The prevalence of HCV antibody in South Australian prisoners

Global prevalence of hepatitis C in prisoners: a comprehensive systematic review and meta-analysis

Hepatitis C virus (HCV), one of the most significant causes of liver inflammation, has a high annual mortality rate. The unfavorable hygiene conditions and inadequate health monitoring in many prisons increase the risk of blood-borne infections such as hepatitis C. The growing incidence of this disease among prisoners results in overspill transmission to the general population from undiagnosed prisoners that have been released. Therefore, the aim of this study was to investigate the prevalence of hepatitis C among the world's prison population. A systematic review and meta-analysis of studies on the prevalence of hepatitis C was carried out using the keywords "Prevalence", "Hepatitis C", and "Prisoner" in the Iranian and international databases SID, MagIran, Iran Doc, Science Direct, Scopus, PubMed, and Web of Science (WoS) from January 1990 to September 2020. After transferring the articles to the information management software EndNote and eliminating duplicate studies, the remaining studies were reviewed based on inclusion and exclusion criteria, three stages of primary and secondary evaluation, and qualitative evaluation. Comprehensive meta-analysis software and Begg and Mazumdar and I² tests were used for data analysis and assessment of dissemination bias, and heterogeneity, respectively. Out of 93 studies (22 from Asia, 26 from Europe, seven from Africa, 29 from America, and nine from Australia) with a total sample size of 145,823 subjects, the prevalence of hepatitis C in prisoners worldwide was estimated to be 17.7% (95% confidence interval, 15-20.7%). The highest prevalence of hepatitis C on the continents included in this study was reported in prisoners incarcerated in Australia and Oceania, with 28.4% (95% CI: 21.6-36.4) in nine studies, and Europe, with 25.1% (95% CI: 19.4-31.8) in 26 studies. All studies used an ELISA test for the detection of HCV antibodies. The results showed a prevalence of HCV of 17.7% in prisoners worldwide, ranging between 10 and 30% over five continents (Asia, Europe, America, Africa, and Australia and Oceania). The highest prevalence was reported in Australia and Oceania (28.4%), indicating the need to pay more attention to this issue on the continent. It is necessary to reduce the incidence of the disease in prisons by appropriate policy-making and the development of accurate and practical programs, including the distribution of free syringes and examination, testing, and screening of prisoners.

Hepatitis B and Hepatitis C Viral Infections and Associated Factors Among Prisoners in Northeast Ethiopia

BACKGROUND

Hepatitis is an inflammation of the liver and often caused by viruses. Hepatitis viruses are the leading causes of liver-related morbidity and mortality worldwide, with Hepatitis B and C viruses share the great majority. Studies have shown that prison settings are one of the high-risk environments for the transmission of these viruses. However, there is limited information on the seroprevalence and associated factors of hepatitis B and C viral infection among Ethiopian prisoners.

METHODS

A facility-based cross-sectional study was conducted among 339 prisoners in Dessie town, Ethiopia from February to April 2020. Hepatitis B surface antigen and antibody against hepatitis C virus in serum were determined using Enzyme-Linked Immunosorbent Assay. We imputed the data using "EpiData 3.1" software and exported it to Statistical Package for Social Sciences version 20.0 for analysis, and a p-value of <0.05 was considered statistically significant.

RESULTS

The overall seroprevalence of hepatitis B surface antigen and anti-hepatitis C virus among prisoners was 22/339 (6.5%) (95% CI = 3.8-9.4), and 4/339 (1.2%) (95% CI = 0.0-2.4), respectively. Multiple sexual partners, previous imprisonment, body tattooing, and contact with the jaundiced patient were independently associated with hepatitis B virus infection. Prisoners who had a history of blood transfusion, and dental extraction were independently associated with hepatitis C virus infection.

