chronic cobalt poisoning

It is used by the body in small amounts as part of vitamin B-12, to help make red blood cells and maintain the nervous system. Untreated chronic pain and depression are both known to contribute to cognitive changes and somatic symptoms. Cobalt has also been used as a treatment for anemia, because it stimulates red blood cell production. 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. For years the focus following hip replacement surgeries has been on the physical condition of the hip itself. from the Division of Toxicology at the University of Pittsburgh School of Medicine (Pittsburgh, PA, USA) proposed diagnostic criteria for arthroprosthetic cobaltism secondary to cobalt alloy-containing metal hip prostheses[18]. Too often the pursuit of a blockbuster medical device or new prescription drug clouds a corporate board’s better judgment. There are three basic ways that cobalt can cause poisoning. Also, it is well past time for medical device companies to slow down and return to more extensive testing of new medical products. Sci Total Environ. Further studies validating these new proposed criteria are not currently available. The patient's neurologic complaints are certainly found in patients with cobalt toxicity, but they are mostly subjective, non-specific, and when put in the context of the relatively low serum cobalt metal ion level, are unlikely to be the result of cobalt toxicity. Schaffer AW, Pilger A, Engelhardt C, Zwelmueller, et al. Devlin JJ, Pomerleau AC, Brent J, Morgan BW, et al. Signs and symptoms of cobalt poisoning can include visual You get this after contact with a low dose over a long time. 7. Cobalt is an essential element for health in animals in minute amounts as a component of Vitamin B12. BMJ 1967; 1: 544-545. This usually will only happen in industrial settings where large amounts of drilling, polishing, or other processes release fine particles containing cobalt into the air. If the whole blood cobalt metal ion concentration in these patients is greater than 7 �g/L, a second metal ion test should be performed three months later and the patient should be assessed for cardiac and neurologic symptoms[1]. However, other studies have demonstrated persistence of neurologic symptoms even after the hardware is removed[1]. 2008;389:259-269. 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]. 2008 Oct 23:69-73. 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). Mao X, Wong AA, Crawford RW. And clouded judgment hurts people. Post-mortem studies of the heart in these patients confirmed accumulation of cobalt within the myocardium. Quesada MJ, Marker DR, Mont MA. In 2010, the first published report of arthroprosthetic cobaltism specifically attributed to cobalt alloy-containing metal-on-metal hip prostheses was described[13]. Chronic arsenic poisoning is due to repeated or continuous exposure to arsenic compounds, which leads to an accumulation of arsenic in the body. The patient described in the preceding clinical vignette is an excellent example of a concerning medical topic emerging in the current news. Cobalt has also been used as a treatment for anemia, because it stimulates red blood cell production. Cobalt chromium poisoning is a risk for anyone with a metal on metal (MoM) hip replacement. He has even given it a name: Arthroplasty Cobalt Encephalopathy, or ACE. 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? Common signs and symptoms of Chromium Toxicity ingested orally include: Severe gastrointestinal … Lancet 369:542-544. Cobalt is an essential, transition group metal present in trace amounts in the human diet, notably in fish, vegetables, and drinking water. Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Metallosis is a type of metal poisoning that can occur as a side effect of joint replacement devices with metal components, such as metal-on-metal hip implants or some knee implants. Schirrmacher UO. Submitting a contact form, sending a text message, making a phone call, or leaving a voicemail does not create an attorney-client relationship. 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]. Instead, if there is a gradual increase in circulating cobalt metal ion concentrations or there are concerning systemic symptoms, the patient should be promptly evaluated by an orthopedic surgeon for appropriate further medical action. J Med Toxicol. This type of implant is an artificial hip socket that is created by fitting a metal ball into a metal cup. Finally, there is no current consensus regarding the management of patients with cobalt alloy-containing metal-on-metal hip prostheses and elevated circulating cobalt metal ion levels, and there is little information available regarding the clinical course of arthroprosthetic cobaltism from cobalt alloy-containing metal-on-metal hip prostheses. Chronic Effects (Noncancer): Cobalt is an essential element in humans and animals as a constituent of vitamin B 2. 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. What is Arthroplasty Cobalt Encephalopathy (ACE)? ACE symptoms usually occurred one year before hip symptoms (pain, weakness, clicking, loosening, etc.) Laboratory confirmation of elevated serum or whole blood cobalt metal ion levels due to an implanted prosthetic hip. Cobalt and chromium can be released as the metal ball grinds against the metal cup when a person walks or moves. Cobalt poisoning is a common problem in patients with artificial hips. