High-risk primary biliary cholangitis (PBC), defined by inadequate response at one year to Ursodeoxycholic acid (UDCA), is associated with disease progression and liver transplantation. Stratifying high-risk patients early would facilitate improved approaches to care. Using long-term follow-up data to define risk at presentation, 6 high-risk PBC patients and 8 low-risk patients were identified from biopsy, transplant and biochemical archival records. Formalin-fixed paraffin-embedded (FFPE) liver biopsies taken at presentation were graded (Scheuer and Nakanuma scoring) and gene expression analysed using the NanoString® nCounter PanCancer Immunity 770-gene panel...

The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is on the rise. The 2 well recognized HCC risk factors in thalassemia are iron overload and chronic viral infection with hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, which results in genotoxicity, and to immunologic dysregulation, which attenuates cancer immune surveillance. Chronic hepatitis B and C infections lead to necroinflammation, which can prompt progression to HCC, but an independent role of hepatitis B virus in hepatic carcinogenesis among patients with thalassemia has not been demonstrated...

Hepatoblastoma (HBL), the most common childhood liver cancer is cured with surgical resection after chemotherapy or with liver transplantation if local invasion and multifocality preclude resection. However, variable survival rates of 60-80% and debilitating chemotherapy sequelae argue for more informed treatment selection, which is not possible by grading the Wnt-β-catenin over activity present in most HBL tumors. A hypothesis-generating whole transcriptome analysis shows that HBL tumors removed at transplantation are enriched most for cancer signaling pathways which depend predominantly on epidermal growth factor (EGF) signaling, and to a lesser extent, on aberrant Wnt-β-catenin signaling...

Likely, maintained organ and notably cerebral perfusion, secures rapid recovery following anesthesia. To secure cerebral blood flow (CBF) at least mean arterial pressure (MAP) and the arterial carbon dioxide tension (PaCO2) need to be considered. CBF is "autoregulated", i.e. stays more or less stable within a MAP of 50-150 mmHg, but the lower limit appears to depend on the central blood volume and/or cardiac output, illustrated by a decrease in CBF at a MAP of 80 mmHg with a compromised central blood volume, while CBF remains constant with a MAP < 40 mmHg, if the central blood volume is maintained...

BACKGROUND Right lobe living donor liver transplantation (LDLT) remains the most common form of liver transplantation in Asia. However, reconstruction of the venous outflow in a right liver allograft may pose technical difficulties if hepatic venous variations are present. Recently, much emphasis has been given to the reconstruction of large and multiple inferior right hepatic veins (IRHVs). The method of reconstructive technique, type of vascular grafts, and the outcome after the procedure have been a point of debate...

BACKGROUND The risk of liver cirrhosis is higher among individuals with diabetes mellitus, and a cirrhotic patient with diabetes may have a poorer prognosis after liver transplantation compared to a patient without diabetes. Thus, we evaluated whether fasting plasma glucose prior to receiving a liver transplant was a prognostic factor for post-transplant survival. MATERIAL AND METHODS Ninety-one patients received a living donor liver transplant between November 2005 and December 2012. Patients were considered diabetic if they were prescribed diabetes medications or had impaired glucose tolerance as measured by an oral glucose tolerance test...

Score sheets were first introduced 30 years ago to assess pain, distress and suffering in animals. To date, however, there is still no general agreement on their use in research practice, and only a few publications can be found on this topic. In the present work, we demonstrate the use of a special score sheet for severity assessment in the first three postoperative days in two showcased studies performed on Wistar and Lewis rats undergoing liver resection or orthotopic liver transplantation, respectively...

Obesity is an alarming global health problem that results in multiaspect metabolic syndromes in both genders and most age groups. The lack of effective therapies for obesity and its associated metabolic syndrome is an urgent societal issue. To elucidate whether mesenchymal stromal cell (MSC)-based therapies can ameliorate high-fat diet-induced obesity and compare the effectiveness of several methodological approaches, we transplanted human MSCs, MSC-derived brown adipocytes (M-BA), and MSC lysateinto obese mice...

BACKGROUND: Pancreatitis is a serious complication after cardiac surgery and can lead to significant morbidities and mortality. The incidence of pancreatitis is even higher in patients undergoing heart transplantation than in those undergoing other cardiac surgeries. Nevertheless, the clinical presentations of pancreatitis are frequently atypical in these patients. CASE PRESENTATION: We report a heart recipient who was complicated with acute right heart failure initially after orthotopic heart transplantation and developed devastating unanticipated hemorrhagic pancreatitis 1 month after the transplantation...

