Antiretroviral treatment in correctional facilities

Operationalization of Status Neutral Human Immunodeficiency Virus Care for Criminal-Legal Involved Populations

The United States has the highest number of people incarcerated in the world. Criminal-legal involved populations, including people who are incarcerated in jails and prisons and people who are under community carceral control through probation or parole are at an increased risk for human immunodeficiency virus (HIV). Increasing access to HIV testing, treatment and prevention is necessary to curb the HIV epidemic. This chapter outlines the history of HIV testing in jails and prisons and suggests a Status Neutral HIV Care Framework for improving access to HIV prevention services.

Imprisonment for South Ethiopian people living with HIV presents a double health burden: lived experiences of prisoners

BACKGROUND

Optimal adherence is crucial for ensuring both therapeutic and preventative benefits of antiretroviral therapy (ART). Sub-optimal adherence is common in prisoners and little information is available about its predisposing circumstances in resource-limited settings. We explored lived experiences of inmates living with HIV (ILWH) and experiential accounts of service providers in South Ethiopia to identify barriers to and facilitators of HIV care use in the prison context.

METHODS

We conducted qualitative in-depth interviewing with eleven ILWH and eleven service providers. Audio recorded interview data were transcribed verbatim in Amharic language, translated into English and coded based on emerging concepts. We employed a descriptive phenomenological approach to abstract meaning attributed to the prisoners' lived experiences in relation to HIV care use and service providers' experiential account regarding care provision as presented to our consciousness.

FINDINGS

Several concepts emerged as barriers to HIV care use amongst ILWH in South Ethiopia including: limited access to standard care, insufficient health staff support, uncooperative security system, loss of patient privacy, a lack of status disclosure due to social stigma, and food supply insufficiency. In addition to a unique opportunity offered by an imprisonment for some ILWH to refrain from health damaging behaviours, the presence of social support in the prison system facilitated care use.

CONCLUSIONS

This study identified important structural and social contexts that can both hinder and enhance HIV care use amongst ILWH in South Ethiopia. Given the disproportionate burden of HIV in prisoners and the potential of transmission to others during and after incarceration, development of contextually-responsive strategies is required to address the barriers and to also strengthen the enablers.

A systematic review and meta-analyses on initiation, adherence and outcomes of antiretroviral therapy in incarcerated people

BACKGROUND

Incarcerated people are at increased risk of human immunodeficiency virus (HIV) infection relative to the general population. Despite a high burden of infection, HIV care use among prison populations is often suboptimal and varies among settings, and little evidence exists explaining the discrepancy. Therefore, this review assessed barriers to optimal use of HIV care cascade in incarcerated people.

METHODS

Quantitative and qualitative studies investigating factors affecting linkage to care, ART (antiretroviral therapy) initiation, adherence and/or outcomes among inmates were systematically searched across seven databases. Studies published in English language and indexed up to 26 October 2018 were reviewed. We performed a narrative review for both quantitative and qualitative studies, and meta-analyses on selected quantitative studies. All retrieved quantitative studies were assessed for risk of bias. Meta-analyses were conducted using RevMan-5 software and pooled odds ratios were calculated using Mantel-Haenszel statistics with 95% confidence interval at a p<0.05. The review protocol has been published at the International Prospective Register of Systematic Reviews (PROSPERO; Number: CRD42019135502).

