how to detect ethylene glycol poisoning

Cases of permanent kidney damage, often requiring chronic dialysis or kidney transplantation, have been reported after severe poisoning. Ishwarlal Jialal, MD, PhD, FRCPath, DABCC, Department of Pathology and Laboratory Medicine, UC Davis Medical Center, Sacramento, CA. [21] There may be a slight risk of poisoning where mists or fogs are generated, although this rarely leads to poisoning as ethylene glycol causes irritation and coughing when breathed in, alerting victims to its presence. Disposing of used antifreeze only by taking to a service station. [46][47][48][49] The most significant long-term complication is related to the kidneys. Storing antifreeze in clearly marked original sealed containers, in areas that are inaccessible to pets. While five of the hospital visits involved kidney problems, doctors never thought to suspect ethylene glycol poisoning, prosecutors said. CNS depression begins soon after exposure, lasting for up to 12 hours after ingestion. [7] The most significant effect is accumulation of calcium oxalate crystals in the kidneys which causes kidney damage leading to oliguric or anuric acute kidney failure. The presence of a large osmolal gap supports a diagnosis of ethylene glycol poisoning. The glycolic acids contribute to central nervous system manifestations, mortality, and a significant metabolic acidosis (anion gap acidosis).3 These metabolites also contribute to significant renal tubular necrosis. In cats, this stage occurs 12–24 hours after consuming antifreeze; in dogs, at 36–72 hours after consuming antifreeze. The presence of calcium oxalate or hippurate crystals in the urine, together with an elevated anion gap or osmolal gap, strongly suggests ethylene glycol poisoning (Albertson 1999). 28). [7] The central nervous system is affected early in the course of poisoning as the result of a direct action of ethylene glycol. [6] Symptoms usually follow a three-step progression, although poisoned individuals will not always develop each stage. This test measures the level of ethylene glycol in the blood. The advantage of this automated assay over the GC method is a substantial decrease in labor costs and a significant reduction in turnaround times by approximately 10 hours. Ethylene glycol is poisonous. [2], Signs of ethylene glycol poisoning depend upon the time after ingestion. However, you'd have to think of antifreeze poisoning in the first place to think to do the test. L [28] Additionally, the presence of other alcohols such as ethanol, isopropanol, or methanol or conditions such as alcoholic or diabetic ketoacidosis, lactic acidosis, or kidney failure may also produce an elevated osmolal gap leading to a false diagnosis. Oxalic acid binds with calcium to form calcium oxalate crystals which may deposit and cause damage to many areas of the body including the brain, heart, kidneys, and lungs. Alternatively, the adverse side effects of fomepizole are minimal[clarification needed] and the approved dosing regimen maintains therapeutic concentrations without the need to monitor blood concentrations of the drug. [77] Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand. Ethylene glycol itself is not toxic, but it is metabolized in the animal's body to several extremely toxic chemicals that are responsible for its potentially lethal effects. These were generally flagged with a rate error. [9] Some people put antifreeze into their cabin's toilet to prevent it from freezing during the winter, resulting in toxicities when animals drink from the toilet. The bittering agent is thought to stop ingestion as part of the human defense against ingestion of harmful substances is rejection of bitter tasting substances. Also, assays for glycolic acid need to be more readily available because levels correlate with symptomatology and mortality. The antidotes for ethylene glycol poisoning are ethanol and fomepizole. It tastes sweet. McKay [64][68][69] Specifically, Mullins finds that bittering of antifreeze does not reduce reported cases of poisoning of preschoolers in the US state of Oregon. Ethylene glycol blood test. Also, an important observation is that there was no interference with fomepizole, commonly used for treatment of ethylene glycol poisoning.8 Juenke et al4 also performed patient sample comparison and showed excellent correlation with the “gold standard” method, GC-FID. D This depression appears similar to ethanol intoxication, but without the characteristic odor of alcohol. This damage