THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 72:146-159. [PMID: 31147142 DOI: 10.1016/j.drugpo.2019.05.023] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 05/16/2019] [Accepted: 05/21/2019] [Indexed: 12/29/2022]
Abstract
BACKGROUND Despite the key role that people who inject drugs (PWID) play in the hepatitis C virus (HCV) epidemic, HCV treatment rates among this population have been historically low. Integrated models of HCV and substance use care have the potential to overcome some barriers to access; however, the evidence base is uncertain. This systematic review assesses the impacts of integrated HCV and substance use services on engagement in HCV care among PWID. METHODS We searched five databases up to December 2018 to identify original quantitative studies evaluating the impacts of co-location of HCV and substance use services on engagement in the HCV cascade of care among adult PWID. We conducted a narrative synthesis, categorizing models based on patient entry point (a: HCV facility, b: substance use disorder (SUD) facility, and c: other facilities), and levels of integrated services offered (a: HCV/substance use testing only, b: HCV/substance use treatment, and c: testing/treatment + other services). RESULTS A total of 46 articles corresponding to 44 original studies were included. Almost all studies (n = 42) were conducted in high-income countries and only six studies in the Direct-Acting Antiviral (DAA) era. Twenty-six studies discussed the integration of services at SUD facilities, one at HCV facilities, and seventeen at other facilities. Analysis of included studies indicated that overall integrated care resulted in improved engagement in HCV care (e.g., testing, treatment uptake and cure). However, the quality of evidence was predominantly low to moderate. CONCLUSIONS Available evidence suggests that integration of HCV and substance use services may improve engagement along the continuum of HCV care among PWID. Given limitations in data quality, and very few studies conducted in the DAA era and in low- and middle-income settings, further research is urgently needed to inform strategies to optimize HCV care access and outcomes among PWID globally.

Abstract
The objective of this review is to consider how existing human immunodeficiency virus (HIV) infrastructure may be leveraged to inform and improve hepatitis C virus (HCV) treatment efforts in the HIV-HCV coinfected population. Current gaps in HCV care relevant to the care continuum are reviewed. Successes in HIV treatment are then applied to the HCV treatment model for coinfected patients. Finally, the authors give examples of HCV treatment strategies for coinfected patients in both domestic and international settings.

Abstract
An estimated 70-90% of current methadone users have Hepatitis C (HCV). Current treatments have few side effects and can cure infection in 8-12 weeks, but less than 10% of methadone patients initiate treatment. Engaging this group in treatment is an important strategy to lower both morbidity and mortality from liver disease and eliminate a significant reservoir of HCV in communities. To understand how to address this treatment gap we used commercial marketing techniques called perceptual mapping and vector message modeling to analyze survey data from 100 HCV+ methadone patients from four centers in Philadelphia. Results were used to understand barriers and facilitators to treatment initiation and to devise targeted message strategies to adapt to a mobile health communication intervention. Results indicate that focusing on how treatment can make one feel "in charge", positive interactions with healthcare providers, the positive attributes of the new vs. old HCV treatments, and providing strategies to address tangible barriers to getting treatment, would be important to address in a communication intervention. These marketing methods allow for focusing on specific variables to "move" the group toward a treatment decision, making them an innovative technique to use in developing highly targeted health communication messages.

Abstract
BACKGROUND The frequency in which HIV and AIDS and mental health problems co-exist, and the complex bi-directional relationship between them, highlights the need for effective care models combining services for HIV and mental health. Here, we present a systematic review that synthesizes the literature on interventions and approaches integrating these services. METHODS This review was part of a larger systematic review on integration of services for HIV and non-communicable diseases. Eligible studies included those that described or evaluated an intervention or approach aimed at integrating HIV and mental health care. We searched multiple databases from inception until October 2015, independently screened articles identified for inclusion, conducted data extraction, and assessed evaluative papers for risk of bias. RESULTS Forty-five articles were eligible for this review. We identified three models of integration at the meso and micro levels: single-facility integration, multi-facility integration, and integrated care coordinated by a non-physician case manager. Single-site integration enhances multidisciplinary coordination and reduces access barriers for patients. However, the practicality and cost-effectiveness of providing a full continuum of specialized care on-site for patients with complex needs is arguable. Integration based on a collaborative network of specialized agencies may serve those with multiple co-morbidities but fragmented and poorly coordinated care can pose barriers. Integrated care coordinated by a single case manager can enable continuity of care for patients but requires appropriate training and support for case managers. Involving patients as key actors in facilitating integration within their own treatment plan is a promising approach. CONCLUSION This review identified much diversity in integration models combining HIV and mental health services, which are shown to have potential in yielding positive patient and service delivery outcomes when implemented within appropriate contexts. Our review revealed a lack of research in low- and middle- income countries, and was limited to most studies being descriptive. Overall, studies that seek to evaluate and compare integration models in terms of long-term outcomes and cost-effectiveness are needed, particularly at the health system level and in regions with high HIV and AIDS burden.

