Hypersensitivity reactions to iodinated contrast media are a pressing public health issue. Lack of understanding of pathogenetic mechanisms of such reactions leads to unjustified refuse of diagnostic and therapeutic procedures using iodinated contrast agents. Reactions of hypersensitivity to other iodine-containing medications are not a contraindication for use of contrast agents. Skin allergy tests are only performed in the patients who had a history of allergic reactions to iodinated contrast media. Usually it is possible to determine an alternative agent by means of skin tests. Premedication before a contrast-enhanced radiological examination has to be indicated to all patients with previous history of allergic disease.
Реакции гиперчувствительности на йодосодержащие рентгенконтрастные средства являются актуальной проблемой здравоохранения. Непонимание механизмов развития таких реакций приводит к необоснованным отказам от проведения диагностических и лечебных процедур с применением йодосодержащих контрастных средств. Реакции на другие содержащие йод препараты не являются противопоказанием к введению контрастов. Кожные пробы рентгенконтрастными веществами проводятся только пациентам, перенесшим реакцию на йодосодержащее контрастное средство в анамнезе. Обычно в результате тестирования удается подобрать альтернативный препарат. Пациентам с отягощенным аллергологическим анамнезом показано проведение премедикации перед рентгенконтрастным исследованием.Hypersensitivity reactions to iodinated contrast media are a pressing public health issue.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
