Evidence-based Role of Aspirin in Giant Cell Arteritis: A Literature Review

Area of Science:

• Rheumatology
• Vascular Medicine
• Internal Medicine

Background:

• Giant cell arteritis (GCA), also known as temporal arteritis, is a prevalent form of vasculitis affecting medium to large arteries, primarily in older adults.
• GCA can manifest with diverse symptoms, ranging from unexplained fever to severe cranial ischemic events like irreversible vision loss.
• Prompt corticosteroid therapy is crucial for mitigating GCA-associated complications.

Purpose of the Study:

• To review the evidence supporting the use of aspirin as an adjunctive therapy to corticosteroids in managing GCA.
• To evaluate aspirin's dual role in GCA treatment, encompassing its antithrombotic and anti-inflammatory effects.
• To assess aspirin's efficacy in preventing cranial ischemic complications in patients with GCA.

Main Methods:

• Systematic review of existing literature on aspirin's use in GCA.
• Analysis of studies investigating aspirin's antithrombotic and anti-inflammatory mechanisms.
• Evaluation of clinical trial data and observational studies on aspirin's impact on GCA outcomes.

Main Results:

• Aspirin demonstrates both antithrombotic and anti-inflammatory properties relevant to GCA management.
• Evidence suggests aspirin may reduce the risk of cranial ischemic complications when used alongside steroids.
• Further research is warranted to fully elucidate aspirin's optimal role and dosage in GCA treatment.

Conclusions:

• Aspirin may serve as a valuable adjunct to standard corticosteroid therapy for GCA.
• The combined use of aspirin and steroids holds promise for preventing serious ischemic events in GCA patients.
• Continued investigation into aspirin's therapeutic benefits in GCA is recommended.
