Table 1. Compounds potentially associated with toxicity in unrecorded alcohol<br />

diethyl phthalate (DEP) (0.08–0.15%) and PHMG (0.10–0.14%). PHMG is an effective antiseptic and is<br />

commonly used <strong>for</strong> suppression <strong>of</strong> hospital infection in <strong>the</strong> Russian Federation (16) and DEP denatures<br />

alcohol (17). Several o<strong>the</strong>r studies detected PHMG toge<strong>the</strong>r with DEP in disinfectants that were used as<br />

an ethanol source in poisoning cases in Russia (6, 16, 18). On <strong>the</strong> basis <strong>of</strong> clinical manifestations and<br />

laboratory findings <strong>of</strong> 579 poisoned patients, Ostapenko et al. (15) concluded that <strong>the</strong> cholestatic hepatitis<br />

(histologically different from conventional alcoholic liver disease) was caused by PHMG, while a history <strong>of</strong><br />

alcohol-induced hepatitis and cirrhosis contributed to a more severe course <strong>of</strong> <strong>the</strong> poisoning. O<strong>the</strong>r factors<br />

such as DEP or chronic viral hepatitis may have fur<strong>the</strong>r contributed to multifactorial liver damage. However,<br />

little is known about <strong>the</strong> alcohol consumed, which led to <strong>the</strong>se poisonings, <strong>the</strong> role <strong>of</strong> ethanol concentration,<br />

drinking patterns, or <strong>the</strong> role <strong>of</strong> unrecorded consumption (10, 19).<br />

CONCLUSIONS<br />

Recent research has shown that concerns about <strong>the</strong> toxicity <strong>of</strong> unrecorded alcohol were mostly exaggerated<br />

(4). For example, quantitative risk comparisons have shown that <strong>the</strong> potency <strong>of</strong> ethanol <strong>for</strong> liver toxicity is<br />

at least 5,000 times greater than that <strong>of</strong> ethyl carbamate (20). Ra<strong>the</strong>r than by reference to alcohol quality,<br />

liver cirrhosis rates could be better explained by <strong>the</strong> higher alcoholic strength <strong>of</strong> <strong>the</strong> unrecorded alcohol<br />

consumed, problematic drinking patterns, lower socioeconomic status and poor health status and <strong>the</strong><br />

interaction effect between <strong>the</strong>se factors (4).<br />

REFERENCES<br />

O<strong>the</strong>r components besides ethanol analysed in unrecorded alcohols have not been found in <strong>the</strong> vast<br />

majority <strong>of</strong> unrecorded alcohol samples at levels known to cause harm to health on a population scale (13).<br />

While several <strong>of</strong> <strong>the</strong> contaminants detected in unrecorded alcohol (especially copper and ethyl carbamate)<br />

could be hepatotoxic above certain thresholds, <strong>the</strong> typical human exposure is less than 1% <strong>of</strong> <strong>the</strong> threshold<br />

doses in rodents (13). There<strong>for</strong>e, while fur<strong>the</strong>r research in this area is certainly necessary, it would appear<br />

that <strong>the</strong> volume <strong>of</strong> alcohol consumption and/or drinking patterns ra<strong>the</strong>r than alcohol quality predominantly<br />

contribute to <strong>the</strong> differences in mortality (13). Unrecorded alcohol may contribute to this by <strong>the</strong> fact that<br />

unrecorded alcohol is <strong>of</strong>ten higher in strength and its lower price may fur<strong>the</strong>r contribute to drinking greater<br />

quantities (13).<br />

METHANOL AND PHMG: EXCEPTIONS TO THE RULE<br />

While unrecorded alcohol seldom contains substances more toxic than ethanol itself, <strong>the</strong> exception<br />

to <strong>the</strong> rule may be isolated outbreaks <strong>of</strong> methanol poisoning (14) as well as <strong>the</strong> occurrence <strong>of</strong><br />

polyhexamethyleneguanidine hydrochloride (PHMG), which was associated with an outbreak <strong>of</strong> acute<br />

cholestatic liver injury in Russia connected to <strong>the</strong> consumption <strong>of</strong> surrogate alcohol (15). In that case, <strong>the</strong><br />

alcohol that was consumed was a liquid intended <strong>for</strong> indoor disinfection, which contained ethanol (93%),<br />
