View clinical trials related to Alcoholic Hepatitis.
Filter by:Alcoholic hepatitis (AH) is a florid presentation of alcoholic liver disease characterized by liver failure in the context of recent and heavy alcohol consumption. The condition carries a high fatality risk; patients with severe AH have a 30% mortality rate at 90 days after presentation. Currently there is no effective treatment for severe alcoholic hepatitis. Based on our current understanding of the disease pathogenesis IL-1 (interleukin) is a key mediator of hepatic inflammation responsible for metabolic disturbances, fibrogenesis stellate cell activation and consequently portal hypertension. Canakinumab is a licensed monoclonal antibody inhibitor of IL-1 and may consequently reverse the adverse effects of the cytokine in patients with this disorder. Therefore, the main objective of the ISAIAH trial is to explore the potential benefits of the IL-1β antibody, Canakinumab (solution for injection), in the treatment of alcoholic hepatitis. ISAIAH is a multicentre, double blind, randomized (1:1), placebo controlled trial. The trial will follow patients up for 90 days and will be conducted in centres across the United Kingdom. Twenty-six patients will be recruited to each arm of the trial: total 52 patients.
Alcoholic hepatitis is related to very high mortality rate. About 40% of the patients are 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 has 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 this studies there was a survival benefit with the use of G-CSF. Therefore we plan to study the safety and efficacy of G-CSF in the patients with alcoholic hepatitis.
Approximately 50% of patients admitted for severe AH will have spontaneous improvement of liver function before initiation of therapy (ie decrease in mDF between hospital admission and initiation of steroids). These patients have a better prognosis than patients without spontaneous improvement of liver function. It has never been demonstrated that corticosteroids improve survival in severe AH patients with spontaneous improvement of liver function. Our hypothesis is that severe AH patients with spontaneous improvement of liver function represent a group who could most benefit from steroids
Recent data have suggested that monocyte oxidative burst defect is associated with the development of infection in patients with severe alcoholic hepatitis. One report found reduced 28 day mortality in patients treated with N-acetylcysteine combined with prednisolone when compared to prednisolone alone. The current study seeks to reveal whether the mechanism by which NAC reduces susceptibility to infection is through improvement of phagocyte oxidative burst.

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 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 NAC plus G-CSF in patient with severe alcoholic hepatitis. Therefore we plan to study the safety and efficacy of combination therapy of G-CSF and NAC in the patients with alcoholic hepatitis.
