摘要
目的 肝豆状核变性（又称Wilson病，WD）是由ATP7B基因突变引起的铜代谢紊乱疾病，常累及肝脏和中枢神经系统，严重者可致死。目前关于WD患者死亡原因及危险因素的系统研究较少。本研究旨在探讨WD患者的常见死亡原因及其危险因素。方法 回顾性分析2011年1月—2022年1月间安徽中医药大学神经病学研究所附属医院87例死亡WD患者和113例存活WD患者的临床资料，分析死亡原因，并通过Cox回归分析死亡危险因素。结果 死亡组年龄中位数为32.00（27.00，41.00）岁、病程中位数为144.00（72.00，228.00）个月，存活组年龄中位数为31.00（25.00，37.00）岁、病程中位数为132.00（72.00，214.00）个月。主要死亡原因包括肝衰竭（33例）、感染（23例）、猝死（8例）、消化道出血（8例）及肝癌（4例）等。死亡组与存活组在性别、起病形式、低铜饮食、肝脏B超分型、脾脏切除、临床分型、治疗方案及多项实验室指标（如白细胞计数、TB、Alb等）上差异有统计学意义（P<0.05）。多因素Cox回归显示，基线尿铜每增加100 μg/24 h（HR=1.22， 95%CI 1.11~1.34）与肝硬化（HR=2.55，95%CI 1.02~6.36）使死亡风险增加。结论 WD患者的主要死亡原因为肝衰竭，高水平基线尿铜和肝硬化显著增加死亡风险。尿铜水平达400 μg/24 h（参考值<100 μg/24 h）的患者死亡风险较基线增加3.8倍（HR=3.8，P<0.001）。研究结果为WD患者的预后评估和临床干预提供了重要依据。
Abstract
Objective Hepatolenticular degeneration（also know as Wilson disease ，WD） is a copper metabolic disorder caused by ATP7B gene mutation， often involving the liver and the central nervous system and leading to death in severe cases. At present， there is a lack of systematic studies on the cause of death and related risk factors in WD patients. Therefore， this study aims to investigate the common causes of death and related risk factors in WD patients. Methods A retrospective analysis was performed for the clinical data of 87 WD patients who died and 113 WD patients who survived in our hospital from January 2011 to January 2022. The common causes of death in WD patients were analyzed， and the Cox proportional-hazards regression model analysis was used to investigate the risk factors for death. Results The death group had a median age of 32.00 （27.00，41.00） years and a median course of disease of 144.00 （72.00，228.00） months， and the survival group had a median age of 31.00 （25.00，37.00） years and a median course of disease of 132.00 （72.00，214.00） months. The main causes of death included liver failure （33 patients）， infection （23 patients）， sudden death （8 patients）， gastrointestinal bleeding （8 patients）， and liver cancer （4 patients）. There were significant differences between the death group and the survival group in sex， pattern of disease onset， low copper diet， liver ultrasound classification， splenectomy， clinical classification， treatment regimens， and various laboratory markers （such as white blood cell count， total bilirubin， and albumin）（P<0.05）. The multivariate Cox regression analysis showed that the risk of death was doubled for every 100 μg/24 h increase in urinary copper at baseline （HR=1.22，95%CI 1.11-1.34） and the presence of liver cirrhosis （HR=2.55，95%CI 1.02-6.36）. Conclusion Liver failure is the main cause of death in WD patients， and a high level of urinary copper at baseline and the presence of liver cirrhosis significantly increase the risk of death. The risk of death in patients with a urinary copper level of 400 μg/24 h （reference value<100 μg/24 h） was increased by 3.8 times compared with the value at baseline （HR=3.8，P<0.001）.The results of this study provide an important basis for the prognosis evaluation and clinical intervention of WD patients.