can be identified in a serum biochemistry profile by increases in the metabolites creatinine and BUN (blood urea nitrogen) that are normally removed from the blood by the kidneys. The goal of pharmacotherapy is to prevent the formation of these metabolites. Most clinical laboratories are equipped to accurately quantitate ethanol levels, mainly by an enzymatic assay on an automated chemistry analyzer platform. [78], CS1 maint: DOI inactive as of December 2020 (. MA Poisoning of a raccoon was diagnosed in 2002 in Prince Edward Island, Canada. The best way to confirm ethylene glycol poisoning is by measuring the blood concentration of ethylene glycol. For ethylene glycol, the preferred method is GC–flame ionization detection (FID). The pharmacology, clinical presentation (including laboratory findings), and diagnosis of methanol and ethylene glycol intoxication are reviewed here. et al. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. It has been shown to be highly effective in the removal of ethylene glycol and its metabolites from the blood. FREE real person client care by email or phone Mon to Thu 9:00 AM – 4 PM ( MST) and Fridays 9:00 AM to 3:00 PM MST [12] A report prepared for the World Health Organization in 2000 stated that laboratory tests exposing aquatic organisms to stream water receiving runoff from airports have shown toxic effects and death (p. [9], Generally, if the person is treated and survives then a full recovery is expected. [55][56][57] Many cases of poisoning are the result of using ethylene glycol as a cheap substitute for alcohol or intentional ingestions in suicide attempts. [26] People receiving ethanol therapy also require frequent blood ethanol concentration measurements and dosage adjustments to maintain a therapeutic ethanol concentration. Letter to the Editor 111 REFERENCES 1. I-3). [76] Considering factors such as the "seasonal nature of releases, ambient temperatures, metabolic rates and duration of exposure", Environment Canada stated in 2014 that "it is proposed that ethylene glycol is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity". That is roughly 16 mL of 50% ethylene glycol for an 80 kg adult and 4 mL for a 20 kg child. Devleeschouwer However, these instruments and the needed expertise are not readily available in most clinical laboratories. Without oxalic acid formation, the nephrotoxic effects can be avoided, but the ethylene glycol is still present in the body. [73] Field studies in the vicinity of an airport have reported toxic signs consistent with ethylene glycol poisoning, fish kills, and reduced biodiversity, although those effects could not definitively be ascribed to ethylene glycol (p. In an effort to prevent poisoning, often a bittering agent called denatonium benzoate, known by the trade name Bitrex, is added to ethylene glycol preparations as an adversant to prevent accidental or intentional ingestion. It is important to recognize the signs that accompany ethylene glycol poisoning with your dog or cat. LA They have taste buds that detect sugars just like we do. [9] Small amounts of ethylene glycol may be contained in holiday ornaments such as snow globes. [7], Fomepizole is a potent inhibitor of alcohol dehydrogenase; similar to ethanol, it acts to block the formation of the toxic metabolites.

A definitive diagnosis of EG poisoning is made with a serum ethylene glycol level. [69] Additionally, another study by White found that suicidal persons are not deterred by the bittered taste of antifreeze in their attempts to kill themselves. [72] Numerous cases of poisoning have been reported since then, and it has been shown to be toxic to humans. "[74], In Canada, Environment Canada reports that "in recent years, management practices at Canada’s major airports have improved with the installation of new ethylene glycol application and mitigation facilities or improvements to existing ones. 12). The toxicity of ethylene glycol comes from its metabolism to glycolic acid and oxalic acid. Urine Fluorescence Using a Wood's Lamp to Detect the Antifreeze Additive Sodium Fluorescein: A Qualitative Adjunctive Test in Suspected Ethylene Glycol Ingestions. [2] The preferred antidote is fomepizole with ethanol used if this is not available. JM Urinary crystals result from. . We are aware of only 4 hospital laboratories in California that can perform this test on a \"stat\" basis. While there are differences between methanol and ethylene glycol poisoning, there is substantial overlap, and both the similarities