Alcoholic Hepatitis (alcoholic + hepatitis)
Kinds of Alcoholic Hepatitis Selected AbstractsPotential Role of Enhanced Cytokinemia and Plasma Inhibitor on the Decreased Activity of Plasma ADAMTS13 in Patients With Alcoholic Hepatitis: Relationship to EndotoxemiaALCOHOLISM, Issue 2010Masatoshi Ishikawa Background:, Deficiency of ADAMTS13 (adisintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13) results in an increase in unusually large von Willebrand factor multimer (UL-VWFM) of the plasma and finally causes microcirculatory disturbance. Our previous study demonstrated that the imbalance of increased UL-VWFM over decreased ADAMTS13 activity may contribute to the development of multiorgan failure in patients with alcoholic hepatitis (AH). The aim of this study was to explore the potential mechanism to reduce the activity of plasma ADAMTS13. Methods:, Plasma cytokine levels including interleukin (IL)-6, IL-8, and tumor necrosis factor-, (TNF-,), plasma endotoxin concentration, and the plasma inhibitor against ADAMTS13 were determined together with ADAMTS13 activity, VWF antigen (VWF:Ag), and UL-VWFM in 24 patients with AH and 5 patients with severe alcoholic hepatitis (SAH). Results:, The concentrations of IL-6, IL-8, and TNF-, on admission were significantly higher in patients with SAH than in those with AH and controls. The ADAMTS13 activity concomitantly decreased, and the VWF:Ag progressively elevated with increasing concentrations of these cytokines from normal range to over 100 pg/ml. Plasma endotoxin concentration was markedly higher in patients with SAH (mean 52.3 pg/ml) and AH (21.7 pg/ml) than in controls (7.9 pg/ml). The endotoxin concentration inversely correlated with ADAMTS13 activity and was higher in patients with UL-VWFM than those without. The inhibitor was detected in 4 patients with SAH (0.9 to 2.1 BU/ml) and 6 patients with AH (0.5 to 1.6 BU/ml). Patients with the inhibitor showed lower functional liver capacity, higher endotoxin concentration, and marked inflammatory signs than those without. At the recovery stage, the ADAMTS13 activity increased to normal range, the VWF:Ag decreased, and the UL-VWFM disappeared with the decrease in the concentrations of cytokines and endotoxin, and the disappearance of the inhibitor. Conclusion:, Decreased ADAMTS13 activity and increased VWF:Ag could be induced not only by pro-inflammatory cytokinemia, but also by its inhibitor, both of which may be closely related to enhanced endotoxemia in patients with AH and SAH. [source] Treatment of alcoholic hepatitisJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 4 2002Jacquelyn J Maher Abstract, Alcoholic hepatitis is a common disease with an overall 1-year mortality of 20%. Although the classical treatment for alcoholic hepatitis is abstinence, in some individuals abstinence alone is inadequate to promote survival and recovery. This is particularly true of patients with severe alcoholic hepatitis, who are identified by jaundice, coagulopathy and neutrophilia. Within the last two decades, several agents have been examined as treatments for alcoholic hepatitis and cirrhosis. They have targeted several key processes in the pathophysiology of alcoholic liver disease, including hypermetabolism, inflammation, cytokine dysregulation and oxidant stress. The compounds that offer the greatest survival benefit to patients with severe alcoholic hepatitis are corticosteroids. Several groups have reported excellent results with corticosteroids, but positive results are not uniform, and there remains some controversy over their efficacy. Even if corticosteroids are beneficial for alcoholic hepatitis, they are not recommended for all patients at risk. Consequently, other agents are being tested that have broader applicability to individuals with contraindications to steroids. In this regard, pentoxifylline shows some promise, as does enteral feeding with medium chain triglycerides. Independent efforts are also being directed toward treatment of chronic alcoholic liver disease and alcoholic cirrhosis. Anti-oxidants have received the greatest attention; drugs such as S -adenosyl-methionine may be of benefit. This and others are under active study. © 2002 Blackwell Publishing Asia Pty Ltd [source] Liver Disease in Heavy Drinkers With and Without Alcohol Withdrawal SyndromeALCOHOLISM, Issue 1 2004E. Barrio Abstract: Background: Withdrawal syndrome is a hallmark of alcohol dependence. The characteristics of alcohol consumption, closely related to dependence, could influence the development of alcoholic liver