HCV infected prisoners: should they be still considered a difficult to treat population?

The effect of direct-acting antiviral regimens and telemedicine on the treatment of inmates with hepatitis C virus infection in Israeli prisons

BACKGROUND

Direct-acting antiviral (DAA) regimens and telemedicine services are both options for treating hepatitis C virus (HCV) within the prison setting. We aimed to compare factors associated with HCV treatment success over the past decade in Israeli prisons, specifically the influence of DAAs and telemedicine.

METHODS

We retrospectively reviewed the medical records of inmates with HCV infection in Israeli prisons from 2010 through 2020. Demographic, clinical, and laboratory data were recorded, including treatment regimens and success rates.

RESULTS

A total of 273 inmates were treated; mean age 45 ± 9.36 years; 98.2% males; 63.9% with a history of drug abuse. Advanced fibrosis was documented in 42.9%. The most common genotypes were 1 (46%) followed by 3 (40.7%). Interferon-based regimens were given to 68 inmates between 2010 and 2017. DAA agents were introduced in 2016, with pan-genotype regimens being exclusively used since 2019. Telemedicine services were used in 140 patients (51.3%), starting in February 2019. The sustained viral response (SVR) rate with interferon-based therapy was 78.8% and 98.8% with DAA treatment, giving an overall SVR of 93.2%. This difference between regimens proved to be the only statistically significant predictor of treatment success. The number of prisoners being treated with DAAs increased exponentially after telemedicine was introduced. Comparable SVR rates were achieved with either in-person or telemedicine consultation.

CONCLUSION

Screening of this high-risk population and using telemedicine for treatment may be an effective strategy for the elimination of HCV from the prison population.

The impact of unrestricted access to direct-acting antiviral among incarcerated hepatitis C virus-infected patients

Background/Aims

Despite the disproportionally high prevalence rates of hepatitis C virus (HCV) amongst the incarcerated population, eradication remains challenging due to logistic and financial barriers. Although treatment prioritization based on disease severity is commonly practiced, the efficacy of such approach remained uncertain. We aimed to compare the impact of unrestricted access to direct-acting antiviral (DAA) among incarcerated HCV-infected patients in Singapore.

Methods

In this retrospective study, we reviewed all incarcerated HCV-infected patients treated in our hospital during the restricted DAA era (2013–2018) and unrestricted DAA access era (2019). Study outcomes included the rate of sustained virological response (SVR), treatment completion and treatment default. Subgroup analysis was performed based on the presence of liver cirrhosis, HCV genotype and HCV treatment types.

Results

A total of 1,001 HCV patients was followed-up for 1,489 person-year. They were predominantly male (93%) with genotype-3 HCV infection (71%), and 38% were cirrhotic. The overall SVR during the restricted DAA access era and unrestricted DAA access era were 92.1% and 99.1%, respectively. Unrestricted access to DAA exponentially improved the treatment access among HCV-infected patients by 460%, resulting in a higher SVR rate (99% vs. 92%, P=0.003), higher treatment completion rate (99% vs. 93%, P<0.001) and lower treatment default rate (1% vs. 9%, P<0.001).Conclusion: In this large cohort of incarcerated HCV-infected patients, we demonstrated that unrestricted access to DAA is an impactful strategy to allow rapid treatment up-scale in HCV micro-elimination.

Prevalence of Drug Injection, Sexual Activity, Tattooing, and Piercing Among Prison Inmates

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.

A systematic review on models of care effectiveness and barriers to Hepatitis C treatment in prison settings in the EU/EEA

Hepatitis C prevalence in prison populations is much higher than in the community. Effective hepatitis C treatment within this population does not only have a direct individual health benefit, but may lead to substantial community dividend. We reviewed available evidence on hepatitis C treatment in prison settings, with a focus on the European Union/European Economic Area. A systematic review of the literature (PubMed, EMBASE, Cochrane library) was performed and complemented with searches for conference abstracts and grey literature. Thirty-four publications were included reporting on the effectiveness, acceptability and economic aspects of hepatitis C virus treatment models of care to achieve treatment completion and sustained viral response in prison settings. Available evidence shows that hepatitis C treatment in prison settings is feasible and the introduction of direct-acting antivirals will most likely result in increased treatment completion and better clinical outcomes for the prison population, given the caveats of affordability and the need for increased funding for prison health, with the resulting benefits accruing mostly in the community.

