Abstract
BACKGROUND This study aimed to investigate the prevalence rate of hepatitis C virus (HCV) infection and identify the demographic, and sociological characteristics and changes in awareness of HCV infection by participating the study for North Korean defectors residing in South Korea. METHODS This study prospectively enrolled participants. Demographic, sociological and clinical data, and questionnaire surveys focused on awareness of HCV infection were collected. RESULTS In total, 211 North Korean defectors participated in this study from September 2020 until June 2021. There were 174 women (82.5%), and the overall mean age was 48.9 years (range, 20 to 80 years). Of these participants, 112 (53.1%) had immigrated to South Korea since 2011. The overall prevalence of anti-HCV antibody among North Korean defectors was 1.9%. Thirty participants (14.2%) had hepatitis B surface antigens. A huge lack of awareness regarding HCV infection has been observed among North Korean defectors. CONCLUSION This is the first prospective study to investigate the prevalence rate of HCV infection among North Korean defectors residing in South Korea. As North Korean defectors are a vulnerable group concerning HCV infection, they may benefit from HCV screening policies and educational interventions for HCV infection.

Circulating bile acid concentrations and non-alcoholic fatty liver disease in Guatemala. Aliment Pharmacol Ther 2022; 56:321-329.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a major liver disease worldwide. Bile acid dysregulation may be a key feature in its pathogenesis and progression. AIMS To characterise the relationship between bile acid levels and NAFLD at the population level METHODS: We conducted a cross-sectional study in Guatemala in 2016 to examine the prevalence of NAFLD. Participants (n = 415) completed questionnaires, donated blood samples and had a brief medical exam. NAFLD was determined by calculation of the fatty liver index. The levels of 15 circulating bile acids were determined by LC-MS/MS. Adjusted prevalence odds ratios (PORadj ) and 95% CI were calculated to examine the relationships between bile acid levels (in tertiles) and NAFLD. RESULTS Persons with NAFLD had significantly higher levels of the conjugated primary bile acids glycocholic acid (GCA) (PORadj T3 vs T1 = 1.85), taurocholic acid (TCA) (PORadj T3 vs T1 = 2.45) and taurochenodeoxycholic acid (TCDCA) (PORadj T3 vs T1 = 2.10), as well as significantly higher levels the unconjugated secondary bile acid, deoxycholic acid (DCA) (PORadj T3 vs T1 = 1.78) and its conjugated form, taurodeoxycholic acid (TDCA) (PORadj T3 vs T1 = 1.81). CONCLUSIONS The bile acid levels of persons with and without NAFLD differed significantly. Among persons with NAFLD, higher levels of the conjugated forms of CA (i.e. GCA, TCA) and the secondary bile acids that derive from CA (i.e. DCA, TDCA) may indicate there is hepatic overproduction of CA, which may affect the liver via aberrant signalling mediated by the bile acids.

Abstract
The adherence to the CDC guideline on screening non-U.S. born persons for hepatitis B virus infection was assessed. A retrospective cohort study was conducted at University of Washington primary care clinics using the electronic medical records. Persons from hepatitis B virus prevalent countries were identified using country of origin and language. Of 2329 eligible for screening, only 617 (26.5%) were screened. The prevalence of HBsAg was 35 (5.7%). Among women of reproductive age (18-44 years, n = 906), 238 (26.3%) were screened, and 7 (2.9%) were HBsAg positive. Low screening practice for chronic hepatitis B infection, and high infection prevalence among those screened was noted. The findings indicate that potentially three out of every one detected case may be missed. Urgent efforts are needed to scale up and consistently implement HBV screening at primary care clinics.

