目的评价急性肝功能衰竭肝移植患者的近期及远期生存情况和分析影响移植疗效的相关因素。方法回顾性分析2001年1月至2004年12月在我院连续施行的318例肝移植资料(随访至2005年12月),根据UNOS肝功能分级标准,对受体的术前状态进行评估,其中包括54例急性肝功能衰竭(UNOS1和2A)和264例慢性肝病肝硬化(UNOS2B和3),并统计了术后并发症的发生率、再移植率、再移植原因和死亡原因。结果术前肝功能状态为UNOS2B和3的移植组,围手术期死亡率为3.7%,术后并发症发生率为16.7%,再移植率1.1%,其1、3年生存率分别为91.3%和86,4%。术前肝功能状态为UNOSl和2A的肝移植组,围手术期死亡率为22,6%,术后并发症发生率为55.6%,再移植率18.5%,其1、3年生存率分别为74,1%和68,5%。结论肝移植效果主要取决于肝外器官功能和术前肝功能状态,术前肝功能状态为UNOS2B和3的慢性肝病肝硬化患者肝移植后近期和远期疗效较好,而术前肝功能状态为UNOS1和2A的急性肝功能衰竭患者则围手术期死亡率较高。  相似文献

Congestive heart failure as a cause of acute liver failure is rarely documented with only a few cases.Although the pathophysiology is poorly understood, there is rising evidence, that low cardiac output with consecutive reduction in hepatic blood flow is a main causing factor, rather than hypotension. In the setting of acute liver failure due to congestive heart failure, clinical signs of the latter can be absent, which requires an appropriate diagnostic approach.As a reference center for acute liver failure and liver transplantation we recorded from May 2003 to December 2007 202 admissions with the primary diagnoses acute liver failure. 13/202 was due to congestive heart failure, which was associated with a mortality rate of 54%. Leading cause of death was the underlying heart failure. Asparagine transaminase (AST), bilirubin, and international normalized ratio (INR) did not differ significantly in surviving and deceased patients at admission. Despite both groups had signs of cardiogenic shock, the cardiac index (CI) was significantly higher in the survival group on admission as compared with non-survivors (2.1 L/min/m2 vs. 1.6 L/min/m2, p = 0.04). Central venous - and pulmonary wedge pressure did not differ significantly. Remarkable improvement of liver function was recorded in the group, who recovered from cardiogenic shock.In conclusion, patients with acute liver failure require an appropriate diagnostic approach. Congestive heart failure should always be considered as a possible cause of acute liver failure.  相似文献

生物人工肝是治疗肝功能衰竭的有效方法。肝细胞是生物人工肝系统的核心,生物人工肝的肝支持作用完全依赖于所用肝细胞的特异性生物学功能。生物人工肝中使用的肝细胞来源主要有人源性肝细胞、异种肝细胞、肝细胞株等。近20年来,虽然对各种来源的肝细胞进行了广泛和深入研究,但是生物人工肝细胞材料的来源问题至今未能得到满意解决。文章综述此方面的最新研究进展。  相似文献

Objective: Hepatic progenitor cell transplantation has shed light on the treatment of liver failure. The present study was designed to evaluate whether xenogeneic liver epithelial progenitor cells (LEPCs) transplantation could promote liver recovery in a rat model of acute liver failure. The engraftment and hepatocytic differentiation of transplanted hepatic progenitor cells in the rat spleen was also investigated. Methods: LEPCs were propagated in vitro for long and transduced with lentiviral vector carrying mCherry gene. Intraperitoneal injection of CC14 followed by 2/3 partial hepatectomy three days later were used to establish rat models of acute liver failure. Rats were intrasplenically injected with mCherry modified LEPCs (n=20, 1× 107 cells/0.5 mL) or the same volume of medium (n=20). Serum liver enzymes (ALT, AST) and liver histology were evaluated for 21 days after transplantation. The engraftment of transplanted LEPCs in the spleens was tested by polymerase chain reaction (PCR) amplification targeting mCherry gene. The differentiation into hepatocytic lineage of transplanted LEPCs was investigated usingimmunohistochemistry staining against Alb. Results: LEPCs were effectively transduced with lentiviral vector showing a transduction efficiency of 90%. Compared with control, cell-injected group displayed significantly lower levels of ALT and AST (P〈0.05) and better histological features including less swelling change and hepatocyte death. PCR amplification of mCherry sequences confirmed the engraftment of LEPCs in the spleens. Alb-positive cells first appeared 5 days after cell transplantation and the number of Alb-positive cells increased substantially (P〈0.05), which revealed the hepatocytic differentiation process Conclusion: Xenogeneic hepatic progenitor cells can engraft and differentiate into hepatocytes in the splenic parenchyma. Intrasplenic delivery of hepatic progenitor cells ameliorates CCh/partial hepatectomy-induced liver injury in rats  相似文献

Background Because of the lack of brain death laws in China, the proportion of cadaveric organ donation is low. Many patients with end-stage liver disease die waiting for a suitable donor. Living donor liver transplantation (LDLT) would reduce the current discrepancy between the number of patients on the transplant waiting list and the number of available organ donors. We describe the early experience of LDLT in the mainland of China based on data from five liver transplant centers. Methods Between January 2001 and October 2003, 45 patients with end-stage liver disease received LDLT at five centers in China. The indication and timing, surgical techniques and complications, nonsurgical issues including rejection, infection, and advantages of LDLT in the series were reviewed. Actuarial patient and graft survival rates were calculated by using the Kaplan-Meier product-limit estimate. Statistical analysis was completed by using SPSS 10.0. Results All LDLT recipients were cirrhotic patients, except for one man with fulminant hepatic failure. Among the 45 cases of LDLT, 35 (77.8%) were performed in one center (the First Affiliated Hospital of Nanjing Medical University). The overall 1 and 3 year survival rate of the recipients was 93.1% and 92.0%, respectively. Of the 45 LDLT donors, there were 3 cases of biliary leakage, 2 subphrenic collections, 1 fat liquefaction around the incision and 1 biliary peritonitis after T tube removal. All donors recovered completely. Conclusions LDLT provides an excellent approach to addressing the problem of donor shortage in China even though the operation is complicated, uncompromising and difficult with respect to the safety of the donors and receptors. Despite early technical hurdles having been overcome, perfection of technique is still necessarily. At present, LDLT is a good choice for the patients with irreversible liver disease.  相似文献

目的:探讨导致原位肝移植术后重症监护病房(ICU)真菌感染的病原学特征和临床高危因素.方法:回顾我院2000-11/2006-01施行的102例次原位肝移植临床资料,对可能导致术后真菌感染的围手术期相关因素进行分析,筛选临床高危因素.结果:肝移植术后平均ICU留住时间为11.0d(7~23d),其间真菌感染的发病率为16%(16/102),平均发病时间为术后11.8d(6~18d).主要致病菌为白色念珠菌,约占75%,发生部位以肺部(73%)和血液(19%)多见.多因素Logistic回归分析显示术前UNOS评分、术后中心静脉导管留置时间以及术后细菌、病毒等其他感染是诱发肝移植术后受体真菌感染的高危因素.结论:真菌感染是发生于肝移植术后ICU内重要并发症.白色念珠菌是最常见的致病菌.针对以上高危因素及早采取合理、有效的防治措施是减少ICU真菌感染的关键.  相似文献
