We investigated the recently discovered association between gadolinium based magnetic resonance imaging contrast agents and the development of nephrogenic systemic fibrosis in patients with chronic kidney disease or acute kidney injury.
A systematic review of the PubMed database and publicly available patient databases was performed to characterize nephrogenic systemic fibrosis and its possible association with exposure to gadolinium based magnetic resonance imaging contrast agents.
Data from case series reports, nephrogenic systemic fibrosis patient databases, nephrogenic systemic fibrosis case reporting to the Food and Drug Administration after gadolinium contrast agent exposure and retrospective case control studies suggest a strong association between the use of gadolinium based magnetic resonance imaging contrast agents and the subsequent development of nephrogenic systemic fibrosis in patients with renal disease. These data also suggest that the risk of nephrogenic systemic fibrosis depends on the degree of renal dysfunction, dose of contrast agent, gadolinium contrast agent stability and severity of concomitant illness. Thus, the occurrence of nephrogenic systemic fibrosis after gadolinium contrast agent exposure may vary from negligible up to 2% to 5% in select high risk clinical situations.
Magnetic resonance imaging using gadolinium based contrast agents must be performed judiciously in patients with renal dysfunction, carefully weighing on a case by case basis the benefits of magnetic resonance imaging and the risk of nephrogenic systemic fibrosis as well as the disadvantages of undergoing alternative or foregoing imaging studies.
我们研究了最近发现的钆基磁共振成像造影剂与慢性肾病或急性肾损伤患者发生肾源性系统性纤维化之间的关联。
对PubMed数据库和公开可用的患者数据库进行系统评价,以描述肾源性系统性纤维化及其与接触钆基磁共振成像造影剂可能存在的关联。
来自病例系列报告、肾源性系统性纤维化患者数据库、钆造影剂暴露后向食品药品监督管理局报告的肾源性系统性纤维化病例以及回顾性病例对照研究的数据表明,使用钆基磁共振成像造影剂与肾病患者随后发生肾源性系统性纤维化之间存在密切关联。这些数据还表明,肾源性系统性纤维化的风险取决于肾功能不全的程度、造影剂剂量、钆造影剂稳定性以及伴随疾病的严重程度。因此,在某些高风险临床情况下,钆造影剂暴露后发生肾源性系统性纤维化的发生率可能从可忽略不计到高达2%至5%不等。
对于肾功能不全的患者,必须谨慎使用钆基造影剂进行磁共振成像,根据具体情况仔细权衡磁共振成像的益处、肾源性系统性纤维化的风险以及进行替代或放弃成像检查的弊端。
