摘要

目的:探讨吲哚菁绿15分钟滞留率(indocyanine green retention rate at 15 minutes,ICG-R15)与肝硬化患者常规肝功能指标、有效肝血流量(effective hepatic blood flow,EHBF)、肝纤维化指标及肝脏硬度之间的关系,初步评价ICG清除试验在肝硬化患者肝储备功能评估中的临床价值。方法纳入14例接受ICG清除试验的肝硬化患者,收集人口学资料、胆碱酯酶、白蛋白、总胆红素(TBil)、直接胆红素(DBil)、间接胆红素(IBil)、凝血酶原时间(PT)、凝血酶原活动度(PTA)、血清肝纤维化指标、肝脏硬度值(LSM)、脂肪衰减参数、ICG-R15及EHBF等资料。依据检测参考范围,将ICG-R15<10%定义为ICG清除功能正常,ICG-R15≥10%定义为ICG清除功能受损。采用Spearman秩相关分析评价ICG-R15与各指标的相关性,采用Mann-Whitney U检验比较两组连续变量;并在乙型肝炎病毒(HBV)相关肝硬化患者中进行敏感性分析。结果14例患者中男性8例(57.1%),中位年龄52.0(43.8,60.3)岁,HBV相关肝硬化11例(78.6%)。ICG-R15中位数为5.35%(2.45%,20.90%),4例(28.6%)ICG-R15≥10%;EHBF中位数为698(415,933)mL/min。ICG-R15与TBil(ρ=0.670,P=0.009)及DBil(ρ=0.669,P=0.009)呈正相关,与EHBF呈负相关(ρ=-0.653,P=0.011)。与ICG-R15<10%组相比,ICG-R15≥10%组TBil[25.4(21.2,36.7)μmol/L比16.75(14.53,20.25)μmol/L,P=0.036]、DBil[7.4(5.4,16.65)μmol/L比3.9(3.3,4.63)μmol/L,P=0.028]更高,EHBF[331(225,430)mL/min比832(664,1032)mL/min,P=0.014]更低。在11例HBV相关肝硬化患者中,ICG-R15仍与TBil(ρ=0.700,P=0.016)、DBil(ρ=0.724,P=0.012)呈正相关,与EHBF呈负相关(ρ=-0.745,P=0.008)。结论:肝硬化患者ICG-R15升高与胆红素水平升高及有效肝血流量下降相关,提示ICG清除试验可从动态清除和肝脏血流动力学角度为传统静态肝功能评估提供补充信息。鉴于本研究样本量较小,相关结果仍需在更大样本、前瞻性队列中验证。
