[PMID: 39188540 PMCID: PMC11345383 DOI: 10.1016/j.jhepr.2024.101122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 05/13/2024] [Accepted: 05/21/2024] [Indexed: 08/28/2024] Open
Abstract
Background & Aims A goal of the World Health Organization's global hepatitis strategy is the elimination of chronic hepatitis C virus (HCV) infection by 2030. As part of its strategy, the Federal Joint Committee (Germany) decided to include hepatitis B and C screening in a preventive medical examination, which is performed at the primary care level in Germany. We investigated the results 1 year after implementation of screening between October 2021 and September 2022. Methods HBsAg/HBV DNA and anti-HCV/HCV RNA screenings were identified by billing categories in 286,192 individuals of 11 ambulatory healthcare centers. Results Compared to 30,106 HBsAg and 31,266 anti-HCV laboratory requisitions in the year 2018, the number of tests increased to 286,192 during the screening period. Compared to routine care, additional anti-HCV positive tests age dependently increased the tally by 98% (177 plus 170 positive cases in males) and 123% (96 plus 118 positive cases in females) in those aged 35-44 years up to 518% (17 plus 88 positive cases in males) and 514% (29 plus 149 positive cases in females) in those aged 75-84 years. Similar results were observed for HBsAg. Prevalences of HBsAg, anti-HCV and HCV RNA were 0.54%, 0.79% and 0.13%, respectively. Conclusions A structured hepatitis screening program at the primary care level has been successfully established and leads to age- and-sex-dependent large additional effects compared to routine care. Impact and implications Strategies to eliminate chronic hepatitis B and C virus infection are country specific and vary between clinical scenarios. Our analysis proves the efficacy of a screening program by primary care physicians compared to routine care in a low-prevalence country. This program should be accompanied by additional efforts in risk populations like people who inject drugs who are under-represented in the current screening approach.

Int J Ment Health Nurs 2024.

Abstract
Diagnostic overshadowing refers to a phenomenon whereby people with mental health conditions encounter inadequate or delayed medical attention and misdiagnosis. This occurs when physical symptoms are mistakenly attributed to their mental health condition. This paper presents a scoping review focusing on direct causes and background factors of diagnostic overshadowing in the context of hepatitis C infection in people who inject drugs and have concurrent mental health conditions. Despite significant strides in hepatitis C treatment with direct-acting antiviral drugs, the complex interplay of mental health conditions and physical symptoms necessitates a nuanced approach for accurate diagnosis and effective screening. This review was conducted using Joanna Briggs Institute's methodology for scoping reviews. The databases searched included Medline, Embase, PsycInfo, Global Health, CINAHL and Scopus. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The search strategies identified 1995 records. Overall, 166 studies were excluded. Forty-two (42) studies met the inclusion criteria. Three (n = 3) studies represented direct causes, and 39 (n = 39) with background factors related to diagnostic overshadowing. Studies highlighted six key themes encompassing diagnostic overshadowing, with communication barriers, stigma and knowledge deficiencies being the most prominent. Recognising and addressing diagnostic overshadowing in chronic hepatitis C will lead to increased screening, diagnosis and timely administration of life-saving antiviral therapy, resulting in profound enhancements in well-being and health outcomes. Moreover, this proactive approach will play a pivotal role in advancing the global effort towards eliminating hepatitis C by 2030.

Abstract
BACKGROUND AND AIMS Screening strategies for undiagnosed infections are fundamental for hepatitis C virus (HCV) elimination. We previously investigated HCV prevalence and screening strategies in an urban primary care setting. IV drug abuse, blood transfusion before 1992, immigration, or elevated ALT were identified as risk factors in a post hoc analysis and diagnosed 83% of unknown HCV-RNA-positive cases by screening only 26% of the population. We aimed to validate prospectively the proposed screening algorithm in two independent urban and rural cohorts and to analyse for potential differences. METHODS Anti-HCV and ALT were included in a routine check-up together with a questionnaire covering risk factors. HCV-RNA was analysed in anti-HCV-positive individuals. RESULTS In urban and rural areas, 4323 and 9321 individuals were recruited. The anti-HCV prevalence was 0.56% and 0.49%, and 0.1% of patients were HCV-RNA-positive in both regions. Fifty-two anti-HCV positive patients including eight HCV-RNA-positive cases were unaware of the infection (number needed to screen to detect one unknown anti-HCV-positive individual: 262). At least one of the three aforementioned risk factors or elevated serum ALT was present in 3000 patients (22%). Restricting HCV screening to only those with risk factors, 52% and 75% of all anti-HCV and HCV-RNA-positive undiagnosed patients were identified (number needed to screen: 111). CONCLUSIONS We confirm prospectively the efficiency of a risk-based HCV screening. The risk-based algorithm should be evaluated in other countries with similarly low HCV prevalence as in Germany to achieve WHO HCV elimination goals.

Abstract
Chronic hepatitis B virus (HBV) infection can lead to substantial morbidity and mortality. Although treatment is not considered curative, antiviral treatment, monitoring, and liver cancer surveillance can reduce morbidity and mortality. Effective vaccines to prevent hepatitis B are available. This report updates and expands CDC's previously published Recommendations for Identification and Public Health Management of Persons with Chronic Hepatitis B Virus Infection (MMWR Recomm Rep 2008;57[No. RR-8]) regarding screening for HBV infection in the United States. New recommendations include hepatitis B screening using three laboratory tests at least once during a lifetime for adults aged ≥18 years. The report also expands risk-based testing recommendations to include the following populations, activities, exposures, or conditions associated with increased risk for HBV infection: persons incarcerated or formerly incarcerated in a jail, prison, or other detention setting; persons with a history of sexually transmitted infections or multiple sex partners; and persons with a history of hepatitis C virus infection. In addition, to provide increased access to testing, anyone who requests HBV testing should receive it, regardless of disclosure of risk, because many persons might be reluctant to disclose stigmatizing risks.

Abstract
BACKGROUND The Dutch guideline for general practitioners (GPs) advises biannual surveillance of hepatitis B (HBV) patients and referral of every hepatitis C (HCV) patient. We aimed to study the prevalence, incidence, and the management of hepatitis B and C in primary care. METHODS This is a retrospective cohort study using the Rijnmond Primary Care database (RPCD), including health care data of medical records of GPs of approximately 200,000 patients in the area of Rotterdam, the Netherlands. Patient records were selected based on laboratory results, International Classification of Primary Care (ICPC) codes, and free-text words. RESULTS In total, 977 patients were included: 717 HBV, 252 HCV, and 8 HBV/HCV coinfected patients. Between 2013 and 2019, the prevalence of HBV and HCV declined from 5.21 to 2.99/1,000 person-years (PYs) and 1.50 to 0.70/1,000 PYs, respectively. We observed that the majority of the patients had been referred to a medical specialist at least once (71% HBV and 89% HCV patients). However, among chronic patients, we observed that 36.2% of the HBV patients did not receive adequate surveillance by their GP (≥2 alanine aminotransferase checks within 3 years) or a medical specialist. In addition, 44.4% of the HCV patients had no record about successful antiviral treatment. CONCLUSIONS This study demonstrated a declining prevalence in viral hepatitis B and C in primary care in the Netherlands. However, a substantial part of the patients did not receive adequate surveillance or antiviral therapy. It is therefore crucial to involve GPs in case finding and in follow-up after treatment.

Abstract
Since October 2021 in Germany all people with a statutory health insurance aged 35 and older have the right to be tested once for hepatitis B and C in a general preventative examination, regardless of specific risk-factors. This is a milestone on the way of eliminating these infections and also a great contribution to cancer prevention.In the USA the Centers of Disease Control and Prevention in April 2020 recommended a one-time screening for all adults aged 18 and older in addition to testing people with known risk-factors, because a significant part of the affected population cannot be identified with risk-based screening. Corresponding CDC-Recommendations for HBV are currently elaborated. According to available Data this screening strategy combined with a vaccination for HBV is necessary in Germany too to reach the agreed elimination goals till the year of 2030. Furthermore, an offer of such a testing for all adults can be regarded as ethically imperative to prevent as many life-threatening consequences or deaths as possible by effective therapies.