Abstract
BACKGROUND AND AIMS Metabolic conditions such as obesity, type 2 diabetes, metabolic syndrome, and nonalcoholic fatty liver disease (NAFLD) are highly prevalent in Guatemala and increase the risk for a number of disorders, including hepatocellular carcinoma (HCC). Aflatoxin B1 (AFB1) levels are also notably elevated in the population and are known to be associated with HCC risk. Whether AFB1 also contributes to the high prevalence of the metabolic disorders has not been previously examined. Therefore, the purpose of this study was to assess the association between AFB1 and the metabolic conditions. METHODS Four-hundred twenty-three individuals were included in the study, in which AFB1-albumin adduct levels were measured in sera. Metabolic conditions included diabetes, obesity, central obesity, metabolic syndrome, and NAFLD. Crude and adjusted prevalence odds ratios (PORs) and 95% confidence intervals (95% CI) were estimated for the associations between the metabolic conditions and AFB1-albumin adduct levels categorized into quartiles. RESULTS The study found a significant association between AFB1-albumin adduct levels and diabetes (Q4 vs Q1 POR = 3.74, 95%CI: 1.71-8.19; P-trend .003). No associations were observed between AFB1-albumin adduct levels and the other conditions. CONCLUSIONS As diabetes is the metabolic condition most consistently linked to HCC, the possible association between AFB1 exposure and diabetes may be of public health importance. Further studies are warranted to replicate the findings and examine potential mechanisms.

Abstract
Dental health workers (DHW) are at increased risk of acquiring occupational infections. Due to various protective measures, it can be assumed that infections have decreased over the past 14 years. Secondary data from a German accident insurance company was analyzed in terms of reported and confirmed occupational diseases (OD) in DHW from 2006 to 2019. A total of 271 claims were reported, of which 112 were confirmed as OD, representing an average of eight per year. However, the number of claims and confirmed ODs has decreased by 65.6% and 85.7%, respectively. The decrease was most evident for hepatitis B (HBV) and C (HCV) infections, while tuberculosis (TB) infections were stable. A total of 44 HCV, 33 HBV, 6 TB and 24 latent TB infections were confirmed as ODs. For DHW, 0.05, and for hospital workers, 0.48 claims per 1000 full-time equivalents (FTE) were registered in 2019. In a separate documentation system, between March 2020 and February 2021, 155 COVID-19 claims were registered, and 47 cases were confirmed as ODs. For DHW, 0.7, and for hospital workers, 47.3 COVID-19 claims per 1000 FTE were registered since 2020. Occupational infectious diseases rarely occur among DHW. Nevertheless, new infectious diseases such as COVID-19 pose a major challenge for DHW. Continued attention should be paid to infectious disease prevention.

Abstract
BACKGROUND Despite being considered as a low prevalence country for hepatitis B (HBV), some populations in Germany are at higher risk of infection. In the context of the World Health Organization's (WHO) viral hepatitis elimination goals, a valid epidemiological data base is needed to plan and monitor the national response. Prevention strategies include general and targeted HBV vaccination programmes. OBJECTIVE The aim of this work was to estimate the HBV vaccination coverage (VC) in the general population (GP) and different population groups in Germany from available evidence and to identify current evidence gaps for future research. METHODS We conducted a systematic review on HBV VC in the general population and populations at high risk of HBV exposure or severe infection in Germany. We included eligible publications (01/01/2017 to 06/06/2020) from databases Embase, Pubmed and Livivo, from a previous scoping review (including data published 01/01/2005-17/03/2017), from the national surveillance system and screened the reference lists of all publications at full text level. Risk of bias was assessed using the Hoy et al. tool. RESULTS We included 68 publications of 67 studies and assigned them to one or more suitable population groups. Twenty-one studies contained data among children/adolescents and three among adults from the GP (VC 65.8-90.5% and 22.9-52.1%, respectively), one among travelers (VC 89.0%), 13 among immunocompromised populations (VC 7.8-89.0%), 16 among populations with occupational risk and 16 with non-occupational risk of HBV exposure (VC 63.6-96.5% and 4.4-84.5%, respectively). CONCLUSION Comprehensive evidence at low risk of bias was identified for children/adolescents. However, 25 years after including HBV in the national immunisation schedule, VC in Germany is still below the 95%-goal defined by WHO. For people at occupational risk of HBV exposure, VC was mostly reported to be over the WHO goal of 80%, but quality of evidence was heterogenous and should be improved. For people at non-occupational risk of HBV exposure, evidence was sparse and of low quality. The low VC highlights the need for future research to plan vaccination programmes targeting these populations.

