目的:探讨肺炎支原体肺炎在我院2011年儿科患者中的分布情况及检测其抗体对临床诊断、治疗的价值。方法:采用被动凝集法检测1511例呼吸道感染患者血清肺炎支原体抗体。结果:1511例患儿MY-Igm阳性的有422例,占27.93%;其中主要症状的阳性率分别为:肺炎为44.31%;喉炎为5.45%;上感为9.95%;支气管肺炎为10.90%;气管炎为7.11%;咽炎为10.19%。在不同年龄组中,>1～5、>5～10岁的2个年龄组的阳性率高于0～1、>10～14岁2个年龄组。7～9月份阳性率高于其他月份。结论:肺炎支原体抗体Igm阳性率在呼吸道感染的患儿中占有较高的比例为27.93%;其中肺炎在阳性标本中所占比例最高为44.31%,其次是支气管肺炎和咽炎,分别为10.90%和10.19%;在阳性患儿中以>1～5岁的年龄组的阳性率最高为61.14%;在7～9月份发病率最高;实验室检测肺炎支原体抗体有助于早诊断、早治疗、指导临床合理用药、避免并发症的发生有重要意义。
Objective: To investigate the distribution of Mycoplasma pneumoniae pneumonia in pediatric patients in our hospital in 2011 and its value in clinical diagnosis and treatment. Methods: Serum Mycoplasma pneumoniae antibody was detected in 1511 patients with respiratory tract infection by passive agglutination. Results: Among the 1511 children, there were 422 cases with MY-Igm positive, accounting for 27.93%. The positive rates of major symptoms were: pneumonia was 44.31%, laryngitis was 5.45%, flu was 9.95%, bronchopneumonia was 10.90% ; Tracheitis was 7.11%; pharyngitis was 10.19%. In different age groups, the positive rates of> 1 ~ 5 and> 5 ~ 10 years old two age groups were higher than those of 0 ~ 1 and> 10 ~ 14 years old age groups. The positive rate from July to September was higher than other months. Conclusion: The positive rate of IgM in Mycoplasma pneumoniae is 27.93% of the total in children with respiratory tract infection. The highest proportion of pneumonia in positive samples is 44.31%, followed by bronchopneumonia and pharyngitis, which are 10.90% and 10.19%. In the positive children, the highest positive rate was 61.14% in the group of> 1 to 5 years old and the highest in July to September. The detection of Mycoplasma pneumoniae antibody in the laboratory could help early diagnosis, early treatment and guidance Clinical rational use of drugs to prevent the occurrence of complications of great significance.
