1482例呼吸道感染患者肺炎支原体感染情况分析

目的了解本地区肺炎支原体感染状况,为临床提供诊疗依据。方法用间接凝集法检测1482例患者血清中肺炎支原体特异性抗体IgM,滴度≥1∶80为阳性,≤1∶40为阴性。结果1482例患者中234例呈Mp-IgM阳性,阳性率为15.79%,效价最高达1∶1280,检出抗体最小年龄为3月,最大83岁。不同性别MP抗体检出率无显著性差异,不同年龄、不同季节MP抗体检出率有非常显著性差异,p<0.01。结论肺炎支原体四季均能引起呼吸道感染,以冬、春季尤甚,6~14岁儿童发病率尤高,对呼吸道感染者应加强Mp-IgM的检测,及时提供诊治依据,避免滥用抗生素。间接凝集法测Mp-IgM操作简单快速,适合临床使用。

THE ANALYSIS ABOUT MYCOPLASMA PNEUMONIA INFECTION IN 1482 RESPIRATORY INFECTION PATIENTS IN FOSHAN

Objective To find out the situation about the Mycoplasma pneumonia infection in this area and provide the diagnosis and treatment proofs for clinic. Method Detecting the Mycoplasma pneumonia distinctive antibody IgM in 1482 respiratory infection patients' serum with the indirect agglutination test. The consistence≥1∶80 is positive,≤1:40 is negative. Result 234 of the 1482 patients are positive with MP-IgM, the positive rate is 15.79%, the highest consistence is 1:1280.The youngest who can be detected the MP-IgM is 3 months old and the oldest is 83 years old. There isn't remarkable difference between man and woman but the age and season have great influence in the positive rate, p<0.01. Conclusion Mycoplasma pneumonia can cause respiratory infection all the seasons, the positive rate is especially high in winter and spring, 6 to 14 years old children have the highest incidence. MP-IgM should be more detected in respiratory infection patients so as to provide the diagnosis and treatment proofs for clinic, avoid abusing antibiotic. Detecting MP-IgM with the indirect agglutination test is easy, quick and suitable for clinic.
