Although extensively s … We also highlight the contribution of CD38-mediated signaling to hepatic fibrogenesis and end-stage liver failure as well as its potential role in liver transplantation, particularly post-transplant related conditions including ischemic injury and acute cellular rejection. Given its impact on multiple intracellular processes, CD38 has emerged as a promising the …

Biopsy-confirmed fenofibrate-induced severe jaundice: A case report.

BACKGROUND: Drug-induced liver injury (DILI) is the leading cause of acute liver failure in the United States. DILI is mainly caused by painkillers and fever reducers, and it is often characterized by the type of hepatic injury (hepatocellular or cholestatic). This report presents a case of fenofibrate-induced severe jaundice in a 65-year-old Korean male with no prior history of liver disease. We offer a strategy for patients who present signs of severe liver injury with jaundice and high elevations in serum transaminases. CASE SUMMARY: A 65-year-old male visited the gastroenterology outpatie…

Hepatoprotection and hepatotoxicity of Chinese herb Rhubarb (Dahuang): How to properly control the "General (Jiang Jun)" in Chinese medical herb.

Chinese herb Rhubarb (Dahuang), one of the most widely used traditional Chinese medicine in clinical application for over a thousand years and known as the "General (Jiang Jun)" in Chinese medical herb, currently used clinically for long-term treatment of gastrointestinal diseases and chronic liver diseases. Through previous researches, it has been identified that Rhubarb possessed a good hepatoprotective effect, which primarily protected liver from oxidation, fibrosis and cirrhosis, liver failure, hepatocellular carcinoma and various types of hepatitis. Meanwhile, it has been recently reporte…

Development of an Ethanol-induced Fibrotic Liver Model in Zebrafish to Study Progenitor Cell-mediated Hepatocyte Regeneration.

Sustained liver fibrosis with continuation of extracellular matrix (ECM) protein build-up results in the loss of cellular competency of the liver, leading to cirrhosis with hepatocellular dysfunction. Among multiple hepatic insults, alcohol abuse can lead to significant health problems including liver failure and hepatocellular carcinoma. Nonetheless, the identity of endogenous cellular sources that regenerate hepatocytes in response to alcohol has not been properly investigated. Moreover, few studies have effectively modeled hepatocyte regeneration upon alcohol-induced injury. We recently rep…

Selective bowel decontamination improves the survival of 90% hepatectomy in rats.

BACKGROUND: Clinically, hepatectomy is a clean procedure performed without routine antimicrobial prophylaxis, regardless of the extent of liver loss. Translocation of endotoxin has been recognized as a fatal complication leading to liver failure. After extended hepatectomy, the portal hypertension, mucosal damage, intrahepatic bile acid retention, inhibited enterokinesia, and so forth are likely to contribute to enhanced endotoxin absorption. The effect of selective bowel decontamination (SBD) on the prognosis of hepatectomy were investigated. METHODS: We adopted rat models of partial hepatec…

Случай первичного бильярдного цирроза и аутоиммунного гепатита, характеризующийся острым представлением и переходной серопозитивностью иммуноглобулина G и антиядерного антитела.

Аутоиммунный гепатит (АГИ) обычно считается клиническим и гистологическим "хроническим" гепатитом. Она часто демонстрирует острое представление, как острый гепатит, без типичных клинепатологических особенностей АИЗ, особенно в случае частичного совпадения с первичным циррозом цирроза (КМС). 52-летний мужчина впервые показал легкую дисфункцию печени во время ежегодного медицинского осмотра. Два месяца спустя он показал желтуху, и лабораторные тесты выявили высоту ферментов печени, гипербилирубинемии и продолжительную протромбиновую активность во времени, как острая недостаточность печени. Антим

Pharmacokinetic study of recombinant human hepatocyte growth factor administered in a bolus intravenously or via portal vein.

Hepatocyte growth factor (HGF) stimulates liver regeneration and has the potential to be a therapeutic agent for fatal liver diseases, including fulminant hepatic failure and liver cirrhosis. In this study, we investigated the pharmacokinetics of recombinant human HGF, which will be soon available for clinical applications. When recombinant human HGF (0.1mg/kg) was administered intravenously to normal rats, serum levels of human HGF increased to 89.7+/-20.6ng/ml 5min after the bolus injection, followed by a decrease with a half-life of 2.4min. Recombinant HGF administered intravenously was dis

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2) continues to cause su … ndary sclerosing cholangitis. Furthermore, the virus can promote existing chronic liver diseases to liver failure and activate the autoimmune liver disease. Whether the direct cytopathic effects of the virus, host reaction, hypoxia, drugs, vaccination, or all these risk factors cause liver injury has not been clarified to a large extent in COVID-19. This review …

Is type 2 diabetes mellitus a predisposal cause for developing hepatocellular carcinoma?

