Autoimmune hepatitis: Challenges and novelties.

Area of Science:

• Hepatology
• Immunology
• Internal Medicine

Background:

• Autoimmune hepatitis (AIH) is a chronic inflammatory liver condition with unknown causes.
• It predominantly affects women and is marked by elevated liver enzymes, immunoglobulins, autoantibodies, and specific biopsy findings.
• Standard treatment combines corticosteroids and azathioprine.

Purpose of the Study:

• To review key diagnostic and treatment strategies for autoimmune hepatitis.
• To highlight challenges encountered in the clinical management of AIH.
• To provide an overview of current therapeutic approaches and their limitations.

Main Methods:

• Literature review of diagnostic criteria for autoimmune hepatitis.
• Analysis of treatment guidelines and outcomes for AIH.
• Discussion of second- and third-line therapy options for non-responsive or intolerant patients.

Main Results:

• AIH diagnosis relies on clinical, serological, and histological evidence.
• Corticosteroids and azathioprine are first-line treatments, effective in 60-80% of cases.
• A significant proportion of patients (20-40%) require alternative therapies due to side effects or lack of efficacy.

Conclusions:

• Accurate diagnosis of autoimmune hepatitis is crucial for effective management.
• Personalized treatment strategies are necessary, considering patient response and tolerance.
• Addressing challenges in AIH treatment, including refractory cases, remains an important clinical focus.
