婴儿肺炎支原体聚合酶链反应阳性28例分析

Analysis of 28 infants with mycoplasma PCRPositive pneumonia.

目的：研究婴儿肺炎支原体（ＭＰ）感染的临床特点和治疗措施。方法：回顾性总结了ＭＰ－ＰＣＲ阳性的２８例婴儿肺炎。结果与结论：发现ＭＰ－ＰＣＲ阳性者占同期婴儿肺炎住院人数的１１％，其临床表现缺乏特异性，在小婴儿可误诊为百日咳，喘憋明显的恰似毛细支气管炎。肺外表现主要有肝功能和心肌酶谱损害。治疗应注意混合感染的可能。

Objective: To investigate the clinical manifestations and treatment of mycoplasma pneumonia in infants. Methods: Clinical data of 28 infants with mycoplasma (MP) PCRpositive Pneumonia were analyzed. Results and conclusion: MPPCR Positive accounted for 11% of inpatients with pneumonia during the same period of study. The manifestations of these patients were unspecific and might be misdiagnosed as pertussis in young infants. Sometime it might be manifested as capillary bronchitis in those patients with obvious dyspnea. Abnormal liver function or increased cardiogenic enzymes might be seen besides respiratory symptoms and signs. The possibility of mixed infections should also be considered. The third generation of cephalosporin is a good choice of treatment besides erythromycin.
