Nephrogenic systemic fibrosis was initially called nephrogenic fibrosing dermopathy (NFD) because it was thought to only affect the patient's skin cells. As the disease has become more widely studied, medical professionals have observed that the disease also affects internal organs, leading to the name change.
The disease was first described in 2000 and has since been linked to the use of gadolinium-based contrast agents in patients with renal insufficiency. Patients who develop NSF usually first experience a hardening and hyperpigmentation of the skin, often around the legs and arms. As the skin hardens, the patient experiences difficulty moving joints, such as knuckles, elbows and knees.
As the NSF progresses, the patient may eventually require a wheelchair because regular movements become almost impossible. Nephrogenic systemic fibrosis can also cause fibrosis (the formation of excessive fibrous tissue) around the patient's organs, which can be fatal.

Symptoms of NSF include pain, burning or itching sensations, changes in skin tone including a reddish tone or dark patches, edema, skin feeling more firm, joint stiffness, joint pain, weakness or limited motion in the limbs. According to the US Food and Drug Administration (FDA), patients who are about to receive a gadolinium-based contrast agent (GBCA) should be screened for acute kidney injury or chronic kidney disease prior to receiving the contrast agent.
Patients who have acute kidney injury or chronic kidney disease should not be given three specific GBCA drugs—Magnevist, Omniscan or Optimark—according to the FDA.
So far, NSF has not been reported in patients with normal kidney function.
