摘要
目的分析喹诺酮耐药大肠埃希菌尿道感染现状及危险因素,为临床合理选用抗生素提供依据。方法回顾性分析348例大肠埃希菌尿道感染临床现状,以喹诺酮敏感大肠埃希菌为对照菌株,对喹诺酮耐药大肠埃希菌感染危险因素进行分析。结果 348株大肠埃希菌尿道感染中检出喹诺酮耐药菌203株,占58.3%。Logistic回归分析显示三代头孢菌素及喹诺酮类药物使用、尿路引流和细菌产超广谱β-内酰胺酶是喹诺酮耐药大肠埃希菌感染的独立危险因素。结论尿道感染大肠埃希菌中喹诺酮耐药株的检出率高、耐药性强,其感染患者平均住院时间长、医疗费用高。喹诺酮耐药菌株感染具有多个危险因素,加强对这些危险因素的控制有助于预防耐药菌株感染的扩散。
Objective To investigate the quinolone resistant Escherichia coli infection status and risk factors, and provide a basis for selecting appropriate antibiotics in the clinical practice. Methods This study is a retrospective review from 2010 to 2011. 348 strains Escherichia coli isolated from urine specimens were analysis, using the quinolone susceptible isolates as the control group. The risk factors for the quinolone resistance strains were analyzed. Results Of the 348 E.coli strains isolated from urinary tract infection patient, 58.3% （203）were quinolone resistant. Logistic regression analysis showed three generation cephalosporins and quinolones drug use, urinary drainage and bacterium producing extra-broad spectrum beta-lactamase were the independent risk factors for ciprofloxacin resistance of E.coli strains isolated from urinary tract infection patients. Conclusion The epidemic of quinolone resistant Escherichia coli isolated from urine specimens were extremely serious. The drug resistance of the quinolone resistant isolates was strong. The patients infected with quinolone resistant strains had high medical cost and longer average length of stay in hospital. The quinolone resistant E.coli infection with multiple independent risk factors, the strengthening of these independent risk factor controls can effectively prevent the spread of quinolone resistant strains infection.