Abstract
Background Chronic active hepatitis C virus (HCV) infection is a major public health problem and causes liver fibrosis (LF) up to liver cirrhosis (LC). LF can be estimated by non-invasive, easy handling methods. With implementation of new HCV therapies, elimination rates of HCV are near 100%, resulting in less clinical complications and costs. The aim of our study was to evaluate the positive influence of HCV treatment on liver stiffness by non-invasive assessments of LF. Methods Sixty-two patients with HCV were treated with antiviral drug regimes. Serological fibrosis scores and ultrasound elastography (acoustic radiation force impulse and shear wave elasticity imaging (ARFI-SWEI)) were used for LF assessment on day 0 and 6 months after therapy. Results Antiviral treatment was successful in all cases. ARFI-SWEI measurements showed an improvement of all LF stages. Results of serological markers and scores were heterogeneous. Significant positive effects of treatment were seen for aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) scores, only. Further Pearson's coefficient showed moderate till very high correlations for ARFI-SWEI and FIB-4/APRI scores. Conclusion Today HCV therapy is able to cure HCV. Positive influences are improvement of LF stages. ARFI-SWEI, APRI and FIB-4 score are useful, easy handling tools to verify positive influence of HCV treatment on LF alone or in combination.

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
Viral hepatitis is a significant global health concern, particularly within low-middle income countries. Diseases historically affecting low-middle income countries, such as viral hepatitis, have become increasingly prevalent within high-income countries due to globalisation and mass international migration. High prevalence of viral hepatitis in migrant populations is of particular concern due to the associated morbidity and mortality, as well as the increased risk of vertical and horizontal transmission in the community. This is compounded by the asymptomatic nature of hepatitis, meaning many of those affected are unaware of their infection status. Long-term effects of viral hepatitis can include liver cirrhosis, liver cancer and liver failure. Therefore, the health needs of vulnerable migrants within high-income countries due to issues associated with viral hepatitis require attention. This includes assessment of measures such as targeted health education, increased screening, linkage to appropriate treatment and follow-up care. Additionally, it is necessary to address migrant healthcare barriers, such as language, economic and social barriers. It is imperative that vulnerable migrant groups gain appropriate access to health services to prevent disease transmission and the widening of health-related disparities within high-income countries.

Prevalence of Hepatitis B, C, and D in Germany: Results From a Scoping Review. Front Public Health 2020; 8:424. [PMID: 33014960 PMCID: PMC7493659 DOI: 10.3389/fpubh.2020.00424] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Accepted: 07/14/2020] [Indexed: 12/11/2022] Open
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.

[PMID: 32429964 PMCID: PMC7236441 DOI: 10.1186/s12889-020-08893-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Accepted: 05/11/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Currently, there is an increased flow of refugees into Ethiopia from neighboring countries. However, there are no post-arrival screening mechanisms for hepatitis B and C viruses which could be an additional burden for the local population. Hence, this study aimed to determine the prevalence and associated risk factors for hepatitis B and C viruses among refugees in Gambella, Ethiopia. It also aimed to determine the knowledge, attitude, and practice concerning hepatitis B and C viruses among participants. METHODS A cross-sectional study was conducted among 453 refugees in Gambella, Ethiopia from January until May 2018. A questionnaire was used to collect data on refugees' socio-demographic, risk factors, and KAP of hepatitis B and C infections. Five milliliters of blood sample were collected from each participant and the serum was used for HBsAg and anti-HCV antibody screening rapid tests. Positive samples were further tested by ELISA method. Data were performed using SPSS version 20, and a p-value less than 0.05 was considered statistically significant. RESULTS The overall prevalence of HBsAg and anti-HCV among refugees was 7.3% (33/453) and 2.0% (9/453) respectively. Of these, 6.8% (25/370) and 1.4% (5/370) of females were positive for HBsAg and anti-HCV, whereas 9.6% (8/83) and 4.8% (4/83) of males were positive for HBsAg and anti-HCV. The age group of 18-29 and 30-41 years old were related to HCV infection (P = 0.003 and P = 0.020). However, proposed risk factors were not related to HBV and HCV infections. Knowledge assessment showed that 86.5% (392/453) did not know how HBV and HCV infections are transmitted, and 86.8% (393/453) had no information about the availability of HBV vaccine. CONCLUSION This study showed intermediate prevalence of hepatitis B and hepatitis C virus in a large refugee camp in Ethiopia. The prevalence of hepatitis C virus was found to increase with age, but no other risk factor for either virus identified as significant. Refugees' understanding of hepatitis B and C was very limited. This indicates the need for screening policy to be implemented and integrated with other health services and awareness creation about the infection in all refugee camps of Gambella.

