Abstract
In endemic areas, hepatitis C virus (HCV)/hepatitis B virus (HBV) coinfection is common, and patients with coinfection have a higher risk of developing liver disease such as hepatocellular carcinoma, liver fibrosis and cirrhosis. In such cases, HCV predominates, and HBV replication is suppressed by HCV. HCV core proteins and interferons that are activated by HCV are responsible for the suppression of HBV. Immunosuppression is also seen in patients with HCV and HBV coinfections. A decrease in HCV-neutralizing antibody response and circulation of Th1-like Tfh cells is observed in patients with HCV and HBV coinfection. Both viruses interacted in the liver, and treatment of HCV/HBV coinfection is genotype-based and complex due to the interaction of both viruses. In HCV-dominant cases, direct-acting antiviral drugs and peg interferon plus ribavirin are used for the treatment, with continuous monitoring of AST and ALT. HBV-dominant cases are less common and are treated with peg interferon and nucleoside nucleotide analogues with monitoring of AST and ALT. The SVR rate in HCV-HBV coinfection is higher than that in monoinfection when treated with direct-acting antiviral drugs. But there is a risk of reactivation of HBV during and after therapy. The rate of reactivation is lower in patients treated with direct-acting antiviral drugs as compared to those treated with peg interferon plus ribavirin. Biomarkers of HBV such as HBcrAg, HBV DNA and HBVpg RNA are not effective in the prediction of HBV reactivation; only the hepatitis B surface antigen titre can be used as a biomarker for HBV reactivation. HCV can also be reactive, but this is found in very rare cases in which HBV is present and is treated first.

Confirmation of guideline-defined hepatitis C screening strategies within the 'Check-Up35+' examination in the primary care setting. Liver Int 2023; 43:785-793.

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

Abstract
ZusammenfassungZur Behandlung der chronischen Hepatitis C wurden in den letzten Jahren direkt wirkende antivirale Medikamente (DAA) zugelassen und sind bei Erwachsenen etabliert. Sie machten die interferonbasierten Therapien obsolet. Auch für Kinder und Jugendliche stehen seit Kurzem einige DAA zur Verfügung, die überwiegend ab dem Alter von 3 Jahren eingesetzt werden können.Die chronische Hepatitis C wird bei Kindern überwiegend vertikal übertragen und ist selten. Sie ist zwar zunächst eine wenig aktive und progrediente Erkrankung, kann aber im Erwachsenenalter in eine Leberzirrhose mit der Folge eines hepatozellulären Karzinoms übergehen. Die Diagnose ist mit der Bestimmung des Anti-HCV (IgM/IgG) und der HCV-RNA im Serum mit Genotypisierung leicht zu stellen. Die DAA werden oral appliziert und ausgesprochen gut toleriert. Drei Wirkstoffkombinationen stehen aktuell zur Verfügung, und 2021 wird eine weitere zugelassen. Die Heilungschancen sind mit über 95 % ausgesprochen gut und anhaltend.Im eigenen Krankengut wurden 25 Jungen und Mädchen überwiegend mit Genotyp 1 im Alter von 4 bis 17 Jahren mit DAA behandelt. Unabhängig von der Höhe der HCV-RNA im Serum waren alle bereits nach 4 Wochen HCV-RNA negativ und erzielten einen dauerhaften Erfolg.Die wesentliche Aufgabe ist nun, alle Kinder und Jugendlichen mit einer chronischen Hepatitis C zu identifizieren. Bei der äußerst guten Heilungschance kann davon ausgegangen werden, dass das Eradikationsziel in dieser Altersgruppe in absehbarer Zeit erreicht werden kann.

