: 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...

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: Hepatitis C is a significant cause for end-stage liver diseases and liver transplantation which affects approximate 3% of the global populations. Despite the present of several direct antiviral agents in the treatment of hepatitis C, the standard treatment for HCV is accompanied by several drawbacks such as adverse side effects, high pricing of medications and the rapid emerging rate of resistant HCV variants. OBJECTIVES: To discover potential inhibitors for HCV helicase through an optimized in silico approach...

PURPOSE: The spleen presents numerous functions, including the production of immunoglobulins and blood filtration, removing microorganisms and cellular debris. The spleen also has anatomical and functional relationship with the liver, but there are few studies on this topic. The aim of this study was to assess the effect of splenectomy and autologous spleen transplantation on both filtering functions of spleen and acetaminophen-induced hepatotoxicity. MATERIALS AND METHODS: Fifty-two BALB/c mice were randomized into four groups: splenectomized; splenectomy and splenic autotransplantation in the greater omentum; sham operated control; and non-operated control...

Hepatic metastases are one of the most important prognostic factors for survival among patients affected by gastrointestinal neuroendocrine tumors (NETs). The present study aims to evaluate the impact of surgery, including hepatic resection or orthotopic liver transplantation (OLT), on the outcome of patients affected by hepatic metastases from NETs, in terms of overall survival (OS). In this multicentric retrospective study, data was collected on 26 patients, who underwent surgery for hepatic metastases from NETs in two Italian University Clinics between January 1990 and December 2012; of which, 22 patients underwent hepatic resective surgery and 4 patients OLT...

BACKGROUND AND AIMS: The AFP model was shown superior to Milan criteria for prediction of HCC recurrence after liver transplantation in a French population. Our aim was to test the AFP model in a non French, post-hepatitic cirrhosis-based population of HCC candidates. METHODS: 574 patients transplanted for HCC in 4 Italian centres were studied. AFP score was assessed at last evaluation before LT. Probabilities of recurrence and survival were estimated by the log rank test or competing risk analysis and compared according to the AFP model...

Non-alcoholic steatohepatitis (NASH) is characterized by liver steatosis and inflammation. Currently, the underlying mechanisms leading to hepatic inflammation are not fully understood and consequently, therapeutic options are poor. Non-alcoholic steatohepatitis (NASH) and atherosclerosis share the same etiology whereby macrophages play a key role in disease progression. Macrophage function can be modulated via activation of receptor-ligand binding of Notch signaling. Relevantly, global inhibition of Notch ligand Delta-Like Ligand-4 (DLL4) attenuates atherosclerosis by altering the macrophage-mediated inflammatory response...

Literature on liver transplantation for use in medical education is limited and as yet unsatisfactory. The aim of this article is to help medical students gain enough insight into the reality of being a liver transplant recipient. This is crucial so in the future they can feel confident in approaching these patients with adequate knowledge and confidence. The knowledge-tree based learning core topics are designed for a 2-h class including indication/contraindication in the real-world setting, model for end stage liver disease scoring and organ allocation policy, liver transplantation for hepatic malignancy, transplantation surgery, immunosuppression strategy in practical consideration, and management of viral hepatitis...

Chronic hepatitis C is a major reason for development of cirrhosis and hepatocellular carcinoma and a leading cause for liver transplantation. The development of direct-acting antiviral agents lead to (pegylated) interferon-alfa free antiviral therapy regimens with a remarkable increase in sustained virologic response (SVR) rates and opened therapeutic options for patients with advanced cirrhosis and liver graft recipients. This concise review gives an overview about most current prospective trials and cohort analyses for treatment of patients with liver cirrhosis and liver graft recipients...

CONTEXT: The discrepancy between donor supply and organ demand increased the possibility of gender and race mismatch between the donors and recipients. However, the findings of their impact on graft and patient survival are outdated and mixed. OBJECTIVE: To estimate the effects of gender and race mismatch on graft survival and patient survival among adult patients (18 years and older) with end-stage liver disease. DESIGN: A total of 38 768 patients undergoing liver transplant between 2002 and 2011 were identified from United Network for Organ Sharing database...

Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) of the liver is a serious, early complication of haematopoietic stem cell transplantation (HSCT), severe and very severe forms of which are associated with a high mortality rate. A wide variety of patient, disease and treatment-related risk factors for VOD/SOS have been identified. Several bodies have published recommendations for the diagnosis, prevention and management of VOD/SOS following HSCT. A group of regional experts have developed a consensus statement on the diagnosis, prevention and management of VOD/SOS in the Middle East and North Africa region to help in the management of HSCT patients in the region...

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein...

Serology is important for the diagnosis and follow-up of human alveolar echinococcosis (AE). However, patient conditions are highly variable among those with AE, and antibody responses in serological follow-up have not been well-defined. We recently described a new AE rat model established by implantation of small AE tissue into a single arbitrary location in the liver; no metastasis and dissemination were observed. In the present study, we examined the serological characteristics in our rat model before and after surgical treatment...

BACKGROUND AND AIMS: Alcoholic liver disease (ALD) is a leading cause of liver failure and mortality. In humans, severe alcoholic hepatitis is associated with key changes of intestinal microbiota (IM), which influences individual sensitivity to develop advanced ALD. We used the different susceptibility to ALD observed in two distinct animal facilities to test the efficiency of two complementary strategies (fecal microbiota transplantation and prebiotic treatment) to reverse dysbiosis and prevent ALD...

Auxiliary liver transplantation (ALT) for Hepatitis B virus (HBV) related liver cirrhosis previously showed poor results, because the native liver was a significant source of HBV recurrence and the graft could be rapidly destroyed by HBV infection in an immunosuppressive condition. Four patients suffering from HBV-related liver cirrhosis were unable to undergo orthotopic liver transplantation because the only available grafts of left lobe were too small. Under entecavir based anti-HBV treatment, they underwent ALT in which the recipient left liver was removed and the small left lobe graft was implanted in the corresponding space...

The successful outcome in orthotopic liver transplantation (OLT) is critically dependent on the uncompromised hepatic graft blood inflow. Arterial conduits represent a good solution in cases where conventional revascularisation is not possible. The purpose of this systematic review is to analyse the published evidence on the use of arterial conduits in adult OLT. After review of the Pubmed and EMBASE databases, 19 relevant studies were identified and analysed. Even though patient survival was comparable, most large studies reported worse 1-, 3- and 5-year graft survival rates compared to grafts with standard arterial revascularisation...