BACKGROUND: Cholangiocarcinoma (CCA) is a leading cause of death in patients with primary sclerosing cholangitis (PSC). Biliary polysomy detected by fluorescence in situ hybridization (FISH) helps to identify patients with early CCA, but not all PSC patients with polysomy develop CCA. Here, we examined the features and clinical outcomes of PSC patients with serial versus isolated polysomy. METHODS: All patients with PSC who underwent ≥1 endoscopic retrograde cholangiography (ERC) with FISH testing at Mayo Clinic, Rochester from 2008-2011 were identified...

Viral hepatitis B still represents a major epidemiological issue worldwide. After recombinant vaccine administration, a titer of anti-HBs antibodies ≥ 10 IU/L has long been considered to be seroprotective. Persons without this antibody level after complete vaccination are referred to as non-responders. A progressive decline in anti-HBs levels over years is also commonly seen in responders. Recently, there has been increasing evidence that the titer of anti-HBs ≥ 10 IU/L does not provide 100 % protection against infection and clinically manifest illness...

BACKGROUND: Guidelines recommend that patients with hepatitis C virus (HCV)-related liver disease be treated for HCV before liver transplant (LT) to eliminate the virus prior to surgery. However, the unpredictability of donor organ availability may limit treatment duration. Interruption of HCV treatment with resumption post-LT is one potential solution which has not been investigated widely. METHODS: Patients from 5 clinical centres included in the large, national, noninterventional Hepa-C registry who started treatment with direct-acting antiviral agents (DAAs) while awaiting LT were identified retrospectively and followed up prospectively...

BACKGROUND: A measure of donor liver quality, the donor liver index, was developed and validated for the UK population of transplant recipients. Unlike previously proposed measures, this index is only based on variables that are available at the point of retrieval, and so does not include cold ischaemic time. METHODS: Indices of liver quality were based on data from the UK Transplant Registry on all 7929 liver transplants between January 2000 and December 2014. RESULTS: The donor liver index (DLI) was based on factors shown to affect graft survival, which included donor age, sex, height, type (donor after brain death or circulatory death), bilirubin, smoking history, and whether the liver was split...

BACKGROUND: Geographic disparities persist in access to liver transplantation. Candidates with similar urgency experience varying opportunities for transplants across the US. Policymakers are poised to act and 1 proposal entails reorganizing the current OPTN of 11 regions into 8 districts. However, redistricting has the shortcomings that OPOs are disconnected from their immediate neighbors by district borders and that it is not easily responsive to uncertainty resulting from variability in donor and listing rates...

: Primary biliary cholangitis (PBC) is a chronic, progressive autoimmune liver disease that mainly affects middle-aged women. Obeticholic acid (OCA), which was recently approved by the Food and Drug Administration for PBC treatment, has demonstrated positive effects on biochemical markers of liver function. Our objective was to evaluate the long-term clinical impact and cost-effectiveness of OCA as a second-line treatment for PBC in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA...

: The availability of oral direct-acting antiviral (DAAs) has altered the hepatitis C virus (HCV) treatment paradigm for both pre- and post-liver transplant (LT) patients. There is a perceived trade-off between pre- versus post-LT treatment of HCV-treatment may improve liver function but potentially decrease the likelihood of a necessary LT. Our objective was to identify LT-eligible patients with decompensated cirrhosis who would benefit (and not benefit) from pre-LT treatment based on their MELD scores...

BACKGROUND: Recurrent hepatocellular carcinoma after a patient's initial therapy, whether it is transplantation, resection, or ablation, remains a challenging clinical problem. Since recurrence occurs in 70% of all initially treated disease within 5 years, optimal management to treat this recurrence is needed. Currently, a bias exists toward mono-therapy (i.e., ablation alone, hepatic arterial therapy alone, or sorafenib therapy alone) instead of concurrent sequential therapy-as is common in other primary and metastatic disease to the liver...

Yaoping Shi, Bo Zhai
BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. SUMMARY: This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques...

BACKGROUND: The study was designed to assess the role of preoperative neutrophil, lymphocyte, and neutrophil-lymphocyte ratio (NLR) in predicting survival outcomes of ABO-incompatible liver transplantation (LT). MATERIALS AND METHODS: We retrospectively collected the demographic and clinical characteristics of 71 patients with end-stage liver cirrhosis following ABO-incompatible LT in this study. Kaplan-Meier survival analysis and Cox multiple factors regression analysis were performed to determine the independent risk factors from preoperative blood parameters for poor prognosis...