RESULTS

Of forty-two studies included in the narrative review, eight were qualitative studies. Sixteen of the quantitative studies were eligible for meta-analyses. The narrative synthesis revealed structural factors such as: a lack of access to community standard of HIV care, particularly in resource limited countries; loss of privacy; and history of incarceration and re-incarceration as risk factors for poor HIV care use in prison populations. Among social and personal characteristics, lack of social support, stigma, discrimination, substance use, having limited knowledge about, and negative perception towards ART were the main determinants of suboptimal use of care in incarcerated people. In the meta-analyses, lower odds of ART initiation was noticed among inmates with higher baseline CD4 count (CD4 ≥500celss/mm3) (OR = 0.37, 95%CI: 0.14-0.97, I2 = 43%), new HIV diagnosis (OR = 0.07, 95%CI: 0.05-0.10, I2 = 68%), and in those who lacked belief in ART safety (OR = 0.32, 95%CI: 0.18-0.56, I2 = 0%) and efficacy (OR = 0.31, 95%CI: 0.17-0.57, I2 = 0%). Non-adherence was high among inmates who lacked social support (OR = 3.36, 95%CI: 2.03-5.56, I2 = 35%), had low self-efficiency score (OR = 2.50, 95%CI: 1.64,-3.80, I2 = 22%) and those with depressive symptoms (OR = 2.02, 95%CI: 1.34-3.02, I2 = 0%). Lower odds of viral suppression was associated with history of incarceration (OR = 0.40, 95%CI: 0.35-0.46, I2 = 0%), re-incarceration (OR = 0.09, 95%CI: 0.06-0.13, I2 = 64%) and male gender (OR = 0.55, 95%CI: 0.42-0.72, I2 = 0%). Higher odds of CD4 count <200cells/mm3 (OR = 2.01, 95%CI: 1.62, 2.50, I2 = 44%) and lower odds of viral suppression (OR = 0.20, 95%CI: 0.17-0.22, I2 = 0%) were observed during prison entry compared to those noticed during release.

CONCLUSION

Given the high HIV risk in prison populations and rapid movements of these people between prison and community, correctional facilities have the potential to substantially contribute to the use of HIV treatment as a prevention strategy. Thus, there is an urgent need for reviewing context specific interventions and ensuring standard of HIV care in prisons, particularly in resource limited countries.

"It's like I was out there by myself": The receipt of reentry support among HIV-infected formerly incarcerated individuals in New York City

BACKGROUND

In the U.S., approximately one in seven HIV-infected individuals experience incarceration at least once in their lifetime. While HIV-infected individuals experience positive health outcomes during periods of incarceration, they tend to experience treatment disruption as they return to their community after custody which results in poor health outcomes. The purpose of this study was to explore the transitional support received from the Department of Corrections during the reentry period.

METHODS

We conducted in-depth interviews with 20 HIV-infected formerly incarcerated individuals in New York City. Interviews were audio recorded and transcribed. Three researchers performed line-by-line reading of the transcripts to identify dominant codes and themes that emerged. A mixture of deductive and inductive techniques was used to identify patterns that emerged in the data.

RESULTS

Most of the participants were male and racial and ethnic minorities. There were five dominant themes that emerged during our analysis: 1) variations in the quantity of antiretroviral medication received during transition; 2) linkages to community-based physical health care providers was not well-coordinated; 3) insufficient housing and social resources; 4) structural and social challenges to post-release well-being; and 5) family as a source of resilience.

CONCLUSIONS

Discharge support planning should include sufficient medication to prevent treatment disruption and a more comprehensive approach to linkage to community-based healthcare services. Such planning should also include thorough pre-release assessments to identify appropriate levels of support needed, including employment and housing assistance, which will be useful for resource allocation. Broadening public health partnerships may also increase availability and promote accessibility to the most appropriate healthcare services and programs, which may provide better opportunities to receive coordinated care and ensure continuity of care. Finally, ties to family members and other loved ones should be leveraged to help facilitate the achievement of optimal health outcomes among this population.

Hospitalization Among HIV-Infected U.S. Marshals Service Prisoners

The U.S. Marshals Service (USMS) prisoner population is diverse and includes immigration violators, fugitives that have evaded apprehension, perpetrators of Medicaid fraud, and parole and probation violators. Unlike state and local jails, the USMS has numerous housing options for its prisoners. Given the unique characteristics, federal prisoners' quality of care, and subsequent clinical outcomes, may differ from those of state and local inmates. However, little is known about hospitalization rates and length of stay for HIV-positive USMS prisoners. The purpose of this study is to examine hospitalizations among HIV-infected prisoners in the custody of the USMS.

