Clinical characteristics and risk factors of pulmonary embolism with Mycoplasma pneumoniae pneumonia in children.

Pulmonary embolism is a rare but serious complication in Mycoplasma pneumoniae pneumonia patients, leading to serious sequelae and even death. We aim to retrospectively analyze the clinical features of Mycoplasma pneumoniae pneumonia with pulmonary consolidation in children and to explore the independent risk factors for progression to pulmonary embolism. Clinical data of 207 children with Mycoplasma pneumoniae pneumonia complicated with pulmonary consolidation were collected, and the patients were divided into the pulmonary embolism group (69 patients) and the control group (138 patients). Multivariate logistic regression was used to analyze the risk factors and the predictive efficacy was evaluated by receiver operating characteristic curve. Multivariate logistic regression analysis showed that fever days, D-dimer, immunoglobulin A, chest pain, extra-respiratory symptoms, plastic bronchitis and cutaneous mucosal system complications were the independent risk factors. Fever days ≥ 7.5, D-dimer ≥ 0.895 mg/L, immunoglobulin A ≥ 1.015 g/L, chest pain, extra-respiratory symptoms, plastic bronchitis and cutaneous mucous system complications significantly increased the risk of pulmonary embolism in children with Mycoplasma pneumoniae pneumonia complicated with pulmonary consolidation.
