Background: The quantity and quality of skeletal muscle have been observed to be closely related with post-transplantation mortality in patients undergoing living donor liver transplantation (LDLT). However, the effect of LDLT on skeletal muscle has not been thoroughly investigated. The aim of this study was to investigate the change of trunk muscle mass and adiposity in recipients of LDLT. Methods: The study population included LDLT recipients at Hokkaido University Hospital who underwent pre- and post-operative computed tomography (CT) scans (31 recipients; 14 males, and 17 females)...

Molecular mechanisms of liver pathology and clinical disease in HEV infection remain unclear. MicroRNAs are known to modulate viral pathogenesis either by directly altering viral gene expression or by enhancing cellular antiviral responses. Given the importance of microRNA-122 (miR-122) in liver pathobiology, we investigated possible role of miR-122 in HEV infection. In silico predictions using genotype 1, 2, 3 and 4 HEV sequences showed that majority of genomes (203/222) harbor at least one miR-122/miR-122* target site...

BACKGROUND: Mistaken ingestion of all manner of toxic matter is common in childhood, but poisoning with fireworks and matchsticks is rare. Fireworks usually contain 10% yellow phosphorus and 50% potassium chlorate. Potassium chlorate is an extremely reactive and toxic agent that is used in fireworks and matchstick heads. METHODS: Eleven cases (7 females and 5 males; median age, 36 months [ranging from 24 to 48 months]) of poisoning after ingestion of fireworks and matchstick(s), between February 2008 and June 2014, were reviewed...

Donor safety is the major concern in living donor liver transplantation, although hepatic resection may be associated with postoperative coagulopathy. Recently, the use of sugammadex has been gradually increased, but sugammadex is known to prolong prothrombin time (PT) and activated partial thromboplastin time (aPTT). We compared the postoperative coagulation profiles and outcomes of sugammadex versus pyridostigmine group in donors receiving living donor hepatectomy.Consecutive donor hepatectomy performed between September 2013 and August 2016 was retrospectively analyzed...

Purpose: Biliary atresia precedes liver cirrhosis and liver transplantation. Amniotic membrane (AM) promotes tissue regeneration, inhibits fibrosis, and reduces inflammation. Here, we test amniotic membrane potential as a therapeutic tool against cholestatic liver fibrosis. Methods: Three groups of rats were used: sham surgery (SS), bile duct ligature (BDL), and bile duct ligature plus human amniotic membrane (BDL + AM). After surgery, animals were sacrificed at different weeks...

Hepatic and renal energy status prior to transplantation correlates with graft survival. However, effects of brain death (BD) on organ-specific energy status are largely unknown. We studied metabolism, perfusion, oxygen consumption, and mitochondrial function in the liver and kidneys following BD. BD was induced in mechanically-ventilated rats, inflating an epidurally-placed Fogarty-catheter, with sham-operated rats as controls. A 9.4T-preclinical MRI system measured hourly oxygen availability (BOLD-related R2*) and perfusion (T1-weighted)...

BACKGROUND & AIMS: Treatment with direct-acting antiviral (DAA) agents can reduce model for end-stage liver disease and Child-Pugh-Turcotte (CPT) scores in patients with decompensated cirrhosis caused by hepatitis C virus (HCV). However, many of these patients still die or require liver transplantation. We collected data on baseline features of patients and aimed to develop a scoring system to predict response to DAA therapy. METHODS: We performed a retrospective analysis of data from 4 trials of the effects of sofosbuvir-based therapy in patients with HCV-associated decompensated cirrhosis (502 of CPT class B and 120 of CPT class C)...

BACKGROUND: Diagnosis of de novo immune hepatitis (dnIH) after liver transplantation relies on biopsy findings, with an abundance of plasma cells (PCs) in the inflammatory infiltrates a hallmark of the disease. Very little is known about what other types of immune cells exist in the infiltrates mainly located in the portal areas of the liver tissue. METHODS: We analyzed the composition of T cells, B cells, PCs, and macrophages in the liver biopsies of 12 patients with dnIH, 9 of them obtained at the time of diagnosis...

Hepatocellular carcinoma (HCC) is among the most common lethal cancers of the digestive system with poor prognosis rates and ineffective therapeutic options. Matrine, a traditional Chinese medicine found in the roots of sophora species, has been used in the clinical treatment of liver fibrosis, chronic hepatitis B and other diseases. We have synthesized a matrine derivatives named WM622 (C26H35ON3S2) with a significant inhibitory effect on transplanted tumors in vivo. The half inhibitory concentration (IC50) of WM622 is 34 µM, which is much lower than matrine...

Congenital membranous occlusion of the inferior vena cava (IVC) in pediatric liver recipients may present with outflow occlusion and if unrecognized, result in graft loss. Prompt evaluation of outflow obstruction in the setting of unexplained inflow compromise is paramount. We report a case of successful IVC reconstruction in a patient with recurrent hepatic artery thrombosis (HAT). A 2-year-old child with history of two liver transplantations developed fevers, ascites, and abdominal tenderness one month after her second liver transplant...

The rising prevalence of chronic liver disease, coupled with a permanent shortage of organs for liver transplantation, has sparked enormous interest in alternative treatment strategies. Previous protocols to generate hepatocyte-like cells (HLCs) via pancreas-to-liver transdifferentiation have utilised fetal bovine serum, introducing unknown variables and severely limiting study reproducibility. Therefore, the main goal of this study was to develop a protocol for transdifferentiation of pancreatic progenitor cells to HLCs in a chemically defined, serum-free culture medium...

BACKGROUND The prognosis of the patients of acute liver failure (ALF) with onset of hepatic coma is often dismal. ALF is a well-accepted indication for liver transplantation (LT) and has markedly improved the prognosis of these patients. However, its role in ALF patients with onset of hepatic coma has never been elucidated before. The aim of our study was to analyze the outcome in patients of ALF with hepatic coma who underwent LT. MATERIAL AND METHODS From January 2002 to December 2015, a total of 726 liver transplantations were done at China Medical University Hospital, Taiwan...

Autoimmune hepatitis occurs in genetically susceptible individuals as a result of loss of immunological tolerance to hepatic autoantigens that can be precipitated by environmental triggers. The clinical manifestation is usually insidious but can be also acute with liver failure. The diagnosis is made on the basis of antibody positivity, elevated immunoglobulin G levels and interface hepatitis on liver histology. Induction of remission is achieved with high-dose steroids in the majority of cases, and maintenance of remission with azathioprine...

We report the clinical case of 23-year-old patient with liver cirrhosis of unknown genesis, significant resistant ascites, and 2 episodes of bleeding from esophageal varices. Evaluation did not find any cause of liver disease, and the patient was placed on the transplant wait list due to subcompensated liver function (Model for End-Stage Liver Disease score of 16, Child-Pugh class B) and poorly controlled severe portal hypertension. After treatment with diuretics, largevolume paracentesis, antibiotics, and vasoconstrictors, hepatorenal syndrome and spontaneous bacterial peritonitis resolved and liver function improved significantly...