Adherence to antiretroviral therapy among HIV-infected prisoners: a systematic review and meta-analysis

Data on antiretroviral therapy (ART) adherence among prison inmates are limited and not previously synthesized in a systematic manner. The objective of this study was to provide accurate and up-to-date ART adherence estimates among prison inmates. We searched electronic databases for all studies reporting adherence as a primary or secondary outcome among prison inmates. A random-effects model was used to pool adherence rates; sensitivity, heterogeneity and publication bias were assessed. Eleven studies involving 2895 HIV-infected prison inmates were included. The studies were carried out between 1992 and 2011 and reported between 1998 and 2013. A pooled analysis of all studies indicated a pooled estimate of 54.6% (95% confidence interval 48.1-60.9%) of prison inmates had adequate (≥95%) ART adherence. The adherence estimates were significantly higher among cross-studies and studies that used self-reported measures. In summary, our findings indicate that optimal adherence remains a challenge among prison inmates. It is crucial to monitor ART adherence and develop appropriate interventions to improve adherence among these population.

HIV treatment and care among Italian inmates: a one-month point survey

Background

HIV infection, with an estimated prevalence be between 2 and 50 times those of the general adult population is a major health challenge for prison authorities worldwide. Since no nationwide surveillance system is present in Italy, data on HIV prevalence and treatment in prisons are limited to only a few and small observational studies. We aimed to estimate HIV prevalence and obtain an overview on diagnostic and therapeutic activities concerning HIV infection in the Italian penitentiary system.

Methods

We piloted a multi-centre cross-sectional study investigating the prevalence of HIV infection and assessing HIV-related medical activities in Italian correctional institutions.

Results

A total of 15,675 prisoners from 25 institutions, accounting for approximately one-fourth of the prison inmates in Italy, were included in the study, of whom, 97.7 % were males, 37.1 % foreigners and 27 % had a history of intravenous drug addiction. HIV-tests were available in 42.3 % of the total population, with a known HIV Infection proportion of 5.1 %. In the month prior to the study, 604 of the 1,764 subjects who entered prison were tested for HIV, with a HIV-positive prevalence of 3.3 %. Among the 338 HIV-positive prisoners, 81.4 % were under antiretroviral treatment and 73.5 % showed undetectable HIV-RNA. In 23/338 (6.8 %) a coinfection with HBV and in 189/338 (55.9 %) with HCV was also present. Among the 67 (19.8 %) inmates with HIV who did not receive HIV treatment, 13 (19.5 %) had T-CD4+ count <350 cells/mm³ and 9 (69.2 %) of these had refused the treatment. The majority of the inmates with HIV-infection were on a PI-based (62.5 %) or on NNRTIs-based (24.4 %) regimen. Only a minority of patients received once daily regimens (17.2 %).

Conclusions

Although clinical and therapeutic management of HIV infection remains difficult in Italian prisons, diagnostics, treatment and care were offered to the majority of HIV-infected inmates. Specific programs should be directed towards the prison population and strict cooperation between prison and health institutions is needed to increase HIV treatment.

Outcomes of on-site antiretroviral therapy provision in a South African correctional facility

We evaluated a novel on-site antiretroviral therapy (ART) programme in a South African correctional facility using routinely collected programme data, from a retrospective cohort of adult inmates starting ART between 03/2007 and 03/2009 followed-up to 09/2009. We report (1) mortality (using survival analysis); (2) retention in the programme (to 09/2009); and (3) virological suppression at six and 12 months (<400 copies/ml) following ART initiation. In total, 404 started ART (median age 33 years; 91.3% men; median baseline CD4 cell count 152 cells/µl [interquartile range 85-225]). Among 299 starting ART for the first time (ART-naïve), 23 deaths occurred during 252 person-years (median follow-up nine months). Mortality rates were 17.2 at 0-6 months (95% confidence interval 10.9-26.9) and 2.8 at >6 months (95% confidence interval 1.1-7.5)/100 person-years; p < 0.001. At 09/2009, 35.6% (144/404) remained in the correctional facility, with 94.4% (136/144) retained in the programme; 38.4% (155/404) were released; and 20.0% (81/404) transferred to another facility. ART-naïve patients in care six and 12 months after ART initiation, 94.7% (124/131) and 92.5% (74/80) were virologically suppressed, respectively. High early mortality warrants the early identification and management of HIV-positive inmates. The high mobility of inmates necessitates systems for facilitating continuity of care. Good virological responses and retention supports decentralising HIV care to correctional facilities.