Abstract
INTRODUCTION Substance use is an important risk factor for HIV, with both concentrated in certain vulnerable and marginalized populations. Although their management differs, there may be opportunities to integrate services for substance use and HIV. In this paper we systematically review evidence from studies that sought to integrate care for people living with HIV and substance use problems. METHODS Studies were included if they evaluated service integration for substance use and HIV. We searched multiple databases from inception until October 2015. Articles were screened independently by two reviewers and assessed for risk of bias. RESULTS AND DISCUSSION 11,057 records were identified, with 7616 after removal of duplicates. After screening titles and abstracts, 51 met the inclusion criteria. Integration models were categorized by location (HIV, substance use and other facilities), level of integration from mirco (integrated care delivered to individuals) to macro (system level integrations) and degree of integration from least (screening and counselling only) to most (care for HIV, substance use and/or other illnesses at the same facility). Most reported descriptive or cohort studies; in four randomized control trials integrated activities improved patient outcomes. There is potential for integrating services at all facility types, including mobile health services. While services offering screening only can achieve synergies, there are benefits from delivering integrated treatment for HIV and substance use, including ease of referral to other mental health and social services. CONCLUSIONS Our review used a wide range of databases and conference archives to increase representation of papers from low- and middle-income countries. Limitations include the overrepresentation of studies from the United States, and the descriptive nature of the majority of papers. The evidence reviewed shows that greater integration offers important benefits in both patient and service outcomes but further research and outcome reporting is needed to better understand innovative and holistic care models at the complex intersection of substance use and HIV services.

Abstract
BACKGROUND Chronic hepatitis C is common in people who inject drugs (PWID) and this population serves as a reservoir for infection. Treatment levels are low among this group, ranging from 1 to 19%. We explored whether a nurse-initiated community treatment model increased uptake of and adherence to interferon-based therapies. METHODS This was a cluster randomized trial of nurse-initiated versus physician-initiated antiviral therapy with pegylated interferon and ribavirin for hepatitis C virus in community clinics (trial registration: ISRCTN07774040). RESULTS The proportion of participants initiating treatment during follow-up was 10% with nurse-initiated (6/62) and 9% with physician-initiated (6/76) therapy. Adherence was similar in both groups, with only one patient in each arm not adhering to therapy. There were no serious adverse events, but interferon-related side effects were common. Drug and alcohol use did not change during therapy. CONCLUSION Despite easy access to antiviral therapy, uptake of treatment was poor, with no significant difference between the groups. Nurse-led initiation of interferon-based antiviral therapy in PWID did not lead to increased uptake of, response to or adherence with treatment. Further service improvement is unlikely to increase the proportion of PWID undergoing antiviral therapy for hepatitis C virus and early adoption of interferon-free regimens may increase the proportion initiating and completing treatment.

Abstract
While community-based mental health services play an important role in caring for persons with HIV (human immunodeficiency virus) and co-existing mental health disorders, the extent to which their support needs are addressed in this setting is unknown. Accordingly, we examined if HIV infection was associated with unmet support needs among men living with and without HIV receiving community mental health care. This cross-sectional study examined 215 men (135 living with HIV and 80 without HIV) receiving case management services in urban Ontario. Using the Camberwell Assessment of Need, we ascertained the prevalence of support needs in 13 domains grouped into three clusters: Basic needs (accommodation, food, benefits, and money management); self-care/functional needs (daytime activities, self-care, and looking after the home); and health/safety needs (physical, psychological distress, psychotic symptoms, safety to self, and safety to others). We used generalized estimating equations with a logit link to examine the association between HIV and unmet need in each domain. Compared to HIV-negative men, men with HIV were more likely to have mood and concurrent disorders, and intellectual and developmental disabilities. Following multivariable analyses, men with HIV had greater unmet needs related to food (odds ratio + 95% confidence interval: 9.36 (4.03, 21.75), p < 0.001); money (OR: 1.90 (1.04, 3.47), p = 0.036) [basic need domains]; psychological distress (OR: 2.39 (1.68, 3.41), p < 0.001); drug use (OR: 5.10 (2.16, 12.08) p < 0.001); and safety to self (OR: 3.35 (1.51, 7.52), p < 0.003) [health and safety domains]. Despite living in a setting with universal health insurance, men with HIV receiving community mental health support had greater unmet need in basic and health domains than HIV-negative men receiving such support. Further research is required to develop and evaluate interventions to best support community-dwelling persons with HIV and mental health disorders.

Abstract
BACKGROUND Hepatitis C is a blood-borne virus primarily spread through sharing of drug-injecting equipment. Approximately 150 million people worldwide and 230,000 Australians are living with chronic hepatitis C infection. In March 2016, the Australian government began subsidizing direct acting antivirals (DAAs) for the treatment of hepatitis C, which are highly effective (95% cure rate) and have few side effects. However, there is limited evidence to inform the provision of adherence support to people with hepatitis C on DAAs including the level of medication adherence required to achieve a cure. METHODOLOGY In February 2016, a steering committee comprising four authors convened an expert panel consisting of six hepatology nurses, a hepatologist, a pharmacist, a consumer with hepatitis C and treatment experience, and a consumer advocate. The expert panel focused on the following criteria: barriers and enablers to DAA adherence; assessment and monitoring of DAA adherence; components of a patient-centered approach to DAA adherence; patients that may require additional adherence support; and interventions to support DAA adherence. The resultant guidelines underwent three rounds of consultation with the expert panel, Australasian Hepatology Association (AHA) members (n=12), and key stakeholders (n=7) in June 2016. Feedback was considered by the steering committee and incorporated if consensus was achieved. RESULTS Twenty-four guidelines emerged from the evidence synthesis and expert panel discussion. The guidelines focus on the pretreatment assessment and education, assessment of treatment readiness, and monitoring of medication adherence. The guidelines are embedded in a patient-centered approach which highlights that all patients are at risk of nonadherence. The guidelines recommend implementing interventions focused on identifying patients' memory triggers and hooks; use of nonconfrontational and nonjudgmental language by health professionals; and objectively monitoring adherence. CONCLUSION These are the first guidelines to support patients and health professionals in the delivery of clinical care by identifying practical adherence support interventions for patients taking DAAs.

