Abstract
Acute liver failure (ALF) is a rare condition with fatal outcome. Characteristic is rapid onset of liver damage without preexisting liver diseases, including hepatic encephalopathy and coagulopathy. Early and correct diagnosis is essential for further management of patients, since diagnosis impacts therapy choice. Survival of patients with ALF has improved dramatically due to advances in critical care medicine and the use of liver transplantation.

Abstract
Introduction German data regarding the burden of complications from chronic hepatitis C (CHC) virus infection are limited. To address this issue, this study evaluates the clinical and economic burden of hepatic and extrahepatic complications (EHCs) associated with CHC in Germany. Methods This retrospective, cross-sectional study used claims data from the Betriebskrankenkasse German sickness fund (2007–2014) to assess the risks and medical costs of hepatic complications and EHCs, including conditions that are prevalent and behavioral factors associated with CHC. Prevalence, incidence, and risks were calculated for 1:1 matched patients with and without CHC (n = 3994). All-cause cost, medical costs related to hepatic and EHCs, as well as CHC-related and non-CHC-related pharmacy costs (adjusted to the 2016 Euro rate), were calculated and compared between 1:5 matched patients with (n = 8425) and without CHC (n = 42,125). Results Patients with CHC had a 3-fold higher risk for any EHC (OR = 3.0; P < 0.05) and higher EHC-related medical costs (adjusted difference, €1606; P < 0.01) compared with patients without CHC. Total costs (€10,108 vs. €5430), hepatic complication-related medical costs (€1425 vs. €556), EHC-related costs (€3547 vs. €1921), CHC-related pharmacy costs (€577 vs. €116), and non-CHC-related pharmacy costs (€3719 vs. €1479) were all significantly greater for patients with CHC compared with patients without CHC. EHC-related medical costs were a major contributor to the higher all-cause medical (84.4%) and total (44.3%) cost differences between patients with CHC and the matched sample of patients without CHC. Conclusion CHC is associated with substantial clinical and economic burden in Germany, largely due to hepatic complications and EHCs. Funding Abbvie Inc.

Abstract
INTRODUCTION German data regarding the economic burden of chronic hepatitis C (CHC) and potential benefits of CHC treatment are limited. To address this issue, we evaluated the role of treatment in mitigating the economic burden of hepatic and extrahepatic complications (EHCs) from CHC virus infection in Germany. METHODS This retrospective, cross-sectional study used claims data from the Betriebskrankenkasse German sickness fund (2007-2014) to assess the medical costs of hepatic complications and EHCs, including conditions that are prevalent and behavioral factors associated with CHC. All-cause costs, medical costs related to hepatic and EHCs, and CHC-related and non-CHC-related pharmacy costs (adjusted to the 2016 euro rate) were calculated and compared between CHC patients' treated (n = 1714) and untreated time (n = 7124) and CHC patients that initiated treatment early (i.e., without cirrhosis; n = 1552) vs. late (i.e., with cirrhosis; n = 162). RESULTS CHC treatment was associated with an average adjusted savings of €1885 in annual all-cause medical costs per patient, with a significant proportion attributed to EHC-related cost savings (adjusted difference, €1363; P < 0.01). Although initiating CHC treatment early was economically beneficial compared with initiating treatment late, the total cost savings were not significantly different (annual average adjusted difference, €3831; P = 0.27). However, nearly 60% of these savings were EHC related (adjusted difference, €2255; P < 0.01). CONCLUSION CHC is associated with a significant economic burden in Germany, largely due to EHCs. Antiviral treatment may reduce the burden of CHC and result in significant cost savings, even when initiated at earlier stages of liver disease. FUNDING AbbVie Inc.

Abstract
The aim of the study was to evaluate the serological rate of Helicobacter pylori (H. pylori) infection in patients with chronic hepatitis C virus (HCV) infection and determine any correlations with liver damage and IL28B single-nucleotide polymorphism (SNP). One hundred eighty-nine patients with chronic HCV infection were included in the study, and H. pylori status was defined based on anti-H. pylori-IgG or anti-CagA-IgG antibodies using enzyme-linked immunosorbent assay (ELISA). Liver damage was assessed using histology or transient elastography. IL28B C/T polymorphism (rs12979860) was evaluated in circulating blood cells using a PCR-based restriction fragment length polymorphism assay. Overall H. pylori serology was positive in 38.1% of our HCV-infected subjects. Among those, the anti-CagA-IgG positivity rate was 43.1% and was within the range of previously described populations of the same region. Highest prevalence of H. pylori was found in patients between 31 and 40 years compared to other age subgroups. The seropositivity rate was higher in the non-cirrhotic group than the cirrhotic one (45.4% vs. 20.0%, p < 0.05). No difference was found in IL28B genotype between H. pylori-positive and -negative cohorts. However, we observed a trend for the lower anti-CagA-IgG expression level in relation to the IL28B T-allele. Our results do not support an association between HCV and H. pylori infection. Whether IL28B SNP has a functional role in modulation of serological response to H. pylori CagA needs further investigation.

