ABSTRACT
C1 esterase inhibitor (C1-INH) deficiency is a rare disorder that lacks consensus for diagnosis therapy and management. Recognizing that Canada is behind the European approach to this disorder, we have formed the Canadian Hereditary Angioedema Society (CHAES)/Société d'angioédème héréditaire du Canada (SAHC) to foster knowledge of this disorder in Canada and to advance care of patients with this disorder in Canada. We here present a review of treatment of this disorder in Canada including prevention of angioedema events and use of replacement therapy and present an algorithm for diagnosis therapy and management of C1-INH deficiency in Canada for discussion at our International Conference on Hereditary Angioedema to be held in Toronto, Canada, October 24th to 26th, 2003.