Evaluation of cost-effectiveness of peginterferon plus ribavirin for chronic hepatitis C treatment and direct-acting antiviral agents among HIV-infected patients in the prison and community settings

BACKGROUND

In Taiwan, the majority of chronic hepatitis C carriers with HIV co-infection are intravenous drug users and inmates in correctional facilities. Peginterferon and ribavirin (PegIFN/RBV) have been the standard-of-care for chronic hepatitis C virus (HCV) infection more than decades. We evaluated the estimated cost-effectiveness of PegIFN/RBV from the National Health Insurance Research Database, covering the population of Taiwan from 1998 to 2013.

MATERIALS AND METHODS

This is an observational study, and study during was 2010-2016 and a total of 239 patients were treated with PegIFN/RBV. Of them, 156 patients were treated in the correctional facilities of Taipei, Taoyuan, Taichung and Taitung prisons, and 83 patients were treated in communities. The cost-effectiveness was analyzed in regimens of PegIFN/RBV and direct-acting antiviral agents.

RESULTS

By multivariate analysis, the patients completed PegIFN/RBV in prison (adjusted odds ratio [aOR]: 4.56, 95% confidence interval [CI]: 1.58-13.12, p = 0.005), HCV RNA level <800,000 IU/mL (aOR: 4.0, 95% CI: 1.27-12.66, p = 0.02) at baseline, and the presence of early virologic response (EVR) (aOR: 7.67, 95% CI: 1.89-31.06, p = 0.004) were independent predictors for sustained virologic response (SVR). For the subgroups of prisoners, HIV-infected prisoners and HIV-infected patients in communities, the SVR rate was 73.8%, 72.0% and 36.8%, and the average medical-care cost was US$7,701, $7,893, and $15,443 per SVR achieved, respectively. Also, the estimated medical-care cost for genotype 6 was US$9211.

CONCLUSIONS

Chronic HCV/HIV co-infected patients with genotype 1 and 6 in the community setting could benefit from DAAs in Taiwan.

Six-Month Emergency Department Use among Older Adults Following Jail Incarceration

Although the number of older adults who are arrested and subject to incarceration in jail is rising dramatically, little is known about their emergency department (ED) use or the factors associated with that use. This lack of knowledge impairs the ability to design evidence-based approaches to care that would meet the needs of this population. This 6-month longitudinal study aimed to determine the frequency of 6-month ED use among 101 adults aged 55 or older enrolled while in jail and to identify factors associated with that use. The primary outcome was self-reported emergency department use within 6 months from baseline. Additional measures included baseline socio-demographics, physical and mental health conditions, geriatric factors (e.g., recent falls, incontinence, functional impairment, concern about post-release safety), symptoms (pain and other symptoms), and behavioral and social health risk factors (e.g., substance use disorders, recent homelessness). Chi-square tests were used to identify baseline factors associated with ED use over 6 months. Participants (average age 60) reported high rates of multimorbidity (61%), functional impairment (57%), pain (52%), serious mental illness (44%), recent homelessness (54%), and/or substance use disorders (69%). At 6 months, 46% had visited the ED at least once; 21% visited multiple times. Factors associated with ED use included multimorbidity (p = 0.01), functional impairment (p = 0.02), hepatitis C infection (p = 0.01), a recent fall (p = 0.03), pain (p < 0.001), loneliness (p = 0.04), and safety concerns (p = 0.01). In this population of older adults in a county jail, geriatric conditions and distressing symptoms were common and associated with 6-month community ED use. Jail is an important setting to develop geriatric care paradigms aimed at addressing comorbid medical, functional, and behavioral health needs and symptomatology in an effort to improve care and decrease ED use in the growing population of criminal justice-involved older adults.

Treatment with direct-acting antivirals in a multicenter cohort of HCV-infected inmates in Italy

BACKGROUND

People who are incarcerated have a significantly higher prevalence of HCV infection than the general population. Given their high-risk behavior, they represent a reservoir of HCV infection for the whole community.

METHODS

We evaluated all HCV-infected people who were incarcerated in 25 Italian prisons starting direct-acting antivirals (DAAs) treatment between May 2015 and October 2016. We collected information on demographic characteristics, liver disease, HCV-related aspects, anti-HCV treatment, HIV or HBV co-infection.

