Abstract

BACKGROUND & AIMS: Direct-acting antiviral therapies (DAA) are an important tool for hepatitis C virus (HCV) elimination. However, reinfection among people who inject drugs (PWID) may hamper elimination targets. Therefore, we estimated HCV reinfection rates among DAA-treated individuals, including PWID.

METHODS

We analyzed data from the British Columbia Hepatitis Testers Cohort which included ∼1.7 million individuals screened for HCV in British Columbia, Canada. We followed HCV-infected individuals treated with DAAs who achieved a sustained virologic response (SVR) and had ≥1 subsequent HCV RNA measurement to April 22nd, 2018. Reinfection was defined as a positive RNA measurement after SVR. PWID were identified using a validated algorithm and classified based on recent (<3 years) or former (≥3 years before SVR) use. Crude reinfection rates per 100 person-years (PYs) were calculated. Poisson regression was used to model adjusted incidence rate ratios (IRRs) and 95% CIs.

RESULTS

Of 4,114 individuals who met the inclusion criteria, most were male (n = 2,692, 65%), born before 1965 (n = 3,411, 83%) and were either recent (n = 875, 21%) or former PWID (n = 1,793, 44%). Opioid-agonist therapy (OAT) was received by 19% of PWID. We identified 40 reinfections during 2,767 PYs. Reinfection rates were higher among recent (3.1/100 PYs; IRR 6.7; 95% CI 1.9-23.5) and former PWID (1.4/100 PYs; IRR 3.7; 95% CI 1.1-12.9) than non-PWID (0.3/100 PYs). Among recent PWID, reinfection rates were higher among individuals born after 1975 (10.2/100 PYs) and those co-infected with HIV (5.7/100 PYs). Only one PWID receiving daily OAT developed reinfection.

CONCLUSIONS

Population-level reinfection rates remain elevated after DAA therapy among PWID because of ongoing exposure risk. Engagement of PWID in harm-reduction and support services is needed to prevent reinfections.

LAY SUMMARY

Direct-acting antivirals are an effective tool for the treatment of hepatitis C virus, enabling the elimination of the virus. However, some patients who have been successfully treated with direct-acting antivirals are at risk of reinfection. Our findings showed that the risk of reinfection was highest among people with recent injection drug use. Among people who inject drugs, daily use of opioid-agonist therapy was associated with a lower risk of reinfection.

摘要

背景与目的

直接作用抗病毒药物(DAA)是消除丙型肝炎病毒(HCV)的重要工具。然而,在注射毒品者(PWID)中再次感染可能会阻碍消除目标的实现。因此,我们评估了包括 PWID 在内的 DAA 治疗个体中的 HCV 再感染率。

方法

我们分析了不列颠哥伦比亚省肝炎检测者队列的资料,该队列包括加拿大不列颠哥伦比亚省约 170 万人接受 HCV 筛查。我们随访了接受 DAA 治疗并获得持续病毒学应答(SVR)且随后至少有 1 次 HCV RNA 测量的 HCV 感染个体,随访至 2018 年 4 月 22 日。SVR 后阳性 RNA 测量定义为再感染。使用经过验证的算法确定 PWID,并根据近期(<3 年)或以前(SVR 前≥3 年)使用情况进行分类。计算每 100 人年(PY)的粗再感染率。使用泊松回归对调整后的发病率比(IRR)和 95%置信区间(CI)进行建模。

结果

在符合纳入标准的 4114 名个体中,大多数为男性(n=2692,65%),出生于 1965 年以前(n=3411,83%),近期(n=875,21%)或以前(n=1793,44%)为 PWID。19%的 PWID 接受了阿片类激动剂治疗。我们在 2767 PY 中发现了 40 例再感染。近期(3.1/100 PYs;IRR 6.7;95%CI 1.9-23.5)和以前(1.4/100 PYs;IRR 3.7;95%CI 1.1-12.9)PWID 的再感染率高于非 PWID(0.3/100 PYs)。在近期 PWID 中,出生于 1975 年以后的个体(10.2/100 PYs)和合并感染 HIV 的个体(5.7/100 PYs)的再感染率更高。只有 1 名接受每日阿片类激动剂治疗的 PWID 发生了再感染。

结论

由于持续存在暴露风险,DAA 治疗后 PWID 的人群水平再感染率仍然很高。需要使 PWID 参与减少伤害和支持服务,以预防再感染。
