Abstract Background Engaging PWID in HCV treatment and monitoring for reinfection is critical to eliminate HCV and improve health in people who use drugs. However, PWID are often marginalized and can be difficult to engage and retain in care. The collocation of HCV treatment with buprenorphine to treat opioid use disorder (OUD) may improve visit adherence in this population. Methods ANCHOR is a single-center study evaluating treatment of HCV in PWID with chronic HCV, OUD, and IDU. Participants receive sofosbuvir/velpatasvir x12 weeks and are offered collocated buprenorphine. HCV visits occur at weeks 4, 12, 24, 48, 72 and 96. Results At screening, the 100 enrolled patients were predominantly male (76%), black (93%), middle-aged (median 57years), injected opioids daily or more (58%), and were not on OAT (67%). Fifty-five (55%) patients were initiated on collocated buprenorphine at some point after day 0. Being on collocated buprenorphine at the time of HCV visit was associated with increased likelihood of visit attendance at weeks 12 (P = 0.002), 24 (P = 0.01), 48 (P = 0.02), 72 (P = 0.003), and 96 (P = 0.04). For patients who attended study visits, being on collocated buprenorphine was associated with a shorter time between planned visit and actual visit at weeks 12 (P = 0.03), 24 (P = 0.04), and 48 (P = 0.04). When looking at patients not on collocated buprenorphine, being on noncollocated opioid agonist therapy vs. not being on OUD treatment did not impact visit adherence. Conclusion Evidence-based treatment of HCV and OUD are critical to improving health in PWID. The collocation of HCV treatment with office-based buprenorphine may improve adherence to visits and visit timing, especially in long-term follow-up. Infectious disease providers should offer collocated buprenorphine as a tool to improve long-term outcomes and engagement in this high-risk population.

The Impact

Abstract Background People who inject drugs have a high prevalence of hepatitis C virus (HCV) and significant disease associated with drug use; however, HCV treatment often occurs in absence of interventions to address opioid use disorder and drug use–related harms. The impact of concurrent initiation of opioid agonist therapy (OAT) on HCV treatment and drug use outcomes is unknown. Methods In this prospective, open-label, observational trial at a harm reduction organization’s drop-in center in Washington, DC, 100 patients with chronic HCV infection, opioid use disorder, and ongoing injection drug use were treated with sofosbuvir-velpatasvir for 12-weeks and offered buprenorphine initiation. The primary end point was sustained virologic response (SVR), and secondary end points included uptake of and retention in OAT, change in risk behavior, and determinants of SVR. Results Eighty-two patients (82%) achieved SVR, which was not associated with baseline OAT status (P = .33), on-treatment drug use (P >.99), or imperfect daily adherence (P = .35) but was significantly associated with completing 2 or more 28-pill bottles of sofosbuvir-velpatasvir (P < .001) and receiving OAT at week 24 (P = .01). Of 67 patients not already receiving OAT at baseline, 53 (79%) started OAT. At week 24, 68 (68%) patients were receiving OAT. Receipt of OAT was associated with fewer opiate-positive urine drug screens (P = .003), lower human immunodeficiency virus risk-taking behavior scores (P < .001), and lower rates of opioid overdose (P = .04). Conclusions The Novel Model of Hepatitis C Treatment as an Anchor to Prevent HIV, Initiate Opioid Agonist Therapy, and Reduce Risky Behavior study demonstrates high uptake of buprenorphine collocated with HCV treatment, and it shows that concurrent initiation of OAT with HCV treatment can result in high rates of SVR while reducing risks associated with drug use.

Optimal Outcomes

Objective: Studies dating back to 1964 consistently support the effectiveness of methadone as a maintenance treatment for opioid use disorder (OUD), and since 2003, the effectiveness of buprenorphine. Short-term detoxification has not proven to be an effective treatment, as it results in high relapse rates when compared with maintenance treatment with an opioid agonist therapy (OAT). The question about the duration of maintenance treatment for OUD has been debated with recommendations ranging from a minimum of 1 year, 2 years, to indefinitely. Other factors such as misconceptions, regulations, and insurance barriers also have an impact on the duration dilemma of OAT.Design: There were no a priori criteria for article inclusion and this is not a structured literature review. It is a review of articles of convenience from 1964 to 2018.Main outcome measure: This paper aims to address the dilemma of the ideal duration of OAT and to discuss the factors that could affect this decision.Results: Sustained OAT has had significantly better long-term outcomes than short-term detoxification or time limited maintenance. Optimal outcomes are dependent on adequate treatment duration.Conclusions: Addiction is a chronic brain disease and its treatment should be similar to the treatment of other chronic medical and psychiatric diseases. Long-term, sometimes lifetime, continuation of OAT for the treatment of OUD results in optimal outcomes when measuring morbidity and mortality. The accumulated evidence does not support any arbitrary limitation to the duration of OAT.

