RESUMO
Prisoners engage in a range of risk behaviors that can lead to the transmission of viral infections, such as HIV, hepatitis B and hepatitis C. In this review, we summarize the epidemiologic literature from 2007 to 2017 on 4 key risk behaviors for human immunodeficiency virus and hepatitis C virus among prisoners globally: drug injection, sexual activity, tattooing, and piercing. Of 9,303 peer-reviewed and 4,150 gray literature publications, 140 and 14, respectively, met inclusion criteria covering 53 countries (28%). Regions with high levels of injection drug use were Asia Pacific (20.2%), Eastern Europe and Central Asia (17.3%), and Latin America and the Caribbean (11.3%), although the confidence interval for Latin America was high. Low levels of injection drug use in prison were found in African regions. The highest levels of sexual activity in prison were in Europe and North America (12.1%) and West and Central Africa (13.6%); low levels were reported from the Middle East and North African regions (1.5%). High levels of tattooing were reported from Europe and North America (14.7%), Asia Pacific (21.4%), and Latin America (45.4%). Prisons are burdened with a high prevalence of infectious diseases and risk behaviors for transmission of these diseases, and, commonly, a striking lack of evidence-based infection control measures, even when such measures are available in the surrounding community. Given that most prisoners return to these communities, failure to implement effective responses has repercussions not only prisoner health but also for public health.

Smoking tobacco contributes to 11.5% of deaths worldwide and, in some countries, more hospitalizations than alcohol and drugs combined. Globally in 2015, 25% of men and 5% of women smoked. In the United States, a higher proportion of people in prison smoke than do community-dwelling individuals. To determine smoking prevalence in prisons worldwide, we systematically reviewed the literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines; we also examined whether prisons banned smoking or treated smokers. We searched databases for articles published between 2012 and 2016 and located 85 relevant articles with data representing 73.5% of all incarcerated persons from 50 countries. In 35 of 36 nations (97%) with published prevalence data, smoking for the incarcerated exceeded community rates 1.04- to 62.6-fold. Taking a conservative estimate of a 2-fold increase, we estimated that, globally, 14.5 million male and 26,000 female smokers pass through prisons annually. Prison authorities' responses include permitting, prohibiting, or treating tobacco use. Bans may temporarily improve health and reduce in-prison health care costs but have negligible effect after prison release. Evidence-based interventions for smoking cessation effective outside prisons are effective inside; effects persist after release. Because smoking prevalence is heightened in prisons, offering evidence-based interventions to nearly 15 million smokers passing through yearly would improve global health.

The value of hair analysis in measuring treatment outcome was examined in a randomised controlled trial (RCT) of an Australian state prison-based methadone programme between 1997 and 1998 (n = 382 male prisoners). Hair samples were analysed for morphine using immunoassay techniques. Agreement between hair analysis and self-report was tested using kappa, McNemar's test of symmetry and Pearson's correlation coefficient r. Hair analysis based on immunoassay was inadequate as the primary outcome measure for the RCT but had value in supplementing self-reported heroin use. There was a modest correlation (r = 0.31, p < 0.001) between self-reported frequency of heroin use and morphine concentrations in hair. Sectional hair analysis, a reflection of duration of drug use, was uninformative and generally impractical due to the length of hair sections needed.