Abstract
Deep tissue infection is a serious sequela that often demands intravenous (IV) antibiotic treatment. With respect to IV drug users (IDU's), research and lived experience demonstrates a trend of failed treatment outcomes, most notably associated with leaving hospital against medical advice (LAMA) prior to treatment completion, increased adverse outcomes and patient hardship. This paper examines an alternative model for delivering and completing IV antibiotic treatment to IDU's in a community care setting. A retrospective study was designed to review client characteristics. A total of 33 in-depth interviews were conducted with clients, clinicians and with staff. The impact of treatment adherence and completion, as well as client satisfaction of care was explored. A total of 165 patients were admitted during the study period. Osteomyelitis was the primary cause for IV antibiotics. Risk of leaving AMA was significantly lower for community model (p value <0.0000). Qualitative narrative analysis is also described with respect to satisfaction, stigma and the need for better models of care. With lower rates of LAMA a community model ought to be considered on a wider scale for provision of comprehensive support for populations with complex underlying health needs.

Abstract
Approximately 4.1 million Americans have been infected with HCV and 45-85% of chronically infected persons are unaware of their status. Rapid anti-HCV assays can assist and expedite the identification of those unaware of their infection. Performance characteristics of pre-market rapid anti-HCV assays (Chembio, MedMira and OraSure) have been evaluated. Their sensitivity (78.9-99.3%) and specificity (80-100%) varied. Future investigations could include evaluation of rapid anti-HCV tests in persons who are coinfected with HCV and HIV, and development of rapid HCV-antigen tests and nucleic acid tests.

Field-based performance of three pre-market rapid hepatitis C virus antibody assays in STAHR (Study to Assess Hepatitis C Risk) among young adults who inject drugs in San Diego, CA. J Clin Virol 2012; 54:213-7. [PMID: 22560051 DOI: 10.1016/j.jcv.2012.04.003] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 04/04/2012] [Accepted: 04/11/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND Approximately 4.1 million Americans are estimated to have been infected with hepatitis C virus (HCV), 45-85% of whom are unaware of their infection. Persons who inject drugs (PWID) account for 55.8% of all persons with HCV antibody (anti-HCV) in the U.S. PWID have limited access to healthcare and are infrequently tested for anti-HCV using conventional laboratory assays. OBJECTIVE To evaluate performance characteristics (sensitivity and specificity) of three, pre-market rapid point-of-care tests (one oral fluid and two finger-stick assays) from two manufacturers (Chembio and MedMira) in settings providing services to young adult PWID in San Diego, CA. STUDY DESIGN Behavioral risk assessment surveys and testing for HCV were conducted among persons who reported injection drug use (IDU) within the past 6 months as part of the Study to Assess Hepatitis C Risk (STAHR) among PWID aged 18-40 years in 2009-2010. Sensitivity and specificity of the rapid anti-HCV assays were evaluated among STAHR participants, using two commonly used testing algorithms. RESULTS Variability in sensitivity (76.6-97.1%) and specificity (99.0-100.0%) was found across assays. The highest sensitivity achieved for the Chembio finger-stick blood, Chembio oral fluid and MedMira finger-stick blood tests was 97.1%, 85.4% and 80.0% respectively; the highest specificity was 99.0%, 100.0% and 100.0%, respectively. In multivariate analysis false negative anti-HCV results were associated with female sex for the MedMira blood assay. CONCLUSIONS Sensitive anti-HCV rapid assays are appropriate and feasible for high-prevalence, high-risk populations such as young PWID.

Reliability and predictive validity of a hepatitis-related symptom inventory in HIV-infected individuals referred for Hepatitis C treatment. AIDS Res Ther 2011; 8:29.

Abstract
Background We aimed to determine the reliability and validity of a hepatitis symptom inventory and to identify predictors of hepatitis C (HCV) treatment initiation in a cohort of HIV-infected patients. Methods Prospective clinic based study that enrolled patients referred for HCV therapy consideration. A hepatitis symptom inventory and the Center for Epidemiologic Studies Depression Scale (CES-D) were administered to HIV/HCV individuals. The symptom inventory was factor analyzed and subscale reliability estimated with Cronbach's alpha. Predictive validity was evaluated using generalized estimating equations (GEE). Predictors of HCV treatment were identified using logistic regression. Results Between April 2008 to July 2010, 126 HIV/HCV co-infected patients were enrolled in the study. Factor analysis using data from 126 patients yielded a three-factor structure explaining 60% of the variance for the inventory. Factor 1 (neuropsychiatric symptoms) had 14 items, factor 2 (somatic symptoms) had eleven items, and factor 3 (sleep symptoms) had two items, explaining 28%, 22% and 11% of the variance, respectively. The three factor subscales demonstrated high intrinsic consistency reliability. GEE modeling of the 32 patients who initiated HCV therapy showed that patients developed worsening neuropsychiatric and somatic symptoms following HCV therapy with stable sleep symptoms. Bivariate analyses identified the following as predictors of HCV therapy initiation: lower HIV log10 RNA, lower scores for neuropsychiatric, somatic and sleep symptoms, lower CES-D scores and white ethnicity. In stepwise multiple logistic regression analysis, low neuropsychiatric symptom score was the strongest independent predictor of HCV therapy initiation and HIV log10 RNA was inversely associated with a decision to initiate HCV treatment. Conclusions A 41-item hepatitis-related symptom inventory was found to have a clinically meaningful 3-factor structure with excellent internal consistency reliability and predictive validity. In adjusted analysis, low neuropsychiatric symptom scores and controlled HIV infection were independent predictors of HCV treatment initiation. The usefulness of the HCV symptom inventory in monitoring HCV treatment should be evaluated prospectively.

