目的 研究慢性呼吸道疾病并發(fā)社區(qū)獲得性下呼吸道細菌感染住院患者的病原菌分布。方法 回顧性分析2001年~2005年在北京大學第三醫(yī)院呼吸病房住院的212例社區(qū)獲得性下呼吸道細菌感染患者的臨床資料、痰培養(yǎng)及藥敏結果,患者均具有慢性呼吸道基礎疾病。結果 臨床分離病原菌229株,革蘭陰性桿菌為主。慢性阻塞性肺疾病急性加重期患者感染的病原菌中革蘭陰性桿菌占73.9%,銅綠假單胞菌和肺炎克雷伯菌最常見,分別為18.2%和13.6%;革蘭陽性球菌占23.8%,其中金黃色葡萄球菌10.2%,肺炎鏈球菌9.1%。支氣管擴張癥患者感染時革蘭陰性桿菌占86.2%,前三位分別為銅綠假單胞菌(27.5%)、副流感嗜血桿菌(13.7%)和流感嗜血桿菌(11.8%)。Logistic回歸分析發(fā)現(xiàn)感染銅綠假單胞菌的危險因素為患有支氣管擴張癥(OR=5.590,95%CI 2.792~11.192);感染鮑曼不動桿菌的危險因素為1月內(nèi)使用制酸劑(OR=9.652,95%CI 2.792~11.192)和低蛋白血癥(OR=2.679,95%CI 1.108~6.476);感染腸桿菌科細菌(包括肺炎克雷伯菌、陰溝腸桿菌和大腸埃希菌)的危險因素為前1月內(nèi)使用抗菌藥物(OR=4.236,95%CI 1.982~9.057),以及患有腎臟疾?。∣R=4.305,95%CI 1.090~17.008)和糖尿?。∣R=2.836,95%CI 1.339~6.009)。結論 患有慢性呼吸道疾病患者并發(fā)社區(qū)獲得性下呼吸道感染時的病原菌以革蘭陰性桿菌為主,根據(jù)基礎疾病、病情嚴重程度和用藥史的不同而變化,對病原菌的正確判斷有助于制定合理的經(jīng)驗性抗感染方案。
