Abstract
The opioid epidemic has fueled infectious disease epidemics. We determined the impact of medications for opioid use disorder (MOUD) on treatment outcomes of opioid use disorder (OUD)-associated infectious diseases: antiretroviral therapy (ART) adherence, human immunodeficiency virus (HIV) viral suppression, hepatitis C virus (HCV) sustained virologic response, HCV reinfection, new hepatitis B virus infections, and infectious endocarditis-related outcomes. Manuscripts reporting on these infectious disease outcomes in adults with OUD receiving MOUD compared with those with OUD "not" receiving MOUD were included. Initial search yielded 8169 papers; 9 were included in the final review. The meta-analysis revealed that MOUD was associated with greater ART adherence (odds ratio [OR] = 1.55; 95% confidence interval [CI] = 1.12-2.15) and HIV viral suppression (OR = 2.19; 95% CI = 1.88-2.56). One study suggested a positive association between MOUD and HCV sustained virologic response. There is significant support for integrating MOUD with HIV treatment to improve viral suppression among persons with HIV (PWH) and OUD. Treatment of OUD among PWH should be a priority to combat the opioid and HIV epidemics.

Abstract
BACKGROUND Hepatitis C virus (HCV) remains a major contributor to morbidity and mortality worldwide. Since 2009, Kentucky has led the United States in cases of acute HCV, driven largely by injection drug use in rural areas. Improved treatment regimens hold promise of mitigating the impact and transmission of HCV, but numerous barriers obstruct people who inject drugs (PWID) from receiving care, particularly in medically underserved settings. METHODS 503 rural people who use drugs were recruited using respondent-driven sampling and received HCV screening and post-test counseling. Presence of HCV antibodies was assessed using enzyme immunoassay of dried blood samples. Sociodemographic and behavioral data were collected using computer-based questionnaires. Predictors of contacting a healthcare provider for follow-up following HCV-positive serotest and counseling were determined using discrete-time survival analysis. RESULTS 150 (59%) of 254 participants reported contacting a healthcare provider within 18 months of positive serotest and counseling; the highest probability occurred within six months of serotesting. 35 participants (14%) reported they were seeking treatment, and 21 (8%) reported receiving treatment. In multivariate time-dependent modeling, health insurance, internet access, prior substance use treatment, meeting DSM-IV criteria for generalized anxiety disorder, and recent marijuana use increased the odds of making contact for follow-up. Participants meeting criteria for major depressive disorder and reporting prior methadone use, whether legal or illegal, were less likely to contact a provider. CONCLUSION While only 8% received treatment after HCV-positive screening, contacting a healthcare provider was frequent in this sample of rural PWID, suggesting that the major barriers to care are likely further downstream. These findings offer insight into the determinants of engaging the cascade of medical treatment for HCV and ultimately, treatment-as-prevention. Further study and increased resources to support integrated interventions with effectiveness in other settings are recommended to mitigate the impact of HCV in this resource-deprived setting.

Abstract
Inadequate hepatitis C virus (HCV) assessment and treatment among people who inject drugs (PWID) is a result of patient, provider and health system level barriers. Low HCV treatment rates continue even though guidelines have been revised to consider HCV treatment among PWID on a case-by-case basis. If accessibility to HCV treatment were increased, especially to PWID this would greatly decrease the pool of communicable disease. In order to successfully control and prevent HCV infection PWID must be actively engaged in the treatment process. Physicians’ attitudes towards HCV treatment can be represented in studies as views that are directly perceived by the physician or indirectly as perceived by the patient who is under the care of the physician. The current review focuses on examining both the indirect and direct views of physician’s attitudes in treating HCV-infected PWID and examines how this influences and impacts provision of HCV treatment. A review of the literature suggests that physician’s have varied attitudes towards their patients who use recreational drugs and who are HCV positive. Moreover it is the negative associations between HCV and drug use that can impact HCV treatment accessibility and affect the number of people who can actively begin treatment.

Abstract
People who inject drugs (PWID) are central to the hepatitis C virus (HCV) epidemic. Opioid substitution treatment (OST) of opioid dependence has the potential to play a significant role in the public health response to HCV by serving as an HCV prevention intervention, by treating non-injection opioid dependent people who might otherwise transition to non-sterile drug injection, and by serving as a platform to engage HCV infected PWID in the HCV care continuum and link them to HCV treatment. This paper examines programmatic, structural and policy considerations for using OST as a platform to improve the HCV prevention and care continuum in 3 countries-the United States, Estonia and Viet Nam. In each country a range of interconnected factors affects the use OST as a component of HCV control. These factors include (1) that OST is not yet provided on the scale needed to adequately address illicit opioid dependence, (2) inconsistent use of OST as a platform for HCV services, (3) high costs of HCV treatment and health insurance policies that affect access to both OST and HCV treatment, and (4) the stigmatization of drug use. We see the following as important for controlling HCV transmission among PWID: (1) maintaining current HIV prevention efforts, (2) expanding efforts to reduce the stigmatization of drug use, (3) expanding use of OST as part of a coordinated public health approach to opioid dependence, HIV prevention, and HCV control efforts, (4) reductions in HCV treatment costs and expanded health system coverage to allow population level HCV treatment as prevention and OST as needed. The global expansion of OST and use of OST as a platform for HCV services should be feasible next steps in the public health response to the HCV epidemic, and is likely to be critical to efforts to eliminate or eradicate HCV.

Abstract
In high income countries, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). In many low and middle income countries large HCV epidemics have also emerged among PWID populations. The burden of HCV-related liver disease among PWID is increasing, but treatment uptake remains extremely low. There are a number of barriers to care which should be considered and systematically addressed, but should not exclude PWID from HCV treatment. The rapid development of interferon-free direct-acting antiviral (DAA) therapy for HCV infection has brought considerable optimism to the HCV sector, with the realistic hope that therapeutic intervention will soon provide near optimal efficacy with well-tolerated, short duration, all oral regimens. Further, it has been clearly demonstrated that HCV treatment is safe and effective across a broad range of multidisciplinary healthcare settings. Given the burden of HCV-related disease among PWID, strategies to enhance HCV assessment and treatment in this group are urgently needed. These recommendations demonstrate that treatment among PWID is feasible and provide a framework for HCV assessment and care. Further research is needed to evaluate strategies to enhance testing, linkage to care, treatment, adherence, viral cure, and prevent HCV reinfection among PWID, particularly as new interferon-free DAA treatments for HCV infection become available.

