The main indication for this (apart from the inevitable renal failure of a late presentation) is a high osmolar gap. The result is a failure to convert ethylene glycol into glycoaldehyde; ethylene glycol remains in the circulation, gradually (and harmlessly) being excreted into the urine. Adolphe Wurtz (1856) "Sur le glycol ou alcool diatomique" (On glycol or diatomic alcohol), Comptes rendus, 43 : 199-204. The typical way to administer alcohol in such a situation is to give it via a central vein (it being such a good peripheral venous sclerosant that it is in fact routinely injected into varicose veins to destroy them). EG intoxication is the second most common cause of fatal poisoning in animals according to the American Association of Poison Control Centers. N Engl J Med 1981;304:976-8. There is a lot of good, thorough literature on the management of ethylene glycol toxicity. Clin Nephrol. Some redness and burning at the site were the only reported side effects. Then, you might feel slightly ill. As the glycolic acid begins to appear in the bloodstream, metabolic acidosis ensues and hyperventilation follows. Thus, ethylene glycol is metabolized by several oxidation steps eventually to yield oxalic acid (figure 7.56). Clinical toxicology 36 (7): 659–66. This effect rarely produces serious morbidity or death by itself.Acute renal failure as well as a severe anion-gap metabolic acidosis results from the metabolism of ethylene glycol into at least 4 distinct metabolites. In the parlance of the street cop, this equates to a blood alcohol level of 0.1%, twice the legal driving limit in Australia. It is not well absorbed through the skin; nor does it evaporate particularly well. Alcohol dehydrogenase, the same first step enzyme responsible for the metabolism of methyl and ethyl alcohols, slowly catalyzes conversion of EG to glycoaldehyde. Thus the pathological damage includes cerebral oedema, haemorrhage and deposition of calcium oxalate crystals. Of the various ways one can become acquainted with ethylene glycol, this is probably the most common. Anything over 1.0-1.5mg/kg is considered lethally toxic. Also, the intermediate metabolites of ethylene glycol have metabolic effects such as the inhibition of oxidative phosphorylation. 4-Methylpyrazole, or fomepizole as it is known, is basically a competitive antagonist to alcohol dehydrogenase. There is a complex metabolic pathway with multiple products, of which oxalic acid is the most dreaded. The imbalance in the level of this in the body is adjusted by oxidation to NAD coupled to the production of lactate. The chief diagnostic feature of ethylene glycol toxicity (apart from doing an actual ethylene glycol level) is calcium oxalate crystals in the urine. "Methanol and ethylene glycol poisoning: a case study and review of current literature." Glycolic acid (GA) and ethylene glycol (EG) are versatile two-carbon organic chemicals used in multiple daily applications. Competes with ethylene glycol for metabolism via alcohol dehydrogenase (ADH) enzyme. The lungs show oedema, and occasionally calcium oxalate crystals and degenerative myocardial changes may also occur. We found that strain JM37 grew rapidly with ethylene glycol as a … These toxic substances also affect the cardiopulmonary system and can cause renal failure. (See supplemental page for metabolic pathway figures for ethylene glycol and methanol). A Norfolk couple report that it tasted "horrible", though the husband finished his glass as a demonstration of his manliness. The degeneration of distal tubules may also be seen. Well. DEG has also been inappropriately substituted in pharmaceutical preparations for nontoxic constituents, resulting in more than a dozen epidemics of human poisoning, with resultant … Once past this window of time, absorption has already occurred. 1986 Apr;33(2):311-23. As it has a sweet. It does what ethanol would do, except it does so with great expense, and without ethanol intoxication. INTRAVENOUS INJECTION OF ALCOHOL BY DRUG INJECTORS: REPORT OF THREE CASES; "Glycolate kinetics and hemodialysis clearance in ethylene glycol poisoning. There are three recogniseable stages to ethylene glycol toxicity. Both alcohols are metabolised via alcohol dehydrogenase to their toxic metabolites. I cannot find the original paper, but a letter in response to it suggests one should sustain a blood ethanol concentration of 20 to 30 mmol/L (100 to 150 mg/dL). Anything over 0.1ml/kg will require treatment. Permanent optic atrophy may occur. It is first converted by alcohol dehydrogenase to glycoaldehyde, which is then metabolised to glycolic acid by aldehyde dehydrogenase. In contrast, the conversion of glycolic acid to glyoxylic acid is slower and is the rate-limiting step in the metabolism of ethylene glycol. It and its toxic byproducts first affect the central nervous system, then the heart, and finally the kidneys. Henderson, William R., and Jeffrey Brubacher. Thus the treatment of poisoning with ethylene glycol is a logical result of understanding the biochemistry of the toxicity. Common ethyl alcohol (ethanol) binds much more easily to ADH than ethylene glycol or methanol does. Effective Treatments for Peripheral Neuropathy, Carpal Tunnel Syndrome Holistic Treatments Ebook, 7 Useful Tips for Improving Your Mental Focus, How to Lose Weight From Your Stomach Fast, An alternative approach to perioral rhytides, Mental Impotence Holistic Treatments Ebook, This substance is a liquid used in antifreeze, paints, polishes and cosmetics. Otherwise, much of it is metabolized into hideous daughter-compounds, which are also excreted by the unhappy kidneys (which find themselves mangled by the process). Methanol and ethylene glycol poisonings share many characteristics both clinically and biochemically. Conduction disturbances and arrhythmias are to be expected, pulmonary oedema may result from myocardial depression (caused by the acidosis). Moreau CL, Kerns W, Tomaszewski CA, McMartin KE, Rose SR, Ford MD, Brent J (1998). Recent analyses demonstrated fundamentally different ways for oxidation of 1,2-propanediol and 2,3-butanediol.
