From the Guidelines
The most recent and effective treatment for Primary Sclerosing Cholangitis (PSC) includes the use of ursodeoxycholic acid (UDCA) at doses of 15-20 mg/kg/d, which may improve serum liver tests and surrogate markers of prognosis, as recommended by the EASL clinical practice guidelines on sclerosing cholangitis 1. The treatment of PSC is evolving, and several therapies are being investigated for their potential benefits. Some key points to consider in the management of PSC include:
- The use of UDCA, which has been shown to improve liver biochemistry and may have a positive impact on prognosis, although the evidence is not yet conclusive 1.
- Endoscopic interventions, such as balloon dilation and stenting, are crucial for managing dominant strictures and relieving biliary obstruction, with balloon dilation being preferred over stenting due to lower complication rates 1.
- Liver transplantation remains the definitive treatment for advanced disease, with 5-year survival rates exceeding 80%.
- Emerging treatments, such as norursodeoxycholic acid and vancomycin, are being investigated for their potential benefits in reducing alkaline phosphatase levels and anti-inflammatory effects, respectively.
- Symptom management is also an important aspect of PSC treatment, with cholestyramine and rifampin being effective options for treating pruritus.
In terms of specific treatment recommendations, the use of UDCA at doses of 15-20 mg/kg/d is recommended, as it may improve serum liver tests and surrogate markers of prognosis, although the evidence is not yet conclusive 1. Additionally, endoscopic balloon dilation is preferred over stenting for managing dominant strictures, due to lower complication rates 1. Liver transplantation should be considered for patients with advanced disease, and symptom management should be tailored to the individual patient's needs.

From the Research
Recent Advancements in Primary Sclerosing Cholangitis (PSC) Treatment
- The primary goals of PSC treatment are to prevent disease progression, reduce symptoms, and prevent complications such as colorectal cancer and hepatobiliary cancer 2.
- Ursodeoxycholic acid (UDCA) is considered the most promising therapeutic option, as it improves biliary secretion and laboratory parameters of cholestasis 2, 3, 4.
- High-dose UDCA has been shown to improve liver chemistries and histology in some studies, but its effect on clinically relevant endpoints is still unclear 5, 4.
- Endoscopic treatment of dominant stenoses has been shown to improve cholestasis and prolong survival in patients with PSC 2, 3, 5.
- Immunosuppressive treatment has not been proven to be effective and may be harmful in certain cases, such as bacterial cholangitis 2.
- Liver transplantation remains the only therapeutic option for patients with advanced disease 2, 5.
Treatment Options
- UDCA is recommended as a first-line treatment for PSC, with high-dose UDCA showing a trend towards increased survival 5, 4.
- Endoscopic dilation of major duct stenoses is recommended for patients with dominant stenoses 3, 5.
- Cholestyramine is recommended as a first-line treatment for pruritus, with opioid antagonists, rifampin, or ondansetron as alternative options 2.
- Calcium and vitamin D supplementation are recommended for treatment of osteoporosis and osteopenia, with bisphosphonates as an option in selected cases 2.
Ongoing Research and Controversies
- The efficacy of UDCA in PSC is still a topic of debate, with some studies showing improvement in liver chemistries and histology, but not in clinically relevant endpoints 6.
- High-dose UDCA has been associated with increased mortality in one large randomized trial, highlighting the need for further research 6.
- The diagnosis and treatment of cholangiocarcinoma in PSC patients remains a challenge, with early diagnosis being a prerequisite for successful treatment 5.