Abstract
BACKGROUND AND AIMS Pakistani migrants in Catalonia, Spain, could have high hepatitis C virus (HCV) prevalence. The aims of the HepClink study were (i) to implement and assess the quality of a micro-elimination strategy based on a community intervention and (ii) to obtain data from primary care (PC) registries as a baseline comparator. METHODS The community intervention targeted Pakistani adults and consisted of education, screening and simplified access to treatment. Quality indicators were calculated (effectiveness, impact and acceptability). The testing rate, the prevalence of HCV antibodies and HCV-RNA were compared with those observed in the Pakistani population accessing PC in the previous year. RESULTS A total of 505 participants were recruited through the community intervention (64.6% men, median 37 years) vs those accessing PC (N = 25 455, 70.9% men, median 38 years). Among study participants, 35.1% did not know about HCV and 9.7% had been previously tested. The testing rate in the community intervention was 99.4% vs 50.7% in PC. Prevalence was 4.6% vs 7.1% (p = .008) for HCV antibodies and 1.4% (3/6 new diagnoses) vs 2.4% (p = .183) for HCV-RNA. Among the six viremic patients, three began treatment within the intervention and two through the usual circuit and all completed the full course. CONCLUSIONS This novel community intervention was well accepted and effective at reaching a Pakistani migrant population with a low-level knowledge of HCV and largely not tested before. The observed prevalence and the high unawareness of their HCV status justify a targeted screening in this group both in the community and in PC.

Abstract
In 2014, an analysis was conducted to evaluate the hepatitis C virus (HCV) epidemiology and disease burden in Germany. Since then, there have been considerable developments in HCV management such as the implementation of direct acting antivirals. The aim of this analysis was to assess the recent data available for Germany, establish an updated 2020 HCV prevalence and cascade of care and evaluate the impact of what-if scenarios on the future burden of disease using modelling analysis. A dynamic Markov model was used to forecast the HCV disease burden in Germany. Model inputs were retrieved through literature review, unpublished sources and expert input. Next, three "what-if" scenarios were developed to evaluate the status quo, COVID-19 pandemic, and steps needed to achieve the WHO targets for elimination. At the beginning of 2020, there were 189,000 (95% UI: 76,700-295,000) viremic infections in Germany, a decline of more than 85,000 viremic infections since 2012. Annual treatment starts went down since 2015. Compared with 2019, the COVID-19 pandemic resulted in a further 11% decline in 2020. If this continues for two years, it could result in 110 excess HCC cases and 200 excess liver related deaths by 2030. To achieve the WHO targets, 81,200 people need to be diagnosed, with 118,600 initiated on treatment by 2030. This could also avert 1,020 deaths and 720 HCC cases between 2021 and 2030. Germany has made strides towards HCV elimination, but more efforts are needed to achieve the WHO targets by 2030.

Abstract
Since the advent of direct-acting antiviral therapy, the elimination of hepatitis c virus (HCV) as a public health concern is now possible. However, identification of those who remain undiagnosed, and re-engagement of those who are diagnosed but remain untreated, will be essential to achieve this. We examined the extent of HCV infection among individuals undergoing liver function tests (LFT) in primary care. Residual biochemistry samples for 6007 patients, who had venous blood collected in primary care for LFT between July 2016 and January 2017, were tested for HCV antibody. Through data linkage to national and sentinel HCV surveillance databases, we also examined the extent of diagnosed infection, attendance at specialist service and HCV treatment for those found to be HCV positive. Overall HCV antibody prevalence was 4.0% and highest for males (5.0%), those aged 37–50 years (6.2%), and with an ALT result of 70 or greater (7.1%). Of those testing positive, 68.9% had been diagnosed with HCV in the past, 84.9% before the study period. Most (92.5%) of those diagnosed with chronic infection had attended specialist liver services and while 67.7% had ever been treated only 38% had successfully cleared infection. More than half of HCV-positive people required assessment, and potentially treatment, for their HCV infection but were not engaged with services during the study period. LFT in primary care are a key opportunity to diagnose, re-diagnose and re-engage patients with HCV infection and highlight the importance of GPs in efforts to eliminate HCV as a public health concern.

From Screening to Therapy: Anti-HCV Screening and Linkage to Care in a Network of General Practitioners and a Private Gastroenterology Practice. Pathogens 2021; 10:pathogens10121570.

Abstract
(1) Background: Low rates of hepatitis C virus (HCV) diagnosis and sub-optimal linkage to care constitute barriers toward eliminating the infection. In 2012/2013, we showed that HCV screening in primary care detects unknown cases. However, hepatitis C patients may not receive further diagnostics and therapy because they drop out during the referral pathway to secondary care. Thus, we used an existing network of primary care physicians and a practice of gastroenterology to investigate the pathway from screening to therapy. (2) Methods: HCV screening was prospectively included in a routine check-up of primary care physicians who cooperated regularly with a private gastroenterology practice. Anti-HCV-positive patients were referred for further specialized diagnostics and treatment if indicated. (3) Results: Seventeen primary care practices screened 1875 patients. Twelve individuals were anti-HCV-positive (0.6%), six of them reported previous antiviral HCV therapy, and one untreated patient was HCV-RNA-positive (0.05% of the population). None of the 12 anti-HCV-positive cases showed up at the private gastroenterology practice. Further clinical details of the pathway from screening to therapy could not be analyzed. (4) Conclusions: The linkage between primary and secondary care appears to be problematic in the HCV setting even among cooperating partners, but robust conclusions require larger datasets.

Abstract
Linkage to care presents one obstacle toward eliminating HCV, and the current two-step pathway (anti-HCV, followed by HCV-RNA testing) results in the loss of patients. HCV screening was tested in the primary care setting with the fingerstick Xpert HCV viral load point-of-care assay to analyze the practicability of immediate diagnosis. Anti-HCV (Cobas) and HCV-RNA (Cobas Amplicor version 2.0, only performed if anti-HCV was positive) were analyzed centrally as the gold standard. The Xpert assay was performed by 10 primary care private practices. In total, 622 patients were recruited. Five individuals (0.8%) were anti-HCV positive, and one was HCV-RNA positive. The Xpert test was valid in 546/622 (87.8%) patients. It was negative in 544 and positive in 2 cases, both of whom were anti-HCV negative. The HCV-RNA PCR and the Xpert test were both negative in 4/5 anti-HCV-positive cases, and the individual with HCV-RNA 4.5 × 106 IU/mL was not detected by the Xpert test. Primary care physicians rated the Xpert test practicability as bad, satisfactory, or good in 6%, 13%, and 81%, respectively, though 14/29 (48%) bad test ratings were assigned by a single practice. Despite adequate acceptance, interpretability and diagnostic performance in primary care settings should be further evaluated before its use in HCV screening can be recommended.

Abstract
Background The PAGE-B score (Platelet Age GEnder–HBV) selects chronic hepatitis B (cHB) patients showing no relevant 5-year risk for hepatocellular carcinoma (HCC). We, therefore, explored potential cost reduction following the introduction of a PAGE-B tailored ultrasound screening in a single center cohort of cHB patients receiving stable antiviral therapy. Methods cHB patients attending throughout the year 2018 were documented. Patients eligible for PAGE-B score were classified into high (≥18 points), intermediate (10–17 points) and low (≤9 points) HCC risk groups. Patients of the low HCC risk group could postpone HCC screening to reduce HCC screening expenses. Full costs for hepatic ultrasound were assessed. Results Throughout the year cHB patients (n = 607) attended our clinic, which included PAGE-B eligible patients (n = 227, 37.4%) of whom n = 94 (15.8%) were allocated to the low HCC risk group. Sonographic HCC screening during a median exam time of 12.4 min (IQR 9.2–17.2) resulted in total costs of 22.82 Euro/exam. Additional opportunistic expenses caused by patient’s lost earnings or productivity were 15.6–17.5 €/exam and 26.7 €/exam, respectively. Following a PAGE-B tailored HCC screening at our institution annual full costs for cHB patients could be reduced by 15.51%, which equals a cost reduction by 1.91% for our total sonography unit. In comparison, 1.35% up to 7.65% of HBV-infected patients of Caucasian descent could postpone HCC screening according to population-based estimates from Germany. Conclusions PAGE-B risk score adapted screening for HCC is an efficient and cost neutral tool to reduce costs for sonography in Caucasian patients with chronic hepatitis B receiving antiviral treatment.