Abstract
Patients with chronic HCV have predictable overlapping comorbidities that reduce access to care. The Affordable Care Act (ACA) presents an opportunity to focus on the benefits of the medical home model for integrated chronic disease management. New, highly effective HCV treatment regimens in combination with the medical home model could reduce disease prevalence. We sought to address challenges posed by comorbidities in patients with chronic HCV infection and limitations within our health care system, and recommend solutions to maximize the public benefit from ACA and the new drug regimen.

Abstract
An increase in liver-related causes of death in HIV-positive patients who are coinfected with the hepatitis C virus (HCV) has been acknowledged over the last few years, particularly since the mid 1990s, when the natural history of HIV infection started to improve with the use of highly active antiretroviral therapy (HAART). Chronic hepatitis C is very common among HIV-infected patients who were infected through intravenous drugs use or contaminated blood products (e.g., hemophiliacs). The bidirectional interferences between HIV and HCV modify the natural history of both infections. Moreover, interactions between anti-HIV and anti-HCV drugs are of concern, and a lower response to anti-HCV therapy limits its benefit in HIV-coinfected patients. Although a slower HCV RNA decay is seen in coinfected patients after standard therapy is initiated with pegylated interferon plus ribavirin, the stopping rule at week 12 that is recommended for HCV-monoinfected individuals seems to be equally valid in HIV-positive patients. This finding is of great value, because it allows treatment to be offered in the absence of contraindication (e.g., low CD4 count, alcohol abuse, etc.) but discontinued as early as 12 weeks when no chances of cure are predicted, which saves costs and deleterious side effects. HAART therapy seems to temper somehow the negative impact exerted by HIV infection over HCV-related liver fibrosis. Liver transplantation is currently the best option for HIV-infected patients with end-stage liver disease. However, the management of patients on the waiting list and after transplantation carries significant new challenges. New anti-HCV drugs are urgently needed and new strategies with the currently available drugs need to be assessed to reduce the negative impact of hepatitis C in HIV-coinfected individuals.

Abstract
AIM Peer support services have been shown to be beneficial in increasing uptake and adherence to treatment in other areas but few examples of these services exist in hepatitis C (HCV) care. This study examined the performance of two community-controlled peer support services operating within a larger study aimed at increasing access to HCV care and treatment for opiate substitution treatment (OST) clients, ETHOS. METHODS Semi-structured interviews were conducted in two clinics with three groups of participants: clients (n=31), staff (n=8) and peer workers (n=3) and examined the operation of the service in relation to process, outputs and impacts. RESULTS There was a very strong positive response to the peer worker services reported by staff and clients who had and had not interacted with a peer worker. A number of changes were reported that were not explicit goals of the service including providing access to additional services for clients and staff, peer workers acting as mediators between clients and staff and a less tangible notion of a changing "feel" of the clinic to a more positive and client-friendly social and physical space. Explicit goals of the service were also reported in peer workers supporting clients to consider and prepare for treatment (via blood tests and other assessments) as well as provide information and support about treatment. CONCLUSIONS The peer support service was acceptable to clients and clinic staff. All groups of participants noted that the service met its goals of engaging clients, building trusting relationships and providing instrumental support for clients to access HCV treatment. Peer workers may also contribute to more effective deployment of health resources by preparing clients for clinical engagement with HCV health workers.

Abstract
In this decade, an increase is expected in end-stage liver disease and hepatocellular carcinoma, most commonly caused by hepatitis C virus (HCV) infection. Although people who inject drugs (PWID) are the major source for HCV infection, they were excluded from antiviral treatments until recently. Nowadays there is incontrovertible evidence in favor of treating these patients, and substitution therapy and active substance use are no longer contraindications for antiviral treatment. The viral clearance in PWID after HCV antiviral treatment with interferon or pegylated interferon combined with ribavirin is comparable to the viral clearance in non-substance users. Furthermore, multidisciplinary approaches to delivering treatment to PWID are advised, and their treatment should be considered on an individualized basis. To prevent the spread of HCV in the PWID community, recent active PWID are eligible for treatment in combination with needle exchange programs and substitution therapy. As the rate of HCV reinfection is low after HCV antiviral treatment, there is no need to withhold HCV treatment due to concerns about reinfection alone. Despite the advances in treatment efficacies and data supporting their success, HCV assessment of PWID and initiation of antiviral treatment remains low. However, the proportion of PWID assessed and treated for HCV is increasing, which can be further enhanced by understanding the barriers to and facilitators of HCV care. Removing stigmatization and implementing peer support and group treatment strategies, in conjunction with greater involvement by nurse educators/practitioners, will promote greater treatment seeking and adherence by PWID. Moreover, screening can be facilitated by noninvasive methods for detecting HCV antibodies and assessing liver fibrosis stages. Recently, HCV clearance has become a major endpoint in the war against drugs for the Global Commission on Drug Policy. This review highlights the most recent evidence concerning HCV infection and treatment strategies in PWID.

Abstract
This review synthesized the literature for barriers to HCV antiviral treatment in persons with HIV/HCV co-infection. Searches of PubMed, Embase, CINAHL, and Web of Science were conducted to identify relevant articles. Articles were excluded based on the following criteria: study conducted outside of the United States, not original research, pediatric study population, experimental study design, non-HIV or non-HCV study population, and article published in a language other than English. Sixteen studies met criteria and varied widely in terms of study setting and design. Hepatic decompensation was the most commonly documented absolute/nonmodifiable medical barrier. Substance use was widely reported as a relative/modifiable medical barrier. Patient-level barriers included nonadherence to medical care, refusal of therapy, and social circumstances. Provider-level barriers included provider inexperience with antiviral treatment and/or reluctance of providers to refer patients for treatment. There are many ongoing challenges that are unique to managing this patient population effectively. Documenting and evaluating these obstacles are critical steps to managing and caring for these individuals in the future. In order to improve uptake of HCV therapy in persons with HIV/HCV co-infection, it is essential that barriers, both new and ongoing, are addressed, otherwise, treatment is of little benefit.

Abstract
In the developed world, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). The burden of HCV-related liver disease in this group is increasing, but treatment uptake among PWID remains low. Among PWID, there are a number of barriers to care that should be considered and systematically addressed, but these barriers should not exclude PWID from HCV treatment. Furthermore, it has been clearly demonstrated that HCV treatment is safe and effective across a broad range of multidisciplinary healthcare settings. Given the burden of HCV-related disease among PWID, strategies to enhance HCV assessment and treatment in this group are urgently needed. These recommendations demonstrate that treatment among PWID is feasible and provides a framework for HCV assessment, management, and treatment. Further research is needed to evaluate strategies to enhance assessment, adherence, and SVR among PWID, particularly as new treatments for HCV infection become available.

