Treatment of fulminant acute Hepatitis B with nucles(t)id analogues is safe and does not lead to secondary chronification of Hepatitis B.

 Acute hepatitis B virus (HBV) infection is still a major cause of acute liver failure (ALF), necessitating a high rate of emergency liver transplantation (LTx). Acute infection is followed by high viral replication rates leading to hepatocyte death and, ultimately, ALF. The objective of treating HBV-induced ALF thus is to eliminate, or significantly suppress, HBV replication and therefore reduce cell death and support regeneration.

Liver steatosis in pre-transplant liver biopsies can be quantified rapidly and accurately by nuclear magnetic resonance analysis.

Donor livers marginally acceptable or acceptable according to extended criteria are more frequently transplanted due to the growing discrepancy between demand and availability of donor organs. One type of marginally acceptable graft is a steatotic donor liver, because it is more sensitive to ischemia-reperfusion injury. Thus, quantitative assessment of steatosis is crucial prior to liver transplantation.

Compensation of feature selection biases accompanied with improved predictive performance for binary classification by using a novel ensemble feature selection approach.

Motivation: Biomarker discovery methods are essential to identify a minimal subset of features (e.g., serum markers in predictive medicine) that are relevant to develop prediction models with high accuracy.

Multimodal therapy of recurrent and refractory bleeding from esophageal varices - case report and review of the literature.

Bleeding from esophageal varices is a major cause of mortality in patients with advanced liver disease. Although standard treatment and secondary prophylaxis are effective, in some patients sustained hemostasis cannot be achieved. We report the case of a woman with alcoholic liver disease in whom pharmacological, endoscopic, and intravascular therapies failed to control variceal bleeding.

Liver transplantation from HCV RNA-positive donors in the era of interferon-free HCV therapeutics: a re-examination of the situation.

Although the availability of donor organs is limited, liver grafts from HCV-positive donors remained yet an obstacle, primarily because of limited therapeutic options for HCV reinfection and lower rates of graft and patient survival. However, new interferon-free regimens containing direct-acting antiviral agents have fewer adverse effects and better effectiveness, making HCV treatment feasible early after transplant. In 2014, we successfully used sofosbuvir and ribavirin to treat a patient with HCV genotype 3 cirrhosis who was listed for liver transplantation.

Infliximab and Dexamethasone Attenuate the Ductular Reaction in Mice.

Chronic hepatic injury is accompanied by a ductular response that is strongly correlated with disease severity and progression of fibrosis. To investigate whether anti-inflammatory drugs can modulate the ductular response, we treated mice suffering from a steatotic or cholestatic injury with anti-TNF-α antibodies (Infliximab) or glucocorticoids (Dexamethasone). We discovered that Dexamethasone and Infliximab can both modulate the adaptive remodeling of the biliary architecture that occurs upon liver injury and limit extracellular matrix deposition.

Cell death mechanisms in human chronic liver diseases: a far cry from clinical applicability.

The liver is constantly exposed to a host of injurious stimuli. This results in hepatocellular death mainly by apoptosis and necrosis, but also due to autophagy, necroptosis, pyroptosis and in some cases by an intricately balanced combination thereof. Overwhelming and continuous cell death in the liver leads to inflammation, fibrosis, cirrhosis, and eventually hepatocellular carcinoma.

Spleen and Liver Stiffness Is Positively Correlated with the Risk of Esophageal Variceal Bleeding.

Background/aims: Portal hypertension (PH) is a common complication of chronic liver disease and results in esophageal and gastric variceal bleeding, which is associated with a high mortality rate. Measurement of the hepatic venous pressure gradient (HVPG) is considered the gold standard for diagnosing PH and estimating the risk of varices and bleeding. In contrast, upper gastrointestinal (GI) endoscopy (UGE) can reliably demonstrate the presence of varices and bleeding.

Code generator for implementing dual tree complex wavelet transform on reconfigurable architectures for mobile applications.

The authors aimed to develop an application for producing different architectures to implement dual tree complex wavelet transform (DTCWT) having near shift-invariance property. To obtain a low-cost and portable solution for implementing the DTCWT in multi-channel real-time applications, various embedded-system approaches are realised. For comparison, the DTCWT was implemented in language on a personal computer and on a PIC microcontroller.

Morbidity and Mortality Rounds in Liver Transplantation.

Background: Morbidity and mortality conferences (MMCs) provide powerful opportunities for learning, reflection, and improvement. The current literature gives examples of how MMCs can be designed; however, no systematic review of cases and no original data related to liver transplantation are available. Liver transplantation requires a multidisciplinary approach to case identification, presentation, and analysis.

NASH Cirrhosis - the New Burden in Liver Transplantation: How Should It Be Managed?

Background: Non-alcoholic fatty liver disease (NAFLD) is a continuously increasing cause of chronic liver disease and a health burden in all populations affected by the obesity and metabolic syndrome pandemic. Cirrhotic alterations or hepatocellular carcinoma developing from NAFLD may require liver transplantation (LTx).

Methods: Current literature was screened for data on LTx in the setting of NAFLD.

