Diagnostic and prognostic value of NLR and PLR detection in children with mycoplasma pneumonia infection
Objective To investigate the diagnostic and prognostic value of neutrophil/lymphocyte ratio(NLR)and platelet/lymphocyte ratio(PLR)in children with mycoplasma pneumonia(MP)infection.Methods The retrospective analysis was adopted.One hundred children patients with MP-IgM positive from January to June 2023 served as the case group,and other 100 healthy children during the same period were ex-tracted as the control group;the results of the first re-examination in the case group served as the standard,the children patients in the case group were divided into the unrecovered group(MP-IgM positive)and the re-covered group(MP-IgM negative);the levels of NLR and PLR were compared among the groups,and the lo-gistic regression model was established,then the receiver operating characteristic(ROC)curve was used to an-alyze the diagnostic value of the two.Results The levels of NLR and PLR in the case group were significantly higher than those in the control group(P＜0.05);the areas under the curve(AUC)of single detection and combined detection of NLR and PLR in the diagnosis of the children patients with MP infection were 0.749,0.701 and 0.758 respectively.AUC of the combined detection was maximal,the corresponding sensitivity was 83.00％and the specificity was 61.00％(P＜0.001).The levels of NLR and PLR in the unrecovered group were also significantly increased compared with those in the recovered group(P＜0.05).Conclusion NLR and PLR are closely correlated to MP infection,and their combined detection has the higher sensitivity for MP in-fection and the both also have a certain prompt effect on the prognosis in the children patients.
