Nephrogenic Systemic Fibrosis

Nephrogenic systemic fibrosis (NSF), previously known as nephrogenic fibrosing dermopathy, is an idiopathic condition seen in patients with renal disease that is characterized by cutaneous sclerosis that can often result in contractures, pain, and functional disability as well as systemic complications. Recent reports have suggested a possible link with exposure to gadolinium, a commonly used radiocontrast agent. No current therapy has clearly demonstrated efficacy for NSF, although case reports suggest that extracorporeal photopheresis (ECP) may be of benefit. The purpose of this study was to explore the plausibility of a gadolinium linkage with NSF as well as to assess the efficacy of ECP in the treatment of a cohort of patients with NSF.