Bathing in carbon dioxide-enriched water alters protein expression in keratinocytes of skin tissue in rats.

Beneficial effects of balneotherapy using naturally occurring carbonated water (CO enriched) have been known since the Middle Ages. Although this therapy is clinically applied for peripheral artery disease and skin disorder, the underlying mechanisms are not fully elucidated.Under controlled conditions, rats were bathed in either CO-enriched water (CO content 1200 mg/L) or tap water, both at 37 °C, for 10 min daily over 4 weeks.

Rescue therapy of a refractory rectal variceal bleeding in a cirrhotic patient by Linton-Nachlas tube and TIPS implantation in combination with variceal embolization.

 Transjugular intrahepatic portosystemic shunt (TIPS) is considered the gold standard for treatment of gastrointestinal variceal bleeding refractory to endoscopic therapy in patients with portal hypertension. Clinically relevant hemorrhage from rectal varices is less frequent than from other sources, and the therapeutic role of TIPS is still ambiguous.  A 57-year-old female patient was referred to us in December 2015 with severe signs of decompensated alcohol-induced liver cirrhosis.

Rotational thromboelastometry can detect factor XIII deficiency and bleeding diathesis in patients with cirrhosis.

Background & Aims: Patients with progressive liver disease exhibit complex coagulation disorders. Factor XIII plays a crucial role in the last steps of haemostasis, and its deficiency is associated with an increased incidence of bleeding diathesis. However, current conventional coagulation tests cannot detect factor XIII deficiency.

Macrophage Depletion Attenuates Extracellular Matrix Deposition and Ductular Reaction in a Mouse Model of Chronic Cholangiopathies.

Chronic cholangiopathies, such as primary and secondary sclerosing cholangitis, are progressive disease entities, associated with periportal accumulation of inflammatory cells, encompassing monocytes and macrophages, peribiliary extracellular matrix (ECM) deposition and ductular reaction (DR). This study aimed to elucidate the relevance of macrophages in the progression of chronic cholangiopathies through macrophage depletion in a 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) mouse model. One group of mice received a single i.

Human Ex-Vivo Liver Model for Acetaminophen-induced Liver Damage.

Reliable test systems to identify hepatotoxicity are essential to predict unexpected drug-related liver injury. Here we present a human ex-vivo liver model to investigate acetaminophen-induced liver injury. Human liver tissue was perfused over a 30 hour period with hourly sampling from the perfusate for measurement of general metabolism and clinical parameters.

Evolution of management in peritoneal surface malignancies.

Management of peritoneal surface malignancies has gradually evolved by the introduction of cytoreductive surgery in combination with intraperitoneal chemotherapy applications. Recently, peritoneal metastases of intraabdominal solid organ tumors and primary peritoneal malignancies such as peritoneal mesothelioma are being treated with this new approach. Selection criteria are important to reduce morbidity and mortality rates of patients who will experience minimal or no benefit from these combined treatment modalities.

Quantitative proteome analysis reveals the correlation between endocytosis-associated proteins and hepatocellular carcinoma dedifferentiation.

The majority of poorly differentiated hepatocellular carcinomas (HCCs) develop from well-differentiated tumors. Endocytosis is a cellular function which is likely to take part in this development due to its important role in regulating the abundances of vital signaling receptors. Here, we aimed to investigate the abundance of endocytosis-associated proteins in HCCs with various differentiation grades.

[Hepatic steatosis : Differential diagnostics and current aspects].

The frequency of non-alcoholic fatty liver disease (NAFLD) has continously increased over the last few decades in parallel with the increasing prevalence of metabolic syndrome. With the increasing frequency of obesity and type 2 diabetes an increase in non-alcoholic steatohepatitis (NASH) is also to be expected. The NASH-associated liver cirrhosis and primary hepatocellular carcinoma (HCC) are indications for liver transplantation (LTX), which is gaining importance in Germany.

Economic growth leads to increase of obesity and associated hepatocellular carcinoma in developing countries.

 Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and the third leading cause of cancer related death worldwide. In recent years, the prevalence of HCC has increased in both developing and developed countries. Most HCC cases develop in the presence of advanced chronic liver disease related to viral hepatitis.

Liver Failure due to Acute Viral Hepatitis (A-E).

Background: Viral hepatitis is still one of the key causes of acute liver failure (ALF) in the world.

Methods: A selective literature search of the PubMed database was conducted, including current studies, reviews, meta-analyses, and guidelines. We obtained an overview of ALF due to viral hepatitis in terms of epidemiology, course, and treatment options.

Markers of Hippo-Pathway Activity in Tumor Forming Liver Lesions.

Hepatocellular Carcinoma (HCC) is a lethal cancer worldwide. Recently, the hippo signaling pathway has been implicated in tumorigenesis of HCC and other malignant tumors. Aim of the study was therefore to evaluate the hippo signaling pathway activity and its clinico-pathological associations and crosstalk in different tumor forming hepatocellular lesions (HCC, hepatocellular adenoma (HCA), focal nodular hyperplasia (FNH) and cirrhosis).
