Bronchiectasis is a chronic respiratory disease, characterized clinically by a persistent cough, excessive sputum production, bronchial infection, and abnormal and permanent dilatation of the bronchi by radiologically [1]. Its prevalence has increased 40% in the last ten years and bronchiectasis is associated with a high level of morbidity and health care costs [1]. Only in the US, the economic costs have been estimated to be above 630 million dollars per year. Causes include pneumonia, tuberculosis and immune system problems (rheumatoid arthritis, Sjögren Syndrome or inflammatory bowel diseases), which are usually managed by internists.
