Are Gender Differences Important for Autoimmune Liver Diseases?

Area of Science:

• Autoimmune Liver Diseases
• Gender Medicine
• Hepatology

Background:

• Autoimmune liver diseases (AILDs) encompass conditions like autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC).
• Limited understanding exists regarding the influence of sex on the pathogenesis and progression of these liver conditions.
• Gender medicine has seen significant growth, highlighting the need to explore sex-based variations in disease.

Purpose of the Study:

• To review and update knowledge on gender disparities in autoimmune liver diseases.
• To analyze data published between 1999 and 2023 concerning sex differences in AILDs.
• To emphasize the need for further research into sex-specific aspects of AILDs.

Main Methods:

• Systematic review of published literature from 1999 to 2023.
• Analysis of epidemiological data on autoimmune liver diseases.
• Evaluation of clinical data on disease natural history and complications.

Main Results:

• Clinical data indicate significant sex differences in the natural history of autoimmune liver diseases.
• Gender disparities are evident in the onset of end-stage liver disease complications, including cancer incidence.
• Disease onset may occur earlier than previously recognized, potentially in pediatric populations.

Conclusions:

• Sex plays a crucial role in the natural history and outcomes of autoimmune liver diseases.
• Further basic science and clinical research are urgently needed to elucidate the impact of sex on AILD pathogenesis.
• Understanding gender disparities is essential for advancing the diagnosis and treatment of autoimmune liver diseases.
