BACKGROUND & AIMS: Celiac disease is a major public health problem worldwide. Although initially it was reported from countries with predominant Caucasian populations, it now has been reported from other parts of the world. The exact global prevalence of celiac disease is not known. We conducted a systematic review and meta-analysis to estimate the global prevalence of celiac disease. METHODS: We searched Medline, PubMed, and EMBASE for the keywords celiac disease, celiac, celiac disease, tissue transglutaminase antibody, anti-endomysium antibody, endomysial antibody, and prevalence for studies published from January 1991 through March 2016...

With the passage of the Affordable Care Act (ACA) followed by the physician payment reform, there is an urgent need to better understand the complex relationships between structure (including incentives), processes, and outcomes of health care and, based on this understanding, identify interventions that can ensure delivery of high value care to patients with liver disease. As hepatologists, how do we systematically address these issues and ensure that we provide high-value care to our patients? These factors combine in the burgeoning field of health services research...

BACKGROUND: Liver transplantation (LT) is a successful treatment for both acute liver failure and end-stage liver disease. The number of women of reproductive age undergoing LT is increasing. Pregnancy outcomes are favourable but there is still a lack of prognostic markers. We aimed to identify factors predictive of adverse pregnancy outcomes in LT recipients. METHODS: An analysis of all pregnancies occurring in LT recipients from 1989-2016 at King's College Hospital was performed...

Anti-TNFα-antibodies have revolutionized the therapy of inflammatory bowel diseases and other immune-mediated inflammatory diseases. Due to the increasing application of these substances, the Working Group of Inflammatory Bowel Diseases of the Austrian Association of Gastroenterology and Hepatology intended to update their consensus report on the safe use of Infliximab (published in 2010) and to enlarge its scope to cover all anti-TNFα-antibodies. The present consensus report summarizes the current evidence on the safe use of anti-TNFα-antibodies and covers the following topics: general risk of infection, bacterial infections (i...

The rapidly growing field of functional, molecular and structural bio-imaging is providing an extraordinary new opportunity to overcome the limits of invasive liver biopsy and introduce a "digital biopsy" for in vivo study of liver pathophysiology. To foster the application of bio-imaging in clinical and translational research, there is a need to standardize the methods of both acquisition and the storage of the bio-images of the liver. It can be hoped that the combination of digital, liquid and histologic liver biopsies will provide an innovative synergistic tri-dimensional approach to identifying new aetiologies, diagnostic and prognostic biomarkers and therapeutic targets for the optimization of personalized therapy of liver diseases and liver cancer...

Liver progenitor cells (LPCs)/ductular reactions (DRs) are associated with inflammation and implicated in the pathogenesis of chronic liver diseases. However, how inflammation regulates LPCs/DRs remains largely unknown. Identification of inflammatory processes that involve LPC activation and expansion represent a key step in understanding the pathogenesis of liver diseases. In the current study, we found that diverse types of chronic liver diseases are associated with elevation of infiltrated interleukin (IL)-17-positive (+) cells and cytokeratin 19 (CK19)+ LPCs, and both cell types colocalized and their numbers positively correlated with each other...

Increasingly, evidence suggests that exposure to maternal obesity creates an inflammatory environment in utero , exerting long-lasting postnatal signatures on the juvenile innate immune system and microbiome that may predispose offspring to development of fatty liver disease. We found that exposure to a maternal Western-style diet (WD) accelerated fibrogenesis in the liver of offspring and was associated with early recruitment of proinflammatory macrophages at 8-12 weeks and microbial dysbiosis as early as 3 weeks of age...

Primary hepatocyte culture is an important in vitro system for the study of liver functions. In vivo , hepatocytes have high oxidative metabolism. However, oxygen supply by means of diffusion in in vitro static cultures is much less than that by blood circulation in vivo . Therefore, we investigated whether hypoxia contributes to dedifferentiation and deregulated metabolism in cultured hepatocytes. To this end, murine hepatocytes were cultured under static or shaken (60 revolutions per minute) conditions in a collagen sandwich...

