Early change in bilirubin levels is an important prognostic factor in severe alcoholic hepatitis treated with prednisolone

Liver transplantation for alcoholic liver disease

Alcoholic liver disease (ALD) is the second commonest indication for liver transplantation after viral hepatitis in the United States and Europe. Controversies surround the indications and allocation of scarce and expensive resource for this so called self inflicted disease. Controversies stem from the apprehension that alcoholic recipients are likely to relapse and cause damage to the graft. There is a need to select those candidates with lower risk for relapse with the available predictive factors and scores. Substance abuse specialist and psychiatrists are mandatory in the pre-transplant evaluation and in the post-transplant follow-up. There is conflicting evidence to support a fixed period of pretransplant abstinence, although most units do follow this. Alcoholic hepatitis (AH) continues to be a contraindication for transplantation, however there is a need for further research in this field as a subset of patients with AH who do not respond to medical treatment, have high early mortality and could benefit from transplantation. One year, 3-year, and 5-year survival post-transplant is similar for both ALD and non-ALD recipients. The incidence of post-transplant rejection and retransplantation is also similar to other recipients. ALD with viral hepatitis especially hepatitis C virus leads to a more aggressive liver disease with early presentation for transplantation. ALD patients are more prone to develop de-novo malignancy; this is attributed to the long term effect of alcohol, tobacco combined with immunosuppression. Post-transplant surveillance is important to detect early relapse to alcoholism, presence of de-novo malignancy and treat the same adequately.

Granulocytapheresis in the treatment of severe alcoholic hepatitis: a case series

OBJECTIVES

The management of alcoholic hepatitis remains controversial. Anti-tumour necrosis factor treatments have been studied recently. We piloted the use of granulocytapheresis (GCAP) in the management of severe alcoholic hepatitis.

METHODS

GCAP was performed on six patients with severe alcoholic hepatitis. Their clinical and laboratory progress was reviewed retrospectively.

RESULTS

Six of the patients underwent at least one session of GCAP. Three of the patients had coexistent renal failure and five of the six patients were corticosteroid nonresponders. All patients tolerated the procedure. However, three of the patients died during their hospital admission within 4 days of GCAP treatment. These three patients suffered from torrential variceal haemorrhage, multiorgan failure and pneumonia, respectively. Two patients died 18 and 25 days after their GCAP treatment, both with multiorgan failure. The survivor was the sole corticosteroid responder of the group. There was a trend towards a fall in serum bilirubin level after GCAP, but this did not reach significance.

CONCLUSION

GCAP is tolerated in severe alcoholic hepatitis; however, we have no evidence of survival advantage with this treatment.

The management of alcoholic hepatitis

Alcoholic hepatitis is an increasingly common reason for hospital admission which carries a high mortality. This review describes a clinical approach to the definition, assessment and management of this condition.

Pharmacokinetic-pharmacodynamic modeling of manganese after a single intravenous infusion of mangafodipir in patients with acute alcoholic hepatitis

To determine the pharmacokinetic (PK) profile of manganese (Mn) after a 2-hour intravenous infusion of mangafodipir at 5 micromol/kg body weight and to correlate Mn concentrations with oxidative stress, early decrease in serum total bilirubin concentration, and prothrombin time (PT) in chronic alcoholic patients with acute alcoholic hepatitis. In 7 patients, a total of 49 serum Mn concentrations were determined on day 1 (before the start of the infusion and 15, 30, and 45 minutes after the end of the infusion) and on days 2, 7, 14, and 21. Fifty-seven PTs, reflecting liver activity, were measured on days 1, 2, 7, 14, and 21 and at months 1, 2, and 3. A population PK-pharmacodynamic model was developed to describe the kinetics of serum Mn concentrations and PT, to estimate interpatient variability, and to test covariate influence. A 2-compartment model with zero-order absorption and first-order elimination best described the data, and a signal transduction model with 2 transit compartments best described PT. Mean PK estimates and the corresponding interindividual variabilities (%) were clearance 23.1 L/h (34%), central and peripheral volume of distribution 35.4 and 1090 L, respectively, intercompartmental clearance 27.3 L (34%), endogenous Mn concentrations 15.8 nmol/L, slope-relating effect to concentration 141 nmol x L(-1) x s(-1) (52%), and mean transit time (tau) 3.8 days (34%). When patients had an early decrease in bilirubin at day 7, tau increased to 28.2 days. Serum Mn concentrations could be related to a decrease in PT; the effect was longer in patients with an early decrease in total bilirubin serum concentrations.