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. Leavelle DE, editor. 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. An essential trace element, cobalt an cause serious adverse c health effects at high exposure levels. 8. One issue Dr. Tower discovered was that ACE could occur with lower readings of cobalt in the body. Toxins include organic solvents (with high blood-brain permeability) and metals (with sometimes poorly understood mechanisms of neural uptake). In addition, he noted that the patient lacked other symptoms of systemic cobalt toxicity including hypothyroidism and cardiomyopathy. A precise, unifying mechanism of cobalt toxicity remains unclear. Sunderman FW Jr, Hopfer SM, Swift T, Rezuke WN, et al. J Med Toxicol. Symptoms come on slowly and can include: 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]. In the United States, the FDA defines "symptomatic patients" as patients experiencing localized symptoms, such as pain or swelling at the hip, change in walking ability, and noise from the joint, after more than 3 months following implantation of the cobalt alloy-containing metal-on-metal hip prosthesis[17]. As the metal builds up in your body, you can get sick. Unfortunately, her story is one lived by the many who cope with neurological issues as a result of cobalt toxicity. A 2017 study in BMC Psychiatry looked at ten cases of metal-on-metal hip replacements. 2013 Jul 11 (ahead of print). Contrastingly, if a patient has subjective and objective clinical evidence of systemic cobalt toxicity, has elevated cobalt metal ion concentrations, and no history of a cobalt alloy-containing metal-on-metal prostheses, a diagnosis of cobalt toxicity may be more straightforward. ACE is meant to identify a brain disease or associated neurological symptoms caused by elevated levels of cobalt from a metal artificial hip. Case of cobalt poisoning. Cobalt chromium poisoning is a risk for anyone with a metal on metal (MoM) hip replacement. Cobalt is a chemical element with the symbol Co and atomic number 27. Although cobalt is an essential element in dogs, an excess of cobalt can be fatal if not treated right away. We are finding cobalt poisoning in too many patients with metal-on-plastic and metal-on-ceramic hips. It is an integral part of vitamin B12, and is required for oxygen transport in metabolism. The benefits touted by metal-on-metal prostheses is that there is less device wear since cobalt-alloy containing metal prostheses have a higher resistance to wear than polyethylene, a decreased risk of dislocation because of new designs and engineering modifications, and a decreased risk of device fracture[2-3]. Interestingly, the impetus for the inquiry leading to these recommendations was an increase in metal-on-metal hip device failure, not to address patients with systemic cobalt toxicity. Cobalt is a naturally occurring element in the earth’s crust. These patients also presented with severe neurologic and cardiac symptoms, hip pain resulting from periprosthetic metallosis, and elevated serum cobalt concentrations, up to 122 �g/L. But Dr. Tower has observed neurological problems in several patients with metal-on-plastic hips, or hips utilizing a ceramic ball with a metal cup. Instead, the toxicologist alluded to the fact that the patient was not taking his pain medication and was endorsing symptoms of worsening anxiety and depression, medical conditions he was diagnosed with prior to his bilateral hip replacements in 2008. The United Sates Food and Drug Administration (2013). Alexandersson R. Blood and urinary concentrations as estimators of cobalt exposure. The prognosis of Cobalt Poisoning is dependent on the amount of substance consumed, time between consumption and treatment, severity of the symptoms, as well as general health status of the patient. Cobalt poisoning is a common problem in patients with artificial hips. During this appointment, he reported symptoms of intermittent confusion, short-term memory loss, difficulty concentrating, poor attention, dysthymia, increased falling episodes, fatigue, and chronic headaches since his bilateral hip replacements in 2008. Witzleb WC, Ziegler J, Krummenauer F, Neumeister V, et al. Serum concentrations >1 mcg/L indicate possible environmental or occupational exposure, and concentrations >5 mcg/L are considered toxic. He notes that the onset of symptoms with metal on plastic or ceramic occurs more slowly, but the symptoms themselves can be just as severe. Vaping and Cobalt Poisoning. cobalt toxicity . It is a very small part of our environment and very small amounts are needed for many animals and humans to stay healthy.Cobalt poisoning can occur when you are exposed to large amounts of cobalt. Studies of whole-body retention of inorganic cobalt in physiologically normal adult human males after intravenous injection demonstrated that approximately 40% of the dose was eliminated within the first 24 hours, 70% by one week, after one month 20% was retained, and after one year 10% was retained[7-8]. When these criteria are applied to the currently