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.

: Historically, the use of Iodinated Contrast Media (ICM) for diagnostic purposes, particularly radiography and computed tomography (CT), is well-known. Many of the ICM are included in the World Health Organization (WHO)’s List of Essential Medicines. Depending on the chemotype and the presence of ionizable functional group(s), the ICM are categorized in the ionic/nonionic monomers/dimers. The lipophilicity, aqueous solubility, viscosity and osmolality are major characteristics dictating their use for one procedure versus the other. Over last several decades, substantial advancement occurred in the design and development of novel ICM, solely to reduce their propensity to cause adverse effects. Given the nature of their acute usage, some of the agents with appreciable toxicity are still used. Understanding their chemistry aspects is crucial to appreciate, acknowledge and justify the usage of these extremely important torch-bearers of diagnostic agent’s class. The present review article presents an in-depth overview of the synthetic methods, therapeutic indications, potential adverse effects along with the commercial and environmental aspects of ICM. The safety and tolerability of these agents is a field that has gained significant importance, which is given due importance in the discussion.