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.

Abstract
Hepatitis C virus (HCV) affects over 70 million people globally, with an estimated 399 000 HCV-related deaths in 2016. The World Health Organization (WHO) has set a goal to eliminate HCV by 2030. Despite the availability of direct-acting antivirals-highly effective and well-tolerated therapies for HCV-many patients infected with HCV in Germany have not initiated treatment, including a majority of those who are aware of their positive diagnosis. Barriers to screening, diagnosis, and treatment are major factors taking many countries off track for HCV elimination by 2030. Identifying country-specific barriers and challenges, particularly in at-risk populations such as people who inject drugs or men who have sex with men, has the potential to create tailored programs and strategies to increase access to screening or treatment and engage at-risk populations. This review aims to report the current steps toward HCV elimination in Germany, the country-specific barriers and challenges that will potentially prevent reaching the 2030 HCV elimination goal and describe good practice examples to overcome these barriers.

Abstract
BACKGROUND For treatment of genotype 1a (GT1a) infection with elbasvir/grazoprevir, the German guidelines recommend a differentiated approach depending on baseline viral load (BVL). For low BVL ≤800 000 IU/mL, treatment with 12 weeks elbasvir/grazoprevir should be considered, whereas for high BVL >800 000 IU/mL, this regimen is only recommended in nonstructural protein 5A (NS5A) resistance-associated substitutions (RAS) absence. With present NS5A RAS or when RAS-testing is not available, 16 weeks elbasvir/grazoprevir + ribavirin is preferred. Here, we investigated the adherence to these recommendations and the effectiveness of elbasvir/grazoprevir in a large German Hepatitis C-Registry GT1a cohort. METHODS From September 2016 until July 2018, 195 GT1a-infected patients were treated with elbasvir/grazoprevir ± ribavirin for 12-16 weeks. The primary outcome was per protocol SVR12 or SVR24. RESULTS Mean age was 50 years, 89% were male, 19% had cirrhosis, 72% were treatment-naïve. Forty-five percent had low BVL ≤800 000 IU/mL, 55% high BVL >800 000 IU/mL, of whom 49 vs. 42% were baseline RAS-tested. Four patients with high (7.7%) and two with low BVL (5%) had NS5A RAS of whom 50% received elbasvir/grazoprevir+ribavirin, respectively. Ninety-four percent of patients with low and 65% with high BVL received elbasvir/grazoprevir without ribavirin. Thirty-five percent of patients with high BVL received ribavirin, mostly without prior RAS-testing. Per protocol sustained virologic response (SVR) by low vs. high BVL was 98.8 and 95.1%. All patients with NS5A RAS achieved SVR. CONCLUSIONS In German, real-world most patients received elbasvir/grazoprevir without ribavirin. Ribavirin was mainly added in GT1a patients >800 000 IU/mL, who were not NS5A RAS tested. SVR rates were consistently high and comparable to clinical trial results.

Abstract
BACKGROUND Most studies estimate hepatitis C virus (HCV) disease prevalence from convenience samples. Consequently, screening policies may not include those at the highest risk for a new diagnosis. METHODS Clalit Health Services members aged 25-74 as of 31 December 2009 were included in the study. Rates of testing and new diagnoses of HCV were calculated, and potential risk groups were examined. RESULTS Of the 2 029 501 included members, those aged 45-54 and immigrants had lower rates of testing (12.5% and 15.6%, respectively), higher rates of testing positive (0.8% and 1.1%, respectively), as well as the highest rates of testing positive among tested (6.1% and 6.9%, respectively). DISCUSSION In this population-level study, groups more likely to test positive for HCV also had lower rates of testing. Policy makers and clinicians worldwide should consider creating screening policies using on population-based data to maximize the ability to detect and treat incident cases.

Abstract
Importance A 2014 review for the US Preventive Services Task Force (USPSTF) found antiviral therapy for hepatitis B virus (HBV) infection associated with improved intermediate outcomes, although evidence on clinical outcomes was limited. Objective To update the 2014 HBV screening review in nonpregnant adolescents and adults to inform the USPSTF. Data Sources Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Ovid MEDLINE (2014 to August 2019); with surveillance through July 24, 2020. Study Selection Randomized clinical trials (RCTs) on screening and antiviral therapy; cohort studies on screening, antiviral therapy clinical outcomes, and the association between achieving intermediate outcomes after antiviral therapy and clinical outcomes. Data Extraction and Synthesis One investigator abstracted data; a second investigator checked accuracy. Two investigators independently assessed study quality. Random-effects profile likelihood meta-analysis was performed. Results Thirty trials and 20 cohort studies, with a total of 94 168 participants, were included. No study directly evaluated the effects of screening for HBV infection vs no screening on clinical outcomes such as mortality, hepatocellular carcinoma, or cirrhosis. Screening strategies that focused on risk factors such as ever having immigrated from high-prevalence countries and demographic and behavioral risk factors would identify nearly all HBV infection cases. In 1 study (n = 21 008), only screening immigrants from high-prevalence countries would miss approximately two-thirds of infected persons. Based on 18 trials (n = 2972), antiviral therapy compared with placebo or no treatment was associated with greater likelihood of achieving intermediate outcomes, such as virologic suppression and hepatitis B e-antigen (HBeAg) or hepatitis B surface antigen loss or seroconversion; the numbers needed to treat ranged from 2.6 for virologic suppression to 17 for HBeAg seroconversion. Based on 12 trials (n = 4127), first-line antiviral therapies were at least as likely as nonpreferred therapies to achieve intermediate outcomes. Based on 16 trials (n = 4809), antiviral therapy might be associated with improved clinical outcomes, but data were sparse and imprecise. Nine cohort studies (n = 3893) indicated an association between achieving an intermediate outcome following antiviral therapy and improved clinical outcomes but were heterogeneous (hazard ratios ranged from 0.07 to 0.87). Antiviral therapy was associated with higher risk of withdrawal due to adverse events vs placebo or no antiviral therapy. Conclusions and Relevance There was no direct evidence for the clinical benefits and harms of HBV screening vs no screening. Antiviral therapy for HBV infection was associated with improved intermediate outcomes and may improve clinical outcomes.

Estimating the proportion of people with chronic hepatitis B virus infection eligible for hepatitis B antiviral treatment worldwide: a systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2020; 6:106-119. [PMID: 33197397 PMCID: PMC7801814 DOI: 10.1016/s2468-1253(20)30307-1] [Citation(s) in RCA: 87] [Impact Index Per Article: 21.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 09/08/2020] [Accepted: 09/17/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND In 2016, of the estimated 257 million people living with chronic hepatitis B virus (HBV) infection worldwide, only a small proportion was diagnosed and treated. The insufficiency of information on the proportion of people infected with HBV who are eligible for treatment limits the interpretation of global treatment coverage. We aimed to estimate the proportion of people with chronic HBV infection who were eligible for antiviral treatment worldwide, based on the WHO 2015 guidelines. METHODS In this systematic review and meta-analysis, we searched Medline, EMBASE, and the Cochrane databases from Jan 1, 2007, to Jan 31, 2018, for studies describing HBsAg-positive people in the population or health-care facilities. We extracted information from published studies using a standardised form to estimate the frequency of cirrhosis, abnormal alanine aminotransferase (ALT), HBV DNA exceeding 2000 IU/mL or 20 000 IU/mL, presence of HBeAg, and eligibility for treatment as per WHO and other guidelines as reported in the studies. We pooled proportions through meta-analysis with random effects. The study was registered with PROSPERO, CRD42020132345. FINDINGS Of the 13 497 studies, 162 were eligible and included in our analysis. These studies included 145 789 participants. The pooled estimate of the proportion of cirrhosis was 9% (95% CI 8-10), ranging from 6% (4-8) in community settings to 10% (9-11) in clinic settings. Examining the proportion of participants who had characteristics used to determine eligibility in the WHO guidelines, 1750 (10·1%) of 17 394 had HBV DNA exceeding 20 000 IU/mL, and 20 425 (30·8%) of 66 235 had ALT above the upper limit of normal. 32 studies reported eligibility for treatment according to WHO or any other guidelines, with a pooled estimate of eligibility at 19% (95% CI 18-20), ranging from 12% (6-18) for studies in community settings to 25% (19-30) in clinic settings. INTERPRETATION Many studies described people with HBV infection, but few reported information in a way that allowed assessment of eligibility for treatment. Although about one in ten of the 257 million people with HBV infection (26 million) might be in urgent need of treatment because of cirrhosis, a larger proportion (12-25%) is eligible for treatment in accordance with different guidelines. Future studies describing people with HBV infection should report on treatment eligibility, according to broadly agreed definitions. FUNDING WHO and US Centers for Disease Control and Prevention.

