Primary sclerosing cholangitis (PSC) recurs in one-third of liver transplant (LT) patients in Brazil, primarily associated with longer post-LT time. Recurrence did not significantly impact graft loss or survival.

Area of Science:

Hepatology
Transplant Surgery
Gastroenterology

Background:

Primary sclerosing cholangitis (PSC) recurrence post-liver transplantation (LT) is a known complication.
Risk factors for recurrent PSC (rPSC) and de novo cholangiocarcinoma (CCA) in admixed populations require further investigation.

Purpose of the Study:

Assess the prevalence of rPSC in a Brazilian LT cohort.
Identify risk factors associated with rPSC.
Investigate the occurrence of de novo CCA in patients with rPSC.

Main Methods:

Retrospective review of patients undergoing LT for PSC from the Brazilian Cholestasis Study Group database.
Analysis of clinical and laboratory data for rPSC and de novo CCA occurrence.

Main Results:

rPSC was observed in 30% of patients after a median follow-up of 90 months.
Increased time after LT was the only factor associated with rPSC.
No significant associations found between rPSC and age, gender, IBD, MELD score, or rejection.
One case of de novo CCA developed 11 years post-LT in a patient with rPSC.

Conclusions:

One-third of PSC LT patients in Brazil experienced rPSC, linked to longer post-LT duration.
rPSC did not significantly increase the risk of graft loss or reduce posttransplant survival.
The occurrence of de novo CCA was rare in this cohort.
