In an HIV-hepatitis B virus (HIV-HBV) coinfection cohort in Zambia, we piloted a qualitative point-of-care (POC) test for urine Ethyl glucuronide (uEtG), assessed concordance between uEtG and alcohol use disorders identification test-consumption (AUDIT-C), and identified epidemiological factors associated with underreporting (defined as uEtG-positivity with last reported drink > 7 days prior). Among 211 participants (40.8% women), there were 44 (20.8%) lifetime abstainers, 32 (15.2%) former drinkers, and 135 (64.0%) current drinkers, including 106 (50.2%) with unhealthy drinking per AUDIT-C. Eighty-seven (41.2%) were uEtG-positive including 64 of 65 (98.5%) who drank ≤ 3 days prior and 17 of 134 (12.7%) underreported, all of whom admitted to recent drinking when results were discussed. uEtG was moderately concordant with AUDIT-C. Past drinking (versus lifetime abstinence) and longer time on antiretrovirals (≥ 12 months) were associated with underreporting. These data support further use of POC alcohol biomarkers in HIV and hepatitis research and clinical settings.
在赞比亚的 HIV-乙型肝炎病毒 (HIV-HBV) 合并感染队列中,我们试点了一种即时尿液乙基葡萄糖醛酸苷 (uEtG) 的定性检测方法,评估了 uEtG 与酒精使用障碍识别测试-消费 (AUDIT-C) 的一致性,并确定了与漏报相关的流行病学因素(定义为 uEtG 阳性且最后一次报告饮酒时间在 7 天之前)。在 211 名参与者(40.8%为女性)中,有 44 名(20.8%)终生戒酒者、32 名(15.2%)曾经饮酒者和 135 名(64.0%)现在饮酒者,包括 106 名(50.2%)根据 AUDIT-C 诊断为不健康饮酒者。87 名(41.2%)uEtG 阳性,其中 64 名(98.5%)在过去 3 天内饮酒,17 名(12.7%)漏报,所有漏报者在讨论结果时都承认最近有饮酒。uEtG 与 AUDIT-C 中度一致。过去饮酒(与终生戒酒相比)和更长时间服用抗逆转录病毒药物(≥12 个月)与漏报相关。这些数据支持在 HIV 和肝炎研究和临床环境中进一步使用即时酒精生物标志物。
