Abstract

Alcohol use disorder (AUD) screening frequently involves questionnaires complemented by laboratory work to monitor alcohol use and/or evaluate AUD-associated complications. Here we suggest that measuring aldehyde-induced DNA and protein adducts produced during alcohol metabolism may lead to earlier detection of AUD and AUD-associated complications compared with existing biomarkers. Use of aldehyde-induced adducts to monitor AUD may also be important when considering that approximately 540 million people bear a genetic variant of aldehyde dehydrogenase 2 (ALDH2) predisposing this population to aldehyde-induced toxicity with alcohol use. We posit that measuring aldehyde-induced adducts may provide a means to improve precision medicine approaches, taking into account lifestyle choices and genetics to evaluate AUD and AUD-associated complications.

摘要

酒精使用障碍(AUD)的筛查通常涉及问卷和实验室工作,以监测酒精使用情况和/或评估与 AUD 相关的并发症。在这里,我们提出,与现有的生物标志物相比,测量酒精代谢过程中产生的醛诱导的 DNA 和蛋白质加合物可能会更早地发现 AUD 和与 AUD 相关的并发症。当考虑到大约有 5.4 亿人携带乙醛脱氢酶 2 (ALDH2) 的遗传变异,使这部分人群在饮酒时易受到醛诱导的毒性影响时,使用醛诱导的加合物来监测 AUD 可能也很重要。我们假设,测量醛诱导的加合物可能提供一种方法来改善精准医学方法,考虑到生活方式的选择和遗传因素来评估 AUD 和与 AUD 相关的并发症。