Abstract
BACKGROUND Infections during pregnancy are one of the leading causes of increased morbidity and mortality in mothers and their newborns worldwide. In Germany, there has been standardized healthcare for pregnancy for more than 50 years. The maternity guidelines of the Joint Federal Committee form the legal framework for this and include the screening of pregnant women for HIV, syphilis, and hepatitis B, among other things. AIM OF THE WORK The aim of this work is to determine the extent to which screening is covered by the German population. MATERIAL AND METHODS With the help of anonymized routine data of legally insured persons available to the Institut für angewandte Gesundheitsforschung Berlin GmbH (InGef) from 2011 to 2015, a definition of pregnancy was developed with the use of various ICD-10 and EBM codes and the first evaluation of the use of tests for infectious agents in pregnancy was carried out. RESULTS The high proportion of women who are tested for syphilis (95.3%) and hepatitis B (91.6%) during pregnancy indicates very good accessibility and use of prenatal screening services. For HIV, the proportion of women tested is significantly lower (84.9%). DISCUSSION Whether pregnant women refuse an HIV test, the test was performed elsewhere, or not recommended by the medical staff cannot be clarified on the basis of the available data. In view of the highly effective medical intervention options for syphilis, HIV, and hepatitis B, the aim should be to test pregnant women in Germany as completely as possible. The reasons for the lack of screening must be further investigated and starting points for increasing the use must be identified.

Abstract
Background: One of the five strategic directions in the World Health Organization global health sector strategy on viral hepatitis 2016-2021 is to generate strong strategic information for focused action to understand the viral hepatitis epidemic and focus the response. Knowledge of national prevalence is a cornerstone of strategic information. Germany is considered to be a low prevalence country for viral hepatitis B, C, and D, however the prevalence is likely to be higher among at-risk groups. Methods: The aim of this work was to give a detailed overview of the prevalence of viral hepatitis B (HBsAg, anti-HBc), C (anti-HCV, HCV RNA), and D (anti-HDV, HDV RNA) in different population groups in Germany. Therefore, we analyzed the results of a comprehensive literature search on various aspects of the epidemiological situation of hepatitis B, C, and D in Germany. Eligible publications including information on hepatitis B, C, and D prevalence were extracted from the overall spreadsheet table and summarized and analyzed based on virus and different population groups. A quality appraisal was performed using a checklist developed by Hoy et al. to assess risk of bias in prevalence studies. Results: Overall, 51 publications were identified through the literature search. The overall prevalence of HBsAg in the general (and proxy) population ranged from 0.3 to 1.6%. Among at-risk groups, including clinical populations and health care workers, the HBsAg prevalence ranged from 0.2% (among rheumatic patients) to 4.5% among HIV positive patients. The overall prevalence of anti-HCV in the general (and proxy) population ranged from 0.2 to 1.9%. Among at-risk groups, including clinical populations and health care workers, the anti-HCV prevalence ranged from 0.04% (among health care workers) to 68.0% among people who inject drugs. Conclusions: The hepatitis B and C prevalence in the general population in Germany is low. Prevalence is high to very high among at-risk populations, however for some groups evidence was incomplete or missing completely. To reach the elimination goals in Germany and implement a targeted response, more research among at-risk groups is needed.

The Causes for the Loss of Cellular Material at the Qualification Stage and the Influence of the Patient's Flora on Culture Infection. Transplant Proc 2020; 52:2231-2235.

Abstract
There are several causes leading to the loss of cellular material earmarked for transplantation. This paper aims to evaluate the number of lost donors and lost cells in the culture by means of verifying both the results of the qualification tests and the presence of microorganisms in the cellular material. The analysis involved 86 donors hospitalized for thermal burns, from whom cells were harvested for keratinocyte and fibroblast cultures in the years 2011 to 2015. All potential donors underwent qualification tests: Anti-HIV-1,2; HBsAg; Anti-HCV-Ab; HBc, and a specific test for syphilis. In the case of skin fragments collected for culturing, the microbiological tests included the carrying fluid, the medium after 1 change, and the medium during culturing and before transplantation. Skin donors for cell cultures were assigned to the groups based on if the skin was collected up to 7 days following the burn or later. On average, 12% of the disqualifications were reported among donors for cell culturing. The most frequent cause of donor disqualification (54% of all disqualifications) was a positive HBc(+). The occurrence of fungal infections detected in the cellular material was over 30%. Establishing the culture after day 7 following the injury immediately increases the risk of infection by 25% in comparison to those cultures established before or on day 7 following the injury. Proper disinfection of donor place is crucial, but sometimes insufficient for maintenance sterility in cell culture. The risk of infection increases 25% after 7 following the injury.

Abstract
BACKGROUND Germany is considered to be a low prevalence country for viral Hepatitis B, C and D (HBV, HCV, HDV). However, the burden of disease can be high among subpopulations. To meet the world Health Organization (WHO) viral hepatitis (VH) elimination goals, a national strategy was developed by the German government in 2016. We performed a scoping review to understand the baseline epidemiological situation in Germany regarding burden of disease, sequelae and care of HBV, HCV and HDV as a reference to monitor the progress of the national VH elimination and to identify further knowledge gaps and research needs. METHODS The protocol of the systematic review was prepared following the PRISMA statement guidelines for scoping reviews. Relevant search terms were used to identify eligible studies according to the research questions. We searched six online databases for original work published between January 2005 and March 2017. Based on the identified references, a matrix was developed presenting the eligible literature by targeted population group and outcome category. RESULTS 104 publications were eligible for extraction covering 299 outcome results. The population groups targeted in the identified studies included the general population and proxy populations, a range of clinical populations, people who inject drugs, men who have sex with men, healthcare workers, people in prisons and different migrant/mobile populations. Other vulnerable populations (e.g. sex workers) were not targeted. Overall, good evidence was found for HBV and HCV prevalence and HBV vaccination coverage in the GP and proxy populations. Evidence for these outcomes was weaker in populations at risk for VH. For HBV and HCV incidence and mortality, we identified large evidence gaps in all population groups. Outcomes on VH sequelae and care were mainly covered by studies in clinical populations of people living with viral hepatitis. For HDV the overall evidence available was scarce. CONCLUSIONS We created a comprehensive evidence-based overview on the current epidemiological situation of viral hepatitis in Germany. We identified knowledge gaps for further research and established a baseline for future monitoring of viral hepatitis elimination goals in Germany.

