For more information about NSF, GBCAs, and Gadolinium, please see the Background section of our website. In our Survey of Chronic Symptoms of Gadolinium Toxicity, 100% of the participants reported Pain as one of their top symptoms. Allgemein / Gadolinium. ( Log Out / Change ), You are commenting using your Twitter account. They can be very intense soon after the MRI. Could it just be that the connection has not yet been made, and when considered together, all these facts might explain how patients’ symptoms are being caused by retained Gd from gadolinium-based contrast agents (GBCAs)? As you will see, Gadolinium Toxicity is not a new problem, but just one that should be recognized for the potential harm it can cause to everyone who retains gadolinium from the gadolinium-based contrast agents administered for MRIs. A recent study by Radbruch et al. Marckmann and Skov noted that the “clinical picture of NSF is diversified” and “it varies from one patient to another and it varies over time“. This study provides the first definitive evidence that GBCAs induce mitochondrial toxicity and cell death in cultured human neurons. Intense boring pain in bones or joints. www.GadoliniumToxicity.com. Copyright 2014-2020, All Rights Reserved. Interestingly, as you will see in my letter, many symptoms of SFN are the same as the clinical symptoms associated with nephrogenic systemic fibrosis (NSF), which makes sense to me since the cause is the same. Gadolinium Toxicity Symptoms. shedding light on the effects of retained gadolinium from Contrast MRI, September 22, 2020 12:19 pm / Leave a comment. Here we are in 2018, 21 years after a problem first became apparent and 12 years after it was linked to gadolinium-based contrast agents. Less serious side effects nausea, headache and dizziness. Can Symptoms of Gadolinium Toxicity be explained? Gadolinium Deposition Disease. With all of that published evidence of gadolinium’s toxic effects, I don’t believe it should come as a surprise to anyone that patients are reporting a wide range of symptoms after their MRIs with a gadolinium-based contrast agent – if anything, it seems it should be expected. 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. Epub 2018 Oct 1. 6. Burning, itching or severe sharp pai… Distal arm and leg skin/skin substrate thickening, discoloration, and pain. 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. Recently, patients who report that they suffer from chronic symptoms secondary to gadolinium exposure and retention created gadolinium-toxicity on-line support groups. Symptoms are categorized as "A Symptoms" which are symptoms distinctive for GDD (also other heavy metal toxicities), and "B Symptoms" which are symptoms that are commonly observed but may also be seen in a variety of other conditions. Would that be easily detected on histological examination of tissue, or blood tests? – a copy can be downloaded here: https://vdocuments.mx/nsf-clinical-picture-treatment.html, Sherry, A. D., Caravan, P., & Lenkinski, R. E. (2009). Arising in early stage (early on after GBCA): This can be any bones or any joints. Gadolinium Deposition Disease (GDD) refers to patients with gadolinium accumulation having normal kidney function that show painful symptoms within few hours or weeks or two months after exposure to Gadolinium based contrast agents (GBCAs). Read our full post and the study here. Gadolinium(Gd)-haltige Kontrastmittel (KM) werden seit 1988 in der klinischen MRT-Routinediagnostik weltweit eingesetzt. 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). Symptoms of Gadolinium Toxicity: Can their cause be explained? Symptoms of NSF are very similar to the symptoms of gadolinium poisoning. That is not a novel idea since it was suggested by some doctors in the past, including Dr. Jonathan Kay and his colleagues who said, “NSF neither originates in the kidney nor is caused by factors originating in the kidney”. Purpose: This study aims to describe the self-reporting symptoms experienced by individuals with self-reported normal renal function after gadolinium based contrast agent (GBCA) administration. Symptoms often develop within a month or so of the MRI. A healthy human body should naturally eliminate Gadolinium through the kidneys. The study involved 6 groups of 8 mice that were intravenously injected with one dose (1 mmol/kg body weight) of either a macrocyclic GBCA (gadoteridol, gadoterate meglumine, gadobutrol), a linear GBCA (gadodiamide or gadobenate dimeglumine), or saline. GDD sufferers describe it as a head