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 There are no data on the prevalence of non-alcoholic fatty liver disease (NAFLD) in general population samples in Guatemala or in other Central American countries. The prevalence and distribution of NAFLD and its associated risk factors were evaluated in a population-based sample of adults in Guatemala. METHODS Cross-sectional study of 411 men and women 40 years of age or older residing in urban and rural areas of Guatemala. Metabolic outcomes included obesity, central obesity, hypercholesterolemia, diabetes, and metabolic syndrome (MetS). Liver disease outcomes included elevated liver enzymes, elevated Fatty Liver Index (FLI), and elevated FIB-4 score. RESULTS The overall prevalence of obesity, central obesity, diabetes, and MetS were 30.9, 74.3, 21.6, and 64.2%, respectively. The fully-adjusted prevalence ratios (95% CI) for obesity, central obesity, diabetes, and MetS comparing women to men were 2.83 (1.86-4.30), 1.72 (1.46-2.02), 1.18 (1.03-1.34), and 1.87 (1.53-2.29), respectively. The overall prevalence of elevated liver enzymes (ALT or AST), elevated FLI, and elevated FIB-4 scores were 38.4, 60.1, and 4.1%, respectively. The fully-adjusted prevalence ratios (95% CI) for elevated liver enzymes (either ALT or AST) and elevated FLI score comparing women to men were 2.99 (1.84-4.86) and 1.47 (1.18-1.84), respectively. CONCLUSIONS The prevalence of metabolic abnormalities and liver outcomes in this general population study was very high. The prevalence of metabolic and liver abnormalities was particularly high among women, an observation that could explain the atypical 1:1 male to female ratio of liver cancer in Guatemala.

Effect of a Cooperation Strategy between Primary Care Physicians and Hospital Liver Units on HBV Care in Campania, Italy. Can J Gastroenterol Hepatol 2018; 2018:5670374.

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.

BMC Infect Dis 2018; 18:42. [PMID: 29338702 PMCID: PMC5771208 DOI: 10.1186/s12879-017-2908-5] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Accepted: 12/11/2017] [Indexed: 12/22/2022] Open
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.

Aflatoxin and viral hepatitis exposures in Guatemala: Molecular biomarkers reveal a unique profile of risk factors in a region of high liver cancer incidence. PLoS One 2017; 12:e0189255. [PMID: 29236788 PMCID: PMC5728519 DOI: 10.1371/journal.pone.0189255] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2017] [Accepted: 11/22/2017] [Indexed: 12/14/2022] Open
Abstract
Liver cancer is an emerging global health issue, with rising incidence in both the United States and the economically developing world. Although Guatemala experiences the highest rates of this disease in the Western hemisphere and a unique 1:1 distribution in men and women, few studies have focused on this population. Thus, we determined the prevalence and correlates of aflatoxin B1 (AFB1) exposure and hepatitis virus infection in Guatemalan adults. Healthy men and women aged ≥40 years (n = 461), residing in five departments of Guatemala, were enrolled in a cross-sectional study from May—October of 2016. Serum AFB1-albumin adducts were quantified using isotope dilution mass spectrometry. Multivariate linear regression was used to assess relationships between AFB1-albumin adduct levels and demographic factors. Biomarkers of hepatitis B virus and hepatitis C virus infection were assessed by immunoassay and analyzed by Fisher’s exact test. AFB1-albumin adducts were detected in 100% of participants, with a median of 8.4 pg/mg albumin (range, 0.2–814.8). Exposure was significantly higher (p<0.05) in male, rural, low-income, and less-educated participants than in female, urban, and higher socioeconomic status participants. Hepatitis B and C seropositivity was low (0.9% and 0.5%, respectively). Substantial AFB1 exposure exists in Guatemalan adults, concurrent with low prevalence of hepatitis virus seropositivity. Quantitatively, AFB1 exposures are similar to those previously found to increase risk for liver cancer in Asia and Africa. Mitigation of AFB1 exposure may reduce liver cancer incidence and mortality in Guatemala, warranting further investigation.

