摘要 目的:探讨原发性胆汁性肝硬化(PBC)患者血清抗核胞膜糖蛋白210抗体(抗GP210抗体)的变化及其意义。方法:比较抗GP210抗体阳性组(n=32)及阴性组(n=32),持续阳性组(n=13)及转换组(n=8)患者临床表现及相关实验室指标,分析抗GP210抗体与PBC患者预后及肝脏损害程度的关系。结果:与阴性组相比,阳性组Mayo危险性评分、肝衰竭发生率较高;血清丙氨酸转氨酶、总胆红素、直接胆红素水平亦较高,而胆碱酯酶水平较低,以上各指标间差异均具有统计学意义(P<0.05)。随访期间,阳性组死亡率为37.5%(12/32),高于阴性组的12.5%(4/32),两组间差异具有统计学意义(P=0.041),经log-rank检验显示阳性组生存时间较阴性组短。抗GP210抗体由阳性转为阴性后,凝血酶原活动度随之升高;与转换组比较,持续阳性组肝衰竭的发生率有增高的趋势。结论:抗GP210抗体的检测有助于PBC的早期诊断,并且与PBC的预后有关,该抗体对PBC预后的影响与其持续的时间有关。
