【摘要】 目的 了解部队结核病患者耐药状况,为防治提供依据。方法 应用改良罗氏培养基。采用绝对浓度间接法对1995年1月—2004年12月收治的586例军人结核病患者痰标本进行异烟肼利福平链霉素乙胺丁醇四药的药敏实验。结果 586例患者痰培养获得结核分枝杆菌79株, 其中耐药菌株45株, 耐药率57.0%(45/79)。 耐1药率、耐2药率、耐3药率及耐多药率分别为31.6%,13.9%,2.5%及8.9%,分别占所有耐药患者的556%, 24.4%, 4.4%15.6%, 以耐1药为主。 利福平异烟肼乙胺丁醇链霉素耐药率分别为20.3%,21.5%,24.1%及30.4%。结论 部队结核病患者耐药状况不容乐观,必须采取多种措施加强部队结核病控制工作。

Abstract: Objective To evaluate the situation of amituberculosis drug resistance in military patients with pulmonny tuberculosis and find out the scientific basis of tuberculosis control.Methods The sputom samples of 586 military patients with pulmonny tuberculosis hospitalized from Januny 2005 to December 2004 were cultured and tested for resistance to Isoniazid (H), Rifampicin (R), Ethambutol (E) and Streptomycin (S) by the absolute concentration method.Results 79 strains of tuberculous mycobacterium were obtained,drug resistan strains were 45, the fate of drug resistance was 57.0%(45/79) .The rates of drug resistance to onedrug, to twodrug,to threedrug and to multidug were 31.6%,13.9%,2.5% and 8.9% respectively.The fates of drug resistance to R, H, E and S were 20.3%,21.5%, 24.1 and 30.4% respectively.Conclusion The drup resistance of military patients with pulmonny tuberculosis was serious.Effective methods should be taken to control tuberculosis in the army.    Key words: army;tuberculosis;drugresistance。

随着耐药结核病疫情的上升,特别是多耐药结核病的出现,严重影响了结核病的化疗效果,给结核病的控制带来极大困难。为了解部队结核病患者耐药情况,为防治提供依据,回顾分析了我科收治的军人结核病患者耐药情况,现报告如下。

1 资料与方法。

1.1 病例来源。

以1995年1月—2004年12月我科收治的586例军人结核病患者为研究对象,所有患者于诊断后3 d 内系统抗结核治疗前,行痰集结核菌检查3次和痰结核菌培养+药敏1次。

1.2 检测方法。

应用改良罗氏培养基,按照《结核病诊断细菌学检验规程》[1]进行菌型鉴定,采用绝对浓度间接法对异烟肼(H)、利福平(R)、乙胺丁醇(E)、链霉素(S)四种抗结核药进行药敏试验。

1.3 质控方式。

每批试验均以结核分支杆菌参考菌株(H37RV敏感菌株)10—5mg 作为质控。

1.4 耐药及耐多药判定标准。

耐药(Drug resistance,MR)指耐H,R,E,S中任一药物;耐多药(Multidrug resistance,MDR)指至少对包括H和R在内的两种及两种以上抗结核药物耐药[2]。
