摘要: 目的分析淮安地区住院及门诊随访患者痰标本中分离出的结核分枝杆菌对4种常用抗结核药物的耐药情况,比较初治及复治患者对4种结核药物的敏感度差异,为临床治疗提供用药参考,减少经验用药加强规范合理用药减少结核分枝杆菌耐多药率的发生。方法采用比例法 对350株结核分枝杆菌进行两种一线抗结核药(异烟肼,利福平)两种抗结核药(氧氟沙星,卡那霉素)敏感性测定。结果350株结核分枝杆菌总体耐药率为37.7%(131/350),而初治耐药率为30.4%(71/233),复治耐药率为51.3%(60/117)。另外350株结核分枝杆菌的总体耐多药率为15.4%(54/350),而初治耐多药率为11.2%(26/233),复制耐多药率为23.9%(28/117)。与全国第五次结核病流行病学调查比较耐药率及耐多药率均有提高。结论复治肺结核患者分离出的结核分枝杆菌耐药率及耐多药率均较初治患者高。加强患者管理,规范治疗对初治患者尤为重要。

Abstract: ObjectiveDrug resistance of Mycobacterium tuberculosis to four common antituberculosis drugs in sputum of tuberculosis patients was analyzed; difference in sensitivity of four common antituberculosis drugs was compared between initial treatment and retreatment tuberculosis patients, which all provide a reference for clinic treatment to reduce the incidence of multidrug resistance of Mycobacterium tuberculosis. MethodsUsing the ratio method, 350 strains of Mycobacterium tuberculosis were tested for the susceptibilities to two firstline antituberculosis drugs (isoniazid and rifampicin) and two secondline antituberculosis drugs (ofloxacin and kanamycin). ResultsThe total resistant rate of 350 strains was 37.7% (131/350), while that of initial treatment patients and retreatment patients was 30.4%(71/233) and 51.3%(60/117). Furthermore, the total rate of multidrug resistance was 15.4%(54/350), the multidrug resistance rate of initial treatment was 11.2%(26/233), while that of retreatment patients was 23.9% (28/117). Compared with the results of the fifth national epidemiological survey of tuberculosis, the drug and multidrug resistance rate both increased. ConclusionThe drug and multidrug resistance rate of Mycobacterium tuberculosis from the retreatment tuberculosis patients were higher than the strain from initial treatment tuberculosis patients. It is crucial for the initial treatment patients to strengthen the standard treatment management.