Insulin resistance is a key risk factor in the progression of nonalcoholic fatty liver disease (NAFLD) and may lead to liver fibrosis. Natural killer (NK) cells are thought to exert an antifibrotic effect through their killing of activated hepatic stellate cells (HSCs). Here, we investigated how the interplay between NK cells and HSCs are modified by insulin resistance in NAFLD. Fresh peripheral blood NK cells (clusters of differentiation [CD]56dim , CD16+ ) were collected from 22 healthy adults and 72 patients with NAFLD not currently taking any medications and without signs of metabolic syndrome...

Vinyl chloride (VC), a common industrial organochlorine and environmental pollutant, has been shown to directly cause hepatic angiosarcoma and toxicant-associated steatohepatitis at high exposure levels. However, the impact of lower concentrations of VC on the progression of underlying liver diseases (e.g., nonalcoholic fatty liver disease [NAFLD]) is unclear. Given the high prevalence of NAFLD in the United States (and worldwide) population, this is an important concern. Recent studies by our group with VC metabolites suggest a potential interaction between VC exposure and underlying liver disease to cause enhanced damage...

Intrahepatic cholangiocarcinoma (iCCA) is a deadly liver primary cancer associated with poor prognosis and limited therapeutic opportunities. Active transforming growth factor beta (TGFβ) signaling is a hallmark of the iCCA microenvironment. However, the impact of TGFβ on the transcriptome of iCCA tumor cells has been poorly investigated. Here, we have identified a specific TGFβ signature of genes commonly deregulated in iCCA cell lines, namely HuCCT1 and Huh28. Novel coding and noncoding TGFβ targets were identified, including a TGFβ-induced long noncoding RNA (TLINC), formerly known as cancer susceptibility candidate 15 (CASC15)...

Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are two major immune-mediated chronic liver diseases. Overlap syndrome (OS) is diagnosed if patients have features of both AIH and PBC; however, there is no consensus on the definition or diagnostic criteria for OS. Here, we report a new scoring classification for OS and evaluate its usefulness. This new scoring classification was developed by modifying the International Autoimmune Hepatitis Group classification by selecting histologic features of AIH and PBC along with modifications of biochemical and immunologic characteristics...

Patients with cirrhosis have high admission and readmission rates, and it is estimated that a quarter are potentially preventable. Little data are available regarding nonmedical factors impacting triage decisions in this patient population. This study sought to explore such factors as well as to determine provider perspectives on low-acuity clinical presentations to the emergency department, including ascites and hepatic encephalopathy. A survey was distributed in four liver transplant centers to both emergency medicine and hepatology providers, who included attending physicians, house staff, and advanced practitioners; 196 surveys were returned (estimated response rate 50...

Liver fibrosis is a common complication associated with transient myeloproliferative disorder (TMD) in Down syndrome (DS). The exact molecular pathogenesis that regulates disease progression is largely unknown. We recently found serum and/or urinary monocyte chemoattractant protein-1 (MCP-1) as a novel biomarker of liver fibrosis. This study was an in vitro analysis to investigate the fibrogenic activity of MCP-1 using the collagen-producing LX-2 human hepatic stellate cell line. We also examined the fibrogenic activity of serum from a male neonate with DS in whom late-onset liver fibrosis developed even after the resolution of TMD...

Background: There is evidence that the financial crisis has deleteriously affected scientific output. We aimed to assess the dynamics of Greek publications in gastroenterology and hepatology over the last ten years. Methods: Data were collected from SCImago. The average annual growth rate (AAGR) of total and citable documents published in Greece in the field of gastroenterology and hepatology was compared with that of cardiology, surgery, and radiology. In addition, it was compared with the corresponding rates in Belgium, Ireland and Portugal...

Introduction: Although registries can rapidly identify clinical study participants, it is unknown which follow up methods for recruiting are most effective. Our goal is to examine the efficacy of three communication strategies for recruiting and enrolling patients who were identified via a contact registry (i.e., registry linked to a consent to re-contact program). Methods: Patients who met the study criteria were identified via the contact registry and targeted for recruitment...

The introduction of solid food is necessary for any infant in order to provide adequate nutrition because when they grow up milk is insufficient for their nutritional needs. Infants born preterm have increased nutritional requirements. The high nutrient demands as well as the organ immaturity of preterm infants combine to render it difficult to achieve dietary intakes that will allow preterm infants to match their in utero growth rates. Current guidelines for the introduction of solid food to term infants cannot be directly translated to preterm infants...