What we know and what we do not know about factors associated with and interventions to promote antiretroviral adherence

Antiretroviral therapy (ART) adherence remains critical for achieving successful outcomes. Factors affecting ART adherence can occur at the individual level or be related to the treatment regimen, daily schedule, and/or interpersonal relationships. While treatment-related barriers have diminished with recent simplified ART regimens, guidelines still recommend considering regimen simplicity. ART readiness should be assessed prior to starting ART, with follow-up adherence assessments once ART is initiated, and at all subsequent clinical visits. Adherence interventions work best when multifaceted, targeted for at-risk and nonadherent participants, and tailored to individuals' needs. Successful interventions have included education and counseling, provision of social support, directly observed therapy, and financial incentives. Pillboxes and two-way short-text messaging service (SMS) reminders have been shown to be effective and are widely recommended tools for promoting ART adherence. Further research is needed to determine the optimal combination of adherence interventions, as well as generalizability, implementation, and cost-effectiveness.

Effect of directly observed antiretroviral therapy compared to self-administered antiretroviral therapy on adherence and virological outcomes among HIV-infected prisoners: a randomized controlled pilot study

The effect of directly observed therapy (DOT) versus self-administered therapy (SAT) on antiretroviral (ART) adherence and virological outcomes in prison has never been assessed in a randomized, controlled trial. Prisoners were randomized to receive ART by DOT or SAT. The primary outcome was medication adherence [percent of ART doses measured by the medication event monitoring system (MEMS) and pill counts] at the end of 24 weeks. The changes in the plasma viral loads from baseline and proportion of participants virological suppressed (<400 copies/mL) at the end of 24 weeks were assessed. Sixty-six percent (90/136) of eligible prisoners declined participation. Participants in the DOT arm (n = 20) had higher viral loads than participants in the SAT (n = 23) arm (p = 0.23). Participants, with complete data at 24 weeks, were analyzed as randomized. There were no significant differences in median ART adherence between the DOT (n = 16, 99% MEMS [IQR 93.9, 100], 97.1 % pill count [IQR 95.1, 99.3]) and SAT (n = 21, 98.3 % MEMS [IQR 96.0, 100], 98.5 % pill count [95.8, 100]) arms (p = 0.82 MEMS, p = 0.40 Pill Count) at 24 weeks. Participants in the DOT arm had a greater reduction in viral load of approximately -1 log 10 copies/mL [IQR -1.75, -0.05] compared to -0.05 [IQR -0.45, 0.51] in the SAT arm (p value = 0.02) at 24 weeks. The proportion of participants achieving virological suppression in the DOT vs SAT arms was not statistically different at 24 weeks (53 % vs 32 %, p = 0.21). These findings suggest that DOT ART programs in prison settings may not offer any additional benefit on adherence than SAT programs.

Namibian prisoners describe barriers to HIV antiretroviral therapy adherence

Little is available in scholarly literature about how HIV-positive prisoners, especially in low-income countries, access antiretroviral therapy (ART) medication. We interviewed 18 prisoners at a large prison in Namibia to identify barriers to medication adherence. The lead nurse researcher was a long-standing clinic employee at the prison, which afforded her access to the population. We identified six significant barriers to adherence, including (1) the desire for privacy and anonymity in a setting where HIV is strongly stigmatized; (2) the lack of simple supports for adherence, such as availability of clocks; (3) insufficient access to food to support the toll on the body of ingesting taxing ART medications; (4) commodification of ART medication; (5) the brutality and despair in the prison setting, generally leading to discouragement and a lack of motivation to strive for optimum health; and (6) the lack of understanding about HIV, how it is transmitted, and how it is best managed. Because most prisoners eventually transition back to communitysettings when their sentences are served, investments in prison health represent important investments in public health.

