Allergic 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 کاملImmediate hypersensitivity reactions to IV non-ionic iodinated contrast in computed tomography
BACKGROUND With use of computed tomography (CT), intravenous contrast media is used routinely to help define anatomy and identify any pathology. Non-ionic iodinated contrast agents have largely replaced ionic agents and although rare, reactions to contrast are still important and more so with the continual increase in CT examinations in the last decade. OBJECTIVE To examine the incidence, sev...
متن کاملManagement 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 کاملThe Incidence, Classification, and Management of Acute Adverse Reactions to the Low-Osmolar Iodinated Contrast Media Isovue and Ultravist in Contrast-Enhanced Computed Tomography Scanning
Some epidemiologic surveillance studies have recorded adverse drug reactions to radiocontrast agents. We aimed to investigate the incidence and management of acute adverse reactions (AARs) to Ultravist-370 and Isovue-370 in patients who underwent contrast-enhanced computed tomography (CT) scanning.Data from 137,473 patients were analyzed. They had undergone enhanced CT scanning with intravenous...
