Type 2 diabetes (T2DM) is a complex disease linked to pancreatic beta-cell failure and insulin resistance. Current antidiabetic treatment regimens for T2DM include insulin sensitizers and insulin secretagogues. We have previously demonstrated that leptolide, a member of the furanocembranolides family, promotes pancreatic beta-cell proliferation in mice. Considering the beneficial effects of leptolide in diabetic mice, in this study, we aimed to address the capability of leptolide to improve insulin resistance associated with the pathology of obesity...

OBJECTIVES: Presentation as autoimmune acute liver failure (AI-ALF) and seronegative autoimmune liver disease (SN-AILD) represents two uncommon variants of AILD. We compared the clinical profile and outcome of AI-ALF with autoimmune-non-acute liver failure (AI-non-ALF) and also SN-AILD with seropositive autoimmune liver disease (SP-AILD). MATERIALS AND METHODS: Children managed as AI-ALF and AI-non-ALF including SN-AILD and SP-AILD were enrolled and compared. AI-non-ALF was diagnosed by simplified diagnostic criteria and AI-ALF by Pediatric Acute Liver Failure Study Group criteria with positive autoantibody, exclusion of other etiologies, elevated immunoglobulin G and histology when available...

Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration...

We present a case of a 63-year-old male who had travelled from South India to United Kingdom (UK) visiting relatives. He had developed episodes of diarrhea, vomiting and fevers while travelling and on assessment in hospital, mild abdominal distension was noted with rapid deterioration to hypovolemic shock. Initial blood test showed a low platelet count with deranged liver function tests (LFTs). It was noted that during admission to intensive care unit (ICU), blood continued to ooze from a previous surgical laparoscopy wound, central and arterial line access sites...

BACKGROUND & AIMS: Infections are life threatening to patients with acute decompensation and acute-on-chronic liver failure (AD/ACLF). Patients with AD/ACLF have prostaglandin E2-mediated immune suppression, which can be reversed by administration of albumin; infusion of 20% human albumin solution (HAS) might improve outcomes of infections. We performed a feasibility study to determine optimal trial design, assess safety, and validate laboratory assessments of immune function to inform design of a phase 3 trial...

Heat illness remains a large medical burden for militaries around the world. Mitigating the incidence as well as the complications of heat illness must remain on the forefront of operational planning when operating in hot environments. We report the case of a 27-year-old male U.S. Marine who sustained a heat-related illness resulting in fulminant liver failure and permanent disability. The patient was transferred from the field to a civilian hospital. On hospital day 5, liver failure was identified. The patient was transferred to a transplant center, where he successfully received a liver transplant...

Bacterial infections are an important cause of mortality in liver failure. However, the type of infection, predictors of infection, and their impact on outcomes in patients with acute-on-chronic liver failure (ACLF) are limited.A total of 389 patients with ACLF were admitted in this retrospective, corhort study. Once admitted, clinical data including first infection site, type (community-acquired, healthcare-associated, or nosocomial), and second infection occurrence during hospitalization were collected. The outcome was mortality within 90 days...

Acute liver failure (ALF) is an acute medical emergency which carries high mortality without liver transplantation. Various hepatotropic viruses, drug induced liver injury, auto immune hepatitis, and metabolic liver diseases are the commonly implicated etiologic agents. Liver involvement in dengue hemorrhagic fever (DHF) is quite common, but acute liver failure is its rare complication. Neurological complications are also commonly seen in DHF. Ateenage girl presented with high grade fever and subconjunctival hemorrhage, and later developed jaundice due to acute liver failure...

Hepatic ischemia/reperfusion (I/R) injury is a common pathophysiological process that occurs following liver surgery, which is associated with oxidative stress, and can cause acute liver injury and lead to liver failure. Recently, the development of drugs for the prevention of hepatic I/R injury has garnered interest in the field of liver protection research. Previous studies have demonstrated that [D‑Ala2, D‑Leu5]‑Enkephalin (DADLE) exerts protective effects against hepatic I/R injury. To further clarify the specific mechanism underlying the effects of DADLE on hepatic I/R injury, the present study aimed to observe the effects of various doses of DADLE on hepatic I/R injury in mice...

