The efficacy and adverse effects of budesonide in remission induction treatment of autoimmune hepatitis: a retrospective study

British Society of Gastroenterology guidelines for diagnosis and management of autoimmune hepatitis

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease which, if untreated, often leads to cirrhosis, liver failure and death. The last British Society of Gastroenterology (BSG) guideline for the management of AIH was published in 2011. Since then, our understanding of AIH has advanced in many areas. This update to the previous guideline was commissioned by the BSG and developed by a multidisciplinary group. The aim of this guideline is to review and summarise the current evidence, in order to inform and guide diagnosis and management of patients with AIH and its variant syndromes. The main focus is on AIH in adults, but the guidelines should also be relevant to older children and adolescents.

What is the optimal first-line treatment of autoimmune hepatitis? A systematic review with meta-analysis of randomised trials and comparative cohort studies

OBJECTIVES

Uncertainty remains about many aspects of first-line treatment of autoimmune hepatitis (AIH).

DESIGN

Systemic review with meta-analysis (MA).

DATA SOURCES

Bespoke AIH Endnote Library, updated to 30 June 2024.

ELIGIBILITY CRITERIA

Randomised controlled trials (RCTs) and comparative cohort studies including adult patients with AIH, reporting death/transplantation, biochemical response (BR) and/or adverse effects (AEs).

DATA EXTRACTION AND SYNTHESIS

Data pooled in MA as relative risk (RR) under random effects. Risk of bias (ROB) assessed using Cochrane ROB-2 and ROBINS-1 tools.

RESULTS

From seven RCTs (five with low and two with some ROB) and 18 cohort studies (12 moderate ROB, six high for death/transplant), we found lower death/transplantation rates in (a) patients receiving pred+/-aza (vs no pred): overall (RR 0.38 (95% CI 0.20 to 0.74)), in patients without symptoms (0.38 (0.19-0.75)), without cirrhosis (0.30 (0.14-0.65)), and with decompensated cirrhosis (RR 0.38 (0.23-0.61)), and (b) patients receiving pred+aza (vs pred alone) (0.38 (0.22-0.65)). Patients receiving higher (vs lower) initial pred doses had similar BR rates (RR 1.07 (0.92-1.24)) and mortality (0.71 (0.25-2.05)) but more AEs (1.73 (1.17-2.55)). Patients receiving bud (vs pred) had similar BR rates (RR 0.99 (0.71-1.39)), with fewer cosmetic AEs (0.46 (0.34-0.62)). Patients receiving mycophenolate mofetil (MMF) (vs aza) had similar BR rates (RR 1.32 (0.73-2.38)) and fewer AEs requiring drug cessation (0.20 (0.09-0.43)).

CONCLUSIONS

Mortality is lower in pred-treated (vs untreated) patients, overall and in several subgroups, and in those receiving pred+aza (vs pred). Higher initial pred doses confer no clear benefit and cause more AEs. Bud (vs pred) achieves similar BR rates, with fewer cosmetic AEs. MMF (vs aza) achieves similar BR rates, with fewer serious AEs.

Budesonide in Liver Immunology: A Therapeutic Opportunity in Liver Transplantation

Purpose of Review

A major remaining challenge in liver transplantation is achieving the balance between adequate immunosuppression to prevent allograft rejection and minimising immunosuppression-related side effects. Systemic corticosteroids contribute to the development of multi-system adverse effects that increase recipient morbidity and mortality. Oral budesonide undergoes significant first-pass hepatic metabolism, thereby minimising systemic availability, but maintains a similar immunosuppressive impact on the liver and gastrointestinal tract as systemic corticosteroids. This review aims to explore the rationale for oral budesonide as an alternative immunosuppressant to conventional corticosteroids following liver transplantation.

Recent findings

Despite increasing evidence of efficacy and safety in other gastrointestinal conditions, research on the role of budesonide as an alternative immunosuppressant to conventional corticosteroids in the liver transplant setting remains scarce. However, existing literature suggests efficacy in the treatment and prevention of acute rejection after liver transplantation, with minimal toxicity.

Summary

The unique pharmacokinetic profile of oral budesonide may address the unmet need for a medical therapy that has efficacy but with a better safety profile compared to conventional corticosteroids in the liver transplant setting.

Budesonide as first-line treatment in patients with autoimmune hepatitis seems inferior to standard predniso(lo)ne administration

BACKGROUND AND AIMS

In patients with non-severe acute or chronic autoimmune hepatitis (AIH) without cirrhosis, clinical practice guidelines recommend indistinct use of prednisone or budesonide. However, budesonide is infrequently used in clinical practice. We aimed to describe its use and compare its efficacy and safety with prednisone as first-line options.

APPROACH AND RESULTS

This was a retrospective, multicenter study of 105 naive AIH patients treated with budesonide as the first-line drug. The control group included 276 patients treated with prednisone. Efficacy was assessed using logistic regression and validated using inverse probability of treatment weighting propensity score. The median time to biochemical response (BR) was 3.1 months in patients treated with budesonide and 4.9 months in those with prednisone. The BR rate was significantly higher in patients treated with prednisone (87% vs. 49% of patients with budesonide, p < 0.001). The probability of achieving BR, assessed using the inverse probability of treatment weighting propensity score, was significantly lower in the budesonide group (OR = 0.20; 95% CI: 0.11-0.38) at any time during follow-up, and at 6 (OR = 0.51; 95% CI: 0.29-0.89) and 12 months after starting treatment (0.41; 95% CI: 0.23-0.73). In patients with transaminases <2 × upper limit of normal, BR was similar in both treatment groups. Prednisone treatment was significantly associated with a higher risk of adverse events (24.2% vs. 15.9%, p = 0.047).

CONCLUSIONS

In the real-life setting, the use of budesonide as first-line treatment is low, and it is generally prescribed to patients with perceived less disease activity. Budesonide was inferior to prednisone as a first-line drug but was associated with fewer side effects.

Budesonide in the first line treatment of patients with autoimmune hepatitis

Budesonide is a glucocorticoid characterized by its local action, with a low systemic bioavailability. Since the original trial comparing budesonide with prednisone in 2010, it is recommended as an effective alternative for the treatment of non-severe acute or chronic autoimmune hepatitis. In this document, we review the general pharmacologic properties of glucocorticoids, the available evidence for the use of budesonide as first line option for autoimmune hepatitis as well as the safety profile of the drug.