Abstract
Background and objectives Chronic liver disease (CLD) encompasses a variety of etiologies, and the infectious causes are mainly hepatitis B and hepatitis C virus. Chronic alcohol abuse and non-alcoholic fatty liver disease also have a major contribution to CLD. The Child-Pugh scoring system indicates the probable prognosis and mortality risk of a patient with cirrhosis. The primary objective of this research is to observe the mortality risks of CLD caused by a variety of etiologies mentioned above. The secondary objective is to determine the biochemical markers that are correlating with the severity of the study groups. Another aim was to determine the Model for End-Stage Liver Disease (MELD) scoring of each study group predicting the severity of disease among the Child-Pugh classification. Materials and methods We broadly classified the etiologies into two study groups: (1) hepatitis B, C associated CLD (hepatitis B, C-CLD) and (2) non-hepatitis B, C associated CLD (non-hepatitis B, C-CLD). This study was conducted as a descriptive, retrospective study involving patients admitted to the Gastroenterology Department at Dow University Hospital between July 2019 and December 2019. All patients who met the inclusion criteria were included in the study in order to document their levels of severity markers of CLD. A total of 167 individuals met the inclusion criteria, and the sampling was done through non-probability consecutive methods. All continuous variables were described as mean and standard deviations, which were then compared using an independent sample t-test. The comparison of categorical data was done either using the chi-square test or Fisher’s exact test accordingly. A p-value of <0.05 was considered statistically significant (two-tailed). Results The mean age of the study population was 51.83 ± 13.67, with no difference in gender and type of CLD. The frequent co-morbidities (other than CLD) found in the study population were diabetes, hypertension, ischemic heart disease, and chronic kidney disease, with most of them having significant association with non-hepatitis B, C-CLD. Both types of CLD had equal gender proportion (p=0.708). Among the study groups, 56.28% (n=94) had hepatitis B, C-CLD, out of which 18 (19%) belonged to Child-Pugh class A, 36 (38%) to Child-Pugh class B, and 40 (43%) to Child-Pugh class C, whereas 43.72% (n=71) had non-hepatitis B, C-CLD, comprising of 13% (n=10) of Child-Pugh class A patients, 42% (n=31) of Child-Pugh class B patients, and 44% (n=32) of Child-Pugh class C patients (p=0.631). Bilirubin levels (p=0.055), serum creatinine (p=0.201), and International normalized ratio (INR) are found higher in non-hepatitis B, C-CLD (p=0.312), whereas thrombocytopenia was more likely to be associated with hepatitis B, C-CLD (p=0.205). Hyponatremia was slightly associated with non-hepatitis B, C-CLD (p=0.281). The mean MELD score was comparable among the two study groups in both Child-Pugh classes A and B, but in Child-Pugh class C it was significantly higher in non-hepatitis B, C-CLD patients as compared to hepatitis B, C-CLD (p=0.006). Conclusion Non-hepatitis B, C-CLD was proved to be milder in Child-Pugh class A as compared to hepatitis B, C-CLD, but its mortality risk increases with severity, as mean MELD score was found significantly higher in Child-Pugh class C. Our research was able to identify severe biochemical markers in both types of CLD.

Abstract
An unrecognized latent tuberculosis infection (LTBI) may be reactivated under immunosuppressive therapy and become life threatening. Diagnosing LTBI requires the combination of targeted patient history and physical examination with the results of an interferon-gamma release assay (IGRA) and in addition, a chest X‑ray is needed to rule out active tuberculosis. Established therapies for LTBI reduce the reactivation risk by approximately 80%. For the initial screening of an HBV infection HBsAg and anti-HBc are determined. Hereby, HBsAg carriers (high HBV reactivation risk, indications for antiviral prophylaxis) and serologically resolved HBV infections (low HBV reactivation risk, use of prophylaxis only in high-risk immunosuppression) can be reliably detected. A previously unrecognized HCV infection, with an increased risk of developing liver cirrhosis during immunosuppression, can be detected in screening by anti-HCV antibodies and be successfully treated with antivirals without interferon.

