Long-term Prognosis and Recurrence of Primary Sclerosing Cholangitis After Liver Transplantation: A Single-Center Experience.

ABSTRACT: Primary sclerosing cholangitis (PSC) is a progressive cholestatic liver disease, with liver transplantation being the sole life-saving treatment for end-stage PSC-related liver disease. However, recurrence of PSC after liver transplantation is a common complication, with the risk factors for recurrence being controversial.We conducted a retrospective chart review of 45 patients who had undergone liver transplantation for PSC at our institute. The risk factors for PSC recurrence and graft failure after liver transplantation were analyzed.The graft survival rates were 55.4% at 5 years and 32.8% at 10 years after liver transplantation for PSC. PSC recurrence was diagnosed in 16 (40%) of 40 patients, at a median 30 months (range, 9-70 months) after liver transplantation. The cumulative incidence rate of PSC recurrence was 24.5% at 3 years, 39.3% at 5 years, and 45.8% at 6 years. Among the 16 patients diagnosed with PSC recurrence, the graft survival rate was 56.3% at 5 years, and 21.9% at 10 years after the recurrence. Active inflammatory bowel disease after liver transplantation was identified as an independent risk factor for PSC recurrence. Age younger than 30 years at the time of PSC diagnosis and bacteremia were factors significantly associated with graft failure after liver transplantation on multivariate analysis.PSC frequently recurred and progressed to graft failure after liver transplantation for PSC. Maintaining an inactive status of inflammatory bowel disease might offer protection against PSC recurrence.

Project description:Background & aimsPrimary sclerosing cholangitis (PSC) is a rare progressive liver disease associated with inflammatory bowel disease (IBD). It is usually diagnosed in adults but can also present in children. Data on long-term outcomes of pediatric PSC are limited. Our aim was to study the natural history of pediatric PSC in Sweden.MethodsThis is a cohort study, including all children (<18 years), diagnosed with PSC between January 2000 and December 2015 at the Pediatric Liver Unit at Karolinska University Hospital, Stockholm. Patients were followed until liver transplantation, death or last date of follow-up (August 2021).ResultsWe identified 124 children with a median age of 14 (1.9-17.8) years at PSC diagnosis. Sixty percent were boys, 93% had IBD. Median follow-up time was 13 years (5.7-21.6). Overall event-free survival in the cohort was 91% (95% CI 0.84-0.95) at 5 years and 77% (95% CI 0.68-0.84) at 10 years after diagnosis. Autoimmune hepatitis (AIH) was present in 31% (n = 39). Portal hypertension developed in 13% (n = 16), biliary complications in 24% (n = 30), cholangiocarcinoma (CCA) in 0.8% (n = 1), while 13% (n = 16) underwent liver transplantation and three patients died. Transplant-free survival was 91% after 10 years. Individuals with a high SCOPE index at diagnosis had a 2.3-fold increased risk of requiring liver transplantation (hazard ratio 2.35, 95% CI 1.18-4.66, c-statistics = 0.70). Patients with an additional diagnosis of autoimmune hepatitis had slightly higher risk of reaching transplantation during follow-up (hazard ratio 2.85, 95% CI 1.06-7.67, p = 0.038).ConclusionsChildren diagnosed with PSC have a good prognosis during the first decade after diagnosis. A high SCOPE index at diagnosis was associated with a less favorable outcome.Impact and implicationsData on long-term outcome in pediatric primary sclerosing cholangitis bridging over to adulthood is limited. There is a great need among children with primary sclerosing cholangitis and their parents for more knowledge about the natural history of this disease and what they can expect from the future. We hope that the data presented in this study may help counsel health professionals, young individuals and families affected by this disease.

Project description:Background & aimsPrimary sclerosing cholangitis (PSC) is a rare cholangiopathy of unknown aetiopathogenesis. The aim of this study was to evaluate cellular senescence (CS) marker expression in cholangiocytes of patients with PSC and their correlation with clinical-pathological features and prognosis.MethodsThirty-five patients with PSC with at least 1 available liver sampling were included. Clinical laboratory data at the time of liver sampling were collected. The endpoints were survival without liver transplantation (LT), time to LT, and survival without LT or cirrhosis decompensation. Histological grading and staging were assessed according to Nakanuma. Immunohistochemical stains for CS markers, p16INK4A (p16) and p21WAF1/Cip1 (p21), were performed and scored by a 3-tier scale based on positivity extent in native bile duct (NBD) and ductular reaction (DR).Results: p16 expression in NBD and DR was directly correlated with fibrosis (p ≤0.001 for both) and stage (p = 0.006 and p <0.001, respectively). Moreover, p16 in NBD was positively correlated with hepatitis activity (HA) (p = 0.026), whereas p16 in DR was directly correlated with bile duct loss (BDL) (p = 0.005) and metaplastic hepatocytes (MH) (p <0.01). p21 expression in NBD and DR was directly correlated with HA (p = 0.004 and p = 0.043, respectively), fibrosis (p = 0.006 and p <0.001, respectively), stage (p = 0.006 and p = 0.001, respectively), BDL (p = 0.002 and p = 0.03, respectively), and DR and MH (p ≤0.004 for all). By multivariate analysis, p16 expression in DR was independently associated with stage (p = 0.001), fibrosis (p = 0.001), and BDL (p = 0.011). p21 expression in NBD was independently associated with HA (p = 0.012), BDL (p = 0.04), and DR (p = 0.014). Finally, p21 expression in DR was independently associated with LT-free survival, time to LT, and adverse outcome-free survival (p = 0.001, p = 0.017, and p = 0.001, respectively).ConclusionsCholangiocyte senescence is detectable in all stages of PSC and is associated with histological and clinical disease severity, potentially representing a new prognostic and therapeutic target.Lay summaryIn this study, we showed that cholangiocyte senescence (CS), previously demonstrated in liver of patients with end-stage primary sclerosing cholangitis (PSC), is an early event and is detectable in all disease stages. Moreover, we observed that CS is associated with histological and clinical disease severity and patients' outcome. Thus, we suggest that CS may represent a new prognostic tool and a potential therapeutic target in PSC.Clinical trial numberProtocol number 0034435, 08/06/2020.
