摘要
目的:综述碘造影剂(ICM)过敏样反应发生机制研究进展。方法:参考国外相关文献,从膜效应、补体系统激活、缓激肽释放、Ig-E介导的抗原抗体反应、T细胞介导的免疫反应这5个方面,对ICM过敏样反应发生机制研究进行综述。结果和结论:ICM过敏样反应中绝大多数属于类过敏反应,真正的过敏反应很少,因此皮肤试验假阴性概率高,大规模推广造影前进行皮试意义不大。
Objective: To summarize the progress on pathophysiology of hypersensitivity reactions induced by iodinated contrast media.Methods: The data of mechanism of hypersensitivity reactions induced by iodinated contrast media (ICM) domestically and internationally in recent years was collected and analyzed.Results and conclusion:Most hypersensitivity reactions of ICM are non-allergic reactions, the real allergic reactions are few, so false negative result of skin test often happens and promoting skin test before using the ICM is of slighlt significance.