Evaluation of liver tissue by ultrasound elastography and clinical parameters in children with multiple blood cell transfusions. Pediatr Radiol 2019; 49:897-905. [PMID: 30927037 DOI: 10.1007/s00247-019-04382-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 01/23/2019] [Accepted: 03/08/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Children receiving multiple blood cell transfusions are prone to iron overload and successive tissue damage in liver parenchyma, making noninvasive screening options desirable. Ultrasound (US) elastography using acoustic radiation force impulse (ARFI) imaging enables evaluation of liver parenchyma stiffness, and MRI allows for quantification of liver iron concentration. OBJECTIVE The objective was to correlate US elastography with MRI in children who had undergone bone marrow transplantation and to evaluate the modification of liver tissue with US in combination with clinical parameters at follow-up. MATERIALS AND METHODS ARFI, T2*-weighted MRI and a clinical score (HepScore, based on parameters of liver function) were performed in 45 patients (24 male; mean age 9.7 years) before and 100 days and 365 days after transplantation. All received multiple blood transfusions (mean number 22.2 up until 1 year after transplantation). We correlated US findings and HepScore with MRI findings. RESULTS We observed signs of iron accumulation in 29/45 (64.4%) patients on MRI (T2*<10 ms) and 15/45 (33.3%) showed increased tissue stiffness (ARFI>5.5 kPa). Correlation of elastography and MRI was not significant (P=0.57; n=51 matched measurements). Comparing US elastography with HepScore in receiver operating characteristic (ROC) curve analysis indicated a cut-off for affected parenchyma if HepScore was >5 points (sensitivity 67%, specificity 68%). Simultaneous increases of both indicated tissue alteration. CONCLUSION Combining US and HepScore enabled detection of liver tissue alteration through iron overload, but we found no direct significant effect of estimated iron from MRI on ARFI imaging.

Abstract
BACKGROUND In patients with chronic hepatitis C infection, a sustained virologic response (SVR) to interferon-based therapy markedly decreases the incidence of hepatocellular carcinoma (HCC) over the long term. This is also true for patients who have hepatic cirrhosis, as well as for those with HCC-with or without cirrhosis-who have undergone resection or ablation with curative intent. Recent publications, however, have reported a higher incidence of HCC among patients in both of these subgroups who were treated with direct antiviral agents (DAA) rather than interferon-based therapy. METHODS A selective search for pertinent literature was carried out in the PubMed database with the search terms "direct-acting antiviral therapy" and "hepatocellular carcinoma." RESULTS In comparison to historical patient cohorts that received interferonbased therapy, patients with hepatic cirrhosis after SVR brought about by DAA have a higher incidence of de novo HCC in 12 months (5.2-7.4%). The recurrence rate after treatment for HCC with curative intent was also higher, with marked fluctuations. Patients treated with DAA were often older and in a more advanced stage of cirrhosis than those who had received interferonbased therapy; these factors may have contributed to the observed higher incidence of HCC. On the other hand, the reduction of inflammation-triggered immune surveillance after very rapid elimination of the hepatitis C virus may have favored tumor progression. CONCLUSION Before DAA therapy is initiated in a patient who has cirrhosis or has undergone treatment for HCC with curative intent, a de novo or recurrent HCC should be meticulously excluded. Even after SVR, these patients still need intensive follow-up and surveillance.

Abstract
Background Hepatitis C Virus (HCV) infections are blood-borne, generally chronic and are associated with increased morbidity and mortality. The aim of this study is to describe the results of therapies with direct-acting antiviral agents (DAAs) in healthcare personnel. Methods Secondary data analysis using data from the Statutory Accident Insurance of the Health and Welfare Service. The study surveyed DAA therapies administered to insured parties (healthcare personnel with an HCV infection recognised as an occupational disease) in Germany between 01/01/2014 and 30/11/2016. The end points were results of monitorings carried out twelve weeks after the end of treatment (SVR12), side effects and the results of the assessment of reduced work ability after treatment. Multivariate logistic regression models were constructed to model SVR12. Results The study population (n = 180) comprised 74% women, 90% of the participants had an HCV genotype 1 infection. Two-thirds had fibrosis or cirrhosis and were treatment experienced. The most common combined therapy was ledipasvir and sofosbuvir (49%). A DAA therapy with ribavirin was administered in 20% of cases, with (pegylated) interferon and ribavirin used in 2% of cases. The majority of therapies were completed without any side effects. The overall SVR12 rate was 94%. Significant independent predictor of decrease odds of SVR12 was liver cirrhosis. Positive effects on the healthcare personnel’s work ability were observed after successful therapy. Conclusion High SVR12 rates were achieved in the sample population, with positive effects on their work ability. Early HCV therapy seems reasonable due to the increased chance of successful treatment of the infection.