Abstract
BACKGROUND Sustained virologic response to peginterferon plus ribavirin reduces liver-related complications and mortality in patients co-infected with HIV and hepatitis C virus. Therefore, the presence of any barriers to start hepatitis C virus therapy should be identified and eliminated in order to recruit all eligible patients. METHODS Cross-sectional study. In a HIV referral clinic we assessed the proportion of patients eligible for hepatitis C virus evaluation and treatment according to consensus guidelines. RESULTS We identified 134 patients with hepatitis C virus and HIV co-infection. Twenty-one patients were excluded from the analysis due to never attending the HIV clinic (n=12) or having hepatitis C virus RNA not detectable (n=9). In the remaining 113 patients, only 61% had identification of hepatitis C virus genotype and quantification of hepatitis C viral load. Thirty-six patients started peginterferon plus ribavirin, and 16 (44%) achieved sustained virologic response. Seventy-seven patients did not receive treatment for hepatitis C virus due to the presence of medical contraindications (n=22), provider barriers (n=15), or patient barriers (n=40). Multivariate analysis identified lower education degree (odds ratio: 4.53; 95% confidence intervals: 1.36-15.16, p=0.014) and patient civil status single, separated or widower (odds ratio: 4.81; 95% confidence intervals: 1.54-14.99, p=0.007) as the independent determinants associated to not initiating therapy for hepatitis C virus infection in patients with barriers. CONCLUSION A minor proportion of HIV-infected patients received appropriate assessment and treatment for hepatitis C virus infection. Social disadvantages require multidisciplinary models of health care to improve hepatitis C virus treatment initiation and success.

Abstract
Background Injecting drug users (IDU) remain an important population at risk for blood-borne infections such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV). In the Netherlands, a program is being implemented to offer annual voluntary screening for these infections to opioid drug users (ODUs) screened in methadone care. At two care sites where the program is now operating, our study aimed to estimate the seroprevalence among ODUs screened for HIV, HBV and HCV; to evaluate HBV vaccination coverage; and to assess the feasibility of monitoring seroprevalence trends by using routine annual screening data. Methods Opioid drug users on methadone treatment are routinely offered voluntary screening for infectious diseases such as HIV, HBV and HCV. Data on uptake and outcome of anti-HIV, anti-HBc, and anti-HCV screening among ODUs receiving methadone were obtained from two regions: Amsterdam from 2004 to 2008 and Heerlen from 2003 to 2009. Findings Annual screening uptake for HIV, HBV and HCV varied from 34 to 69%, depending on disease and screening site. Of users screened, 2.5% were HIV-positive in Amsterdam and 11% in Heerlen; 26% were HCV-positive in Amsterdam and 61% in Heerlen. Of those screened for HBV, evidence of current or previous infection (anti-HBc) was found among 33% in Amsterdam and 48% in Heerlen. In Amsterdam, 92% were fully vaccinated for HBV versus 45% in Heerlen. Conclusion Annual screening for infectious diseases in all ODUs in methadone care is not fully implemented in the Netherlands. On average, more than half of the ODUs in methadone care in Heerlen and Amsterdam were screened for HIV, HBV and HCV. In addition, screening data indicate that HBV vaccination uptake was rather high. While the HIV prevalence among these ODUs was relatively low compared to other drug-using populations, the high HCV prevalence among this group underscores the need to expand annual screening and interventions to monitor HIV, HBV and HCV in the opioid drug-using population.

Abstract
OBJECTIVE Project RESPECT's brief risk reduction counseling (BRRC) reduced sexual risk and bacterial STIs among at-risk heterosexuals and has been packaged for use with this population. We assessed BRRC's efficacy with RESPECT participants who used drugs and examined BRRC's applicability to present-day users of heroin, cocaine, speedball, or crack. METHODS We compared baseline demographic and economic variables, risk behaviors, and prevalence and correlates of bacterial STIs for ever-injectors ([EIs], N=335) and never-injectors ([NIs], N=3963). We assessed changes in risk behaviors and bacterial STIs for EIs and NIs at 12 months. We compared prevalence of HSV-2, hepatitis B core antigen virus (HBV), hepatitis C virus (HCV), and trichomonas among EIs with recently reported rates among drug users. RESULTS At baseline, 19% of EIs and 29% of NIs had bacterial STIs. Both groups had similar baseline STI correlates. At 12 months, 4% of EIs and 7% of NIs had bacterial STIs. Twelve-month cumulative incidence of bacterial STIs in BRRC was 21% lower among EIs and 18% lower among NIs compared to the informational condition. At 12 months, EIs reported fewer sexual risk behaviors than at baseline. Baseline positivity rates of trichomoniasis in EIs (female: 15%) and in male and female EIs of HSV-2 (39%, 68%), HBV (41%, 37%), and HCV (60%, 58%) were similar to rates in present-day drug users. CONCLUSION Efficacy of BRRC in reducing sexual risk and bacterial STIs in EIs, and similar profiles for EIs and present-day drug users suggest evaluating BRRC with present-day drug users.

