Diagnostic Challenges and Modern Therapeutic Strategies in Giant Cell Arteritis

Area of Science:

• Rheumatology
• Internal Medicine
• Vascular Medicine

Background:

• Giant cell arteritis (GCA) is a systemic vasculitis posing significant diagnostic challenges.
• Its heterogeneous presentation and lack of specific signs complicate early and accurate diagnosis.
• Potential severe complications, particularly irreversible vision loss, underscore the need for improved diagnostic strategies.

Purpose of the Study:

• To comprehensively review the diagnostic challenges associated with GCA.
• To synthesize current evidence on advances in GCA diagnosis and management.
• To highlight recent developments in classification criteria, imaging, biomarkers, and therapeutics.

Main Methods:

• Systematic review of current literature on Giant Cell Arteritis diagnosis.
• Analysis of recent advancements in classification criteria (e.g., ACR/EULAR).
• Evaluation of emerging diagnostic tools including advanced imaging and novel biomarkers.

Main Results:

• Diagnostic challenges in GCA stem from clinical heterogeneity and non-specific symptoms.
• Recent advances include updated classification criteria and improved imaging techniques (e.g., ultrasound, MRI).
• Biomarker research shows promise, though none are currently pathognomonic for GCA.

Conclusions:

• Accurate and timely diagnosis of GCA remains a critical clinical challenge.
• Integration of new classification criteria, advanced imaging, and potential biomarkers is essential.
• Ongoing research into novel therapeutic strategies is crucial for managing GCA and preventing complications like vision loss.
