Sex-specific differences in primary Sjögren's disease.

Area of Science:

• Immunology
• Rheumatology
• Endocrinology
• Microbiology

Background:

• Autoimmune diseases, such as primary Sjögren's disease (pSD), disproportionately affect females.
• pSD is characterized by exocrine gland dysfunction and systemic manifestations, with distinct clinical phenotypes between sexes.
• The biological underpinnings of this female predilection have remained largely elusive until recent investigations.

Purpose of the Study:

• To review and synthesize current knowledge on factors contributing to the female sex bias in autoimmunity.
• To emphasize mechanisms relevant to the pathogenesis of primary Sjögren's disease.
• To explore potential sex-specific therapeutic strategies for pSD.

Main Methods:

• Review of recent scientific literature focusing on sex differences in autoimmune diseases.
• Analysis of studies investigating the roles of sex hormones, genetic factors, and gut microbiota in pSD.
• Examination of ongoing clinical trials for pSD therapeutics with a focus on sex-specific efficacy.

Main Results:

• Emerging evidence highlights specific regulatory pathways mediating female susceptibility to autoimmunity.
• Sex hormones, genetic predispositions, and gut microbiome alterations are implicated in pSD pathogenesis.
• Distinct clinical presentations in women and men with pSD suggest sex-specific disease mechanisms.

Conclusions:

• Understanding sex-specific factors is crucial for elucidating the pathogenesis of primary Sjögren's disease.
• Targeting sex-specific signaling networks may lead to more efficacious treatments for pSD.
• Further research into hormonal, genetic, and microbial influences can inform personalized therapeutic approaches.
