Abstract
Objective To explore the interleukin-4 (IL-4),interleukin-6 (IL-6),interferon-gamma (IFN-γ) levels in bronchoalveolar lavage fluid (BALF) of children with refractory mycoplasma pneumoniae pneumonia,and the features of bronchoscopy.Methods A total of 47 children with refractory mycoplasma pneumoniae pneumonia were selected as the observation group,28 children with bronchial foreign body in GAN zhengyan were chosen as controls during the same period.ELISA method was used to detect the IL-4,IL-6,IFN-γ levels in the BALF,and compared them in these two groups.The bronchoscope features of the observation group were observed.Results The IL-4,IL-6,IFN-γ levels in the BALF of children in the observation group were (8.3 ± 3.1) pg/mL,(62.3 ± 18.4) pg/mL,(76.5 ± 21.9) pg/mL,and they were significantly higher than those of the controls (3.1 ± 1.2) pg/m L,(30.0 ± 1.5) pg/m L,(31.3 ± 24.9) pg/mL (P ＜0.05,respectively).In the observation group,the bronchial mucosa congestion and edema were observed in all patients,there were variable amounts of mucus secretions.There were other changes include:microtubule reductus (68.1％),bronchial mucosal follicle-like hyperplasia (38.3％),mucosal erosions (8.5％),airway inflammatory stenosis,mucus plug blocking (59.6％),granulation proliferation (14.9％),bronchial obliteration (4.3％) Conclusions The IL-4,IL-6,IFN-γ levels in the BALF of children with RMPP significantly increased.This indicates a significant local inflammatory response in children with RMPP.Mycoplasma pneumoniae pneumonia (MPP) has certain features of bronchoscope,these features are helpful to the diagnosis and treatment of MPP.关键词