RESULTS

We enrolled 142 incarcerated people treated with DAAs. They were mostly Italians (93.7%) and males (98.6%). Median age was 50 years and 108/142 (76.1%) were cirrhotic patients. Prevalent genotypes were 1a (35.9%) and 3 (35.9%). Two patients were HBV co-infected, twenty-one patients (14.8%) were HIV co-infected and almost all (95.2%) received antiretroviral therapy. 118/142 (83.1%) DAAs-based regimens included sofosbuvir. Treatment completion rate was 94.4%. There were eight (5.6%) discontinuations, one (0.7%) due to an adverse reaction, one due to death (0.7%) and six (5.6%) due to release from prison. SVR12 was achieved in 90.8%. Four patients relapsed but no breakthrough occurred.

CONCLUSIONS

Our study shows that in Italian penitentiary settings DAAs treatment is feasible and effective. This intervention is crucial for reducing HCV circulation with possible benefits to the general population.

HIV and hepatitis C virus infections in Quebec's provincial detention centres: comparing prevalence and related risky behaviours between 2003 and 2014-2015

OBJECTIVES

To compare the prevalence of HIV, hepatitis C virus (HCV) infections, and related risky behaviours among inmates in Quebec's provincial prisons between 2003 and 2014-2015.

METHODS

Cross-sectional data were anonymously collected from May 2014 to March 2015 for men (n = 1315) and women (n = 250) and combined with data collected in 2003 to evaluate trends in the last decade. Participants completed a questionnaire and provided saliva samples. The data from the 2003 and 2014-2015 surveys were merged for statistical analysis.

RESULTS

HIV prevalence was stable between 2003 and 2014-2015 for men (2.4% vs. 1.8%, p = 0.4), whereas it decreased for women (8.8% vs. 0.8%, p < 0.001). HCV prevalence decreased between 2003 and 2014-2015 for both men (16.6% vs. 11.9%, p < 0.001) and women (29.2% vs. 19.2%, p = 0.02). HIV and HCV prevalence were higher among people who inject drugs (PWID), for both sexes and both studies. PWID-specific prevalence did not change between 2003 and 2014-2015, except for a decrease in HIV prevalence in PWID women. However, the proportion of prisoners reporting a history of injection drug use outside prison was lower in 2014-2015 than in 2003 for men (19.8% vs. 27.7%, p < 0.0001) and women (28.6% vs. 42.6%, p = 0.002).

CONCLUSION

The lower proportion of PWID inmates in 2014-2015 compared to 2003 explained in large part the decrease in HIV and HCV prevalence. Despite the decrease in prevalence, HIV and HCV infections among incarcerated individuals still represent a major public health problem due to the sizable increase of individuals in Quebec's correctional system over the same period.

Genotype distribution and treatment response among incarcerated drug-dependent patients with chronic hepatitis C infection

The prevalence of hepatitis C virus (HCV) infection is disproportionately high among prisoners, especially among those who are drug-dependent. However, current screening and treatment recommendations are inconsistent for this population, and appropriate care is not reliably provided. To address these problems, the present study aimed to identify unique characteristics and clinical manifestations of incarcerated patients with HCV infection. We included incarcerated patients who received treatment with pegylated-interferon combined with ribavirin at Mackay Memorial Hospital in Taitung and were serving sentences at either the Taiyuan Skill Training Institute or the Yanwan Training Institute. HCV genotypes 1 (41.4%), 3 (25.9%), and 6 (24.1%) were the most prevalent in the incarcerated patients. During the study period, we analyzed treatment response among 58 incarcerated patients and compared obtained results with treatment response among 52 patients who were living in the community. Higher sustained virological response rate was observed among patients with incarceration and HCV genotype other than 1. The odds ratios (corresponding 95% confidence intervals) for incarceration and genotype 1 were 2.75 (1.06–7.11) and 0.37 (0.14–0.99), respectively. Better treatment compliance among incarcerated patients might partially explain these results. The results of this study suggest that treatment of prisoners with HCV infection is feasible and effective. More appropriate and timely methods are needed to prevent HCV transmission among injection drug users inside prisons.

HIV, prisoners, and human rights

Worldwide, a disproportionate burden of HIV, tuberculosis, and hepatitis is present among current and former prisoners. This problem results from laws, policies, and policing practices that unjustly and discriminatorily detain individuals and fail to ensure continuity of prevention, care, and treatment upon detention, throughout imprisonment, and upon release. These government actions, and the failure to ensure humane prison conditions, constitute violations of human rights to be free of discrimination and cruel and inhuman treatment, to due process of law, and to health. Although interventions to prevent and treat HIV, tuberculosis, hepatitis, and drug dependence have proven successful in prisons and are required by international law, they commonly are not available. Prison health services are often not governed by ministries responsible for national public health programmes, and prison officials are often unwilling to implement effective prevention measures such as needle exchange, condom distribution, and opioid substitution therapy in custodial settings, often based on mistaken ideas about their incompatibility with prison security. In nearly all countries, prisoners face stigma and social marginalisation upon release and frequently are unable to access health and social support services. Reforms in criminal law, policing practices, and justice systems to reduce imprisonment, reforms in the organisation and management of prisons and their health services, and greater investment of resources are needed.

