Corticosteroid Usage in Giant Cell Arteritis

ABSTRACT

Giant cell arteritis (GCA) is a condition that can cause irreversible visual loss if untreated. While corticosteroids remain the mainstay of treatment to prevent visual loss, the type, dose, route, and duration of corticosteroid treatment of GCA remain controversial. Our study surveyed neuro-ophthalmologists to determine commonly prescribed dosages of corticosteroids for the treatment of GCA with or without visual loss. For patients with acute visual loss, 52% would use intravenous (IV), 46% would use IV or oral and 2% would use oral corticosteroids. Seventy-three per cent would use 500 to 1000 mg IV methylprednisolone in this group. For patients with GCA without acute visual loss, 67% would use the oral route, 30% would use IV or oral, and 3% indicated they would use IV route of treatment. Seventy-five per cent would use 1.0 to 1.5 mg/kg oral prednisone in this group. Our results suggest a majority but not a complete consensus for route and dose of corticosteroid treatment in GCA and confirm conventional recommendations for high dose IV corticosteroids for GCA with visual loss and lower dose oral regimens for GCA without visual loss.
