[Common aspects between psoriatic spondylitis and ankylosing spondylitis]

Area of Science:

• Rheumatology
• Immunology
• Spondyloarthritis

Context:

• Ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are chronic inflammatory diseases.
• Both conditions primarily affect the axial skeleton and peripheral joints.
• Understanding their shared characteristics is crucial for accurate diagnosis and treatment.

Purpose:

• To review and analyze the commonalities between ankylosing spondylitis and psoriatic arthritis.
• To explore shared aspects across conceptual, clinical, and therapeutic domains.
• To establish a unified understanding of these conditions within a broader disease category.

Summary:

• This review examines shared features of AS and PsA at conceptual, diagnostic, clinical, and therapeutic levels.
• Key commonalities identified include disease mechanisms, clinical manifestations, and treatment strategies.
• The analysis supports integrating AS and PsA under the concept of axial spondyloarthritis.

Impact:

• Highlights the interconnectedness of AS and PsA, potentially simplifying diagnostic pathways.
• Suggests a unified therapeutic approach for axial spondyloarthritis, improving patient management.
• Provides a framework for future research into shared underlying pathologies and targeted therapies.
