This review covers four peripheral alcohol abuse markers. Acetaldehyde adducts detect long-term abuse, while 5-hydroxytryptophol (5-HTOL) indicates recent alcohol consumption within 24 hours.

Area of Science:

  • Biochemistry
  • Toxicology
  • Clinical Chemistry

Context:

  • Alcohol abuse is a significant public health concern.
  • Accurate and timely detection of alcohol consumption is crucial for diagnosis and treatment.
  • Peripheral biomarkers offer potential for monitoring alcohol intake.

Purpose:

  • To review recently described peripheral biomarkers for alcohol abuse.
  • To differentiate the detection windows and applications of various alcohol abuse markers.

Summary:

  • Acetaldehyde adducts can detect alcohol abuse lasting several weeks, persisting even after withdrawal.
  • 5-hydroxytryptophol (5-HTOL) in urine reflects alcohol consumption in the preceding 24 hours, detectable after blood alcohol levels normalize.
  • Hyaluronic acid and beta-hexosaminidase activity are indicators of alcohol-induced liver damage rather than direct markers of intake.

Impact:

  • Acetaldehyde adducts serve as markers for chronic alcohol abuse.
  • Carbohydrate-deficient transferrin (CDT) is noted as a marker for recent alcohol abuse.
  • 5-HTOL provides a non-invasive method for assessing recent alcohol consumption.
