Clinical Trial of Pentoxifylline in Patient With Cirrhosis

Official Title: “Clinical Trial of Pentoxifylline Administration Versus Placebo on Survival in Patients With Cirrhosis and Severe Liver Failure”

In patients with cirrhosis and liver failure, pro-inflammatory cytokines (TNF alpha) might be responsible of severe complications and death. Thus, the prevention of cytokine production should prevent complications and mortality.

The aim of this study is to study the 2 months survival rate in patients with severe cirrhosis (Child-Pugh C) with pentoxifylline - an inhibitor of cytokine production. The 6 month mortality, the proportion of transplanted patients, the occurrence of complications (bacterial infection, renal failure, hepatic encephalopathy and gastrointestinal bleeding), plasma cytokine levels and fibrotest - a marker of fibrosis - will be also studied. This is a multicenter double blind randomized trial with a placebo.

All adult patients with severe cirrhosis might be randomized after written consent. Patients with severe carcinoma, intolerance or contraindication to pentoxifylline will not be included. Patients receive either pentoxifylline or placebo 3 times a day for 6 months.

Three hundred and forty two patients are necessary to decrease mortality rate by 50% at 2 months in a beta risk of 10% and an alpha risk of 5%. Patients will be seen every month.