Chronic alcohol related liver disease is characterized by a cascade of events defined as follows: steatosis, steatohepatitis/steatofibrosi, cirrhosis and hepatocellular carcinoma. On one of these histologic patterns may overlap acute alcoholic hepatitis (AAE) (mild, moderate, severe). Severe AAE can cause a severe clinical picture: jaundice with a duration of less than three months, jaundice in the first decompensation event, serum bilirubin higher than 5 mg/dL, ratio AST/ALT >2:1, AST less than 500 IU/L ALT <300 IU/L, neutrophil leukocytosis and increased GGT...

Intraperitoneal transplantation of hepatocyte microbeads is an attractive option for the management of acute liver failure. Encapsulation of hepatocytes in alginate microbeads supports their function and prevents immune attack of the cells. Establishment of banked cryopreserved hepatocyte microbeads is important for emergency use. The aim of this study was to develop an optimized protocol for cryopreservation of hepatocyte microbeads for clinical transplantation using modified freezing solutions. Four freezing solutions with potential for clinical application were investigated...

Urea cycle disorders (UCDs) are inborn errors of metabolism of the nitrogen detoxification pathway and encompass six principal enzymatic deficiencies. The aging of UCD patients leads to a better knowledge of the long-term natural history of the condition and to the reporting of previously unnoticed manifestations. Despite historical evidence of liver involvement in UCDs, little attention has been paid to this organ until recently. Hence, we reviewed the available scientific evidence on acute and chronic liver dysfunction and liver carcinogenesis in UCDs and discuss their pathophysiology...

Liver transplant (LT) is often the only life-saving therapeutic option for patients with acute liver failure (ALF) (i.e. without prior liver disease) and for acute-on-chronic liver failure (ACLF). With the progressive introduction of the model for end-stage liver disease (MELD) score in liver transplantation allocation algorithms (since 2007 in France), a new paradigm has begun to emerge based on the idea of prioritizing transplant allocations to patients who are more acutely ill and with the highest MELD scores...

Deficient ADAM metalloproteinase with thrombospondin type-1 motif, member 13 (ADAMTS13) activity (ADAMTS13:AC) results in the accumulation of unusually large von Willebrand factor multimers (UL-VWFM) and causes microcirculatory disturbances and multiple organ failure, while endotoxins trigger the activation of a coagulation cascade. The objective of the present study was to explore the role of ADAMTS13 in endotoxemia in patients with acute liver failure (ALF). Plasma concentrations of endotoxin and cytokines, including interleukin (IL)-6 and IL-8, and activity of the plasma ADAMTS13 inhibitor were determined, along with ADAMTS13:AC, the VWF antigen (VWF:Ag) and UL-VWFM, in 27 patients with acute hepatitis (AH), 11 patients with ALF, and 10 healthy controls...

Extracorporeal membrane oxygenation (ECMO) has been successfully used for the treatment of patients with respiratory failure due to severe infections. Though rare, parasites can also cause severe pulmonary disease. Tapeworms of the genus Echinococcus give rise to the development of cystic structures in the liver, lungs and other organs. Acute cyst rupture leads to potentially life-threatening infection, and affected patients may deteriorate rapidly. We describe the case of a young woman from Bulgaria who was admitted to hospital with severe dyspnoea, progressive chest pain and haemoptysis...

Ornithine transcarbamylase deficiency (OTCD) is an X-linked urea cycle disorder with variable expressivity in heterozygous females. While liver function testing is often abnormal in patients with OTCD, liver failure is uncommon on presentation. A 13-month-old female with no significant past medical history presented with irritability, right arm weakness, and decreased appetite. Initial workup revealed hepatic dysfunction with an INR of 3.4, ammonia level of 75 μmol/L, and abnormal brain MRI with gyral edema with restricted diffusion, and patchy signal abnormality in basal ganglia...

The role of hepatic NK cells in the pathogenesis of HCV-associated hepatic failure is incompletely understood. In this study, we investigated the effect of HCV on ConA-induced immunological hepatic injury and the influence of HCV on hepatic NK cell activation in the liver after ConA administration. An immunocompetent HCV mouse model that encodes the entire viral polyprotein in a liver-specific manner based on hydrodynamic injection and φC31o integrase was used to study the role of hepatic NK cells. Interestingly, the frequency of hepatic NK cells was reduced in HCV mice, whereas the levels of other intrahepatic lymphocytes remained unaltered...