Abstract
BACKGROUND & AIMS Ribavirin (RBV) is commonly used for the treatment of hepatitis C virus (HCV) infection. However, RBV is associated with a reduced quality of life (QOL). We aim to assess the impact of RBV on QOL in a real-world setting. METHODS In a prospective study, QOL was measured by a SF-36 questionnaire in 174 patients. In all, 85 patients were treated with RBV and 89 patients without RBV. QOL was assessed at baseline, week 12 of treatment and 24 weeks after treatment. RESULTS Patients treated with RBV were more likely to have HCV genotype 2 and 3 infection and cirrhosis (all P < .05). RBV-treated patients reported lower scores for several domains of QOL already at baseline. During HCV treatment, RBV-free treatment led to an increase in all measured dimensions of quality of life, whereas RBV treatment led to a decrease in the emotional and physical functioning. After treatment, all dimensions for QOL showed improvement across the study cohort, regardless whether RBV was part of the treatment regimen. However, 28.8%-45.2% of treated patients perceive a sustained reduction in their physical or mental capacity after treatment, not related to RBV usage or SVR, but related to older age (P = .03) and cirrhosis (P = .02). CONCLUSIONS During treatment, RBV leads to a reduced QOL, whereas RBV-free treatment leads to an increased QOL. After treatment, QOL strongly increases in both, RBV and RBV-free treated patients. Some patients perceive a sustained reduction in QOL, which seems unrelated to treatment.

Abstract
Precision medicine is also possible for infectious diseases as shown for the treatment of chronic viral hepatitis, especially if different options are available. In hepatitis B virus (HBV) infection, treatment indication as well as the choice of treatment and the decisions to stop treatment are based on viral markers and alanine aminotransferase (ALT) level. Future therapies for HBV infection aiming for functional cure or even virus elimination may be even more personalized and have to take into account the immune status of a given patient. Such treatment modalities might also increase the chance for successful treatment of chronic hepatitis delta where treatment options are still very limited. Some new therapeutic concepts targeting host receptors or host enzymes are promising, but may require individualized approaches. Chronic hepatitis C is a good example for precision medicine based on viral and host factors. However, the main reason for individualized direct-acting antiviral (DAA) treatment is to save costs. As DAAs are effective in more than 95% of patients, elimination of HCV seems to be possible at the level of a given country or even on a global scale. However, owing to high reinfection rates in high-risk groups and limited availability of antiviral therapy in many high endemic countries, it must still be decided whether an HCV vaccine or pre-exposure prophylaxis is required to achieve this goal. Hepatitis E is an emerging topic as this is the most frequent acute hepatitis virus infection. It can result in a chronic infection in immunosuppressed individuals. Treatment options are still limited and individualized management is based on tailoring immunosuppressive therapy and therapy with ribavirin. Thus, personalized therapy of hepatitis E virus infection is still limited.

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

Abstract
Hepatitis C virus (HCV) is a major cause of liver diseases including liver cirrhosis and hepatocellular carcinoma. Approximately 3% of the world population is infected with HCV. Thus, HCV infection is considered a public healthy challenge. It is worth mentioning, that the HCV prevalence is dependent on the countries with infection rates around 20% in high endemic countries. The review summarizes recent data on HCV molecular biology, the physiopathology of infection (immune-mediated liver damage, liver fibrosis and lipid metabolism), virus diagnostic and treatment. In addition, currently available in vitro, ex vivo and animal models to study the virus life cycle, virus pathogenesis and therapy are described. Understanding of both host and viral factors may in the future lead to creation of new approaches in generation of an efficient therapeutic vaccine.