disease. The study aimed to investigate if patients with severe alcohol withdrawal syndrome have a peculiar profile of liver disease. Methods: The study included 256 heavy drinkers (aged 19,75 years, 70.3% males) admitted to an Internal Medicine Department. Patients admitted for complications of liver disease were not included. Severe alcohol withdrawal syndrome (seizures, disordered perceptions, or delirium) developed in 150 patients (58.6%). Alcohol consumption (daily quantity, duration, and pattern [regular or irregular]) was assessed by questionnaire. Liver biopsy was performed in all cases. Results: Patients with alcohol withdrawal syndrome showed a lower prevalence of liver cirrhosis and a higher prevalence of alcoholic hepatitis than patients without it. The negative association of alcohol withdrawal syndrome with liver cirrhosis persisted after we adjusted for sex, daily intake, duration, and pattern of alcohol consumption. Alcoholic hepatitis was independently associated with the irregular pattern of alcohol consumption, which was closely associated with severe alcohol withdrawal syndrome. Conclusions: The profile of liver injury is different in heavy drinkers who develop and who do not develop a severe alcohol withdrawal syndrome when admitted to the hospital.

COHEN Summary Background, Alcoholic hepatitis is a severe, cholestatic liver disease occurring in patients with alcohol abuse. Mortality is substantial; however, therapies may improve clinical outcomes. Aim, To provide an updated review of the epidemiology, diagnosis, staging and treatment of alcoholic hepatitis. Methods, A MEDLINE literature search was performed to identify pertinent articles. Relevant clinical abstracts were also reviewed. Results, Severe alcoholic hepatitis occurs in a small fraction of patients who abuse alcohol. The 28-day mortality ranges from 30% to 50% in most series. Diagnosis is generally based on clinical features, with a limited role for liver biopsy. Beneficial treatment options include alcohol abstinence and nutritional therapy. Despite variable results in clinical trials, corticosteroids and pentoxifylline appear to provide moderate survival benefit. Anti-tumour necrosis factor agents and antioxidants have not proven beneficial, and should be limited to clinical trials. Liver transplant is not a frequent option given the active or recent alcohol use. Conclusions, Severe alcoholic hepatitis is a clinically-diagnosed condition associated with significant mortality. Alcohol abstinence and nutritional therapy have been associated with improved clinical parameters and should be considered in all patients. Corticosteroid therapy and pentoxifylline therapy appear to show moderate survival benefit and should be considered as first-line therapeutic agents. [source] Autoantibodies in alcoholic liver diseaseADDICTION BIOLOGY, Issue 2 2000Ian G. McFarlane Despite many decades of research, the reasons why only a relatively small proportion of individuals who consume excessive quantities of alcohol develop clinically significant liver disease remain unknown. The association with features of autoimmune diseases, including hypergammaglobulinaemia, circulating autoantibodies, inheritance of certain immunogenetic (HLA) markers and response to corticosteroid therapy in some patients has led to a persistent impression that altered immune regulation with a relative loss of self-tolerance underlies susceptibility to the development of the more severe forms of alcoholic liver disease (alcoholic hepatitis and/or cirrhosis). However, review of the data from the numerous studies that have been conducted over the past 30 years fails to reveal sufficiently convincing evidence that autoimmunity plays a primary role in alcohol-related liver damage. In particular, most of the wide range of circulating autoantibodies that have been reported in patients are found mainly at low titres, are not confined to those with severe liver injury, and are probably more likely to be a response to the hepatic insult than causally related to liver damage. Additionally, an association with various HLA phenotypes has not been confirmed by meta-analysis. Interpretation is complicated by evidence that alcohol may have direct effects on some components of the immune system but, if there is an immunogenetic basis for alcoholic liver disease, the present evidence suggests that this might be related more to cytokine gene polymorphisms than to a predisposition to autoimmunity per se. [source] The interleukin-17 pathway is involved in human alcoholic liver