Destroyed lung contributes to the recurrence of hemoptysis after bronchial artery embolization in patients with post-tuberculosis bronchiectasis
Abstract
Background: Bronchiectasis has high rates of hemoptysis and recurrent hemoptysis, which is inconsistent among various etiologies. Idiopathic bronchiectasis and post-tuberculous bronchiectasis are two important etiologies in China, but the differences in clinical features and risk factors of recurrent hemoptysis have not been elucidated. Methods: Patients hospitalized for idiopathic bronchiectasis or post-tuberculosis bronchiectasis were included. Patients were followed up for at least 24 months post-BAE. Demographic characteristics and clinical data were collected and analyzed between idiopathic bronchiectasis and post-tuberculosis bronchiectasis. Based on the outcomes of recurrent severe hemoptysis in patients with post-tuberculosis bronchiectasis, Cox regression models were used to identify risk factors for recurrence. Results: Among 417 patients including 352 idiopathic bronchiectasis and 65 post-tuberculous bronchiectasis, 209 (50.1%) were females. Compared with the idiopathic group, the proportion of patients with female (54.5% vs. 26.2%, p < 0.001), with sputum (79.5% vs. 36.9%, p < 0.001), isolation of Pseudomonas aeruginosa (28.7% vs. 7.7%, p < 0.001), and the number of bronchiectatic lobes≥ 3(98.3% vs 50.8%, p < 0.001) were lower, and the proportion of destroyed lung (4.5% vs. 26.6%, p < 0.001) and recurrence of severe hemoptysis (22.4% vs. 41.5%, p = 0.001) were higher in the post-tuberculous group. Among patients with post-tuberculosis bronchiectasis, destroyed lung [HR: 3.2(1.1,9.1), p = 0.026] and abnormal esophageal proper artery [HR: 2.8(1.1,7.0), p = 0.032] were two independent risk factors for the recurrence of hemoptysis. Conclusions: The recurrence rate of severe hemoptysis in patients with post-tuberculous bronchiectasis receiving BAE is high, and the proper esophageal artery should be actively evaluated and standardized treatment should be given.
