肺炎支原体感染肺外并发症118例

Clinical Analysis of Extra-pulmonary Complications in 118 Cases with Mycoplasm Pneumoniae Infection

目的分析肺炎支原体(MP)感染肺外器官受损的临床特征、疗效及预后。方法采用ELISA法检测MP IgM、IgG,对阳性的且鼻咽部洗液呼吸道病毒检测和呼吸道分泌物细菌培养均为阴性的226例患儿临床资料进行回顾性分析。结果226例中118例肺外多器官受累,占52.20%,其中以消化、泌尿、心血管系统及浆膜腔积液多见,分别为38.98%、33.89%、21.11%和17.79%。均经大环内酯类抗生素治疗14d好转。MP IgM均阳性,IgG阳性率35.5%,痰MP培养阳性率32.20%,冷凝集试验阳性率47.46%。结论MP感染可引起大量肺外并发症,故对不能完全以细菌、病毒感染解释的多脏器受累的呼吸道感染,应考虑到MP感染的可能。

Objective To analyze the clinical features,curative effect and prognosis of extra-pulmonary infections by mycoplasma pneumoniae(MP).Methods ELISA was used to detect anti-MP IgM and IgG.Case histories of 226 patients,whose nasopharyneal lotione and respiratory secretions were positive of virus and bacteria respectively,was analysed retrospectively.Results One hundred and eighteen of the 226 (52.2%) cases suffered from extra-pulmonary infection.Of these infections 38.98%,33.89%,21.11% and 17.79% were found in digestive, urinary, cardiovascular systems and serous membrane respectively.All of the cases were improved after treatment with macrolides antibiotics.All cases were MP IgM positive,35.5% cases were IgG positive.Spatum MP positive rate was 32.2%.Positive rate of cold-agglutination test was 47.46%.Conclusions MP infection may cause many extra-pulmonary complications.When multi-organ infections can not be explained with bacterial and viral infections,MP infection should be considered.