disease,,HEPATOLOGY, Issue 2 2009Arnaud Lemmers Immune dysregulations in alcoholic liver diseases are still unclear, especially regarding alcoholic hepatitis inflammatory burst. Interleukin-17 (IL-17) is known to enhance neutrophil recruitment. We studied the IL-17 pathway in alcoholic cirrhosis and alcoholic hepatitis. Patients with alcoholic liver disease were compared with patients with chronic hepatitis C virus (HCV) infection or autoimmune liver disease and with healthy controls. IL-17 plasma levels and peripheral blood mononuclear cell secretion were assessed by enzyme-linked immunosorbent assay (ELISA) and T cell phenotype by flow cytometry. IL-17 staining and co-staining with CD3 and myeloperoxidase were performed on liver biopsy specimens. IL-17 receptor expression was studied on liver biopsies and in human hepatic stellate cells as well as their response to recombinant IL-17 by chemotaxis assays. IL-17 plasma levels were dramatically increased in alcoholic liver disease patients. Peripheral blood mononuclear cells of patients with alcoholic liver disease produced higher amounts of IL-17, and their CD4+ T lymphocytes disclosed an IL-17,secreting phenotype. In the liver, IL-17,secreting cells contributed to inflammatory infiltrates in alcoholic cirrhosis, and alcoholic hepatitis foci disclosed many IL-17+ cells, including T lymphocytes and neutrophils. In alcoholic liver disease, liver IL-17+ cells infiltrates correlated to model for end-stage liver disease score, and in alcoholic hepatitis to modified discriminant function. IL-17 receptor was expressed in alcoholic liver disease by hepatic stellate cells, and these cells recruited neutrophils after IL-17 stimulation in a dose-dependent manner through IL-8 and growth related oncogen , (GRO-,) secretion in vitro. Conclusion: Human alcoholic liver disease is characterized by the activation of the IL-17 pathway. In alcoholic hepatitis, liver infiltration with IL-17,secreting cell infiltrates is a key feature that might contribute to liver neutrophil recruitment. (Clinical trials number NCT00610597). (HEPATOLOGY 2009;49:646,657.) [source] Increasing dimethylarginine levels are associated with adverse clinical outcome in severe alcoholic hepatitis,HEPATOLOGY, Issue 1 2007Rajeshwar P. Mookerjee Previous studies suggest reduced hepatic endothelial nitric oxide synthase activity contributes to increased intrahepatic resistance. Asymmetric dimethylarginine (ADMA), an endogenous nitric oxide synthase inhibitor, undergoes hepatic metabolism via dimethylarginine-dimethylamino-hydrolase, and is derived by the action of protein-arginine-methyltransferases. Our study assessed whether ADMA, and its stereo-isomer symmetric dimethylarginine (SDMA), are increased in alcoholic hepatitis patients, and determined any relationship with severity of portal hypertension (hepatic venous pressure gradient measurement) and outcome. Fifty-two patients with decompensated alcoholic cirrhosis were studied, 27 with acute alcoholic hepatitis and cirrhosis, in whom hepatic venous pressure gradient was higher (P = 0.001) than cirrhosis alone, and correlated with ADMA measurement. Plasma ADMA and SDMA were significantly higher in alcoholic hepatitis patients and in nonsurvivors. Dimethylarginine-dimethylamino-hydrolase protein expression was reduced and protein-arginine-methyltransferase-1 increased in alcoholic hepatitis livers. ADMA, SDMA and their combined sum, which we termed a dimethylarginine score, were better predictors of outcome compared with Pugh score, MELD and Maddrey's discriminant-function. Conclusion: Alcoholic hepatitis patients have higher portal pressures associated with increased ADMA, which may result from both decreased breakdown (decreased hepatic dimethylarginine-dimethylamino-hydrolase) and/or increased production. Elevated dimethylarginines may serve as important biological markers of deleterious outcome in alcoholic hepatitis. (HEPATOLOGY 2007;45:62,71.) [source] Early change in bilirubin levels is an important prognostic factor in severe alcoholic hepatitis treated with prednisoloneHEPATOLOGY, Issue 6 2003Philippe Mathurin M.D. Early identification of patients with severe (discriminant function ,32) biopsy-proven alcoholic hepatitis (AH) who are not responding to corticosteroids would be clinically relevant. Our goal was to develop simple criteria that will help physicians to promptly identify nonresponders to corticosteroids. A total of 238 patients were included. We used 6 months survival as an end point because of the rule requiring 6 months for listing