We investigated whether drug-related behaviors predicted antiretroviral therapy (ART) discontinuation among a cohort of injection drug users (IDU) in a Canadian setting. Cox regression analyses were used to investigate the impact of drug use patterns on rates of ART discontinuation among a sample of HIV-positive IDU in Vancouver, Canada between May 1996 and April 2008. In total, 408 HIV-positive IDU initiated ART during the study period, among whom 257 (63.0%) discontinued ART at least once. Rates of ART discontinuation were not significantly elevated among those who reported ongoing injection of heroin, cocaine, or other illicit drugs in comparison to those who reported not injecting drugs. However, public drug use was significantly predictive of ART discontinuation. Our findings may contribute to a reconsideration of the role of active drug use in determining retention in ART programs among IDU.
我们研究了在加拿大的一个注射吸毒者(IDU)队列中,与药物相关的行为是否会预测抗逆转录病毒治疗(ART)的中断。使用 Cox 回归分析来研究在 1996 年 5 月至 2008 年 4 月期间,加拿大温哥华的一组 HIV 阳性 IDU 中,药物使用模式对 ART 中断率的影响。在研究期间,共有 408 名 HIV 阳性 IDU 开始接受 ART,其中 257 名(63.0%)至少中断过一次 ART。与未注射毒品的人相比,报告持续注射海洛因、可卡因或其他非法药物的人中断 ART 的比率并没有显著升高。然而,公开的药物使用是 ART 中断的显著预测因素。我们的研究结果可能有助于重新考虑在 IDU 中,积极的药物使用在确定抗逆转录病毒治疗方案的保留率方面的作用。
