结核病耐药的影响因素分析

目的分析结核病患者的耐药状况,讨论应对计策,为耐药结核的治疗提供参考。方法对结核患者的临床分离株进行菌种鉴定,对鉴定为结核分枝杆菌的临床分离株进行药物敏感检测。采用绝对浓度法的间接法,药敏试验的药物采用临床治疗的常规药物。结果结核分枝杆菌的总耐药率为27.28%,异烟肼、利福平耐药状况最为突出,其耐药率分别为16.65%、14.24%。治疗方案合理、规则用药、治疗中断、患者的个人收入及既往治疗史是结核病患者耐药发生的影响因素。结论单一耐药的比例下降,但是耐药菌的发展趋势是多重耐药,这为临床上采用的以此二种药物为主的四联疗法构成了挑战。

Analysis of drug resistance in tuberculosis patients

Objective To analyze patients with tuberculosis resistance situation and discuss strategies in order to provlOe the reference for the treatment of drug-resistant TB. Methods We identified the clinical separation plant species of the tu- berculosis patients and used the clinical drug sensitive detection with absolutely concentration for the separation plant i- dentified as mycobacterium tuberculosis. The drug which we used in susceptibility test were conventional drugs. Results The total resistance of myeobacterium tuberculosis was 27.28%, the resistance of isoniazid,rifabutin were the most out- standing and the resistance were 16.65%, 14.24% respectively. Reasonable treatment options, rules, medication, treatment interruption, personal income and prior treatment history of patients were the influencing factors with TB drug resistance. Conclusion The single drug resistance ratio drops, but drug-resistant bacteria is multiple resistance, this situation pose is great challenges for clinical used with two kinds of drug primarily quad therapy.