Abstract
Background Potential risks for transfusion-transmissible infections are identified by donor history questionnaires (DHQs), and donors with higher risks are deferred from donation. We assessed to which extent the currently used DHQs support the identification of infections among blood donors. Methods Between 2006 and 2013, we analyzed data from notified HIV and HCV cases in the general population and positive blood donors in Germany. Logistic regressions were used to identify relevant infection risks. We estimated the possible effect of improved capture of risk factors for donor selection by calculation of population attributable fractions (PAF). Results Risky sexual contacts - MSM as well as heterosexual contacts - were the most prominent infection risks among HIV-infected donors. Whereas MSM contacts were significantly less reported by donors than by cases from the general population, 58% of donors disclosed heterosexual risks compared to 26% of notified cases. The complete identification of heterosexual risk contacts might prevent acceptance of 53% of HIV-infected donors. HCV-infected donors were more likely to report heterosexual exposure, imprisonment, and piercing/tattoo than notified HCV cases. Improved recording of piercing/tattoo could prevent acceptance of 16% of HCV-infected donors. Conclusion Donor selection should be improved with special attention to the identification of (hetero)sexual risk factors, invasive procedures (piercing/tattoo and imprisonment) applying well-designed DHQs, effective donor education, and confidential environment in all steps of the selection process.

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.

A large proportion of people who inject drugs are susceptible to hepatitis B: Results from a bio-behavioural study in eight German cities. Int J Infect Dis 2017; 66:5-13. [PMID: 29097248 DOI: 10.1016/j.ijid.2017.10.008] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2017] [Revised: 10/10/2017] [Accepted: 10/14/2017] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND People who inject drugs (PWID) are at high risk of hepatitis B virus (HBV) infection by sharing needles and drug use paraphernalia. In Germany, no routine surveillance of HBV prevalence and vaccination coverage among PWID exists. METHODS Socio-demographic and behavioural data were collected between 2011 and 2014 through face-to-face interviews, during a bio-behavioural survey of PWID recruited in eight German cities. Dried blood spots (DBS) prepared with capillary blood were tested for HBV markers. Factors associated with past/current HBV infection and vaccination status were analysed by univariable and multivariable analysis using logistic regression. The validity of self-reported HBV infection and vaccination status was analysed by comparison to the laboratory results. RESULTS Among 2077 participants, the prevalence of current HBV infection was 1.1%, of past HBV infection was 24%, and of vaccine-induced HBV antibodies was 32%. No detectable HBV antibodies were found in 43%. HBV infection status was significantly associated with study city, age, years of injecting, use of stimulants, migration status, and homelessness; HBV vaccination status was significantly associated with study city, age, and level of education. Correct infection status was reported by 71% and correct vaccination status by 45%. CONCLUSIONS HBV seroprevalence among PWID was about five times higher than in the general population in Germany, confirming PWID as an important risk group. Targeted information campaigns on HBV and HBV prevention for PWID and professionals in contact with PWID need to be intensified. Routinely offered HBV vaccination during imprisonment and opioid substitution therapy would likely improve vaccination rates among PWID.

Abstract
The spread of infectious diseases and vaccination history are common subjects of epidemiological and immunological research studies. Multiplexed serological assays are useful tools for assessing both current and previous infections as well as vaccination efficacy. We developed a serological multi-pathogen assay for hepatitis A, B and C virus, cytomegalovirus (CMV), Toxoplasma gondii, and Helicobacter pylori using a bead-based multiplex assay format. The multi-pathogen assay consisting of 15 antigens was utilized for the analysis of the serological response in elderly individuals of an influenza vaccination study (n = 34). The technical assay validation revealed a mean intra-assay precision of coefficient of variation (CV) = 3.2 ± 1.5% and a mean inter-assay precision of CV = 8.2 ± 5.3% across all 15 antigens and all tested samples, indicating a robust test system. Furthermore, the assay shows high sensitivities (ranging between 94% and 100%) and specificities (ranging between 93% and 100%) for the different pathogens. The highest seroprevalence rates in our cohort were observed for hepatitis A virus (HAV; 73.5%), followed by CMV (70.6%), T. gondii (67.6%) and H. pylori (32.4%). Seroprevalences for hepatitis B virus (HBV, 8.8%) and hepatitis C virus (HCV, 0%) were low. The seroprevalences observed in our study were similar to those from other population-based studies in Germany. In summary, we conclude that our multiplex serological assay represents a suitable tool for epidemiological studies.

Abstract
Hepatitis B virus (HBV) infection is a major health concern in developing countries that has a high morbidity and mortality rate. Vertical transmission of HBV from mother to child has been identified as a major factor leading to chronicity with attendant liver conditions, especially in poor socioeconomic settings. This study aims to evaluate the prevalence of serological HBV markers among pregnant women in Ibadan southwestern Nigeria and to determine the implications for perinatal HBV transmission. This study revealed the presence of varied HBV serological patterns of infection or immunity among pregnant women in Ibadan, Nigeria, and thus the risk of mother to child transmission.

