摘  要:探讨利用结核分枝杆菌抗原特异性γ-IFN体外释放测定评估抗结核治疗疗效的临床应用价值。研究了66例培养阳性肺结核病人抗结核治疗过程中抗原特异性γ-IFN体外释放测定结果的变化,并与结核菌素皮试结果的变化相比较。结果,抗原特异性γ-IFN体外释放测定于抗结核治疗前期(满2个月)的阳性率显著高于后期(疗程满6个月)[55/66(83.3%)vs12/66(18.2%);P≤0.01],而PPD结素皮试于抗结核治疗前期及后期的阳性率分别为[50/66(75.8%)vs38/66(57.6%);P>0.05]。结论:结核分枝杆菌抗原特异性γ-IFN体外释放测定评估抗结核治疗疗效较PPD结素皮试临床应用价值更大。Practical clinical value of using M. tuberculosis antigen - specific INF - Y release assay (IGRA) in evaluating anti - TB therapeutic result was studied. The change of IGRA responses during anti - TB treatment of 66 patients with culture positive pulmonary tuberculosis was investigated, and compared with PPD tuberculin skin testing(TST). Significantly more patients in the early ( ≤2months of anti -TB treatment)rather than the late phase ( 〉 6months ) had positive IGRA responses [ 55/66 ( 83.3 % ) vsl 2/66 ( 18.2 % ) ; P ≤ 0.01 ], comparing the patients of positive PPD results in the early ( ≤2months of anti -TB treatment) and the late phase ( 〉 6months) [ 50/66 ( 75.8 % ) vs38/66 (57.6%) ; P 〉 0.05 ]. Conclusion is that the antigen - specific INF - Y release assay has higher practical clinical value than PPD tuberculin skin testing(TST) in evaluating anti -TB therapeutic result .
