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.

Effect of a Community-Based Hepatitis B Virus Infection Detection Combined with Vaccination Program in China. Vaccines (Basel) 2021; 10:vaccines10010019. [PMID: 35062680 PMCID: PMC8777927 DOI: 10.3390/vaccines10010019] [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: 11/29/2021] [Revised: 12/16/2021] [Accepted: 12/21/2021] [Indexed: 12/26/2022] Open
Abstract
Evidence on the effectiveness of hepatitis B virus (HBV) infection screening and vaccination programs remains rare in China. We used a quasi-experimental method, propensity score matching, to evaluate the effects of a community-based HBV infection detection combined with vaccination (HBVIDV) program in a pilot. Data were retrieved from the HBVIDV program implemented between July 2019 and June 2020. Outcomes were the difference between the treatment and control groups in hepatitis B vaccination (≥1 dose), hepatitis B vaccine series completion (≥3 doses), and serologic evidence of vaccine-mediated immunity. Altogether, 26,180 individuals were included, where 6160 (23.5%) individuals were assigned to the treatment group, and 20,020 (76.5%) individuals were assigned to the control group. After propensity score matching, 5793 individuals were matched. The rates of hepatitis B vaccination, hepatitis B vaccine series completion, and prevalence of vaccine-mediated immunity in the treatment and control groups were 29.0% vs. 17.8%, 22.1% vs. 13.1%, and 38.2% vs. 27.6%, respectively. The HBVIDV program was significantly associated with increased hepatitis B vaccination rate (OR, 1.884, 95% CI 1.725-2.057), hepatitis B vaccine series completion rate (OR, 1.872, 95% CI 1.696-2.065), and prevalence of vaccine-mediated immunity (OR, 1.623, 95% CI 1.501-1.755). The greater magnitude of association between HBVIDV program and outcomes was observed among adults aged 35-54 years and adults who live in rural areas. The HBVIDV program was effective in increasing the hepatitis B vaccination rate, hepatitis B vaccine series completion rate, and prevalence of vaccine-mediated immunity among adults in the pilot. Further focusing the program on special populations and regions may produce more effective results.

Abstract
Background The hepatitis C virus (HCV) infection is a candidate disease for micro-elimination. Accurate baseline HCV prevalence estimation is essential to monitor progress to micro-elimination but can be methodologically challenging in low-endemic regions like the Netherlands due to lack of disaggregated data by age or risk-groups on the number of chronic HCV patients (i.e. HCV RNA positive). This study estimates the number of patients that has had a chronic HCV infection (ever-chronic) in the Utrecht region of the Netherlands. Methods In the Utrecht province in the Netherlands, positive HCV tests from the period 2001–2015 from one diagnostic center and four hospital laboratories were collected. A two-source capture-recapture method was used to analyze the overlap between the two registries (with 92% HCV RNA and 8% HCV immunoblot confirmed infections) to obtain the number of ever-chronic HCV infections in the Utrecht region. The Utrecht region was defined as an area with a 25 km radius from the Utrecht city center. The current viremic HCV prevalence was calculated by taking into account the proportion of cured and deceased HCV patients from a local HCV retrieval (REACH) project. Results The estimated number of ever-chronic HCV patients was 1245 (95% CI 1164–1326) and would indicate a prevalence of 0.10 (95% CI 0.09–0.10) in the Utrecht region. This is 30% (95% CI 21–38%) more than the number of known HCV patients in the records. The ever-chronic HCV prevalence was highest in the 1960–1969 age cohort (0.16; 95% CI 0.14–0.18). Since 50% of the HCV patients were cured or deceased in the REACH-project, the number of current viremic HCV patients was estimated at 623 individuals in the Utrecht region (prevalence 0.05%). Conclusion The results of this study suggest a low ever-chronic and current HCV prevalence in the Utrecht area in the Netherlands, but other studies need to confirm this.

