目的:了解天津地区2008～2009年肺炎支原体(MP)肺炎的临床特征,总结治疗体会。方法:选择天津地区4 037例住院肺炎患儿,对患儿的发病季节、年龄、临床表现、肺外并发症进行统计。结果:4 037例中MP肺炎374例,发病率9.26%,5岁以上为主(67.38%),年长儿中,高热、干咳为主要临床表现,肺内炎性实变多见,且多合并病毒感染(39.57%)。1/4发生胸膜病变。肺外损害中,除皮疹、消化道症状,出现1例肾炎,最严重为3例噬血细胞淋巴细胞增殖综合征(HLH)。神经系统损害少见。结论:MP感染是社区获得性肺炎的主要致病原,除引起肺部病变,尚可引起肺外多脏器和组织的损害,应注意早期诊断和综合治疗。
