摘要 目的探讨红细胞分布宽度(RDW)、中性粒细胞与淋巴细胞比值(NLR)及血小板与淋巴细胞比值(PLR)在炎症性肠病(IBD)中的诊断价值。方法收集237例IBD患者和300例体检的健康对照者,测定其外周血血常规,计算NLR和PLR。用Logistic回归模型制作ROC曲线,并且计算曲线下面积(AUC)以评价各项指标的诊断价值。结果两组年龄、性别比较,差异无统计学意义(P>0.05);IBD组的3项检测项目水平大于健康对照组,差异均有统计学意义(Z=-13.746^-2.416,P<0.05)。各ROC曲线下最佳cut off值:RDW为13.15、NLR为2.90、PLR为167.5;各ROC曲线下的面积:RDW为0.561、NLR为0.845、PLR为0.749,联合检测为0.862;联合检测的约登指数高,敏感度达到69.2%。结论血液RDW、NLR和PLR在IBD患者中增高,3项指标可以作为评价IBD的标志物。