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.

Abstract
Most of the European Union (EU) and European Economic Area (EEA) is considered a region of very low hepatitis A virus (HAV) endemicity; however, geographical differences exist. We did a systematic review with the aim of describing seroprevalence and susceptibility in the general population or special groups in the EU and EEA. We searched databases and public health national institutes websites for HAV seroprevalence records published between Jan 1, 1975, and June 30, 2014, with no language restrictions. An updated search was done on Aug 10, 2016. We defined seroprevalence profiles (very low, low, and intermediate) as the proportion of the population with age-specific anti-HAV antibodies at age 15 and 30 years, and susceptibility profiles (low, moderate, high, and very high) as the proportion of susceptible individuals at age 30 and 50 years. We included 228 studies from 28 of 31 EU and EEA countries. For the period 2000-14, 24 countries had a very low seroprevalence profile, compared with five in 1975-89. The susceptibility among adults ranged between low and very high and had a geographical gradient, with three countries in the low susceptibility category. Since 1975, EU and EEA countries have shown decreasing seropositivity; however, considerable regional variability exists. The main limitations of this study are that the studies retrieved for analysis might not be representative of all EU and EEA publications about HAV and might have poor national representativeness. A large proportion of EU and EEA residents are now susceptible to HAV infection. Our Review supports the need to reconsider specific prevention and control measures, to further decrease HAV circulation while providing protection against the infection in the EU and EEA, and could be used to inform susceptible travellers visiting EU and EEA countries with different HAV endemicity levels.

Abstract
AIM/OBJECTIVES/BACKGROUND Chronic hepatitis C (CHC) virus infection is a leading cause of liver-related morbidity and mortality. In Germany, as in many other countries, there is a lack of comprehensive epidemiological data. Routine data from sickness funds can support the estimation of the true prevalence and incidence of CHC. METHODS In this article, the results of annual and quarterly analyses of prevalence and incidence for the years 2007-2013 are presented using data of several German sickness funds. RESULTS Overall, the prevalence rate remained relatively stable at 0.2%, which is lower than the general assumption for Germany of 0.3%. CONCLUSION We found that despite the introduction of the breakthrough designated triple therapies with telaprevir or boceprevir in 2011, there was no increase of prevalence or incidence between 2010 and 2011.

[PMID: 28461903 PMCID: PMC5387957 DOI: 10.1136/bmjgast-2016-000130] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2016] [Revised: 02/07/2017] [Accepted: 02/14/2017] [Indexed: 12/16/2022] Open
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
BACKGROUND Infections with the hepatitis C virus (HCV) are a global public health problem. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. Newly introduced direct acting antivirals, especially interferon-free regimens, have improved rates of sustained viral response above 90% in most patient groups and allow treating patients who were ineligible for treatment in the past. These new regimens have replaced former treatment and are recommended by current guidelines. However, there is an ongoing discussion on high pharmaceutical prices. Our aim was to assess the long-term cost-effectiveness of treating hepatitis C genotype 1 patients with sofosbuvir/ledipasvir (SOF/LDV) treatment in Germany. MATERIAL AND METHODS We used a Markov cohort model to simulate disease progression and assess cost-effectiveness. The model calculates lifetime costs and outcomes (quality-adjusted life years, QALYs) of SOF/LDV and other strategies. Patients were stratified by treatment status (treatment-naive and treatment-experienced) and absence/presence of cirrhosis. Different treatment strategies were compared to prior standard of care. Sensitivity analyses were performed to evaluate model robustness. RESULTS Base-case analyses results show that in treatment-naive non-cirrhotic patients treatment with SOF/LDV dominates the prior standard of care (is more effective and less costly). In cirrhotic patients an incremental cost-effectiveness ratio (ICER) of 3,383 €/QALY was estimated. In treatment-experienced patients ICERs were 26,426 €/QALY and 1,397 €/QALY for treatment-naive and treatment-experienced patients, respectively. Robustness of results was confirmed in sensitivity analyses. CONCLUSIONS Our analysis shows that treatment with SOF/LDV is cost-effective compared to prior standard of care in all patient groups considering international costs per QALY thresholds.

Abstract
Background Hepatitis C infection is a global public health issue. Chronic hepatitis C infection is associated with significant morbidity and mortality. The aim of this study is to describe the costs for occupationally-cased hepatitis C infections based on data from an accident insurance carrier. Methods This study is a secondary analysis based on the Database of a German Institution for Statutory Accident Insurance. The analysis is based on a sample of insured parties whose hepatitis C infections were recorded as occupational diseases between 1996 and 2013. The analysis is based on recognised hepatitis C cases and incorporates records registered between 1 January 2000 and 31 December 2014. Results Within the study period, the number of reported and recognised hepatitis C cases declined by 73 and 86% respectively. The majority of recognised hepatitis C cases (n = 1.121) were female, older than 40 years and were active in a medical nursing profession. In the study period, the costs came to a total of € 87.9 million, of which 60% was attributable to pension payments (€ 51,570,830) and around 15% was attributable to pharmaceutical and medicinal products (€ 12,978,318). Expenses for drugs exhibited heavy increases in 2012 (from around € 500,000–800,000 to € 1.7 million) and 2014 (to € 2.5 million) in particular. Pension payments came to € 1.6 million in 2000 and rose continuously to over € 4 million in 2014. Expenses for occupational rehabilitation accounted for less than 1%. Conclusions For hepatitis C infections as an occupational disease, a considerable increase in costs has been observed in recent years, while the number of reports has declined heavily. This rise in costs is explained by the increase in pension payments and, since 2012, by a rise in the costs for drugs. The high costs of anti-viral therapies is offset by the potential for considerable treatment benefits. Healing the infection is expected to generate long-term cost savings for statutory accident insurance carriers, and also for social security systems.