pain, and unlike any other type of head-ache they have previously experienced. Second, the symptoms experienced by the patient after GBCA administration must be new, and not preexisting. The naming of GDD was a positive step for affected patients since it was the first time that gadolinium-related symptoms were recognized in patients with normal kidney function. Mai 2018 2. Gadolinium Deposition Disease (GDD) Can happen when gadolinium remains in the body for months or years. These symptoms include brain fog, cognitive deficits, burning pain throughout the body, bone pain, joint pain, skin changes and hair loss. Arising in the subacute stage (2 weeks +): This is very much like the principal features of NSF, but generally less severe. Gadolinium Deposition Disease (GDD) refers to patients with gadolinium accumulation having normal kidney function that show painful symptoms within few hours or weeks or two months after exposure to Gadolinium based contrast agents (GBCAs). Several of the papers cited by Marckmann were referenced in my 2012 letter to the FDA to make my point that gadolinium retention could happen to ALL patients and they could be adversely affected by it. Some have also described a persistent metallic taste or olfactory sensation. So the good news is that there are relatively few commercial uses for this dangerous metal and its compounds (1). Nephrogenic systemic fibrosis (NSF) Causes the skin and internal organs to harden. Our only advice is to consider symptom relief carefully, and do not try to be the hero who says “I … If that was the case in full-blown NSF, when the patient likely retained a lot more gadolinium, think how retaining less gadolinium might impact the clinical picture of patients with normal or near-normal renal function. As an affected patient with normal kidney function, I respectfully disagree. Muscle vibrations/twitching and pins and needles skin sensations generally reflect nerve disease (neuropathy). Isn’t it logical to think that lesser amounts of retained gadolinium could cause similar but perhaps less severe damage to various body systems in almost every patient who retains it? These symptoms include the following: Pain and a burning sensation in the lower arms and lower limbs – patients often describe the pain as burning or cutting Pain in the bones or joints In practice, the diagnosis of NSF therefore sometimes has to be based primarily on patients’ history of GBCA-exposures, subsequent appearance of otherwise unexplained symptoms from the skin, the limbs, or other organs, and the exclusion of relevant differential diagnoses”. Muscle vibrations (muscle fasciculations) and skin pins and needles/tingling (early on after GBCA). SIGNIFICANCE: Significant differences in gadolinium levels in bone and urine are observed between individuals experiencing symptoms of gadolinium toxicity and for those who are not exhibiting symptoms. Radbruch and his colleagues investigated changes of small fibers in the epidermis of mice as a potential cause of patient complaints about burning pain in their arms and legs after administration of a GBCA. shedding light on the effects of retained gadolinium from Contrast MRI. (more…). Gadolinium (Gd) Result 1.2 Reference Interval < 0.8 ... Gadolinium has no known biological role in humans. I believe many symptoms of gadolinium toxicity can be explained by Gd-induced small fiber neuropathy (SFN) and long-standing neuropathic pain. Retrieved from http://www.ncbi.nlm.nih.gov/pubmed/19744598 I believe the time has come for researchers and the FDA to acknowledge that evidence of gadolinium retention is evidence of harm…period. This condition is accompanied by symptoms that include severe physical pain and cognitive difficulties. This symptom complex should be expected. Letter to FDA about Gadolinium Toxicity from GBCAs. MRT & Gadolinium; Symptome; Hilfen; FAQ; Pharmalobby; Interessengemeinschaft; Blog & News; Helfen Sie! Gadolinium is normally excreted by the body through the kidneys, but kidneys functioning less than optimally have trouble getting rid of all of the gadolinium, so toxic levels build up in the body’s tissues and organs, including the brain. However, I am concerned that the diagnostic criteria for GDD could result in some patients who have been affected by retained gadolinium not being recognized and properly diagnosed. Gadolinium toxicity Symptoms include pain in the skin, bones, joints or head. As a possible additional marker for damage of small fibers, the appearance of terminal axonal swellings (TASs) was