Background: About 95% of consumed ethanol is metabolized by oxidative pathways. Less than 1% is metabolized via nonoxidative pathways: glucuronidation, sulfation, and the formation of fatty acid esters of ethanol. In neonates, the glucuronidation pathway has been reported to be underdeveloped but matures with age. This work compared the test results of patients' random urine samples submitted to our facility for ethyl glucuronide (EtG) and ethyl sulfate (EtS) measurements across pediatric and adult populations. Methods: Test results (n = 63 498) from urine samples tested for EtG and EtS by quantitative liquid chromatography-tandem mass spectrometry at our facility were utilized for this study. EtG and EtS concentrations were compared across the age partitions 0 to 17 years (pediatric), 18 to 80 years (adult), and 81 to 100 years (geriatric). Eight pediatric patients from a tertiary academic hospital contributed clinical context via abstracted clinical information. Results: Across the individual age partitions, 60% to 65% of patients had both EtG and EtS present in urine. Approximately 5% to 10% of patients had only EtG, and 25% to 35% had neither metabolite present. The lowest percentages (<1.5%) had EtS present in the absence of EtG. Markedly, no pediatric patients had only EtS present; compared to the adult population, this was statistically significant (Fisher exact test, P = 0.025). Conclusions: From the data presented in this work, EtG is more prevalent relative to EtS in urine samples of patients assessed for ethanol exposure. [ABSTRACT FROM AUTHOR] |
