Filter by:Alcohol-associated hepatitis is a clinical syndrome distinct from steatohepatitis or liver cirrhosis. It is associated with high mortality and characterized by an absence of effective treatment, while corticosteroids, which are currently used as the first-line treatment are effective only in a subpopulation of patients and only on 28-days survival - their effect on survival does not last beyond this interval. The proposed study is a complex exploratory study of alcohol-associated hepatitis with several epidemiology- and prognosis-related aims.
Alcoholic hepatitis, the most florid form of alcoholic liver disease, has a very high short-term mortality of up to 50% and no specific therapies are available other than steroids. Steroids also only show a limited utility in improving the short-term survival and boast no evidence of any long-term benefits. Additionally, only a small proportion of patients with alcoholic hepatitis are eligible to receive steroids. Thus, a large number of patients are either not eligible or do not respond to steroids and this group outnumbers those who do respond to steroids, leaving us without any specific therapeutic options for a majority of these individuals.[1] Even liver transplantation is not feasible in most cases due to the presence of sepsis or recent alcohol consumption and many ethical and logistic issues are involved despite the documented safety and survival benefits of early liver transplantation in patients with severe alcoholic hepatitis (SAH) not responding to medical management.[2,8] Therefore, newer, more effective, and nontransplant therapeutic options for managing severe alcoholic hepatitis are needed. TPE is expected to be an effective and well-tolerated bridge therapy in patients with severe alcoholic hepatitis of moderate severity not improving on SMT and without immediate prospects for liver transplantation.
Alcoholic hepatitis (AH) is a serious complication of alcoholic liver disease (ALD). The histological presentation of AH is characterized by neutrophilic lobular inflammation, macrovesicular steatosis, hepatocyte ballooning and necrosis and the presence of Mallory bodies. In cases of severe HA, defined by a modified Maddrey score of 32 or above, mortality at 1 month is estimated at between 10 and 50%. The only treatment to reduce early mortality is corticosteroid therapy. However, only 60% of patients respond to corticosteroids, and no benefit has been demonstrated on late mortality. Identifying new therapeutic targets is therefore a major challenge in this disease. Numerous pre-clinical studies and human data suggest the involvement of the intestinal microbiota in the pathogenesis of AH. Translocation of viable bacteria and microbial products from the digestive tract to the liver contributes to local and systemic inflammation, hepatocyte death and fibrogenesis. However, the intrahepatic microbial environment has never been characterized in HA. The study hypothesis is that the intrahepatic microbiota is modulated by bacterial translocation and is associated with clinical outcomes. The aim of this study is to determine the composition of the intrahepatic (obtained from transjugular liver biopsy), blood and fecal microbiota in patients with suspected severe AH from a monocentric prospective cohort in the Hepatology Department at Croix-Rousse Hospital (Lyon). Fifty consecutive patients with clinical suspicion of AH and indication for transjugular liver biopsy will be included. About thirty-five patients are expected in the confirmed AH group, and 15 in the group "alcoholic liver disease with no AH", based on data from the literature. The composition of the various microbiota will be determined by sequencing the 16S rRNA gene, and the results will be correlated with clinical data (corticosteroid sensitivity, overall survival, transplant-free survival, MELD score in particular) and histological data. This exploratory study will enable to analyze the intra-hepatic microbiota, and to study its link with intra-hepatic inflammation and the clinical course of patients with AH. The data generated by HepMAH will thus help identify potential new therapeutic targets linked to the gut microbiota, and provide a scientific basis for the development of therapeutic interventions targeting the microbiota in HA.
The goal of this study is to test MRG-001 (an experimental medication). The purpose of this trial is to assess the dose related safety, Pharmacokinetics, and Pharmacodynamics of MRG-001 in patients with severe alcoholic hepatitis (AH).
In humans, alcohol-related dysbiosis exists with a decrease in bacteroides. This dysbiosis is responsible for the breakdown of the intestinal barrier by a decrease in the synthesis of protective mucus, and some proteins involved in tight junctions or a decrease in defensin (Reg3b, Reg3g) which promotes bacterial growth and ultimately bacterial translocation. The microbiota of a patient with alcoholic hepatitis is different from that of a patient without alcoholic hepatitis. Acute alcoholic hepatitis has a severe prognosis and corticosteroids are the only first line therapy option, with better survival at 28 days versus placebo. However, mortality remains high at 30% at 3 months, which highlights the importance of seeking intestinal microbiota profile on treatment response. The determination of one or more intestinal microbiota signatures associated with the treatment response Corticosteroids plus FMT or Corticosteroids plus placebo will allow the clinician to have a simple and rapid test obtained in 16S RNA analysis to predict the therapeutic response and potentially the best treatment to adopt and to address medical and medico-economic stakes. The investigators will first characterize the alcohol-induced dysbiosis by a whole microbiota sequencing in the different groups. Specific bacterial species identify by DNA sequencing should be confirmed by qPCR of 16S rDNA to determine a fingerprint of sAH microbiota. Metabolic properties of intestinal microbiota, such as production of short chain fatty acids, will be analyzed by using HPLC. In the sAH group, evolution of intestinal microbiota will be observed by shotgun DNA sequencing between the day 0 and the day 7 of corticosteroids treatment. The analysis of sAH patients' microbiota (day 0) will allow us to obtain a non-responder profile to corticosteroids that can be used as a prognostic marker to use in the clinic. The deliverable is the bacterial fingerprint of the treatment response and its valuation is its use as a predictive tool of the response.
