目的探讨血清肺炎支原体(MP)抗体IgM在新疆地区呼吸道感染患儿的阳性检出率及其感染与民族和季节的关系。方法 2010年1月～2011年12月采用被动凝集法对14岁以下呼吸道感染患儿血清中肺炎支原体抗体IgM进行检测。结果 1 000例患儿MP IgM抗体阳性361例,阳性率为36.10%,在9种常见的患儿呼吸道感染性疾病中,支气管炎最高,为54.00%,先天性心脏病合并肺炎最低,为10.00%;各民族呼吸道感染患儿均检出MP阳性,以哈萨克族最高,阳性率为42.11%,汉族其次,为38.95%,维吾尔族最低,为20.69%;秋、冬季的MP抗体阳性率为40.00%,高于春、夏季(31.52%)。结论新疆地区呼吸道感染患儿MP感染率较高,检测MP IgM有利于对呼吸道感染病原体做出诊断,为治疗提供依据。
Objective To investigate the positive detection rate of serogroup Mycoplasma pneumoniae (MP) antibody IgM in children with respiratory tract infection in Xinjiang and its relationship with nationality and season. Methods From January 2010 to December 2011, IgM of Mycoplasma pneumoniae serum was detected by passive agglutination in children under 14 years old with respiratory tract infection. Results The positive rate of MP IgM antibody in 1 000 children was 361%. The highest prevalence of bronchitis was 54.00% in 9 common respiratory diseases of children, the lowest was 10.00 in congenital heart disease complicated with pneumonia % Respectively. The positive rate of MP was 42.11% in Kazak nationality, 38.95% in Han nationality and 20.69% in Uyghur nationality. The positive rate of MP antibody in autumn and winter was 40.00 %, Higher than spring and summer (31.52%). Conclusions The prevalence of MP in children with respiratory tract infection in Xinjiang is high. Detecting MP IgM is helpful to diagnose the pathogen of respiratory tract infection and provide the basis for treatment.