AbstractIbogaine is a naturally occurring psychedelic medicine with anti-addictive properties. While research on ibogaine is limited, several observational studies have shown ibogaine can mitigate opioid withdrawal, as seen with reductions in clinical and subjective opioid withdrawal scores and reduced drug use severity (Noller, Frampton, & Yazar-Klosinski, 2018; Brown & Alper 2018). Furthermore, the psychoactive experience may help individuals to realign their values, purpose and sense of connection, as seen with post treatment reductions in depression scores (Noller et al., 2018; Mash et al., 2000).Case seriesThis case series describes two cases of individuals accessing ibogaine through private unregulated clinics in the Vancouver area to treat their opioid use disorder.ConclusionsIn case 1, the client achieved total abstinence from all opioids within 5–6 days of starting ibogaine treatment, did not experience any opioid withdrawal symptoms after ibogaine treatment and maintained abstinence from opioids for 3 years. In case 2, the patient took ibogaine/iboga in multiple treatments over a short period of time (<4 months). The patient stopped all non-medical opioids after the first iboga treatment and then used ibogaine to aid with further dose reductions of her opioid agonist therapy (OAT) and has maintained abstinence from opioids for 2 years. Ibogaine offers a unique and novel therapeutic approach to treating opioid use disorder. Further studies are needed to establish the safety, risks and potential role for ibogaine as a mainstream, evidence-based addiction treatment.

IntroductionThe opioid crisis has resulted in increasing rates of death caused by problematic opioid use. Current clinical guidelines recommend that individuals with persons with opioid use disorder (OUD) receive pharmacological (eg, opioid agonist therapy) and psychosocial (eg, cognitive behavioural therapy) therapy; however, the best combination of pharmacologic and psychosocial components is not known. Our objective of the planned study is to conduct a comprehensive systematic review to assess the relative benefits of psychosocial interventions as an adjunct to opioid agonist therapy among persons with OUD.Methods and analysisA comprehensive search for randomised controlled trials published in English or French will be conducted from database inception to March 2018. The search will be conducted in MEDLINE and translated for Embase, PsycINFO and the Cochrane Central Register of Controlled Trials. Two independent reviewers will screen, extract and assess risk of bias of eligible articles. Primary outcomes of interest will be treatment retention and opioid use (based on urinalysis results). Secondary outcomes will include self-reported opioid use, abstinence from illicit drugs, adherence to psychosocial therapy and opioid agonist therapy, risk for sexually transmitted disease, risk for blood borne pathogens, changes in mental health symptoms (eg, depression), measures of craving and changes in patients’ quality of life and relevant adverse events. If sufficient data and adequate homogeneity exists, network meta-analyses (NMA) will be performed.Ethics and disseminationThis will be the first systematic review to incorporate NMA to compare psychosocial treatments used as an adjunct to opioid agonist therapy for OUD. Results of this review will inform clinical management of persons with OUD.Trial registration numberCRD42018090761.

In the wake of North America’s opioid crisis, access to evidence-based treatment for opioid use disorder (OUD) is of critical importance. While buprenorphine/naloxone and methadone are currently indicated as first-line medications for the treatment of OUD, there are a proportion of individuals who do not benefit from these therapies. Recent Canadian guidelines suggest the use of alternate therapies, including slow-release oral morphine or injectable opioid agonist therapy (iOAT) for individuals unsuccessful with either methadone or buprenorphine/naloxone. While the guidelines highlight the need to intensify OUD treatment as disease severity increases, equally important is the consideration for deintensification of treatment (eg, from iOAT to an oral opioid agonist treatment (OAT) option) following successful stabilisation. Literature addressing how best to accomplish this, however, is currently lacking. Accordingly, the case presented here describes a patient that successfully transitions from iOAT to oral buprenorphine/naloxone using a novel induction approach termed microdosing.

