目的了解肺炎支原体(MP)感染引起肺外各系统受累的临床特点。方法选取2005年1月1日～2007年12月31日住院的78例(男32例,女46例,平均年龄6.9岁)肺炎支原体感染的病人进行临床致病分析。结果肺外感染占同期肺炎支原体感染的33.1%,以循环系统、神经系统、血液系统、皮肤黏膜受累为主,分别占44.9%、19.2%、8.9%、10.3%。结论肺炎支原体感染以学龄期儿童多见,无明显性别差异,可出现多系统受累,预后良好。发病机理普遍认为与免疫因素相关。由于肺外支原体感染的肺外症状呈多样化,需引起重视,防止漏、误诊。
Objective To understand the clinical characteristics of Mycoplasma pneumoniae (MP) infection caused by extra-pulmonary system involvement. Methods A total of 78 patients (32 males, 46 females, mean age 6.9 years) with mycoplasma pneumoniae who were hospitalized from January 1, 2005 to December 31, 2007 were enrolled in this study. Results The extrapulmonary infection accounted for 33.1% of mycoplasma pneumoniae infection in the same period, mainly involving the circulatory system, nervous system, hematological system and mucocutaneous mucosa, accounting for 44.9%, 19.2%, 8.9% and 10.3% respectively. Conclusions Mycoplasma pneumoniae infection is more common in school-age children and there is no obvious gender difference. Multi-system involvement may occur and the prognosis is good. The pathogenesis is generally believed to be related to immune factors. Due to extrapulmonary mycoplasma infection of the extrapulmonary symptoms were diversified, need attention, to prevent leakage, misdiagnosis.