High prevalence of chronic hepatitis B and C virus infection in a population of a German metropolitan area: a prospective survey including 10 215 patients of an interdisciplinary emergency unit. Eur J Gastroenterol Hepatol 2016; 28:1246-52.

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
This study aims to assess serostatus and vaccination status of hepatitis A and B among staff at schools for the handicapped. We also wanted to investigate factors associated with serostatus, number of infections with hepatitis A/hepatitis B at work, and factors influencing being vaccinated or not. The cross-sectional study was carried out between August 2010 and August 2012 at 13 German schools for severely handicapped. Data were analyzed using blood samples, vaccination documents, and questionnaires. A total of 395 persons participated in our study (response: 59.7%), information on 367 could be used for analysis. Two respondents have been infected with HAV at work, 53.4% were anti-HAV seropositive. Vaccination against hepatitis A was influenced by information about infectious diseases before starting to work, level of education, and marital status. One person got infected with hepatitis B during work, 53.2% were anti-HBs-seropositive. Vaccination against hepatitis B depended on perceived burden by nursing activities, and vaccination costs being paid by employer. Immunity to hepatitis A and B in our sample is insufficient and does not correspond to the infectious risks. Two persons got infected with hepatitis A and one person with hepatitis B during work at school, indicating an urgent need for preventive actions. J. Med.

High variability of HIV and HCV seroprevalence and risk behaviours among people who inject drugs: results from a cross-sectional study using respondent-driven sampling in eight German cities (2011-14). BMC Public Health 2016; 16:927. [PMID: 27595567 PMCID: PMC5011883 DOI: 10.1186/s12889-016-3545-4] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2016] [Accepted: 08/18/2016] [Indexed: 12/15/2022] Open
Abstract
Background People who inject drugs (PWID) are at increased risk of acquiring and transmitting HIV and Hepatitis C (HCV) due to sharing injection paraphernalia and unprotected sex. To generate seroprevalence data on HIV and HCV among PWID and related data on risk behaviour, a multicentre sero- and behavioural survey using respondent driven sampling (RDS) was conducted in eight German cities between 2011 and 2014. We also evaluated the feasibility and effectiveness of RDS for recruiting PWID in the study cities. Methods Eligible for participation were people who had injected drugs within the last 12 months, were 16 years or older, and who consumed in one of the study cities. Participants were recruited, using low-threshold drop-in facilities as study sites. Initial seeds were selected to represent various sub-groups of people who inject drugs (PWID). Participants completed a face-to-face interview with a structured questionnaire about socio-demographics, sexual and injecting risk behaviours, as well as the utilisation of health services. Capillary blood samples were collected as dried blood spots and were anonymously tested for serological and molecular markers of HIV and HCV. The results are shown as range of proportions (min. and max. values (%)) in the respective study cities. For evaluation of the sampling method we applied criteria from the STROBE guidelines. Results Overall, 2,077 PWID were recruited. The range of age medians was 29–41 years, 18.5–35.3 % of participants were female, and 9.2–30.6 % were foreign born. Median time span since first injection were 10–18 years. Injecting during the last 30 days was reported by 76.0–88.4 % of participants. Sharing needle/syringes (last 30 days) ranged between 4.7 and 22.3 %, while sharing unsterile paraphernalia (spoon, filter, water, last 30 days) was reported by 33.0–43.8 %. A majority of participants (72.8–85.8 %) reported incarceration at least once, and 17.8–39.8 % had injected while incarcerated. Between 30.8 and 66.2 % were currently in opioid substitution therapy. Unweighted HIV seroprevalence ranged from 0–9.1 %, HCV from 42.3–75.0 %, and HCV-RNA from 23.1–54.0 %. The implementation of RDS as a recruiting method in cooperation with low-threshold drop in facilities was well accepted by both staff and PWID. We reached our targeted sample size in seven of eight cities. Conclusions In the recruited sample of mostly current injectors with a long duration of injecting drug use, seroprevalence for HIV and HCV varied greatly between the city samples. HCV was endemic among participants in all city samples. Our results demonstrate the necessity of intensified prevention strategies for blood-borne infections among PWID in Germany.

