儿童肺炎支原体感染肺外表现的研究进展

Progress of extrapulmonary manifestations of Mycoplasma pneumoniae infection in children

肺炎支原体（mycoplasma pneumoniae，MP）是介于细菌与病毒之间的一类无细胞壁的原核生物，是儿童呼吸道感染的常见病原，但也可无肺部感染的任何症状，却引起广泛的肺外临床表现。MP感染肺外表现可涉及心血管、神经、消化、血液以及皮肤黏膜等多个系统，临床表现多样。为提高临床医生对MP感染肺外表现的进一步认识，该文就MP感染肺外表现的诊治进展作一综述。

Mycoplasma pneumoniae （MP）, a type of prokaryotes without cell wall between bacteria and viruses, is one of the most common agents of respiratory tract infection in children. However,it can also cause a wide range of extrapulmonary manifestations in the absence of any pulmonary symptoms. MP infection may present a variety of clinical manifestations, involving cardiovascular, neurological, digestive, hematological, mucocutaneous and other symptoms. This article reviews the progress of extrapulmonary manifestations of MP infection to improve the comprehension for diagnosis.
