INTRODUCTION: Hepatic morphology changes are well described in Primary Sclerosing Cholangitis and characterised by a combination of atrophy and hypertrophy changes. This study investigates the relationship between progression of these changes over time and clinical outcome in patients with PSC. METHODS: Fifty-three patients with PSC (mean age 44, 28 males and 25 females) who underwent serial MRI liver studies at least one year apart were identified. The first and the last MRI studies were selected for the retrospective analysis...

The long-term survival in liver transplant recipients (LTRs) is currently at an historical high level stemming from improvement in perioperative care, infection control, and immunosuppression medications. However, compared to the general population, LTRs have decreased survival. Metabolic diseases like hypertension, dyslipidemia, type 2 diabetes, and obesity are key determinants of long-term mortality in LTRs. The incidence and prevalence of these metabolic comorbidities is considerably higher in LTRs and likely results from a combination of factors including exposure to chronic immunosuppression, weight gain, and recurrence of chronic liver disease after liver transplantation (LT)...

Major concerns about donor safety cause controversy and limit the use of living donor liver transplantation to overcome organ shortages. The Korean Organ Transplantation Registry established a nationwide organ transplantation registration system in 2014. We reviewed the prospectively collected data of all 832 live liver donors who underwent procedures between April 2014 and December 2015. We allocated the donors to a left lobe group (n=59) and a right lobe group (n=773) and analyzed the relations between graft types and remaining liver volumes and complications (graded using the Clavien five-tier grading system)...

Portal vein thrombosis occurs in 1.4% of pediatric liver transplant candidates and 3.7% of liver transplant recipients. While portal vein recanalization without and with portal vein stenting has been described in adult transplant candidates and recipients, it has never been described in the pediatric transplant population. This report presents a pediatric liver transplant recipient with portal hypertension secondary to portal vein thrombosis successfully managed with transsplenic access and subsequent portal vein recanalization and stenting...

AIM: To develop a locally adapted, patient-focused transition-program, we evaluated the perceptions of adult and adolescent patients and parents regarding transition-programs and transfer. METHODS: We evaluated these perceptions by analyzing the responses of pre-transfer adolescents (n = 57), their parents (n = 57) and post-transfer adults (n = 138) from a cohort of pediatric-liver-transplant-patients using a self-designed questionnaire. Furthermore, we compared a responder group with a non-responder group as well as the provided answers with baseline characteristics and clinical outcomes to exclude selection bias, characterize high-risk patients for non-adherence and test for gender differences...

OBJECTIVE: Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of IBD. This clinical association is linked pathologically to the recruitment of mucosal T cells to the liver, via vascular adhesion protein (VAP)-1-dependent enzyme activity. Our aim was to examine the expression, function and enzymatic activation of the ectoenzyme VAP-1 in patients with PSC. DESIGN: We examined VAP-1 expression in patients with PSC, correlated levels with clinical characteristics and determined the functional consequences of enzyme activation by specific enzyme substrates on hepatic endothelium...

Tracking the distribution and degradation of hydrogels in vivo is important for various applications including tissue engineering and drug delivery. Among various imaging modalities, fluorescence imaging has attracted intensive attention due to their high sensitivity, low cost and easy operation. Particularly, upconversion nanoparticles (UCNPs) that emit visible lights upon near-infrared (NIR) light excitation as tracking probes are promising in deciphering the fate of hydrogels after transplantation. Herein, we reported a facile and non-invasive in vivo hydrogel tracking method using UCNPs, where the degradation of hydrogels was determined using the decrease in fluorescence intensity from the UCNPs encapsulated in the hydrogels...

BACKGROUND: Postoperative acute lung injury(ALI) is a severe complication after liver transplantation, which severely affects postoperative patients' survival. The underlying mechanism is largely unknown and effective treatment limited. We explored the role of serpin protease inhibitor B1(SERPINB1), a potent inhibitor of neutrophil serine proteases, in ALI in liver transplantation and its interplay with signal transducer and activator of transcription 3(STAT3) and heme oxygenase-1(HO-1)...

