摘要:
目的 探讨结核感染T细胞斑点试验(T-SPOT.TB)对肺结核治疗效果的监测意义。 方法 采用T-SPOT.TB试剂盒,检测其抗原ESAT-6和CFP-10的应答,对比79例活动性肺结核患者治疗前与治疗2月末及治疗结束时ESAT-6和CFP-10应答结果的变化。 结果 79例活动性肺结核患者,ESAT-6和CFP-10应答的斑点数在治疗2月末和治疗结束时较治疗初均有明显下降,与治疗初比较,差异均有统计学意义(P < 0.05)。ESAT-6和CFP-10在治疗2月末和治疗结束时阴性率较治疗初有上升,与治疗初的阴性率比较,差异无统计学意义( P > 0.05);全部患者T-SPOT.TB转阴率为3.8%。治疗2月末与治疗结束时ESAT-6应答变化,差异有统计学意义( χ2 = 4.635,P = 0.031 < 0.05);治疗2月末与治疗结束时CFP-10应答变化,差异无统计学意义( χ2 = 1.272,P = 0.259 > 0.05)。 结论 T-SPOT.TB治疗前后ESAT-6、CFP-10应答变化有明显差异,对肺结核治疗效果评价有一定作用,但不能利用其转阴率作为肺结核治疗停药指标。 -

Abstract:Objective To explore the significance of T-SPOT.TB test for monitoring the therapeutic effect of tuberculosis. Methods Using T-SPOT.TB kit, changes in response to ESAT-6 and CFP-10 were compared in 79 patients with active pulmonary tuberculosis before and after 2 months of treatment. Results In 79 patients with active pulmonary tuberculosis, The spot number of ESAT-6 and CFP-10 responses decreased significantly at the end of 2 months and at the end of treatment compared with the beginning of treatment, and the difference was statistically significant(P < 0.05). The negative rates of ESAT-6 and CFP-10 at the end of 2 months and at the end of treatment were higher than those at the beginning of treatment, but there was no significant difference between them( P > 0.05). The T-SPOT.TB negative conversion rate of all patients was 3.8%.There was a statistical difference in ESAT-6 response between the end of 2 months and the end of treatment( χ2 = 4.635, P = 0.031 < 0.05).There was no significant difference in CFP-10 response at the end of treatment 2 and at the end of treatment( χ2 = 1.272, P = 0.259 > 0.05). Conclusion There were significant differences in ESAT-6 and CFP-10 of T-SPOT.TB responses before and after treatment. T-SPOT has a certain significance in evaluating of the therapeutic effect of tuberculosis, but its negative conversion ration can not be used as the indicator of ending the TB treatment. -