Violence and the perceived risks of taking antiretroviral therapy in US jails and prisons

PURPOSE

About one in five men living with HIV in the USA passes through a correctional center annually. Jails and prisons are seen therefore as key intervention sites to promote HIV treatment as prevention. Almost no research, however, has examined inmates' perspectives on HIV treatment or their strategies for retaining access to antiretroviral therapy (ART) during incarceration. The purpose of this paper is to describe the results of an exploratory study examining men's perceptions of and experiences with HIV care and ART during incarceration.

DESIGN/METHODOLOGY/APPROACH

Semi-structured, in-depth interviews were conducted with 42 HIV positive male and male-to-female transgendered persons recently released from male correctional centers in Illinois, USA.

FINDINGS

Interpersonal violence, a lack of safety, and perceived threats to privacy were frequently cited barriers to one's willingness and ability to access and adhere to treatment. Over 60 percent of study participants reported missed doses or sustained treatment interruption (greater than two weeks) because of failure to disclose their HIV status, delayed prescribing, intermittent dosing and out-of-stock medications, confiscation of medications, and medication strikes.

RESEARCH LIMITATIONS/IMPLICATIONS

Substantial improvements in ART access and adherence are likely to follow organizational changes that make incarcerated men feel safer, facilitate HIV status disclosure, and better protect the confidentiality of inmates receiving ART.

ORIGINALITY/VALUE

This study identified novel causes of ART non-adherence among prisoners and provides first-hand information about how violence, stigma, and the pursuit of social support influence prisoner's decisions to disclose their HIV status or accept ART during incarceration.

HIV among persons incarcerated in the USA: a review of evolving concepts in testing, treatment, and linkage to community care

PURPOSE OF REVIEW

People who are incarcerated have a disproportionately high risk of HIV infection. They also tend to have risk factors associated with underutilization of antiretroviral therapy (ART) such as substance abuse, mental illness, and poor access to care. In this review, we describe how incarceration is a marker of vulnerability for suboptimal HIV care, and also how criminal justice settings may be leveraged as a platform for promoting testing, linkage, and retention in HIV care for a high-risk, marginalized population.

RECENT FINDINGS

In both prisons and jails, routine, opt-out HIV testing strategies are more appropriate for screening correctional populations than traditional, risk-based strategies. Rapid HIV testing is feasible and acceptable in busy, urban jail settings. Although ART is successfully administered in many prison settings, release to the community is strongly associated with inconsistent access to medications and other structural factors leading to loss of viral suppression.

SUMMARY

Collaborations among HIV clinicians, criminal justice personnel, and public health practitioners represent an important strategy for turning the tide on the HIV epidemic. Success will depend upon scaled-up efforts to seek individuals with undiagnosed infection and bring those who are out-of-care into long-term treatment.

Directly observed versus self-administered antiretroviral therapies: preference of HIV-positive jailed inmates in San Francisco

Directly observed therapy (DOT) of antiretroviral (ARV) medications has beneficial effects on HIV treatment for incarcerated inmates but has been associated with limited continuation after release and inadvertent disclosure of HIV status. Guided self-administered therapy (g-SAT) may be a preferred method of ARV delivery and may encourage medication-taking behavior. We surveyed the preference of 102 HIV-positive jailed inmates at the San Francisco City and County Jails regarding receiving ARVs via DOT versus g-SAT while incarcerated. Participants overwhelmingly preferred g-SAT over DOT.

Guidelines for improving entry into and retention in care and antiretroviral adherence for persons with HIV: evidence-based recommendations from an International Association of Physicians in AIDS Care panel

DESCRIPTION

After HIV diagnosis, timely entry into HIV medical care and retention in that care are essential to the provision of effective antiretroviral therapy (ART). Adherence to ART is among the key determinants of successful HIV treatment outcome and is essential to minimize the emergence of drug resistance. The International Association of Physicians in AIDS Care convened a panel to develop evidence-based recommendations to optimize entry into and retention in care and ART adherence for people with HIV.