Client and staff experiences of a co-located service for hepatitis C care in opioid substitution treatment settings in New South Wales, Australia. Drug Alcohol Depend 2013; 133:529-34. [PMID: 23932843 DOI: 10.1016/j.drugalcdep.2013.07.023] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Revised: 07/18/2013] [Accepted: 07/18/2013] [Indexed: 01/29/2023]
Abstract
BACKGROUND Internationally, there are ongoing efforts to increase access to hepatitis C (HCV) assessment and treatment to counter a generally low uptake of treatment among people with a history of injecting drug use. The aim of this qualitative study was to examine client and staff attitudes towards and experience of co-location of HCV and opioid substitution treatment (OST) services. METHODS In-depth interviews were conducted with 57 clients and 19 staff from four NSW clinics participating in the Australian ETHOS study. RESULTS Client and staff participants typically welcomed integrated treatment, citing issues of convenience, reduced travel time and costs, persistent cues to engagement and immediacy of access to care. Positive attitudes towards the initiative were expressed even by clients who had not engaged with HCV care. Providing co-located care largely avoided the negative, stigmatising or discriminatory experiences that participants reported encountering in settings less familiar with people who use drugs. A minority of client participants expressed concerns about the lack of privacy and/or confidentiality available in the co-located model, preferring to seek HCV care elsewhere. CONCLUSIONS The co-location of HCV care in OST clinics was welcomed by the large majority of participants in this study. Besides issues of convenience, the appeal of the co-located service centred on the familiarity of existing relationships between clients and staff in the OST setting. While some clients remained distrustful of OST and chose not to take up HCV care in this setting, the co-located treatment model was overwhelmingly successful amongst both client and staff participants.

Abstract
OBJECTIVES Despite high rates of hepatitis C virus (HCV) infection, relatively few current or former injection drug users receive evaluation and treatment for HCV. Here, we demonstrate the feasibility and effectiveness of integrating HCV care and methadone maintenance treatment (MMT). We hypothesized that colocation of these services would result in improved access to and utilization of HCV care. METHODS In this retrospective observational study, all patient charts from a single MMT clinic were reviewed 2 years after HCV care and MMT were integrated. Information obtained included screening for and counseling about HCV infection status, on-site HCV treatment and outcomes, and demographic and substance abuse data. RESULTS Two hundred ninety-one patient charts were reviewed. Two hundred eighty-one (99%) patients were screened for HCV antibody (HCV-Ab), and 188 (65%) were positive. Forty-nine (17%) patients were HIV/HCV coinfected. Ninety-eight percent of the HCV-Ab-positive patients received HCV counseling. Hundred fifty-nine (85%) of the HCV-Ab-positive patients were eligible to receive further evaluation and treatment for HCV on site, and 125 (78%) accepted. Hundred eighteen (94%) patients were tested for chronic HCV, and 83 were determined to have chronic HCV. Twenty-five patients received liver biopsy; low-stage disease was found in 7 patients. Twenty-one patients initiated HCV treatment. Sustained viral response was achieved in 8 patients. Seventeen patients had contraindications to HCV treatment. Further workup was prevented or delayed in 45 patients for various reasons, most commonly due to personal choice (29 patients). CONCLUSIONS This study demonstrates that current and former injection drug users can be engaged successfully in evaluation and treatment of HCV infection when these services are collocated with MMT.

Abstract
OBJECTIVE The objective was to determine the impact of stimulant use on antiviral treatment for chronic hepatitis C patients in an integrated hepatitis clinic. METHODS A retrospective chart review of 449 consecutive patients seen in an integrated hepatitis clinic that included co-located mental health clinicians was performed. Psychiatric measures included drug use questionnaire, Beck Depression Inventory (BDI), Alcohol Use Disorders Identification Test-Consumption questions (AUDIT-C), urine drug screen and antiviral treatment outcomes. Patients with stimulant use were compared to patients with no drug use, other drug users and an unknown drug use group using χ(2) and analysis of variance tests. RESULTS Over 15% of hepatitis C patients presenting to the clinic were using stimulants. Stimulant users had higher BDI and AUDIT-C scores. They were more likely to be followed by a co-located mental health clinician than other groups and were just as likely to initiate and finish antiviral therapy. CONCLUSIONS Recent stimulant use is common in hepatitis C patients presenting to a hepatitis clinic. Stimulant users were more depressed and used alcohol to a greater degree than nonusers but were as likely to start antiviral therapy. An integrated mental health/medical care approach appears to be effective in addressing this difficult-to-treat population.

Abstract
BACKGROUND Illicit drug users have a high prevalence of HCV and represent the majority of newly infected persons in the U.S. Despite the availability of effective HCV treatment, few drug users have been evaluated or treated for HCV. Racial and ethnic minorities have a higher incidence and prevalence of HCV and higher HCV-related mortality. Factors contributing to poor engagement in care are incompletely understood. METHODS Fourteen mixed-gender focus groups of either African American or Latino/a drug users (N = 95) discussed barriers to HCV testing and treatment. Themes were identified through content analysis of focus group discussions. RESULTS Many drug users were tested for HCV in settings where they were receiving care. Outside of these settings, most were unaware of voluntary test sites. After testing HCV positive, drug users reported not receiving clear messages regarding the meaning of a positive HCV test, the impact of HCV infection, or appropriate next steps including HCV clinical evaluations. Many drug users perceived treatment as unimportant because they lacked symptoms, healthcare providers minimized the severity of the diagnosis, or providers did not recommend treatment. Mistrust of the motivations of healthcare providers was cited as a barrier to pursuing treatment. Social networks or social interactions were a source of HCV-related information and were influential in shaping drug users perceptions of treatment and its utility. CONCLUSION Drug users perceived a paucity of settings for self-initiated HCV testing and poor provider-patient communication at test sites and during medical encounters. Notably, drug users reported having an unclear understanding about the meaning of a positive HCV test, the health implications of HCV infection, the importance of clinical evaluations and monitoring, and of treatment options for HCV. Efforts to improve the delivery of clinical messages about HCV infection for drug users at test settings and clinical encounters are needed.

Abstract
Most individuals infected with the hepatitis C have not received antiviral treatment, with mental health and substance abuse problems being the primary barrier. Interventions have been developed to address these barriers among HCV patients considered "high-risk" for antiviral treatment. We present the design and methods of a prospective, randomized controlled multisite trial being conducted in the Veterans Affairs Healthcare System. The study employed a parallel design and the three study sites randomized a total of 364 VA patients with HCV to either Integrated Care (IC) or Usual Care (UC). The IC intervention consisted of a mental health provider (MHP) performing a) brief interventions to address risk factors; b) collaborative consultation with the HCV treatment clinicians; and c) case management prior to and during antiviral treatment. Clinical outcomes were abstracted from patient medical records and self-report questionnaires were completed at baseline, 4-months, 16-months, and 22-months after enrollment. The primary outcome of the study was sustained viral response (SVR). Secondary clinical outcomes were HCV treatment initiation and completion rates. Other secondary outcomes included substance use, depression, PTSD symptoms, quality of life, healthcare satisfaction, and healthcare utilization. The Integrated Care intervention has the potential to transform HCV antiviral treatment by increasing the number of HCV-infected individuals that can be successfully treated.

