摘　　要：目的:探究血清游离三碘甲状腺原氨酸(FT3)、游离四碘甲状腺原氨酸(FT4)、FT3/FT4、促甲状腺激素(TSH)对克罗恩病(CD)患者维得利珠单抗(VDZ)治疗后临床应答的预测价值。方法:纳入2020年5月至2022年5月我院接受VDZ治疗且疗程超过3个月的CD患者54例,对照组89例。收集对照组及CD患者使用VDZ治疗前、治疗3个月后FT3、FT4、FT3/FT4、TSH等甲状腺功能指标数据,用CD活动指数(CDAI)评估CD疾病活动度。比较CD患者与对照组甲状腺功能指标差异。根据VDZ治疗前后CDAI差值(ΔCDAI)是否≥100分分为应答组及无应答组,比较两组患者VDZ治疗前后甲状腺功能指标变化及其差值(ΔFT3、ΔFT4、ΔFT3/FT4、ΔTSH)与ΔCDAI相关性;用受试者工作特征(ROC)曲线分析上述差值对VDZ临床应答的预测价值。结果:CD患者治疗前FT3、FT3/FT4低于对照组(P<0.05);VDZ治疗3个月后FT3、FT3/FT4较前提高,FT4降低(P<0.05)。应答组FT3、FT4、FT3/FT4、CDAI在VDZ治疗前后自身比较,差异均有统计学意义(P<0.05)。VDZ治疗前后ΔFT3、ΔFT3/FT4与ΔCDAI间呈负相关(P<0.05),ΔFT4、ΔTSH与ΔCDAI无直线相关关系(P>0.05)。ΔFT3、ΔFT3/FT4预测VDZ治疗临床应答潜能的ROC曲线下面积(AUC)分别为0.837、0.827,灵敏度为82.9%、80.5%,特异度均为81.8%。结论:血清游离甲状腺功能指标变化尤其是FT3、FT3/FT4变化与CD患者VDZ治疗后临床活动指数变化呈负相关,并对其临床应答有一定预测价值。Objective:To investigate the predictive value of serum free triiodothyronine(FT3),free tetraiodothyronine(FT4),FT3/FT4 and thyroid stimulating hormone(TSH)on clinical response to Vedolizumab(VDZ)in patients with Crohn s disease(CD).Methods:From May 2020 to May 2022,54 patients with CD who received VDZ treatment for more than 3 months in our hospital and 89 healthy control cases(the control group)were included.FT3,FT4,FT3/FT4,TSH and other data of the control group and CD patients were collected before and 3 months after VDZ treatment.CD activity index(CDAI)was used to evaluate CD disease activity.The difference of thyroid function between CD group and the control group was compared.According to whether the difference of CDAI(ΔCDAI)before and after VDZ was more than 100 points,CD patients were divided into response group and non-response group.The changes of thyroid function indexes before and after VDZ treatment and the correlation between the differences(ΔFT3,ΔFT4,ΔFT3/FT4,ΔTSH)andΔCDAI were compared between the two groups.The predictive value of the above difference to VDZ clinical response was analyzed by using receiver operating characteristic(ROC)curve.Results:Before treatment,FT3 and FT3/FT4 in CD patients were lower than those in the control group(P<0.05).After 3 months of VDZ treatment,FT3 and FT3/FT4 were increased,while FT4 was decreased(P<0.05).FT3,FT4,FT3/FT4 and CDAI in the response group were compared before and after VDZ treatment,and the differences were statistically significant(P<0.05).Before and after VDZ treatment,ΔFT3,ΔFT3/FT4 were negatively correlated withΔCDAI(P<0.05),while there was no linear correlation betweenΔFT4,ΔTSH andΔCDAI(P>0.05).The area under curve(AUC)ofΔFT3 andΔFT3/FT4 to predict the clinical response potential of VDZ treatment were 0.837 and 0.827,respectively,with sensitivity of 82.9%and 80.5%and specificity of 81.8%.Conclusion:The changes of serum free thyroid function indexes,especially FT3 and FT3/FT4,are negatively correlated with the changes of clinical ac
