ABSTRACT
Objective To analyze the prognosis of children with severe mycoplasma pneumonia (MPP) and its correlation with serum SAA, PCT and SF levels, so as to provide a basis for evaluating the prognosis of children with MPP. Methods A total of 273 children with MPP admitted to our hospital from January 2020 to December 2020 were divided into mild MPP children (n=187) and severe MPP children (n=86) according to the severity of their disease. According to the prognosis, children with severe MPP were divided into survival group (n=65) and death group (n=21). Serum SAA, PCT and SF levels were determined. Pearson correlation analysis was used to analyze the correlation between serum SAA, PCT and SF levels and APACHE ⅱ score. ROC curve was used to analyze the predictive value of serum SAA, PCT and SF levels for poor prognosis of children with severe MPP. Results The levels of serum SAA, PCT and SF and APACHE II score in children with severe MPP were significantly higher than those in children with mild MPP (P<0.05). Serum SAA, PCT and SF levels and APACHE II score in death group were significantly higher than those in survival group (P<0.05). Pearson correlation analysis showed that APACHE II score was positively correlated with serum SAA, PCT and SF levels (r =0.474,0.519,0.446,P<0.05). The AUC, sensitivity and specificity of combined ROC curve analysis to predict the prognosis of severe MPP were 0.871, 85.9% and 93.6% respectively, which were higher than those of SAA, PCT and SF alone. Conclusion SAA, PCT and SF are closely related to the prognosis of severe MPP, and can be used as potential markers to predict poor prognosis of severe MPP children.
ABSTRACT
Objective:To analyze the influences of azithromycinantibiotic combined glucocorticoids on the levels of erythrocyte sedimentation rate (ESR),serum lactate dehydrogenase (LDH) and inflammatory cytokines levels as well as the clinical effect of severe pneumonia mycoplasma.Methods:112 children with severe pneumonia mycoplasma who were treated in our hospital were selected and randomly divided into the control group and the observation group with 56 cases in each group.The patients in the control group were treated with azithromycinantibiotic,while the patients in the observation group were treated with glucocorticoid on the basis of the control group.Then the levels of ESR,LDH,isoenzyme MB (CK-MB),creatine kinase (CK),aspertate aminotransferase (AST),c-reactive protein (CRP),interleukin 6 (IL-6),tumor necrosis factor-o (TNF-α),CD4+ and CD8+,the clinical efficacy and adverse reactions between two groups were observed and compared before and after the treatment.Results:The effective rate in the observation group was higher than that of the control group,and the difference was statistically significant (P＜0.05).After treatment,the levels of ESR,LDH,CK-MB,CK,AST,CRP,IL-6,TNF-α and CD8+ in the two groups decreased,which were lower in the observation group than those of the control group (P＜0.05).After treatment,the levels of CD4+ in both groups increased,which was higher in the observation group than that of the control group (P＜0.05).The disappearance time of fever,cough relief,lung rale of observation group were shorter than those of the control group(P＜0.05).There was no statistically significant difference in the adverse reactions between the two groups (P＞0.05).Conclusion:Azithromycin combined with glucocorticoids was more effective than azithromycin alone in the treatment of severe mycoplasma pneumonia with high safety,which could obviously relieve the myocardial injury and inflammatory response,enhance the immune function.
