Clinical features of influenza with plastic bronchitis in children
Objective To study the clinical features of influenza with plastic bronchitis (PB) in children, and to improve the awareness of the diagnosis and treatment of PB caused by influenza virus. Methods A retrospective analysis was performed for the clinical data of 70 children with lower respiratory influenza virus infection from October 2018 to October 2019. According to the presence or absence of PB, they were divided into an influenza+PB group with 12 children and a non-PB influenza group with 58 children. Related clinical data were collected for the retrospective analysis, including general information, clinical manifestations, laboratory examination, imaging findings, treatment, and prognosis. Results In the influenza+PB group, most children experienced disease onset at the age of 1-5 years, with the peak months of January, February, July, and September. Major clinical manifestations in the influenza+PB group included fever, cough, and shortness of breath. The influenza+PB group had significantly higher incidence rates of shortness of breath and allergic diseases such as asthma than the non-PB influenza group (P < 0.05). Of the 12 children in the influenza+PB group, 7(58%) had influenza A virus infection and 5 (42%) had influenza B virus infection, among whom 1 had nephrotic syndrome. For the children in the influenza+PB group, major imaging findings included pulmonary consolidation with atelectasis, high-density infiltration, pleural effusion, and mediastinal emphysema. Compared with the non-PB influenza group, the influenza+PB group had a significantly higher proportion of children who were admitted to the pediatric intensive care unit (P < 0.05). Bronchoscopic lavage was performed within 1 week after admission, and all children were improved and discharged after anti-infective therapy and symptomatic/supportive treatment. Conclusions Influenza with PB tends to have acute onset and rapid progression, and it is important to perform bronchoscopy as early as possible. The possibility of PB should be considered when the presence of shortness of breath, allergic diseases such as asthma or nephrotic syndrome in children with influenza.
