efficacy of plasma exchange therapy vs standard medical therapy in severe alcoholic hepatitis with high discriminant function

Conditions: Alcoholic Hepatitis

Summary: 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.

hypothesis:wehypothesise that the early treatment with therapeutic plasma exchange in alcoholic hepatitis patients might improve overall survival in carefully selected patients by removing cytokines, chemokines and toxic substances. aim: to compare transplant free survival between plasma exchange therapy and standard medical therapy in severe alcoholic hepatitis methodology: severe alcoholic hepatitis will be screened for the study and will be managed with smt initially will be assessed for steroid therapy if becomes ineligible counselled for liver transplant in view of high df and meld ,if there is no options of liver transplant in near future ,1 month will be given option for plex but it will be decided by randomisation whether he will get smt or plex.he/she will also be told that plex is not a approved treatment and is a trial therapy and they may or may not get benefited.patients patients who agreed to undergo plex then undergo randomisation between plex and smt and allocated in either group accordingly. control group will be administered smt only.case are those who get both smt and plex. smt involved empirical antibiotics as per treating physician,multivitamins,albumin. hepatic encephalopathy (he) will be treated with lactulose and rifaximin. ascites with diuretics if not contraindicated because of renal insufficiency or he. all patients will receive salt restricted, high protein diet (1.5 g/kg of proteins) either enterally/parenterally in addition to thiamine and multivitamins,35 to 45 kcal /kg . cases will be administered smt with plasma exchange session which will be done on alternate day to a maximum of 5 sessions. plex will be discontinued if the patients shows sustained clinical improvement, receive liver transplantation, refuses further plex session,no improvement in clinical condition and intolerant to plex procedure study population: * age - 18-60 years * patients with steroid ineligible(df \> 80\ 30) severe alcoholic hepatitis(bili \> 5 ,inr \> 1.5) study design: randomised controlled study done at department of hepatology,institute of liver and biliary sciences,newdelhi,india.
