5、作为研究对象,根据第3腰椎层面骨骼肌质量指数(skeletal muscle index,SMI)分为肌肉减少症组(81例)和非肌肉减少症组(27例)。比较两组患者的临床特征,采用logistic回归分析、ROC曲线探讨SII及PNI对IBD患者发生肌肉减少症的预测价值。结果肌肉减少症组患者的PNI为46.549.34,SII为2397.804884.88,与非肌肉减少症组的50.134.70和1140.60954.0比较,差异均有显著性(P0.05)。Logistic回归分析显示,SII1297.74(OR=5.917,95%CI 1.7427.42)和PNI47.90(OR=3.25,95
6、%CI 1.1615.55)均为IBD患者发生肌肉减少症的独立危险因素。ROC曲线分析显示SII预测IBD患者发生肌肉减少症的最佳截断值为1207.19,敏感度和特异度分别为64.20%和77.80%(P=0.004);PNI预测IBD患者发生肌肉减少症的最佳截断值为48.48,敏感度和特异度分别为61.73%和77.78%(P=0.008)。结论SII及PNI与IBD患者发生肌肉减少症存在相关性,可用于预测IBD患者肌肉减少症的发生。关键词:全身免疫炎症指数;预后营养指数;炎症性肠病;肌肉减少症中图分类号:R574文献标识码:A文章编号:1008-1070(2023)05-0494-05do
