With the increasing age of recipients undergoing orthotopic liver transplant (OLT), there is need for better risk stratification among them. Our study aims to identify predictors of poor outcome among OLT recipients ≥ 60 yr of age. All patients who underwent OLT at Cleveland Clinic from January 2004 to April 2010 were included. Baseline patient characteristics and post-OLT outcomes (mortality, graft failure, length of stay, and major post-OLT cardiovascular events) were obtained from prospectively collected institutional registry. Among patients ≥ 60 yr of age, multivariate regression modeling was performed to identify independent predictors of poor outcome. Of the 738 patients included, 223 (30.2%) were ≥ 60 yr. Hepatic encephalopathy, platelet counts < 45,000/μL, total serum bilirubin > 3.5 mg/dL, and serum albumin < 2.65 mg/dL independently predicted poor short-term outcomes. The presence of pre-OLT coronary artery disease and arrhythmia were independent predictors of poor long-term outcomes. Cardiac causes represented the second most common cause of mortality among the elderly cohort. Despite that, this carefully selected cohort of older OLT recipients had outcomes that were comparable with the younger recipients. Thus, our results show the need for better pre-OLT evaluation and optimization, and for closer post-OLT surveillance, of cardiovascular disease among the elderly.
随着接受原位肝移植(OLT)患者年龄的增加,需要对他们进行更好的风险分层。我们的研究旨在确定年龄≥60岁的OLT受者预后不良的预测因素。纳入了2004年1月至2010年4月在克利夫兰诊所接受OLT的所有患者。患者的基线特征和OLT后的结局(死亡率、移植物失败、住院时间和OLT后主要心血管事件)来自前瞻性收集的机构登记处。在年龄≥60岁的患者中,进行多变量回归建模以确定预后不良的独立预测因素。在纳入的738例患者中,223例(30.2%)年龄≥60岁。肝性脑病、血小板计数<45,000/μL、总血清胆红素>3.5mg/dL和血清白蛋白<2.65mg/dL独立预测短期预后不良。OLT前冠状动脉疾病和心律失常的存在是长期预后不良的独立预测因素。心脏原因是老年队列中第二常见的死亡原因。尽管如此,这一经过精心挑选的老年OLT受者队列的结局与年轻受者相当。因此,我们的结果表明,对于老年人,需要在OLT前进行更好的评估和优化,并在OLT后对心血管疾病进行更密切的监测。
