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.

The One

Background: Iodinated contrast media (ICM) are responsible for multiple side effects, especially hypersensitivity reactions. These reactions can either be authentic allergies, or non-allergic hypersensitivity reactions. Skin tests (prick and intradermal tests) are simple to perform and can be of great help, especially if the ICM need to be re-used. The aim of the study was to assess the characteristics of the patients in whom skin tests were performed, and the results of these tests. Methods: This is a retrospective study from June 2014 to June 2019. All included patients had at least one episode of hypersensitivity reaction to ICM and underwent skin tests. Results : We included 35 patients aged 18 to 85 years. The iopromide was the most implicated ICM. The reactions were mainly cutaneous (n=30) and immediate (n=27). The skin tests were negative, except for two patients. The reuse of ICM occured in 11 patients: 9 with an ICM other than the one suspected and two patients with the same ICM. Among these patients, 5 did not have any premedication. Two of them had a second hypersensitivity reaction, the first with another ICM and the second with the same ICM. Conclusion: One of the main pillars of allergic exploration is ICM skin testing, not only to prevent recurrence, but also to allow patients to benefit from ICM reuse, which are sometimes essential.

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.

Standard Design

IntroductionIodinated contrast media are commonly used in medical imaging and can cause hypersensitivity reactions, including rare but severe life-threatening reactions. Although several prophylactic approaches have been proposed for severe reactions, their effects remain unclear. Therefore, we aim to review systematically the preventive effects of pharmacologic and non-pharmacologic interventions and predictors of acute, hypersensitivity reactions.Methods and analysisWe will search the PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases from 1 January 1990 through 31 December 2019 and will examine the bibliographies of eligible studies, pertinent review articles and clinical practice guidelines. We will include prospective and retrospective studies of any design that evaluated the effects of pharmacological and non-pharmacological preventive interventions for adverse reactions of non-ionic iodinated contrast media. Two assessors will independently extract the characteristics of the study and intervention and the quantitative results. Two independent reviewers will assess the risk of bias using standard design-specific validity assessment tools. The primary outcome will be reduction in acute contrast media-induced hypersensitivity reactions. The secondary outcomes will include characteristics associated with the development of contrast media-induced acute hypersensitivity reactions, and adverse events associated with specific preventive interventions. Unique premedication regimens (eg, dose, drug and duration) and non-pharmacological strategies will be analysed separately. Average-risk and high-risk patients will be considered separately. A meta-analysis will be performed if appropriate.Ethics and disseminationEthics approval is not applicable, as this will be a secondary analysis of publicly available data. The results of the analysis will be submitted for publication in a peer reviewed journal.PROSPERO registration numberCRD42019134003
