Objective: To explore the relationship between the platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR) and the severity of the disease in children with mycoplasma pneumoniae pneumonia (MPP). Method: Fifty children with common MPP and fifty children with severe MPP who were treated at Quanzhou Women's and Children's Hospital from January 2023 to June 2024 were selected as the study objects and they were set as the common group and the severe group respectively. The general data, PLR, NLR, MLR, C-reactive protein (CRP), D-dimer (D-D), lactate dehydrogenase (LDH) and other indicators of the two groups were compared. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curve analysis were used to analyze the correlations between PLR, NLR, MLR and the severity of the disease in children with MPP, as well as their predictive value. Result: There was no statistically significant difference in gender, the proportion of fever peak ≥39℃, fever duration, D-D, and LDH levels between the two groups (P>0.05). The age, proportion of fever, blood oxygen saturation and MLR in the severe group were all lower than those in the common group, while the proportions of shortness of breath and multi-lobe invasion, PLR, NLR and CRP were all higher than those in the common group, and the differences were statistically significant (P<0.05). Multivariate logistic regression analysis indicated that PLR, NLR, and MLR were independent influencing factors for the severity of the disease in children with MPP, and the difference was statistically significant (P<0.05). ROC curve analysis showed that the areas under the curves of PLR, NLR, and MLR for predicting the severity of MPP in children were 0.720, 0.869, and 0.713, respectively (P<0.05). Conclusion: PLR, NLR, and MLR are independent influencing factors for the severity of the disease in children with MPP, and they also have high predictive value for the severity of the disease.
