- W4312891306 abstract "<b>Aim:</b> To assess the survival rate and risk factors associated with mortality in patients with non-CF bronchiectasis (NCFB). <b>Methods:</b> During 2014-2019 we prospectively enrolled HRCT confirmed adult NCFB patients in a single tertiary medical center. All patients were followed up for 36 months since study enrollment. Univariate and multivariate Cox proportional hazards models were generated to test the association between the potential clinical, imaging, microbiological and functional factors with the mortality risk in the study cohort. <b>Results:</b> A total of 401 NCFB patients (57±14 years, 57% men) were enrolled and followed up during the study period. The most common etiology types of the NCFB in the study patients were idiopathic (33%), post-TB (22%) and COPD related bronchiectasis (18%). A severe BSI score (≥9) was identified in 78% of the patients and pulmonary hypertension (PH) - in 35% of the cases. During the follow-up period 99 patients (25%) died. Multivariate Cox regression analysis identified an independent association with the risk of death of the following factors MRC dyspnea score (HR: 2.54; 95% CI: 1.83-3.5; p<0.0001); <i>Pseudomonas</i> colonization status (HR: 1.9; 95% CI: 1.19-3.0; p=0.006); age (HR: 1.03; 95% CI: 1.01-1.05; p= 0.001); HIV infection (HR: 8.31; 95% CI: 3.83-18.03; p<0.0001); ratio of the diameter of the main pulmonary arteria to the diameter of the ascending aorta on the HRCT (HR: 3.7; 95% CI: 1.09-12.83; p=0.03) and BMI (HR: 0.95; 95% CI: 0.92-0.99; p=0.02). <b>Conclusion:</b> Patients with imaging features of severe bronchiectasis has a significant risk of death, that being associated with more severe MRC score, <i>Pseudomonas</i> colonization, HIV infection, BMI and imaging signs of PH on HRCT." @default.
