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.