In order to be optimally effective, continuing training programmes for health-care professionals need to be tailored so that they target specific knowledge deficits, both in terms of topic content and appropriate intervention strategies. A first step in designing tailored treatment programmes is to identify the characteristics of the relevant health-care professional group, their current levels of content and treatment knowledge, the estimated prevalence of drug and alcohol problems among their patients and their preferred options for receiving continuing education and training. This study reports the results of a survey of 53 primary care physicians working in Iran. The majority were male, had a mean age of 44 years and saw approximately 94 patients per week. In terms of their patients' drug use, primary care physicians thought most patients with a substance use problem were male, women were most likely to use tobacco (52%), opium (32%) and marijuana/hashish and young people were most likely to use tobacco, alcohol, marijuana and heroin. Counselling and nicotine patches were the treatments most commonly provided. Although the majority (55%) reported referring patients to other services, more than a third did not. Most primary care physicians reported being interested in attending further training on substance abuse issues. The implications of these data for ongoing education and training of primary care physicians in Iran are discussed.
RESUMO
AIMS: To examine the long-term impact of methadone maintenance treatment (MMT) on mortality, re-incarceration and hepatitis C seroconversion in imprisoned male heroin users. DESIGN, SETTING AND PARTICIPANTS: The study cohort comprised 382 imprisoned male heroin users who had participated in a randomized controlled trial of prison-based MMT in 1997/98. Subjects were followed-up between 1998 and 2002 either in the general community or in prison. MEASUREMENTS: All-cause mortality, re-incarceration, hepatitis C and HIV serostatus and MMT retention. FINDINGS: There were no deaths recorded while subjects were enrolled in MMT. Seventeen subjects died while out of MMT, representing an untreated mortality rate of 2.0 per 100 person-years (95% CI, 1.2-3.2). Re-incarceration risk was lowest during MMT episodes of 8 months or longer (adjusted hazard ratio 0.3 (95% CI, 0.2-0.5; P < 0.001), although MMT periods 2 months or less were associated with greatest risk of re-incarceration (P < 0.001). Increased risk of hepatitis C seroconversion was significantly associated with prison sentences of less than 2 months [adjusted hazard ratio 20 (95% CI, 5-76; < P = 0.001)] and MMT episodes less than 5 months [adjusted hazard ratio 4.2 (95% CI, 1.4-12.6; P = 0.01)]. Subjects were at greatest risk of MMT dropout during short prison sentences of 1 month or less (adjusted hazard ratio 10.4 (95% CI, 7.0-15.7; P < 0.001). HIV incidence was 0.3 per 100 person-years (95% CI, 0.03-0.99). CONCLUSIONS: Retention in MMT was associated with reduced mortality, re-incarceration rates and hepatitis C infection. Prison-based MMT programmes are integral to the continuity of treatment needed to ensure optimal outcomes for individual and public health.

BACKGROUND: To explore folk understandings of blood borne virus infection and infectiousness among injecting drug users in Kings Cross, Sydney. METHODS: Observational fieldwork was conducted in Kings Cross over a four month period. In-depth interviews with 24 current injectors and 4 key informants recruited from King Cross were undertaken. RESULTS: Hepatitis C (HCV) generated different meanings from HIV. HIV was considered "the dreaded" and generated fear of infection and dire disease progression. Whereas HCV was considered non-desirable but less threatening than HIV. The risks of transmitting HCV through sharing injecting paraphernalia was poorly understood. Some believed HCV infection was linked to poor hygiene and dirty water. Jaundice was mistakenly thought to indicate HCV infection and was used to gauge infectiousness. Many were confused about their current hepatitis C serostatus. Some participants thought they had a "dormant antibody" or that they had a "mild case" of infection. Participants were unsure what this meant for their own health or for their potential to infect others. CONCLUSION: Participants displayed confusion about transmission risks for hepatitis C, conflating blood awareness and hygiene health promotion messages. Participants' reliance on the symptom of jaundice to gauge serostatus places them at risk of transmitting and contracting HCV. Participants were confused about what a positive HCV diagnosis meant for their own health and their ability to infect others. Education is needed to debunk misconceptions about jaundice and clarify medical terms such as 'antibody' at the time of diagnosis. Further clarification of messages about injecting hygiene and blood awareness are also required.
RESUMO
Young people aged 15-24 years account for fifty percent of all new AIDS cases worldwide. Moreover, half of all new HIV infections are associated with injection drug use. The average age for initiation into injecting drug use is 20 years of age. This paper investigates whether HIV prevention programs have reduced risk behaviours in young people.
RESUMO
The objective of this study was to compare the prevalence of risk factors for hepatitis C virus (HCV) infection among male prison inmates enrolling into a prospective cohort in Australia. We tested 121 inmates who were previously untested or were previously known to be anti-HCV antibody negative for anti-HCV antibodies by enzyme-linked immunosorbent assay. HCV-positive inmates were classified as cases (n = 25) and HCV-negative inmates as controls (n = 96). The study found that cases were less educated than controls and confirmed that prior imprisonment, drug injection, and a longer duration of injecting were risk factors for HCV infection. More than half of those who tested HCV positive perceived that they did not have HCV infection, and 44% were unsure of their HCV status. Those inmates who were incorrect about their HCV status tended to be less educated and were more likely to have been previously imprisoned than those who were correct about their HCV status. Inmates who were unsure of their HCV status were less likely to have been tested for HCV than those who had a clear perception of their HCV status, even if incorrect. Three (12%) inmates who tested positive denied injecting drug use, but reported other risk factors. Prisons are likely to remain an important site for the diagnosis of HCV infection and targeted interventions aimed at risk reduction among inmates with low education levels and a previous imprisonment history.

