目的:研究0~14岁儿童肺炎支原体肺炎(MMP)合并胸腔积液(PE)的临床特点及危险因素,为临床诊治提供参考依据。方法:回顾性分析回顾性分析2021年6月至2024年6月我院儿科住院的社区获得性肺炎患儿的临床资料,共收取772例肺炎患儿,其中MMP患儿695例、MPP合并PE患儿77例,收集患儿的各项资料,包括临床特征及实验室检查资料,分析临床特点及危险因素。结果:1) 秋冬季是MMP合并PE的好发季节,MMP合并PE患儿年龄、热峰均高于MPP患儿,且热程,阿奇霉素治疗时间明显延长(P Objective: To investigate the clinical characteristics and risk factors of Mycoplasma pneumoniae pneumonia (MMP) complicated with pleural effusion (PE) in children aged 0~14 years, and provide reference for clinical diagnosis and treatment. Method: A retrospective analysis was conducted on the clinical data of community-acquired pneumonia patients admitted to our pediatric department from June 2021 to June 2024. A total of 772 pneumonia patients were collected, including 695 children with MMP and 77 children with MPP and PE. Various data, including clinical characteristics and laboratory examination data, were collected to analyze the clinical features and risk factors of the patients. Result: 1) Autumn and winter are the most common seasons for MMP combined with PE. Children with MMP combined with PE have higher age and fever peak than those with MPP, and the fever course and azithromycin treatment time are significantly prolonged (P < 0.05). 2) Compared with the MPP group, the MMP combined with PE group showed an increase in neutrophil percentage (NE%), C-reactive protein (CRP), procalcitonin (PCT), and lactate dehydrogenase (LDH) levels, while white blood cell (WBC) and lymphocyte percentage (LYM%) levels decreased, with statistical significance (P < 0.05). 3) Logistic regression analysis showed that treatment time with azithromycin, serum CRP, and LDH levels were independent risk factors for MMP combined with PE (P < 0.05)
