Risk factors of severe Mycoplasma pneumoniae pneumonia in children with macrolide-resistant Mycoplasma pneumoniae pneumonia and the construction of prediction model
Objective To explore potential predictors of macrolide-resistant Mycoplasma pneumoniae pneumonia(MRMP)to severe Mycoplasma pneumoniae pneumonia(SMPP)in early stage.Methods A retrospective analysis was conducted on 117 cases of MRMP that were hospitalized in the First People's Hospital of Huzhou between January 2023 and January 2024.The children were divided into severe group and mild group based on the severity of their disease.A comparison of the clinical characteristics between two groups was conducted,along with an analysis of the risk factors contributing to the occurrence of SMPP.Results Among 117 children with MRMP,there were 63 in severe group and 54 in mild group.The duration of fever,cough,white blood cell count,C-reactive protein(CRP),and lactate dehydrogenase(LDH)in severe group were all higher than those in mild group(P＜0.05).Logistic regression analysis showed that the duration of fever,CRP,and LDH were independent risk factors for the development of SMPP from MRMP.Area under the curve of the three combined tests was 0.963(95％CI:0.935-0.991,P＜0.001).Conclusion The probability of MRMP developing into SMPP can be predicted based on the duration of fever,CRP,and LDH levels at the first visit of the patient,thereby achieving early diagnosis and treatment.
