Abstract

Background: Post-infectious bronchiolitis obliterans (PIBO) is a rare chronic obstructive pulmonary disease that occurs after a respiratory infection. Its diagnosis is generally based on clinical history, respiratory symptoms, and computed tomography (CT) findings.

Purpose: Here we evaluated the frequency of exacerbations, clinical progress, and inhaled corticosteroid (ICS) usage in children diagnosed with PIBO with or without comorbid bronchopulmonary dysplasia (BPD).

Methods: This retrospective observational study was conducted in Rouen, France. The inclusion criteria were as follows: child diagnosed with PIBO (history of respiratory infection, airway obstruction with no or poor response to bronchodilation treatment, and/or mosaic pattern or trapping on chest high-resolution CT (HRCT) in 2009-2024 treated with intravenous corticosteroid pulses.

Results: Fifty-seven patients were included: 13 (23%) with BPD and 44 (77%) without BPD. The mean age at diagnosis was 7 ± 3.6 months, with no significant intergroup difference. We observed a significant reduction in exacerbations following corticosteroid pulse treatment as soon as 6 months (p<0.001), with persistent effects observed up to 24 months (p=0.02). We also noted a reduced daily ICS dose starting at 12 months (p=0.03). Respiratory syncytial virus is the most commonly identified causative virus, followed by rhinoviruses and adenoviruses. The viral co-detection rates were 18% and 61% in the BPD and non-BPD groups, respectively.

Conclusion: In our cohort, intravenous corticosteroid pulse treatment effectively treated PIBO, with a rapid and long-lasting reduction in exacerbations and ICS requirements. BPD was a significant comorbidity of PIBO.

小儿感染后闭塞性细支气管炎伴与不伴支气管肺发育不良的临床病程
背景:传染性后闭塞性细支气管炎(PIBO)是一种罕见的慢性阻塞性肺疾病,发生在呼吸道感染后。其诊断通常基于临床病史、呼吸道症状和计算机断层扫描(CT)结果。目的:在这里,我们评估了PIBO患儿伴或不伴支气管肺发育不良(BPD)的发作频率、临床进展和吸入皮质类固醇(ICS)的使用情况。方法:这项回顾性观察性研究在法国鲁昂进行。纳入标准如下:2009-2024年经静脉皮质类固醇脉冲治疗的PIBO患儿(呼吸道感染史,气道阻塞,支气管扩张治疗无反应或反应差,和/或胸部高分辨率CT (HRCT)上的马赛克图案或陷波)。结果:纳入57例患者:13例(23%)有BPD, 44例(77%)无BPD。平均诊断年龄为7±3.6个月,组间差异无统计学意义。我们观察到皮质类固醇脉冲治疗后6个月的急性发作显著减少(结论:在我们的队列中,静脉注射皮质类固醇脉冲治疗有效地治疗了PIBO,急性发作和ICS要求迅速而持久地减少。BPD是PIBO的重要合并症。
