丁丙诺啡治疗在所有阿片类药物使用障碍(OUD)患者中并不同样有效。两项回顾性研究表明,在非裔美国人(AAs)中,δ阿片受体基因的多态性rs678849调节了舌下丁丙诺啡的治疗效果。 我们在127名AA和327名欧洲裔美国人(EA)的24周OUD治疗研究中检查了rs678849作为缓释皮下丁丙诺啡制剂(BUP-XR)反应的调节剂。参与者被随机分配接受:(1)BUP-XR,每月注射300 mg,2次,然后每月300 mg或每月100 mg,持续4个月,或(2)每月注射体积匹配的安慰剂。广义估计方程logistic回归分析按人群组检验了治疗(BUP-XR vs安慰剂)和基因型组(rs678849*CC vs CT/TT)对每周尿液药物筛查(UDS)的主要和相互作用效应。 在AA中,安慰剂组阿片类药物阳性UDS的发生率高于BUP-XR组(对数比值比= 1.67,95% CI = 0.36,2.98),但没有治疗效应的基因型(P = 0.80)。在EA中,安慰剂组的阿片类药物阳性UDS发生率也高于BUP-XR组(对数比值比= 1.97,95% CI = 1.14,2.79),但基因型与治疗相互作用显著(χ 2(1)= 4.33,P = 0.04)。  我们发现rs678849对EA中OUD的丁丙诺啡治疗反应有调节作用,但对AA无调节作用。这些发现需要在对接受BUP-XR治疗的AA和EA OUD患者进行的充分、前瞻性研究中进行复制,并根据rs678849基因型进行分层。
Buprenorphine treatment is not equally effective in all patients with opioid use disorder (OUD). Two retrospective studies showed that, among African Americans (AAs), rs678849, a polymorphism in the delta-opioid receptor gene, moderated the therapeutic effect of sublingual buprenorphine. We examined rs678849 as a moderator of the response to an extended-release subcutaneous buprenorphine formulation (BUP-XR) in a 24-week OUD treatment study of 127 AAs and 327 European Americans (EAs). Participants were randomly assigned to receive: (1) BUP-XR as 2 monthly injections of 300 mg followed by either 300 mg monthly or 100 mg monthly for 4 months, or (2) monthly volume-matched placebo injections. Generalized estimating equations logistic regression analyses tested, per population group, the main and interaction effects of treatment (BUP-XR vs placebo) and genotype group (rs678849*CC vs CT/TT) on weekly urine drug screens (UDS). Among AAs, the placebo group had higher rates of opioid-positive UDS than the BUP-XR group (log odds ratio = 1.67, 95% CI = 0.36, 2.98), but no genotype by treatment effect (P = .80). Among EAs, the placebo group also showed higher rates of opioid-positive UDS than the BUP-XR group (log odds ratio = 1.97, 95% CI = 1.14, 2.79) but a significant genotype by treatment interaction (χ 2(1) = 4.33, P = .04). We found a moderating effect of rs678849 on the response to buprenorphine treatment of OUD in EAs, but not AAs. These findings require replication in well-powered, prospective studies of both AA and EA OUD patients treated with BUP-XR and stratified on rs678849 genotype.
