Iron deficiency is the main cause of anemia in both sexes, with women being more commonly affected. Iron therapy is currently considered an effective and safe remedy to replenish the iron storages. Iron can be administrated both orally and intravenously. In particular, intravenous (IV) iron therapy is widely used when oral iron preparations are either not tolerated or ineffective. Indeed, IV iron improves iron stores more rapidly. Two main immunological responses have been described for iron hypersensitivity reactions (HSRs): IgE-mediated allergy and complement activation-related pseudo-allergy. Here, we report 3 cases of adult patients with iron allergy, who were successfully treated with two different desensitization procedures, respectively. Analysis of these cases demonstrates that, in the presence of HSRs to iron products, desensitization is an effective and safe procedure that prevents treatment discontinuation and hence allows therapeutic target achievement.

Abstract

Iron deficiency is the main cause of anemia in both sexes, with women being more commonly affected. Iron therapy is currently considered an effective and safe remedy to replenish the iron storages. Iron can be administrated both orally and intravenously. In particular, intravenous (IV) iron therapy is widely used when oral iron preparations are either not tolerated or ineffective. Indeed, IV iron improves iron stores more rapidly. Two main immunological responses have been described for iron hypersensitivity reactions (HSRs): IgE-mediated allergy and complement activation-related pseudo-allergy. Here, we report 3 cases of adult patients with iron allergy, who were successfully treated with two different desensitization procedures, respectively. Analysis of these cases demonstrates that, in the presence of HSRs to iron products, desensitization is an effective and safe procedure that prevents treatment discontinuation and hence allows therapeutic target achievement.