Abstract
Background: HIV infections are generally asymptomatic, leading to undetected infections and late-stage diagnoses. There are a lack of acceptable testing strategies for routine opt-out HIV screening. Our aim was to evaluate and compare the diagnostic yield of routine opt-out HIV testing strategies in two out-patient settings in a low HIV prevalence country: The public primary care and specialist out-patient care setting Methods: A cross-sectional study was conducted in a primary care clinic over a four-week period in 2016 to 2017 and in a specialist out-patient clinic over a concurrent 11-month period. Patients were invited to complete a questionnaire assessing demographic characteristics, acceptance of opt-out HIV testing as a policy in all out-patient clinics in Hong Kong and reasons if refusing the HIV test. All respondents were offered an HIV test. Results: This study included 648 and 1,603 patients in the primary care and specialist out-patient clinic, respectively. Test acceptability was 86 and 87% in the primary care and specialist out-patient setting, respectively. Test uptake was 35 and 68% in the primary care and specialist out-patient setting, respectively. No HIV infections were detected. Conclusion: Opt-out HIV testing during routine blood taking in the specialist out-patient setting achieved a high test uptake and acceptability. In contrast, opt-out HIV testing using rapid finger-prick tests in the primary care setting was not effective.

Retrieval and re-evaluation of previously diagnosed chronic hepatitis C infections lost to medical follow-up in the Netherlands. Eur J Gastroenterol Hepatol 2020; 32:851-856. [PMID: 31688310 DOI: 10.1097/meg.0000000000001593] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
OBJECTIVES Many individuals previously diagnosed with chronic hepatitis C virus (HCV) infection are likely to be lost to medical follow-up and, therefore, remain untreated despite new highly effective drug treatment, direct acting antivirals. We aim to identify and retrieve these chronic HCV-infected individuals to re-evaluate them and offer treatment. METHODS Possible chronic HCV infections were identified from test results of the medical microbiological laboratory, notifications to the public health service, and the hospital registries over the past 15 years were checked in South Limburg, the Netherlands. Individuals were contacted based on the physician-patient relationship of the gastroenterologist or microbiologist (retrieval). Individuals were informed about the new treatment options, offered an HCV-RNA test, and if still positive, referred to the gastroenterologist for treatment (re-evaluation). RESULTS In total, 689 individuals with a positive anti-HCV test in the past were identified, 308 (45%) were eligible for retrieval, 90 (29%) of them were retrieved, 34 (38%) of those retrieved were re-evaluated, 19 (56%) of those tested were HCV-RNA positive, and 12 (63%) of these individuals were offered treatment. CONCLUSION During every step of the retrieval chain, many patients were lost. Nevertheless, with substantial effort, we were able to identify, retrieve, and positively re-evaluate a limited number of individuals with a possible chronic HCV infection who were lost to medical follow-up (19 patients). With this case-finding approach, we were able to prevent potential severe complications in these patients and contribute to a small step in the eradication of HCV in the Netherlands.

Abstract
Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are usually asymptomatic for decades, thus targeted screening can prevent liver disease by timely diagnosis and linkage to care. More robust estimates of chronic HBV and HCV infections in the general population and risk groups are needed. Using a modified workbook method, the total number of ever chronically infected individuals in the Netherlands in 2016 was determined using population size and prevalence estimates from studies in the general and high-risk population. The estimated 2016 chronic HBV infection prevalence is 0.34% (low 0.22%, high 0.47%), corresponding to approximately 49 000 (low 31 000, high 66 000) HBV-infected individuals aged 15 years and older. The estimated ever-chronic HCV infection prevalence is 0.16% (low 0.06%, high 0.27%), corresponding to approximately 23 000 (low 8000, high 38 000) ever-chronic HCV-infected individuals. The prevalence of chronic HBV and HCV infections in the Netherlands is low. First-generation migrants account for most infections with 81% and 60% of chronic HBV and HCV infections, respectively. However, about one-fifth of HCV infections is found in the general population at low risk. This method can serve as an example for countries in need of more accurate prevalence estimates, to help the design and evaluation of prevention and control policies.

