BACKGROUND: Although they are expandable in vitro, hepatic progenitors are immature cells and share many immunomarkers with hepatocellular carcinoma, raising potential concerns regarding maltransformation after transplantation. This study investigated the effects of hepatic nuclear factor (HNF) 4α on the proliferation, migration, and maltransformation of hepatic progenitors and determined the feasibility of using these manipulated cells for transplantation. METHODS: The effects of HNF4α on rat hepatic progenitors (i...

In mammals, hematopoietic stem and progenitor cells (HSPCs) rapidly expand in the fetal liver (FL), but the underlying mechanism remains unclear. Here, we characterize zebrafish caudal hematopoietic tissue (CHT) and identify an important cellular and molecular mechanism of HSPC expansion. Time-lapse imaging showed that HSPCs localize adjacent to vascular endothelial cells (ECs), and their migration and expansion display caudal vein-specific orientation in the CHT. RNA sequencing and functional analysis identified that an EC-expressed transcription factor, Krüppel-like factor 6a (Klf6a), is essential for the CHT niche...

BACKGROUND: End-stage liver disease (ESLD) is the most common cause of secondary immunoglobulin A nephropathy (IgAN). Multiple mechanisms have been proposed to explain the association between liver disease and IgAN. Although some mechanisms are expected to reverse in patients after liver transplant, the long-term renal prognosis is unclear for these patients. METHODS: This observational retrospective cohort study examined the renal outcomes of 14 patients who had IgAN with end-stage liver disease and subsequently underwent either liver transplant alone or combined liver and kidney transplant at a single tertiary care center...

BACKGROUND: The cytoprotective effects of hemeoxygenase-1 and its product biliverdin/bilirubin are widely acknowledged in experimental transplant medicine. However, its potentially beneficial effect during organ reperfusion is not established. METHODS: In a matched study, we compared markers of reperfusion injury (alanine aminotransferase/aspartate aminotransferase) and transplantation outcome (complication rates, liver function, and survival) between recipient groups with "normal" versus "increased" preoperative bilirubin values...

Lung transplantation is a viable treatment option for patients with end-stage lung diseases such as interstitial pneumonia/pulmonary fibrosis, emphysema, pulmonary hypertension, and so on. Collecting available clinical, physiological, serological, and surgical information of both donor and recipient is vital when planning relevant postoperative managements. The goal of the managements is to keep the transplanted lung (s) functional while preventing/treating infection, rejection, and ischemiareperfusion lung injury...

BACKGROUND: Duration of functional warm ischemia (f-WIT) is thought to have a causal effect on outcomes in controlled donation after circulatory death (DCD) liver transplantation (LT). METHODS: A retrospective cohort study was conducted at five centers. Data were extracted on donor and recipient characteristics, with attention to parameters recorded during withdrawal of life support to in-situ cold perfusion. F-WIT was the time elapsed from any of the hemodynamic and oxygenation parameters to the start of in-situ cold perfusion...

Orthotopic liver transplantation (OLT) represents a curative treatment option for end-stage liver disease (ESLD). While epidemiology of ESLD has recently changed due the rising prevalence of non-alcoholic fatty liver disease (NAFLD) and decreased burden of hepatitis C virus (HCV) infections due to highly-effective antiviral regimens, the management of portal hypertension (PHT) remains a clinical challenge in the pre- and post-OLT setting. The measurement of hepatic venous pressure gradient (HVPG) represents the most reliable, but invasive tool for assessment of the severity of PHT...

BACKGROUND Rituximab is commonly used to reduce the agglutinin titer in ABO-incompatible liver transplant recipients. Although well-tolerated, rituximab infusion therapy may result in severe pulmonary adverse effects such as drug-induced pneumonitis, leading to acute respiratory distress syndrome (ARDS), which has a high mortality rate. Management of such rare cases in an ABO-incompatible patient has never been described before. Herein, we present successful use of extracorporeal membrane oxygenation (ECMO) support for rituximab-induced ARDS in an ABO-incompatible living donor liver transplantation (LDLT) recipient...

To explore the effects of propofol post-conditioning (PPC) on hepatic ischaemia/reperfusion injury (HIRI) and the potential mechanisms that might be involved in the interaction of Brahma-related gene1(BRG1) and Nuclear-related factor 2(Nrf2). Patients were randomized into PPC(n = 16) and non-PPC(NPC)( n = 21) groups. Propofol(2 mg/kg) was infused within 10 min. of the onset of liver reperfusion during liver transplantation in the PPC group. Liver function tests, as well as Brg1, Nrf2, Heme oxygenase-1(HO-1) and NADPH:quinone oxidoreductase1(NQO1) expression levels were evaluated...

Cytomegalovirus (CMV) is one of the most frequently encountered opportunistic viral pathogens in kidney transplant recipients. In this study, we retrospectively reviewed all living related and unrelated kidney transplant recipients on regular follow-up from January 2006 to June 2015, who were suspected to have CMV clinically and confirmed by DNA polymerase chain reaction (PCR). CMV PCR was detected in 102 kidney transplant recipients. The median time of detection after kidney transplant was 21 months, ranging from 15 days to 84 months...

BACKGROUND: Although the hemodynamic benefits of venovenous bypass (VVB) during liver transplantation (LT) are well appreciated, the impact of VVB on posttransplant renal function is uncertain. The aim of this study was to determine if VVB was associated with a lower incidence of posttransplant acute kidney injury (AKI). METHODS: Medical records of adult (≥18 years) patients who underwent primary LT between 2004 and 2014 at a tertiary hospital were reviewed. Patients who required pretransplant renal replacement therapy and intraoperative piggyback technique were excluded...