Abstract
Background: Only limited data are available on the prevalence of hepatitis B in patients with proven rheumatic diseases and thus the risk of reactivation under immunosuppressive therapy. Objective: To analyse hepatitis B serology in patients with rheumatic diseases prior to therapy. Method: In total, 1,338 patient records were analysed for HBsAg, HBsAb and HBcAb in a cross-sectional, single-centre study between 2011 and 2015 at first presentation. Data acquisition was realized using electronic patient files created during routine care. The main variables considered as predictors for HBV reactivation included (i) the exact type of rheumatic disease and (ii) the therapeutically induced immunosuppression. Results: Overall, 5.9% of patients (n=79) had proven contact with hepatitis B (HBcAb positive), and HBsAb were not detected in 1.3% (n=18). The rate of vaccinated subjects was 7.8%. HBsAg was detected in 3 patients (0.2%). In addition, 70.3% of patients were treated during the course of rheumatologic disease previously or currently with glucocorticoids, 85.2% with disease-modifying anti-rheumatic drugs (DMARDs) and 20.1% with a biologic agent (e.g., anti-IL-6, anti-TNFalpha, anti-CD20, CTLA4Ig or anti-IL-12/23). Conclusion: Prevalence of hepatitis B serostatus in the analysed rheumatic patients regarding HBs-Ag and HBcAb with or without HBsAb prior to therapy does not differ from the data published for the general population in Germany. However, the rate of hepatitis B vaccinated patients was lower. In general, a significant portion of patients (5.9%) has been exposed to HBV and therefore exhibited an increased risk of reactivation of hepatitis B when undergoing immunosuppressive therapy.

Abstract
1 OBJECTIVE Chronic hepatitis C virus infections (HCV) cause a significant public health burden. Introduction of telaprevir (TVR) and boceprevir (BOC) has increased sustained virologic response rates (SVR) in genotype 1 patients but were accompanied by higher treatment costs and more side effects. Aim of the study was to assess outcomes and costs of treating HCV with TVR or BOC in routine care. 2 MATERIAL AND METHODS Data was obtained from a non-interventional study. This analysis relates on a subset of 1,786 patients for whom resource utilisation was documented. Sociodemografic and clinical parameters as well as resource utilisation were collected using a web-based data recording system. Costs were calculated using official remuneration schemes. 3 RESULTS Mean age of patients was 49.2 years, 58.6% were male. In treatment-naive patients SVR-rates of 62.2% and 55.7% for TVR and BOC were observed (prior relapser: 68.5% for TVR and 63.5% for BOC; prior non-responder: 45.6% for TVR and 39.1% for BOC). Treatment costs are dominated by costs for pharmaceuticals and range between €39,081 and €53,491. We calculated average costs per SVR of €81,347 (TVR) and €70,163 (BOC) in treatment-naive patients (prior relapser: 78,089 €/SVR for TVR and 82,077 €/SVR for BOC; prior non-responder: 116,509 €/SVR for TVR and 110,156 €/SVR for BOC). Quality of life data showed a considerable decrease during treatment. 4 CONCLUSION Our study is one of few investigating both, outcomes and costs, of treating HCV in a real-life setting. Data can serve as a reference in the discussion of increasing costs in recently introduced agents.

Abstract
BACKGROUND Germany is facing a huge humanitarian challenge with rapidly rising numbers of refugees entering the country. Data on hepatitis A seroprevalence and infection in refugees and asylum seekers in Europe during the current refugee exodus is scarce. OBJECTIVES To assess hepatitis A (HAV) seroprevalence and immunity in refugees arriving in northern Germany in 2015. MATERIALS AND METHODS A cross-sectional study of 235 refugees seeking shelter in reception centers in Northern Germany in August 2015 was performed, as acute Hepatitis A had been detected in one refugee in this camp. In order to analyze acute HAV infection and overall immunity, serological screening for HAV antibodies (combined IgG and IgM) was performed. The immunity threshold was defined as <20 IU/l. In all positive screening results, separate IgM testing was performed to detect acute infections. RESULTS Males accounted for 84.3 % of HAV screened refugees and the mean age of refugees was 29.1 ± 11.2 years. Children and adolescents below the age of 18 years made up 8.8 % of the migrants. Overall HAV immunity within the cohort was 90 %, and a mild age-dependent increase in HAV immunity was observed, with 81.1 % immunity in children <18 years and a 100 % seropositivity in subjects >50 years. One 20-year-old female refugee had positive IgM results with high HAV antibodies, most likely due to subacute HAV infection. CONCLUSIONS This comparably high rate of HAV protected refugees in our cohort supports the notion that the probability of large HAV outbreaks in current German refugee centers is low. However, depending on their current living situation, HAV vaccination should be considered for each refugee child, and healthcare providers and personnel working in refugee centers should be vaccinated against HAV.

