Plumbagin is a quinonoid constituent extracted from Plumbago genus, and it exhibits diverse pharmacological effects. This study thoroughly investigated the effects of plumbagin on thioacetamide-induced acute and chronic liver injury. Results shown that plumbagin increased survival rate, reduced liver congestion and inflammation, and decreased macrophages and neutrophils in the fulminant hepatic failure model, and remarkably diminished liver fibrosis and inflammation in the chronic liver injury model. Furthermore, plumbagin significantly suppress the HSCs/myofibroblasts activation by reduced expression of markers α-SMA and COL-1/3, and reduced macrophage in liver...

OBJECTIVES: Autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) are progressive immune-mediated inflammatory diseases that may require liver transplant (LT). Outcomes in children undergoing LT for these diseases are poorly studied in the Pediatric End Stage Liver Disease (PELD) era. We aimed to characterize the outcome of LT in children with AIH and PSC. METHODS: Children ≤18 years with PSC or AIH who had a first, isolated LT from 2002-2012 were identified from the UNOS database...

Liver failure is a frequent and serious complication that causes morbidity and mortality in haematopoietic stem cell transplantation (HCT) recipients. Liver dysfunction in these patients can be related to infectious causes, most common viral hepatitis. We report a case of disseminated acyclovir-resistant herpes simplex virus (HSV) infection following HCT that led to acute liver failure and death. Although rare, HSV hepatitis leads to high morbidity and mortality and should be considered in the differential diagnosis of HCT recipients with marked elevation of hepatic transaminase...

Hepatitis E virus (HEV) infection among pregnant women is severe, often leading to fulminant hepatic failure and death, with mortality rates up to 15-25%. Studies suggest that differences in genotypes/subgenotypes, hormonal and immunological changes during pregnancy may contribute to the severe consequences for pregnant women with HEV. Although the increased mortality among pregnant women predominantly is seen in developing countries where genotype 1 is endemic, there are also large differences in mortality among pregnant women within these countries...

BACKGROUND: Gestational alloimmune liver disease, a form of profound liver failure in the newborn, is the main underlying cause of the entity formerly known as neonatal hemochromatosis. Antepartum maternal intravenous immunoglobulin (IVIG) has been shown to prevent gestational alloimmune liver disease, which otherwise has a recurrence risk above 90% in subsequent pregnancies. CASE: A 30-year-old woman, gravida 3 para 0120, presented early in gestation. Her previous pregnancy had been complicated by fetal growth restriction, oligohydramnios, and ultimately fatal fulminant neonatal liver failure...

The clinical manifestations of hepatitis E are similar to those of other types of viral hepatitis. While acute hepatitis E is usually self-limited, pregnant women and chronic liver disease patients suffering from acute hepatitis E usually present with severe clinical manifestations that may develop into fulminant hepatic failure. Chronic HEV infection is typically only seen in organ transplant patients; most HEV cases are asymptomatic and rarely display jaundice, fatigue, abdominal pain, fever, fatigue, or ascites...

Purpose. A 66-year-old man who presented with coma was found to have isolated severe hyperammonemia and diagnosed with a late-onset urea-cycle disorder. He was treated successfully and had full recovery. Methods. We report a novel case of noncirrhotic hyperammonemia and review the literature on this topic. Selected literature for review included English-language articles concerning hyperammonemia using the search terms "hyperammonemic encephalopathy", "non-cirrhotic encephalopathy", "hepatic encephalopathy", "urea-cycle disorders", "ornithine transcarbamylase (OTC) deficiency", and "fulminant hepatic failure"...

Physicians and Internists in India have tended to brush under the carpet legal issues affecting their profession. Of concern to all Physicians is the judgment in a recent case where the NCDRC has stated that if MD Medicine Physicians write Physician & Cardiologist on their letterhead it is Quackery. What is MD Medicine degree holder in India qualified and trained to treat ? These are issues which need debate and that can only be initiated once we recognize that there is a problem. Either an MD Medicine is a cardiologist or he is not...

Hepatitis B virus (HBV) reactivation during chemotherapy is a major concern and is widely reported, particularly in association with hematological malignancies and lymphomas. While lung cancer ranks first in incidence and mortality worldwide, HBV reactivation has been largely overlooked in this disease. As regards small-cell lung cancer (SCLC), HBV reactivation has rarely been reported. We herein report the case of a hepatitis B surface antigen-seropositive SCLC patient in whom HBV was reactivated during the course of chemotherapy, despite preemptive use of lamivudine...