Severity of alcoholic hepatitis is defined by Maddrey's discriminant function, value of 32 or higher indicates severe alcoholic hepatitis that carries an adverse prognosis with one month mortality of 30%-50%. Prednisolone (40 mg/day) given orally should be considered to improve 28-day mortality in patients with severe AH. Abstinence is key to long-term survival. According to current protocol, we discontinue the treatment after 28 days but only 15 % patient is achieving the DF < 32 after 28 days of treatment. The aim of this study is to evaluate the role of extended low dose prednisolone (10mg) in achieving remission by day-90 in steroid responsive severe alcoholic hepatitis.
Alcohol-associated hepatitis (AH) is a life-threatening condition with high 90-days mortality (up to 40%) and limited treatment options. Previous studies have shown that decreased nutritional intake (less than 21 kcal/kg/day) is associated to a higher mortality compared to patients with a higher caloric intake. Additionally, it has been suggested that subjects with severe AH, should receive a high-protein diet, however, no specific trials have been carried out to address these questions. Thus, the investigators aim to compare nutritional interventions through a randomized controlled trial to assess if a strategy of peripheral parental nutrition (PPN) plus oral nutritional supplementation (ONS) improves outcomes in patients with severe AH. The investigators will compare standard oral intake, enhanced oral intake with IV fluid supplementation, and PPN plus ONS in patients admitted to hospital with severe AH. These results potentially will help guide practitioners on caloric benchmarks targets for patients with severe AH. This study will also assess specific risks and benefits of different nutritional interventions.
Alcoholic hepatitis (AH) is the most severe form of acute alcohol-related liver disease. Maddrey's discriminant function (mDF) >32 defines the severe form of AH, which is associated with a high mortality. Corticosteroid therapy (CS) represents the main medical treatment that may reduce short-term mortality. Lille score at day 7 assesses the therapeutic response to steroid therapy. At present, no parameters able to predict the response to steroid therapy have been highlighted. The mDF depends mainly on prothrombin time (PT). Aim of the present study was to evaluate if the PT value could predict the response to CS in severe AH (sAH).
Alcoholic hepatitis is related to very high mortality rate. About 40% of the patients died within first 6 months after the detection of the clinical syndrome. Therefore, it is very essential for proper diagnosis and early treatment . In response to acute or chronic liver damage, bone marrow derived stem cells can spontaneously populate liver and differentiate into hepatic cells. Animal and human studies suggested that injured hepatocyte may be replaced by pluripotent bone marrow cells. However, this hepatocyte repopulation is highly dependent on varieties of liver injury and therapeutic conditions. The studies have suggested Granulocyte-colony stimulating factors (G-CSF) can regenerate hepatocyte by fusing with hematopoietic cells, thereby enhancing the liver histology and survival rate. G-CSF is a cytokine capable to regulate a number of functions in neutrophils. In three recent studies mobilization of bone marrow stem cells induced by G-CSF was observed in patients with alcoholic hepatitis. In two of these studies there was a survival benefit with the use of G-CSF. Alcoholism leads to decrease in endogenous antioxidant potential. Alcoholic liver disease (ALD) patients show low endogenous antioxidants. Chronic ethanol consumption cause selective deficiency in the availability of reduced glutathione (GSH) in mitochondria has been reported. This is due to impaired functioning of GSH transporter from cytosol to mitochondrial matrix. The effect on glutathione replenishing potential by N-acetyl cysteine (NAC) can be used to reduce oxidative stress, which also has excellent safety profile. Therefore, NAC can be used for severe alcoholic hepatitis treatment due to its therapeutic potential factor. NAC also inhibit apoptosis and pro-inflammatory cytokine production. In a study high doses of intravenous N-acetyl cysteine therapy for 14 days conferred neither survival benefits nor early biological improvement in severe acute alcoholic hepatitis patients with adequate nutritional support.However, these results must be viewed with caution, since the study suffered from a lack of power. In a recent study, NAC and corticosteroids combination therapy benefits among patients with severe acute alcoholic hepatitis in 1 month survival, although the final outcome at 6 month survival was not improved. There are no studies on the use of combination therapy of 4 weeks of NAC plus G-CSF in patient with severe alcoholic hepatitis. Therefore the investigators plan to study the safety and efficacy of combination therapy of G-CSF and 4 weeks of NAC in the patients with alcoholic hepatitis.
Alcoholic hepatitis is a disease with a high mortality rate with few treatment options improving survival. Recently certain bacterial strains has been correlated to survival in patients with alcoholic hepatitis. In the BATTLE-trial the investigators will investigate if certain bacteria are correlated to decreased chance of survival in patients with alcoholic hepatitis.
