Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function.
European guidelines classify a pre-existing decreased kidney function to be a risk factor of contrast-induced nephropathy in the following cases: [5]. Estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m 2 of body surface area before intra-arterial administration with first-pass renal exposure (not passing lungs or peripheral circulation before kidneys), or in the intensive care unit
While NSF is a severe form of disease, gadolinium deposition disease (GDD) is a mild variant with pain (e.g. headache), fatigue, and / or gadolinium depositions. [ 26 ] As a free solubilized aqueous ion, gadolinium(III) is highly toxic, but the chelated compounds are generally regarded as safe for individuals without kidney disease.
Gadodiamide is one of the main GBCA associated with nephrogenic systemic fibrosis (NSF), a toxic reaction occurring in some people with kidney problems. [6] No cases have been seen in people with normal kidney function. [7] A 2015 study found gadolinium deposited in the brain tissue of people who had received gadodiamide. [8]
In the early stages of the disease, this can result in mild symptoms such as reduced appetite or feelings of fatigue, but as CKD progresses, "complications like high blood pressure, heart disease ...
In patients with kidney failure, there is a risk of a rare but serious illness called nephrogenic systemic fibrosis (NSF) [61] that is caused by the use of gadolinium-based contrast agents. The disease resembles scleromyxedema and to some extent scleroderma. It may occur months after a contrast agent has been injected.
The contrast-enhancing effect is a result of the neutral complex of gadolinium and dihydroxy-hydroxymethylpropyl- tetraazacyclododecane-triacetic acid (butrol), which works to decrease differences in longitudinal relaxation times (T1) and differences in spin-spin or transverse relaxation times (T2).
Sodium thiosulfate has been observed to help in the treatment of a rare systemic fibrosis condition caused by gadolinium-based contrast media in patients with kidney failure. [19] The compound can also be used to measure the volume of extracellular body fluid and the renal glomerular filtration rate. [20]