A novel animal model involving chimeric mice with humanized livers established via human hepatocyte transplantation has been developed. These mice, in which the liver has been repopulated with functional human hepatocytes, could serve as a useful tool for investigating human hepatic cell biology, drug metabolism, and other preclinical applications. One of the key factors required for successful transplantation of human hepatocytes into mice is the elimination of the endogenous hepatocytes to prevent competition with the human cells and provide a suitable space and microenvironment for promoting human donor cell expansion and differentiation...

: The interferon (IFN) response to viral pathogens is critical for host survival. In humans and mouse models, defects in IFN responses can result in lethal herpes simplex type-1 (HSV-1) infections, usually from encephalitis. Although rare, HSV-1 can also cause fulminant hepatic failure which is often fatal. While herpes simplex encephalitis has been extensively studied, HSV-1 generalized infections and subsequent acute liver failure are less well understood. We previously demonstrated that IFNαβγR(-/-) mice are exquisitely susceptible to liver infection following corneal infection with HSV-1...

An 8-year-old Holsteiner gelding was presented for evaluation of anorexia, obtundation, icterus, and mild colic signs of 48 hours duration. History, physical examination, and initial diagnostics were suggestive of hepatic disease and encephalopathy. Microcystin toxicosis was suspected based on historical administration of a cyanobacteria supplement, associated serum biochemistry abnormalities, and characteristic histopathological changes. Microcystin contamination was confirmed in both supplement containers fed to the horse...

Mitochondrial DNA (mtDNA) depletion syndrome manifests as diverse early-onset diseases that affect skeletal muscle, brain and liver function. Mutations in several nuclear DNA-encoded genes cause mtDNA depletion. We report on a patient, a 3-month-old boy who presented with hepatic failure, and was found to have severe mtDNA depletion in liver and muscle. Whole-exome sequencing identified a homozygous missense variant (c.544C > T, p.R182W) in the accessory subunit of mitochondrial DNA polymerase gamma (POLG2), which is required for mitochondrial DNA replication...

Fulminant hepatic failure is a life-threatening disease which occurs in patients without preexisting liver disease. Nowadays, there is no ideal therapeutic tool in the treatment of fulminant hepatic failure. Recent studies suggested that a novel technology termed CRISPR/Cas9 may be a promising approach for the treatment of fulminant hepatic failure. In this project, we have designed single chimeric guide RNAs specifically targeting the genomic regions of mouse Fas gene. The in vitro and in vivo effects of sgRNAs on the production of Fas protein were examined in cultured mouse cells and in a hydrodynamic injection-based mouse model, respectively...

Acute liver failure, also known as fulminant hepatic failure (FHF), embraces a spectrum of clinical entities characterized by acute liver injury, severe hepatocellular dysfunction, and hepatic encephalopathy. Cerebral edema and intracranial hypertension are common causes of mortality in patients with FHF. The management of patients who present acute liver failure starts with determining the cause and an initial evaluation of prognosis. Regardless of whether or not patients are listed for liver transplantation, they should still be monitored for recovery, death, or transplantation...

BACKGROUND: Mesenchymal stromal cells (MSCs) are multipotent and have great potential in cell therapy. Previously we reported the differentiation potential of human MSCs into hepatocytes in vitro and that these cells can rescue fulminant hepatic failure. However, the conventional static culture method neither maintains growth factors at an optimal level constantly nor removes cellular waste efficiently. In addition, not only is the duration of differentiating hepatocyte lineage cells from MSCs required to improve, but also the need for a large number of hepatocytes for cell therapy has not to date been addressed fully...

Liver disease in pregnancy can be classified as predating, co-incidental or unique to pregnancy. Medications are often overlooked as a significant cause of liver disease. We present the case of a 39-year-old patient who presented at 20 weeks with jaundice, elevated liver enzymes, and abnormal liver function progressing eventually to fulminant hepatic failure. The patient was on methyldopa and labetalol from 12 weeks' gestational age. Liver biopsy was consistent with drug-induced liver injury. Both methyldopa and labetalol have been associated with hepatotoxicity including liver failure...
