Association between leptin levels and doses of clomethiazole during alcohol withdrawal: a pilot study.

Aims: The issue of leptin as a putative state marker of alcohol use and its role in craving has been raised in the last few years. Recently, a strong GABA-ergic modulation of leptin was postulated. The aim of the pilot study was to examine leptin levels in correlation with the strongly GABA-mimetic active substance clomethiazole.

Phosphatidylethanol: normalization during detoxification, gender aspects and correlation with other biomarkers and self-reports.

Phosphatidylethanol (PEth) is a direct ethanol metabolite, and has recently attracted attention as biomarker of ethanol intake. The aims of the current study are: (1) to characterize the normalization time of PEth in larger samples than previously conducted; (2) to elucidate potential gender differences; and (3) to report the correlation of PEth with other biomarkers and self-reported alcohol consumption. Fifty-seven alcohol-dependent patients (ICD 10 F 10.