published cases of arthroprosthetic cobaltism secondary to cobalt alloy-containing metal-on-metal hip prostheses, the circulating serum cobalt metal ion concentrations are typically very high, usually approaching 100 �g/L, before systemic cobalt toxicity is objectively identified. According to the CDC, "chronic exposure to cobalt-containing hard metal (dust or fume) can result in a serious … Since 2006, there have been increasing reports in the literature of patients with cobalt alloy-containing metal prostheses developing systemic symptoms of cobalt toxicity, termed athroprosthetic cobaltism[13]. Oral intake of Cr (VI) compound may cause Therefore, there are no current definitive conclusions regarding the association of suspected arthroprosthetic cobaltism with specific clinical, physical, imaging, or laboratory findings. In his discussion Dr. Tower noted that after nine of his patients had revision surgeries, seven patients no longer showed signs of being cobalt-positive, and five of those seven improved neurologically. 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. Although, I have focused on the hypothyroidism and cardiomyopathy, other things have been reported from chronic cobalt poisoning including pericardial effusions, deafness, optic nerve atrophy, and peripheral neuropathy. What is the Prognosis of Cobalt Poisoning? Cobalt(II) may become cobalt chloride or bind to proteins. 1972;222:451-459. Cobalt ions induce chemokine secretion in primary human osteoblasts. The heavy metal cobalt is used in making items like jet engines and diamond polishers. 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. Sci Total Environ. 2 Cobalt is employed industrially in certain grades of steel and in tungsten carbide tools, and cobalt compounds are used as pigments in paints. In general, improved case definitions, controlled studies, and improved surveillance are needed to fully elucidate the course of this relatively new disease and direct further investigations. 2012;23(1):50-58. He discovered that 57 were cobalt positive, meaning the cobalt urine test revealed 1 part per billion (ppb) or higher. Unfortunately, her story is one lived by the many who cope with neurological issues as a result of cobalt toxicity. However, caution must be applied when testing and interpreting cobalt levels in patients with cobalt alloy-containing metal-on-metal prostheses since these patients tend to have incidentally higher circulating cobalt metal ion concentrations, sometimes greater than 5 �g/L, but may not have symptoms of cobalt toxicity. Schirrmacher UO. The medical community has (slowly) accepted that MoM hips were a health problem and have moved away from their use. Cobalt toxicity can present with haematological, cardiovascular, immunological, gastrointestinal, endocrinological, dermatological, ophthalmological and neurological effects. occurred. The neurological symptoms that occur with cobalt metal poisoning include: Dr. Tower did a post-surgical study of his patients with artificial hips containing at least one component made from chromium/cobalt. 2010;92(17):2847-2851. Cardiovascular dysfunction: A notable toxic effect of cobalt exposure is a severe and often fatal cardiomyopathy. This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. The goal of total hip replacement is to maintain a functional joint while simultaneously delaying the need for surgical revision or replacement for as long as possible. 2012;432:210-215. Cobalt metal ion values are typically reported in units of micrograms/liter (�g/L). Toxins include organic solvents (with high blood-brain permeability) and metals (with sometimes poorly understood mechanisms of neural uptake). Essentially, they suggest that these patients should be followed carefully and specifically questioned regarding alterations in neurological, cardiac, and endocrine function. To this day, it is unclear whether elevated cobalt metal ion levels should be considered toxic in patients with cobalt alloy-containing metal-on-metal prostheses, especially if they are asymptomatic, since no clear correlation has even been made between cobalt concentration and physiologic effects (to be discussed later)[12]. Case of cobalt poisoning. It is also dependent on whether the toxic effects of cobalt are from an acute or chronic exposure Based on the most recent level, which is really only about 2-3 times the normal limit, the toxicologist was not convinced that this was consistent with cobalt toxicity. (1) 1 Chronic exposure to cobalt by inhalation … When inhaled through the lungs, usually in the form of inorganic cobalt and cobalt oxide in dust and welding fumes, there is systemic dissemination of cobalt metal ions through the lymphatic and vascular system[6]. For many years my clients with failing artificial hips have asked me about the health effects of high cobalt and chromium levels in the body. 1973;5852:527-529. This type of implant is an artificial hip socket that is created by fitting a metal ball into a metal cup. Therefore the 7 �g/L threshold was derived from a population reference range, and indicates a potential for periprosthetic soft tissue reaction/metallosis and a need for closer surveillance[1]. Eur J Orthop Surg Traumatol. In these patients, they advise to consider serial cobalt metal ion testing, but also strongly advise interpretation of these levels in the context of the patient's clinical symptoms, baseline renal function, and potential alternative sources of cobalt. 