Area of Science:

  • Rheumatology
  • Internal Medicine
  • Vascular Medicine

Context:

  • Giant cell arteritis (GCA), also known as temporal arteritis, is the most prevalent systemic vasculitis.
  • Its incidence appears to be increasing in recent years.
  • GCA primarily affects individuals over 50, involving large and medium-sized arteries, particularly extracranial ones.

Purpose:

  • To review the epidemiology, pathogenesis, diagnostic challenges, complications, and management of Giant Cell Arteritis.
  • To highlight the importance of timely diagnosis and appropriate treatment strategies.

Summary:

  • The aetiopathogenesis of GCA remains unknown, though infectious agents may play a role.
  • A normal temporal artery biopsy does not rule out GCA due to potential skip lesions.

  • Key complications include permanent visual loss, ischemic strokes, and aortic aneurysms.

    • Impact:

    • Current treatment relies on high-dose corticosteroids, lacking alternatives with fewer adverse effects.
    • Effective diagnosis and management appear to prevent increased mortality in treated GCA patients.
    • Understanding GCA is vital for preventing severe, potentially irreversible complications in the aging population.
