NSF…what is it?
Nephrogenic Systemic Fibrosis (NSF), also known as nephrogenic fibrosing dermopathy (NFD), is a condition that, so far has occurred only in people with kidney disease. There is no convincing evidence that NSF is caused by a medication, a microorganism, or by dialysis. There have been no cases identified prior to early 1997. At this point it appears NSF is a systemic disorder with its most prominent and visible effects in the skin. For this reason, Nephrogenic Systemic Fibrosis has been suggested as an equivalent terminology in those previously diagnosed with NFD, and is preferred in that it more accurately reflects the current understanding of the disorder. Neither the duration of kidney disease nor its underlying cause are related to the development of NSF. Some patients with NSF develop skin tightening in the earliest stages of kidney disease, and others may have had kidney disease for years. Specific triggers for the development of NSF are still being investigated. Recent reports have strongly correlated the development of NSF with exposure to gadolinium-containing MRI contrast agents. GE healthcare is one manufacturer of gadolinium-containing MRI contrast.
