Abstract
In 2016, the Global Health Sector Strategy, ratified by the 69th World Health Assembly, set the ambitious goal of eliminating hepatitis C virus (HCV) and hepatitis B virus infections by 2030, emphasizing the importance of national screening programmes. Achieving this goal depends on each country's ability to identify and treat 80% of chronic hepatitis C cases, a critical threshold set by the World Health Organization. Traditionally, estimates of HCV prevalence have been based on interferon era studies that focused on high-risk subgroups rather than the general population. In addition, the incomplete data available from national registries also limited the understanding of HCV prevalence. The 2016 report from the European Centre for Disease Prevention and Control highlighted that HCV rates varied across European counties, ranging from .1% to 5.9%. However, data were only available for 13 countries, making the overall picture less clear. Additionally, the epidemiological data may have underestimated the true burden of HCV due to lack of awareness among those with chronic infection. The main objective of this review is to provide a comprehensive summary of HCV epidemiology in Europe in the current era of direct-acting antivirals (DAAs). The data included in the analysis range from the end of 2013 to December 2023 and have been categorised according to the United Nations Geoscheme. The resulting synthesis underscores the noteworthy impact of DAA treatment on the epidemiological situation.

Seroepidemiological Investigation of Hepatitis B and C Prevalence and Associated Factors Among People in Custody at Zahedan Central Prison. ARCHIVES OF IRANIAN MEDICINE 2024; 27:298-304. [PMID: 38855799 PMCID: PMC11264623 DOI: 10.34172/aim.23553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Accepted: 10/11/2023] [Indexed: 06/11/2024]
Abstract
BACKGROUND On a global scale, approximately 350 million are affected by hepatitis B, and 71 million by hepatitis C. People in custody face elevated risks for these infections. The prevalence and risk factors in Iranian prisons are insufficiently documented. The principal objective of this study was to ascertain the prevalence of hepatitis B and C, coupled with the identification of pertinent influencing factors, within the confines of Zahedan central prison, situated in the southeastern region of Iran. METHODS In 2019, we conducted an analytical cross-sectional study involving 407 people in custody, using stratified random sampling. To definitively diagnose hepatitis C virus (HCV) infection (P<0.05), a checklist developed by the researchers, along with enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) techniques, were employed. RESULTS This study comprised 406 participants (96.3% male) with a median age of 32 years (27-38). Approximately 62% were married, and a substantial proportion of the participants had low education levels (47%), unemployment (64%), and belonged to the Baloch ethnicity (64%). The overall prevalence of hepatitis C and B infections was 2.7% and 10.6%, respectively. Tattooing (adjusted odds ratio [AOR]: 2.07, 95% CI: 1.9-4.5) and marriage (AOR: 1.78, 95% CI: 1.05-3.04) were identified as risk factors for hepatitis B. Moreover, hepatitis C showed a statistically significant association with a family history of hepatitis B and C (AOR: 3.31, 95% CI: 3.93-24.64) and intravenous (IV) drug use (AOR: 7.01, 95% CI: 1.52-32.78) according to the multivariable logistic regression analysis. CONCLUSION The prevalence of hepatitis B and C was higher among people in custody in Zahedan central prison. Consequently, targeted interventions are vital to address and reduce viral hepatitis burden in custodial settings.

Abstract
Hepatitis C virus infection (HCV) is prevalent in prisons. Therefore, effective prison HCV services are critical for HCV elimination programmes. We aimed to evaluate the efficacy of a regional HCV prison testing and treatment programme. Between July 2017 and June 2022, data were collected prospectively on HCV test offer and uptake rates, HCV Antibody (HCV-Ab) and HCV-RNA positivity, treatment starts and outcomes for new inmates incarcerated in three prisons. Rates of HCV-Ab and RNA positivity at reception, incidence of new HCV infections and reinfection following treatment were determined. From a total of 39,652 receptions, 33,028 (83.3%) were offered HCV testing and 20,394 (61.7%) completed testing. Including all receptions, 24.5% of tests (n = 4995) were HCV-Ab positive and 8.4% of tests (n = 1713) were HCV-RNA positive. When considering the first test for each individual (median age 34 years; 88.1% male), 14.8% (n = 1869) and 7.2% (n = 905) were HCV-Ab and HCV-RNA positive, respectively. The incidence of new HCV-Ab and RNA positivity was 5.1 and 3.3 per 100 person-years, respectively. Of 1145 HCV viraemic individuals, 18 died within 6 months and 150 were rapidly transferred out of area, leaving 977 individuals with outcomes. Of these, 835 (85.5%) received antivirals and 47 spontaneously cleared the infection, leaving 95 (9.7%) untreated. 607 (72.7%) achieved SVR. 95 patients had reinfection post-treatment (rate 10.1 cases per 100 person-years). Testing for HCV has increased in our prisons and the majority with viraemia are initiated on antiviral treatment. Reassuringly, a significant fall in frequency of HCV-RNA positivity at prison reception was observed suggesting progress towards HCV elimination.