Abstract
BACKGROUND Treatment of hepatitis C virus (HCV) infection with pegylated interferon/ribavirin achieves sustained virological response in up to 56% of HCV mono-infected patients and 40% of HCV/human immunodeficiency virus (HIV)-co-infected patients. The relationship of patient adherence to outcome warrants study. AIM To review comprehensively research on patient-missed doses to HCV treatment and discuss applicable research from adherence to HIV antiretroviral therapy. METHODS Publications were identified by PubMed searches using the keywords: adherence, compliance, hepatitis C virus, interferon and ribavirin. RESULTS The term 'non-adherence' differs in how it is used in the HCV from the HIV literature. In HCV, 'non-adherence' refers primarily to dose reductions by the clinician and early treatment discontinuation. In contrast, in HIV, 'non-adherence' refers primarily to patient-missed doses. Few data have been published on the rates of missed dose adherence to pegylated interferon/ribavirin and its relationship to virological response. CONCLUSIONS As HCV treatment becomes more complex with new classes of agents, adherence will be increasingly important to treatment success as resistance mutations may develop with suboptimal dosing of HCV enzyme inhibitors. HIV adherence research can be applied to that on HCV to establish accurate methods to assess adherence, investigate determinants of non-adherence and develop strategies to optimize adherence.

Abstract
Hepatitis C virus (HCV) infection is a major source of morbidity and mortality among substance users and persons living with human immunodeficiency virus (HIV) infection. Treatment for chronic HCV infection involves complex decision-making. These decisions are even more complicated in persons with HIV and substance use related problems. A secondary analyses of qualitative data collected in the United States (2004-2005) with 31 HIV/HCV coinfected adults (48% women; mean age 44.7 years) revealed three themes related to substance use (substance use evolution, revolving door: going back out and reconstructing life) and two HCV treatment decision-making themes (HCV infection treatment issues: not a priority, fear, misinformation and get clean and try it). Study limitations and implications are discussed.

Abstract
OBJECTIVE To determine expert clinical practice in the management of psychiatric status of HIV/hepatitis C virus (HCV)-coinfected patients initiating pegylated interferon/ribavirin for the treatment of hepatitis C. METHOD Two hundred thirty-six expert providers were identified and invited by email to complete an online anonymous survey. RESULTS Ninety-two providers (39%) completed the survey, 24 (26%) of whom are psychiatrists. More than one third of providers indicate that they use or offer the option of antidepressant use prophylactically in HIV-positive patients with no past or current depression beginning HCV treatment, and more than three quarters do so in patients with a history of depression but no current symptoms of depression. The most experienced nonpsychiatrist providers were more likely to use antidepressants prior to the start of treatment in HIV-coinfected patients as compared to in HCV monoinfected patients. There is consensus among providers to leave psychiatric medication unchanged in patients currently treated for unipolar depression. CONCLUSIONS Many expert providers prescribe antidepressants to HIV/HCV-coinfected patients initiating Hepatitis C treatment in the absence of symptoms of depression, despite the lack of data supporting this approach in this population. Research is needed to provide an evidence base to guide the optimal psychiatric management of HIV/HCV-coinfected patients beginning hepatitis C treatment.

Abstract
We characterized hepatitis C virus (HCV) treatment knowledge, experience and barriers in a cohort of community-based injection drug users (IDUs) in Baltimore, MD. In 2005, a questionnaire on HCV treatment knowledge, experience and barriers was administered to HCV-infected IDUs. Self-reported treatment was confirmed from medical records. Of 597 participants, 71% were male, 95% African-American, 31% HIV co-infected and 94% were infected with HCV genotype 1; 70% were aware that treatment was available, but only 22% understood that HCV could be cured. Of 418 who had heard of treatment, 86 (21%) reported an evaluation by a provider that included a discussion of treatment of whom 30 refused treatment, 20 deferred and 36 reported initiating treatment (6% overall). The most common reasons for refusal were related to treatment-related perceptions and a low perceived need of treatment. Compared to those who had discussed treatment with their provider, those who had not were more likely to be injecting drugs, less likely to have health insurance, and less knowledgeable about treatment. Low HCV treatment effectiveness was observed in this IDU population. Comprehensive integrated care strategies that incorporate education, case-management and peer support are needed to improve care and treatment of HCV-infected IDUs.

Abstract
Injection drug use (IDU) accounts for 75% of incident cases of hepatitis C virus (HCV) infection in the developed world. Of those infected with HCV, up to 80% will go on to develop chronic disease. Intervention with effective treatment in eligible subjects will limit the impact of the long-term consequences of infection. The use of combination therapy with pegylated interferon and ribavirin may lead to a cure in up to 80% of treated individuals who carry genotype 2 or 3 isolates. Such individuals account for up to 45% of certain cohorts, such as in the inner city of Vancouver. Historically, many IDUs have not received treatment for HCV infection even if it were medically indicated. Recent data (including our own) suggest that, in the right context, response rates similar to those reported in clinical trials of HCV therapy can be achieved in IDUs, even with ongoing drug use. This is all the more important given that prior infection may protect against re-infection even in the presence of ongoing risk behaviors for HCV transmission. The keys to a successful program appear to be appropriate patient selection as well as the delivery of care within an appropriate setting, preferably with a multidisciplinary team in a way that addresses the issue of addiction and other conditions simultaneously. The development of such programs may be quite complex, but the ultimate benefit (for the treated population and for society as a whole) is certainly worth the effort.