CONCLUSION

The seroprevalence of hepatitis B and hepatitis C viral infection among Dessie town prisoners was intermediate and low, respectively. The finding of a significant association between the presence of Hepatitis B surface antigen and hepatitis C virus antibodies among prisoners and factors calls for the need of serological testing for both Hepatitis B and C viruses to high-risk individuals. Strengthening screening strategies and prevention programs in prison settings is advisable to prevent disease transmission.

Viral hepatitis in correctional facilities in the Northern Territory of Australia 2003-2017

Background

The demographic of Northern Territory prison population differs than elsewhere in Australia and the prevalence of hepatitis B and hepatitis C may therefore be somewhat different from other jurisdictions. There has been no study which has specifically described the serological results of a large proportion of prisoners in Northern Territory correctional facilities over an extended period of time.

Methods

This retrospective longitudinal study reviewed serological results and testing rates for hepatitis B, and hepatitis C performed in correctional facilities in the Northern Territory of Australia between July 1st, 2003 and June 30th, 2017.

Results

The proportion of positive records over 14 years for hepatitis B surface antigen (HBsAg) was 641/12,066 (5.3, 95% CI 4.9–5.7), for hepatitis B core antibody (anti-HBc) 4937/12,138 (40.1, 95%CI 39.8–41.6), for hepatitis B surface antibody (anti-HBs) 6966/13,303 (52.4, 95% CI 51.5–53.2), and for hepatitis C antibody 569/12,153 (4.7, 95% CI 4.3–5.1). The proportion of prisoners tested for hepatitis B and hepatitis C has decreased since 2015, while a high proportion of prisoners remain non-immune to hepatitis B.

Conclusion

There is a relatively high proportion of positive serological markers of hepatitis B, and a lower proportion of positive hepatitis C serology in the Northern Territory’s correctional facilities compared to overall Australian rates. As the proportion of prisoners tested for hepatitis B and C has decreased recently, and a high proportion of prisoners remain non-immune to hepatitis B, there are opportunities to increase testing and vaccination rates in this population.

Hepatitis B and Hepatitis C in prisons: a prevalence study

PURPOSE

Prisons, which are hazardous places for various contagious diseases, carry additional risks for HBV and HCV because of the communal lifestyle (common use of tools like razor blades, tattoo applications, intravenous drug use and homosexual intercourse). The purpose of this paper is to determine the prevalence of HBV and HCV, and also provide information for prisoners in this respect.

DESIGN/METHODOLOGY/APPROACH

This study included 180 prisoners from the Buca F-Type Closed Prison, and 180 prisoners from the Foça Open Prison in Turkey. After the training seminars, serum levels of HBsAg, anti HBs, anti HBc total and anti HCV in the prisoners were assessed using the MICROELISA method.

FINDINGS

All the prisoners were male. The mean age was 40(21-73) years. According to the results of 360 prisoners from both prisons, 17 (4.7 percent) prisoners were HBsAg positive and were diagnosed as HBV. Isolated anti HBs was positive in 33 (9.1 percent) prisoners who had been previously vaccinated. In 25 (6.9 percent) prisoners isolated Anti HBc total was positive, and in 61 (16.9 percent) prisoners both Anti HBs and Anti HBc total was positive in those who were considered to be recovered from the HBV. Anti HCV was positive in 2 (0.5 percent) prisoners; the process was repeated twice, and found to be repeatedly positive. Coinfection of HBV and HCV was not detected.

RESEARCH LIMITATIONS/IMPLICATIONS

In this study, the prevalence of HBV and HCV was determined to be similar to those in the normal population. However, it is not expedient to generalize this result and apply it to all prisons. For the sake of public health, prisons should be scanned for infectious diseases, and vaccinations must be applied as necessary, in order to provide protection.

ORIGINALITY/VALUE

It is a study to determine the prevalence of HBV and HCV in the prisoner population, which constitute one of the risk groups because of the communal lifestyle (common use of some tools such as the razor blade, tattoo applications, intravenous drug use and homosexual intercourse), and to compare the results with other groups in Turkey and globally.

