肺炎支原体(MP)感染有0.1%侵犯中枢神经系统,但在住院病人中,MP 感染的中枢神经系统的患病率可达7%。赫尔辛基大学儿童医院于1968年1月～1987年12月间收治脑炎462例,经血清 MP 抗体检测,41例符合 MP 感染诊断条件,即双份血清滴度≥4倍或血清滴度>64或脑脊液 MP 抗体阳性,而诊断为肺炎支原体脑炎。内女性22例、男性19例,年龄0.8～14.6岁,平均6.7岁。1975年为发病高峰,月份差异不显著。
Mycoplasma pneumonia (MP) infection affects 0.1% of the central nervous system, but the prevalence of MP-infected central nervous system is 7% in hospitalized patients. 462 cases of encephalitis were admitted to the Children’s Hospital of Helsinki University from January 1968 to December 1987. Serum MP antibody was detected in 41 cases, which met the diagnostic criteria of MP infection, ie double serum titer≥4 times or serum titer> 64 Or cerebrospinal fluid MP antibody positive, and diagnosed as Mycoplasma pneumoniae encephalitis. There were 22 female and 19 male patients, aged from 0.8 to 14.6 years old, with an average of 6.7 years. The peak incidence in 1975, the month difference was not significant.