Abstract
BACKGROUND Despite demonstrated efficacy in HIV-hepatitis C virus (HCV) coinfection, not all patients initiate, complete or achieve success with HCV antiviral therapy. PATIENTS AND METHODS All HIV-HCV coinfected patient consults received at The Ottawa Hospital Viral Hepatitis Clinic (Ottawa, Ontario) between June 2000 and September 2006 were identified using a clinical database. A descriptive analysis of primary and contributing factors accounting for why patients did not initiate HCV therapy, as well as the therapeutic outcomes of treated patients, was conducted. RESULTS One hundred two consults were received. Sixty-seven per cent of patients did not initiate HCV therapy. The key primary reasons included: HIV therapy was more urgently needed (22%), loss to follow-up (12%), patients were deemed unlikely to progress to advanced liver disease (18%) and patient refusal (12%). Many patients had secondary factors contributing to the decision not to treat, including substance abuse (23%) and psychiatric illness (14%). Overall, 59% of untreated patients (40 of 68) were eventually lost to follow-up. Thirty-three per cent of referred patients started HCV therapy. Twenty-seven of 42 courses (64%) were interrupted prematurely for reasons such as virological nonresponse (48%), psychiatric complications (10%) and physical side effects (7%). Of all treatment recipients, 12 of 42 full courses of therapy were completed and three remained on HCV medication. Overall, eight of the 102 coinfected patients studied (8%) achieved a sustained virological response. DISCUSSION Not all HIV-HCV coinfected patients who are deemed to be in need of HCV treatment are initiating therapy. Only a minority of patients who do receive treatment achieve success. Implementation of HIV treatment, patient retention, attention to substance abuse and mental health care should be the focus of efforts designed to increase HCV treatment uptake and success. This can be best achieved within a multidisciplinary model of health care delivery.

Abstract
AIMS Hepatitis C virus (HCV) infection is a common chronic complication of injection drug use. Methadone maintenance programs contain large numbers of patients infected with HCV. This paper reviews HCV infection with emphasis on the medical care of HCV-infected, or HCV and human immunodeficiency virus co-infected, patients on methadone or buprenorphine maintenance. METHODS Literature searches using PubMed, PsycINFO and SocINDEX were used to identify papers from 1990-present on antiviral therapy for HCV in methadone maintenance patients and on liver transplantation in methadone maintenance patients. RESULTS Injection drug use is the most significant risk factor for HCV infection in most western countries. The prevalence of HCV antibody is high in injection drug users (53-96%) and in patients enrolled in methadone maintenance programs (67-96%). Studies of antiviral therapy for HCV in methadone maintenance patients show rates of sustained virological response (SVR), defined as negative HCV-RNA 24 weeks after the end of treatment, of 28-94%. In studies with contrast groups, no significant differences in SVR between methadone and contrast groups were found. Excellent completion rates of antiviral therapy (72-100%) were found in five of six studies. There are many barriers to methadone maintenance patients' receiving antiviral therapy, and research on overcoming barriers is discussed. Liver transplantation has been successful in methadone maintenance patients but has not been utilized widely. CONCLUSION High quality medical care for all aspects of HCV infection can be provided to methadone maintenance patients. The literature supports the effectiveness of such services, but the reality is that most patients do not receive them.

Abstract
Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus infection. Successful pharmacotherapy for opioid addiction stabilizes patients and improves patient compliance to care and treatment regimens as well as promotes good patient outcomes. Implementation and integration of effective hepatitis prevention programs, care programs, and treatment regimens in concert with the pharmacological therapy of opioid addiction can reduce the public health burdens of hepatitis and injection drug use.

Abstract
Hepatitis C virus (HCV) coinfection in the presence of HIV raises several challenging issues for the treating clinician. Some evidence indicates that concomitant HIV infection alters HCV virology in ways that are relevant for treatment. Pegylated interferon plus ribavirin is the recommended therapy for HCV in HIV-infected patients. Proportionately fewer HIV/HCV-coinfected patients achieve a sustained virologic response (SVR) compared with those infected with HCV alone. Possible reasons for this include higher levels of HCV viremia and inadequate ribavirin exposure. Strategies under study for optimizing therapeutic response include weight-based ribavirin dosing, use of growth factors to avoid dose reduction, and longer duration of therapy. Aggressive management of adverse effects to avoid dose reduction or treatment discontinuation is also crucial. An integrated multidisciplinary team, including a psychiatrist and addictions specialist, can increase the proportion of HIV/HCV-coinfected patients eligible for treatment. Investigational options exist for patients who relapse after treatment is discontinued and for those with a partial virologic response. Promising therapies that are under development include protease and polymerase inhibitors.

