| Background: The analysis of ethanol in bio-samples is an important method for determination of acute alcohol use/abuse both in clinical and forensic toxicology. In forensic cases, it is known that micro-organisms involved in the postmortem putrefaction process can produce alcohol and when the body has been traumatized. In clinical setting, post-ingestion time has a critical role for determination of alcohol level in biological fluids and the ethanol has been decreased during post-ingestion period, especially in chronic alcohol abusers. From this view, new biomarkers have been studied for evaluation of acute and chronic ethanol use/abuse in clinical and forensic cases. In this article, the role of each biomarker in determination of alcohol use/abuse was reviewed. Methods: We searched the PubMed and Google Scholar databases for articles about biomarkers of ethanol use/abuse with words “Alcohol”, “Ethanol”, “Biomarker”, “Abuse”, “Forensic” and “Clinical” from 1975-2014. Results: In postmortem cases, alcohol concentrations in blood, urine and vitreous depending on the status of the body. Urine and vitreous analysis may also be helpful, particularly in conjunction with blood. If none of these specimens is available, resort can be made to other organ and tissue samples but there are difficulties in both methodology and interpretation of results relating any alcohol present to ingested ethanol. Ethanol in gastric contents generally indicates recent ingestion, but the rapid absorption of ethanol and postmortem diffusion from the stomach may limit the usefulness of analysis of gastric contents. It is possible to measure parameters which are associated with or indicate ethanol consumption. Recently, ethyl glucuronide (EtG), 5-hydroxytryptophol (5-HTOL), gamma- glutamyltransferase (GGT), mean corpuscular volume (MCV) of erythrocytes and aminotransferases were found to have some applications in the clinical and medico-legal settings for determination of alcohol use/abuse history in acute and chronic states. Conclusion: 5-HPTOL and EtG can be considered as new biomarkers for determination of alcohol use/abuse in clinical and medico-legal settings. | ||
