ORIGINAL ARTICLE Asian Pacific Journal of Allergy and Immunology Comparison of immediate hypersensitivity reaction rate according to the type of radiocontrast media Hye Jung Park,1* Hye Sun Lee,2 Sinae Kim,2 Chul Hwan Park3 Abstract Background: Various types of radiocontrast media (RCM), which can be substituted for each other, are used in clinical settings. However, data on comparisons of hypersensitivity reactions (HSR) based on types of RCM are lacking. Objectives: We aimed to compare HSR rates to facilitate the choice of appropriate RCM types. Methods: From January 2011 to December 2015, we retrospectively reviewed 209,027 clinical events involving seven different RCM in Gangnam Severance Hospital. We analyzed immediate HSR events using an internally developed adverse drug reaction reporting system. Furthermore, we defined risk factors for HSR, including RCM type. Results: During the 5-year study period, 209,027 RCM usage occurred in 97,374 patients. During that period, 108 HSR happened in 88 patients (0.05% events). The HSR rate for iodixanol (0.16%) was the highest, followed by that for iopamidol (0.08%), iopromide (0.04%), iobitridol (0.04%), ioversol (0.02%), ioxitalamic acid (0.01%), and iohexol (0.01%). Multivariate generalized estimating equation analysis showed age (odds ratio [OR], 0.980; 95% confidence interval [CI], 0.969-0.990; P < 0.001), urticaria (OR, 1.936; 95% CI, 1.003-3.737; P = 0.049), drug allergy (OR, 9.212; 95% CI, 5.353- 15.853; P < 0.001), iopamidol use (OR, 8.327; 95% CI, 1.129-61.401; P = 0.038, compared to iohexol), iodixanol use (OR, 18.780; 95% CI, 2.564-137.560; P = 0.004, compared to iohexol), and use in 2014-2015 (OR, 2.704; 95% CI, 1.780-4.108; P < 0.001) were significant HSR-associated risk factors. Conclusion: Among the RCMs, iodixanol (iso-osmolar RCM) and iopamidol (low-osmolar RCM) showed a significantly higher risk for immediate HSR than did other agents.

Gomi et al.14 compared the incidence of numerous studies. Non-ionic RCM were introduced to replace acute ADRs among five low-osmolar RCM including iomeprol, ionic RCM, which reduced the HSR rate.4,5 Moreover, the HSR iopamidol, iohexol, iopromide, and ioversol.