Abstract
Das akute Leberversagen (ALV) ist ein seltenes, aber lebensbedrohliches Zustandsbild. Charakteristisch ist das rasche Auftreten eines schweren Leberschadens mit hepatozellulärer Nekrose und eingeschränkter Leberfunktion. Bei weiterhin hoher Mortalität ist ein frühzeitiges Erkennen und Einleiten einer ursachenspezifischen unterstützenden sowie v. a. intensivmedizinischen symptomatischen Therapie essenziell. Durch Fortschritte im Bereich der intensivmedizinischen Behandlung von Patienten mit akutem Leberversagen sowie der Lebertransplantation konnte das Überleben deutlich verbessert werden.

Abstract
BACKGROUND The performance of the multiplex Procleix Ultrio Elite assay as individual donor nucleic acid test (ID-NAT) for the detection of HIV-1, HIV-2, HCV, and HBV was evaluated in a retrospective, single center study. METHODS ID-NAT results of 21,181 blood donors, 984 tissue donors, 293 hematopoietic stem cell donors and 4 organ donors were reviewed in synopsis with results of serological screening and additional discriminatory and repetitive NAT in case of positive donors. RESULTS Specificity of the initial Procleix Ultrio Elite assay was 99.98% and after discriminatory testing 100.00%. Initially invalid results were observed in 75 of 21,181 blood donors (0.35%) but 16 of 984 tissue donors (1.62%, p < 0.001) which included non-heart-beating ('cadaveric') donors. All these had valid negative ID-NAT results after repeated testing or testing of 1:5 diluted specimens in case of tissue donors. Occult hepatitis B (defined here as HBV DNAemia without HBsAg detection) was demonstrated by ID-NAT in two anti-HBc-positive tissue donors and suspected in two other tissue donors, where a definite diagnosis was not achieved due to the insufficient sample volumes available. CONCLUSION The Procleix Ultrio Elite assay proved to be specific, robust and rapid. Therefore, routine ID-NAT may also be feasible for organ and granulocyte donors.

Abstract
Objectives Men who have sex with men (MSM) are at higher risk for coinfection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis than the general population. HIV infection and these coinfections accelerate disease progression reciprocally. This study evaluated the prevalence and incidence of these coinfections in HIV1-positive MSM in Germany. Materials and Methods As part of a nationwide, multicenter, prospective cohort study of HIV-infected MSM, plasma samples collected yearly were screened for HBsAg and antibodies to HBc, HBs, HCV, and syphilis. Samples with indications of active HBV or HCV infection were confirmed by polymerase chain reaction. Prevalence and incidence of each infection and incidence rates per study participant were calculated, and incidences over 4-year time intervals compared. Results This study screened 5,445 samples from 1,843 MSM. Median age at HIV seroconversion was 33 years. Prevalences of active, cleared, and occult HBV, and of active/cleared HCV were 1.7%, 27.1%, 0.2%, and 8.2%, respectively, and 47.5% had been effectively vaccinated against HBV. Prevalence of antibodies to Treponema pallidum and of triple or quadruple sexually transmitted infections (STIs) were 39.6% and 18.9%, respectively. Prevalence of STI, cleared HBV, HBV vaccination, and history of syphilis differed significantly among age groups. Incidences of HBV, HCV, and syphilis were 2.51, 1.54, and 4.06 per 100 person-years, respectively. Incidences of HCV and syphilis increased over time. HCV incidence was significantly higher in MSM coinfected with syphilis and living in Berlin, and syphilis incidence was significantly higher for MSM living in Berlin. Discussion Despite extensive HBV vaccination campaigns, fewer than 50% of screened MSM were effectively vaccinated, with a high proportion of HIV-positive MSM coinfected with HBV. High rates of STI coinfections in HIV-positive MSM and increasing incidences emphasize the need for better tailored campaigns for HBV vaccination and STI prevention.

Abstract
INTRODUCTION Hepatitis C is the second leading viral infectious disease worldwide. In Iran, hepatitis C is the most important and prevalent reason for chronic hepatitis and liver cirrhosis in the multi transfused population. AIM This study was conducted to determine seroprevalence and burden of hepatitis C in Chaharmahal and Bakhtiari province and to plan for controlling it. MATERIALS AND METHODS For this analytical, population-based study, 3000 samples were older than 15 years old and were enrolled from urban and rural areas of Chaharmahal and Bakhtiari province, southwest Iran per cluster sampling. Written informed consent was obtained from the participants and the demographic data, transmission route and risk factors were collected after blood sample taking. Hepatitis C virus antibody (HCV Ab) and western blotting were consecutively run. STATISTICAL ANALYSIS Data analysis was done by SPSS 19 using descriptive statistics, and chi-square test, Fisher's exact test, and logistic regression Ap value of 0.05 was considered as the level of significance. RESULTS The prevalence of HCV Ab was obtained 1.4% (95% CI, 0.95-1.7) and that of positive hepatitis C by western blotting 0.9% (95% CI, 0.65-1.3). The prevalence in men (1.2%) was obtained two times higher than women. The highest prevalence was obtained in 35 to 44-year-old population (2%). The prevalence was higher in married individuals and less in higher educated. History of hospital stay, first degree relatives infected with HCV, jaundice, history of blood transfusion, tattoo, outpatient surgery, imprisonment, contact with the infected, intravenous (IV) drug abuse, and smoking had significant association with disease prevalence (p<0.05). The highest odds ratio was obtained for history of IV drug abuse (OR=38.2, 95% CI, 14.06-103.9) followed by imprisonment (OR=8.9, 95% CI, 2.97-26.6). However, by logistic regression only history of IV drug abuse was obtained as significant (p<0.05). CONCLUSION Hepatitis C is growing and emerging as the most prevalent chronic, viral hepatic disease, so further consideration of risk factors and routes of transmission is crucial for appropriate planning for, and preventing, treating, and controlling hepatitis C. IV drug abusers as the most important group need special consideration and surveillance in order to cut infection chain and decrease the disease incidence.

