Prednisolone or Pentoxifylline for Alcoholic Hepatitis

BACKGROUND Alcoholic hepatitis is a clinical syndrome characterized by jaundice and liver impairment that occurs in patients with a history of heavy and prolonged alcohol use. The short-term mortality among patients with severe disease exceeds 30%. Prednisolone and pentoxifylline are both recommended for the treatment of severe alcoholic hepatitis, but uncertainty about their benefit persists. METHODS We conducted a multicenter, double-blind, randomized trial with a 2-by-2 factorial design to evaluate the effect of treatment with prednisolone or pentoxifylline. The primary end point was mortality at 28 days. Secondary end points included death or liver transplantation at 90 days and at 1 year. Patients with a clinical diagnosis of alcoholic hepatitis and severe disease were randomly assigned to one of four groups: a group that received a pentoxifylline-matched placebo and a prednisolone-matched placebo, a group that received prednisolone and a pentoxifylline-matched placebo, a group that received pentoxifylline and a prednisolone-matched placebo, or a group that received both prednisolone and pentoxifylline. RESULTS A total of 1103 patients underwent randomization, and data from 1053 were available for the primary end-point analysis. Mortality at 28 days was 17% (45 of 269 patients) in the placebo-placebo group, 14% (38 of 266 patients) in the prednisolone-placebo group, 19% (50 of 258 patients) in the pentoxifylline-placebo group, and 13% (35 of 260 patients) in the prednisolone-pentoxifylline group. The odds ratio for 28-day mortality with pentoxifylline was 1.07 (95% confidence interval [CI], 0.77 to 1.49; P=0.69), and that with prednisolone was 0.72 (95% CI, 0.52 to 1.01; P=0.06). At 90 days and at 1 year, there were no significant between-group differences. Serious infections occurred in 13% of the patients treated with prednisolone versus 7% of those who did not receive prednisolone (P=0.002). CONCLUSIONS Pentoxifylline did not improve survival in patients with alcoholic hepatitis. Prednisolone was associated with a reduction in 28-day mortality that did not reach significance and with no improvement in outcomes at 90 days or 1 year.

Steroids or pentoxifylline for alcoholic hepatitis (STOPAH): study protocol for a randomised controlled trial

AbstractBackgroundAlcoholic hepatitis is the most florid presentation of alcohol-related liver disease. In its severe form, defined by a Maddrey’s discriminant function (DF) ≥32, the 28-day mortality rate is approximately 35%. A number of potential treatments have been subjected to clinical trials, of which two, corticosteroids and pentoxifylline, may have therapeutic benefit. The role of corticosteroids is controversial as trial results have been inconsistent, whereas the role of pentoxifylline requires confirmation as only one previous placebo-controlled trial has been published.Methods/designSTOPAH is a multicentre, double-blind, factorial (2 × 2) trial in which patients are randomised to one of four groups: 1.Group A: placebo / placebo2.Group B: placebo / prednisolone3.Group C: pentoxifylline / placebo4.Group D: pentoxifylline / prednisolone The trial aims to randomise 1,200 patients with severe alcoholic hepatitis, in order to provide sufficient power to determine whether either of the two interventions is effective. The primary endpoint of the study is mortality at 28 days, with secondary endpoints being mortality at 90 days and 1 year.DiscussionSTOPAH aims to be a definitive study to resolve controversy around the existing treatments for alcoholic hepatitis. Eligibility criteria are based on clinical parameters rather than liver biopsy, which are aligned with standard clinical practice in most hospitals. The use of a factorial design will allow two treatments to be evaluated in parallel, with efficient use of patient numbers to achieve high statistical power.Trial registrationEudraCT reference number: 2009-013897-42ISRCTN reference number: ISRCTN88782125

Site and stage of colorectal cancer influence the likelihood and distribution of disease recurrence and postrecurrence survival: data from the FACS randomized controlled trial

