Autoimmune liver diseases.

Area of Science:

• Pediatric Gastroenterology and Hepatology
• Immunology
• Autoimmune Disorders

Background:

• Autoimmune liver diseases (AILDs) present with portal tract inflammation, elevated transaminases, IgG, and autoantibodies.
• Pediatric AILDs include autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis (ASC), and de novo AIH post-transplant.
• Disease pathogenesis involves genetic susceptibility triggered by environmental factors or drugs.

Purpose of the Study:

• To provide a comprehensive overview of current knowledge on pediatric autoimmune liver disease.
• To summarize diagnostic criteria, clinical spectrum, and treatment approaches for AILDs in children.

Main Methods:

• Review of existing literature on pediatric autoimmune liver diseases.
• Synthesis of information on diagnosis, pathogenesis, and therapeutic strategies.

Main Results:

• AILDs exhibit a wide clinical spectrum, from asymptomatic cases to fulminant liver failure.
• Diagnosis relies on biochemical, histological findings, and exclusion of other conditions.
• Standard immunosuppressive therapy (corticosteroids, azathioprine) is effective in approximately 80% of pediatric patients.

Conclusions:

• Prompt diagnosis and initiation of immunosuppressive treatment are crucial for managing pediatric AILDs.
• Standard therapy is effective, but alternative treatments are necessary for refractory cases or those with side effects.
• Further research into pathogenesis and novel therapies is warranted.
