Health risks of chronic exposure . 2012;23(1):50-58. Common signs and symptoms of Chromium Toxicity ingested orally include: Severe gastrointestinal … Cobalt poisoning is a common problem in patients with artificial hips. Some of the mechanisms proposed include inhibition of crucial enzymes in mitochondrial oxidative phosphorylation, inhibition of thyroid iodinase, inhibition and competition with calcium binding and signaling, generation of reactive oxygen species, and direct cytotoxicity[1, 6]. 2006;77(5):697-704. When ingested, cobalt is rapidly absorbed from the small intestine, but the bioavailability is incomplete and variable[6]. However, there have been recent safety concerns regarding these prostheses, including excessive revision rates, local reactions to the prosthetic device, and high circulating metal ion levels in patients, which have led to product recalls, a medical device alert, and issuance of clinical guidelines by the United States' Food and Drug Administration (FDA). There are three basic ways that cobalt can cause poisoning. These questions usually arise after clients get blood work done and the test reveals abnormally high metal levels. With chronic systemic exposure, cobalt accumulates in tissue, again primarily the liver and kidney, and the cobalt level will be elevated in the serum, whole blood, and urine[9]. The medical community has (slowly) accepted that MoM hips were a health problem and have moved away from their use. Cobalt is a chemical element with the symbol Co and atomic number 27. The preferred method of testing is inductively coupled mass spectrometry for metal ion value determination, and the typical patient specimens tested include serum, whole blood, or urine. Conventional total hip prostheses are composed of a metal head that fits into a plastic, polyethylene cup. This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. For example, a notable historical example of cobalt toxicity is the cohorts of patients given cobalt chloride nearly 40 years ago to treat refractory anemia. Schirrmacher UO. 1988;43:299-303. The friction releases tiny metal particles into your bloodstream that could trigger a hypersensitive immune response in your body. A 2017 study in BMC Psychiatry looked at ten cases of metal-on-metal hip replacements. J Bone Joint Surg Br 2007; 89: 567-573. Pritchett JW. Following cessation of the chronic exposure, the concentration of cobalt decreases by 51±21% and 66±29% in … The more commonly reported value for cobalt metal ion concentration is the serum value, which is considered to be reflective of the extracellular fluid levels. But we need to start looking much more closely at the things we put into our bodies, whether it’s a Twinkie, a sleeping pill, or a metal artificial hip. The Data on Cobalt Poisoning and Neuropsychiatric Complications. Laboratory confirmation of elevated serum or whole blood cobalt metal ion levels due to an implanted prosthetic hip. November 3, 2016: (National Institute of Health) Seven substances added to 14th Report on Carcinogens Cobalt and cobalt compounds that release cobalt ions* in the body are being listed as reasonably anticipated to be a human carcinogen. Quesada MJ, Marker DR, Mont MA. 3. ACE is meant to identify a brain disease or associated neurological symptoms caused by elevated levels of cobalt from a metal artificial hip. Med J Aust. Also, it is well past time for medical device companies to slow down and return to more extensive testing of new medical products. If you are reading this article, you probably already know that cobalt and chromium are two metals used in the construction of most metal-on-metal (MoM) artificial hip systems. 2013 Jul 11 (ahead of print). At least two test-confirmed symptoms that are consistent with cobalt toxicity, i.e comprehensive neuro-cognitive testing, EMG, and/or formal ophthalmologic evaluation. Therefore, the final recommendations for this patient were that he be re-evaluated by his pain specialist, undergo extensive psychiatric testing, and have his hips re-assessed by orthopedic surgery. Cobalt poisoning is a common problem in patients with artificial hips. Essentially, they suggest that these patients should be followed carefully and specifically questioned regarding alterations in neurological, cardiac, and endocrine function. Smith T, Edmonds CJ, Barbaby CF. Chronic Toxic Encephalopathy . Sunderman FW Jr, Hopfer SM, Swift T, Rezuke WN, et al. There are no established indications for chelation therapy[1]. Therefore, metal-on-metal bearings have gained widespread popularity and have been used extensively, especially among younger, still active patients. B-Chronic Toxicity 1-Non-Occupational Intoxication : Endemic outbreaks of cardiomyopathy with mortality rates up to 50% have been described among heavy consumers (up to 10L/day) of cobalt-contaminated beer giving an exposure of a few milligrams per day. Arsenic is a type of carcinogen that’s gray, silver, or white in color. Contributed by Jessica Dwyer, MD and Octavia Peck Palmer, PhD, http://www.fda.gov/MedicalDevices/ProductsandMedicalProcedures/ImplantsandProsthetics/MetalonMetalHipImplants/default.htm. What is Arthroplasty Cobalt Encephalopathy (ACE)? Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. 