Abstract
BACKGROUND/AIMS In 2016, World Health Organization introduced global goals to eliminate hepatitis C virus by 2030. The aim of this study is to analyze the epidemiologic and economic burden of hepatitis C virus in Turkey and compare current practice (regular care) with a hypothetical active screening and treatment approach (active scenario). MATERIALS AND METHODS A Markov model was used to analyze and compare regular care with a scenario developed by experts including the screening and treatment of all acute and chronic hepatitis C virus infections between 2020 and 2050. General and targeted populations were focused. The model reflected the natural history of the disease, and the inputs were based on a literature review and expert opinions. Costs were provided by previous studies and national regulations. RESULTS The active scenario resulted in higher spending for all groups compared with regular care in the first year. Cumulative costs were equalized in the 8th, 12th, 13th, and 16th year and followed by cost-savings of 49.7 million, 1.1 billion, 288.6 million, and 883.4 million Turkish liras in 20 years for prisoners, refugees, people who inject drugs (PWID), and all population, respectively. In all groups, the mortality was found to be lower with the active scenario. In total, 62.8% and 50.6% of expected deaths with regular care in 5 and 20 years, respectively, were prevented with the active scenario. CONCLUSIONS An active screening and treatment approach for hepatitis C virus infection could be cost-effective for PWID, prisoners, and refugees. Almost two-thirds of deaths in regular care could be prevented in 5 years' time with this approach.

Abstract
BackgroundAccording to the World Health Organization, hepatitis C virus (HCV) infection should be under control by 2030.AimOur aim was to describe the size and temporal changes in reported cases of chronic HCV infection in Denmark and Sweden and to estimate the size of the hidden (undiagnosed) population born before 1965.MethodsWe extracted all HCV infections reported to national surveillance systems in Denmark and Sweden from 1990 to 2020. Prediction of the size of the hidden HCV-infected population was restricted to the cohort born before 1965 and cases reported up to 2017. We applied a model based on removal sampling from binomial distributions, estimated the yearly probability of diagnosis, and deducted the original HCV-infected population size.ResultsDenmark (clinician-based) reported 10 times fewer hepatitis C cases annually than Sweden (laboratory and clinician-based), peaking in 2007 (n = 425) and 1992 (n = 4,537), respectively. In Denmark, the birth year distribution was monophasic with little change over time. In recent years, Sweden has had a bimodal birth year distribution, suggesting ongoing infection in the young population. In 2017, the total HCV-infected population born before 1965 was estimated at 10,737 living persons (95% confidence interval (CI): 9,744-11,806), including 5,054 undiagnosed, in Denmark and 16,124 (95% CI: 13,639-18,978), including 10,580 undiagnosed, in Sweden.ConclusionsThe reporting of HCV cases in Denmark and Sweden was different. For Denmark, the estimated hidden population was larger than the current national estimate, whereas in Sweden the estimate was in line with the latest published numbers.

