My name is Dr. Alison Clifford.
I'm an Assistant Professor of Rheumatology at
the University of Alberta in Edmonton, Canada.
And today we will review "An Approach to the Diagnosis and
Treatment of Giant Cell Arteristis or GCA".
The objectives for today's lecture are number
one to review the epidemiology and current understanding of disease pathogenesis in GCA.
Number two to discuss the common symptoms and signs that should lead one to
consider this diagnosis as well as the appropriate workup to be undertaken.
And number three to review the approach to
treatment and latest data on disease prognosis.
Beginning first with epidemiology,
Giant cell arteristis is a primary systemic large vessel
vasculitis characterized by granulomatous inflammation at the blood vessel walls.
Classically, it targets the temporal arteries,
thoracic aorta and major branch vessels.
However, it bears keeping in mind that any medium to large vessel may be affected.