Abstract
Background Evidence documents successful hepatitis C virus (HCV) treatment outcomes for people who inject drugs (PWID) and interest in HCV treatment among this population. Maximising HCV treatment for PWID can be an effective HCV preventative measure. Yet HCV treatment among PWID remains suboptimal. This review seeks to map social factors mediating HCV treatment access. Method We undertook a review of the social science and public health literature pertaining to HCV treatment for PWID, with a focus on barriers to treatment access, uptake and completion. Medline and Scopus databases were searched, supplemented by manual and grey literature searches. A two step search was taken, with the first step pertaining to literature on HCV treatment for PWID and the second focusing on social structural factors. In total, 596 references were screened, with 165 articles and reports selected to inform the review. Results Clinical and individual level barriers to HCV treatment among PWID are well evidenced. These include patient and provider concerns regarding co-morbidities, adherence, and side effect management. Social factors affecting treatment access are less well evidenced. In attempting to map these, key barriers fall into the following domains: social stigma, housing, criminalisation, health care systems, and gender. Key facilitating factors to treatment access include: combination intervention approaches encompassing social as well as biomedical interventions, low threshold access to opiate substitution therapy, and integrated delivery of multidisciplinary care. Conclusion Combination intervention approaches need to encompass social interventions in relation to housing, stigma reduction and systemic changes in policy and health care delivery. Future research needs to better delineate social factors affecting treatment access.

Abstract
Mental health problems frequently occur in chronic infection with the hepatitis C virus (HCV) and during antiviral treatment with pegylated interferon-alpha (PegIFNα) and ribavirin. Depression is one of the most important complications during antiviral treatment of chronic hepatitis C infection. However, an increased prevalence of depression, fatigue, and cognitive disturbances has also been reported in untreated HCV-positive patients. Patients with psychiatric disorders or drug addiction also have an increased risk of HCV infection. Furthermore, because of possible drug-drug interactions, new antivirals administered together with PegIFNα and ribavirin may complicate psychiatric side effect management, even if no specific psychiatric adverse events are known so far for these new drugs. The European liver patient's organization (ELPA) organised a European expert conference to review the literature and develop expert recommendations for the management of mental health problems in HCV infected patients. This paper results from the output of the 2011 EASL meeting and subsequent dialogue with patient groups and relevant experts in Europe. It summarises the current knowledge of HCV infection and the brain; prevalence, course, and neurobiology of IFN-α associated psychiatric side effects; possible risk factors for IFN-α associated depression and suicide attempts; psychiatric management of HCV infected patients before and during antiviral treatment; prevention of IFN- α associated psychiatric side effects; and psychiatric aspects of the new antivirals. The summarised current knowledge about mental health changes before and during antiviral treatment should improve interdisciplinary management of HCV infected patients.

Abstract
Co-infection with either HIV or HBV in chronic hepatitis C patients is common, since all these viruses share transmission routes and geographical distribution. Interaction between these viruses generally amplifies liver damage, increasing the risk of developing end-stage liver disease and hepatocellular carcinoma. HIV-HCV co-infection is associated with poorer response to antiviral therapy. New antivirals against HCV are eagerly awaited for this population. HBV-HCV dual infections are less common. The principles guiding indication of therapy in monoinfected patients should be followed considering which virus replicates in persons with serological markers of dual HBV-HCV infection. Although there is growing evidence supporting the use of direct acting antivirals (DAA) in dually infected patients with active HCV replication, prospective trials should be conducted to demonstrate their benefit, assessing carefully the rate and clinical consequences of HBV rebounds.

Abstract
Despite low uptake of hepatitis C virus (HCV) treatment among HIV co-infected patients, few studies have examined the factors that contribute to provider decisions to recommend treatment. Surveys of 173 co-infected patients and their primary care providers, as well as patient chart data, were collected at 3 HIV clinics in Los Angeles; 73% of the patients had any history of being recommended HCV treatment. Multivariate predictors of being offered treatment included being Caucasian, greater HCV knowledge, receiving depression treatment if depressed, and one's provider having a lower weekly patient load and more years working at the study site. These findings suggest that provider decisions to recommend HCV treatment are influenced by patient factors including race and psychosocial treatment readiness, as well as characteristics of their own practice and treatment philosophy. With changes to HCV treatment soon to emerge, further evaluation of factors influencing treatment decisions is needed to improve HCV treatment uptake.

Abstract
PURPOSE OF REVIEW Despite a high burden of hepatitis C virus (HCV) and HIV infection among IDUs and the advent of effective therapies, assessment and treatment remain limited. The current review focuses on the management of HCV and HIV among IDUs, focusing particularly on recent strategies to enhance assessment, uptake and response to HCV and HIV treatment. RECENT FINDINGS There are compelling data demonstrating that with the appropriate programs, treatment for HIV and HCV among IDUs is successful. However, assessment and treatment for HCV and HIV lags far behind the numbers of IDUs who could benefit from therapy, related to systems, provider and patient-related barriers to care. Strategies for enhancing assessment and treatment for HCV and HIV have been developed, including novel models integrating HCV/HIV care within existing community-based and drug and alcohol clinics, innovative methods for education delivery (including peer-support models) and directly observed therapy. SUMMARY As we move forward, research must move beyond demonstrating that HCV and HIV infections can be successfully treated among IDUs. There is clear evidence that this is both feasible and effective. Novel strategies to enhance assessment, uptake and response to treatment should be evaluated among IDUs to elucidate mechanisms to enhance care for this underserved population.

