Abstract:
Objective:To analyze the clinical features of bronchiectasis in children after severe adenovirus pneumonia and to provide clinical clues for the early diagnosis of bronchiectasis in children after severe adenovirus pneumonia.Methods:A retrospective study was made to analyze the clinical data of 26 children with bronchiectasis after severe adenovirus pneumonia treated in Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from May 2016 to May 2021.Results:A total of 26 cases were reported, including 18 males and 8 females.The median onset age of severe adenovirus pneumonia was 23.0 (15.0, 48.0) months.A total of 23 cases suffered concurrent infections, and bacterial co-infection was the most common (16 cases). High resolution computed tomography (HRCT) showed multiple lobar solids in the lung with/without pleural effusion.During the acute phase, most of the cases were treated with intravenous immunoglobulin (21 cases), mechanical ventilation (20 cases), and systemic glucocorticoids (19 cases). The median age at diagnosis of bronchiectasis was 29.5 (21.0, 56.8) months, and the median time that the patients took to develop into acute adenovirus pneumonia was 6.0 (3.3, 13.0) months.Six cases suffered bronchiectasis alone, and 20 cases had bronchiectasis combined with post-infectious bronchiolitis obliterans (PIBO). Of these 20 cases, 3 cases developed bronchiectasis and PIBO simultaneously, and the remaining 17 cases developed bronchiectasis after PIBO.In the included 26 cases, diffuse bronchiectasis predominated (24 cases), most frequently involving the left lower lobes (21 cases) and right lower lobes (21 cases). Cylindrical bronchiectasis was the most common type (23 cases). All the patients had recurrent cough and wheezing during follow-up, and only 3 cases coughed up pus sputum without hemoptysis.All children had acute exacerbations, which were mostly caused by bacteria (21 cases). Nineteen cases combined with PIBO and 1 case with only bronchiectasis were rehospitalized.There was no cases of surgical resection or death.Conclusions:Bronchiectasis after severe adenovirus pneumonia mostly occurs in patients with or without PIBO.Multiple lobe involvement and co-infection may be a risk factor for PIBO patients to develop bronchiectasis.The clinical manifestations are mostly recurrent cough and wheezing, while sputum and hemoptysis are less common.Pediatricians should promptly perform chest HRCT for early diagnosis of the disease.