AIM: To evaluate the effectiveness of an HIV peer training program conducted in a colony for drug dependent male prisoners in Siberia, Russia. METHOD: Questionnaires were used to collect data pre and post peer training sessions. Three peer training sessions were conducted between questionnaires. Fifteen to twenty inmates were trained as peer educators at each week-long health education training session. RESULTS: In 2000 and 2001, 153 and 124 inmates completed the questionnaire respectively. Respondents in both years reported similar health and injecting histories and comparable levels of sexual activity. Respondents in 2001 were significantly more likely to correctly identify both how HIV can and cannot be transmitted compared to respondents in 2000. The prevalence of tattooing in prison decreased significantly between questionnaires. However, there was virtually no reported use of bleach to clean tattooing or injecting equipment in either 2000 or 2001. Access to condoms increased significantly between questionnaires. CONCLUSIONS: While this training program was associated with improved HIV knowledge, the Ministry of Justice should consider improved and additional harm reduction strategies. These include increased availability of bleach and condoms and the introduction of methadone treatment and syringe exchange in prison.
RESUMO
Understanding the earliest virological and immunological events in acute hepatitis C virus (HCV) infection may provide insight into the determinants of protective immunity. Four cases of HCV viremia with subsequent viral clearance, but without biochemical hepatitis or anti-HCV seroconversion, are reported from a prospective cohort study of prison inmates. Two of the subjects who developed sustained viremia were assessed for production of interferon (IFN)- gamma, by use of the enzyme-linked immunospot (ELISPOT) method and by assessment of HCV cytotoxic T lymphocyte (CTL) activity, CD4 lymphocyte proliferative responses, HCV load, and genotype. After 2-6 months of viremia, all 4 subjects cleared serum HCV RNA. Specific cellular responses were detected in both of the subjects who were assessed, and production of IFN- gamma was demonstrated in one subject. All subjects had weak, but consistent, serological reactivity against HCV nonstructural proteins on immunoblot testing, despite repeatedly nonreactive HCV ELISA tests. These cases highlight the potential for cellular immune responses against HCV to facilitate viral clearance, responses that may model those required for effective HCV vaccination.

OBJECTIVES: The aim was to determine whether methadone maintenance treatment reduced heroin use, syringe sharing and HIV or hepatitis C incidence among prisoners. METHODS: All eligible prisoners seeking drug treatment were randomised to methadone or a waitlist control group from 1997 to 1998 and followed up after 4 months. Heroin use was measured by hair analysis and self report; drugs used and injected and syringe sharing were measured by self report. Hepatitis C and HIV incidence was measured by serology. RESULTS: Of 593 eligible prisoners, 382 (64%) were randomised to MMT (n=191) or control (n=191). 129 treated and 124 control subjects were followed up at 5 months. Heroin use was significantly lower among treated than control subjects at follow up. Treated subjects reported lower levels of drug injection and syringe sharing at follow up. There was no difference in HIV or hepatitis C incidence. CONCLUSIONS: Consideration should be given to the introduction of prison methadone programs particular where community based programs exist.

OBJECTIVES: To determine whether infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) occurred after two potential episodes of exposure through needle- and syringe-sharing in Australian prisons, and to examine use of post-exposure prophylaxis (PEP) against HIV infection in the prison setting. DESIGN: Cohort study of potential contacts of two prisoners infected with HIV, HBV and HCV followed up for up to 14 months. SETTING: Two Australian prisons between November 2000 (time of exposure) and December 2001. PARTICIPANTS: Two index patients (both infected with HIV and HCV; one also infectious for HBV) from two different prisons, and 104 inmates who shared needles and syringes. MAIN OUTCOME MEASURES: Seroconversions to HIV, HBV and HCV related to the high-risk exposure and uptake and completion of HIV PEP determined from medical records of inmates. RESULTS: There were four seroconversions to HCV within 14 months of the potential exposure (14% of those susceptible in the cohort), but no recorded HIV or HBV seroconversions. Forty-six inmates (82% of those eligible) were offered PEP, and 34 of these (74%) elected to receive it. Only eight (24% of the 34) completed the full PEP course. CONCLUSIONS: HCV transmission in the prison setting is related to high-risk needle- and syringe-sharing. Administering HIV PEP in the prison setting is complicated by challenging risk assessment and follow-up.
