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.

J Urban Health 2008; 85:228-38. [PMID: 18274908 PMCID: PMC2430122 DOI: 10.1007/s11524-008-9253-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2007] [Accepted: 01/03/2008] [Indexed: 10/22/2022]
Abstract
Homeless youth are at increased risk for hepatitis B virus (HBV) infection and HBV vaccine coverage is poor in this group. The purpose of our study was to determine if a shelter-based HBV vaccine program in children and adolescents 2-18 years of age with a randomized controlled trial using a culturally appropriate HBV video could increase HBV vaccine coverage rates. Subjects were randomized to an 8 min HBV video or a control, smoking prevention video. Before exposure to the videos, HBV knowledge, and demographics were assessed in caregivers and adolescents. HBV vaccine no. 1 was offered to all subjects who did not produce a vaccine record; subsequently, an accurate HBV vaccine history was obtained from medical providers. Subjects were asked to return 1 and 3 months after visit 1, HBV vaccine was offered to all with incomplete coverage, and HBV knowledge was reassessed. There were 328 children and adolescents cared for by 170 caregivers enrolled in the study. One hundred and four had incomplete HBV vaccine coverage. Data are reported for all family units with at least one subject needing vaccine. There were 53 children and adolescents randomized to the HBV video vs. 51 to the smoking video. HBV knowledge scores of caregivers improved at Visit no. 2 vs. no. 1 in the HBV video group (p = 0.01) but not in the smoking group (p = 0.82). Similar results were observed for adolescents in the HBV video group (p = 0.05) but not in the smoking group (p = 0.40). Exposure to the HBV video vs the smoking video had a significant effect on return rates for vaccine at Visit no. 2 (59 vs. 31%; p = 0.05) but not at Visit no. 3 (47 vs. 18%, p = 0.06). The shelter-based vaccine program was very effective in increasing HBV coverage rates in the entire group of 328 children and adolescents enrolled in the study, from 68% coverage at baseline to 85% at the conclusion of the study. We conclude that shelter-based HBV vaccine programs can be highly effective in increasing vaccine coverage rates in older children and adolescents. A brief exposure to a culturally appropriate HBV video improves HBV knowledge and may improve return rates for vaccine.

Abstract
OBJECTIVES Few studies of hepatitis B virus (HBV) infection and hepatitis B vaccination have focused on women, and specifically, women who are at high risk. This study was designed to assess the extent of HBV infection and vaccination, level of knowledge about hepatitis B, motivators and barriers to accepting vaccination and uptake of hepatitis B vaccine. DESIGN From March 2005 to June 2006, 402 HIV-negative noninjection drug-using women at sexual risk were recruited, interviewed, and tested for markers of HBV infection. RESULTS Based on serologic testing, 16.7% were previously vaccinated against HBV, 31.1% were previously infected and 52.2% were still susceptible to HBV. Knowledge of HBV infection, transmission, and prevention was low with a mean of 6.1 of 12 knowledge items correctly identified as true or false; a substantial percent of women were not sure of the correct answer. Of the women still susceptible, 69.0% started the hepatitis B vaccine series after counseling given through the study. CONCLUSION This study illustrates that there continues to be gaps in current strategies for administering hepatitis B vaccine among female populations at sexual risk. Interventions are needed for this population to increase awareness and knowledge of hepatitis B, its transmission, impact on health and the availability of a safe and effective vaccine, supplemented by community programs for adult vaccination.

Abstract
BACKGROUND Despite CDC recommendations to vaccinate injection drug users (IDUs) against hepatitis A virus (HAV) and hepatitis B virus (HBV) infections, coverage remains low. Vaccination programs convenient to IDUs have not been widely implemented or evaluated. We assessed whether convenience and monetary incentives influenced uptake of free vaccine by 18-30-year-old IDUs in five U.S. cities. METHODS IDUs recruited from community settings completed risk behavior self-interviews and testing for antibodies to HAV (anti-HAV) and hepatitis B core antigen (anti-HBc). Vaccine was offered presumptively at pre-test (except in Chicago); on-site availability and incentives for vaccination differed by site, creating a quasi-experimental design. RESULTS Of 3181 participants, anti-HAV and anti-HBc seroprevalence was 19% and 23%, respectively. Although 83% of participants were willing to be vaccinated, only 36% received > or =1 dose, which varied by site: Baltimore (83%), Seattle (33%), Los Angeles (18%), New York (17%), and Chicago (2%). Participation was highest when vaccine was available immediately on-site and lowest when offered only after receiving results. Monetary incentives may have increased participation when on-site vaccination was not available. CONCLUSION IDUs were willing to be vaccinated but immediate, on-site availability was critical for uptake. Convenience should be a key consideration in designing strategies to increase vaccine coverage among IDUs.