and differences are described below. Ethylene glycol toxicosis is a type of poisoning that occurs after ingestion of antifreeze or other fluids containing the ingredient ethylene glycol. [4] Deaths from ethylene glycol have been reported as early as 1930. Although survival with medical treatment has occurred with doses much higher than this, death has occurred with 30 mL of the concentrate in an adult. The diagnosis of ethylene glycol poisoning should be considered in any people with a severe acidosis. [9] Other sources of ethylene glycol include windshield deicing agents, brake fluid, motor oil, developing solutions for hobby photographers, wood stains, solvents, and paints. 13). Ethanol Therapy for Ethylene Glycol and Methanol Toxicity Did you know? PI Grauer et al. Libeer Blackwell [52] In Australia there were 17 cases reported to the Victorian poison center and 30 cases reported to the New South Wales poison center in 2007. Additionally, as a side effect of the first two steps of metabolism, an increase in the blood concentration of lactic acid occurs contributing to lactic acidosis. [44] People who present early to medical facilities and have prompt medical treatment typically will have a favorable outcome. Urinary Crystals. [2] When broken down by the body it results in glycolic acid and oxalic acid which cause most of the toxicity. It does not have color or odor. A test to determine the blood levels can be done at some veterinary diagnostic laboratories or human hospitals. N [7] Seizures may occur due to a direct effect. [7] In this situation a helpful test to diagnose poisoning is the measurement of the osmolal gap. Ethylene glycol is converted by the liver into toxic byproducts that are damaging to the kidneys. A urine sample was sent for microscopy and showed multiple calcium oxalate monohydrate (COM) crystals, which supported the clinical suspicion of ethylene glycol poisoning. [42], Treatment for antifreeze poisoning needs to be started as soon after ingestion as possible to be effective; the earlier treatment is started, the greater the chance of survival. They both have a high boiling point, low vapour pressure, excellent heat transfer abilities and the ability to depress the freezing point of water, but ethylene glycol is a slightly more effective freezing point depressant. In this study, the modification by Juenke et al4 was to determine the slope of the line by measuring absorbance differences at several points, starting at a later time point than the original 2-point design. Thus, for methanol and isopropanol, gas chromatography (GC) is the confirmatory assay. ANTIFREEZE POISONING… VODKA AS AN ANTIDOTE? Wiley FH, Hueper WC, von Oettingen WF.The toxicity and potential dangers of ethylene glycol.J 3. Antifreeze Poisoning (Ethylene Glycol Poisoning) Drugs Scan (Comprehensive Drugs Scan ) Cyanide Poisoning Detection; We are ready to serve you NOW! [2] Other treatments may include sodium bicarbonate, thiamine, and magnesium. However, acidosis has a large number of differential diagnosis, including poisoning from methanol, salicylates, iron, isoniazid, paracetamol, theophylline, or from conditions such as uremia or diabetic and alcoholic ketoacidosis. J Poison control centers often use more than a lick or taste in a child or more than a mouthful in an adult as a dose requiring hospital assessment. FK TL [7], The kidney toxicity of ethylene glycol occurs 24 to 72 hours post ingestion and is caused by a direct cytotoxic effect of glycolic acid. JM Large anion gap acidosis is usually present during the initial stage of poisoning. Ethylene glycol in biological fluids can be determined by gas chromatography. Thus, for methanol and isopropanol, gas chromatography (GC) is the confirmatory assay. 245). Stage 2 (12 to 36 hours) where signs of "alcohol" poisoning appear to resolve, underlying severe internal damage is still occurring. Keeping pets and small children away from the area when draining the car radiator. [75] Detailed mitigation plans include storage and handling issues (p. 27), spill response procedures, and measures taken to reduce volumes of fluid (p. Antifreeze ingestions require rapid and accurate differential diagnosis to prevent fatal outcomes. This antidotal treatment forms the mainstay of management of ethylene glycol poisoning. [1], Early treatment increases the chance of a good outcome. Future studies will need to confirm the performance and usefulness of this automated testing in other clinical laboratories. Contaminated drinks