Abstract
Background The introduction of highly effective direct-acting antiviral therapy has changed the hepatitis C virus (HCV) treatment paradigm. However, a recent update on HCV epidemiology in incarcerated settings is necessary to accurately determine the extent of the problem, provide information to policymakers and public healthcare, and meet the World Health Organization's goals by 2030. This systematic review and meta-analysis were performed to determine the prevalence of HCV Ab and RNA in incarcerated settings. Methods For this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, and Web of Science for papers published between January 2013 and August 2021. We included studies with information on the prevalence of HCV Ab or RNA in incarcerated settings. A random-effects meta-analysis was done to calculate the pooled prevalence and meta-regression to explore heterogeneity. Results Ninety-two unique sources reporting data for 36 countries were included. The estimated prevalence of HCV Ab ranged from 0.3% to 74.4%. HCV RNA prevalence (available in 46 sources) ranged from 0% to 56.3%. Genotypes (available in 19 sources) 1(a) and 3 were most frequently reported in incarcerated settings. HCV/HIV coinfection (available in 36 sources) was highest in Italy, Estonia, Pakistan, and Spain. Statistical analysis revealed that almost all observed heterogeneity reflects real differences in prevalence between studies, considering I2 was very high in the meta-analysis. Conclusions HCV in incarcerated settings is still a significant problem with a higher prevalence than in the general population. It is of utmost importance to start screening for HCV (Ab and RNA) in incarcerated settings to give clear, reliable and recent figures to plan further treatment. This is all in the context of meeting the 2030 WHO targets which are only less than a decade away.

Abstract
Background Valve surgery guidelines for infective endocarditis (IE) are unchanged over decades and nationwide data about the use of valve surgery do not exist.
Methods We included patients with first-time IE (1999–2018) using Danish nationwide registries. Proportions of valve surgery were reported for calendar periods (1999–2003, 2004–2008, 2009–2013, 2014–2018). Comparing calendar periods in multivariable analyses, we computed likelihoods of valve surgery with logistic regression and rates of 30 day postoperative mortality with Cox regression. Results We included 8804 patients with first-time IE; 1981 (22.5%) underwent surgery during admission, decreasing by calendar periods (N = 360 [24.4%], N = 483 [24.0%], N = 553 [23.5%], N = 585 [19.7%], P = < 0.001 for trend). For patients undergoing valve surgery, median age increased from 59.7 to 66.9 years (P ≤ 0.001) and the proportion of males increased from 67.8% to 72.6% (P = 0.008) from 1999–2003 to 2014–2018. Compared with 1999–2003, associated likelihoods of valve surgery were: Odds ratio (OR) = 1.14 (95% CI: 0.96–1.35), OR = 1.20 (95% CI: 1.02–1.42), and OR = 1.10 (95% CI: 0.93–1.29) in 2004–2008, 2009–2013, and 2014–2018, respectively. 30 day postoperative mortalities were: 12.7%, 12.8%, 6.9%, and 9.7% by calendar periods. Compared with 1999–2003, associated mortality rates were: Hazard ratio (HR) = 0.96 (95% CI: 0.65–1.41), HR = 0.43 (95% CI: 0.28–0.67), and HR = 0.55 (95% CI 0.37–0.83) in 2004–2008, 2009–2013, and 2014–2018, respectively. Conclusions On a nationwide scale, 22.5% of patients with IE underwent valve surgery. Patient characteristics changed considerably and use of valve surgery decreased over time. The adjusted likelihood of valve surgery was similar between calendar periods with a trend towards an increase while rates of 30 day postoperative mortality decreased.

Abstract
Denmark has signed the WHO strategy to eliminate hepatitis C virus (HCV). In the absence of a national strategy for elimination, a local action plan was developed in the Region of Southern Denmark (RSD). The aim of the strategy is to diagnose 90% of HCV-infected persons and treat 80% of those diagnosed by 2025. The strategy was developed by reviewing Danish data on HCV epidemiology and drug use to identify key populations for screening, linkage to care, and treatment. Based on available published data from 2016, an estimated 3028 persons in the RSD were HCV-RNA positive (population prevalence 0.21%). Of these, 1002 were attending clinical care, 1299 were diagnosed but not in clinical care, and 727 were undiagnosed. Three different interventions targeting the HCV-infected population and two interventions for HCV surveillance are planned to achieve elimination. The “C-Free-South” strategy aims to eliminate HCV in our region by identifying (90%) and treating (80%) of infected persons by the end of 2025, 5 years earlier than the WHO elimination target date.