assessed. However, the lack of physical evidence and abnormal blood tests does not mean that harmful events have not taken place in patients’ bodies. July 20, 2020 6:21 pm / 5 Comments on Possible connection between GBCAs and Small Fiber Neuropathy. They said that the “unusual clinical presentation and nonspecific histology means that it may be very hard to come to the NSF diagnosis in some patients. It shouldn’t matter whether the evidence comes from unenhanced brain MR images, gadolinium detected in biopsy specimens, prolonged gadolinium excretion in urine specimens, or other testing methods. Absence of potential gadolinium toxicity symptoms following 22,897 gadoteric acid (Dotarem®) examinations, including 3,209 performed on renally insufficient individuals Eur Radiol. The symptoms in Gadolinium deposition disease are similar to nephrogenic systemic fibrosis (NSF) but are less severe. Those with gadolinium toxicity present symptoms shortly after a contrast MRI. Primer on gadolinium chemistry. Annals of the Rheumatic Diseases, 69(11), 1895–1897. An expansion of described symptoms for GDD. As Sherry et al. The authors made an important point that I believe should apply to all patients who have had MRIs with a GBCA. Die Symptome einer Gadolinium-Vergiftung sind vielfältig und häufig schwer zu deuten bzw. Nephrogenic systemic fibrosis: clinical picture and treatment. Nephrogenic systemic fibrosis can begin days to months after exposure to gadolinium-containing contrast. Some sufferers of gadolinium toxicity have also reported other symptoms, including gastrointestinal issues, such as diarrhea and abdominal pain, and cardiac issues such as abnormal heart rhythms. The FDA warning that came in 2015 was the one gadolinium toxicity advocates like Marcie were fighting for. The symptoms of Gadolinium Toxicity can include: Pain in the arms and legs Given that Gd has been shown to induce mitochondrial toxicity, interfere with ion channels, create neuronal hyperexcitability, and affect inflammatory processes, could Gd be affecting not only the part of the brain that controls many processes, but also peripheral and autonomic nerve endings, as well as dorsal root ganglia, to produce the many and varied symptoms that patients are experiencing? Materials and methods: This HIPAA-compliant, IRB-approved study consisted of an anonymous online survey of patients who believe that they suffer from gadolinium toxicity. These symptoms may represent part of the same process that is causing brain fog. Instead, here we are 9 years later, and the scope of the gadolinium retention problem still has not been widely recognized. symptoms of Gadolinium Toxicity. The literature also indicates that gadolinium is neurotoxic, nephrotoxic, and cytotoxic, it inhibits mitochondrial function, induces oxidative stress, triggers endoplasmic reticulum stress, increases vascular reactivity, induces macrophage apoptosis, causes fatty liver, is a potent blocker of calcium channels, and more. Posts about Symptoms written by Sharon Williams. Can Symptoms of Gadolinium Toxicity be explained? Any bones can have severe point pain, but rib pain is quite distinctive for the disease. If you would like to learn more about the symptoms of gadolinium toxicity, read our Survey of the Chronic Effects of Retained Gadolinium from Contrast MRIs report. What we don’t know is how much they retain. First, symptoms of GDD must start within minutes to one month after administration of a gadolinium-based contrast agent (GBCA). Depending on how much gadolinium someone retains and where it has been deposited in their body, the patient could experience many new symptoms or a few. I believe many symptoms of gadolinium toxicity can be explained by Gd-induced small fiber neuropathy (SFN) and long-standing neuropathic pain. Why should patients with normal kidney function be expected to be any different when they retain gadolinium? Even though impaired kidney function did not cause NSF, the focus remained on the “N” or nephrogenic part of NSF. Since the medical community believes these contrast dyes are harmless, many don’t trace their symptoms back on their timeline to their scan. You can absorb cesium by eating, drinking, breathing, or making skin contact with cesium or things containing its compounds. I/we knew they were wrong about that, but because of what had been said repeatedly in the published literature, patients with normal kidney function could not convince doctors that their symptoms were connected to the MRI with contrast that they had.
