A comparative study on the clinical presentation of Mycoplasma pneumoniae infection was performed in 56 patients with pleuropneumonia and those who had pneumonia without pleural effusion. The latter consisted of 773 cases; their age distribution reached a peak at 3-5 years of age in males and at 4-6 years in females. The 56 cases with pleuropneumonia were distributed among children of all ages. Pneumococcal infection was demonstrated by blood culture in one of 56 cases. Serological tests revealed a higher prevalence of mixed viral infections among children with pleuropneumonia (18/44) than with pneumonia but no effusion (69/419). There was a tendency toward a severe and prolonged course of illness with strong indications of infection among pleuropneumonia cases. Complications such as exanthema or liver dysfunction were observed more frequently among pleuropneumonia cases than among simple pneumonia cases. These results suggest that other pathogenic agents or unknown host reactions to these agents may modify the clinical picture of pleuropneumonia caused by M. pneumoniae.
对56例胸膜肺炎患者和无胸腔积液的肺炎患者的肺炎支原体感染临床表现进行了比较研究。后者包括773例；其年龄分布在男性3 - 5岁、女性4 - 6岁时达到峰值。56例胸膜肺炎患者分布在各年龄段儿童中。56例中有1例血培养证实为肺炎球菌感染。血清学检测显示，胸膜肺炎患儿（18/44）混合病毒感染的患病率高于无积液肺炎患儿（69/419）。胸膜肺炎病例有病情严重且病程延长的趋势，并有强烈的感染迹象。与单纯肺炎病例相比，胸膜肺炎病例更频繁地观察到皮疹或肝功能障碍等并发症。这些结果表明，其他病原体或宿主对这些病原体的未知反应可能会改变肺炎支原体引起的胸膜肺炎的临床表现。