were produced between July 2019 and … [14] Accumulation of glycolic acid in the body is mainly responsible for toxicity. The assay needs to be embraced by laboratorians to confirm its validity in identifying this serious form of intoxication, which constituted 2% of poisonings reported in the United States in 1999.9. [9] The treatment is generally the same, although vodka or rectified spirits may be substituted for pharmaceutical grade ethanol in IV injections. [3] Those affected are often adults and male. Similar to ethanol, it causes intoxication, followed by drowsiness or coma. [77] A report in 2000 stated that ethylene glycol was becoming less popular for aircraft deicing in the U.S., due to its reporting requirements and adverse environmental impacts (p. 213), and noted a shift to the use of propylene glycol (p. Martens [73] Another study found the toxicity to aquatic and other organisms was relatively low, but the oxygen-depletion effect of biodegradation was more serious (p. S Because hemodialysis will also remove the antidotes from the blood, doses of antidotes need to be increased to compensate. [7] People presenting with metabolic acidosis or seizures require treatment with sodium bicarbonate and anticonvulsives such as a benzodiazepine respectively. If a dark blue color forms in the pouch there is ethylene glycol present in the sample. Traditionally, gastric lavage or nasogastric aspiration of gastric contents are the most common methods employed in ethylene glycol poisoning. Wu J.J. Mackenzie, "Prevent Antifreeze Poisoning", in Laurie Halse Anderson, elevated blood concentration of potassium, EU classification of dangerous substances, "College of Veterinary Medicine: Pet Health Topics: Antifreeze Poisoning", "Ethylene glycol: an estimate of tolerable levels of exposure based on a review of animal and human data", "Antifreeze Poisoning in Dogs & Cats (Ethylene Glycol Poisoning)", "Severe ethylene glycol intoxication with multisystem failure", "Government of Canada: Environment Canada: Ethylene Glycol (Final Content)", "Cerebral computed tomography of ethylene glycol intoxication", "Ethylene glycol poisoning: toxicokinetic and analytical factors affecting laboratory diagnosis", "Fomepizole in the treatment of ethylene glycol poisoning", "Oklahoma Veterinary Medical Association: ASPCA answers questions about antifreeze poisoning", "Ethylene glycol ingestion treated only with fomepizole", "[Fatal chronic oxalosis after sublethal ethylene glycol poisoning]", "Experiences of the Czech toxicological information centre with ethylene glycol poisoning", "Ethylene glycol toxicosis in a free-ranging raccoon (Procyon lotor) from Prince Edward Island", "The Merck Veterinary Manual: Overview of Ethylene Glycol Toxicity", "General properties, irritant and toxic actions of ethylene glycol", "Concise International Chemical Assessment Document 22: Ethylene Glycol: Environmental Aspects", "Preliminary Data Summary: Airport Deicing Operations (Revised)", "Glycol Mitigation Strategies: The Canadian Approach". [7] It is only used in the presence of a toxic dose of another poison or drug. Wills JH, Coulston F, Harris ES, McChesney EW, Russell JC, Serrone DM. The modified assay, in addition to being precise (intra-assay coefficient of variation, <3.0%; interassay coefficient of variation, <8.0% ) and linear (up to 300 mg/dL), was also able to eliminate false-positives from a variety of interfering substances, including combinations of ethylene glycol, glycerol, propylene glycol, 2,3-butanediol, formic acid, n-propanol, isopropanol, acetone, methanol, ethanol, glycolic acid, polyethylene glycol, oxalic acid, glyoxal solution, glyoxylic acid, 1,2-butanediol, 1,4-butanediol, 1,3-propanediol, 1-butanol, 1,3-butanediol, DOT 3 brake fluid, and 1-octanol. [1] It may be drunk accidentally or intentionally in a suicide attempt. Wezorek C, Hodgman M, Dean B, Krenzelok E. Inadvertent ethylene glycol inhalation resulting in a toxic level. Costing US$1,000 per gram, an average course used in an adult poisoning would cost approximately $3,500 to $4,000. Oxalate binds calcium, leading to calcium oxalate crystals, which are deposited in many tissues but are most readily detected in the urine. Ethylene glycol also forms acidic chemicals in the body, which can change the body's acid/base balance and affect your nervous system, lungs, and heart,” a … [14][41] Hemodialysis also has the added benefit of correcting other metabolic derangements or supporting deteriorating kidney function. R