【摘要】:背景: 慢性阻塞性肺疾病(COPD)是一种以气道、肺实质和肺血管慢性炎症导致气流受限不完全可逆为特征的呼吸系统的常见病。由于C0PD患病人数多,死亡率高,社会经济负担沉重,已成为一个重要的公共卫生问题。就世界平均水平而言,居当前死亡原因的第4位。根据世界银行/世界卫生组织发表的研究结果,至2020年COPD将跃升至世界疾病经济负担的第5位。呼吸道感染是COPD加重、恶化的重要因素,预防呼吸道感染,减少COPD急性发作对于节约社会成本,降低医疗负担,提高COPD患者生存质量有重大意义。 目的: 通过对慢性阻塞性肺疾病(COPD)患者急性加重期及稳定期病原菌分布情况进行分析,为进一步制定有针对性的干预对策提供理论依据。 方法: 分析我院2010年7月至2012年6月呼吸科收治的1107例慢性阻塞性肺疾病急性加重期(AECOPD)患者痰液细菌培养结果,对307例痰培养结果阳性患者于稳定期行痰液细菌培养,以痰中病原菌浓度≥107CFU/ml作为诊断C0PD病原菌感染的标准。对稳定期及急性加重期痰培养结果进行分析,,并结合有统计学意义的一般临床特征制定COPD患者急性加重期及稳定期的干预对策。 结果: 患者的一般临床特征:年龄、WBC、FEVl/FVC、PaO2、PaCO2、CRP、TNF-α、IL-18、IL-13急性加重期明显高于稳定期(P0.05)。急性加重期合格痰标本389份,痰标本合格率35.1%,检出141株菌≥107CFU/ml,G-杆菌占67.4%(95株),其中以铜绿假单胞菌、鲍曼不动杆菌、嗜血杆菌多见;G+球菌占18.4%(26株),以肺炎链球菌、金黄色葡萄球菌、溶血葡萄球菌为主;真菌占14.2%(20株),曲霉菌11株,念珠菌9株;痰细菌培养阳性率为36.2%;稳定期合格痰标本307份,痰标本合格率78.9%,检出35株菌≥107CFU/ml,G-杆菌占74.2%(26株),其中铜绿假单胞菌分离率最高,占40.0%(14株),真菌占20.0%(7株),G+球菌占5.8%(7株);痰细菌培养阳性率为11.4%。急性加重期与稳定期痰培养阳性结果相同31株(31例患者),其中13例支气管扩张,11例合并有2型糖尿病、高血压病、冠心病,4例合并骨折,3例无基础疾病。 结论: AECOPD住院患者痰标本合格率低;病原菌以革兰阴性杆菌为主;急性加重期痰培养阳性率低,非细菌感染因素导致的COPD病情加重不容忽视;稳定期由于人为干预痰标本合格率明显升高,但痰培养结果阳性率更低,且多为合并有支气管扩张、2型糖尿病等基础性疾病,细菌定植在普通COPD患者急性发作中的作用值得思考。在COPD患者不同时期给予相应干预措施提高痰标本合格率、增强患者自身免疫力,有助于减少经验性用药、缩短住院时间、避免医疗资源浪费及住院费用过多。
[Abstract]:Background: chronic obstructive pulmonary disease (COPD) is a common respiratory disease characterized by chronic inflammation of airway, lung parenchyma and pulmonary vessels, which leads to incomplete reversible airflow restriction. Because of the high number of C0PD, high mortality and heavy social and economic burden, it has become an important public health problem. In terms of the world average, it ranks fourth among the current causes of death. According to a study published by the World Bank / World Health Organization, COPD will jump to fifth place in the world's disease economic burden by 2020. Respiratory tract infection is an important factor for the aggravation and deterioration of COPD. It is of great significance to prevent respiratory tract infection and reduce the acute attack of COPD in order to save social cost, reduce medical burden and improve the quality of life of COPD patients. Objective: to analyze the distribution of pathogenic bacteria in patients with chronic obstructive pulmonary disease (COPD) during acute aggravation and stable stage, and to provide theoretical basis for further formulation of targeted intervention strategies. Methods: from July 2010 to June 2012, 1107 patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) were treated with sputum bacterial culture. Sputum bacterial culture was performed in 1107 patients with positive sputum culture results. The sputum pathogen concentration 鈮