Abstract
BACKGROUND Migrants from sub-Saharan Africa (MisSA) are a relevant sub-group for HIV-transmission in Germany. A total of 10-15 % of all newly diagnosed cases are MisSA, and approximately one third acquired HIV in Germany. There is limited information on knowledge, attitudes, behaviors and practices (KABP) regarding sexual health in African communities residing in Germany. METHODS From October-December 2013 we conducted a cross-sectional survey on KABP regarding HIV, viral hepatitis (HEP), and sexually transmitted infections (STI) among MisSA in Hamburg as a community-based participatory research project to identify knowledge gaps, sexual risk behavior regarding HIV/HEP/STI, HIV/STI-testing history and attitudes toward people living with HIV (PLWH). Trained peer researchers recruited participants through outreach. Questionnaires in German, English or French were either administered face-to-face or self-completed. Questions on knowledge about HIV/HEP/STI presented true statements; participants were asked if they knew the information before. To detect differences in sub-groups, unadjusted odds ratios (OR) were calculated, and a multivariate analysis for knowledge on HIV/HEP/STI was performed. RESULTS The final sample included 569 participants of whom 57 % were men. Most participants originated from Western and Central sub-Saharan Africa. Median time living in Germany was 6 years. Overall, 28 % had a university degree and 54 % reported a good level of German language. Over 80 % knew the risks for HIV transmission. A total of 44 % of respondents wrongly assumed that an HIV-diagnosis might lead to deportation and 64 % were not aware of the free and anonymous local HIV/STI-testing service. The proportion of participants with knowledge of presented facts on HEP varied from 40-58 %. The respective proportion on STI was 28-68 % and better among women compared to men (44 % vs. 54 %; OR = 1.45; 95 % CI 1.22-1.74). Men reported more often casual sex partners than women (43 % vs. 23 %; OR = 2.6; 95 % CI 1.7-4.0), and more frequently a previous STI (58 % vs. 39 %; OR = 2.1; 95 % CI 1.1-4.1). Overall, 16 % of women reported a history of sexual violence. The majority of respondents (75 %) reported that they would treat PLWH like any other person. CONCLUSION Study participants demonstrated good knowledge on HIV-transmission but knowledge gaps regarding HIV/STI-testing services, HEP and STI. This calls for targeted interventions providing more information about these topics in African communities in Hamburg and possibly also elsewhere.

Abstract
In September 2010, an outbreak of acute hepatitis B virus (HBV) infections in a nursing home was notified to public health authorities in Northern Germany. To identify the route of transmission and prevent further cases a retrospective cohort study was conducted. Blood samples of residents were tested for serologic markers of HBV infection and HBV subgenotypes and sequences were analyzed. Outbreak-related cases were defined as residents of the nursing home with detection of hepatitis B surface antigen (HBsAg) and the HBV DNA sequence of the outbreak strain in 2010. Information on possible risk factors as patient care, invasive diagnostic, and therapeutical procedures was collected using a standardized questionnaire. Risk ratios (RR) and 95% confidence intervals (CI) were estimated with exact Poisson regression and binomial regression. Sixty-four residents were included in the study, 5 of them were outbreak-related cases, 12 had a past HBV infection. The outbreak strain belonged to HBV genotype D2 (HBsAg subtype ayw3, Ala118) which is not prevalent in Germany but in Eastern Europe. All cases (median age 81) were female, had diabetes, blood glucose monitoring, and chiropody. In multivariable analysis only blood glucose monitoring was associated with HBV infection (RR = 22, 95%CI 3.0-∞). Blood glucose monitoring was reported to be done by nursing home staff with patient-based reusable lancet devices. In nursing home settings the use of single use lancets for blood glucose monitoring is recommended strongly to prevent transmission. National guidelines on the handling of point-of-care devices and reusable equipment in long-term care facilities should be developed.