Abstract
BACKGROUND Hepatitis C virus (HCV) is a prevalent chronic blood-borne infection among opioid-dependent patients on methadone maintenance treatment (MMT). Despite case reports and case-control studies, a randomized controlled trial (RCT) examining HCV treatment adherence in methadone-maintained patients is lacking and was the impetus for this ongoing RCT examining modified directly administered therapy for HCV treatment integrated within a MMT. METHODS Subjects were randomized 1:1 to receive HCV treatment as modified directly observed therapy (mDOT) into the MMT program or at a liver specialty clinic as self-administered therapy (SAT). Randomization was stratified based on HIV status and HCV genotype. RESULTS Twenty-one subjects to date have enrolled in this pilot study. The mDOT subjects have had greater success in starting treatment and 10 of the 12 mDOT subjects achieved early virologic response (EVR) at week 12 and 6 of those 10 achieved sustained virologic response (SVR). Of the nine SAT subjects, only three achieved EVR at week 12 and only one achieved SVR despite not completing the treatment. CONCLUSIONS Hepatitis C treatment can be successfully integrated into a methadone maintenance clinic, and mDOT can be implemented with a methadone clinic's existing nursing and medical staff. Patients struggling with concurrent substance use and mental illness comorbidity may be successfully addressed in such settings and facilitate access to and completion of treatment through the utilization of on-site clinical services for HCV treatment and adherence support with mDOT. The exact importance of site of services and adherence support remains a significant area for future investigation.

Abstract
The hepatitis C virus (HCV) epidemic is a significant public health challenge in Australia. Current initiatives to expand access to HCV treatment focus on opiate substitution therapy (OST) settings where the prevalence of hepatitis C among clients is high. In Australia, the provision of OST for many clients is via large clinics, with an estimated median of 150 clients per service. Conceptually informed by the work of Michel Foucault, our analysis of the proposed integrated treatment model focuses on the critical but overlooked question of organisational culture and power operating within OST. We argue that the specific context of OST not merely reflects but actively participates in the political economy of social exclusion via which the socio-spatial segregation and stigmatisation of the service user as 'drug user' is enacted. This paper analyses data collected from two samples during 2008/9: OST clients living in New South Wales, Australia and a range of OST health professionals working in Australian settings. In total, 27 interviews were conducted with current OST clients; 19 by phone and 8 face-to-face. One focus group and 16 telephone interviews were conducted with OST health professionals. Our analysis of key themes emerging from the interview data suggests that the successful introduction of HCV treatment within the OST clinic is not a given. We are concerned that particular areas of tension, if not explicit contradiction, have been overlooked in current research and debates informing the proposed combination treatment model. We question the appropriateness of co-locating a notoriously arduous, exacting treatment (HCV) within the highly surveillant and regulatory environment of OST. While applauding the intention to improve access to HCV care and treatment for people who inject drugs we caution against a treatment model that risks further entrenching (socio-spatial) stigmatisation amongst those already experiencing significant marginalisation.

Abstract
We set out to describe the prevalence and severity of psychiatric and substance use disorders (SUDs) in methadone maintenance treatment (MMT) patients with chronic hepatitis C virus (HCV) infection and to measure the impact on HCV-treatment eligibility. Psychiatric disorders, SUDs, and HCV-treatment eligibility were assessed in 111 MMT patients prior to a controlled trial of HCV treatment. Lifetime and current diagnosis rates, respectively, were: any non-SUD Axis I disorder: 82% and 57%, any mood disorder: 67% and 35%, any anxiety disorder: 63% and 22%, any psychotic disorder: 11% and 9%. Antisocial personality disorder was present in 40%. A total of 56% met criteria for current SUDs. A total of 66% received psychiatric medications prior to HCV treatment; over half were receiving antidepressants. Despite psychiatric and substance use comorbidity, only 15% of patients were ineligible for HCV treatment: 10% due to failure to complete the evaluation, and 5% due to psychiatric severity. Substance use did not lead to ineligibility in any participant. Multiple logistic regression showed the Beck Depression Inventory contributed significantly to predicting HCV treatment eligibility. Most MMT patients were eligible [corrected] for HCV treatment despite current SUD and non-SUD diagnoses. Depression severity may be a more significant predictor of HCV treatment eligibility than is substance use.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a global health problem. In Western countries, illicit drug users (IDUs) constitute the largest proportion of HCV patients. International guidelines no longer regard ongoing illicit drug use as a contraindication to antiviral therapy for chronic hepatitis C (CHC). Nonetheless, in clinical practice, few IDUs have access to HCV treatment, likely because many physicians believe these patients will have poor adherence or a lack of treatment efficacy. OBJECTIVE The aim of this study was to assess effectiveness and tolerability of combination treatment with ribavirin plus recombinant or pegylated interferon-α in the treatment of CHC in IDUs. METHODS MEDLINE, EMBASE, and the Cochrane Library were searched for relevant studies published in English between 2000 and December 2008. The following terms were searched: chronic hepatitis C, interferons, antiviral agents, methadone, and substance-related disorders. Full-text articles and abstracts were searched using predefined criteria. A manual search of abstracts from 8 international meetings of hepatologists was also conducted. Only prospective studies with a sample size >15 and a homogeneous treatment schedule were included. Articles were extracted independently by 2 of the authors using an electronic standardized form including study quality indicators. RESULTS Sixteen prospective studies were included, and data from a cohort of 953 IDUs were analyzed. The estimated overall sustained virologic response (SVR) and dropout (DO) rates in IDUs were 52% (95% CI, 44%-60%) and 26% (18%-35%, 95% CI), respectively. The rate of psychiatric severe adverse events (SAEs) that led to treatment discontinuation was 2% (95% CI, 1%-3%). These prevalences were not significantly different from those reported in registration trials of treatment of CHC that excluded IDUs from the study population (SVR, 50% [95% CI, 39%-61%]; DO, 26% [95% CI, 12%-41%]; and psychiatric SAEs, 2% [95% CI, 0%-6%]). By subgroup analysis, active ongoing drug use negatively affected the rate of treatment success (39% [95% CI, 30%-49%] vs 55% [95% CI, 45%-64%]; P = 0.02). CONCLUSION Based on data from 16 prospective clinical studies of CHC treatment in IDUs published in the past 10 years, findings on effectiveness and tolerability are comparable to those in the general population.

Abstract
AIMS To evaluate the efficacy, safety and adherence to hepatitis C (HCV) therapy in patients attending tertiary hepatitis clinics who are receiving opioid replacement therapy. DESIGN A non-randomized, open-label study. Participants were treated with pegylated interferon alpha-2a and weight-based ribavirin for 24 weeks (genotype non-1, n = 31) or 48 weeks (genotype 1, n = 22). SETTING Four tertiary hospital hepatitis clinics in Australia. PARTICIPANTS Fifty-three patients with chronic HCV who were receiving opioid replacement therapy. MEASUREMENTS Patients were monitored for virological response, adverse events and adherence. They were also screened for psychiatric illness prior to and throughout the study utilizing two validated instruments: the Mini International Neuropsychiatric Interview (MINI) and Beck Depression Interview (BDI)-II. FINDINGS The overall sustained virological response (SVR) rate was 57% (71% genotype non-1 versus 36% genotype 1), and was similar in active injectors (63%) and non-injectors (53%). The psychological profile of patients based on validated instruments did not change on therapy. The pattern and frequency of adverse effects were comparable to non-opioid replacement patients. Eighty-five per cent of patients were adherent to therapy by 80/80/80 criteria and only two patients who had an end-of-treatment response relapsed, one of whom was not an active injector. CONCLUSIONS Patients on opioid replacement therapy, even if they continue to inject actively, can achieve comparable sustained virological response rates to other populations with pegylated interferon alpha-2a and ribavirin therapy, suffer no excess rates of adverse effects or psychological complications and have good adherence to therapy.

