摘　　要：目的:对照分析迁移性细菌性支气管炎(PBB)的临床特征及病原学特点。方法:回顾性分析2014年6月至2016年12月温州医科大学附属第二医院育英儿童医院收治的湿性咳嗽>4周,并行支气管镜检查和支气管肺泡灌洗液(BALF)细菌培养及细胞学检查的98例患儿的临床资料。BALF细菌培养阳性和(或)中性粒细胞升高,抗菌药物治疗2周咳嗽明显好转者归为PBB组(50例),不符合PBB诊断标准者归为非PBB组(48例)。结果:PBB组男36例,女14例,中位年龄3.2岁,与非PBB组比较差异无统计学意义(P>0.05);平均住院时间(7.0±1.0)d,明显长于非PBB组(P<0.05)。PBB组30例伴喘息,占60%,明显高于非PBB组(P< 0.05);6例(占12%)合并气管狭窄,5例(占10%)合并气管-支气管软化,14例合并鼻窦炎。PBB组BALF中性粒细胞比例为0.63(0.50,0.82),显著高于非PBB组(P<0.01),肺炎链球菌(n=19)为主要致病菌,其次为流感嗜血杆菌(n=5)。PBB患儿均接受2~4周抗感染治疗,其中48例(占96.0%)口服阿莫西林/克拉维酸钾。随访1年,其中23例(占47.9%)PBB复发。结论:PBB好发于婴幼儿,易伴喘息,可合并鼻窦炎。肺炎链球菌为主要致病菌,阿莫西林/克拉维酸钾为首选的治疗药物。Objective： To analyze the clinical characteristics and etiology in children with protracted bacte-rial bronchitis （PBB） confrmed by bronchoscopy. Methods： The hospitalized children who had over 4 weeks cough from June 2014 to December 2016 were investigated retrospectively. The children were defned as PBB （n=50） who had a chronic wet cough without signs of an alternative specifc cause and responding to 2 weeks of appropriate antibiotics, had positive bacterial culture and/or increased of neutrophils in bronchoalveolar lavage fuid （BALF）. Those did not fulfll the above criteria were divided into the ‘no PBB group’ （n=48）. Results： In the PBB group, there were 36 boys and 14 girls. The median （IQR） age was 3.2 （2.0~4.0） years and 58.0% cases were under 3 years. Thirty children were accompanied by wheezing. Airway malacia were found in fve cases. The average of neutrophils in BALF was 0.63 （0.50, 0.82）, which was signifcantly higher than that in the control group （P〈0.01）. 36 isolates were identifed from BALF in children with PBB, the common pathogens were Strep-tococcus pneumoniae （n=19）, Haemophilus infuenzae （n=5） and Moraxella catarrhalis （n=4）. All children re-ceived a 2~4 weeks course of antibiotics. The majority （n=48） received oral amoxicillin/clavulanic acid. Twenty-three cases （47.9%） had a recurrent PBB by 1 year follow-up. Conclusion： PBB occurs mainly in younger chil-dren and often co-exist with wheezing. Streptococcus pneumoniae is the leading pathogen in children with PBB. Amoxicillin/clavulanic acid is the major treatment for PBB.