REVIEW
Aydin Seref Koksal, Ahmet Tarik Eminler, Erkan Parlak, Ahmet Gurakar
Biliary strictures constitute 40% to 60% of the biliary complications after liver transplantation. They are more common after living donor related liver transplantation (LDLT) than orthotopic liver transplantation (OLT). Balloon dilation followed by multiple plastic stent insertion leads to a mean resolution rate of 84% in the treatment of ASs after OLT. Endoscopic treatment of ASs after LDLT is more difficult because of the small size of the ASs, their multiple number and peripheral location. Balloon dilation followed by multiple plastic stent insertion had a mean resolution rate of 53%...

BACKGROUND: A considerable number of patients with portal hypertension (PHT) have to undergo splenectomy because they do not meet the requirements for liver transplantation (LT) or cannot find a suitable liver donor. However, it is not known whether pre-transplantation splenectomy may create occult difficulties for patients who require LT in future. METHODS: We analyzed 1059 consecutive patients who underwent adult liver transplantation (ADLT). Patients with pre-transplantation splenectomy Sp(+) and without splenectomy Sp(-) were compared using a propensity score analysis to create the best match between groups...

BACKGROUND: Chronic kidney disease is a significant complication after liver transplantation (LT), but the role of pre-existing renal insufficiency and proteinuria remains unclear among LT recipients receiving sirolimus. METHODS: We assessed the effects of proteinuria and baseline renal function on long-term renal and survival outcomes among 576 LT recipients who received SRL in a medical center between 2005 and 2014. Renal outcomes were the incidences of >50% reduction in their baseline estimated glomerular filtration rate and end stage kidney disease requiring renal replacement therapy...

BACKGROUND: Advanced stages of liver cirrhosis lead to a dramatically increased mortality. For valid identification of these patients suitable biomarkers are essential. The most important biomarkers for liver function are bilirubin and prothrombin time expressed as International Normalized Ratio (INR). However, the influence of several anticoagulants on the prothrombin time limits its diagnostic value. Aim of this study was the evaluation of cholesterol esterification (CE) fraction (esterified cholesterol vs...

RATIONALE: Hepatic steatosis develops after liver transplant in 30% of adults, and non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in non-transplanted children. However, post-transplant steatosis has been minimally studied in pediatric liver transplant recipients. We explored the prevalence, persistence, and association with chronic liver damage of hepatic steatosis in these children. RESULTS: In this single-center study of pediatric patients transplanted 1988-2015 (n=318), 31% of those with any post-transplant biopsy (n=271) had ≥1 biopsy with steatosis...

AIM: Hepatitis B virus-related acute-on-chronic liver failure has high short-term mortality. Artificial liver support systems (ALSS) may improve outcome and avoid liver transplantation, but predicting short-term prognosis in such patients is difficult. This study aimed to determine whether the neutrophil-lymphocyte ratio (NLR), an inflammation marker, predicted mortality in patients treated with ALSS. METHODS: A total of 560 patients with hepatitis B virus-related acute-on-chronic liver failure were enrolled, 338 were treated with ALSS and the others treated with standard of care(SOC)...

BACKGROUND: Liver grafts from donation after circulatory death (DCD) donors are increasingly accepted as an extension of the organ pool for transplantation. There is little data on the outcome of liver transplantation with DCD grafts from a pediatric donor. The objective of this study was to assess the outcome of liver transplantation with pediatric DCD grafts and to compare this with the outcome after transplantation of livers from pediatric donation after brain death (DBD) donors. METHOD: All transplantations performed with a liver from a pediatric donor (≤16 years) in the Netherlands between 2002 and 2015 were included...

BACKGROUND: Patients undergoing liver transplantation frequently but inconsistently require massive blood transfusion. The ability to predict massive transfusion (MT) could reduce the impact on blood bank resources through customization of the blood order schedule. Current predictive models of MT for blood product utilization during liver transplantation are not generally applicable to individual institutions owing to variability in patient population, intraoperative management, and definitions of MT...

PURPOSE OF REVIEW: Hepatic hydrothorax is a complication of end-stage liver disease that may have significant associated morbidity. Sodium restriction and diuretic therapy are the mainstays of treatment, though up to a quarter of patients will become refractory to this and will require a pleural drainage procedure. Thoracentesis, transjugular intrahepatic portosystemic shunt, and chemical pleurodesis all have variable success rates and associated complications in the management of hepatic hydrothorax...