METHODS

A systematic literature search was conducted to produce an evidence base restricted to randomized, controlled trials and observational studies with comparators that had at least 1 measured biological or behavioral end point. A total of 325 studies met the criteria. Two reviewers independently extracted and coded data from each study using a standardized data extraction form. Panel members drafted recommendations based on the body of evidence for each method or intervention and then graded the overall quality of the body of evidence and the strength for each recommendation.

RECOMMENDATIONS

Recommendations are provided for monitoring entry into and retention in care, interventions to improve entry and retention, and monitoring of and interventions to improve ART adherence. Recommendations cover ART strategies, adherence tools, education and counseling, and health system and service delivery interventions. In addition, they cover specific issues pertaining to pregnant women, incarcerated individuals, homeless and marginally housed individuals, and children and adolescents, as well as substance use and mental health disorders. Recommendations for future research in all areas are also provided.

Antiretroviral outcomes in South African prisoners: a retrospective cohort analysis

BACKGROUND AND METHODS

Little is known about antiretroviral therapy (ART) outcomes in prisoners in Africa. We conducted a retrospective review of outcomes of a large cohort of prisoners referred to a public sector, urban HIV clinic. The review included baseline characteristics, sequential CD4 cell counts and viral load results, complications and co-morbidities, mortality and loss to follow-up up to 96 weeks on ART.

FINDINGS

148 inmates (133 male) initiated on ART were included in the study. By week 96 on ART, 73% of all inmates enrolled in the study and 92% of those still accessing care had an undetectable viral load (<400 copies/ml). The median CD4 cell count increased from 122 cells/mm(3) at baseline to 356 cells/mm(3) by 96 weeks. By study end, 96 (65%) inmates had ever received tuberculosis (TB) therapy with 63 (43%) receiving therapy during the study: 28% had a history of TB prior to ART initiation, 33% were on TB therapy at ART initiation and 22% developed TB whilst on ART. Nine (6%) inmates died, 7 in the second year on ART. Loss to follow-up (LTF) was common: 14 (9%) patients were LTF whilst still incarcerated, 11 (7%) were LTF post-release and 9 (6%) whose movements could not be traced. 16 (11%) inmates had inter-correctional facility transfers and 34 (23%) were released of whom only 23 (68%) returned to the ART clinic for ongoing follow-up.

CONCLUSIONS

Inmates responded well to ART, despite a high frequency of TB/HIV co-infection. Attention should be directed towards ensuring eligible prisoners access ART programs promptly and that inter-facility transfers and release procedures facilitate continuity of care. Institutional TB control measures should remain a priority.

HIV and incarceration: prisons and detention

The high prevalence of HIV infection among prisoners and pre-trial detainees, combined with overcrowding and sub-standard living conditions sometimes amounting to inhuman or degrading treatment in violation of international law, make prisons and other detention centres a high risk environment for the transmission of HIV. Ultimately, this contributes to HIV epidemics in the communities to which prisoners return upon their release. We reviewed the evidence regarding HIV prevalence, risk behaviours and transmission in prisons. We also reviewed evidence of the effectiveness of interventions and approaches to reduce the risk behaviours and, consequently, HIV transmission in prisons. A large number of studies report high levels of risk behaviour in prisons, and HIV transmission has been documented. There is a large body of evidence from countries around the world of what prison systems can do to prevent HIV transmission. In particular, condom distribution programmes, accompanied by measures to prevent the occurrence of rape and other forms of non-consensual sex, needle and syringe programmes and opioid substitution therapies, have proven effective at reducing HIV risk behaviours in a wide range of prison environments without resulting in negative consequences for the health of prison staff or prisoners.The introduction of these programmes in prisons is therefore warranted as part of comprehensive programmes to address HIV in prisons, including HIV education, voluntary HIV testing and counselling, and provision of antiretroviral treatment for HIV-positive prisoners. In addition, however, action to reduce overcrowding and improve conditions in detention is urgently needed.

