Abstract:
Objective:To investigate the relationship between peripheral blood amyloid protein A(SAA),C-reactive protein(CRP)/prealbumin(PA),vascular endothelial growth factor(VEGF)and the severity,pulmonary function,and prognosis of children with Mycoplasma pneumoniae pneumonia(MPP).Methods:106 children with MPP who were admitted to Huichang County Maternal and Child Health Hospital of Ganzhou from February 2023 to August 2024 were selected as the study subjects(MPP group),they were divided into good prognosis group(n=77)and poor prognosis group(n=29)according to the 28 days prognosis,they were divided into mild group(n=61)and severe group(n=45)according to the disease severity.Another 90 healthy children who underwent physical examinations during the same period were selected as the control group.The peripheral blood SAA,CRP/PA,VEGF,and pulmonary function indicators between the control group and MPP group were compared,and the peripheral blood SAA,CRP/PA,and VEGF levels between the mild group and severe group were compared,Pearson and Spearman correlation analysis was used to investigate the correlation between peripheral blood SAA,CRP/PA,VEGF and pulmonary function indicators and disease severity in children with MPP.The levels of peripheral blood SAA,CRP/PA,and VEGF between poor prognosis group and good prognosis group were compared.Receiver operating characteristic(ROC)curve was used to analyze the value of peripheral blood SAA,CRP/PA,VEGF detection alone and in combination for evaluating the 28 days prognosis in children with MPP.Results:The peripheral blood SAA,CRP/PA,and VEGF levels in the MPP group were higher than those in the control group,while the forced expiratory volume in one second(FEV1),peak expiratory flow(PEF),and forced vital capacity(FVC)were lower than those in the control group(P＜0.05).Peripheral blood SAA,CRP/PA,and VEGF levels in the severe group were higher than those in the mild group(P＜0.05).Peripheral blood SAA,CRP/PA,VEGF were negatively correlated with FEV1,PEF,FVC,but positively correlated with the severity of the disease(P＜0.05).Peripheral blood SAA,CRP/PA,and VEGF in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).The area under the curve(AUC)values of peripheral blood SAA,CRP/PA,and VEGF for evaluating the 28 days prognosis of MPP patients were 0.514,0.562,and 0.585,respectively,the AUC of 28 days prognosis evaluation in children with MPP by combined detection of peripheral blood SAA,CRP/PA,and VEGF was 0.725,significantly higher than that of individual detection.Conclusion:Abnormal elevation of peripheral blood SAA,CRP/PA,and VEGF levels is involved in the progression of MPP,the injury of pulmonary function,and poor prognosis.combined detection of peripheral blood SAA,CRP/PA,and VEGF levels can effectively evaluate the short-term prognosis of MPP patients.