alcoholic patients for transplantation. Overall survival at 1 and 6 months was 85% ± 2.3% and 64.3% ± 3.3%, respectively. An early change in bilirubin levels (ECBL) at 7 days (defined as bilirubin level at 7 days lower than bilirubin level on the first day of treatment) was observed in 73% of patients. At 7 days, in patients with ECBL, bilirubin decreased (84 ± 75 ,mol/L [4.94 ± 4.40 mg/dL]), whereas it increased in patients without ECBL (76.5 ± 77 ,mol/L [4.50 ± 4.54 mg/dL], P < .0001). Ninety-five percent of patients with ECBL continued to have improved liver function during treatment. At 6 months, survival of patients with ECBL was significantly higher than that of patients without ECBL, 82.8% ± 3.3% versus 23% ± 5.8%, P < .0001. On multivariate analysis, ECBL, discriminant function and creatinine were independent prognostic variables, and ECBL had the most important prognostic value. In conclusion, ECBL is a very simple predictive factor for identifying nonresponders. A recommendation to discontinue corticosteroids after 7 days in patients without ECBL, suggested by our results, awaits additional confirmation.

[source] Understanding and Treating Patients With Alcoholic Cirrhosis: An UpdateALCOHOLISM, Issue 7 2009Giovanni Addolorato Alcoholic cirrhosis represents the terminal stage of alcoholic liver disease (ALD) and one of the main causes of death among alcohol abusers. The aim of this review was to provide an update on alcoholic cirrhosis, with an emphasis on recent findings. Increased alcohol consumption in developing countries is expected to increase cirrhosis mortality. There is a need, therefore, to develop new approaches to the prevention of ALD, including more attention to co-factors that may increase risk of ALD (i.e., obesity and diabetes, chronic HCV infection, and smoking). Furthermore, a better understanding of the pathological mechanisms on the basis of alcohol cirrhosis represents a cornerstone in order to develop new pharmacological treatments. Inflammatory and immune responses along with oxidative stress and alterations in adipokine secretion might contribute in different ways to the evolution of alcohol-induced fibrosis/cirrhosis. As of this date, patients with severe alcoholic hepatitis with a Maddrey Discriminant Factor (MDF) 32 should be offered pentoxifylline and/or corticosteroids unless contraindications exist. For ambulatory patients, S-adenosylmethionine (SAMe) may be considered in a motivated patient with nutritional support. Current studies do not support use of anti-tumor necrosis factor (TNF)-alpha antibody. Finally, achieving total alcohol abstinence should represent the main aim in the management of patients affected by any stage of cirrhosis. In the last decades, several drugs able to increase abstinence and prevent alcohol relapse have been evaluated and some of them have obtained approval for alcohol dependence. Patients with alcoholic cirrhosis; however, are usually excluded from such treatments. A recent study demonstrated the efficacy and safety of baclofen in inducing and maintaining alcohol abstinence in cirrhotic alcohol-dependent patients with cirrhosis. All together the information available suggests the need of a multimodal approach in the clinical management of these patients. [source] Serum Levels of Tissue Polypeptide Specific Antigen Are Correlated With Hepatocyte Cytokeratin Expression in Alcoholic Liver DiseaseALCOHOLISM, Issue 9 2004A Gonzalez-Quintela Background: Serum levels of the tumor marker tissue polypeptide specific antigen (TPS, cytokeratin 18 fragments) are increased in patients with alcoholic liver disease, particularly in cases of alcoholic hepatitis. Mallory bodies, characteristic of alcoholic hepatitis, are cytokeratin 8 and 18 aggregates. The study was aimed at investigating the possible relationship of serum TPS levels with hepatocyte cytokeratin expression in patients with alcoholic liver disease. Methods: Twenty-four patients with alcoholic liver disease were studied. Immunohistochemical staining for cytokeratins 8 and 18 was performed in liver specimens by means of CAM 5.2 monoclonal antibody. The number of hepatocytes containing CAM 5.2-reactive cytokeratin inclusions was compared with serum TPS levels. Main Results and Conclusions: The vast majority of alcoholics (95%) showed increased (>100 units/liter) serum TPS levels. Serum TPS levels were significantly correlated with the number of hepatocyte cytokeratin inclusions. Serum TPS levels can predict hepatocyte cytokeratin expression in patients with alcoholic liver disease.

