Since the association between nephrogenic systemic fibrosis (NSF) and gadolinium contrast agents (Gd-CAs) was suggested in 2006, several experimental studies have been published to elucidate the role of these agents in the pathogenesis of NSF. Low stability Gd-CAs have a stimulant effect on human skin and fibroblasts in culture and modulate the production of collagen by these cells. Low stability agents have also induced NSF-like skin changes in a rat model with normal renal function after multiple repeat administrations. The role of the 5/6 subtotal nephrectomy rat model in investigating NSF remains under evaluation.
自2006年有人提出肾源性系统性纤维化(NSF)与钆对比剂(Gd - CAs)之间存在关联以来,已发表了多项实验研究以阐明这些药物在NSF发病机制中的作用。低稳定性Gd - CAs对培养中的人皮肤和成纤维细胞有刺激作用,并调节这些细胞的胶原蛋白生成。多次重复给药后,低稳定性药物在肾功能正常的大鼠模型中也诱发了类似NSF的皮肤变化。5/6肾大部切除大鼠模型在研究NSF中的作用仍在评估中。
