【摘要】 目的:探讨婴幼儿肺炎支原体肺炎的临床特点。方法:对比研究38例婴幼儿肺炎支原体肺炎与133例儿童肺炎支原体肺炎的临床资料、实验室检查及影像学检查结果。结果:婴幼儿组住院前病程显著长于儿童组(10.26±5.30 vs.7.70±6.42,P<0.05),喘息显著多于儿童组(7.89%vs.3.76%,P<0.05);肺外合并症中,婴幼儿组消化系统症状和心肌损伤多见;儿童组发热多见,伴多种肺外表现。实验室检查,除婴幼儿组的肌酸激酶同功酶(CK-MB)和儿童组的C反应蛋白显著升高外,其余在正常范围或轻度升高。影像学上,婴幼儿组支气管肺炎多见,后者节段性实变较多见。2组大环内酯类治疗均有效,住院天数无显著性差异。结论:婴幼儿肺炎支原体肺炎喘息多见,影像学以支气管肺炎表现较多,而儿童肺炎支原体肺炎发热较多见,多累及节段。更多还原

【Abstract】 Objective:To investigate the clinical characteristics of mycoplasma pneumoniae pneumonia(MPP)in children with different ages.Methods:A total of 171 children with MPP admitted to our hospital from Aug.2010 to Aug.2013.They were analyzed by dividing into two age groups:the younger group(infant and young children≤3 years,n=38)and older group(age>3 years,n=133).Clinical symptoms,main laboratory and imaging results of MPP were compared.Results:Children in younger group had significantly longer duration before admission and higher proportion with wheezing(7.89% vs 3.76%,P<0.05).The gastrointestinal symptoms and myocardial damage were more prevalent in the younger group,while fever and extra-pulmonary manifestations were more common in the older group.Abnormal reatine kinase isoenzyme-MB(CK-MB)in younger group and C-reactive protein in older group was statistically higher than the counterpart(P<0.05).Chest Radiology showed more bronchopneumonia in the younger but more segmental consolidation in the older.Macrolide was effective for both groups.There were no difference in the length of stay in hospital.Conclusion:More infants and young children with MPP present wheezing and bronchopneumonia,in contrast,more patients in the older group presented fever and pulmonary segmental consolidation.更多还原