Abstract
BACKGROUND Chronic hepatitis C is a major public health burden. With new interferon-free direct-acting agents (showing sustained viral response rates of more than 98%), elimination of HCV seems feasible for the first time. However, as HCV infection often remains undiagnosed, screening is crucial for improving health outcomes of HCV-patients. Our aim was to assess the long-term cost-effectiveness of a nationwide screening strategy in Germany. METHODS We used a Markov cohort model to simulate disease progression and examine long-term population outcomes, HCV associated costs and cost-effectiveness of HCV screening. The model divides the total population into three subpopulations: general population (GEP), people who inject drugs (PWID) and HIV-infected men who have sex with men (MSM), with total infection numbers being highest in GEP, but new infections occurring only in PWIDs and MSM. The model compares four alternative screening strategies (no/basic/advanced/total screening) differing in participation and treatment rates. RESULTS Total number of HCV-infected patients declined from 275,000 in 2015 to between 125,000 (no screening) and 14,000 (total screening) in 2040. Similarly, lost quality adjusted life years (QALYs) were 320,000 QALYs lower, while costs were 2.4 billion EUR higher in total screening compared to no screening. While incremental cost-effectiveness ratio (ICER) increased sharply in GEP and MSM with more comprehensive strategies (30,000 EUR per QALY for total vs. advanced screening), ICER decreased in PWIDs (30 EUR per QALY for total vs. advanced screening). CONCLUSIONS Screening is key to have an efficient decline of the HCV-infected population in Germany. Recommendation for an overall population screening is to screen the total PWID subpopulation, and to apply less comprehensive advanced screening for MSM and GEP.

Abstract
The World Health Organization and the German government have announced an initiative to eliminate chronic hepatitis C until the year 2030. To reach this goal, one important step is adequate screening and detection of so far undiagnosed infections. The most common initial test is anti-HCV. This parameter was extra-budgetary reimbursed by statuary healthcare insurances in the past. However, this policy has changed after a nationwide laboratory reform which should reduce the laboratory costs of patients insured in the statuary healthcare insurances. We therefore analysed the impact of the laboratory reform on the order of anti-HCV tests in 510 656 anonymized patient data sets before and after the initiation of the reform. The number of anti-HCV tests declined by 9.4% in quarters I-III 2018 in comparison with the same time period of the year 2017. The number of HBsAg tests declined by 7.4%, indicating that the reduced anti-HCV laboratory orders are not parameter-specific, but most likely a surrogate of the intention of the laboratory reform to generally lower the demands of blood samples and laboratory costs. Thus, the scenario is an important example, how political decisions of the medical self-government influence the screening setting for viral hepatitis: if the current policy is not changed, the laboratory reform directly counteracts the WHO hepatitis C elimination strategy in Germany.

Abstract
OBJECTIVES Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) have a major impact on mortality worldwide. Although effective treatments are available for both HBV and HCV infection, <50% of the patients are even diagnosed in Belgium. This study assessed the real-life testing-and diagnosis rate by general practitioners (GPs) in Flanders, Belgium. SETTING We assessed the testing rate for HBV and HCV in 48 primary care practices with electronic medical records linked into one central registry in Flanders, Belgium. PARTICIPANTS The registry contains data of 440 140 patients over 20 years, which corresponds to 2.2% of the total Flemish population yearly. The primary care practices are distributed across Flanders and the patient population is representative for the distribution of age, gender and socioeconomic status at the community level. RESULTS Of 440 140 patients included in the registry, 7892 (1.8%) patients were screened for hepatitis B surface antigen (HBsAg) and 7206 (1.6%) for hepatitis C antibody (HCV Ab) of whom 369 (4.7%) and 163 (2.3%) tested positive, respectively. Of 14 059 patients with chronic liver enzyme elevation, 1112 (7.9%) and 1395 (9.9%) were tested for HBsAg and HCV Ab, respectively. There was no improvement in testing rates over time. CONCLUSIONS This study demonstrates that real-life testing uptake for viral hepatitis B and C is suboptimal in the general practices in Flanders, even in patients with chronically elevated liver enzymes. As GPs play a crucial role in prevention, diagnosis and linkage to care, efforts and strategies to increase the testing uptake for HBV and HCV are urgently needed.

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 AND AIM The hepatitis B virus (HBV) prevalence study performed in 2003 in Belgium is believed to be underestimating HBV prevalence due to underrepresentation of the non-Belgian population. Therefore, we assessed the prevalence and risk factors of HBV infection in a multi-ethnic region situated in Middle-Limburg Belgium, in 2017. METHODS Between May and November 2017, blood samples and questionnaires were taken from patients who presented at the emergency department of a large educational hospital. Blood samples were tested for hepatitis B surface antigen (HBsAg) and hepatitis B core antibodies (anti-HBc). A sample size of 1000 persons was required to obtain a representative sample of the general Middle-Limburg population. RESULTS Of the 1131 patients screened, the overall HBsAg prevalence was 0.97% with differences between Belgians (0.67%) and first-generation-migrants (2.55%), (P = 0.015). Five (45.5%) of 11 HBsAg-positive individuals were not aware of their HBV status. All five (100%) newly diagnosed HBsAg-positive patients had further clinical evaluation and all had a normal level of alanine aminotransferase (ALT). The prevalence of anti-HBc was 8.4%, and was significantly associated with age-gender-ethnicity interaction, presence of HBV-infected household member, hepatitis C virus infection, men who have sex with men, and hemodialysis. CONCLUSIONS In this area with large immigrant populations, we found a higher prevalence of HBV infection compared with the nationwide study of 2003. National HBV screening for first-generation migrants is needed as this high-risk group will go unnoticed due to the possible incorrect interpretation of normal ALT values.

Abstract
Background Chronic hepatitis C virus (HCV)-infection is a slowly debilitating and potentially fatal disease with a high estimated number of undiagnosed cases. Given the major advances in the treatment, detection of unreported infections is a consequential step for eliminating hepatitis C on a population basis. The prevalence of chronic hepatitis C is, however, low in most countries making mass screening neither cost effective nor practicable. Methods We used a Kohonen artificial neural network (ANN) to analyze socio-medical data of 1.8 million insurants for predictors of undiagnosed HCV infections. The data had to be anonymized due to ethical requirements. The network was trained with variables obtained from a subgroup of 2544 patients with confirmed hepatitis C-virus (HCV) infections excluding variables directly linked to the diagnosis of HCV. All analyses were performed using the data mining solution “RayQ”. Training results were visualized three-dimensionally and the distributions and characteristics of the clusters were explored within the map. Results All 2544 patients with confirmed chronic HCV diagnoses were localized in a clearly defined cluster within the Kohonen self-organizing map. An additional 2217 patients who had not been diagnosed with hepatitis C co-localized to the same cluster, indicating socio-medical similarities and a potentially elevated risk of infection. Several factors including, age, diagnosis codes and drug prescriptions acted only in conjunction as predictors of an elevated HCV risk. Conclusions This ANN approach may allow for a more efficient risk adapted HCV-screening. However, further validation of the prediction model is required.

Low hepatitis C prevalence in Belgium: implications for treatment reimbursement and scale up. BMC Public Health 2019; 19:39.

Abstract
Background Prevalence data of chronic hepatitis C virus (HCV) infection are needed to estimate the budgetary impact of reimbursement of direct-acting antivirals (DAAs). In Belgium, the restricted reimbursement criteria are mainly guided by regional seroprevalence estimates of 0.87% from 1993 to 1994. In this first Belgian nationwide HCV prevalence study, we set out to update the seroprevalence and prevalence of chronic HCV infection estimates in the Belgian general population in order to guide decisions on DAA reimbursement. Methods Residual sera were collected through clinical laboratories. We collected data on age, sex and district. HCV antibody status was determined with ELISA and confirmed with a line-immunoassay (LIA). In specimens with undetermined or positive LIA result, HCV viral load was measured. Specimens were classified seronegative, seropositive with resolved infection, indicative of chronic infection and with undetermined HCV status according to the test outcomes. Results were standardized for age, sex and population per district, and adjusted for clustered sampling. Results In total 3209 specimens, collected by 28 laboratories, were tested. HCV seropositivity in the Belgian general population was estimated to be 0.22% (95% CI: 0.09–0.54%), and prevalence of chronic HCV infection 0.12% (95% CI: 0.03–0.41). In individuals of 20 years and older, these estimates were 0.26% (95% CI: 0.10–0.64%) and 0.13% (95% CI: 0.04–0.43), respectively. Of the total estimated number of HCV seropositive individuals in Belgium, 66% were between 50 and 69 years old. Conclusions Prevalence of HCV seropositivity and chronic infection in the Belgian general population were low and comparable to many surrounding countries. These adjusted prevalences can help estimate the cost of reimbursement of DAAs and invite Belgian policy makers to accelerate the scaling up of reimbursement, giving all chronically infected HCV patients a more timely access to treatment.