Abstract
BACKGROUND AND AIM There are few studies investigating the treatment of hepatitis C virus (HCV) infection in current and former drug users. With this in mind, we sought to evaluate the antiviral efficacy of interferon alpha-2b (IFN alpha-2b) or pegylated-interferon alpha-2b (PEG-IFN alpha-2b) and ribavirin (RBV) in injection drug users (IDU) enrolled in a directly observed therapy (DOT) program, as measured by sustained virologic response (SVR). METHODS Viremic HCV-infected IDU, with alanine aminotransferase (ALT) >1.5x upper limit of normal (ULN) were offered 24-48 week (based on HCV genotype) therapy with RBV (800-1200 mg/day, based on weight) along with IFN alpha-2b (3 million IU thrice weekly) replaced by PEG-IFN alpha-2b (1.5 ìg/kg once weekly) as it became available. All injections were directly observed. The primary endpoint was SVR. RESULTS Overall, 40 patients (33 males) received IFN alpha-2b (12) or PEG-IFN alpha-2b (28), 55% with HCV genotypes 2 or 3. Only 14 discontinued therapy, 5 due to toxicity, 6 due to illicit drug use and 3 did not achieve an early virologic response. In an intent-to-treat analysis, the overall SVR was 55% (22/40), 64% (14/22) in subjects with genotypes 2/3. There was no significant difference in response rates among those with >6 (50%) or <or=6 months (64%) drug abstinence (P = 0.51) or among those with (53%) and without (57%) intercurrent drug use (P = 0.99); however, frequent users (n = 9) had a decreased SVR (22%) when compared with occasional users (n = 10, 80%, P = 0.12). CONCLUSION Treatment of HCV in current and former IDU within a multidisciplinary DOT program can be successfully undertaken, resulting in SVR similar to those in randomized controlled trials.

Treatment uptake and outcomes among current and former injection drug users receiving directly observed therapy within a multidisciplinary group model for the treatment of hepatitis C virus infection. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2007; 18:437-43. [PMID: 17854734 DOI: 10.1016/j.drugpo.2007.01.009] [Citation(s) in RCA: 84] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2006] [Revised: 01/03/2007] [Accepted: 01/06/2007] [Indexed: 01/24/2023]
Abstract
Injection drug use accounts for the majority of incident and prevalent cases of hepatitis C virus (HCV) infection. However, very few injection drug users (IDUs) have received treatment for this condition given issues of medical or psychiatric co-morbidity, ongoing substance abuse and a widely held belief that such individuals will not be able to adhere to the requirements of therapy, including regular medical follow-up. With this in mind, we sought to evaluate HCV treatment uptake and outcomes among current and former IDUs attending a weekly peer support group and receiving directly observed HCV therapy. Utilizing the existing infrastructure for the management of addictive disease, we have developed a model of "one-stop shopping" whereby the treatment of addiction, HCV and other medical conditions are fully integrated, with the collaboration of nurses, counsellors, addiction specialists, infectious disease specialists, primary care physicians and researchers. Subjects interested in receiving treatment for HCV infection were referred to a weekly peer-support group and evaluated for treatment. Patients received therapy with pegylated interferon-alpha2a or -alpha2b, both in combination with ribavirin. All injections were directly observed. Overall, we observed a high uptake of HCV treatment among attendees, with 51 percent either receiving or about to receive therapy. To date, 18 patients have initiated treatment for HCV infection and 12 have completed therapy. Overall, 8/12 (67 percent) subjects achieved an end of treatment response (genotype 1, 67 percent; genotypes 2/3, 67 percent), despite ongoing drug use in 75 percent of patients during treatment. These data demonstrate that with the appropriate programs in place, a high uptake of HCV treatment can be achieved among IDUs referred to a peer-support group. Moreover, the treatment of HCV in current and former IDUs within a multidisciplinary DOT program can be successfully undertaken, resulting in ETRs similar to those reported in randomized controlled trials.

Substance abuse treatment and receipt of liver specialty care among persons coinfected with HIV/HCV who have alcohol problems. J Subst Abuse Treat 2006; 31:411-7. [PMID: 17084795 PMCID: PMC1995458 DOI: 10.1016/j.jsat.2006.05.015] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2005] [Revised: 05/04/2006] [Accepted: 05/16/2006] [Indexed: 12/20/2022]
Abstract
We examined the association of substance abuse treatment with access to liver specialty care among 231 persons coinfected with HIV and hepatitis C virus (HCV) with a history of alcohol problems who were recruited and followed up in the HIV-Longitudinal Interrelationships of Viruses and Ethanol cohort study from 2001 to 2004. Variables regarding demographics, substance use, health service use, clinical variables, and substance abuse treatment were from a standardized research questionnaire administered biannually. We defined substance abuse treatment services as any of the following in the previous 6 months: 12 weeks in a halfway house or residential facility, 12 visits to a substance abuse counselor or mental health professional, day treatment for at least 30 days, or any participation in a methadone maintenance program. Liver specialty care was defined as a visit to a liver doctor, a hepatologist, or a specialist in treating hepatitis C in the past 6 months. At study entry, most of the 231 subjects (89%, n = 205) had seen a primary care physician, 50% had been exposed to substance abuse treatment, and 50 subjects (22%) had received liver specialty care. An additional 33 subjects (14%) reported receiving liver specialty care during the follow-up period. In the multivariable model, we observed a clinically important although not statistically significant association between having been in substance abuse treatment and receiving liver specialty care (adjusted odds ratio = 1.38; 95% confidence interval = 0.9-2.11). Substance abuse treatment systems should give attention to the need of patients to receive care for prevalent treatable diseases such as HIV/HCV coinfection and facilitate its medical care to improve the quality of care for individuals with substance use disorders. The data illustrate the need for clinical care models that give explicit attention to the coordination of primary health care with addiction and hepatitis C specialty care while providing ongoing support to engage and retain these patients with complex health needs.

