Primary sclerosing cholangitis (PSC) is a progressive cholestatic liver disease for which specific medical therapy is not available. The goals of treatment are primarily early detection and management of complications. In this review, we discuss novel therapies under evaluation and provide the foundation for surveillance strategies.
Drugs under investigation include norursodeoxycholic acid, nuclear receptor agonists, anti-fibrotics, antibiotics, and anti-inflammatory drugs. Endoscopic therapy is indicated for symptomatic dominant strictures and in the work-up of malignancies. Recently, the use of stents was associated with an increased rate of complications compared to balloon dilatation; and long-term stenting should be avoided. Malignancies currently account for most of the PSC-related mortality. Many drugs are emerging for the treatment of PSC but liver transplantation is the only treatment modality shown to prolong survival. PSC recurrence occurs in up to 35% of transplanted allografts within a median of 5 years. Surveillance for hepatobiliary and colorectal malignancies is indicated.
原发性硬化性胆管炎(PSC)是一种进行性胆汁淤积性肝病,目前尚无特效药物治疗。治疗的主要目标是早期发现并处理并发症。在本综述中,我们讨论正在评估的新型疗法,并为监测策略提供依据。
正在研究的药物包括去氧熊胆酸、核受体激动剂、抗纤维化药物、抗生素和抗炎药。内镜治疗适用于有症状的主导管狭窄以及恶性肿瘤的检查。最近,与球囊扩张术相比,使用支架会增加并发症发生率;应避免长期使用支架。目前,恶性肿瘤是PSC相关死亡的主要原因。许多药物正在用于PSC的治疗,但肝移植是唯一被证明能延长生存期的治疗方式。在移植后的异体肝中,高达35%会在中位时间5年内出现PSC复发。需要对肝胆和结直肠恶性肿瘤进行监测。