Abstract
AIMS This study is aimed at assessing the efficacy of an active search and treat strategy for HBV-infected subjects in an endemic area (Campania, Italy). To do this, we created a cooperation bundle between 24 General Practitioners (GPs) and 3 Hospital Liver Units (HLU). We assessed whether this strategy improved the detection of HBV infection in patients at risk and the overall quality of care, with the aim of reducing liver disease progression. METHODS We estimated that, among about 20,000 patients cared for by the 24 GPs, approximately 280 patients unaware of or underestimating HBV infection would be found. Identified patients were to be referred to the HLU for clinical evaluation and treatment from February 2016 for 12 months. RESULTS Unexpectedly, screening and enrolment were poor (48 patients only). GP workloads, patient financial difficulties, and patients' refusal were the major causes of enrolment failure according to GPs. All patients referred to HLU completed the program; most of them were HBV inactive carriers. CONCLUSIONS This program failed to scavenge chronic HBV-infected patients in an endemic area and establish a successful clinical collaboration between GPs and HLU. Underlying reasons are diverse and call for new strategies to implement cooperation between primary care providers and hospital specialists.

Linkage to care of HbsAg-positive and anti-HCV-positive patients after a systematic screening approach in the German primary care setting. Eur J Gastroenterol Hepatol 2018; 30:280-283.

Abstract
BACKGROUND Identification of previously unknown cases is important to lower the burden of chronic hepatitis B and C infection. However, a screening program in the primary care setting has not yet been established. Therefore, a systematic screening project was conducted in 21 008 patients (Wolffram and colleagues). Here, we describe linkage to care of identified HbsAg-positive and anti-hepatitis C virus (HCV)-positive patients. METHODS General practitioners characterized further medical care by a standardized questionnaire. Data of 48/110 HbsAg-positive and 114/199 anti-HCV-positive patients were available. An APRI index more than 2 or up to 0.5 indicated the presence of cirrhosis or the absence of fibrosis. RESULTS APRI was calculated in 32/48 hepatitis B virus (HBV) patients (>2: n=1; ≤0.5: n=29) and 34/114 HCV patients (>2: n=4; ≤0.5: n=23). The general practitioners were already aware of the positive HBsAg and anti-HCV-test in 13/48 and 59/114 patients, respectively.For 29/35 newly diagnosed HBV patients and 26/55 HCV patients, further diagnostics were initiated: ultrasound 77 versus 38%, liver biopsy 20 versus 4%, and gastroscopy 20 versus 7%.Antiviral treatment was initiated in 5/35 HBV cases and in 10/55 HCV patients.A family screening was initiated in 22/35 HBV versus 13/55 HCV index patients and showed one additional HbsAg-positive and two anti-HCV-positive cases.Diagnostic procedures differed significantly between anti-HCV-positive and HbsAg-positive patients (P<0.001 for APRI, ultrasound, and family screening; P=0.03 for liver biopsy). CONCLUSION Diagnostic procedures should be improved for hepatitis C-infected patients. The APRI index was only of limited value in the primary care setting.

Abstract
Despite the availability of a preventive vaccine and active antiviral treatments that stop disease progression and reduce the risk of hepatocellular carcinoma, hepatitis B is still a major public health problem. Only an estimated 10% of the 257 million people living with HBV have been diagnosed and as few as 1% are being adequately treated. Barriers to diagnosis and treatment include: (i) limited awareness and lack of knowledge about HBV infection and HBV-related diseases; (ii) under-diagnosis with insufficient screening and referral to care; (iii) limited treatment due to drug availability, costs, reimbursement policies and the need for long-term or life-long therapy. These barriers and the actions needed to improve access to treatment are strongly influenced by the prevalence of infection and affect middle-high vs low-middle income countries differently, where most HBV carriers are found. In high-prevalence regions and low-to middle-income countries, the main challenges are availability and cost while in low-prevalence regions and middle-to high-income countries low screening rates, public awareness, social stigma and discrimination play an important role. Overcoming these challenges on a global scale is a complex clinical and public health challenge and multilateral commitment from pharmaceutical companies, governments, funders and the research community is lacking. The new WHO 2016 Global Health Sector Strategy on viral hepatitis targets testing and treatment, suggesting that important but strong actions are needed from advocacy groups, scientific societies and funding agencies to foster awareness and access to cure.

Abstract
Background Increasing the proportion diagnosed with and on treatment for chronic hepatitis C (CHC) is key to the elimination of hepatitis C in Europe. This study contributes to secondary prevention planning in the European Union/European Economic Area (EU/EEA) by estimating the number of CHC (anti-HCV positive and viraemic) cases among migrants living in the EU/EEA and born in endemic countries, defining the most affected migrant populations, and assessing whether country of birth prevalence is a reliable proxy for migrant prevalence. Methods Migrant country of birth and population size extracted from statistical databases and anti-HCV prevalence in countries of birth and in EU/EEA countries derived from a systematic literature search were used to estimate caseload among and most affected migrants. Reliability of country of birth prevalence as a proxy for migrant prevalence was assessed via a systematic literature search. Results Approximately 11% of the EU/EEA adult population is foreign-born, 79% of whom were born in endemic (anti-HCV prevalence ≥1%) countries. Anti-HCV/CHC prevalence in migrants from endemic countries residing in the EU/EEA is estimated at 2.3%/1.6%, corresponding to ~580,000 CHC infections or 14% of the CHC disease burden in the EU/EEA. The highest number of cases is found among migrants from Romania and Russia (50–60,000 cases each) and migrants from Italy, Morocco, Pakistan, Poland and Ukraine (25–35,000 cases each). Ten studies reporting prevalence in migrants in Europe were identified; in seven of these estimates, prevalence was comparable with the country of birth prevalence and in three estimates it was lower. Discussion Migrants are disproportionately affected by CHC, account for a considerable number of CHC infections in EU/EEA countries, and are an important population for targeted case finding and treatment. Limited data suggest that country of birth prevalence can be used as a proxy for the prevalence in migrants.

Abstract
OBJECTIVES Systematic screening for chronic hepatitis B and C does not yet exist in Germany. Therefore, the implementation of a screening approach within a preventive medical examination performed by primary care physicians ('Check-Up 35+') was evaluated in a recent prospective multicenter study. The present analysis estimates the financial consequences for the statutory health insurance by budget impact analysis. MATERIALS AND METHODS A Markov cohort model was developed consisting of 21 health states. Four different screening scenarios derived from the previous multicenter study were compared to usual care, a strategy without screening for hepatitis. Actual cost data for Germany were calculated and systematic literature searches for all input parameters were performed. RESULTS The base case results in incremental costs for the screening strategies compared to no hepatitis screening of 165-227 € per patient in a 20-year horizon. Two main parameters influence the financial consequences: (A) detection and treatment increase the costs in the beginning. (B) Screening avoids hepatitis induced end-stage liver disease. The initial higher costs exceed the later savings. Sensitivity analyses demonstrate a strong impact of medication costs for the treatment of additionally detected hepatitis infections on the outcome. This finding is robust to sensitivity analysis. CONCLUSIONS The screening strategy proposed here implies additional costs for the statutory health insurance, however, a decision regarding its usefulness must consider criteria other than cost. For example, the high burden of disease due to liver cirrhosis and liver carcinoma should be considered. Therefore, an additional cost-effectiveness-analysis should be conducted.

