目的分析血清免疫球蛋白4(immunoglobulin 4,IgG4)、辅助性T细胞17(helper T 17,Th17)/调节性T细胞(regulatory T cells,Treg)评估激素治疗自身免疫性胰腺炎(autoimmune pancreatitis,AIP)患者效果的价值。方法选取铜川市人民医院2021年...目的分析血清免疫球蛋白4(immunoglobulin 4,IgG4)、辅助性T细胞17(helper T 17,Th17)/调节性T细胞(regulatory T cells,Treg)评估激素治疗自身免疫性胰腺炎(autoimmune pancreatitis,AIP)患者效果的价值。方法选取铜川市人民医院2021年4月至2023年9月收治的95例AIP患者,其中男55例,女40例,年龄(54.28±5.51)岁;48例有吸烟史,49例有饮酒史。治疗前,用流式细胞仪检测患者Th17、Treg,计算Th17/Treg,用酶联免疫吸附法检测AMY水平。所有患者均采用激素治疗。根据疗效将患者分为有效组(完全缓解、部分缓解)和无效组(治疗失败)。对比两组患者基础资料和血清学指标。分析血清IgG4、Th17/Treg评估激素治疗AIP患者效果的价值。采用t检验和χ^(2)检验。采用二元logistic逐步回归模型进行影响因素分析,绘制受试者操作特征曲线(ROC)评估预测效能。结果AIP患者激素治疗后,完全缓解43例,部分缓解30例,治疗失败22例,有效率为75.00%(73/95),无效率为23.16%(22/95)。有效组Th17/Treg和D-D、AMY、IgG4水平低于无效组[(1.05±0.14)比(2.21±0.34)、(0.23±0.05)mg/L比(0.52±0.12)mg/L、(296.56±15.74)U/L比(436.26±18.52)U/L、(2.47±0.41)g/L比(4.62±0.78)g/L],差异有统计学意义(t=23.475、16.556、35.005、17.091,均P<0.001)。二元logistic回归分析结果显示,Th17/Treg(OR=4.486,95%CI 1.533~13.125)、D-D水平(OR=3.333,95%CI 1.139~9.753)、AMY水平(OR=3.912,95%CI 1.337~11.445)、IgG4水平(OR=3.077,95%CI 1.052~9.003)是AIP患者激素治疗无效的影响因素(均P<0.05)。ROC分析显示,Th17/Treg、D-D、AMY、IgG4、四者联合预测AIP患者激素治疗无效的灵敏度分别为77.27%、63.64%、68.18%、72.73%、90.91%,特异度分别为76.71%、68.49%、69.86%、73.97%、91.78%。结论Th17/Treg、D-D、AMY、IgG4水平与AIP患者激素治疗无效相关,联合检测预测AIP患者激素治疗效果更为精准且高效。展开更多
