ABSTRACT
Objective:To investigate the etiological characteristics and changes of plastic bronchitis(PB)in children from 2010 to 2019 at Shenzhen Children′s Hospital, and provide reference basis for improving the understanding of PB etiology.Methods:The clinical data of children diagnosed with infectious-associated PB at Shenzhen Children′s Hospital from Jan 2010 to Dec 2019 were retrospectively analyzed, and the etiological characteristics and changes were summarized.Results:There were 94 cases of mycoplasma pneumoniae, 38 cases of influenza virus, 41 cases of adenovirus, 16 cases of mixed infection, 11 cases of bacteria, and 57 cases of unclear etiology in 266 infectious-associated PB children.The distribution of PB in each age group: 15 cases were infants, 63 cases were toddlers, 112 cases were preschoolers, and 76 cases were school-age children.Adenovirus was the main pathogen of PB in infants and toddlers(60.0%, 28.6%), and mycoplasma pneumoniae(34.8%, 60.5%) as well as influenza virus(13.4%, 22.4%) were the main pathogen in preschool and school-age children, with statistically significant difference( P<0.001). From 2010 to 2019, the annual positive rates of pathogens were 62.5%, 60.0%, 66.7%, 74.1%, 64.0%, 50.0%, 93.3%, 57.1%, 75.0%, and 84.7%, respectively.PB was caused by mycoplasma pneumoniae infection every year.From 2016 to 2019, PB caused by mycoplasma pneumoniae infection increased year by year, while PB caused by adenovirus infection increased every other year. Conclusion:Mycoplasma pneumoniae was the most common pathogen of PB, followed by adenoviruses and influenza viruses, while bacteria, fungi and other viruses were relatively rare.In the infant group, adenovirus infection was predominant, while in preschool and school-age children group, mycoplasma pneumoniae and influenza virus infection were predominant.
