GE Healthcare, a part of General Electric, makes Omniscan, a dye that is used in MRIs (magnetic resonance imaging) and MRAs (magnetic resonance angiography). For most people, the dye leaves the body after being used in testing, but for others – particularly those with chronic kidney disease – it has been shown to stay in the body causing nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy (NFD).
What is NSF/NFD?
Nephrogenic systemic fibrosis (NSF) and nephrogenic fibrosing dermopathy (NFD) are conditions that involve hardening of the skin to a degree that the victim’s internal organs can be damaged, they could lose mobility or even die. NSF/NFD was not discovered until 1997; however, estimates of those who have the disease have been reported anywhere from 200 to 400 worldwide. As of yet, there is no known cure for the disease.
Symptoms of NSF/NFD
According to an alert published by the Food and Drug Administration (FDA), the symptoms of NSF/NFD include:
- For the skin: burning or itching, reddened or darkened patches; and/or skin swelling, hardening and/or tightening
- For the eyes: yellow raised spots on the whites of the eyes
- For the bones, joints and muscles: joint stiffness; limited range of motion in the arms, hands, legs, or feet; pain deep in the hip bone or ribs; and/or muscle weakness
The Administration recommends that anyone who thinks they may have NSF/NFD to have a skin biopsy.
FDA issues warning
The FDA recently issued a warning for Omniscan and four other dyes that are used in MRIs and MRAs. Although each is marketed under a different name, the primary ingredient in all of these drugs is gadolinium. The four other dyes being investigated are:
- Optimark
- Magnevist
- Multihance
- Prohance
The FDA is continuing to investigate these dyes, which continue to be marketed, and has issued this warning:
While FDA conducts its investigation, the following recommendations are being provided to health care providers and patients:
- Gadolinium-containing contrast agents, especially at high doses, should be used only if clearly necessary in patients with advanced kidney failure
- It may be prudent to institute prompt dialysis in patients with advanced kidney dysfunction who receive a gadolinium contrast MRI/MRA.