ethylene glycol, but propylene glycol products are becoming more common. Hemodialysis is used to enhance the removal of unmetabolized ethylene glycol, as well as its metabolites from the body. The U.S. Environmental Protection Agency generally puts substances which are lethal at more than 30 g to adults in Toxicity Class III. for a 20 kg child. Juenke Klein-Schwartz The preferred assays are summarized in Table 1. [77] Large new airports may be required to collect 60 percent of aircraft deicing fluid after deicing. Dogs like sweet things. Juenke During metabolism, ethylene glycol breaks down to glycolic acid and then to oxalic acid by the action of alcohol dehydrogenase. [7] The use of these agents is based on theoretical observations and there is limited evidence to support their use in treatment; they may be of particular benefit in people who could be deficient in these vitamins such as those who are malnourished or alcoholic. The Catachem assay is based on a bacterial enzyme, glycerol dehydrogenase.5–7 This enzyme oxidizes ethylene glycol in the presence of NAD (nicotinamide adenine dinucleotide), generating NADH (the reduced form of NAD), resulting in an increase in absorbance at 340 nm, which is detected spectrophotometrically by automated chemistry analyzers. [50][51], Ethylene glycol poisoning is a relatively common occurrence worldwide. McMillin GA As the ethylene glycol is metabolized, animals often appear to recover from the direct effects of the poisoning only to rapidly deteriorate as glycolic acid concentration builds. [2] Treatment consists of stabilizing the person, followed by the use of an antidote. Testing for glycolic acid remains a clear advantage of GC, which can readily assay ethylene glycol and its toxic metabolite. [61][62] However, these numbers may underestimate actual numbers because not all cases attributable to ethylene glycol are reported to poison control centers. [7] The usefulness of gastric lavage has, however, been questioned, and it is now no longer used routinely in poisoning situations. Simply add your sample to the fill line, break the three ampules in order and wait 30 seconds for color to form. The disadvantage of fomepizole is that it is expensive. [60] In the United States there were 5816 cases reported to poison centers in 2002. [7] If hemodialysis is not available, then peritoneal dialysis also removes ethylene glycol, although less efficiently. [7], Other laboratory abnormalities may suggest poisoning, especially the presence of a metabolic acidosis, particularly if it is characterized by a large anion gap. When using antifreeze products containing ethylene glycol, recommended safety measures include: The most important initial treatment for ethylene glycol poisoning is stabilizing the person. Ishwarlal Jialal, MD, PhD, FRCPath, DABCC, Sridevi Devaraj, PhD, DABCC, Laboratory Diagnosis of Ethylene Glycol Poisoning: The Cup Is Half Full?, American Journal of Clinical Pathology, Volume 136, Issue 2, August 2011, Pages 165–166, https://doi.org/10.1309/AJCPTZO0HRPKVPWM. [37][38], Adjunct agents including thiamine and pyridoxine are often given, because they may help prevent the formation of oxalic acid. [13] The metabolic effects occur 12 to 36 hours post ingestion, causing primarily metabolic acidosis which is due mainly to accumulated glycolic acid. [64] These studies did not focus on poisoning of domestic pets or livestock, for example, or inadvertent exposure to bittered antifreeze among a large population (of non-preschool age children). [22] Ethylene glycol is not well absorbed through skin meaning poisoning following dermal exposure is also uncommon. Broussard If the lighted gunpowder sparked or [5] An outbreak of deaths in 1937 due to a medication mixed in a similar compound, diethylene glycol, resulted in the Food, Drug, and Cosmetic Act of 1938 in the United States, which mandated evidence of safety before new medications could be sold. In this way, Juenke et al4 were able to demonstrate that the modified kinetic parameters applied to the Catachem reagent system accurately distinguished between propylene glycol, 3-butanediol, and ethanol from the true measurement of ethylene glycol. Addressing the Challenges of Eosinophilia and Mastocytosis: Reactive Eosinophil Proliferations in Tissue and the Lymphocytic Variant of Hypereosinophilic Syndrome: Myeloid/Lymphoid Neoplasms Associated With Eosinophilia and Rearrangements of. https://en.wikipedia.org/w/index.php?title=Ethylene_glycol_poisoning&oldid=996426608, Toxic