ABSTRACT

Background: The combination of the clinical features, HRCT score and echocardiographic evidence of pulmonary
hypertension help assess the prognosis in bronchiectasis. Aim: To test whether pulmonary and cardiac functions associated with bronchiectasis would differ according to its type (cystic versus cylindrical) utilizing HRCT score, PFTs and echocardiography. Patients and Methods: A cross-sectional study of patients with bronchiectasis was conducted at Chest and Internal Medicine Departments at Assiut University Hospital, Egypt. The diagnosis of bronchiectasis type was based on HRCT findings. PFTs, HRCT score and echocardiography were assessed in all cases. Results: We studied 56 patients with bronchiectasis; 31 were cystic (group A) and 25 were cylindrical (group B). Forced vital capacity (FVC%) and Dlco% were significantly lower in group A (P < 0.0001) as compared with group B; whereas FEF 25%-75% and FEV1 (0.04) were lower in group B. Global HRCT score, RVD and SPAP were significantly higher in group A (P = 0.002) and correlated with FEV1% (r = ?0.51), and with SPAP (r = 0.16). Conclusions: Airway obstruction and small airway dysfunction were more significantly seen in cylindrical bronchiectasis. Patients with cystic bronchiectasis had significantly, higher global
HRCT scores, RVD and SPAP. HRCT scores correlate with FEV 1% and SPAP and could be a predictor of future
PH. Routine echocardiographic assessment of patients with bronchiectasis, particularly in those with cystic disease is highly recommended.
