Gadolinium Toxicity – A Disease of Degrees

Why does a Gadolinium Toxicity diagnosis have to be full-blown NSF (Nephrogenic Systemic Fibrosis) or nothing at all?  Patients with normal kidney function have been trying to get an answer to that question for years now, but for some reason no one is listening.

NSF, which can occur when someone with severe kidney disease retains large amounts of Gadolinium, is probably the worst manifestation of Gadolinium Toxicity.  But what happens to people who retain less Gadolinium?  Couldn’t those people also be adversely affected, but perhaps to a lesser degree than full-blown NSF?

We believe Gadolinium Toxicity is a “disease of degrees” which can manifest itself in many ways depending on how much Gadolinium someone retains.  Since free Gadolinium is toxic, it would seem that the severity of each person’s symptoms will likely depend on the total amount of Gadolinium retained from the administered Gadolinium-based Contrast Agent.

Iceberg ahead!

So why am I talking about an iceberg on the Gadolinium Toxicity website?  Let me explain.

Not long after I started researching NSF and Gadolinium in early 2010, I saw a reference to an editorial by Dr. Henrik Thomsen of Denmark that had been published in 2008.  The title was, Is NSF Only the Tip of the “Gadolinium Toxicity” Iceberg?  The title caught my attention and really made me think.  It took me a while, but I finally managed to find the editorial.  After reading it, I had more questions than answers.

It seems that in the early 1990s, there was already concern about the stability of the nonionic linear GBCAs, and the macrocyclic agents were found to be significantly more stable in serum.  It was known that transmetallation with other metal ions in the body was more apt to occur with the DTPA-based chelates, and when transmetallation occurs it results in the toxic Gadolinium ion remaining in the body.  Dr. Thomsen asked, “Why were nonionic linear chelates chosen instead of macrocyclic chelate?”  That is a very good question.

For those of us in the U.S., a better question might be, why did it take the FDA longer to react than the European Medicines Agency (EMEA) and the Japanese authorities?  (more…)

A Perspective on Gadolinium Toxicity and NSF

As you read more of the published articles about NSF, GBCAs and gadolinium, you will find a lot of confusing and at times conflicting information.  One thing I realized while doing my research is that it is important to consider when the article was published.  It wasn’t until 2006 that the connection was made between NSF and GBCAs, and as time has gone on some of what was said in the earlier articles has been further evaluated which resulted in new facts emerging.