Healthcare delivery for women in prison: a medical record review

When women come into prison, many have unmet health needs. In this study we examine the health care provided to women in prison and their identified health needs, and discuss opportunities for improved healthcare delivery. We undertook a medical record review of women released from a minimum 6-week period of incarceration in New South Wales correctional centres between May 2013 and January 2014. Records from 231 periods of incarceration were reviewed. At reception, 52% of women were identified as having anxiety or depression. Hearing health was not documented despite 30% of records being of women from an Aboriginal and Torres Strait Islander background, a high-risk group for whom hearing screening is recommended. Most women had multiple in-prison clinical contacts, including interactions with general and specialised nurses (97%), general practitioners (65%) and psychiatrists (35%). At release, 49% were on psychotropic medication and most required ongoing management for: mental health (71%), substance misuse (65%) and physical health (61%) problems. External specialist appointments were pending in 7% at release. Health management plans generated in prison were not always completed before release for reasons including custodial factors and waits for hospital-based appointments. Provision of effective health care in prison requires improved integration with community health services, including timely access to a wide range of health services while women are in prison, and continuity of care at release.

Incidence and correlates of hepatitis C virus infection in a large cohort of prisoners who have injected drugs

BACKGROUND

Hepatitis C virus (HCV) infection is common among prisoners, particularly those with a history of injecting drug use (IDU). Incarcerated people who inject drugs frequently report high-risk injecting practices both in prison and in the community. In spite of rising morbidity and mortality, utilisation of HCV-related services in Australia has been persistently low. This study aimed to describe the incidence, prevalence and correlates of HCV seropositivity in a large cohort of prisoners who have injected drugs, and to identify correlates of receiving confirmation of active infection.

METHODS

Data-linkage to a State-wide statutory notifiable diseases surveillance system was used to investigate the incidence of notified HCV seropositivity, seroconversion and confirmed HCV infection in a cohort of 735 prisoners with a history of IDU, over 14 years of follow up. Hepatitis C test results from prison medical records were used to identify correlates of testing positive in prison.

RESULTS

The crude incidence of HCV notification was 5.1 cases per 100 person-years. By the end of follow up, 55.1% of the cohort had been the subject of a HCV-related notification, and 47.4% of those tested in prison were HCV seropositive. In multivariable analyses, injecting in prison was strongly associated with HCV seropositivity, as was opioid use compared to injection of other drugs. The rate of reported diagnostic confirmation among those with notified infections was very low, at 6.6 confirmations per 100 seropositive participants per year.

CONCLUSIONS

Injecting drugs in prison was strongly associated with HCV seropositivity, highlighting the need for increased provision of services to mitigate the risk of transmission within prisons. Once identified as seropositive through screening, people with a history of IDU and incarceration may not be promptly receiving diagnostic services, which are necessary if they are to access treatment. Improving access to HCV-related services will be of particular importance in the coming years, as HCV-related morbidity and mortality is increasing, and next generation therapies are becoming more widely available.

Prevalence of HCV risk behaviors among prison inmates: tattooing and injection drug use

Hepatitis C virus (HCV) is the most common blood-borne chronic viral infection in the United States and it is over represented in incarcerated populations. This study estimates if in prison tattooing is associated with self reported HCV infection in a probabilistic sample of 1,331 sentenced inmates in Puerto Rico prisons anonymously surveyed in 2004, who had previously been tested for HCV. Analysis were carried out with the total sample and among non-injectors (n=796) to control for injection drug use (IDU) and other confounders. Nearly 60% of inmates had acquired tattoos in prison. HCV was reported by 27% of subjects in the total sample and by 12% of non-injectors who had undergone tattoos in prison. IDU was the strongest predictor of HCV in the total sample (OR=5.6, 95% CI=3.2-9.7). Among non injectors, tattooing with reused needles or sharp objects and/ or reusing ink was positively associated with HCV self-report (OR=2.6, 95% CI=1.3-5.5). Tattooing is a common occurrence in this prison setting. Findings suggest that preventive interventions are required to reduce the risk of HCV transmission through unsterile tattooing and injection practices.