Abstract
BACKGROUND As direct-acting antiviral treatment for hepatitis C virus (HCV) is widely available in Denmark, the hindrance to achieving elimination lies in identifying infections. Effective identification relies on screening in high-risk populations. Here, we report the outcomes of a risk-based, point-of-care (POC) screening strategy in a Danish emergency department (ED). METHODS During a three-month period, ED patients at Odense University Hospital were screened for risk factors and offered POC HCV-antibody (HCV-Ab) testing. Reactive results were followed up by confirmatory venepuncture testing. The main outcome measure was prevalence of HCV-antibodies. Secondary outcome measures were prevalence of risk factors and an evaluation of feasibility of ED screening. RESULTS During study times, 1831 (55.7%) of 3288 presentations to the ED were eligible for screening. Six hundred and seventy-three (36.8%) were approached, of which 514 (28.1%) participated and 159 (8.7%) declined. Of 514 participants, 339 (66%) reported one or more risk factors, and 489 (95.1%) underwent HCV-Ab testing. Four (0.8%) had a reactive HCV-Ab test. No active infections of HCV were found. The risk factor of having injected drugs was present in all HCV-Ab positive patients. Compared to participants, patients who could not be approached had a lower prevalence of previously diagnosed hepatitis C- and risk-factor-associated diagnoses. CONCLUSIONS The risk factor of injecting drug use had the highest yield for HCV-Ab positivity. Additional risk factors did not contribute to case-finding. This screening strategy was feasible but ineffective. Further testing strategies will be necessary to identify the remaining hepatitis C patients in Denmark.

[PMID: 34267568 PMCID: PMC8275151 DOI: 10.2147/jbm.s314556] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Accepted: 06/16/2021] [Indexed: 12/21/2022] Open
Abstract
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.

New hepatitis C virus infection, re-infection and associated risk behaviour in male Irish prisoners: a cohort study, 2019. ACTA ACUST UNITED AC 2021; 79:97. [PMID: 34103080 PMCID: PMC8186141 DOI: 10.1186/s13690-021-00623-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 05/30/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Prisoners are recognised as a high-risk population and prisons as high-risk locations for the transmission of hepatitis c virus (HCV) infection. Injecting drug use (IDU) is the main driver of HCV infection in prisoners and harm reduction services are often suboptimal in prison settings. HCV prevalence and incident data in prisoners is incomplete which impacts the public health opportunity that incarceration provides in identifying, treating and preventing HCV infection. The aim of this study is to identify new HCV infection and associated risk factors in an Irish male prison. METHODS We conducted a follow up (18-month) cohort study on prisoners who had previously tested negative, self-cleared or had been successfully treated for HCV infection. We conducted the study in a male medium security prison located in Dublin Ireland (Mountjoy Prison) using HCV serology, a review of medical records and a researcher-administered questionnaire. RESULTS 99 prisoners with a mean age of 33.2 yrs. participated in the study and 82(82.8%) completed a research-administered questionnaire. Over half (51%) had a history of drug use from a young age (14.8 yrs.), 49.9% a history of heroin use and 39% a history of IDU. The prevalence of HIV and hepatitis B virus core antibody was 3% and HCV antibody was 22.2%. No new HCV infections were identified in those who had never been infected (n = 77), had self-cleared (n = 9) or achieved sustained virological response (n = 12). Small numbers of prisoners continued to engage in risk-behaviour including, IDU both in the prison (n = 2) and the community (n = 3), sharing syringes (n = 1) and drug taking paraphernalia (n = 6) and receiving non-sterile tattoos (n = 3). CONCLUSION Despite the high numbers of Irish prisoners with a history of IDU and HCV infection, new HCV infection is low or non-existent in this population. Small numbers of prisoners continue to engage in risk behaviour and larger studies are required to further understand HCV transmission in this cohort in an Irish and international context.

Abstract
(1) Background: The World Health Organization adopted a strategy for the Global Health Sector on Viral Hepatitis in 2016, with the main objective of eliminating hepatitis C virus (HCV) by 2030. In this work, we aimed to evaluate the prevalence of HCV infection and risk factors in a Romanian village using population-based screening as part of the global C virus eradication program. (2) Methods: We conducted a prospective study from March 2019 to February 2020, based on a strategy as part of a project designed to educate, screen, treat and eliminate HCV infection in all adults in a village located in Northeastern Romania. (3) Results: In total, 3507 subjects were invited to be screened by rapid diagnostic orientation tests (RDOT). Overall, 2945 (84%) subjects were tested, out of whom 78 (2.64%) were found to have positive HCV antibodies and were scheduled for further evaluation in a tertiary center of gastroenterology/hepatology in order to be linked to care. In total, 66 (85%) subjects presented for evaluation and 55 (83%) had detectable HCV RNA. Of these, 54 (98%) completed antiviral treatment and 53 (99%) obtained a sustained virological response. (4) Conclusions: The elimination of hepatitis C worldwide has a higher chance of success if micro-elimination strategies based on mass screening are adopted.

