老年呼吸道感染者血清肺炎支原体抗体检测及临床意义

The detecfion of serum mycoplasma pneumonia antibody in elderly patients with respiratory tract in fection

本文应用间接血凝法对１２５例老年呼吸道感染患者，９７例老年对照组及９２例非老年呼吸道感染患者进行血清肺炎支原体抗体的检测。结果发现老年呼吸道感染组血清肺炎支原体抗体阳性率明显高于老年对照组（Ｐ＜０．０１）。与非老年呼吸道感染组相比无显著性差异（Ｐ＞０．０５）。说明肺炎支原体已成为老年呼吸道感染的常见病原体之一。

Li Liyun,Yu Runjing.The First Affiliated Hospital of China Medical University. Shenyang 110001 Mycoplasma pneumonia was a community acquired infection occurring primarily in children and young adults. Mycoplasma pneumoniae infection in the elderly has not been systematically studied. In the present study mycoplasma pneumoniae IgM antibodies were detected in serum of three groups with indirect hemagglutination assay. Group 1 consisted of 125 elderly patients with respiratory tract infection, group 2 ,92 middle aged and young patients with respiratory tract infection, and group 3, 97 elderly control subjects without respiratory disease.Results:positive rate in group one was 28 8 percent which was significanty higher than that of the control ( P >0 01),but showed no significant difference with group two whose positive rate was 29 3 percent ( P >0 05).Conclusion:mycoplasma pneumonia was one of the common pathogens in the elderly with respiratory infection.
