Clinical Criteria for Gadolinium Deposition Disease has been revised

On May 12, 2018, Dr. Richard Semelka revised the primary clinical diagnostic findings for Gadolinium Deposition Disease (GDD).  While the revision is being made sooner than anticipated, Dr. Semelka said it is based on well-informed recommendations from “patient experts” on the disease, and observations from 2 physician sufferers.  There are 5 symptoms that stand out to Dr. Semelka as critical diagnostic findings for GDD.  It is imperative that individuals have at least 1 of the symptoms, but he prefers to see 4/5 to make certain of the diagnosis.  Note that a 24-hour gadolinium urine test, performed 30 days or more after an MRI with a gadolinium-based contrast agent (GBCA), is still part of the diagnostic criteria for GDD.

The revised main clinical criteria for Gadolinium Deposition Disease, as described by Dr. Semelka are:

  1. Intense burning of the skin and skin substrate.Arising in early stage (early on after GBCA): This can be an all over feeling in the body, but often may be localized to the trunk region or distal extremities.
  2. Intense boring pain in bones or joints. Arising in early stage (early on after GBCA): This can be any bones or any joints. Often the joints may be peripheral but can also be large joints like the knee or hip. Any bones can have severe point pain, but rib pain is quite distinctive for the disease.
  3. Brain fog. Arising in early stage (early on after GBCA): Many terms have been used for this: mental confusion sounds more scientific, but brain fog gets the point across well and succinctly.
  4. Muscle vibrations (muscle fasciculations) and skin pins and needles/tingling (early on after GBCA). These symptoms may represent part of the same process that is causing brain fog. Muscle vibrations/twitching and pins and needles skin sensations generally reflect nerve disease (neuropathy).
  5. Distal arm and leg skin/skin substrate thickening, discoloration, and pain. Arising in the subacute stage (2 weeks +): This is very much like the principal features of NSF, but generally less severe. Instead of woodiness, doughiness; instead of redness, pinkness; instead of extreme joint contractures, stiffness of joints and decreased range of motion. This symptom complex should be expected.

Television Coverage of Gadolinium Toxicity on Full Measure

Sharyl Attkisson, five-time Emmy Award winner, and recipient of the Edward R. Murrow investigative reporting award, featured Gadolinium Toxicity in her June 11 edition of Full Measure.  Chuck Norris and his wife Gena Norris both talked about her struggle with her related symptoms that resulted in them spending over $1,000,000 on special care.

Our own Sharon Williams was also featured in the segment, both for her own symptoms and for her advocacy including letters to the FDA in starting in 2012 and the maintenance of this website..

Y0u can see a video of the program and read the dialogue here:

Study is first to report Gadolinium Toxicity in Patients with Normal Renal Function

Presumed Gadolinium Toxicity in Subjects with Normal Renal Function – A Report of 4 Cases”, is a landmark paper which documents the first presumed cases of gadolinium toxicity.  Richard C. Semelka, MD, Radiologist at the University of North Carolina at Chapel Hill, and his colleagues are the authors.  This is the first study to describe a series of patients with normal renal function who developed symptomatology lasting beyond the immediate post-injection period after the administration of a gadolinium-based contrast agent (GBCA).

Two subjects were assessed at 2 months and at 3 months after GBCA administration (early stage), and 2 subjects were assessed at 7 years and 8 years after GBCA administration (late stage).  Clinical features were similar between subjects, and included central torso pain (all), peripheral arm and leg pain (all), clouded mentation (2), and distal arm and leg skin thickening and rubbery subcutaneous tissue (one early and both late subjects).  All subjects had evidence of gadolinium retention ranging from one month up to 8 years after disease development.

Regarding clinical findings, the authors note that “these 4 individuals showed features that resemble and are observed in NSF patients”.  “Specifically, the glove-and-sock pattern of pain (seen in all patients) is essentially universally seen in NSF, and central torso pain (seen in 3 patients) is seen with some frequency, but not universally, in NSF patients.  Skin thickening and doughiness of the hands was seen in the 2 subjects with late-stage disease and is also described as a feature that progressively develops with NSF.”  They also noted that “headache and clouded mentation are vague and non-specific clinical symptoms; but they had new onset in 2 subjects”. While numerous recent studies report gadolinium deposition in the brain, no histopathological changes have been documented yet. They point out that a compound may be neurotoxic without being associated with histopathological signs.

These clinical features are comparable to the symptomatology reported by Burke et al, in which the most common self-reported symptoms included bone/joint pain and head/neck symptoms including headache, vision change, and hearing change (77.6% each). (more…)

Initial publication of symptoms of gadolinium toxicity

The results of a 9 question survey about gadolinium exposure and related symptoms in patients with normal renal function were reported in an article by Burke et al titled Self-reported gadolinium toxicity: A survey of patients with chronic symptoms.  The survey provides the initial description in the medical literature of patients with normal renal function who self-described toxicity related to administration of gadolinium-based contrast agents (GBCAs).  There were 50 respondents to the anonymous online survey.  All 50 respondents (100%) received gadolinium-based contrast with an average of 4.2 doses.  All 50 attribute their symptoms to gadolinium exposure.

Thirty-three (66%) subjects described the onset of symptoms immediately following GBCA administration and 16 (32%) within 6 weeks.  The most common symptoms included bone/joint pain and head/neck symptoms including headache, vision change, and hearing change.  Headache and bone/joint pain was described by more than 75% of the cases.  Skin changes were seen in approximately 60% of respondents.

Other symptoms reported include: flu-like symptoms (30.6%); digestive symptoms described as nausea, vomiting, diarrhea (46.9%); chest symptoms described as difficulty breathing (42.9%); generalized whole body symptoms (30.6%); and other (75.5%).

The findings of the survey showed that subjects with normal renal function might develop disease following administration of the majority of GBCAs including macrocyclic agents.

Despite the limitations of the survey, the authors said that it was their opinion “that there most likely is toxicity associated with GBCA administration in patients with normal renal function”.  They concluded that, “at the very least, this study highlights the need to further investigate the subject of patients with normal renal function who complain of severe long-lasting symptomatology following GBCA administration”.

My thoughts –
When Hubbs Grimm and I released the findings of the online symptom survey that we conducted in early 2014, we noted that the results presented in our paper should stimulate further professional investigation into gadolinium retention in all patient populations including those with normal renal function.  It is good to see that the medical community is now looking into the issue of gadolinium retention in patients with normal renal function further.

Our paper, Gadolinium Toxicity – A Survey of the Chronic Effects of Retained Gadolinium from Contrast MRIs can be found in the Research section of our website.
