Résumé
COPD and brochiectasis are characterized by fixed airway obstruction and chronic cough. The finding of bronchiectasis on HRCT scan in the patient with COPD may indicate the presence of more advanced airway dysfunction, frequent exacerbation and bacterial colonization. The aim of this study to evaluate the incidence of bronchiectasis on high resolution computed tomography [HRCT] scanning in patients with moderate and severe COPD, and to relate this with the presence of lower airway bacterial colonization, exacerbation frequency, severity. This study was carried out on 69 patients diagnosed with COPD. All cases were subjected to through history taking, lung function test, sputum culture, HRCT scan of the chest to diagnose bronchiectasis, All the test were performed in a stable phase. 69 COPD patients, 32 patients had moderate COPD, 37 patients had severe COPD, 33 patients [47, 8%] presented with brochiectasis, [31.3%] of the patients with moderate COPD and 62.2% of the patients with severe COPD with statistically significant difference, the more severe functional impairment [FEV1