Opportunities to diagnose, treat, and prevent HIV in the criminal justice system

Persons involved with the criminal justice system are at risk for HIV and other transmissible diseases due to substance use and related risk behaviors. Incarceration provides a public health opportunity to test for HIV, viral hepatitis, and other sexually transmitted infections, provide treatment such as highly active antiretroviral therapy, and link infected persons to longitudinal comprehensive HIV care upon their release for such comorbidities as addiction and mental illness. Delivering health interventions inside prisons and jails can be challenging, yet the challenges pale in comparison to the benefits of interventions for inmates and their communities. This article reviews the current state of delivering HIV testing, prevention, treatment, and transition services to incarcerated populations in the United States. It concludes with summary recommendations for research and practice to improve the health of inmates and their communities.

HIV testing and treatment with correctional populations: people, not prisoners

Institutional policies, practices, and norms can impede the delivery of ethical standard-of-care treatment for people with HIV in correctional settings. In this commentary, we focus on the fundamental issues that must be addressed to create an ethical environment in which best medical practices can be implemented when working with correctional populations. Thus, we consider ethical issues related to access to services, patient privacy, confidentiality, informed consent for testing and treatment, and issues related to the provision of services in an institutional setting in which maintenance of security is the primary mission. Medical providers must understand and navigate the dehumanization inherent in most correctional settings, competing life demands for incarcerated individuals, power dynamics within the correctional system, and the needs of family and significant others who remain in the community.

People who use drugs, HIV, and human rights

We reviewed evidence from more than 900 studies and reports on the link between human rights abuses experienced by people who use drugs and vulnerability to HIV infection and access to services. Published work documents widespread abuses of human rights, which increase vulnerability to HIV infection and negatively affect delivery of HIV programmes. These abuses include denial of harm-reduction services, discriminatory access to antiretroviral therapy, abusive law enforcement practices, and coercion in the guise of treatment for drug dependence. Protection of the human rights of people who use drugs therefore is important not only because their rights must be respected, protected, and fulfilled, but also because it is an essential precondition to improving the health of people who use drugs. Rights-based responses to HIV and drug use have had good outcomes where they have been implemented, and they should be replicated in other countries.

The impact of incarceration upon adherence to HIV treatment among HIV-positive injection drug users: a qualitative study

INTRODUCTION

HIV-positive injection drug users (IDU) often do not derive the full benefits of highly active antiretroviral therapy (HAART). Among IDU, recent incarceration has been associated with discontinuation of HAART for non-clinical reasons. We sought to qualitatively evaluate experiences with HAART among HIV-positive IDU who had been recently incarcerated within provincial prisons in British Columbia in order to identify factors influencing adherence to treatment.

METHODS

Twelve in-depth qualitative interviews were conducted with males recruited from a cohort study (ACCESS) involving over 450 HIV-positive IDU. All participants had been incarcerated after initiating HAART. Audio-recorded interviews were conducted to examine experiences of taking HAART in prison, with particular attention to adherence and experiences of treatment discontinuation.

FINDINGS

Participant accounts described situations where adherence to HIV treatment was compromised in custody. A small number of participants reported treatment interruptions that lasted over a week when they were unable to obtain HIV medications through institutional healthcare. Short-term interruptions in treatment were said to be common during intake into the correctional system and at the point of release from custody. High levels of HIV discrimination motivate prisoners to hide the fact that they are HIV-positive by making efforts to take medications discreetly, which may result in missed doses.

CONCLUSIONS

The current study identified contextual factors within correctional environments that hinder individuals' ability to adhere to HAART. These findings also indicate that improved health services and coordination with community care providers are needed to enhance the quality of HIV treatment within correctional environments.

The impact of antiretroviral therapy in a cohort of HIV infected patients going in and out of the San Francisco county jail

Background

Jails are an important venue of HIV care and a place for identification, treatment and referral for care. HIV infected inmates in the San Francisco County jail are offered antiretroviral treatment (ART), which many take only while in jail. We evaluated the effect of ART administration in a cohort of jail inmates going in and out of jail over a nine year period.