Abstract
OBJECTIVE To evaluate predictors and trends of referral for hepatitis C virus (HCV) care, clinic attendance and treatment in an urban HIV clinic. DESIGN AND METHODS A retrospective cohort analysis in which 845 of 1318 co-infected adults who attended the Johns Hopkins HIV clinic between 1998 and 2003 after an on-site viral hepatitis clinic was opened, attended regularly (>/= 1 visit/year for >/= 2 years). Logistic regression was used to examine predictors of referral. RESULTS A total of 277 (33%) of 845 were referred for HCV care. Independent predictors of referral included percentage elevated alanine aminotransferase levels [adjusted odds ratio (AOR) for 10% increase,1.16; 95% confidence interval (CI), 1.10-1.22] and CD4 cell count > 350 cells/microl (AOR, 3.20; 95% CI, 2.10-4.90), while injection drug use was a barrier to referral (AOR, 0.26; 95% CI, 0.11-0.64). Overall referral rate increased from < 1% in 1998 to 28% in 2003; however, even in 2003, 65% of those with CD4 cell count > 200 cells/microl were not referred. One hundred and eighty-five (67%) of 277 referred kept their appointment, of whom 32% failed to complete a pre-treatment evaluation. Of the remaining 125, only 69 (55%) were medically eligible for treatment, and 29 (42%) underwent HCV treatment. Ninety percent of 29 were infected with genotype 1 and 70% were African American; six (21%) achieved sustained virologic response (SVR). Only 0.7% of the full cohort achieved SVR. CONCLUSIONS Although the potential for SVR and the recent marked increase in access to HCV care are encouraging, overall effectiveness of anti-HCV treatment in this urban, chiefly African American, HCV genotype 1 HIV clinic is extremely low. New therapies and treatment strategies are an urgent medical need.

Abstract
BACKGROUND Alcohol use and human immune deficiency virus (HIV) infection are both associated with accelerated progression of hepatitis C virus (HCV) disease and reduced response rates to interferon therapy. In this study, we assessed the prevalence of barriers to interferon treatment in a population of HIV/HCV-coinfected patients with current or past alcohol problems and the extent to which they received treatment to address the barriers. METHODS This is a cross-sectional, descriptive analysis of baseline data from a prospective study assessing the impact of HCV and alcohol use on HIV disease progression. Using consensus guidelines, subjects were categorized as having absolute, relative, or no contraindications to interferon therapy for HCV. Absolute contraindications to treatment included heavy alcohol use, decompensated liver disease, CD4 cell count <100 cells/microL, recent needle sharing, and suicidal ideation. Relative contraindications included moderate alcohol use, recent injection drug use, depressive symptoms, and CD4 cell count from 100 to 199 cells/microL. RESULTS Of 401 HIV-infected subjects, 200 were HCV RNA-positive. Fifty-three percent had an absolute contraindication to interferon therapy, 35% a relative but no absolute contraindication, and only 12% had no contraindication. Of those with an absolute contraindication, 61% reported heavy drinking and the majority (88%) had multiple contraindications. These contraindications were present despite the fact that over 50% were in receipt of substance abuse and mental health treatment. CONCLUSIONS Continued alcohol and drug use as well as depressive symptoms are the major barriers to interferon therapy in HCV/HIV-coinfected subjects and these barriers persist despite high treatment rates for these problems. Therefore, more intensive treatments of alcohol, drug, and mental health issues are needed to improve HCV treatment eligibility in HCV/HIV-coinfected persons.

Abstract
Pharmacotherapy for substance abuse is a rapidly evolving field comprising both old and new effective treatments for substance use. Opiate agonist therapy has been shown to diminish and often eliminate opiate use. This behavior change has resulted in the reduced transmission of many infections, including HIV, hepatitis C virus (HCV), and an enhanced quality of life. For the past 35 years, the provision of opioid agonist therapy has been limited to opioid treatment programmes. Opioid treatment programmes treat approximately 200,000 of the estimated million opiate-addicted individuals in the United States. With the need to increase the number of treatment opportunities available for opioid-dependent patients, Congress passed the Drug Addiction Treatment Act of 2000, which allows for the treatment of opioid dependence using buprenorphine by a properly licensed physician, including HIV primary care physicians. The integration of buprenorphine treatment for opioid addiction into HIV primary care thus provides a new treatment paradigm to address substance abuse in patients with HIV and HCV infections.

Abstract
Injection drug use accounts for most of the incident infections with hepatitis C virus (HCV) and for at least one-third of new human immunodeficiency virus (HIV) infections. Coinfection with HCV and HIV presents complex and challenging medical conditions. Ensuring access to and maintaining care for HIV and HCV for drug users presents special challenges to the health care team that require a nonjudgmental attitude, experience, and patience. Care for HCV infection, however, can be used as an instrument to engage drug-using persons in ongoing primary care relationships. Common elements to both care for HCV infection and primary care for HIV infection are testing for and counseling about HCV and HIV, substance abuse and mental health services, social support, and subspecialty referral. These elements, in particular treatment for substance abuse, can be focal points for model care systems that provide integrative care for both HCV and HIV infections.