Abstract
The prevalence of vaccination against hepatitis B virus (HBV), factors associated with vaccination, and missed opportunities for vaccination were assessed among 949 street-recruited young injecting heroin users (IHUs) and noninjecting HUs (NIHUs). A cross-sectional study was carried out in Madrid, Barcelona, and Seville. Face-to-face interviews were held using a structured questionnaire with computer-assisted personal interviewing. Dried blood spot samples were tested for anti-HBV core antigen and HBV surface antigen. Bivariate and logistic regression analyses were performed. The prevalence of HBV vaccination was 21.7%, with significant differences among the cities (13.3% in Madrid, 18.4% in Seville, and 33.2% in Barcelona) and between IHUs (23.8%) and NIHUs (17.9%). In the logistic regression analysis, living in Barcelona and being aged 25 years or younger were associated with HBV vaccination in IHUs and NIHUs; in IHUs, vaccination was also associated with living in the street or in institutions for most of the last 12 months. Practically all those susceptible to HBV infection had missed at least one opportunity for vaccination, and most of them had missed such an opportunity in the last year. The proportion of vaccinated HUs remains very low despite efforts to set up harm reduction programs. New and more active strategies must be incorporated in these programs.

Abstract
In 1999, the Department of Health allocated additional funding to Health Authorities in England to expand hepatitis B immunization among injecting drug users (IDUs), with the aim of increasing coverage by 20%. In 2001, a vaccination programme for prison inmates in England was also instigated. Between 1998 and 2004 current IDUs participated in a series of annual unlinked anonymous surveys that recorded vaccine uptake (n = 11 383). The proportion self-reporting vaccine uptake rose significantly from 27% in 1998 to 59% in 2004 [adjusted odds ratio: 3.7 (95% CI 3.2-4.3); increase in uptake of 25% per annum (95% CI 22-27%)]. A second survey, which recruited 852 current IDUs from community settings in 2003/04, found that prisons were the most common source (38%) of vaccine doses, followed by drug services (28%) and general practitioners (17%), with only 14% receiving doses through needle exchanges. These data suggest that the 20% target of improving vaccination coverage has been met, with the prison vaccination programme likely to have made a substantive contribution in recent years. However, prevalence of antibodies to the hepatitis B core antigen was stable (21%) and is currently similar among the vaccinated and unvaccinated. Consideration needs to be given to improving community vaccination provision for IDUs, targeting recent initiates, and determining when surveillance data should indicate reductions in infection so that the effectiveness of the targeted strategy can be assessed.

Abstract
Injection drug use (IDU) plays a critical role in the HIV epidemic in several countries throughout the world. In these countries, injection drug users are at significant risk for both HIV and tuberculosis, and active IDU negatively impacts treatment access, adherence and retention. Comprehensive strategies are therefore needed to effectively deliver preventive, diagnostic and curative services to these complex patient populations. We propose that developing co-located integrated care delivery systems should become the focus of national programmes as they continue to scale-up access to antiretroviral medications for drug users. Existing data suggest that such a programme will expand services for each of these diseases; increase detection of tuberculosis (TB) and HIV; improve medication adherence; increase entry into substance use treatment; decrease the likelihood of adverse drug events; and improve the effectiveness of prevention interventions. Key aspects of integration programmes include: co-location of services convenient to the patient; provision of effective substance use treatment, including pharmacotherapies; cross-training of generalist and specialist care providers; and provision of enhanced monitoring of drug-drug interactions and adverse side effects. Central to implementing this agenda will be fostering the political will to fund infrastructure and service delivery, expanding street-level outreach to IDUs, and training community health workers capable of cost effectively delivering these services.

Abstract
Twinrix is the only licensed vaccine that provides dual protection against infection with hepatitis A virus (HAV) and hepatitis B virus (HBV). The standard vaccination schedule for Twinrix is 0, 1 and 6 months. However, many high-risk populations, such as injecting drug users (IDUs), do not complete the vaccination series and, thus, do not acquire sufficient immunity against HAV and HBV. Twinrix can be administered using an accelerated vaccination schedule of 0, 7 and 21 days, with a booster recommended at 12 months. This manuscript reviews the available literature on vaccinating IDUs against HAV and HBV. The authors conclude that there is insufficient evidence regarding whether the accelerated Twinrix HAV/HBV vaccination schedule would yield a greater number of IDUs protected against both HAV and HBV.

Abstract
BACKGROUND Comprehensive preventive services are recommended for injection drug users (IDU), including screening tests, vaccinations, risk reduction counseling, and sterile syringes. Syringe exchange programs (SEP) may facilitate receipt of preventive services by IDUs, but whether SEP clients receive recommended preventive care is not known. We examined use of recommended preventive services by clients of 23 SEPs throughout California. METHODS Five hundred and sixty SEP clients were recruited from 23 SEPs throughout California between March and September 2003. Receipt of 10 recommended preventive services and source of care (SEP versus non-SEP providers) was ascertained from client interviews. RESULTS On average, SEP clients received only 13% of recommended preventive services and 49% of clients received none of the recommended services. Of services that were received, 76% were received from SEPs. In multivariate analysis, use of drug treatment and more frequent SEP visits were associated with receipt of recommended preventive services by clients. CONCLUSIONS SEPs are often the only source of preventive care for their IDU clients. Still, SEP clients fail to receive most recommended preventive services. Interventions to increase use of preventive services and improve the quality of preventive care received by IDUs, such as increased access to drug treatment and SEPs, are needed.
