Area of Science:

  • Rheumatology
  • Vasculitis
  • Immunology

Context:

  • Giant cell arteritis (GCA) is a vasculitic syndrome impacting medium and large arteries.
  • Temporal artery involvement is the most common presentation.
  • Characterized by granulomatous inflammation with T cells, macrophages, and giant cells.

Purpose:

  • To review the clinical implications of giant cell arteritis.
  • To emphasize the importance of early recognition and prompt treatment.
  • To discuss diagnostic criteria and treatment strategies.

Summary:

  • Diagnosis relies on five American College of Rheumatology criteria (age ≥50, new headache, temporal artery tenderness/decreased pulse, elevated ESR, abnormal biopsy).
  • GCA is a significant cause of morbidity and mortality in the elderly.

  • Corticosteroid therapy is the mainstay, with initial doses of 40-65 mg/day, followed by maintenance of 5-7.5 mg/day prednisolone for approximately 5 years.

    • Impact:

    • Early diagnosis and treatment improve prognosis.
    • Highlights the importance of recognizing GCA in the elderly population.
    • Informs clinical practice regarding diagnosis and management of GCA.
