摘要: 目的  为验证线性探针技术快速检测耐多药肺结核在基层结核病防治工作中可行性。方法  对459例涂阳肺结核患者痰标本应用线性探针技术快速检测耐利福平、耐异烟肼菌株,同时进行传统罗氏培养和药敏试验结果相比较。结果  线形探针技术与传统药敏试验检测RFP耐药率分别为5.9%(27/459)和6.3%(29/459),差异无统计学意义(χ2=0.038,P>0.05);INH耐药率分别为8.7%(40/459)和10.0%(46/459),差异无统计学意义(χ2=0.231,P>0.05)。两种方法检测对RFP均敏感者427例,均耐药者24例,二者结果一致率98.3%(451/459);对INH均敏感者410例,均耐药者37例,二者结果一致率97.4%(447/459)。两种方法检测耐利福平的灵敏度为82.8%(24/29),耐异烟肼的灵敏度为80.4%(37/46),耐利福平、异烟肼特异度均为99.3%(427/430)。结论  应用线性探针技术检测耐多药肺结核与传统药敏试验相比,利福平、异烟肼耐药检出率差异无统计学意义。其特异度高,是快速检测耐多药肺结核的诊断方法。

Abstract: Objective  To evaluate the feasibility of using a line probe assay to detect multidrug-resistant tuberculosis (MDR-TB) in the grass-roots work of preventing and controlling TB.  Methods  459 sputum samples from smear-positive patients with pulmonary tuberculosis were examined rifampicin- and isoniazid-resistance by a line probe assay and conventional drug susceptibility testing. Results  The rifampicin- and isoniazid-resistant rates from line probe assay (5.9%, 27/459; 8.7%, 40/459) had no significant difference with those (6.3%, 29/459; 10.0%, 46/459) from the conventional drug susceptibility testing (χ2=0.038,P>0.05; χ2=0.231,P>0.05). Their concordance was 98.3%(451/459)for the rifampicin resistance and 97.4%(447/459)for the isoniazid resistance. Conclusion The line probe assay is a rapid, specific and feasible method for the early diagnosis of MDR-TB in the grassroots.
