肺炎支原体感染的流行病学研究

目的: 研究小儿肺炎支原体(Mycoplasma pneumoniae,MP)感染的流行特点,与年龄、季节、性别的关系以及MP感染后的首发症状。方法: 对1999~2004年门诊和住院14岁以下部分患儿的血清,用被动凝聚法检测MP特异IgM抗体。结果: MP-Ab阳性率有一定规律;一年四季间差异有显著性(P<0.01);男女性别间差异有显著性(P<0.005);多见于学龄前儿童(32.24%)和学龄期儿童(40.63%);近年来,MP感染引起的肺外症状有明显增加趋势。结论: MP感染的流行与年龄、季节、性别有密切的关系,MP感染引起的肺外损伤有增加趋势。

Epidemiology study of Mycoplasma pneumoniae infection

Objective:To study the prevailing characteristics of the infantile Mycoplasma pneumoniae infection,its relations with the age,season,sex and the initial symptoms after MP infection.Methods:The MP-Ab in the serum of some children under the age of 14 who were treated in our hospital from Jan.1999 to Dec.2004 was measure by the method of passive particle agglutination.Results:The positive rate of!MP-Ab had certain laws:there was significant difference between the four seasons(P<0.01);the difference was significant between the male and the female(P<0.005);It was commonly seen in the preschool children(32.24%) and the school children(40.63%).The symptoms outside the lung caused by MP infection tended to increase.Conclusions:The MP infection is closely related with the age,season and sex.The lesion outside the lung caused by MP infection has the tendency to increase in recent years.
