| Abstract: |
Serious alcohol-associated hazards underscore the need to develop new biomarkers reflecting the biological changes caused by chronic alcohol use and predicting the risk of alcohol-related death. Oxidative stress is one mechanism of alcohol toxicity. The blood and urine redox status (total antioxidant capacity [TAC], total oxidative status [TOS], and oxidative stress index [OSI]) was assessed in 105 people who died a sudden death (controls), 47 people who died of alcohol overdose, and 102 people with alcohol dependency. TAC and TOS were determined utilizing the colorimetric method. Non-parametric tests were used for statistical analysis. Blood and urine TAC levels were significantly elevated in individuals both with alcohol dependency and alcohol poisoning compared with controls. TOS levels were elevated in the blood of both study groups compared with the control group, and significantly higher in patients with alcohol dependency compared with the group with alcohol poisoning. TAC in the blood highly correlated with blood alcohol content. Receiver operating characteristic (ROC) analysis showed that the blood TAC effectively discriminated between individuals with alcohol poisoning and alcohol dependency with high sensitivity and specificity. Our study confirmed impaired redox homeostasis in people with alcoholism and indicated the utility of TAC, TOS, and OSI as biomarkers of alcohol exposure. [ABSTRACT FROM AUTHOR] |
