目的分析本院呼吸道感染患儿非典型病原体现状和临床特征,为临床诊治提供依据。方法收集本院呼吸道感染的儿童患者3 270例,检测9种非典型呼吸道病原体的Ig M抗体,比较其阳性率与性别、年龄及季节的相关性。结果非典型呼吸道病原体的总阳性检出率为46.09%,以MP检出率最高;男童阳性率为45.45%,女童为46.63%,两者差异无统计学意义(P>0.05);冬季病原体检出率最高,秋季检出率最低,春季和夏季差异无统计学意义(P>0.05),与其他2季差异有统计学意义(P<0.05)。0岁~1岁、~3岁、~6岁、~9岁和~14岁各年龄组间除了~3岁和~6岁组,差异有统计学意义(P<0.05)。结论 MP是引起呼吸道感染最重要的非典型病原体,与性别无关,与年龄和季节有关,3岁~6岁儿童是易感人群。
Objective To analyze the status and clinical features of atypical pathogens in children with respiratory tract infection in our hospital and provide the basis for clinical diagnosis and treatment. Methods A total of 3 270 children with respiratory tract infections in our hospital were collected for IgM antibody detection of nine atypical respiratory pathogens. The positive rates were compared with sex, age and season. Results The positive rate of MP was 46.09% and the highest was detected by MP. The positive rate was 45.45% for boys and 46.63% for girls, with no significant difference between the two groups (P> 0.05) The detection rate was the highest, the lowest was in autumn, there was no significant difference between spring and summer (P> 0.05), and the difference was statistically significant with other two seasons (P <0.05). The difference was statistically significant (P <0.05) except 0 to 1 year old, ~ 3 years old, ~ 6 years old, ~ 9 years old and ~ 14 years old except for ~ 3 years and ~ 6 years old groups. Conclusion MP is the most important atypical pneumonia causing respiratory tract infection and has nothing to do with sex, age and season, and children aged 3 to 6 years are susceptible.
