title: [Giant-cell arteritis with initial resistance to corticosteroids (author's transl)].
abstract: Treatment of giant-cell arteritis rests on corticosteroids. Three observations of Horton arteritis with initial resistance to cortisone are reported. Diagnosis was substantiated by the examination of biopsy specimens. Resistance to therapy was overcome by changing to another corticosteroid. Observations such as those reported here are very uncommon.
