play a role. A thorough understanding of the range of potential problems will aid in the evaluation and management of children with DS and respiratory symptoms.
