Primary biliary cirrhosis (PBC) is an immune-mediated chronic progressive inflammatory liver disease, predominantly affecting middle-aged women, characterized by the presence of antimitochondrial antibodies (AMAs), which can lead to liver failure. Genetic contributions, environmental factors including chemical and infectious xenobiotics, autoimmunity and loss of tolerance have been aggressively investigated in the pathogenesis of PBC, however, the actual impact of these factors is still controversial. Survival of PBC patients has been largely improved with the widespread use of ursodeoxycholic acid (UDCA), however, one third of patients still do not respond to the treatment and proceed to liver cirrhosis, requiring liver transplantation as a last resort for cure. The outcome of liver transplantation is excellent with 5- and 10-year survival rates around 80% and 70%, respectively, while along with long survival, the recurrence of the disease has become an important outcome after liver transplantation. Prevalence rates of recurrent PBC rage widely between 1% and 35%, and seem to increase with longer follow-up. Center-specific issues, especially the use of protocol biopsy, affect the variety of incidence, yet, recurrence itself does not affect patient and graft survival at present, and retransplantation due to recurrent disease is extremely rare. With a longer follow-up, recurrent disease could have an impact on patient and graft survival.
原发性胆汁性肝硬化(PBC)是一种免疫介导的慢性进行性炎症性肝病,主要影响中年女性,其特征是存在抗线粒体抗体(AMA),可导致肝衰竭。在PBC的发病机制中,人们对遗传因素、包括化学和感染性外来生物在内的环境因素、自身免疫和耐受性丧失进行了深入研究,然而,这些因素的实际影响仍存在争议。随着熊去氧胆酸(UDCA)的广泛应用,PBC患者的生存率有了很大提高,然而,仍有三分之一的患者对治疗无反应并发展为肝硬化,最终需要肝移植作为最后的治疗手段。肝移植的效果很好,5年和10年生存率分别约为80%和70%,然而,随着长期存活,疾病复发已成为肝移植后的一个重要问题。复发性PBC的患病率在1%至35%之间广泛波动,且似乎随着随访时间的延长而增加。特定中心的问题,尤其是方案活检的使用,影响了发病率的差异,然而,目前复发本身并不影响患者和移植物的存活,因复发疾病而再次移植极为罕见。随着随访时间的延长,复发疾病可能会对患者和移植物的存活产生影响。
