Abstract:
Objective To explore the value of serum amyloid A(SAA)/C-reactive protein(CRP),lactate dehydrogenase(LDH),and Gal-9(Gal-9)levels in the condition and prognosis of children with refractory my-coplasma pneumoniae pneumonia(RMPP).Methods A prospective study was conducted on totally 200 chil-dren with mycoplasma pneumoniae pneumonia(MPP)who visited the hospital from September 2021 to De-cember 2023.They were divided into general mycoplasma pneumoniae pneumonia(GMPP)group(n=132)and RMPP group(n=68)based on their condition,and they were divided into effective group(n=47)and in-effective group(n=21)based on the outcome of RMPP.General line data and laboratory data of pediatric pa-tients were collected,enzyme-linked immunosorbent assay was used to detect SAA,CRP,LDH,Gal-9,and SAA/CRP was calculated.Baseline data and laboratory indicators of children with different MPP conditions and RMPP children with different prognosis outcomes were compared.Multivariate Logistic regression analy-sis was used to analyze the independent influencing factors on clinical efficacy in children with RMPP.The cor-relation between SAA/CRP,LDH,and Gal-9 was analyzed.Receiver operating characteristic(ROC)curve a-nalysis was analyzed to predict the clinical efficacy of SAA/CRP,LDH,and Gal-9 in children with RMPP.Re-sults The levels of SAA/CRP,LDH,and Gal-9 in the RMPP group were higher than those in the GMPP group(P＜0.05).The levels of SAA/CRP,LDH,and Gal-9 in the ineffective group were higher than those in the effective group(P＜0.05).Logistic analysis showed that SAA/CRP,LDH,and Gal-9 were all independent influencing factors for clinical efficacy in children with RMPP(P＜0.05).Pearson correlation analysis showed that SAA/CRP,LDH,and Gal-9 were positively correlated pairwise(r=0.427,0.431,0.378).The ROC curve showed that the area under the curve(AUC)of the combination of SAA/CRP,LDH,and Gal-9 in pre-dicting the clinical efficacy of RMPP was 0.816(95％CI:0.775-0.913),which was higher than those of sin-gle serum marker diagnosis(P＜0.05).Conclusion The serum levels of SAA/CRP,LDH,and Gal-9 in chil-dren with RMPP could be used for disease condition and prognosis evaluation,and there is a close correlation between the above indicators.The combined prediction has a relatively high efficacy in predicting the prognosis of children with RMPP.
