摘要肺炎支原体是我国儿童社区获得性肺炎主要的病原体之一，虽然大部分肺炎支原体肺炎患儿预后良好，但仍有少数患儿可进展为难治性肺炎支原体肺炎。相较于普通型肺炎支原体肺炎，难治性肺炎支原体肺炎患儿的临床症状及肺部影像学表现更重，发热和治疗时间更长且更容易出现肺外并发症。为了能更好地早期识别和治疗难治性肺炎支原体肺炎，已有学者开展了通过生物标志物、影像学表现及列线图等方法早期预测难治性肺炎支原体肺炎的研究。该文对近年来相关研究进行综述，为早期预测难治性肺炎支原体肺炎提供借鉴。

abstractsMycoplasma pneumoniae is one of the main pathogen of community-acquired pneumonia in children in China. Although most children with Mycoplasma pneumoniae pneumonia have a good prognosis，a small number of children can progress to refractory Mycoplasma pneumoniae pneumonia. Compared with general mycoplasma pneumoniae pneumonia，the clinical symptoms and lung imaging findings of refractory Mycoplasma pneumoniae pneumonia are more serious. Fever and treatment time are longer and extrapulmonary complications are more likely to occur. In order to better identify and treat refractory Mycoplasma pneumoniae pneumonia at an early stage，some scholars have carried out studies on early prediction of refractory Mycoplasma pneumoniae pneumonia by using biomarkers，imaging findings and nomogram. This paper reviews relevant studies in recent years，to provide reference for early prediction of refractory Mycoplasma pneumoniae pneumonia.