Abstract
AIM: To evaluate the safety and efficacy of pegylated interferon alfa-2a and ribavirin therapy in elderly patients with chronic hepatitis C infection.
METHODS: Patients characteristics, treatment results and safety profiles of 4859 patients with hepatitis c virus (HCV) infection receiving treatment with pegylated interferon alfa-2a and ribavirin were retrieved from a large ongoing German multicentre non-interventional study. Recommended treatment duration was 24 wk for GT 2 and GT 3 infection and 48 wk for GT 1 and GT 4 infection. Patients were stratified according to age (< 60 years vs≥ 60 years). Because of limited numbers of liver biopsies for further assessment of liver fibrosis APRI (aspartate aminotransferase - platelet ratio index) was performed using pre-treatment laboratory data.
RESULTS: Out of 4859 treated HCV patients 301 (6.2%) were ≥ 60 years. There were more women (55.8% vs 34.2%, P < 0.001) and predominantly GT 1 (81.4% vs 57.3%, P < 0.001) infected patients in the group of patients aged ≥ 60 years and they presented more frequently with metabolic (17.6% vs 4.5%, P < 0.001) and cardiovascular comorbidities (32.6% vs 6.7%, P < 0.001) and significant fibrosis and cirrhosis (F3/4 31.1% vs 14.0%, P = 0.0003). Frequency of dose reduction and treatment discontinuation were significantly higher in elderly patients (30.9% vs 13.7%, P < 0.001 and 47.8% vs 30.8%, P < 0.001). Main reason for treatment discontinuation was “virological non-response” (26.6% vs 13.6%). Sustained virological response (SVR) rates showed an age related difference in patients with genotype 1 (23.7% vs 43.7%, P < 0.001) but not in genotype 2/3 infections (57.7% vs 64.6%, P = 0.341). By multivariate analysis, age and stage of liver disease were independent factors of SVR.
CONCLUSION: Elderly HCV patients differ in clinical characteristics and treatment outcome from younger patients and demand special attention from their practitioner.

Abstract
Background People who inject drugs are at high risk for hepatitis B, hepatitis C and HIV. HTLV was reported by neighboring countries to be prevalent in this population, but the situation for Germany is unclear. To generate seroprevalence and related behavioural data and to enhance prevention efforts against these infections for drug users in Germany, a multicentre sero- and behavioural survey was initiated. People who inject drugs are not well reached by services for testing and counselling for blood-borne infections in Germany. An interventional part of the study is intended to prove feasibility and acceptance of testing and counselling in low-threshold drop-in settings. Methods/Design Between May 2011 and March 2015, eligible participants (persons having injected drugs within the last 12 months, aged 16 years+, and living in the study city) are recruited by respondent driven sampling, using low-threshold drop-in facilities as study-sites in eight German cities with large drug scenes. Calculated sample size is 2,033 participants. Capillary blood samples collected as dried blood spots are anonymously tested for serological and molecular markers of hepatitis B and C, HIV, and HTLV I and II. A detailed face-to-face-interview about hepatitis- and HIV-related knowledge, former testing, imprisonment, sexual and injecting risk behaviour is conducted with participants. Staff is trained to offer pre- and post-test-counselling of blood-borne infections and HIV rapid testing to participants. Discussion We chose respondent driven sampling for recruitment of participants to improve representativeness of results. Persons, who are not reached by the facility where the study is conducted, are aimed to be included by recruitment through their personal social network of injecting drug users. To reduce differential biases in the questions on knowledge of transmission and prevention of infections, we present true statements on hepatitis B, C and HIV, their possible routes of transmission and measures of prevention to participants. Participants are told that the statements are true and are asked to answer if they knew this fact already or if it is new to them. In case of knowledge gaps they are offered free targeted counselling as well as free HIV rapid testing and post-test counselling of HIV and hepatitis test results.

Abstract
BACKGROUND & AIMS Detection of hepatitis C virus (HCV) RNA in peripheral blood mononuclear cells (PBMC) and/or hepatocytes in absence of HCV RNA in serum, designated as 'occult HCV infection', has been a matter of controversy in recent years. We investigated for the first time the prevalence of occult HCV infection in large cohorts of chronic hemodialysis (CHD) and kidney transplant (KTx) patients. METHODS We enrolled 417 CHD patients, 417 KTx recipients and 2 control groups - 25 anti-HCV (antibody against HCV)-positive and HCV RNA-positive patients with chronic hepatitis C, and 40 anti-HCV-, HCV RNA-, and HBsAg-negative healthy subjects. HCV RNA was tested in serum and PBMC using a sensitive commercial assay. RESULTS In CHD patients, the prevalence of anti-HCV was 3.6% (15/417) and of positive serum HCV RNA 2.4% (10/417). HCV RNA was detected in PBMC in 1/407 (0.25%) HCV serum RNA-negative patients ("occult HCV infection"). In KTx recipients, prevalence of anti-HCV was 4.8% (20/417) and of positive serum HCV RNA 4.6% (19/417). Occult HCV infection was found in 2/398 (0.5%) serum HCV RNA-negative patients. On a mean longitudinal follow-up of 30months of the 3 patients with occult HCV infection, there was no clinical or virological evidence of HCV infection. CONCLUSIONS The prevalence of occult HCV infection was very low in our CHD and KTx patients, and it did not appear to be clinically relevant. Further studies in geographic populations with high HCV endemicity are required to clarify the significance of occult HCV infection in these patient groups.