Screening for hepatitis C at the emergency department: Should babyboomers also be screened in Belgium? Liver Int 2019; 39:667-675. [PMID: 30525269 DOI: 10.1111/liv.14016] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 11/27/2018] [Accepted: 11/27/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS Patients are not screened adequately for hepatitis C virus infection in Belgium. In the USA, the Center for Disease Control recommends screening for patients born in the babyboom period (1945-1965). In Europe, the babyboom cohort was born between 1955 and 1974, but no screening policy has been targeted to this group. We aimed to study the prevalence of hepatitis C virus in an emergency department population in Belgium and the risk factors associated with hepatitis C virus infection. METHOD We performed a monocentric, cross-sectional seroprevalence study between January and November 2017 in a large Belgian non-university hospital. Patients aged 18-70 years presenting at the emergency department were eligible. Patients completed a risk assessment questionnaire and were screened for hepatitis C virus antibodies (Ab) with reflex hepatitis C virus ribonucleic acid testing. RESULTS Of 2970 patients, 2366 (79.7%) agreed to participate. hepatitis C virus Ab prevalence was 1.31%. Twenty-one (67.7%) hepatitis C virus Ab-positive patients were born between 1955 and 1974. With a previous treatment uptake of 54.5%, the prevalence of viremia was 0.9% in retrospect; 0.2% were newly diagnosed. The weighted multiple logistic regression model identified males born in the 1955-1974 cohort, intravenous drug use and high endemic birth country as significant risk factors for hepatitis C virus infection (P < 0.05). CONCLUSION Although the prevalence of hepatitis C virus Ab at the emergency department was higher than previously estimated for the general population in Belgium, the number of newly diagnosed patients with viremia was low. To optimize screening strategies, screening should be offered to males born in the 1955-1974 cohort, but especially in drug users, the prison population and immigrants from high endemic countries.

Abstract
BACKGROUND The Netherlands is one of the six European countries considered on track to eliminate hepatitis C virus by 2030. To achieve this goal, continuous efforts have to be put into designing efficient case-finding strategies, including the retrieval of previously diagnosed hepatitis C virus-infected who are lost to follow-up. AIMS To trace and treat all lost to follow-up hepatitis C virus patients in the Utrecht region and create an efficient retrieval strategy that can be used in future (national) retrieval initiatives. METHODS Positive hepatitis C virus diagnostic tests (anti-hepatitis C virus IgG or hepatitis C virus-RNA) from the laboratory of all four hospitals and one central laboratory for primary care diagnostics in the province of Utrecht from 2001 to 2015 were linked to clinical records. Untreated patients with available contact information were deemed eligible for retrieval and invited for reevaluation with (virology) blood tests, fibroscan measurement and possible direct-acting antiviral therapy. MAIN RESULTS After screening all hepatitis C virus diagnostics, 1913 chronic hepatitis C virus-infected were identified of which 14.1% (n = 269) were invited back into care. Overall, 17.4% was traced with the highest yield (28.3%) in those who lived in the Utrecht province. Through renewed patient assessments, 42 chronic hepatitis C virus infections were re-identified (76% with a history of intravenous drug use, 24% with Metavir F3-F4). Until now, 59% has either scheduled or initiated direct-acting antiviral therapy. CONCLUSION The retrieval of previously diagnosed hepatitis C virus patients through screening of laboratory diagnostics from the past is feasible and should be pursued for further control and reduction of hepatitis C virus infection. Retrieval is most successful when performed regionally. LAY SUMMARY To completely eliminate chronic hepatitis C virus (HCV) infection and prevent complications, undiagnosed and also previously diagnosed but lost to follow-up (LFU) HCV patients have to be brought (back) into care for therapy. Retrieval of LFU HCV patients through screening of laboratory diagnostics from the past is feasible and most successful when performed regionally.

Abstract
The Netherlands is striving to achieve national elimination of the hepatitis C virus (HCV) as one of the first countries worldwide. The favorable HCV epidemiology with both low prevalence and incidence, together with access to care and treatment, present excellent conditions to further build on towards this objective. The Dutch national plan on viral hepatitis, introduced in 2016, defines targets in the HCV healthcare cascade and provides a structural framework for the development of elimination activities. Since many different stakeholders are involved in HCV care in the Netherlands, focus has been placed on micro-elimination initiatives as a pragmatic and efficient approach. These numerous micro-eliminations projects have brought the Netherlands closer to HCV elimination. In the near future, efforts specifically have to be made in order to optimize case-finding strategies and to successfully accomplish the nationwide implementation of the registration and monitoring system of viral hepatitis mono-infections, before this final goal can be reached. The upcoming years will then elucidate if the Dutch' hands on approach has resulted in sufficient progress against HCV and if the Netherlands will lead the way towards nationwide HCV elimination.
