Abstract

BACKGROUND: The objective of this study was a review of published studies utilizing measurement of fatty acid ethyl esters (FAEE) in meconium as biomarkers for prenatal alcohol exposure. METHODS: We completed a literature search of PubMed using the terms meconium, fatty acid ethyl esters, biomarkers, and prenatal alcohol exposure. We included only peer reviewed studies utilizing analysis of meconium for the presence of FAEE in humans through the year 2007. RESULTS: We found 10 articles reporting on original research examining the relationship of FAEE from meconium and prenatal alcohol exposure (PAE). The 10 articles used six different PAE assessment strategies and four different analytical techniques for determining FAEE endpoints. The articles included 2,221 subjects (range 4 to 725) with 455 (20.5%) subjects identified as exposed using the methods stated in the articles. FAEE levels above the studies' respective cutoffs were reported for 502 (22.6%) subjects. CONCLUSIONS: The accurate identification of alcohol‐exposed pregnancies represents a significant challenge in the development of FAEE detection cutoffs to maximize the sensitivity and specificity of the test. We present several options for the improvement of exposure assessment in future studies of FAEE as biomarkers for PAE. Birth Defects Research (Part A), 2008. © 2008 Wiley‐Liss, Inc.