Abstract
Background To investigate access to treatment for chronic hepatitis B/C among six vulnerable patient/population groups at-risk of infection: undocumented migrants, asylum seekers, people without health insurance, people with state insurance, people who inject drugs (PWID) and people abusing alcohol. Methods An online survey among experts in gastroenterology, hepatology and infectious diseases in 2012 in six EU countries: Germany, Hungary, Italy, the Netherlands, Spain and the UK. A four-point ordinal scale measured access to treatment (no, some, significant or complete restriction). Results From 235 recipients, 64 responses were received (27%). Differences in access between and within countries were reported for all groups except people with state insurance. Most professionals, other than in Spain and Hungary, reported no or few restrictions for PWID. Significant/complete treatment restriction was reported for all groups by the majority in Hungary and Spain, while Italian respondents reported no/few restrictions. Significant/complete restriction was reported for undocumented migrants and people without health insurance in the UK and Spain. Opinion about undocumented migrants in Germany and the Netherlands was divergent. Conclusions Although effective chronic hepatitis B/C treatment exists, limited access among vulnerable patient populations was seen in all study countries. Discordance of opinion about restrictions within countries is seen, especially for groups for whom the health care system determines treatment access, such as undocumented migrants, asylum seekers and people without health insurance. This suggests low awareness, or lack, of entitlement guidance among clinicians. Expanding treatment access among risk groups will contribute to reducing chronic viral hepatitis-associated avoidable morbidity and mortality.

Abstract
This systematic review aimed at estimating chronic hepatitis B (HBV) and C virus (HCV) prevalence in the European Union (EU) and Economic Area (EEA) countries in the general population, blood donors and pregnant women. We searched PubMed©, Embase© and Cochrane Library databases for reports on HBV and HCV prevalence in the general population and pregnant women in EU/EEA countries published between 2005 and 2015. Council of Europe data were used for HBV and HCV blood donor prevalence. HBV general population estimates were available for 13 countries, ranging from 0·1% to 4·4%. HCV general population estimates were available for 13 countries, ranging from 0·1% to 5·9%. Based on general population and blood donor estimates, the overall HBV prevalence in the EU/EEA is estimated to be 0·9% (95% CI 0·7-1·2), corresponding to almost 4·7 million HBsAg-positive cases; and the overall HCV prevalence to be 1·1% (95% CI 0·9-1·4), equalling 5·6 million anti-HCV-positive cases. We found wide variation in HCV and HBV prevalence across EU/EEA countries for which estimates were available, as well as variability between groups often considered a proxy for the general population. Prevalence estimates are essential to inform policymaking and public health practice. Comparing to other regions globally, HBV and HCV prevalence in the EU/EEA is low.

Real-world treatment for chronic hepatitis C infection in Germany: Analyses from drug prescription data, 2010-2015. J Hepatol 2017; 67:15-22. [PMID: 28189752 DOI: 10.1016/j.jhep.2017.01.024] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2016] [Revised: 01/16/2017] [Accepted: 01/20/2017] [Indexed: 01/27/2023]
Abstract
BACKGROUND & AIMS Direct-acting antivirals (DAAs) for hepatitis C virus (HCV) have strongly improved treatment options since 2014, but it is unclear if treatment numbers have increased. We aimed to estimate the number of treatment regimens per month from 2010-2015 and the number of patients treated and cured with DAAs since 2014, as well as the associated costs. METHODS Drug prescription data of hepatitis C virus (HCV) antivirals for patients with statutory health insurance in Germany (∼85% of population) from January 2010-December 2015 were evaluated. Standard 28-day prescriptions of pegylated interferon (PegIFN) and 1st/2nd generation DAAs were combined according to treatment guidelines and analysed. Drug costs were calculated from pharmacy sales prices. Mean treatment durations/regimen from real-world data were used to calculate drug costs/regimen and numbers of DAA-treated persons in 2014/15. RESULTS From January 2010-December 2015 PegIFN/ribavirin-treatments/month decreased from ∼6500 to ∼650. Monthly HCV-prescriptions rose with the approval of 1st generation DAAs (2011), and decreased at the end of 2013. With the approval of 2nd generation DAAs, prescriptions/month increased (peak: ∼6600; March 2015), and subsequently decreased (∼4000; December 2015). In 2014, ∼7000 patients were treated with DAAs, and ∼20,100 in 2015. Treatment costs/month were stable at 12 million EUR (2010-2011), increased to ∼38 million EUR (March 2012), and peaked to 150 million EUR (March 2015). DAA-drug costs/year added up to ∼664million EUR (2014) and ∼1.3billion EUR (2015). CONCLUSIONS Despite an increase in DAA prescriptions, in December 2015 less persons/month were under treatment compared to January 2010, even though access to DAAs is not limited. However, yearly treatment numbers increased from 2014-2015. Under observed conditions, ∼18,000 patients/year can be cured, making substantial reduction of the estimated 160,000 diagnosed patients realizable. Political commitment to achieve further reduce DAA-prices and increase treatment numbers is recommended. LAY SUMMARY New treatment options with all-oral second generation direct-acting antivirals (DAAs) have resulted in the potential to cure chronic hepatitis C infection, but at high costs. Analyses from HCV drug prescription data of patients with statutory health insurance in Germany from 2010-2015, showed that DAAs replaced treatments with pegylated interferon and ribavirin, but accompanied by a disproportionate rise in costs. Although the monthly number of patients under treatment did not increase over time, the total number of patients yearly treated with DAAs increased from ∼7000 patients in 2014 to ∼20,100 in 2015, with a trend to shorter treatment regimens. Under observed conditions ∼18,000 patients can be cured yearly, making a substantial reduction of the estimated 160,000 diagnosed patients in Germany achievable.

Knowledge, Attitude, Behavior, and Practices Regarding HIV, Viral Hepatitis, and Sexually Transmitted Infections Among Migrants From Sub-Saharan Africa Living in Germany: A Multicenter Survey Protocol. JMIR Res Protoc 2017; 6:e80. [PMID: 28465279 PMCID: PMC5434255 DOI: 10.2196/resprot.6833] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 02/13/2017] [Accepted: 02/18/2017] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Migration has an impact on the epidemiology of viral hepatitis B and C (HEP) and HIV in Germany; migrants from sub-Saharan Africa (MisSA) in Germany are disproportionally affected by HIV. In the last 10 years, a total of 10%-15% of all newly diagnosed HIV cases were among MisSA; 20%-30% of them acquired HIV in Germany. Prevalence of HEP among MisSA in Germany is unknown, but Western Africa, from where most MisSA in Germany originate, reports the highest prevalence of hepatitis B worldwide. There is limited information on knowledge, attitudes, behaviors, and practices (KABP) regarding HIV, HEP, and sexually transmitted infections (STIs), as MisSA are not reached with surveys targeting the general population. OBJECTIVE Our objective was to determine the HIV, HEP, and STI information and prevention needs of MisSA in Germany. METHODS We conducted a multicenter, cross-sectional, KABP survey regarding HIV, HEP, and STIs among MisSA living in Germany using convenience sampling. The study design was developed as a community-based participatory health research (CBPHR) project; HIV/STI-prevention specialists, key persons from MisSA communities, and HIV/STI researchers were involved in all steps of the research process. Trained peer researchers recruited participants in six study cities. Potential modes of survey administration were interview or self-completion, and the questionnaire was available in English, French, and German. Questions on knowledge about HIV, HEP, and STIs were presented as true statements; participants were asked if they had known the information before. Focus groups with MisSA were conducted to interpret results. Data collection took place from October 2014 to November 2016. RESULTS Recruitment by peer researchers concluded with 3040 eligible participants. Data collection was completed in November 2016. We are currently analyzing the quantitative data and qualitative data from focus groups. We are conducting working group meetings to discuss the results in the respective study cities and to evaluate the application of participatory health research in epidemiological studies. First results are expected by the end of 2017. CONCLUSIONS Working with peer researchers to collect data allowed accessibility to a diverse sample of MisSA and, particularly, allowed us to reach vulnerable subgroups, such as MisSA without legal status. The ability to access hard-to-reach groups is one of the big advantages of CBPHR. The active inclusion of the persons under study in the design of the study resulted in higher acceptance and ownership of the research project in the target community; this ultimately lead to better quality of collected data. Furthermore, the participation of MisSA in the development of study design and data collection assures a better understanding of the interests, needs, and living conditions of this group.