2012;432:210-215. Following cessation of the chronic exposure, the concentration of cobalt decreases by 51�21% and 66�29% in the blood and urine, respectively[10]. The effects of the cobalt alloy hips were life-altering for Frances. Unfortunately, no. Absorption and retention of cobalt in man by whole-body counting. A precise, unifying mechanism of cobalt toxicity remains unclear. The clinical emergence of cobalt cardiomyopathy seems to require the coexistence of one or more cofactors, particularly a low-protein diet, thiamine deficiency, alcoholism, and hypothyroidism. Vaping and Cobalt Poisoning. cobalt toxicity . Remember I am not a doctor and this is not medical advice. Cobalt metal ion values are typically reported in units of micrograms/liter (�g/L). Studies following patients with arthroprosthetic cobaltism have demonstrated symptom improvement and declining circulating cobalt metal ion levels after removal of the implanted hardware, especially in patients with endocrinopathies and cardiomyopathy. Pizon AF, Abesamis M, King AM, Menke N. Prosthetic Hip-Associated Cobalt Toxicity. However, other studies have demonstrated persistence of neurologic symptoms even after the hardware is removed[1]. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. Submitting a contact form, sending a text message, making a phone call, or leaving a voicemail does not create an attorney-client relationship. Cobalt poisoning is a common problem in patients with artificial hips. When metal components grind together, as they naturally do when a MoM artificial hip is implanted in a person, very small metal particles can be released into the tissue and the bloodstream. Arch Environ Health. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. Oral intake of Cr (VI) compound may cause Acute poisoning is likely to occur through the oral route, whereas chronic poisoning is mainly from inhalation or skin contact [Meditext 2005]. Since these reports, DePuy Orthopaedics, Inc (Warsaw, IN) recalled their ASRTM metal-on-metal bearings because of a five year-prosthetic failure rate of more than 12% due to metallosis[3]. 09: Signs Your Artificial Hip May Be Defective, Aqueous Film-Forming Foam (AFFF) and Cancer: What You Need to Know, Physical Therapist: Problems with Metal-on-Metal Hip Failures (Part 3), Physical Therapist: What It Feels Like When Artificial Hips Fail (Part 2), Physical Therapist Discusses Hip Replacement Surgery, Recovery (Part 1). It has, however, been noted that tungsten carbide appears to modify the toxicity of cobalt and that cobalt alone does not have the same potent toxic effects. As the metal builds up in your body, you can get sick. Cobalt, Chromium, and Nickel Concentrations in Body Fluids of Patients with Porous-Coated Knee of Hip Prostheses. occurred. In addition, he noted that the patient lacked other symptoms of systemic cobalt toxicity including hypothyroidism and cardiomyopathy. Yet, more importantly, these patients with cobalt alloy-containing metal-on-metal hip prostheses that require revision surgeries due to metallosis have elevated circulating cobalt levels and may be at risk for systemic cobalt toxicity. For years the focus following hip replacement surgeries has been on the physical condition of the hip itself. Their criteria are defined as: The authors explain that these criteria are not a means to evaluate for prosthetic hardware failure, but are a means to specifically identify systemic cobalt toxicity by eliminating potentially subjective clinical symptoms. Signs and symptoms of cobalt poisoning can include visual It’s caused when the metal wears and introduces cobalt into the bloodstream. Increased Blood Cobalt and Chromium After Total Hip Replacement. One issue Dr. Tower discovered was that ACE could occur with lower readings of cobalt in the body. However, this practice was discontinued after some patients developed systemic symptoms of cobalt toxicity. It happens when there’s friction between metal surfaces. ACE symptoms usually occurred one year before hip symptoms (pain, weakness, clicking, loosening, etc.) Coleman RF, Herrington J, Scales JT. Cobalt is also component of cyanocobalamin also known as vitamin B12, which is widely consumed. Yet, even if a patient is symptomatic and highly suspicious for arthroprosthetic cobaltism, there is inadequate information provided by the FDA to guide clinical decision making because no consensus has been reached in regard to treatment of these patients. Learmonth ID, Case CP (2007) Metallic debris from orthopaedic implants. Hard metal workers (involved, for example, in grinding metals) and soldiers with embedded shrapnel may be exposed to the risk of long-term tungsten exposure. You can swallow too much of it, breathe too much into your lungs, or have it come in constant contact with your skin. Dr. Steven Tower, an orthopedic surgeon in Alaska, recently gave a fascinating (and alarming) talk about the many neurological problems he has observed in hip patients with elevated cobalt levels in the body. Cobalt toxicity can present with haematological, cardiovascular, immunological, gastrointestinal, endocrinological, dermatological, ophthalmological and neurological effects. Too often the pursuit of a blockbuster medical device or new prescription drug clouds a corporate board’s better judgment. According to the CDC, "chronic exposure to cobalt-containing hard metal (dust or fume) can result in a serious … Schaffer AW, Pilger A, Engelhardt C, Zwelmueller, et al. So, does the patient described in the previous clinical vignette have arthroprosthetic cobaltism secondary to his bilateral cobalt alloy-containing metal-on-metal hip prostheses? It is an integral part of vitamin B12, and is required for oxygen transport in metabolism. I am a product liability lawyer with many clients who were injured by artificial hips containing cobalt and chromium.
