Clinical Characteristics and Predictive Factors Analysis of Mycoplasma Pneumoniae Pneumonia Complicated with Pleural Effusion in Children
Abstract
Mycoplasma pneumoniae pneumonia (MPP) is a prevalent cause of respiratory infections in children, sometimes leading to pleural effusion (PE). This study aimed to identify risk factors and clinical features associated with PE in pediatric MPP patients.
We conducted a retrospective case-control study involving 412 children with MPP and 82 with MPP+PE at the Third Affiliated Hospital of Wenzhou Medical University from January 2021 to January 2024. Demographic, clinical, and laboratory data were analyzed using multivariate logistic regression and receiver operating characteristic (ROC) curves.
Significant findings included a higher incidence of immunocompromised states in the MPP+PE group (18.29% vs. 8.98%). At admission, children with MPP+PE exhibited higher respiratory rates (29.94 vs. 29.16 breaths/min), lower oxygen saturation (82.33% vs. 83.14%), longer fever duration (5.75 vs. 4.83 days), elevated white blood cell counts (WBC) (11.64×10^9/L vs. 10.12×10^9/L), and increased erythrocyte sedimentation rates (ESR) (20.66 vs. 19.49 mm/h). Patients with PE also experienced longer antibiotic treatment (9.14±4.91 vs. 7.46±3.29 days) and extended hospital stays (13.58±4.18 vs. 12.37±3.52 days). Multivariate analysis identified several significant predictors of PE, and a joint prediction model achieved an area under the curve (AUC) of 0.842, sensitivity of 0.796, and specificity of 0.793.
These findings suggest that specific clinical and laboratory factors can help identify children at higher risk for PE, facilitating timely interventions.