Abstract
An unprecedented rise in the number of asylum seekers and refugees was seen in Europe in 2015, and it seems that numbers are not going to be reduced considerably in 2016. Several studies have tried to estimate risk of infectious diseases associated with migration but only very rarely these studies make a distinction on reason for migration. In these studies, workers, students, and refugees who have moved to a foreign country are all taken to have the same disease epidemiology. A common disease epidemiology across very different migrant groups is unlikely, so in this review of infectious diseases in asylum seekers and refugees, we describe infectious disease prevalence in various types of migrants. We identified 51 studies eligible for inclusion. The highest infectious disease prevalence in refugee and asylum seeker populations have been reported for latent tuberculosis (9-45%), active tuberculosis (up to 11%), and hepatitis B (up to 12%). The same population had low prevalence of malaria (7%) and hepatitis C (up to 5%). There have been recent case reports from European countries of cutaneous diphtheria, louse-born relapsing fever, and shigella in the asylum-seeking and refugee population. The increased risk that refugees and asylum seekers have for infection with specific diseases can largely be attributed to poor living conditions during and after migration. Even though we see high transmission in the refugee populations, there is very little risk of spread to the autochthonous population. These findings support the efforts towards creating a common European standard for the health reception and reporting of asylum seekers and refugees.

Abstract
BACKGROUND Migration because of miscellaneous political crises in countries in the Middle East and Africa is a global challenge for whole Europe from an economic, social, and public health view. There is an urgent need to generate comprehensive, evidence-based data to expedite further screening and vaccination strategies. METHODS A total of 604 individuals ranging in age from 2 to 68 years who enrolled at a single reception center were tested for the prevalence of serologic markers for hepatitis virus types A, B, C, D, and E (HAV, HBV, HCV, HDV, HEV), respectively. RESULTS Anti-HAV antibody prevalence was 91.2 and 70.3% in children younger than 18 years of age. The prevalence of anti-HEV antibodies was 20.1% among the individuals. 3.0% were positive for hepatitis B surface antigen, whereas 15.2% tested positive for anti-hepatitis B core antigen. None of the refugees tested positive for anti-HDV. 14.1% of refugees were vaccinated against hepatitis B and had a protective anti-hepatitis B surface level of at least 10 mIU/ml. Significant differences in vaccination status were found between the regions (Eastern Mediterranean Region with 77/482 (16.0%; 95% confidence interval=12.7-19.3%) versus African Region with 1/55 (1.8%; 95% confidence interval=0-5.0%). The prevalence of anti-HCV antibodies was 1.2% (n=7), with 0.7% HCV RNA positivity; 16.7% of hepatitis B surface antigen-positive individuals were HCV coinfected (n=3). CONCLUSION The prevalence of refugees with previous exposure to hepatitis viruses was higher than that in the general German population, but lower than in other migrant populations in Germany. The vaccination status against hepatitis B was poor.

