Gadolinium (Gd) usage in the Veterans Health Administration is increasing and patients with renal disease are frequently exposed. Gd is not entirely eliminated within 24 hours after administration, which may pose long-term adverse effects.
A Vietnam-era veteran aged > 70 years presented for evaluation of Gd-based contrast agent-induced chronic multisymptom illness. In the course of his routine clinical care, he was exposed to repeated Gd-enhanced magnetic resonance imaging studies. After his second Gd-based contrast agent exposure, he noted rash, pain, headaches, and hoarseness. Years after the exposure to the contrast agents, he continued to have detectable Gd in urine and serum.
Practitioners should be aware of long-term intracellular Gd retention (including the brain) as patients increasingly turn to consultants with concerns about Gd deposition disease. Data from patient advocates demonstrate that Gd is eliminated in intermediate and long phases, which may represent a multicompartment model. The commercialization of Gd use in imaging studies is outpacing the science addressing the long-term consequences of harboring this alien, toxic, nonphysiologic rare earth metal.
钆(Gd)在退伍军人健康管理局的使用正在增加,肾病患者经常接触到钆。钆在给药后24小时内不能完全清除,这可能会造成长期不良影响。
一名70多岁的越战老兵前来评估钆基造影剂诱发的慢性多症状疾病。在他的常规临床护理过程中,他多次接受钆增强磁共振成像检查。在第二次接触钆基造影剂后,他出现了皮疹、疼痛、头痛和声音嘶哑。在接触造影剂数年之后,他的尿液和血清中仍可检测到钆。
随着越来越多的患者因担心钆沉积病而向医生咨询,医生应意识到钆在细胞内长期潴留(包括在大脑中)的情况。患者权益倡导者提供的数据表明,钆在中、长期阶段被清除,这可能代表一种多室模型。钆在影像学研究中的商业化应用速度超过了研究这种外来、有毒、非生理性稀土金属长期后果的科学发展速度。
