AJG:血清转铁蛋白是酒精性肝炎死亡的预测因子

2020-02-22 不详 MedSci原创

严重的酒精性肝炎(sAH)可导致死亡,但该病的病程难以预测。由于铁参数是其他肝脏疾病中有吸引力的预后指标,因此本项研究探究了它们在sAH中的预后能力。

目标:
严重的酒精性肝炎(sAH)可导致死亡,但该病的病程难以预测。由于铁参数是其他肝脏疾病中有吸引力的预后指标,因此本项研究探究了它们在sAH中的预后能力。

方法:
在STOPAH试验中,研究人员对828名sAH患者进行了血清铁蛋白,转铁蛋白,铁,转铁蛋白饱和度,非转铁蛋白结合铁,可溶性转铁蛋白受体和铁调素的测定。将该队列随机分为探索性(n = 200)和验证集(n = 628)2列。

结果:
sAH患者的血清转铁蛋白减少,但转铁蛋白饱和度增加。在铁参数中,基线转铁蛋白是28天(AUC为0.72 [95%置信区间0.67-0.78])和90天存活率(AUC为0.65 [0.61-0.70])的最佳预测指标。转铁蛋白的预测能力与综合评分相当,即终末期肝病模型,格拉斯哥酒精性肝炎评分和判别功能,并且在多变量分析中与生存率独立相关。在验证队列中证实了这些结果。转铁蛋白与肝脏合成标志物,与未与转铁蛋白结合的铁或可溶性转铁蛋白受体和功能性铁缺乏的标志,

讨论:
在sAH患者中,血清转铁蛋白可预测死亡率,其性能可与常用的复合评分系统相媲美。
