Application of Clinical Indicators in the Early Prediction of Refractory <i>Mycoplasma pneumoniae</i> Pneumonia in Children: A Retrospective Study.
Elevated LDH, IL-6, and D-dimer levels are strong predictors of refractory Mycoplasma pneumoniae pneumonia in children, aiding early risk assessment.

this study against the rest of the zenagamtide corpusSummary and findings
This retrospective study examined 223 children with Mycoplasma pneumoniae pneumonia to identify predictive factors for refractory cases. Elevated levels of LDH, IL-6, and D-dimer were significant predictors of refractory Mycoplasma pneumoniae pneumonia. A predictive nomogram was developed to improve early clinical prediction of refractory cases.
Abstract
This study aims to compare the clinical characteristics of children with general <i>Mycoplasma pneumoniae</i> pneumonia (GMPP) and refractory <i>Mycoplasma pneumoniae</i> pneumonia (RMPP), identify predictive factors for RMPP, and construct a predictive nomogram for early clinical prediction of RMPP. This retrospective study included 223 children with <i>Mycoplasma pneumoniae</i> pneumonia admitted to Lishui District People's Hospital in Nanjing from June 2023 to February 2024. Children were divided into GMPP (171 cases) and RMPP (52 cases) based on treatment response. Baseline characteristics, laboratory findings, and imaging results were compared between groups. Multivariate logistic regression and receiver operating characteristic curve analysis were used to identify and evaluate predictive factors for RMPP. The RMPP group had higher incidence of dyspnea, lung consolidation, atelectasis, and pleural effusion, and longer hospital stays. Laboratory tests showed elevated C-reactive protein, interleukin-6 (IL-6), D-dimer, and lactate dehydrogenase (LDH) levels in RMPP compared with GMPP. Multivariate analysis identified LDH, IL-6, and D-dimer as significant predictive factors for RMPP. The combined model's area under the curve was 0.946, indicating high prediction efficacy. Elevated levels of LDH, IL-6, and D-dimer are associated with RMPP. The predictive nomogram based on these markers improves RMPP risk assessment, providing a scientific basis for early recognition and personalized treatment.
Background
Mycoplasma pneumoniae pneumonia is a common respiratory infection in children, but some cases become refractory to standard treatment. Identifying early predictive factors for refractory Mycoplasma pneumoniae pneumonia (RMPP) can improve patient management and outcomes. This study aims to fill the gap in early prediction by constructing a nomogram based on clinical indicators.
Methods
This retrospective study analyzed 223 children diagnosed with Mycoplasma pneumoniae pneumonia at Lishui District People's Hospital from June 2023 to February 2024. Patients were divided into general (171 cases) and refractory (52 cases) groups based on treatment response. Baseline characteristics, laboratory findings, and imaging results were compared. Multivariate logistic regression and ROC curve analysis were used to identify predictive factors.
Results
The primary endpoint was the identification of predictive factors for RMPP, with LDH, IL-6, and D-dimer levels being significant. The RMPP group showed higher rates of dyspnea, lung consolidation, atelectasis, and pleural effusion, and longer hospital stays. The predictive model's AUC was 0.946, indicating high efficacy.
Interpretation
The study's findings align with existing literature on inflammatory markers in pneumonia but provide specific predictive factors for RMPP. While the statistical significance is strong, the clinical utility of the nomogram needs further validation in diverse populations. Confounding factors include the retrospective design and single-site data collection.