Alcoholic liver disease

These recommendations provide a data-supported approach. They are based on the following: (i) a formal review and analysis of the recently published world literature on the topic (Medline search); (ii) American College of Physicians Manual for Assessing Health Practices and Designing Practice Guidelines (1); (iii) guideline policies, including the American Association for the Study of Liver Diseases (AASLD) Policy on the development and use of practice guidelines and the AGA Policy Statement on Guidelines (2); and (iv) the experience of the authors in the specified topic. Intended for use by physicians, these recommendations suggest preferred approaches to the diagnostic, therapeutic, and preventive aspects of care. They are intended to be flexible, in contrast to the standards of care, which are inflexible policies to be followed in every case. Specific recommendations are based on relevant published information. To more fully characterize the quality of evidence supporting the recommendations, the Practice Guideline Committee of the AASLD requires a Class (reflecting the benefit vs. risk) and Level (assessing the strength or certainty) of Evidence to be assigned and reported with each recommendation (Table 1, adapted from the American College of Cardiology and the American Heart Association Practice Guidelines) (3,4).

Current concepts and controversies in the treatment of alcoholic hepatitis

The treatment of alcoholic hepatitis remains one of the most debated topics in medicine and a field of continued research. In this review, we discuss the evolution of scoring systems, including the recent development of the Glasgow alcoholic hepatitis score, role of liver biopsy and current treatment interventions. Studies of treatment interventions with glucocorticoids, pentoxifylline, infliximab, s-adenosyl-methionine, and colchicine are reviewed with discussion on quality. Glucocorticoids currently remain the mainstay of treatment for severe alcoholic hepatitis.

The management of severe alcoholic liver disease and variceal bleeding in the intensive care unit

PURPOSE OF REVIEW

To address recent advances in the understanding and management of alcohol-related chronic liver disease and its acute complications.

RECENT FINDINGS

Refinements have been made in the prognosis and treatment of alcoholic hepatitis, and new insights have been gained into the pathophysiology of the hepatorenal syndrome. Further trial evidence has emerged concerning therapy in the hepatorenal syndrome, and there has been some clarification of the benefits and risks relating to albumin dialysis/extracorporeal liver support, and consensus in the early management of variceal haemorrhage.

SUMMARY

Recent developments have led to modifications in the standard of care of patients with severe alcoholic liver disease, many of which are highly applicable to the general critical care setting. These changes apply specifically to alcoholic hepatitis, the hepatorenal syndrome and variceal bleeding, common conditions with a high mortality rate, upon which changes in practice can have a significant impact.

Acute alcoholic hepatitis

Acute alcoholic hepatitis (AAH) is a frequent inflammatory liver disease with high short-term mortality rate. In this review, relationships between alcohol abuse and the epidemiology and the outcomes of AAH are discussed, as well as AAH pathogenesis. The role of endotoxins, tumor necrosis factor alpha, fibroblasts, and immune response to altered hepatocyte proteins is discussed. The need of a careful prognosis, supported by the use of Maddrey score, by the model for end-stage liver disease [Mayo end-stage liver disease (MELD)] score or by the Glasgow alcoholic hepatitis score, is outlined, as the use of the most effective drugs (glucocorticoids and anti-tumor necrosis factor alpha infliximab) is recommended only in severe AAH cases. The problems of liver transplant in severe AAH, and the need of a 6-month alcohol abstinence before transplant, are discussed, as well as the need of a careful psychologic assessment before the transplant.

Alcoholic Hepatitis

Alcoholic hepatitis (AH) is a common disease associated with significant morbidity and mortality. Most often the diagnosis is suggested by a history of heavy alcohol excess in a patient with features of hepatic decompensation. In its purest form, AH is a histologic diagnosis of acute hepatic inflammation in response to alcohol. The primary objective of treatment for AH is to support long-term alcohol abstinence and to achieve adequate nutrition with lifestyle modification; goal setting and education are integral to long-term medical management. Severity at presentation (calculated by way of the Maddrey score) determines outcome. Patients with AH represent a heterogeneous group with regard to severity and pathogenesis, with various therapeutic interventions assessed in patients with severe AH. To date, corticosteroids have been studied most, and despite remaining controversial, warrant a place in the treatment of selected patients. Recent advances in unraveling the aspects of disease pathogenesis in AH have raised the possibility of targeted therapies, such as anti-tumor necrosis factor-a monoclonals and pentoxifylline. Orthotopic liver transplantation is not recommended for patients with severe acute AH, as most have an unclear long-term prognosis in the context of ongoing excess alcohol ingestion at presentation.