effects of substances chiefly nonmedicinal as to source, CS1 maint: DOI inactive as of December 2020, Articles with dead external links from September 2017, Articles with permanently dead external links, Short description is different from Wikidata, Articles with unsourced statements from July 2019, Articles lacking reliable references from October 2012, Wikipedia articles needing clarification from March 2012, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, Stage 1 (30 minutes to 12 hours) consists of. Thus, this assay is clearly advantageous to an emergency department physician dealing with this serious disorder. [58][59] Children or animals may be exposed by accidental ingestion; children and animals often consume large amounts due to ethylene glycol having a sweet taste. "[12] Since 1994, federal airports must comply with the Glycol Guidelines of the Canadian Environmental Protection Act, monitoring and reporting on concentrations of glycols in surface water. However, a normal osmolar gap does not rule out ethylene glycol exposure because of wide individual variability. [74], Once kidney failure has developed in dogs and cats, the outcome is poor. Ethylene glycol is a type of alcohol found in automotive and household products. et al. [65] In the United States, eight states (Oregon, California, New Mexico, Virginia, Arizona, Maine, Tennessee, Washington) have made the addition of bittering agents to antifreeze compulsory. Many laboratories have also achieved similar results using gas chromatography-flame ion detector, or GC-FID. The formation of acid metabolites also causes inhibition of other metabolic pathways, such as oxidative phosphorylation. [9], The most significant source of ethylene glycol is from aircraft de-icing and anti-icing operations, where it is released onto land and eventually to waterways near airports experiencing cold winter climates. Standefer [7] Both antidotes have advantages and disadvantages. [36], Following decontamination and the institution of supportive measures, the next priority is inhibition of further ethylene glycol metabolism using antidotes. Ethylene glycol poisoning was immediately suspected, because the patient had previously been hospitalized with similar symptoms after intake of antifreeze coolant. Inhalation effects of ethylene glycol with an average concentration in the air up to 140-200 mg / cc. Ethylene glycol is a colorless, odorless, sweet-tasting liquid commonly found in antifreeze, as well as in industrial agents. Ethylene glycol poisoning usually occurs due to ingestion, and its toxicity is mediated by its metabolites, glycolic acid, and oxalate. [23], As many of the clinical signs and symptoms of ethylene glycol poisoning are nonspecific and occur in many poisonings the diagnosis is often difficult. The major toxic alcohols that pose a risk to human health and for which measurement of levels is requested from the clinical laboratory include ethanol, ethylene glycol, isopropanol, and methanol. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures.

Thus, while the tests provide valuable clues to clinicians for differential diagnosis, measurement of the relevant alcohol is the most definite test to rule in or exclude a certain alcohol poisoning or ingestion. [25] Many hospital laboratories do not have the ability to perform this blood test and in the absence of this test the diagnosis must be made based on the presentation of the person. 2. Its adverse effects include intoxication, hypoglycemia in children, and possible liver toxicity. Litovitz Within 30 minutes of ingestion, they may resemble a person who has had too much to alcohol drink. This unit of measurement was derived by the British Navy when it was suspected that the rum ration was being diluted. Calcium oxalate crystalluria may be observed as early as 3 and 6 hr after ingestion in cats and dogs, respectively. As ethylene glycol is rapidly absorbed, gastric decontamination is unlikely to be of benefit unless it is performed within 60 minutes of ingestion. An increase in the osmolal gap is evident in the presence of all of the alcohols. [30][31], Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available, and are generally considered safer to use, as it possesses an unpleasant taste in contrast to the perceived "sweet" taste of toxic ethylene glycol-based coolants, and only produces lactic acid in an animal's body, as their muscles do when exercised. , assays for glycolic acid is then oxidized to glycolic acid remains clear!
