Presentation Transcript

  1. Bronchiectasis Dilated airways with frequently thickened walls

  2. Bronchiectasis: Clinical Note: Bronchiectasis may happen 2/2 COPD or may be a separate process with very similar symptoms Clinical: • Cough (90 %) • Daily sputum production (76%) • Dyspnea (72%) • Hemoptysis (56%) • Recurrent pleurisy

  3. Pathophysiology 2 Prerequisites: • Infectious insult • Impairment of drainage, airway obstruction, and/or a defect in host defense.

  4. Pathophys Continued • Infection: Bacterial, mycobacterial, esp. ABPA central airway bronchiectasis • Airway obstruction: intraluminal tumor, foreign body, lymph nodes, COPD • Immunodeficiency: ciliary dyskinesia, HIV, hypogammaglobulinemia, cystic fibrosis (obstruction and immunodef.)

  5. Note: this table compares primary bronchiectasis with COPD

  6. Characteristic central bronchiectasis 2/2 ABPA

  7. Note characteristic location in the upper lobes and superior segments of lower lobes

  8. Exacerbation

  9. Exacerbation: Etiology +Rx Colonization/infection: • Hemophilus • Pseudomonas • MAI • Aspergillus Very difficult to distinguish colonization from acute infection with these bugs. Psuedomonas colonized more bronchiectasis on CT; increased number of hospitalizations vs H. flu colonization Effect of sputum bacteriology on the quality of life of patients with bronchiectasis. Wilson CB; Jones PW; O'Leary CJ; Hansell DM; Cole PJ; Wilson R Eur Respir J 1997 Aug;10(8):1754-60. Treatment: fluoroquinolone

  10. Prevention • Antibiotics-Controversial: Consider Macrolide TIW Cipro qd X 7-14 D/ month • Bronchial Hygiene, physiotherapy, pulmonary rehab • ?bronchodilators, and steroids • Surgery
