Management of hypersensitivity reactions to iodinated contrast media.
All iodinated contrast media (CM) are known to cause both immediate ( £ 1 h) and nonimmediate (>1 h) hypersensitivity reactions. Although for most immediate reactions an allergic hypersensitivity cannot be demonstrated, recent studies indicate that the severe immediate reactions may be IgE-mediated, while most of the nonimmediate exanthematous skin reactions, appear to be T-cell mediated. Patie...
متن کاملAllergic Immediate Hypersensitivity to Iodinated Contrast Media
Background: Immediate hypersensitivity reactions (IHR) to iodinated contrast media (ICM) have traditionally been considered nonallergic; however, the increasingly frequent reporting of positive skin test and basophil activation test results suggests a specifi c allergic mechanism in some patients. Skin tests have been proposed as a useful tool for diagnosis, although their sensitivity and predi...
متن کاملIodinated contrast media and their adverse reactions.
Cross-use of technology between nuclear medicine and radiology technologists is expanding. The growth of PET/CT and the increasing use of intravenous contrast agents during these procedures bring the nuclear medicine technologist into direct contact with these agents and their associated complications. A basic understanding of the occurrence, risk factors, clinical features, and management of t...
متن کاملSkin testing in patients with hypersensitivity reactions to iodinated contrast media - a European multicenter study.
BACKGROUND Iodinated contrast media cause both immediate and nonimmediate hypersensitivity reactions. The aim of this prospective study was to determine the specificity and sensitivity of skin tests in patients who have experienced such reactions. METHODS Skin prick, intradermal and patch tests with a series of contrast media were conducted in 220 patients with either immediate or nonimmediat...
متن کاملSevere hypersensitivity reactions to iodinated contrast media: clinical and immunological features in a cohort of patients
Background Iodinated contrast media (ICM) are diagnostic agents used in millions of X-ray procedures yearly. Although current agents are usually well tolerated, mild immediate hypersensitivity reactions (IHR) occur in about 0.15% to 3% of administrations and severe IHRs in 0.01% to 0.04%. Despite this low incidence these reactions are an important clinical problem because the increasingly large...