Abstract
Chronic hepatitis C is curable disease. Low detection rate could be one of the reasons of poor treatment uptake. It is important to identify HCV prevalence and anti-hepatitis C virus (HCV) positive patients in population by effective screening strategy such as risk-based or birth cohort screening programs. There are no national population-based estimates of the HCV prevalence in the Czech Republic (CZ). The most recent seroprevalence survey determined a prevalence of positive anti-HCV antibodies of 0.2% (in 2001). The aim of the study was to determine the seroprevalence of HCV, HCV viraemia and HCV genotype in the CZ adult population. We also estimated the number of persons living with chronic hepatitis C in CZ. The examined group included 3000 adults, 18-90 years of age enrolled in 2015. All serum samples were examined to determined anti-HCV antibodies positivity, HCV-RNA positivity and genotypes. Of the 3000 samples, 50 were found to be anti-HCV-positive, for a seroprevalence of 1.67% (2.39% in males, 0.98% in females). The overall prevalence of positive HCV RNA was 0.93%: 1.5% in males, 0.39% in females. HCV genotype (GT) 1a was determined in 25%, GT 1b in 25% and GT 3a in 46%. Since 2001, the HCV seroprevalence has increased 8-fold. The highest HCV seroprevalence occurred in males aged 30-44 years. We can estimate that there are more than 140,000 people with HCV antibodies and more than 80,000 people with chronic hepatitis C living in the CZ. The introduction of birth cohort HCV screening could be beneficial for the country.

Abstract
BACKGROUND Today's highly efficacious, low-toxicity interferon-free treatment regimens for chronic hepatitis C virus (HCV) can cure most patients with HCV in 12-24 weeks. The aim of this study was to understand how the introduction of shorter duration treatment regimens for HCV will impact the capacity for treatment and value to society. METHODS A Markov model of HCV transmission and progression was constructed, incorporating nationally representative data on HCV prevalence, incidence and progression; mortality, treatment costs, medical expenditures, employment probabilities and disability payments in Germany. The model was stratified by HCV genotype and exposure route (1-time healthcare exposure, injection drug use and sexual activity). Treatment scenarios were based on German treatment guidelines and projected treatment capacity. The impact of different treatment scenarios on disease transmission and prevalence, quality-adjusted life years (QALYs), treatment costs, medical expenditures, employment and disability expenditures was calculated. RESULTS Depending on their adoption profile, new treatment regimens and protocols introduced over the next several years will increase HCV treatment capacity in Germany by 8-30%, reducing disease transmission and prevalence, increasing QALYs and adding €94-310 million in discounted social value (QALYs plus medical savings net of treatment costs) over a 30-year horizon. Additional social value in the form of higher employment and lower disability would also result. CONCLUSIONS The introduction of shorter HCV treatment regimens and the resulting increased treatment capacity in Germany would result in large gains to society by reducing disease transmission and prevalence, resulting in longer, healthier, more productive lives for current and future generations.

Abstract
Hepatitis C virus (HCV) is a hepatotropic RNA virus that causes progressive liver damage, which might result in liver cirrhosis and hepatocellular carcinoma. Globally, between 64 and 103 million people are chronically infected. Major risk factors for this blood-borne virus infection are unsafe injection drug use and unsterile medical procedures (iatrogenic infections) in countries with high HCV prevalence. Diagnostic procedures include serum HCV antibody testing, HCV RNA measurement, viral genotype and subtype determination and, lately, assessment of resistance-associated substitutions. Various direct-acting antiviral agents (DAAs) have become available, which target three proteins involved in crucial steps of the HCV life cycle: the NS3/4A protease, the NS5A protein and the RNA-dependent RNA polymerase NS5B protein. Combination of two or three of these DAAs can cure (defined as a sustained virological response 12 weeks after treatment) HCV infection in >90% of patients, including populations that have been difficult to treat in the past. As long as a prophylactic vaccine is not available, the HCV pandemic has to be controlled by treatment-as-prevention strategies, effective screening programmes and global access to treatment.

Language support for linguistic minority chronic hepatitis B/C patients: an exploratory study of availability and clinicians' perceptions of language barriers in six European countries. BMC Health Serv Res 2017; 17:150.

Abstract
Background Language support for linguistic minorities can improve patient safety, clinical outcomes and the quality of health care. Most chronic hepatitis B/C infections in Europe are detected among people born in endemic countries mostly in Africa, Asia and Central/Eastern Europe, groups that may experience language barriers when accessing health care services in their host countries. We investigated availability of interpreters and translated materials for linguistic minority hepatitis B/C patients. We also investigated clinicians’ agreement that language barriers are explanations of three scenarios: the low screening uptake of hepatitis B/C screening, the lack of screening in primary care, and why cases do not reach specialist care. Methods An online survey was developed, translated and sent to experts in five health care services involved in screening or treating viral hepatitis in six European countries: Germany, Hungary, Italy, the Netherlands, Spain and the United Kingdom (UK). The five areas of health care were: general practice/family medicine, antenatal care, health care for asylum seekers, sexual health and specialist secondary care. We measured availability using a three-point ordinal scale (‘very common’, ‘variable or not routine’ and ‘rarely or never’). We measured agreement using a five-point Likert scale. Results We received 238 responses (23% response rate, N = 1026) from representatives in each health care field in each country. Interpreters are common in the UK, the Netherlands and Spain but variable or rare in Germany, Hungary and Italy. Translated materials are rarely/never available in Hungary, Italy and Spain but commonly or variably available in the Netherlands, Germany and the UK. Differing levels of agreement that language barriers explain the three scenarios are seen across the countries. Professionals in countries with most infrequent availability (Hungary and Italy) disagree strongest that language barriers are explanations. Conclusions Our findings show pronounced differences between countries in availability of interpreters, differences that mirror socio-cultural value systems of ‘difference-sensitive’ and ‘difference-blindness’. Improved language support is needed given the complex natural history of hepatitis B/C, the recognised barriers to screening and care, and the large undiagnosed burden among (potentially) linguistic minority migrant groups.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) infections with genotype 2 (GT2) are generally considered as easy to treat. The current standard therapy is 12 weeks of sofosbuvir and ribavirin. However, sustained virological response (SVR) rates varied substantially in distinct subgroups. Therefore, re-assessing the efficacy of interferon-free therapy in cohorts with larger patient numbers is warranted. METHODS The German Hepatitis C registry is a national multicenter cohort. Patients are treated at the discretion of the physician. Data are collected by a web-based data system and confirmed by plausibility checks and on-site monitoring. RESULTS A total of 265 (4.3%) of 6034 patients enrolled in the registry were infected with GT2, and 236 had initiated treatment (60% males, 98% Caucasian, median age 54 years). Treatment with sofosbuvir and ribavirin for 12 weeks achieved SVR at week 12 post-treatment (SVR12) in 136/164 (83%) patients. SVR12 rates for this regimen were 80% (35/44) in treatment-experienced patients, 74% (20/27) in cirrhotics and 75% (21/28) in patients with HCV-RNA ≥6 million IU/mL. The overall SVR rate in patients treated with sofosbuvir/ribavirin 12 weeks per protocol (PP), excluding therapy discontinuation or lost to follow-up, was 135/151 (89%). PP SVR12 rates were 91% for treatment naïve, 83% for cirrhotic and 80% for treatment-experienced patients respectively. CONCLUSIONS In this large GT2 cohort, sofosbuvir and ribavirin for 12 weeks achieved lower SVR rates compared to treatment outcomes expected from phase 3 trials. These findings highlight the need for establishing alternative treatment strategies for GT2 patients, especially in patients with unfavourable outcome factors.

Abstract
Despite an available vaccine and efficient treatment for hepatitis B virus (HBV) infection, chronic HBV infection still remains a major global threat, and one of the top 20 causes of human mortality worldwide. One of the major challenges in controlling HBV infection is the high number of undiagnosed chronic carriers and the lack of access to prophylaxis and treatment in several parts of the world. We discuss relevant barriers that need to be overcome to achieve global control of HBV infection and make eradication possible. Most important, vaccination must be scaled-up to lower the risk of vertical transmission and decrease the number of new infections, and comprehensive screening programs must be linked to care to obtain a better rate of diagnosis and treatment. This can probably only be achieved if sustainable funding is available. We therefore emphasize the importance of making the management of viral hepatitis a global health priority.
