Alcohol in the form of ethanol is found in alcoholic beverages, mouthwash, cooking extracts, some medications and certain household products. Ethyl alcohol poisoning generally results from drinking too many alcoholic beverages, especially in a short period of time. Targeting the NMDA receptor has proven to be more successful in delineating the mechanism underlying alcohol-induced memory impairment. Alcohol conveys its effect by inhibiting NMDAR-mediated LTP (Morris et al., 1986; Lovinger et al., 1989). These studies suggest that STEP plays a prominent role in alcohol-induced fear conditioning impairment. Recently a mouse strain mutant GluN1 subunit which is less sensitive to the effects of alcohol has been generated (den Hartog et al., 2013; Zamudio-Bulcock et al., 2018) but the effect of alcohol on cognition has not yet been determined. Additionally, genetic differences have been observed, as in the case of aldehyde accumulation.

Various mechanisms, stages of alcohol intoxication oxidative stress and impaired lipid metabolism, have been implicated in the pathogenesis of ALD. Our previous studies showed that nuclear factor erythroid-derived 2-like 2 is a master regulator of adaptive antioxidant response and lipid metabolism by using a liver-specific Nrf2 knockout (Nrf2-KO) mouse model. In the current study, an ALD model was developed by a Lieber-DeCarli liquid-based ethanol diet given to this Nrf2-KO mouse strain. We found that Nrf2-KO mice were quite sensitive to lethality from 6.3% ethanol diet. We thus decreased the ethanol concentration to 4.2% to obtain tissues to analyze the role of hepatic Nrf2 in the development of ALD.


In 1999, Brent et al. reported a multicenter, prospective, observational study of 19 patients who had ethylene glycol intoxication and metabolic acidosis (serum HCO3− 4 to 28 mEq/L) and were treated with fomepizole . Within a few hours of fomepizole therapy, serum glycolate levels fell and acid-base parameters improved.

  • Antidotal therapy with fomepizole or ethanol will inhibit ADH and prevent the formation of toxic metabolites in methanol and ethylene glycol poisoning.
  • In alcoholics, the severity of the clinical neurological impairment significantly correlated with hypometabolism in distinct brain regions (Gilman et al., 1990).
  • The Centers for Disease Control and Prevention estimates excessive alcohol use causes approximately 88,000 deaths annually in the United States.
  • It has been postulated that metabolism of formate is enhanced by folic acid, and given the lack of adverse effects, administration of folate as adjunctive therapy seems reasonable .
  • Documentation of high levels in contaminated medication has been reported, and this may be a valuable method of confirming exposure in large outbreaks.
  • Ethanol toxicity results from the ingestion of ethanol, usually in large quantities.
  • The biblical command to sanctify the Sabbath and other holidays has been interpreted as having three ceremonial meals with wine or grape juice, known as Kiddush.

If you have small children, store alcohol-containing products, including cosmetics, mouthwashes and medications, out of their reach. Use child-proof bathroom and kitchen cabinets to prevent access to household cleaners. Keep toxic items in your garage or storage area safely out of reach. Alcohol poisoning is a serious — and sometimes deadly — consequence of drinking large amounts of alcohol in a short period of time.

Reducing the burden from harmful use of alcohol

Unlike food, which can take to digest, alcohol is absorbed quickly by your body — long before most other nutrients. And it takes a lot more time for your body to get rid of the alcohol you’ve consumed. Even when you’re unconscious or you’ve stopped drinking, alcohol continues to be released from your stomach and intestines into your bloodstream, and the level of alcohol in your body continues to rise. In comparison to other toxic alcohols, isopropanol intoxication is usually managed supportively. Isopropanol is the only toxic alcohol that causes ketosis without acidosis. It is metabolised by ADH to acetone, without production of an anion gap acidosis.

How much do you have to drink to damage?

Any amount of alcohol can cause liver damage. Drinking more than two drinks per day consistently increases your risk of liver disease. However, the degree of liver damage varies greatly between individuals and there is no “safe” amount of alcohol to drink that cannot potentially cause liver disease.