Hepatic cancer stands as one of the frontier causes of cancer related mortality worldwide. Among the several risk factors already established, type 2 diabetes is now considered as one of the important risks in progression of liver cancer. Studies have shown that likelihood of occurrence of liver cancer is many folds higher in patients diagnosed with type II diabetes compared to patients without diabetes. Liver plays an important role in metabolism of glucose in our body, so may be type II diabetes as it is an important epiphenomenon of hepatic diseases such as liver cirrhosis, liver failure, f…

Increased transfusion-free survival following auxiliary pig liver xenotransplantation.

BACKGROUND: Pig to baboon liver xenotransplantation typically results in severe thrombocytopenia and coagulation disturbances, culminating in death from hemorrhage within 9 days, in spite of continuous transfusions. We studied the contribution of anticoagulant production and clotting pathway deficiencies to fatal bleeding in baboon recipients of porcine livers. METHODS: By transplanting liver xenografts from α1,3-galactosyltransferase gene-knockout (GalT-KO) miniature swine donors into baboons as auxiliary organs, leaving the native liver in place, we provided the full spectrum of primate clo

Liver abnormalities in connective tissue diseases.

The liver is a lymphoid organ involved in the immune response and in the maintenance of tolerance to self molecules, but it is also a target of autoimmune reactions, as observed in primary liver autoimmune diseases (AILD) such as autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis. Further, the liver is frequently involved in connective tissue diseases (CTD), most commonly in the form of liver function test biochemical changes with predominant cholestatic or hepatocellular patterns. CTD commonly affecting the liver include systemic lupus erythematosus, antiphosp

Domino liver transplantation: how far can we push the paradigm?

Domino liver transplantation (DLT) has emerged as a strategy for increasing the number of liver grafts available: morphologically normal livers from donors with metabolic diseases can be used for select recipients with hepatocellular carcinoma (usually outside the Milan criteria). Familial amyloidotic polyneuropathy (FAP) is the most common indication for DLT. When FAP patients are involved in DLT, the indications and outcomes are clear and good, although de novo FAP development within various periods of time has been described in DLT recipients of FAP livers. With the increasing need for orga

Chyme Reinfusion in Intestinal Failure Related to Temporary Double Enterostomies and Enteroatmospheric Fistulas.

Some temporary double enterostomies (DES) or entero-atmospheric fistulas (EAF) have high output and are responsible for Type 2 intestinal failure. Intravenous supplementations (IVS) for parenteral nutrition and hydration compensate for intestinal losses. Chyme reinfusion (CR) artificially restores continuity pending surgical closure. CR treats intestinal failure and is recommended by European Society for Clinical Nutrition and Metabolism (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN) when possible. The objective of this study was to show changes in nutritional status

Recurrent primary disease and de novo nephritis following renal transplantation.

Recurrent or de novo diseases account for only 5% of graft failure in children, but have much to teach us about mechanisms. In children, almost the only metabolic disease with recurrence is type I hyperoxaluria, in which the poor long-term results of isolated renal transplantation make combined liver and renal transplantation, or even prophylactic liver transplantation before renal failure the preferable alternatives. While many forms of nephritis may show histological recurrence in allografts, it is notable that in many patients this is accompanied by no clinical manifestations or only mild d

Toxic hepatic failure in newborn foals.

Eight foals, 2 to 5 days of age, with similar clinical signs and laboratory and pathologic findings, died from hepatic failure. The predominant clinical signs were depression and icterus. Abnormally high values were found for plasma ammonia content, aromatic-to-branch-chain amino acid ratio, total serum bilirubin content, gamma glutamyl transferase activity, alkaline phosphatase activity, and PCV; partial thromboplastin time and prothrombin time were prolonged. Some foals had high sorbitol dehydrogenase activity. These laboratory findings were suggestive of subacute hepatic disease and failure

The failure of nonoperative management in pediatric solid organ injury: a multi-institutional experience.

BACKGROUND: Nonoperative management (NOM) is the accepted treatment of most pediatric solid organ injuries (SOI) and, is typically successful. We sought to elucidate predictors of, and the time course to, failure in the subset of children suffering SOI who required operative intervention. METHODS: A retrospective analysis was performed from January 1997 through December 2002 of all pediatric patients (age 0-20 years) with a SOI (liver, spleen, kidney, pancreas) from the trauma registries of seven designated, level I pediatric trauma centers. Failure of NOM was defined as the need for intra-ab

Hemophagocytic Lymphohistiocytosis and the Liver Masquerade.

We present a case of hemophagocytic lymphohistiocytosis (HLH) with a complex presentation that could have been easily mistaken as one of many alternative diagnoses. Our patient, with chronic alcohol use disorder, presented with new-onset liver symptoms and pancytopenia. This case underscores the importance of clinical suspicion and further investigation of a wide differential. The purpose of this case report is to highlight the diagnostic challenges and nuances in patient presentation that can mislead healthcare providers while emphasizing the ambiguity of liver failure symptoms in patients wi…
