Hepatic Encephalopathy (HE) is a complex neuropsychiatric syndrome associated with decompensated liver disease. The spectrum of disease ranges from trivial abnormalities in complex decision making and prolonged reaction time to coma in its most severe form1. The very initial stages, recently termed covert Hepatic Encephalopathy (CHE), can only be diagnosed with the help of neuropsychiatric testing while the later and more severe forms, termed overt Hepatic Encephalopathy (OHE), can be diagnosed clinically. Severity of HE is graded based on West Haven Criteria and please refer to table 1 for more details2...

NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency...

Arginase-1 (Arg1) converts arginine to urea and ornithine in the distal step of the urea cycle in liver. We previously generated a tamoxifen-inducible Arg1 deficient mouse model (Arg1-Cre) that disrupts Arg1 expression throughout the whole body and leads to lethality ≈ 2 weeks after gene disruption. Here, we evaluate if liver-selective Arg1 loss is sufficient to recapitulate the phenotype observed in global Arg1 knockout mice, as well as to gauge the effectiveness of gene delivery or hepatocyte transplantation to rescue the phenotype...

PURPOSE OF REVIEW: Although the liver possesses a unique, innate ability to regenerate through mass compensation, transplantation remains the only therapy when damage outpaces regeneration, or liver metabolic capacity is irreversibly impacted. Recent insight from developmental biology has greatly influenced the advancement of alternative options to transplantation in these settings. RECENT FINDINGS: Factors known to direct liver cell specification, expansion, and differentiation have been used to generate hepatocyte-like cells from stem and somatic cells for developing cell therapies...

PURPOSE OF REVIEW: Hepatocellular carcinoma (HCC) is becoming an important cause of mortality in patients with HIV, attributed to coinfection with hepatitis C virus, hepatitis B virus, and the longer survival advantage these patients are achieving after introducing the highly active antiretroviral therapy (HAART) regimens. RECENT FINDINGS: In addition to hepatitis infection, immunosuppression secondary to HIV infection, direct impact of the virus on liver parenchyma, and the use of hepatotoxic antiretroviral drugs, all contribute to HCC pathogenesis...

Liver failure is a frequent and serious complication that causes morbidity and mortality in haematopoietic stem cell transplantation (HCT) recipients. Liver dysfunction in these patients can be related to infectious causes, most common viral hepatitis. We report a case of disseminated acyclovir-resistant herpes simplex virus (HSV) infection following HCT that led to acute liver failure and death. Although rare, HSV hepatitis leads to high morbidity and mortality and should be considered in the differential diagnosis of HCT recipients with marked elevation of hepatic transaminase...

BACKGROUND AND AIM: To assess the efficacy and safety of sofosbuvir-based interferon-free therapies in liver transplantation recipients with hepatitis C virus infection recurrence. METHODS: A systematic literature search was conducted in PubMed, EMBASE, Web of Science, and CENTRAL on the Cochrane Library without time or language limitation. The search strategy used was "sofosbuvir AND transplantation". Sustained virologic response at 12 weeks after the end of treatment (SVR12) rate, incidence of serious adverse events (SAEs) and/or adverse events (AEs), discontinuation rate with 95% confidence intervals (CI) were pooled with random-effects model...

Acute-on-chronic liver failure (ACLF) is a distinct entity that differs from acute liver failure and decompensated cirrhosis in timing, presence of treatable acute precipitant, and course of disease, with a potential for self-recovery. The core concept is acute deterioration of existing liver function in a patient of chronic liver disease with or without cirrhosis in response to an acute insult. The insult should be a hepatic one and presentation in the form of liver failure (jaundice, encephalopathy, coagulopathy, ascites) with or without extrahepatic organ failure in a defined time frame...

The progressively increasing rates of obesity have led to a worldwide epidemic of nonalcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome. It is currently the most common cause of liver disease worldwide and projected to be the leading indication for liver transplantation in the United States by 2020. NAFLD is associated with both liver-related and overall mortality. Undoubtedly, nutrition interventions are key in the treatment of NAFLD, to reverse the disease, and prevent disease progression, complications, and associated comorbidities, including cardiovascular disease and diabetes...

New direct-acting antivirals (DAAs) have dramatically improved sustained virologic response (SVR) rates in patients treated for chronic hepatitis C. Although the safety of these agents has been very good in registration trials, unexpected side effects have been reported after much broader use of DAAs on marketing. We retrospectively examined all liver transplant recipients with chronic hepatitis C that received sofosbuvir-based regimens at our clinic. A total of 24 liver transplant recipients with recurrent chronic hepatitis C had received sofosbuvir up to April 2015...

OBJECTIVE: The aim of this study was to determine whether a portal flow of <1,000 mL/min in orthotopic liver transplantation (OLT) is associated with a higher incidence of early graft dysfunction (EGD) and graft loss. METHODS: A retrospective study was performed of 540 OLTs carried out consecutively from December 2004 to December 2013. Patients were divided into 2 groups: group A, portal flow <1,000 mL/min; and group B, portal flow >1,000 mL/min. We studied the incidence of EGD and graft survival...

BACKGROUND: The Andalusian community has a specific management model of liver transplantation with a common waiting list, forcing transportation of 45% of hepatic grafts. These trips within the community have been made exclusively via expressway since 2012, sometimes surpassing 400 km in distance. The objective of this study was to analyze the effect of graft transportation on our community regarding postoperative results, primary dysfunction, and short-term graft survival. METHODS: This was a retrospective observational cohort study that included 110 patients recipients of liver transplants from 2009 to 2012...

Knowledge of the anatomy of the hepatic artery and its variations is important to hepatobiliary and liver transplant surgeons and interventional radiologists. We report a rare anatomic variation of liver hepatic arterial supply: a right accessory hepatic artery arising directly from the celiac trunk and observed at the time of multiorgan procurement. The anatomic variation described in this case occurs in up to 2% of cases and their knowledge is essential to avoid injuries during multiorgan procurement that could require multiple anastomoses or lead to inadvertent vessel injury...

BACKGROUND: The ischemia/reperfusion (I/R) phenomenon can cause the dysfunction of some transplanted organs and other distant organs. Liver surgery success, including transplantations, may depend on the adverse effects of intestinal mucosa injury arising from temporary porta triad occlusion. The study objective was to examine I/R liver effects on the small intestine in rats after N-acetylcysteine (NAC) treatment. METHODS: Twenty-four male Wistar rats were randomly divided into 2 groups...

INTRODUCTION: In liver transplantation, late graft dysfunction can have several causes, particularly rejection, infection, vascular, biliary complications, and others, usually suspected by abnormal liver tests. However, normal liver tests do not confirm a normal graft and liver biopsy could identify unexpected features with repercussions in immunosuppressive therapy. The aim of this study was to determinate the histological abnormalities in patients 10 years after liver allograft transplantation with sustainably normal liver tests and evaluate the changes in immunosuppressive therapy triggered by histological data...