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
PURPOSE The prevalence of chronic hepatitis B virus- and hepatitis C virus-infections in the general German population has been estimated to be 0.6-0.7 and 0.3-0.4%, respectively. The population of Frankfurt/Main is multicultural and marked by different risks of chronic viral hepatitis. The aim of this prospective study was to define epidemiologic data for hepatitis B and C from consecutive patients of an interdisciplinary emergency unit in Frankfurt. PATIENTS AND METHODS Over a period of 12 months, 10 215 patients of an interdisciplinary emergency unit in Frankfurt/Main were screened for hepatitis B surface-antigen (HBsAg) and hepatitis C virus-antibodies (HCV-Ab). In case of positive HBsAg or HCV-Ab, a quantitative PCR analysis of virus was carried out. RESULTS The prevalence of HBsAg and HCV-Ab in the study population was 1.32% (n=135; group 1) and 2.70% (n=276; group 2), respectively, with a sex ratio close to 1. Quantitative PCR tests of virus load were performed in 72.59% (group 1) and in 82.61% (group 2), with confirmed viremia in 54.08% (group 1) and 41.67% (group 2), and correlated to elevated liver enzymes in 49.05% (group 1) and in 75.78% (group 2) of the cases. The ethnic distribution was 87.09% White (n=8897; group A) versus 12.90% other ethnic groups (n=1318; group B), with a prevalence of HBsAg-positive and HCV-Ab-positive cases of 1.08 and 2.76% (group A) and 2.96 and 2.28% (group B). CONCLUSION The results show that in multicultural areas, the prevalence of chronic viral hepatitis is increased. Because of the potential of progressive liver damage in viral hepatitis, field screening in specific populations at high risk for hepatitis should be performed.

Abstract
BACKGROUND Switzerland recommends individuals who originate from high-prevalence countries to be screened for hepatitis C virus (HCV) infection. However, not all these persons are equally at risk. We thus aimed to describe the number and characteristics of persons with HCV infection born outside of Switzerland. METHODS We compared characteristics of anti-HCV-positive individuals in the Swiss Hepatitis C Cohort Study (SCCS) and of HCV cases reported to the Federal Office of Public Health (FOPH), with those of the general population in Switzerland. Persons who inject drugs (PWID) and persons who do not inject drugs (non-PWID) were compared by age groups for different countries of origin (represented by ≥1% of participants in the SCCS or FOPH). RESULTS We included 4,199 persons from the SCCS and 26,610 cases from the FOPH. Both groups had similar characteristics. In both data sources non-PWID were more frequent in foreign-born than in Swiss-born persons (63% versus 34% in the SCCS). The only subgroup with a clearly higher proportion both in the SCCS and FOPH than in the general population were persons over 60 years from Italy and Spain, with a 3.7- and 2.8-fold increase in the SCCS. These persons were non-PWID (99%), less frequently HIV- and anti-HBc positive and more often female than PWID from Italy and Spain; cirrhosis at enrolment was frequent (31%). Their HCV genotypes were consistent with those observed in elderly non-PWID of their birth countries. In the FOPH a higher proportion than in the general population was also seen for cases from Georgia and Russia. CONCLUSION The identification of subgroups in which HCV infection is particularly frequent might allow for better targeting HCV screening among foreign-born persons in Switzerland and elsewhere.

Abstract
Viral hepatitis is a major public health problem affecting millions of people worldwide. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. The aim of the study was to assess outcomes and costs of treating patients with chronic hepatitis C in clinical practice in Germany. We carried out a prospective noninterventional study. Information on treatment outcomes, resource utilization and quality of life was provided by 281 physicians throughout Germany. Data of 3708 monoinfected HCV-patients treated between 2008 and 2011 were analysed. Therapy consisted of peginterferon/ribavirin. Mean age of patients was 43.7 years, 60.3% were male and estimated duration of infection was 13.6 years. Predominantly genotype 1 (61.3%) or 3 (28.5%) infections were observed. Sustained viral response (SVR)-rates in most frequently observed genotypes were 49.2% in GT-1 and 61.9% in GT-3 treatment-naive patients (Relapser: GT-1: 35.3% and GT-3: 57.3%; Nonresponder: GT-1: 25.0% and GT-3: 33.3%). Average treatment costs were lowest in treatment-naive patients (€18 965) and higher in patients who failed previous treatments (relapsers: €24 753; nonresponders: €19 511). Differences according to genotype were observed. Average costs per SVR in treatment-naive patients were €44 744 for GT-1 and €22 218 for GT-3. Treatment was associated with a decrease in quality of life; post-treatment quality of life was higher in patients achieving SVR. Our insight on real-life treatment outcomes and costs can serve as a reference for a comparison with other treatments. There is high need for short-term and long-term cost-effectiveness analysis in real-life settings as newly introduced treatment strategies with direct acting antivirals result in high SVR-rates but are more costly.
