住院肺结核患者耐药性分析

目的探讨住院肺结核患者的耐药特征,为结核病防治工作提供参考。方法对2006年1月~2008年12月期间住院的痰样本结核分枝杆菌培养阳性肺结核患者的结核分枝杆菌对4种抗结核药物（INH、SM、EMB、RFP）的耐药性测定,并进行回顾性分析。结果 1 586株结核分枝杆菌总的耐药率为30.1%,初始耐药率和获得性耐药率分别为16.0%和56.1%;耐多药率为12.0%,其中初始耐多药率和获得性耐多药率分别为3.1%和28.6%;4种抗结核药物的耐药率从高到低分别为INH（22.5%）、RFP（17.0%）、SM（11.1%）和EMB（6.2%）;耐1种、2种、3种和4种药物的初始耐药率和获得性耐药率分别为10.6%、3.8%、1.2%、0.5%和18.0%、19.2%、13.7%、5.2%,无论是获得性耐药率、耐多药率、耐1种、耐2种、耐3种和耐4种药均显著高于初始耐药率（P〈0.005）。结论住院肺结核患者结核分枝杆菌总耐药率、获得性耐药率尚处于较高水平,获得性耐药更趋向于对多种药物耐药,尤其是获得性MDR-TB发生率较高,应引起注意,需采取综合防治措施降低耐药率。

Determination of drug resistant of pulmonary tuberculosis inpatients

Objective To determine status of drug resisstance of Mycobacterium tuberculosis in pulmonary tuberculosis inpatients for offering reference of preventing and treating tuberculosis.Methods The resisntance of pulmonary tuberculosis inpatients positive for Mycobacterium tuberculosis to INH,SM,EMB and RFP were determned in 2006~2008 Results Of all 1 586 isolates of Mycobacterium tuberculosis,the total drug resistance was 30.1%,the primary drug resistance rate was 16.0% and the acquired drug resistance rate was ...
