徐州市结核分枝杆菌耐药情况调查

目的了解徐州市结核分枝杆菌的耐药情况。方法采用整群抽样的方法连续收集徐州市城区结核防治门诊2008年8月至2010年4月痰菌阳性的肺结核患者的痰标本193例,用比例法做一线药物（异烟肼、利福平、链霉素、乙胺丁醇）的敏感试验,耐多药的患者做二线药物（左氧氟沙星、阿米卡星、卷曲霉素、丙硫异烟胺）的敏感试验。结果符合条件并纳入调查的细菌有178株;178株结核分枝杆菌总的耐药率为38.8%,初治和复治耐药率分别为21.4%、72.1%,耐多药率为18.0%,初治和复治耐多药率分别为4.3%、44.3%,4种一线药物耐药顺序由高到低分别为耐异烟肼30.3%,耐链霉素29.2%,耐利福平22.5%,耐乙胺丁醇19.1%,复治患者对4种一线药物的耐药率明显高于初治患者;同时耐1种、2种、3种、4种药物的初治和复治耐药率分别为6.8%、8.5%、2.6%、4.3%,9.8%、14.8%、9.8%、29.5%,复治患者同时耐3、4种药物的耐药率明显高于初治者;32例耐多药患者对4种二线药物总耐药率为37.5%,耐药顺序由高到低分别为耐左氧氟沙星28.1%,耐丙硫异烟胺15.6%,耐阿米卡星12.5%,耐卷曲霉素6.3%。结论徐州市结核分枝杆菌整体耐药率仍处于高水平,各部门的结核病防治工作者应采取切实有效的措施,降低耐药结核病的发生。

Drug resistance of Mycobacterium tuberculosis in an epidemiological survey in Xuzhou

Objective To analyze the drug resistance of Mycobacterium tuberculosis(MTB) in Xuzhou.Methods Cluster sampling method was used to collect 193 tuberculosis patients with sputum-positive during 2008-8 to 2010-4 in Xuzhou City.Proportion method was used to test the sensitivity of first-line drugs(isoniazid,rifampicin,streptomycin,ethambutol),the sensitivity of second-line drugs(levofloxacin,amikacin,capreomycin,propylthiouracil isonicotinoyl amines) was tested for the patients with multi-drug resistant(MDR) tu...