Abstract
Assessment and treatment for hepatitis C virus (HCV) in the community remains low. We evaluated factors associated with HCV specialist assessment and treatment in a cross-sectional study to evaluate treatment considerations in a sample of 634 participants with self-reported HCV infection in New South Wales, Australia. Participants having received HCV specialist assessment (n = 294, 46%) were more likely to be have been older (vs <35 years; 35-44 OR 1.64, P = 0.117; 45-54 OR 2.00, P = 0.024; ≥55 OR 5.43, P = 0.002), have greater social support (vs low; medium OR 3.07, P = 0.004; high OR 4.31, P < 0.001), HCV-related/attributed symptoms (vs none; 1-10 OR 3.89, P = 0.032; 10-21 OR 5.01, P = 0.010), a diagnosis of cirrhosis (OR 2.40, P = 0.030), have asked for treatment information (OR 1.91, P = 0.020), have greater HCV knowledge (OR 2.49, P = 0.001), have been told by a doctor to go onto treatment (OR 3.00, P < 0.001), and less likely to be receiving opiate substitution therapy (OR 0.10, P < 0.001) and never to have seen a general practitioner (OR 0.24, P < 0.001). Participants having received HCV treatment (n = 154, 24%) were more likely to have greater fibrosis (vs no biopsy; none/minimal OR 3.45, P = 0.001; moderate OR 11.47, P < 0.001; severe, OR 19.51, P < 0.001), greater HCV knowledge (OR 2.57; P = 0.004), know someone who has died from HCV (OR 2.57, P = 0.004), been told by a doctor to go onto treatment (OR 3.49, P < 0.001), were less likely to have been female (OR 0.39, P = 0.002), have recently injected (OR 0.42, P = 0.002) and be receiving opiate substitution therapy (OR 0.22, P < 0.001). These data identify modifiable patient-, provider- and systems-level barriers associated with HCV assessment and treatment in the community that could be addressed by targeted interventions.

Abstract
SUMMARYOver the last 40 years, the dynamics of hepatitis C virus (HCV) infection in drug users has been affected by the illicit drug market, the health environment including the devastating impact of the HIV/AIDS epidemic which erupted in the 1980s, and the diffusion of substitution treatment beginning in 1995. The purpose of this literature review is to present the dynamics of HCV infection in drug users in France over the last 40 years. Two prevalence studies of HCV infection in the general population were conducted by the French Institute for Public Health Surveillance in 1994 and 2004 and were the touchstone data sources for this analysis. Hypotheses constructed from the findings of these two studies were examined in light of results reported by multicentre prevalence and incidence studies in drug-user populations. The incidence of HCV infection in drug users in France reached a peak in the late 1980s or early 1990s after a lengthy period of epidemic expansion. Implementation of a risk reduction policy enabled a very significant reduction in the incidence of HCV infection in drug users over the last 20 years, leading to incidence figures which are now 10–15% of the 1990 estimate.

Abstract
Comorbid medical illness is common in patients with chronic hepatitis C (HCV) infection and in methadone treatment (MMT) patients, yet little is known about the impact of medical illness on HCV treatment eligibility. Medical illness and HCV treatment eligibility were compared in a case-control study of 80 MMT patients entering an HCV treatment trial and 80 matched non-MMT patients entering HCV treatment in a gastroenterology clinic. 91% of MMT and 85% of non-MMT patients had chronic medical conditions. Despite similar medical severity ratings, a significantly higher proportion (77%) of non-MMT patients were eligible for HCV treatment than were MMT patients (56%) (p<.01). Specific comorbid medical and psychiatric illness led to ineligibility in only 18% of MMT and 16% of non-MMT patients. However, failure to complete the medical evaluation process was significantly (p<.001) more likely to cause ineligibility among MMT patients (19%) than non-MMT patients (0%).

Abstract
BACKGROUND As drug abuse and addiction have been shown to decrease adherence to treatment of hepatitis C virus (HCV) or HIV, screening for substance use should be standard clinical practice in those undergoing an evaluation for these diseases. AIMS To assess the effectiveness of the Kreek-McHugh-Schluger-Kellogg (KMSK) scale to quantify substance use and dependence among patients with viral hepatitis. METHODS The KMSK scale, a validated instrument that quantifies lifetime use of alcohol, cocaine, heroin, and tobacco, was distributed to 161 consecutive patients referred to a hepatology clinic at an academic, tertiary-care center over a 1-year period. RESULTS Of the 159 patients who returned the KMSK scale, 62% reported illicit drug use and 30% met defined criteria for lifetime dependence on cocaine or heroin. We found that 15% of our population at some time had been co-dependent on cocaine and heroin. The KMSK scale identified significantly more cocaine, heroin, and alcohol use than that detected through the medical record (chi(2)=7.61, p<0.01, chi(2)=9.66, p<0.002, respectively). Cocaine dependence was significantly higher among HCV/HIV co-infected than among mono-infected patients (chi(2)=5.46, p<0.02). CONCLUSIONS The KMSK scale may be useful to diagnose drug and alcohol use and dependence among patients undergoing evaluation for treatment of viral hepatitis.

Abstract
Barriers to management of HCV in injection drug users are related to patients, health providers, and facilities. In a primary care drug user's addiction centre we studied access to HCV standard of care before and after using an onsite total care concept provided by a multidisciplinary team and noninvasive liver fibrosis evaluation.
A total of 586 patients were seen between 2002 and 2004. The majority, 417 patients, were HCV positive and of these patients 337 were tested positive for HCV RNA. In 2002, patients were sent to the hospital. with the Starting of 2003, patients were offered standard of care HCV management in the center by a team of general practitioners, a consultant hepatologist, psychiatrists, nurses, and a health counsellor. Liver fibrosis was assessed by a non invasive method.
In 2002, 6 patients had liver fibrosis assessment at hospital facilities, 4 patients were assessed with liver biopsy and 2 patients with Fibrotest-Actitest. 2 patients were treated for HCV at hospital. In 2003 and 2004, 224 patients were assessed with Fibrotest-Actitest on site. Of these, 85 were treated for HCV. SVR was achieved in 43%.
We conclude that the combination of an onsite multidisciplinary team with the use of a noninvasive assessment method led to improved management of HCV infection in drug users' primary care facility.

