title: Changing paradigms in the diagnosis and management of bronchiectasis.
abstract: The face of bronchiectasis may have changed in recent years but individual cases continue to pose difficult challenges. As childhood infection becomes less of a problem, alternative causes of bronchiectasis are increasingly recognized which themselves offer new problems of diagnosis and management. Evolving concepts of pathogenesis suggest alternative strategies for treatment but as yet the evidence base on which to make firm decisions is lacking. Antibacterial regimens are not universally applicable and individualized protocols with parenteral, nebulized or continuous antibacterial therapy are increasingly used in the treatment of patients with bronchiectasis. Despite the theoretical appeal of using mucolytic or anti-inflammatory drugs their roles are still uncertain and have yet to be examined in adequate clinical trials. The factors determining disease progression are still poorly understood but in some patients worsening airflow obstruction heralds the onset of ventilatory failure. The management of the latter requires bronchodilators and controlled oxygen therapy, and strategies including non-invasive ventilation are increasingly an option. Changing indications for surgery are evident with fewer palliative resections but a developing role for transplantation.