Prevalence, genotypes and factors associated with HCV infection among prisoners in Northeastern Brazil

AIM: To determine hepatitis C virus (HCV) seroprevalence and its genotypes, and to identify the factors associated with HCV infection.

METHODS: This cross-sectional study, conducted in two prisons (one male and one female) in the State of Sergipe, Brazil, comprised 422 subjects. All of the prisoners underwent a rapid test for the detection of HCV antibodies. Patients with a positive result were tested for anti-HCV by enzyme linked immunosorbent assay and for HCV RNA by qualitative polymerase chain reaction (PCR). The virus genotype was defined in every serum sample that presented positive for PCR-HCV. In order to determine the factors independently associated with positive serology for HCV, multivariate logistic regression was used.

RESULTS: HCV seroprevalence was 3.1%. Of the 13 subjects with positive anti-HCV, 11 had viremia confirmed by PCR. Of these, 90.9% had genotype 1. A total of 43 (10.2%) were injecting drug users, and HCV seroprevalence in this subgroup was 20.6%. The variable most strongly associated with positive serology for HCV was use of injecting drugs [odds ratio (OR), 23.3; 95% confidence interval (CI), 6.0-90.8]. Age over 30 years (OR, 5.5; 95%CI, 1.1-29.2), history of syphilis (OR, 9.8; 95%CI, 1.7-55.2) and history of household contact with HCV positive individual (OR, 14.1; 95%CI, 2.3-85.4) were also independently associated with HCV infection.

CONCLUSION: Most of the HCV transmissions result from parenteral exposure. However, there is evidence to suggest a role for sex and household contact with an infected subject in virus transmission.

Testing for sexually transmitted infections and blood borne viruses on admission to Western Australian prisons

Background

Prison populations are known to be at high risk of sexually transmitted infections (STIs) and blood borne viruses (BBVs). In accordance with State health guidelines, the Western Australian Department of Correctional Services' policy is to offer testing for STIs and BBVs to all new prison entrants. This audit was undertaken to assess the completeness and timeliness of STI and BBV testing among recent prison entrants in Western Australia, and estimate the prevalence of STIs and BBVs on admission to prison.

Methods

A retrospective audit of prison medical records was conducted among 946 individuals admitted to prison in Western Australia after the 1^st January 2005, and discharged between the 1^st January and 31^st December 2007 inclusive. Quota sampling was used to ensure adequate sampling of females, juveniles, and individuals from regional prisons. Main outcomes of interest were the proportion of prisoners undergoing STI and BBV testing, and the prevalence of STIs and BBVs.

Results

Approximately half the sample underwent testing for the STIs chlamydia and gonorrhoea, and almost 40% underwent testing for at least one BBV. Completeness of chlamydia and gonorrhoea testing was significantly higher among juveniles (84.1%) compared with adults (39.8%; p < 0.001), and Aboriginal prisoners (58.3%) compared with non-Aboriginal prisoners (40.4%; p < 0.001). Completeness of BBV testing was significantly higher among adults (46.5%) compared with juveniles (15.8%; p < 0.001) and males (43.3%) compared with females (33.1%; p = 0.001). Among prisoners who underwent testing, 7.3% had a positive chlamydia test result and 24.8% had a positive hepatitis C test result.

Conclusion

The documented coverage of STI and BBV testing among prisoners in Western Australia is not comprehensive, and varies significantly by age, gender and Aboriginality. Given the high prevalence of STIs and BBVs among prisoners, increased test coverage is required to ensure optimal use of the opportunity that prison admission presents for the treatment and control of STIs and BBVs among this high risk group.

