Alcoholic Hepatitis Clinical Trial

Status Completed

Clinical Trial Summary

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.