Abstract
Surgeons routinely work in an environment with occupational risks and hazards about which they are often uninformed. Based on the currently available scientific literature this review article describes the various hazards in the operating theater and their effects on personnel, particularly from the surgical perspective. A further aim of this article is to describe the occupational safety measures to reduce the burdens and to maintain the long-term health of personnel. Ultimately, surgeons should be equipped with the necessary knowledge for implementing hazard assessments according to the German Occupational Health and Safety Act. Surgeons are exposed to increased risks and hazards by working in awkward positions with a high risk for musculoskeletal pain and injuries. They are also commonly exposed to inhalational anesthetics, surgical smoke, radiation, noise and infectious agents. Furthermore, the mental and emotional stress associated with these activities is also high. Meaningful occupational safety measures for reduction of burdens are from a technical aspect the installation of effective air extraction systems, measures to reduce exposure to radiation and noise and the use of safer instruments to prevent needle stick injuries. Furthermore, individual occupational safety measures, such as the use of personal protective equipment (e.g. radiation protective clothing and double gloves) must be observed. The consistent implementation and also adherence to these described occupational safety measures and regulations can reduce the burden on operating theater personnel and contribute to maintaining health. Furthermore, periodic preventive healthcare controls and health checks by the company medical officer and individually initiated additional prevention measures can be a sensible augmentation to these safety measures.

Abstract
BACKGROUND In Germany, medical care of prisoners is completely separated from extramural health care. The extent and quality of medical care among prisoners in Germany are therefore largely unknown. We performed a secondary data analysis of pharmacy sales data for tuberculosis (TB), HIV, hepatitis C (HCV) and opioid substitution treatment (OST) delivered to prisons in 11 federal states (FS) in Germany between 01/2012 and 03/2013. The aims of this study were to assess (i) the treatment availability for the selected diseases and OST in German prisons, (ii) the proportion of prisoners treated per FS and overall for TB, HIV, HCV and OST during the study period. METHODS Substances unique to or typically used for the treatment of each disease were defined as marker substances with defined daily doses (DDD). For each marker substance we assessed the cumulative number of DDD, the average daily number of DDD (DDDd) and average treatment prevalence per day in percent (adTP). Accordingly, the DDDd represents one person treated per day and the adTP means the proportion of prisoners treated per day. We compared the adTP of the diseases with previously measured prevalences. RESULTS We obtained data from pharmacies supplying prisons in 11 of 16 German FS. Of the included prisons, 41% were supplied with medicines for TB, 71% for HIV and 58% for HCV and OST. Twice as many delivered marker substances for TB were indicated for the continuation phase and chemoprevention than the intensive phase. The HIV adTP ranged from 0.06% to 0.94%, HCV adTP ranged from 0.03% to 0.59% and OST adTP ranged from 0% to 7.90%. The overall adTP for the respective treatment was 0.39% for HIV, 0.12% for HCV and 2.18% for OST. CONCLUSIONS According to our findings treatment rates for TB were consistent with the expected TB prevalence, at least in Berlin. HIV treatment seems to be offered to an adequate proportion of estimated infected prisoners. In contrast, the HCV treatment prevalence was low. High variation among FS in provision of all treatments, particularly of OST, point to inconsistent treatment practices, although nationwide extramural treatment guidelines for Germany exist.

