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 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 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 کاملExamination of patients suspected as having hypersensitivity to iodinated contrast media with leukocyte migration test.
In vivo tests may be used for the diagnosis of allergy to iodinated contrast media (ICM); however, the tests do not provide definitive diagnosis and are associated with risks for patients. Diagnoses based on in vitro tests are limited, and there are almost no relevant studies. Herein, the authors examined involvement of allergic reaction from a multilateral standpoint in 39 patients suspected o...
متن کاملThe Potential Utility of Iodinated Contrast Media (ICM) Skin Testing in Patients with ICM Hypersensitivity
Both immediate and delayed hypersensitivity reactions to iodinated contrast media (ICM) are relatively common. However, there are few data to determine the clinical utility of immunologic evaluation of ICM. To evaluate the utility of ICM skin testing in patients with ICM hypersensitivity, 23 patients (17 immediate and 6 delayed reactions) were enrolled from 3 university hospitals in Korea. With...
