Efficacy of fiberoptic bronchoscopy and bronchoalveolar lavage in childhood‐onset, complicated plastic bronchitis

Background Plastic bronchitis (PB) is a rare, variable, and potentially fatal disease. This study aimed to assess the efficacy of fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) in treating children with PB. Methods In total, 15 children with PB, between 2012 and 2020, were enrolled i...

Zusammenfassung:Background Plastic bronchitis (PB) is a rare, variable, and potentially fatal disease. This study aimed to assess the efficacy of fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) in treating children with PB. Methods In total, 15 children with PB, between 2012 and 2020, were enrolled in our study. Within 12 hours of admission, FOB and BAL were performed and reviewed under local anesthesia and sedation. Before and after FOB, clinical findings and chest imaging were evaluated. Results Regarding the onset of symptoms before FOB, all cases had prominent cough for 7.00 ± 4.55 days, and 14 had persistent high fever. In total, 13 cases had complete obstruction from bronchial casts, consistent with consolidated lesions; 2 had partial airway obstruction. Within 3 days, complete resolution was revealed in nine cases. Overall, six cases underwent repeated FOB (range, 2‐3 times) for persistent atelectasis and airway obstruction. Except for two cases with type 2 PB, cast histology confirmed type 1 PB for all cases. Only eight children had minor intra‐ and post‐procedure complications. Reverse transcription‐polymerase chain reaction for Mycoplasma pneumoniae in sputum and BAL samples were positive in 13 cases. Next‐generation sequencing of the BAL samples was positive for adenovirus and Human parainfluenza virus in one case, respectively. During 1 month to 7 years of follow‐up, no patient developed PB recurrence, asthmatic attacks, or chronic cough. Conclusions Early FOB and BAL were effective in alleviating clinical findings, atelectasis, and airway obstruction. Serial FOB could be performed in patients with recurrent symptoms.
