北京地区1990～1991年支原体肺炎临床研究

A CLINICAL STUDY ON MYCOPLASMAPNEUMONIA SEEN BETWEEN 1990 AND 1991Wang

１９９０～１９９１年北京地区支原体肺炎（ＭＰ）感染流行，我院应用间接血凝试验（ＩＨＡ）检测肺炎支原体血清抗体８４例，双份血清恢复期抗体上升４倍以上，或急性期抗体滴度＞１：３２者有８０例，占９５．２％，婴幼儿占１５％。婴幼儿支原体肺炎与儿童比较发热高者多，呼吸困难及肺部体征多，肺外表现少，Ｘ线改变间质型占优势，并对ＭＰ合并神经根炎和心肌心包炎等肺外表现作简要介绍。

AbstractThere was an epdemic of mycoplasma pneumonia(MP) in northern China from 1990 to 1991. Serumspoimens of 84 cases were tested for antibody tomycoplasma pneumoniae by using indirecthemagglutination test. Four-fold or more increase ofserum antibody to mycoplasma pneumoniae duringthe conralescent stage and antibody titers > 1 : 32were seen in 80 cases (95.2%), including 12 infants(12 / 80). Comparing infants to children, MP of in-fants had the following characteristics: high fever (>40℃ ,41.7% vs 17.6%), dyspnea (25% vs 1.4%).postivie findings on chest examination (75% vs30.9%), less common nonrespiratory manifstations(8.3% vs 23.6%). The serious nonrespiratory compli-cations of MP were cardiac damage and central nery-ous system involvement.