YILMAZ Summary Background, Biomarkers hold great promise for detecting chronic liver disease without the use of liver biopsy. Aim, To review the usefulness of cytokeratin (CK) 18 fragments, a marker of hepatocyte apoptosis, to predict the presence of chronic liver injury. Methods, Available literature identified from PubMed was reviewed. Results, Levels of CK18 fragments have been shown to be elevated in hepatocellular carcinoma, viral hepatitis, alcoholic hepatitis, nonalcoholic fatty liver disease and cholestatic liver disease. In the setting of nonalcoholic fatty liver disease, CK18 fragments may distinguish nonalcoholic steatohepatitis from simple fatty liver. Conclusions, Undoubtedly, the most promising application of CK18 fragments is currently in nonalcoholic fatty liver disease, and especially for distinguishing patients with nonalcoholic steatohepatitis vs. those with simple steatosis. Further investigations and technical improvements are required to cross the boundary from research to the clinical application of CK18 fragments as a marker of chronic liver disease.

[source] How to modulate inflammatory cytokines in liver diseasesLIVER INTERNATIONAL, Issue 9 2006Herbert Tilg Abstract: Most acute and chronic liver diseases are characterized by inflammatory processes with enhanced expression of various pro- and anti-inflammatory cytokines in the liver. These cytokines are the driving force of many inflammatory liver disorders often resulting in fibrosis and cirrhosis. Severe alcoholic hepatitis is a prototypic tumor necrosis factor-, (TNF-,)-associated disease. This knowledge has recently led to pilot studies with promising results investigating specific anti-TNF drugs such as infliximab or etanercept in the treatment of this disease, although a recently performed controlled French study did show a potential detrimental effect of this approach. Anti-TNF treatment strategies might also improve chronic hepatitis C infection as shown by one controlled trial using etanercept administered subcutaneously for 24 weeks. Furthermore, several case reports suggest that TNF-, neutralization is not harmful to patients chronically infected with this virus. In contrast, neutralization of TNF-, worsens and might even be associated with fatalities in chronic hepatitis B infection. Anti-inflammatory cytokines such as interleukin-10 (IL-10) have also been tried in patients with chronic liver diseases. Whereas IL-10 administered to patients with chronic hepatitis C virus infection shows indeed anti-inflammatory effects in the liver, it seems to act as a proviral agent thereby limiting its clinical utility. Another cytokine with major anti-inflammatory potential is the adipokine adiponectin, as its administration is beneficial in many experimental models of liver injury. Interference with cytokine pathways and/or administration of anti-inflammatory cytokines will be of major interest in the future therapy of many liver diseases. [source] Current management of alcoholic liver diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2004S. Tome Summary Alcoholic liver disease, including acute alcoholic hepatitis and alcoholic cirrhosis, is a major cause of morbidity and mortality in the Western world. Abstinence remains the cornerstone of management of all forms of alcoholic liver disease. Recent research, which has elucidated the mechanisms of alcohol-induced liver injury, offers the prospect of advances in the management of alcoholic liver disease. We review the most recent data on the efficacy of treatment of acute alcoholic injury, including nutritional support, corticosteroids, anti-inflammatory agents and antioxidants, and agents that are directed against the progression to fibrosis, such as colchicines, propylthiouracil and antioxidants. Although these therapies offer a tantalizing glimpse into a future that may include therapies that directly alter the process of injury and repair in the liver, none has been shown consistently to improve the course of alcoholic liver damage. Consequently, liver transplantation remains an ultimate option for selected patients with liver failure due to chronic alcoholic liver damage. [source] | ||||||||||||||||||||||
