Gadolinium Toxicity – Let’s not make the same mistake again

An Editorial by Hubbs Grimm
August 2018

(A pdf of this Editorial is available for download)

I want to talk about the unfortunate results of the early studies of gadolinium toxicity that defined NSF and the parallels I see today in the effort to define Gadolinium Deposition Disease (GDD).  I will also propose an alternative view of how to describe gadolinium toxicity in a way that reflects what we currently know and do not know that will recognize all patients who have been affected by retained gadolinium.

Before I begin, I want to be clear that I believe all those who have contributed in the past and those who are contributing today are doing so with the best of intentions and working from the basis of their experience and perspective.  But that does not mean that the result or proposals are necessarily best for meeting the needs of the people who are suffering from the toxic effects of gadolinium.

Gadolinium Toxicity: If not NSF, then what is it?

Editorial by Sharon Williams
August 2018

What difference does a name make?  Evidently, when you are naming a disease it can make a huge difference.  The name can limit the scope of medical research, and when it comes to gadolinium, it has the potential to exclude other patient populations who have been exposed to the same toxic metal.

In 1997, when a group of patients on dialysis developed what appeared to be a new skin disorder, it was called Nephrogenic Fibrosing Dermopathy (NFD).  When researchers later learned that the problem went well beyond the patients’ skin and caused a systemic disease process, the name was changed to Nephrogenic Systemic Fibrosis (NSF).  The word “nephrogenic” in the name caused doctors and researchers to focus on people with severe renal disease.  At the beginning, that made sense since the problem only had been seen in patients with end-stage renal disease (ESRD).  Later we learned more about the cause.

In 2006, nine years after NSF/NFD was first diagnosed, the connection was made between NSF and gadolinium-based contrast agents (GBCAs) administered for MRIs.  Even though impaired kidney function did not cause NSF, the focus remained on the “N” or nephrogenic part of NSF.  Patients with normal kidney function were being overlooked; however, they were not unaffected by retained gadolinium from GBCAs.

Gadolinium Toxicity – Status and Direction – August 2018

The two of us, Sharon Williams and Hubbs Grimm, have been working together on gadolinium toxicity related issues since 2012 and this website since 2014.  Since it affects us and our many new friends personally, coming to agreement on our “message” has not always been easy but we have done it.

Recently, out of frustration with lack of progress on matters related to gadolinium toxicity from MRI contrast agents, we wanted to do a post that was both reflective of where the medical community has been on this issue and where we believe it ought to go.  While we had similar ideas, we differed in how we wanted to convey the message.  So, we each worked on our own editorial and then we helped each other with the final copy as we have done many times in the past.

Tomorrow we will be posting two editorials about Gadolinium Toxicity.  While our approaches are different, this is not a dispute between us or an attempt to decide which is right and which is wrong.  Instead, it is two people, working together with great respect for each other, expressing their thoughts in an important discussion about something that affects countless other people.  We invite industry representatives to contribute to this discussion.

We hope you will read both editorials and take time to consider the important points we make.

Coauthors of The Lighthouse Project provide facts about Gadolinium Toxicity to FDA Advisory Committee

As coauthors of The Lighthouse Project, we have provided written comments about the toxic effects of gadolinium and gadolinium retention in patients with normal renal function to the FDA’s Medical Imaging Drugs Advisory Committee in advance of its September 8, 2017 meeting.  We will be making a brief oral presentation during the Open Public Hearing portion of the meeting which will be held at the FDA’s White Oak Campus in Silver Spring, Maryland.

Our comments are built around the following 6 major points that we cover in making the case that the FDA needs to take action regarding the use of Gadolinium-based Contrast Agents (GBCAs) administered for contrast-enhanced MRIs.

1. Medical literature documents toxicity of gadolinium and systemic implications.
2. The Risk Factors for adverse results are many.
3. NSF-Like Symptoms in patients with normal renal function.
4. Gadolinium from GBCAs does not clear the body in a few days, or even in a few months, allowing plenty of time for the Gd ion to dissociate from the chelate.
5. Underreported Symptoms from Contrast MRIs is a serious problem.
6. There is evidence of clinical implications of gadolinium deposition.

Our detailed comments can be found here:  Comments-from-Lighthouse-Project-FDA-2017-N-1957 .  We also included the following supporting materials:

We will report back later about our experience at the FDA Advisory Committee Meeting.