Abstract
Hepatitis C virus (HCV) infection is a major health issue globally. Owing to the progress made in host genetics and HCV molecular virology, emerging data have suggested that the natural course and treatment response in patients with HCV infection are largely determined by complex host‑viral interactions. HCV genotype is the most important viral factor predicting the response to pegylated interferon‑α plus ribavirin therapy. The subtype of HCV genotype 1 is the key viral factor that predicts the efficacy of direct‑acting antiviral therapy. HCV genome heterogeneity and baseline viral load are additionally associated with the treatment response. Multiple host genetic variants localized in genes associated with the immune response have been identified as predictors of spontaneous disease course and therapy outcome in chronic HCV. However, most findings from candidate gene association studies have not been proven universal for all investigated populations and independent studies. Previous findings in independent large genome wide association studies confirmed that interferon‑λ3 gene polymorphisms are associated with spontaneous clearance and treatment responsiveness. A polymorphism of the inosine triphosphatase gene has been identified as a protective factor against ribavirin‑induced anemia and dose reductions. Another genetic variant in the patatin‑like phospholipase domain containing 3 genes is associated with hepatic steatosis and fibrosis in patients with HCV. The present review focused on the identified viral and host factors associated with outcomes of patients with HCV, and assessed the involvement of viral and host genetics in the natural history and treatment outcomes of HCV infection. This will provide novel ideas concerning personalized prevention and individualized clinical management.

Abstract
BACKGROUND The German Institute for Quality and Efficiency in Health Care (IQWiG) uses patient-relevant outcomes to inform decision-makers. OBJECTIVE IQWiG conducted a pilot study to examine whether discrete choice experiments (DCEs) can be applied in health economic evaluations in Germany to identify, weight, and prioritize multiple patient-relevant outcomes, using the example of antiviral therapy for chronic hepatitis C (HCV). A further objective was to contribute to a more structured approach towards eliciting and comparing preferences across key stakeholders. METHODS In autumn 2010, a DCE questionnaire was sent to patients with chronic HCV to estimate preferences across seven outcomes ("attributes"), including treatment efficacy [sustained viral response (SVR) at 6 months], adverse effects (flu-like symptoms, gastrointestinal symptoms, psychiatric symptoms, and skin symptoms/alopecia), and measures of treatment burden (duration of therapy, frequency of injections). A linear model and an effects coded full model were applied to assess the relative importance of the attributes. RESULTS In total N = 326 patients were included. A clear preference for SVR was shown; frequency of injections and duration of therapy shared the second rank, while psychiatric symptoms ranked third. The duration of flu-like symptoms was the least important attribute. CONCLUSION Our findings indicate that it is possible to perform a DCE at the national level in a health technology assessment agency. The weighting of multiple outcomes allows an indication-specific and evidence-based measure to be used in health economic evaluations. In decision-making in health care, the approach generally allows for consideration of patient-relevant trade-offs regarding the benefits and harms of medical interventions.

Abstract
BACKGROUND Among patients with chronic hepatitis C, 20-30% develop hepatic cirrhosis and its complications within 30 years. The antiviral treatment of hepatitis C, previously interferon-based, has recently become inter - feron-free, with resulting improvements in sustained virological response rates, safety, and tolerability and a shorter duration of treatment. METHODS This review is based on relevant publications retrieved by a selective literature search, and particularly on studies and reviews concerning the course and treatment of hepatitis C. RESULTS The available drugs for interferon-free antiviral treatment of hepatitis C include inhibitors of the RNAdependent RNA polymerase, NS3/4A protease, and NS5A protein of the hepatitis C virus (HCV), and ribavirin. Typically, two specific inhibitors are given in combination; the usual duration of treatment is 12 weeks.The antiviral drugs differ in their genotypic antiviral effectiveness and resistance barriers. The appropriate drug(s) should be chosen in consideration of the patient's hepatic and renal function and potential drug interactions. These drugs are safe and well-tolerated and result in sustained virological response rates between 90% and 100%. CONCLUSION All patients with hepatitis C, whatever their disease stage, can derive a sustained eradication of HCV from a combination of drugs with direct antiviral activity. Viral eradication is associated with a better quality of life and with lower morbidity and mortality.

