OBJECTIVES: Noninvasive models have been established for the assessment of liver fibrosis in patients with chronic hepatitis B(CHB). However, the predictive performance of these established models remains inconclusive. We aimed to develop a novel predictive model for liver fibrosis in CHB based on routinely clinical parameters. RESULTS: Platelets(PLT), the standard deviation of red blood cell distribution width(RDW-SD), alkaline phosphatase(ALP) and globulin were independent predictors of significant fibrosis by multivariable analysis...

AIM: To characterize the effect of hepatic steatosis (HS) on the progression of chronic hepatitis B. METHODS: A total of 162 chronic hepatitis B (CHB) patients confirmed by liver biopsy were involved in this study. All subjects were prospectively followed-up for 5 years in real-life clinical practice. Fibrosis stage was determined using aspartate aminotransferase-to-platelet ratio index (APRI). The end-point was cirrhosis, liver cancer or death. The effects of steatosis on the biological behavior of hepatocellular carcinoma cells were investigated using oleic acid-induced lipid accumulation in HepG2, HLE, PLC, and SMMC-7721 cells...

Context: Bile acids (BA) are signalling molecules controlling energy homeostasis which can be both toxic and protective for the liver. BA alterations have been reported in obesity, insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). However whether BA alterations contribute to NASH independently of the metabolic status is unclear. Objective: To assess BA alterations associated with NASH independently of BMI and IR. Design & Setting: Patients visiting the obesity clinic of the Antwerp University Hospital (a tertiary referral facility) were recruited from 2006 to 2014...

BACKGROUND: Recent changes in deceased donor organ allocation for livers (Share-35) and kidneys (KAS) have resulted in broader sharing of organs and increased cold ischemia time (CIT). Broader organ sharing however is not the only cause of increased CIT. METHODS: This was a retrospective registry study of CIT in same-hospital liver transplants (SHLT, n=4,347) and kidney transplants (SHKT, n=9,707) between 2004 and 2014. RESULTS: In SHLT, median (IQR) CIT was 5...

Rare cases of extrapulmonary involvement in Legionella spp. infections have been described, mostly in immunocompromised adults. We report a case of a 2 month old male with reticular dysgenesis variant of severe combined immune deficiency (SCID) with multiple liver lesions. Core-needle biopsies of one liver lesion demonstrated Gram-negative bacilli and a broad-spectrum polymerase chain reaction (PCR) assay detected Legionella pneumophilia.

Non-alcoholic fatty liver disease (NAFLD) is a burgeoning global health concern. In the subset of NAFLD patients with non-alcoholic steatohepatitis (NASH), the presence of significant fibrosis at index assessment is associated with poor prognosis and increased mortality. Hence, there is a growing need to accurately assess and stage fibrosis. Liver biopsy, the current gold standard, has limitations with sampling error and is invasive, with associated inherent risk. This has led to a host of non-invasive means of assessing fibrosis, which has garnered relevance in a disease that requires serial assessment of fibrosis longitudinally over time...

Liver transplantation (LT) has become standard of care in patients with non-resectable early stage hepatocellular carcinoma (HCC) in liver cirrhosis. Currently, patient selection for LT is strictly based on tumor size and number, provided by the Milan criteria. This may, however, exclude patients with advanced tumor load but favourable biology from a possibly curative treatment option. It became clear in recent years that biological tumor viability rather than tumor macromorphology determines posttransplant outcome...

Background and Aims: Hepatitis C virus (HCV) cirrhosis is the leading indication for liver transplantation in the United States and recurrent HCV following liver transplantation is a major cause of allograft loss and mortality. Liver biopsies are commonly used to identify recurrent HCV and determine the need for antiviral therapy. The introduction of direct-acting antiviral agents (DAAs) has changed the management of recurrent HCV infection. This study aimed to describe the role of liver biopsies in liver transplant recipients with HCV after the introduction of DAAs...

Cystic fibrosis liver disease (CFLD) in children causes progressive fibrosis leading to biliary cirrhosis, however its cause(s) and early pathogenesis are unclear. We hypothesised that a bile acid-induced Ductular Reaction (DR) drives fibrogenesis. We evaluated the DR by cytokeratin-7 immunohistochemistry in liver biopsies, staged for fibrosis, from 60 children with CFLD and demonstrated that the DR was significantly correlated with hepatic fibrosis stage and biliary taurocholate levels. To examine the mechanisms involved in DR induction liver progenitor cells (LPCs) were treated with taurocholate and key events in DR evolution were assessed: LPC proliferation, LPC biliary differentiation and hepatic stellate cell (HSC) chemotaxis...

Hepatic myelolipoma is a rare entity with only 17 cases described in the literature. A 73mm right liver mass was fortuitously discovered in a 55-year-old man. The biopsy showed normal hepatic tissue adjacent to a normal medular like hematopoïetic tissue, showing trilieage hematopoieses, including myeloid cells, erythroid cells and megakaryocytic cells. The diagnosis of hepatic myelolipoma was proposed. This benign tumor was initially described in adrenal gland, which is the most common topography. No malignancy or bleeding complication has been described in its hepatical location...

Several research strategies have been used to study the pathogenesis of alcoholic hepatitis (AH). These strategies have shown that various signaling pathways are the target of alcohol in liver cells. However, few have provided specific mechanisms associated with Mallory-Denk Bodies (MDBs) formed in Balloon cells in AH. The formation of MDBs in these hepatocytes is an indication that the mechanisms of protein quality control have failed. The MDB is the result of aggregation and accumulation of proteins in the cytoplasm of balloon degenerated liver cells...

A 34-year old male with a giant condyloma acuminatum of the anus secondary to HIV infection presented to the emergency department with a persistent nose bleed lasting 2-3days, acute anemia, thrombocytopenia, and coagulopathy. The patient also had significant hepatosplenomegaly and elevated liver enzymes which were a new finding since the patient's last hospitalization 1-2month prior to the current admission. A bone marrow biopsy showed diffuse infiltration by carcinoma with neuroendocrine features. The patient quickly developed multi-organ injury, decompensated, and died...

Nonalcoholic fatty liver disease (NAFLD) is a metabolic complication of obesity that encompasses a spectrum of conditions, including hepatic steatosis, nonalcoholic steatohepatitis (NASH), cirrhosis, and end-stage liver disease. Screening for NAFLD is important to limit progression, allow early detection of carcinoma, and follow the need for liver transplantation. Although noninvasive markers exist, hepatic histologic evaluation remains the gold standard for diagnosis. To reduce the risk of complications after liver biopsy but increase the accuracy of NAFLD diagnosis, hepatic tissue can be sampled during bariatric surgery...

Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...

BACKGROUND: Treatment planning especially liver resection in cholangiocarcinoma (CCA) depends on the extension of tumor and lymph node metastasis which is included as a key criterion for operability. Magnetic resonance imaging (MRI) offers a rapid and powerful tool for the detection of lymph node metastasis (LNM) and in the current manuscript is assessed as a critical tool in the preoperative protocol for liver resection for treatment of CCA. However, the accuracy of MRI to detect LNM from CCA had yet to be comprehensively evaluated...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

NAFLD is one of the most important causes of liver disease worldwide and will probably emerge as the leading cause of end-stage liver disease in the coming decades, with the disease affecting both adults and children. The epidemiology and demographic characteristics of NAFLD vary worldwide, usually parallel to the prevalence of obesity, but a substantial proportion of patients are lean. The large number of patients with NAFLD with potential for progressive liver disease creates challenges for screening, as the diagnosis of NASH necessitates invasive liver biopsy...