Methodology/Principal Findings

In this retrospective study, we examined inmates with HIV going in and out of jail. Inmates were categorized by patterns of ART use: continuous ART - ART both in and out of jail, intermittent ART - ART only in jail; never on ART - eligible by national guidelines, but refused ART. CD4 and HIV viral load (VL) were compared over time in these groups. Over a 9 year period, 512 inmates were studied: 388 (76%) on intermittent ART, 79 (15%) on continuous ART and 45(9%) never-on ART. In a linear mixed model analysis, inmates on intermittent ART were 1.43; 95%CI (1.03, 1.99) times and those never on ART were 2.89; 95%CI (1.71, 4.87) times more likely to have higher VL than inmates on continuous ART. Furthermore, Inmates on intermittent ART and never-on ART lost 1.60; 95%CI (1.06, 2.13) and 1.97; 95%CI (0.96, 3.00) more CD4 cells per month, respectively, compared to continuously treated inmates. The continuous ART inmates gained 0.67CD4 cells/month.

Conclusions/Significance

Continuous ART therapy in jail inmate's benefits CD4 cell counts and control of VL especially compared to those who never took ART. Although jail inmates on intermittent ART were more likely to lose CD4 cells and experience higher VL over time than those on continuous ART, CD4 cell loss was slower in these inmates as compared to inmates never on ART. Further studies are needed to evaluate whether or not intermittent ART provides some benefit in outcome if continuous ART is not possible or likely.

Early immunologic and virologic responses to highly active antiretroviral therapy and subsequent disease progression among HIV-infected injection drug users

We examined the prevalence and prognostic value of early responses to highly active antiretroviral therapy (HAART) among community-based injection drug users (IDUs) in Baltimore. Virologic (HIV RNA <1000 copies/ml) and immunologic (CD4 >500 cells/ul or increase of 50 cells/ul from the pre-HAART level) responses were examined in the 1st year of HAART initiation. Cox regression was used to examine the effect of early response on progression to new AIDS diagnosis or AIDS-related death. Among 258 HAART initiators, 75(29%) had no response, 53(21%) had a virologic response only, 38(15%) had an immunologic response only and 92(36%) had a combined immunologic and virologic response in the first year of therapy. Poorer responses were observed in those who were older, had been recently incarcerated, reported injecting drugs, had not had a recent outpatient visit and had some treatment interruption within the 1st year of HAART. In multiple Cox regression analysis, the risk of progression was lower in those with combined virologic and immunologic response than in non-responders, (relative hazard [RH], 0.32; 95% confidence interval [CI], 0.17-0.60). Those with discordant responses had reduced risk of progression compared to non-responders but experienced faster progression than those with a combined response, although none of these differences was statistically significant. Early discordant and non response to HAART was common, often occurred in the setting of injection drug use and treatment interruption and was associated with poorer survival. Interventions to reduce treatment interruptions and to provide continuity of HIV care during incarceration among IDUs are needed to improve responses and subsequent survival.

HIV-related issues and concerns for imprisoned persons throughout the world

PURPOSE OF REVIEW

To summarize articles related to HIV/AIDS and correctional populations that were published from January 2004 through March 2005. In all, 43 empirical and seven non-empirical articles are summarized, about two-thirds of which are focused on correctional populations in the USA. The majority of the studies were descriptive; only two articles presented evaluation data for HIV prevention interventions.

RECENT FINDINGS

Published studies during the review period documented elevated rates of HIV, STIs, and hepatitis among correctional populations--often associated with injection drug use, mental illness, and infectious-disease co-morbidity. These studies highlighted a global public-health need for comprehensive HIV risk-reduction programs that address not only disease prevention but also the factors enabling disease transmission. Research further demonstrated the detrimental effects of release from prison on medication adherence and disease progression among HIV-positive people, underscoring the need for transitional treatment and health-care services.

SUMMARY

HIV-related research is urgently needed to document the global scope of HIV disease prevalence and correlates among incarcerated populations, to examine the impact of incarceration and release from prison on HIV risk behavior, to identify optimal treatment programs for HIV-positive individuals, and to rigorously evaluate HIV risk-reduction interventions for incarcerated people--particularly those focused on the period of community re-entry. Finally, research and activism are needed to impact structural factors impeding HIV-prevention efforts with correctional populations.