Substance use patterns in newly admitted male and female South Australian prisoners using the WHO-ASSIST (Alcohol, Smoking and Substance Involvement Screening Test)

OBJECTIVE

To report on the patterns of substance use in newly admitted male and female South Australian prisoners using the WHO-ASSIST screening tool (Alcohol, Smoking and Substance Involvement Screening Test) and observe the feasibility of using the ASSIST and associated Brief Intervention in this population.

DATA SOURCES

Results of the first 518 prisoners screened using ASSIST in South Australian reception prisons.

RESULTS

In the first 10 months of the implementation of the WHO ASSIST, 518 clients were assessed in the 3 metropolitan intake prisons in Adelaide, Australia. This represents 31% of all male and 35% of all female prisoners admitted over this period. Injecting drug use was reported in the previous 3 months by 55% of men and 51% of women. The six most common substances used at high and moderate risk levels, in order of prevalence (from high to low) in males were tobacco, cannabis, amphetamines, opiates, alcohol, and sedatives. In women the order was tobacco, amphetamines, cannabis, opiates and sedatives equal, and alcohol. Fifty percent of men and 33% of women were using four or more substances. Overall rates of substance use related risk amongst men coming into prison are slightly greater than for women. Accessing prisoners for screening within the first few days is difficult with 55% already being released or at court or other external appointments.

The 2004 Australian prison entrants' blood-borne virus and risk behaviour survey

OBJECTIVES

To assess the prevalence of blood-borne viruses and associated risk factors among prison entrants at seven Australian prisons across four States.

DESIGN

Consecutive cross-sectional design. Voluntary confidential testing of all prison entrants for serological markers of human immunodeficiency virus (HIV), hepatitis C (HCV) and hepatitis B (HBV) over 14 consecutive days in May 2004. Demographic data and data related to risks for blood-borne virus transmission, such as sexual activity, body piercing, tattooing, and injecting drug use, were collected.

RESULTS

National prevalence for HIV was 1%, hepatitis B core antibody 20%, and hepatitis C antibody 34%. Fifty-nine per cent of participants had a history of injecting drug use. Among injecting drug users, the prevalence of HIV was 1%, hepatitis C antibody 56%, and hepatitis B core antibody 27%. Forty-one per cent of those screened reported a previous incarceration. In the multivariate model, Queensland and Western Australian (WA) prison entrants were significantly less likely to test positive to HCV than those in New South Wales (NSW). Amphetamine was the most commonly injected drug in Queensland, Tasmania and WA. In NSW, heroin was the most common drug injected. In the multivariate analysis a history of injecting drug use, being aged 30 years or more, and a prior incarceration were positively associated with hepatitis C infection. For hepatitis B core antibody, age over 30 years and a history of injecting drug use were associated with an increased risk.

CONCLUSIONS

The findings support the view that prisoner populations are vulnerable to blood-borne virus infection, particularly hepatitis B and C. Prisoner populations should be included in routine surveillance programs so as to provide a more representative picture of blood-borne virus epidemiology in Australia.

Aboriginal incarceration: health and social impacts

Each year up to a quarter of all young Aboriginal men have direct involvement with correctional services, and Aboriginal prisoners currently represent 22% of the total Australian prisoner population. The high rates of repeated short-term incarceration experienced by Aboriginal people in Australia have a multitude of negative health effects for Aboriginal communities and the wider society, while achieving little in terms of increased community safety. Well identified health and social priorities for Aboriginal people affected by incarceration include housing and tenancy support; mental health and wellbeing, including family violence, grief and loss support; substance misuse support; general health services, including hepatitis C management; and social inclusion, including the need for family and community integration, skills development and employment. The post-release period is a crucial time for the provision of integrated health and social services to address these priorities and to break the cycle of incarceration. To achieve significant health gains for Aboriginal people, there is a need to develop a broader collaborative approach to primary health care, incorporating social health and justice perspectives as fundamental components of health care planning. Health and human services have a critical role to play in developing community-based solutions to reduce excessive incarceration rates for Aboriginal people.