Objectives:To describe patterns of recurrence and postrecurrence survival in a large cohort of accurately staged patients with Dukes’ A-C colorectal cancer. Background:Recurrence remains a frequent cause of mortality after the treatment of colorectal cancer with curative intent. Understanding the likelihood and site of recurrence informs adjuvant treatment and follow-up. Methods:Retrospective cohort analysis of data from the FACS (follow-up after colorectal cancer surgery) trial after a median 4.4 years of follow-up; postrecurrence survival was calculated using the Kaplan-Meier method. Results:Complete data were available for 94% of patients; 189 (17%) patients had experienced recurrence. Incidence of recurrence varied according to the site of the primary (right colon: 51/379, 14%; left colon: 68/421, 16%; rectum: 70/332, 21%; P = 0.023) and initial stage (Dukes’ A: 26/249, 10%; Dukes’ B: 81/537, 15%; Dukes’ C: 82/346, 24%; P < 0.0001). Pulmonary recurrence was most frequently associated with rectal tumors, and multisite/other recurrence with right-sided colonic tumors. Recurrences from lower-stage tumors were more likely to be treatable with curative intent (Dukes’ A: 13/26, 50%; Dukes’ B: 32/81, 40%; Dukes’ C: 20/82, 24%; P = 0.03). Those with rectal tumors benefited most from follow-up (proportion with treatable recurrence: rectum 30/332, 9%; left colon 23/421, 6%; right colon 12/379, 3%; P = 0.003). Both initial stage (log rank P = 0.005) and site of primary (log rank P = 0.01) influenced postrecurrence survival. Conclusions:The likelihood and site of recurrence, and survival, are influenced by the site and stage of the primary tumor. Those with rectal cancers benefited most from follow-up.ISRCTN 41458548

The clinical effectiveness and cost-effectiveness of STeroids Or Pentoxifylline for Alcoholic Hepatitis (STOPAH): a 2 × 2 factorial randomised controlled trial.

BACKGROUND Alcoholic hepatitis (AH) is a distinct presentation of alcoholic liver disease arising in patients who have been drinking to excess for prolonged periods, which is characterised by jaundice and liver failure. Severe disease is associated with high short-term mortality. Prednisolone and pentoxifylline (PTX) are recommended in guidelines for treatment of severe AH, but trials supporting their use have given heterogeneous results and controversy persists about their benefit. OBJECTIVES The aim of the clinical effectiveness and cost-effectiveness of STeroids Or Pentoxifylline for Alcoholic Hepatitis trial was to resolve the clinical dilemma on the use of prednisolone or PTX. DESIGN The trial was a randomised, double-blind, 2 × 2 factorial, multicentre design. SETTING Sixty-five gastroenterology and hepatology inpatient units across the UK. PARTICIPANTS Patients with a clinical diagnosis of AH who had a Maddreys discriminant function value of ≥ 32 were randomised into four arms: A, placebo/placebo; B, placebo/prednisolone; C, PTX/placebo; and D, PTX/prednisolone. Of the 5234 patients screened for the trial, 1103 were randomised and after withdrawals, 1053 were available for primary end-point analysis. INTERVENTIONS Those allocated to prednisolone were given 40 mg daily for 28 days and those allocated to PTX were given 400 mg three times per day for 28 days. OUTCOMES The primary outcome measure was mortality at 28 days. Secondary outcome measures included mortality or liver transplant at 90 days and at 1 year. Rates of recidivism among survivors and the impact of recidivism on mortality were assessed. RESULTS At 28 days, in arm A, 45 of 269 (16.7%) patients died; in arm B, 38 of 266 (14.3%) died; in arm C, 50 of 258 (19.4%) died; and in arm D, 35 of 260 (13.5%) died. For PTX, the odds ratio for 28-day mortality was 1.07 [95% confidence interval (CI) 0.77 to 1.40; p = 0.686)] and for prednisolone the odds ratio was 0.72 (95% CI 0.52 to 1.01; p = 0.056). In the logistic regression analysis, accounting for indices of disease severity and prognosis, the odds ratio for 28-day mortality in the prednisolone-treated group was 0.61 (95% CI 0.41 to 0.91; p = 0.015). At 90 days and 1 year there were no significant differences in mortality rates between the treatment groups. Serious infections occurred in 13% of patients treated with prednisolone compared with 7% of controls (p = 0.002). At the 90-day follow-up, 45% of patients reported being completely abstinent, 9% reported drinking within safety limits and 33% had an unknown level of alcohol consumption. At 1 year, 37% of patients reported being completely abstinent, 10% reported drinking within safety limits and 39% had an unknown level of alcohol consumption. Only 22% of patients had attended alcohol rehabilitation treatment at 90 days and 1 year. CONCLUSIONS We conclude that prednisolone reduces the risk of mortality at 28 days, but this benefit is not sustained beyond 28 days. PTX had no impact on survival. Future research should focus on interventions to promote abstinence and on treatments that suppress the hepatic inflammation without increasing susceptibility to infection.
