PG - 589-94 AB - Corticosteroids are therapeutic drugs widely used in cases of allergic, inflammatory and autoimmune diseases, but sometimes allergic hypersensitivity reactions have been reported as a rare adverse effect of the corticosteroids themselves. Moreover, glucocorticoids can induce gastric lesions; thatÂ’s why they are sometimes administered intravenously together with some drugs such as proton pump inhibitors (PPI) or inhibitors of histamine-2 receptors (antiH2) working as gastric protectors. Although it is difficult to establish which drug was responsible in case of hypersensitivity reactions, as hypersensitivity reactions following to the use of PPI or anti-H2 have been already described in literature. Here we describe two cases of immediate-type hypersensitivity triggered from the administration of a corticosteroid plus a gastroprotective agent and the diagnostic check up required in both these patients.
