Abstract

Phosphatidylethanol (PEth) is a direct nonoxidative metabolite of ethanol that may be measured in clinical samples as a marker for monitoring alcohol consumption. It has been used in a wide variety of clinical and nonclinical settings; however, its investigation in relation to liver disease has been limited. This study aims at providing a short review on the applications and challenges for the incorporation of PEth testing in identifying alcohol intake in this patient population.

Graphical Abstract

Proposed hypothetical model of enhanced PEth formation in advanced liver disease. As liver disease progresses, the enzymatic activity of alcohol dehydrogenase and aldehyde dehydrogenase is decreased [1]. As a consequence oxidative metabolism of ethanol may be impaired yielding higher blood ethanol levels being shunted towards non-oxidative PEth pathway via phospholipase D (PLD) [2]. PLD has a greater affinity for ethanol than its usual substrate phosphatidylcholine [3], suggesting the possibility of intrinsic PEth formation in erythrocytes [4].
