Abstract:
Objective:To compare the clinical characteristics of severe Mycoplasma pneumoniae pneumonia（SMPP）with bronchiolitis and consolidation to raise awareness.Methods:Retrospective analysis was conducted on children hospitalized at the first affiliated hospital of Xiamen University diagnosed with（SMPP）from February 2023 to January 2024.The children were divided into bronchiolitis group and large consolidation group based on their high-resolution CT imaging findings.Data on basic information，clinical features，auxiliary examination results，and bronchoscopy findings were analyzed.Results:This study included 415 pediatric patients，including 203 with bronchiolitis and 212 with large consolidation.The proportion of males，atopy rate，and first-degree relative atopy rate in the bronchiolitis group were higher，and the age of the bronchiolitis group was younger（ P<0.05）.The fever peak，incidence of fever，and low breath sound in the bronchiolitis group were lower，and the incidence of hypoxemia，wheezing，shortness of breath，inspiratory tri-concave signs，moist rales were higher than those in the consolidation group（ P<0.05）.The white blood cell counts，platelet counts，and lactate dehydrogenase were higher and the percentage of neutrophils，C-reactive protein，ferritin，D-dimer，and fibrinogen degradation products were lower in the bronchiolitis group than those in the consolidation group（ P<0.05）.The rate of 2 or more bronchoscopy procedures，and the proportion of longitudinal plica，mucus plug，and plastic in the consolidation group were higher than those in the bronchiolitis group（ P<0.05）.After three months of follow-up，there were 8 cases of bronchiolitis obliterans，including 7 cases in the bronchiolitis group and 1 case in the large consolidation group. Conclusion:If atopy，wheezing，and dyspnea are present in young children and preschool children with confirmed SMPP，they should be closely monitored for signs of bronchiolitis SMPP.Children with significant consolidation on imaging should have the possibility of various intrapulmonary and extrapulmonary problems taken into account.Appropriate treatment options should be implemented during the acute phase based on the imaging findings.
