摘要: 目的 探讨比例法和绝对浓度法测试分支杆菌耐药性的一致性和可比性,对乙胺丁醇的效价计算方法进行分析探讨。方法 对第四次全国结核病流调分离的 453株分支杆菌用比例法和绝对浓度法同时进行 4种抗结核药物(INH、SM、RFP、EMB)的耐药性测定,并用二种效价计算方法对乙胺丁醇的耐药性进行对比试验。结果 402株结核分支杆菌用二种方法测试的四种药物的耐药率均无显著性差异 (P>0.05),51株非结核分支杆菌中,除EMB用比例法测试的耐药率明显高于绝对浓度法外 (P<0.01),其余 3种药物二种方法测试的耐药率无显著性差异。H、S、R、E二种方法测试结果的一致率分别为 96.2%、97.1%、98.7%和 96.9%。EMB用二种效价计算方法检测结果的一致率为99.1%。结论 用比例法和绝对浓度法进行结核分支杆菌耐药性测定的一致性较高,药敏试验方法向比例法转轨,不会影响与我国既往资料的连续性和可比性。建议今后工作中对EMB的效价计算方法加以改进。

Abstract: Objective To analyze the comparability between proportion method and absolute concentration method in drug susceptibility testing (DST).Methods 453 isolates from nationwide epidemiological survey were subjected to susceptibility testing against 4 anti tuberculosis drugs using both proportion method and absolute concentration method.Results The resistance to each of 4 drugs in 402 M.tuberculosis isolates did not show statistically significant difference between two methods.In 51 NTM isolates,only was the resistance to EMB significantly higher in proportion method than in absolute concentration method.The accordance rate between two Methods was 96.2%、97.1%,98.7% and 96.9% for INH,SM,RFP and EMB respectively.Conclusion The accordance between proportion method and absolute concentration method is high,and the Results obtained by using proportion method are comparable with both international standard and previous data of our country.