Abstract
Hepatitis C virus (HCV) is a global public health problem in correctional settings. The International Network on Health and Hepatitis in Substance Users-Prisons Network is a special interest group committed to advancing scientific knowledge exchange and advocacy for HCV prevention and care in correctional settings. In this Review, we highlight seven priority areas and best practices for improving HCV care in correctional settings: changing political will, ensuring access to HCV diagnosis and testing, promoting optimal models of HCV care and treatment, improving surveillance and monitoring of the HCV care cascade, reducing stigma and tackling the social determinants of health inequalities, implementing HCV prevention and harm reduction programmes, and advancing prison-based research.

Abstract
Hepatitis C virus (HCV) is highly prevalent in the criminal justice system and in persons who inject drugs, particularly opioids. Data on the impact of medications for opioid use disorder (MOUD) are abundant for infectious and noninfectious outcomes but are limited for justice-involved settings. This systematic review and meta-analysis focuses on the impact of MOUD on HCV incidence for persons in prisons and jails. Six studies were included in the qualitative synthesis, of which four were included for meta-analysis. A varied MOUD effect on HCV incidence was observed in part due to wide variability in prison and jail risk environments.

Abstract
BACKGROUND Hepatitis C is highly prevalent among people who use drugs (PWUD), and the hepatitis C virus (HCV) epidemic is less characterised in Norway. The aims of the study were to assess the prevalence and treatment willingness in high-risk populations by reaching out to frequently visited sites for high-risk populations. METHODS Individuals from high-risk populations were included from September 2015 to March 2017. Two dedicated study nurses frequently visited the local opioid substitution clinic, outpatient clinics, PWUD day centres, local prison, and refugee centre in Trondheim, Norway. Demographic data, risk behaviour, and clinical symptoms were obtained by study questionnaire. Subjects with anti-HCV+ rapid test were subsequently tested for HCV RNA and genotyped. Viraemic patients were offered referral for HCV treatment evaluation. RESULTS A total of 381 participants were included in the study: 52 immigrants, 62 prisoners, and 267 PWUD. The anti-HCV prevalence rates were 0% (n = 0) in immigrants, 40% (n = 25) in prisoners, and 61% (n = 164) in PWUD, with 24% (n = 15) of prisoners and 42% (n = 108) of PWUD being viraemic. Of those qualifying for treatment (n = 31), 30 wished to be evaluated. CONCLUSION This study showed high HCV prevalence in prisoners and PWUD and that infected high-risk patients were interested in treatment evaluation.

Abstract
BACKGROUND Chronic hepatitis C (CHC) can be eliminated as a public health threat by meeting the WHO targets: 90% of patients diagnosed and 80% treated by 2030. To achieve and monitor progress towards elimination, an updated estimate of the size of the CHC population is needed, but Denmark has no complete national CHC register. By combining existing registers in 2007, we estimated the population living with CHC to be 16,888 (0.38% of the adult population). AIM To estimate the population living with diagnosed and undiagnosed CHC in Denmark on 31 December 2016. Among additional aims were to estimate the proportion of patients attending specialised clinical care. METHODS People with diagnosed CHC were identified from four national registers. The total diagnosed population was estimated by capture-recapture analysis. The undiagnosed population was estimated by comparing the register data with data from two cross-sectional surveys. RESULTS The population living with diagnosed CHC in Denmark was 7,581 persons (95%CI: 7,416-12,661) of which 6,116 (81%) were identified in the four registers. The estimated undiagnosed fraction was 24%, so the total CHC infected population was 9,975 corresponding to 0.21% of the adult population (95%CI: 9,758-16,659; 0.21%-0.36%). Only 48% of diagnosed patients had received specialised clinical care. CONCLUSION CHC prevalence in Denmark is declining and 76% of patients have been diagnosed. Linking diagnosed patients to care and increasing efforts to test people with former or current drug use will be necessary to achieve CHC elimination.
