关于目前药物使用与艾滋病毒疾病进展和病毒学抑制之间的关联,研究结果不一致。药物使用通常通过自我报告历史使用情况来衡量。最好能客观地衡量目前的药物使用情况。在这项横断面研究中,我们通过计算机辅助自我访谈(CASI)和即时尿液药物筛查(UDS)评估了225名HIV感染患者的药物使用情况,并评估了当前药物使用与病毒学抑制之间的相关性。大约一半(54%)的参与者UDS呈阳性,CASI的自我报告率较低(42%)(Kappa评分= 0.59)。根据UDS,36.0%的人对大麻呈阳性,25.8%的人对可卡因呈阳性,7.6%的人对阿片类药物呈阳性,2.2%的人对甲基苯丙胺或苯丙胺呈阳性。与病毒学抑制(血浆HIV RNA <50拷贝/mL)相关的因素是白种人(P = 0.03)、较高的CD 4计数(P < 0.01)、当前使用抗逆转录病毒治疗(ART)(P < 0.01)和UDS阴性(P < 0.01)。在178名当前ART使用者中,阳性UDS与病毒学抑制的可能性较低显著相关(P = 0.04)。UDS与CASI在检测大麻和可卡因等常用药物方面具有良好的一致性。常规门诊访视时的UDS可提供“实时”预后信息,以优化管理。
There have been inconsistent findings on the association between current drug use and HIV disease progression and virologic suppression. Drug use was often measured using self-report of historical use. Objective measurement of current drug use is preferred. In this cross-sectional study, we assessed drug use through Computer-Assisted Self Interviews (CASI) and point-of-care urine drug screen (UDS) among 225 HIV-infected patients, and evaluated the association between current drug use and virologic suppression. About half (54%) of participants had a positive UDS, with a lower self-reported rate by CASI (42%) (Kappa score = 0.59). By UDS, 36.0% were positive for marijuana, 25.8% for cocaine, 7.6% for opiates, and 2.2% for methamphetamine or amphetamine. Factors associated with virologic suppression (plasma HIV RNA <50 copies/mL) were Caucasian race (P = 0.03), higher CD4 count (P < 0.01), current use of antiretroviral therapy (ART) (P < 0.01), and a negative UDS (P < 0.01). Among 178 current ART users, a positive UDS remained significantly associated with lower likelihood of virologic suppression (P = 0.04). UDS had good agreement with CASI in detecting frequently used drugs such as marijuana and cocaine. UDS at routine clinic visits may provide “real-time” prognostic information to optimize management.