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). Rochester, MN: The Laboratories; 2001. The main objective of treatment is to eliminate the exposure to cobalt and to treat the systemic symptoms supportively, such as thyroid replacement therapy, beta-blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), diuresis, corticosteroid therapy, etc[1]. The neurological symptoms that occur with cobalt metal poisoning include: tremors J Orthop Res. Recently in November 2013, Pizon et al. Unfortunately, no. Dr. Tower found that patients could have serious neurological issues caused by cobalt with readings of 1 ppb. 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. Instead, government authorities in the United States and United Kingdom have released recommendations for management of both symptomatic and asymptomatic patients with cobalt alloy-containing metal-on-metal hip prostheses and elevated circulating cobalt metal ion concentrations. It has generally been accepted that cobalt readings below 4 ppb was not cause for concern, and some surgeons would not order further testing until the cobalt readings exceeded 7 ppb or even 10 ppb. Queally JM, Devitt BM, Butler JS, et al. Arthroprosthetic cobaltism: Neurological and Cardiac Manifestations in Two Patients with Metal-on-Metal Arthroplasty. The signs and symptoms of Chromium Toxicity depend on whether the exposure occurred through oral ingestion, chronic inhalation, or skin contact. Unfortunately, most neurologic symptoms are highly subjective, but some can be proven objectively, including optic nerve atrophy, audiometry-confirmed hearing loss, and abnormal neurologic function illustrated by electrodiagnostic studies such as an electroencephalograms (EEG) or electromyograms (EMG). Health risks of chronic exposure . Dr. Tower has concluded that this approach is wrong, or at least incomplete, and he has seen that often the first signs of trouble with hip replacement patients are neurological symptoms. Signs and symptoms of cobalt poisoning can include visual Therefore, the cobalt metal ion concentration value of concern is unknown. J Bone Joint Surg Br 2007; 89: 567-573. In the United Kingdom, the Medicines and Healthcare Products Regulatory Agency (MHRA) recommends following patients with cobalt alloy-containing metal-on-metal hip prostheses for cobalt toxicity symptoms at least annually for five years post-implantation[1]. There have been concerns, especially among younger patients, that the plastic cup in conventional hip prostheses undergo more wear and tear with time, and are more likely to require revision. Chronic persistent diffuse injury to the brain with clinical manifestations involving cognitive impairment. Cobalt poisoning is an intoxication brought on by having too much cobalt in the body. The concentration of cobalt, in particular, was remarkably high. At the time of revision increasing concentrations of the alloy elements cobalt, chromium, and molybdenum were measured in the serum and liquor. Remember I am not a doctor and this is not medical advice. The main objective in treating symptomatic patients with cobalt alloy-containing metal-on-metal hip prostheses is hardware revision or removal[1]. It happens when there’s friction between metal surfaces. Cobalt poisoning can manifest with symptoms of varying degrees of severity and can even cause death. Orthopaedic metals and their potential toxicity in the arthroplasty patient: a review of current knowledge and future strategies. But now a thoughtful surgeon is saying, “Hold up. It happens when there’s friction between metal surfaces. 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. I am a product liability lawyer with many clients who were injured by artificial hips containing cobalt and chromium. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. Cobalt ions induce chemokine secretion in primary human osteoblasts. 1999;37(7):839-844. Therefore, metal-on-metal bearings have gained widespread popularity and have been used extensively, especially among younger, still active patients. Symptoms usually arise after several years and may manifest as pneumoconiosis (with dyspnoea and cough secondary to interstitial fibrosis), an allergic alveolitis or occupational asthma. Sometimes, metal particles (cobalt) are released … Arch Environ Health. Learmonth ID, Case CP (2007) Metallic debris from orthopaedic implants. Over time, deposition of wear particles and metal ions in the joint space causes grey-black discoloration of the joint and elicits a localized chronic inflammatory response, findings referred to as metallosis. The symptoms of cobalt toxicity documented in the literature are variable, but typically involve derangements of endocrine, cardiac, and neurological function[1]: Endocrinopathy: The classic endocrinopathy associated with cobalt toxicity is hypothyroidism. J Bone Joint Surg Am. However, the patient's most recent serum cobalt metal ion concentration during his hospitalization was 3.1 �g/L, and even at its highest level was 11.4 �g/L.