Personality disorders do not affect treatment outcomes for chronic HCV infection in Spanish prisoners: the Perseo study

Background

The link between infection with hepatitis C virus (HCV) and personality disorders (PD) has not been investigated in detail. The aim of this study was to compare the effectiveness of HCV treatment in prisoners with and without PD.

Methods

We performed a prospective multicentre study in inmates from 25 Spanish prisons who had been treated with pegylated interferon alfa-2a plus ribavirin in 2011. PD diagnosis was based on the Personality Diagnostic Questionnaire-4+. We calculated adjusted Odds Ratios (AOR) and 95 % confidence intervals (95 % CI) using logistic regression.

Results

The sample included 236 patients (mean age: 40.3 years, 92.8 % male, 79.2 % intravenous drug users, and 26.3 % HIV-coinfected). The prevalence of PD was 72.5 %. 32.2 % of patients discontinued treatment; this percentage was higher in patients with HCV genotypes 1/4 (AOR = 3.55; CI:1.76–7.18) and those without PD (AOR = 2.51; 1.23–5.11). Treatment discontinuation was mainly for penitentiary reasons (40.3 %): release or transfer between prisons.

The rate of sustained viral response (SVR) was 52.1 % by ITT and 76.9 % by observed treatment (OT). SVR was higher among patients with genotype 2 or 3, and those with low baseline HCV-RNA. We did not observe any differences between individuals with and without PD in term of SVR, HCV genotype or HIV infection.

Conclusions

Our results support the safety and clinical effectiveness of the treatment of chronic HCV infection in correctional facilities, both in prisoners with PD and those without. Our data support non-discrimination between patients with and without PD when offering treatment for HCV infection to prison inmates.

Can hepatitis C be eradicated in the United States?

The advent of highly effective antiviral regimens will make the eradication of hepatitis C in high-income countries such as the United States technically feasible. But eradicating hepatitis C will require escalating our response to the epidemic in key domains, including surveillance and epidemiology, prevention, screening, care and treatment, policy, research, and advocacy. Surveillance must be nimble enough to quickly assess the magnitude of new transmission patterns as they emerge. Basic prevention strategies - community-based outreach and education, testing and counseling, and access to sterile injection equipment and opioid substitution therapies - must be scaled up and adapted to target groups in which new epidemics are emerging. All adults should be screened for hepatitis C, but special efforts must focus on groups with increased prevalence through community outreach and rapid testing. Government, industry, and payers must work together to assure full access to health services and antiviral drugs for everyone who is infected. Access to the new regimens must not be compromised by excessively high prices or arbitrary payer restrictions. Partnerships must be forged between hepatitis providers and programs that serve people who inject illicit drugs. Healthcare providers and systems, especially primary care practitioners, need education and training in treating hepatitis C and caring for substance-using populations. Services must be provided to the disadvantaged and stigmatized members of society who bear a disproportionate burden of the epidemic. Environments must be created where people who use drugs can receive prevention and treatment services without shame or stigma. Action is needed to end the policy of mass incarceration of people who use drugs, reduce the stigma associated with substance use, support the human rights of people who use drugs, expand social safety net services for the poor and the homeless, remove the legal barriers to hepatitis C prevention, and build public health infrastructure to reach, engage, and serve marginalized populations. Governments must take action to bring about these changes. Public health agencies must work with penal institutions to provide prevention and treatment services, including antiviral therapy, to those in need in jails and prisons or on probation or parole. Research is needed to guide efforts in each of these domains. Strong and sustained political advocacy will be needed to build and sustain support for these measures. Leadership must be provided by physicians, scientists, and the public health community in partnership with community advocates and people living with or at risk for hepatitis C. Eliminating hepatitis C from the United States is possible, but will require a sustained national commitment to reach, test, treat, cure, and prevent every case. With strong political leadership, societal commitment, and community support, hepatitis C can be eradicated in the United States. If this is to happen in our lifetimes, the time for action is now. This article forms part of a symposium in Antiviral Research on "Hepatitis C: next steps toward global eradication."