Abstract
Pain management in patients with cirrhosis is a difficult clinical challenge for health care professionals, and few prospective studies have offered an evidence-based approach. In patients with end-stage liver disease, adverse events from analgesics are frequent, potentially fatal, and often avoidable. Severe complications from analgesia in these patients include hepatic encephalopathy, hepatorenal syndrome, and gastrointestinal bleeding, which can result in substantial morbidity and even death. In general, acetaminophen at reduced dosing is a safe option. In patients with cirrhosis, nonsteroidal anti-inflammatory drugs should be avoided to avert renal failure, and opiates should be avoided or used sparingly, with low and infrequent dosing, to prevent encephalopathy. For this review, we searched the available literature using PubMed and MEDLINE with no limits.

Abstract
Hepatitis C virus (HCV) knowledge, attitudes, beliefs, and experiences (KABE) of 64 HCV antibody positive methadone maintenance treatment (MMT) patients were assessed in conjunction with acceptability of an on-site semi-structured HCV education session, HCV RNA diagnostic testing, HCV treatment motivational assessment, and initiation of HCV treatment. The KABE interviews were conducted in 2006 and 2007 in an urban New York State MMT clinic in affiliation with a NIDA-funded HCV research project. The majority had basic knowledge of HCV disease, but poor understanding of HCV testing and treatment. While the majority of participants expressed fear of HCV treatment side effects, 88% accepted HCV RNA testing and 78% expressed willingness to start HCV treatment with the majority of chronically infected choosing to start HCV treatment medications. Study limitations and implications are discussed.

Abstract
OBJECTIVES We evaluated assessment and treatment for hepatitis C virus (HCV) among illicit drug users accepting referral to a weekly HCV peer-support group at a multidisciplinary community health centre. METHODS From March 2005 to 2008, HCV-infected individuals were referred to a weekly peer-support group and assessed for HCV infection. A retrospective chart review of outcomes 3 years after the initiation of the group was conducted (including HCV assessment and treatment). RESULTS Two hundred and four HCV antibody-positive illicit drug users accepted referral to a weekly HCV peer-support group. Assessment for HCV occurred in 53% of patients(n= 109), with 13% (n= 14) having initiated or completed treatment for HCV infection before attending the support group, evaluation ongoing in 10% (n= 11) and treatment deferred/not indicated in 25% (n= 27). The major reasons for HCV treatment deferral included early disease (30%),drug dependence (37%), other medical (11%) or psychiatric comorbidities (4%). Sixty-eight percent of those deferred for reasons other than early liver disease showed multiple reasons for treatment deferral. The first 4 weeks of support group attendance predicted successful HCV assessment (odds ratio: 6.03, 95% confidence interval:3.27-11.12, P < 0.001). Overall, 28% (n= 57) received treatment. Among individuals having completed pegylated-interferon and ribavirin therapy with appropriate follow-up (n =19), the rate of sustained virologic response was 63% (12/19), despite illicit drug use in 53%. CONCLUSION A high proportion of illicit drug users accepting referral to a weekly HCV peer-support group at a multidisciplinary health centre were assessed and treated for HCV infection. Peer support coupled with multidisciplinary care is an effective strategy for engaging illicit drug users in HCV care.

Abstract
Ignorance about Hepatitis-C (HCV) among drug users, treatment staff, and policy makers thwarts treatment uptake and facilitates virus transmission. We assessed knowledge about HCV among methadone patients in Israel, where effective HCV-treatment is provided at low-cost within the national health insurance framework, yet few infected methadone patients are treated. In 2006, 512 patients in two methadone clinics in Israel were interviewed, of whom 53% were HCV-positive. The clinics were purposively selected from the 11 methadone clinics in the country. Respondents exhibited poor knowledge about HCV, particularly about diagnosis and treatment. Lesser-educated respondents were three times more likely to score low on HCV-knowledge compared to those with 12+ years of schooling (AOR = 2.97, 95% CI = 1.5-5.7. HCV-negative patients were also three-times more likely than HCV-positive patients to score low on the HCV-knowledge scale (Adjusted Odds Ratio = 3.0, 95% Confidence Interval = 1.9-4.7). Enhancing HCV-knowledge may help patients avoid becoming infected and infecting others, allay exaggerated fears about hepatitis, and facilitate HCV-treatment initiation among those infected.

Abstract
INTRODUCTION Chronic hepatitis C virus infection (HCV) is the most common infectious disease among intravenous drug users. AIMS To determine and compare compliance rates between two groups of chronic HCV patients from the methadone substitution program of the National Greek Organization Against Drugs treated with either pegylated interferon alpha-2b/ribavirin or with interferon alpha-2b/ribavirin during 48 weeks of therapy and 24 weeks of follow-up. Furthermore, to evaluate the efficacy of each treatment modality. METHODS Forty-five consecutive methadone maintenance (MM) patients (group A, 36 males, nine females) were treated with pegylated interferon alpha-2b (weight-based dosing 1.5 microg/kg/week) and ribavirin 1000-1200 mg/day orally. Sixty-five consecutive MM patients (group B, 52 males, 13 females) were treated with interferon alpha-2b (6 MIU, three times/week) and ribavirin with the doses reported above. During the study, all patients were followed up periodically by hepatologists, internists, and psychiatrists. RESULTS Baseline characteristics were similar between the two groups. Thirty-four out of 45 patients (75.6%) from group A and 31 of 65 patients (47.7%) from group B completed therapy (P =0.006). Thirty-two (71.1%) patients from group A and 27 patients (41.5%) from group B were followed-up until the end of week 72 (P = 0.004). At the end of the follow-up, sustained virologic response was achieved in 23 of 45 (51.1%) patients from group A and 21 of 65 patients (32.3%) from group B (P =0.075). CONCLUSION Pegylated interferon alpha-2b/ribavirin treatment achieved a significantly higher compliance rate than interferon alpha-2b/ribavirin in MM patients with chronic HCV infection. After 24 weeks of follow-up, response rates were similar for patients who were compliant to treatment for both groups.

Abstract
BACKGROUND Despite evidence suggesting that the majority of patients with hepatitis C virus (HCV) have psychiatric and substance use disorders, patients with these comorbidities have historically been excluded from antiviral therapy for HCV. OBJECTIVE The authors compared antiviral completion and sustained virologic response (SVR) rates between hepatitis C (HCV) patients with versus those without preexisting major depressive disorder (MDD). METHOD The authors performed a chart review of HCV patients (30 with MDD and 25 control subjects) who attended an optional HCV education class and signed informed consent allowing collection of clinical data. RESULTS The MDD group had completion and SVR rates similar to those of control subjects. Neuropsychiatric side effects and reasons for discontinuation of treatment were not different between groups. CONCLUSION Patients with MDD can be safely and effectively treated with antiviral therapy.

