Liver transplantation for sclerosing cholangitis

Area of Science:

• Hepatology
• Transplantation immunology
• Gastroenterology

Background:

• Primary sclerosing cholangitis (PSC) is a chronic liver disease often requiring liver transplantation.
• PSC is associated with inflammatory bowel disease (IBD) and specific human leukocyte antigen (HLA) types.
• Outcomes and complications following liver transplantation for PSC are not fully elucidated.

Purpose of the Study:

• To review the clinical course and outcomes of patients undergoing liver transplantation for PSC.
• To identify risk factors for graft loss and patient mortality.
• To assess the incidence and impact of rejection and associated comorbidities.

Main Methods:

• Retrospective review of 37 patients who received 46 liver transplants for PSC.
• Analysis of patient and graft survival rates at 1, 2, and 5 years.
• Evaluation of factors including prior surgery, HLA typing, IBD, rejection episodes, and causes of death.

Main Results:

• Excellent patient and graft survival rates were observed: 5-year survival was 65.2% for PSC.
• Prior non-cholecystectomy surgery increased operative time and blood loss.
• Higher rates of severe rejection occurred in patients with IBD (70%) compared to those without (36.4%).
• Colon cancer was the most frequent cause of death (3/7 deaths) in PSC patients post-transplant.

Conclusions:

• Liver transplantation provides favorable survival for PSC patients.
• Rejection episodes are common, often severe, and steroid-refractory.
• Colon cancer surveillance is critical for PSC patients after liver transplantation due to its high mortality risk.