Increased Risk

Purpose The prevalence of substance use disorders among incarcerated individuals in Canada is substantially higher than in the general population. Many incarcerated individuals with opioid use disorder remain untreated due to inadequate access to opioid agonist therapy (OAT). A considerable proportion of overdose-related deaths in the province of Ontario are individuals who have recently been released from prison. The purpose of this paper is to highlight that discontinuation of OAT as a disciplinary measure remains an active concern within prisons in Canada and places individuals with opioid use disorder at increased risk of relapse and resultant overdose death. Design/methodology/approach This case report describes an incarcerated client with opioid use disorder who was initially stable on OAT, but was forcibly tapered off OAT as a disciplinary measure and subsequently relapsed to illicit opioid use while in custody. Findings This case calls attention to concerns regarding treatment of opioid use disorder during incarceration, as forcible detoxification from OAT as a disciplinary measure is a highly dangerous practice. The authors discuss concerns regarding diversion and ways in which prison-based OAT programs can be improved to increase their safety and acceptability among correctional staff. Ongoing advocacy is required on the part of health-care workers and policymakers to ensure that individuals are able to appropriately access this life-saving therapy while incarcerated. Originality/value To the best of the authors’ knowledge, this is the first case report to describe forcible tapering of OAT as a disciplinary measure during incarceration. Despite existing evidence emphasizing the significant risk of overdose associated with detoxification from opioids, this case highlights the need for further research into the causes and prevalence of this practice.

Background: Hepatitis C Virus (HCV) treatment in people who inject drugs (PWID) is a key component of elimination models but PWID face substantial barriers to treatment access. Despite data showing treatment outcomes among PWID on medications for opioid use disorder (MOUD) are similar to non-PWID outcomes, few studies examine PWID treatment outcomes with only syringe services support. Objectives: To evaluate the effect of recruitment for HCV treatment with elbasvir/grazoprevir (E/G) in a syringe services program (SSP) as compared to an MOUD program for people with opioid use disorder. Methods: This real-world, multi-site prospective open-label pilot study compares treatment of PWID with aspartate aminotransferase to platelet ratio (APRI) < 0.7 and genotype 1a, 1b, and 4 HCV with E/G, engaged in MOUD (n = 25) or an SSP (n = 25). The MOUD arm was enrolled through a federally qualified community health center and SSP arm through a nearby SSP. Prospective arms were compared to an academic hepatology clinic group (n = 50). Sustained virologic response at 12 weeks (SVR12), medication adherence, and treatment discontinuation were evaluated. Results: In the MOUD vs SSP arms, substance use throughout treatment was found in 36% (9/25) vs 100% (25/25); good adherence (> 90% pills taken) in 100% (25/25) vs 68% (17/25); treatment completion 100% (25/25) vs 64% (16/25); and SVR12 rates were 96% (24/25) vs 60% (15/25). In the community standard comparison group, SVR12 was achieved in 94% (47/50). There were two virologic failures or re-infections in the SSP group; all other non-responders were due to missing SVR12 data. Conclusions: While recruitment and follow-up are challenging in SSPs, preliminary data suggests adherence, treatment completion, and SVR12 are high in PWID treated with E/G engaging in SSP or MOUD. All metrics are comparable to community standards for non-PWID for treatment of HCV with direct-antiviral drugs.

Practical Factors

Methadone is a long-acting full opioid agonist that has a long history in the treatment of opioid use disorder (OUD). It was the first opioid agonist with OUD as an indication for use. Methadone was developed for OUD during a time of prohibition and criminalization of both addiction and the use of opioid agonists for addiction treatment, which resulted in methadone being heavily regulated at multiple levels. Methadone is frequently used in short-term withdrawal management (i.e., detoxification) and in long-term treatment, with the latter producing better treatment outcomes. This chapter explores the basic pharmacology of methadone and the development of methadone for OUD and its accompanying regulations, discusses the place of methadone in treatment for OUD, reviews the effectiveness of methadone treatment, and visits some practical factors related to methadone as part of treatment for OUD.