Abstract
Substance abusers account for the largest number of hepatitis C infected cases in developed countries. We describe a care model for treating current or former substance abusers with antiviral therapy for hepatitis C virus (HCV) infection. The care model involved hepatitis nurses, a psychologist, infectious disease specialist and primary care physicians. Clients met selection criteria including regular attendance at clinic appointments and social stability. Use of alcohol and illicit substances was monitored with urine toxicology screens. The association between substance use, rates of completion of therapy and rates of response were assessed using multivariable regression analyses. A total of 109 clients (75 with genotype 1/4 and 34 with genotype 2/3) received at least one injection with pegylated interferon between November 2002 and January 2006. Treatment completion rates of 61 and 74% were achieved for genotypes 1/4 and 2/3, respectively. Treatment response rates in an intention to treat analysis were 51% for genotypes 1/4 and 68% for genotypes 2/3. A positive urine toxicology screen indicating use of illicit substances 6 months prior to initiating therapy was significantly associated with lower rates of treatment completion but not lower rates of sustained virological response. A positive urine screen indicating use of alcohol prior to therapy was significantly associated with lower rates of completion and lower rates of response. Rates of completion and response are comparable to non-substance abusing populations. Antiviral therapy for HCV infection can be successful within the context of ongoing care for substance abuse for carefully selected patients.

Abstract
OBJECTIVE Neuropsychiatric symptoms are common in patients with chronic hepatitis C (CHC) and can potentially be exacerbated by interferon-alpha treatment. Such symptoms can contribute to problems with treatment adherence, which can significantly compromise epidemiological virus control. This review summarizes current knowledge about the etiology, course, and management of neuropsychiatric symptoms in patients with CHC. METHOD Studies were identified using computerized searches, with further references obtained from the bibliographies of the reviewed articles. RESULTS Psychopathological syndromes that occur during interferon-alpha treatment frequently have atypical features that may complicate their recognition using standard diagnostic criteria. In addition, prospective studies in this area often exclude patients with psychiatric disorders and have methodological disparities that make it difficult to develop guidelines for management of psychiatric side effects induced by interferon-alpha. Despite the high prevalence of chronic hepatitis C virus (HCV) infection in patients with psychiatric and substance use disorders, neuropsychiatric concerns often lead to the exclusion of such patients from interferon-alpha treatment, inappropriately depriving them of the potential benefits of this therapy. CONCLUSION Consultation-liaison psychiatrists should become familiar with the clinical spectrum of presentations associated with HCV infection as well as with related neuropsychiatric symptoms in order to promote the creation of multidisciplinary teams who specialize in the care of patients with HCV infections. More studies are needed to define neuropsychiatric syndromes that can be induced by interferon-alpha and to clarify best assessment and treatment procedures for these syndromes. It is also important to create and evaluate psychoeducational programs for all patients with chronic HCV infections, even those with low risk of complications, in order to promote adherence to therapy and optimize patients' quality of life.

Effects of heroin-assisted treatment on alcohol consumption: findings of the German randomized controlled trial. Alcohol 2009; 43:259-64.

Abstract
Alcohol has been suggested to be a risk factor for opioid-dependent patients in methadone maintenance treatment (MMT). Literature shows that MMT has limited effects on alcohol use. Nevertheless, a decrease in alcohol use was detected in the Swiss heroin-assisted treatment (HAT) study. In this article, we carry out an in-depth analysis of the German HAT trial with the aim of determining whether alcohol use was affected among patients undergoing HAT and MMT. Analysis was carried out using self-reported data on consumption units of alcohol used (CU), Addiction Severity Index composite scores (ASI CSs), and carbohydrate-deficient transferrin (CDT) measures. Results suggest significant reduction of CU and CDT in both groups, yet larger effects in the HAT group. ASI CS significantly decreased in the HAT but not in the MMT group. The greater benefit of HAT in reducing alcohol use may be due to the greater daily frequency of dispensing heroin coupled with a requirement of sobriety at each dosing occasion.

Abstract
According to recent World Health Organization data, approximately 170–200 million people worldwide are infected with hepatitis C virus (HCV). At present, illicit drug users (IDUs) constitute the largest group of individuals infected with HCV in industrial countries. Between 50% and 90% of IDUs are estimated to be positive for anti-HCV antibodies and most of the new infections occur in IDUs. The aim of our review is to focus on tertiary prevention of HCV infection among IDUs. We review strategies to prevent HCV infection and disease progression, attitude to antiviral treatment, access to specific HCV therapy and data of efficacy and safety of antiviral treatment among IDUs.

Abstract
Narcotic analgesics are commonly prescribed drugs in patients with chronic hepatitis C (CHC) infection. In vitro data have shown that morphine enhances hepatitis C virus replication in human hepatic cells, however the effect of narcotics on hepatitis C virus disease progression remains uncertain. The aim of this study was to evaluate the potential effects of narcotic analgesic use on the progression of hepatic fibrosis in patients with CHC infection. We identified CHC patients who had been seen at our institution and had undergone a liver biopsy between 1990 and 2005. Their charts were reviewed for the presence of narcotic analgesic and known risk factors for progression of hepatic fibrosis including male sex, age > or =40, obesity, diabetes, and alcohol abuse. All biopsy were reviewed and fibrosis scores were standardized using the Batts and Ludwig scoring system (stage 0 to 4). A total of 1147 evaluable patients were identified and 171 of these had narcotic analgesic use. In univariate analysis, narcotic analgesic use was associated with the presence of alcohol abuse (P<0.001), obesity (P=0.02), and advanced fibrosis defined as stage 3 to 4 fibrosis (P=0.02), but not with male sex or diabetes. In multivariate logistic regression analysis, obesity [odds ratio (OR) 1.68 (confidence interval (CI), 1.21-2.33)], alcohol abuse [OR 1.45 (CI, 1.04-2.02)], age > or =40 [OR 1.85 (CI, 1.22-2.89)], and diabetes [OR 2.43 (CI, 1.41-4.14)] all independently predicted advanced liver fibrosis but narcotic analgesic use did not [OR 1.71 (CI, 0.99-2.89)]. As the amount of narcotic analgesic use increased from no use, to <3 months use, to > or =3 months use, the frequency of obesity, alcohol abuse, and advanced fibrosis increased accordingly (P=0.005), suggesting that it is difficult to separate these known risk factors from narcotic use as the cause for advanced fibrosis in this population.