Abstract
BACKGROUND There has been tremendous progress regarding treatment options for hepatitis C virus (HCV) infection. Several interferon-free regimens are awaiting regulatory approval. These innovations promise substantial reductions in the burden of disease and side effects as well as a decrease in treatment duration. OBJECTIVES The aim of this quantitaitive study was to elicit patient preferences for attributes of innovative antiviral therapies for hepatitis C. METHODS A systematic literature search and 14 semi-structured interviews were performed, resulting in eight patient-relevant characteristics. For the discrete choice experiment, an experimental design (3×3 + 5×6) was generated using Ngene software. The survey was conducted in August 2014 through computer-assisted personal interviews. The data were effects-coded in a random parameter logit estimation. RESULTS Participants were patients with HCV (N = 561; 58.1% men) in different treatment states. The analysis revealed a predominance of the attribute "reaching sustained virological response." When considering confidence intervals, the results showed three different preference ranks. At first place was "sustained virological response" (level difference [LD] 3.98), second was "anemia" (LD 1.10), followed by "number of interferon injections" (LD 0.92), "rash" (LD 0.82), "nausea and/or diarrhea" (LD 0.79), and "duration of antiviral therapy" (LD 0.78). The last position was occupied by both "tiredness/fatigue" (LD 0.31) and "headache" (LD 0.34). CONCLUSIONS From the patients' point of view, sustained virological response is the most essential criterion for choosing an HCV therapy. It was ranked at the highest, dominating all side effects and modes of administration. Furthermore, this study proved that patients consider both the probability of occurrence and the severity of treatment-induced side effects. Results clearly point to valuation of probabilities that is separate from that of severity.

Abstract
BACKGROUND Ribavirin blood levels vary considerably between patients with standard weight-based dosing. Their impact on sustained virological response (SVR) with pegylated interferon and ribavirin is controversial, but has mostly been studied before the IL28b gene polymorphism as a possible confounder was discovered. METHODS The impact of serum ribavirin trough levels at week 4, at the end of treatment and of mean levels across the entire antiviral treatment with pegylated interferon and ribavirin on relapse, SVR rates and anemia was retrospectively studied by univariate and multivariable logistic regression analyses in 214 patients with HCV genotype 1-4 infection, including 88 patients with available IL28b genotyping. RESULTS Mean ribavirin levels varied between 0.68-5.65 mg/l and significantly differed between patients with or without SVR. By multivariable regression including age, sex, HCV viral load, HCV genotype, liver fibrosis stage, prior treatments, immunosuppression and IL28b genotype, ribavirin levels consistently displayed significant influence on SVR and relapse without indication for a specific importance of higher concentrations early or late in the treatment course. Although hemoglobin decline was on average more pronounced in patients with higher ribavirin levels, hemoglobin remained relatively stable in a significant proportion of these, indicating that ribavirin levels alone are insufficient to predict anemia. CONCLUSION While data are scarce to draw conclusions applicable for modern DAA therapies, these results support ribavirin treatment based on serum levels instead of purely weight-based dosing in combination with pegylated interferon.

Abstract
The competence network for viral hepatitis (HepNet) was founded in 2002 with funding from the German government and has influenced the research on viral hepatitis in Germany. HepNet collaborator sites have been involved in numerous national and international investigator-initiated, as well as industry-sponsored, phase 1-3 studies. Within the HepNet Study-House, many groundbreaking investor-initiated trials have been completed and are still ongoing. For example, the acute hepatitis C trials and trials on chronic hepatitis D (delta), which led to therapy optimization. Continuation of the competence network on viral hepatitis has been achieved by the foundation of the German Liver Foundation, which has been an external cooperation partner of the German Center for Infection Research (DZIF) for two years. The well-established HepNet Study-House acts here as the clinical trial platform for all DZIF hepatitis trials.

Abstract
Background Liver disease, one of the most common causes of hospitalization worldwide, is particularly prevalent in Europe. This study aimed to determine the number of hospital discharges and admissions, mortality, premature death and costs associated with liver disease from the perspective of the National Health Service in Portugal. Methods A descriptive, retrospective analysis of data from 97 hospitals between 2000 and 2008, and mortality data for 2011 collected from the Portuguese National Institute of Statistics. The 9th and 10th revisions of the international classification of diseases were used to establish diagnoses. National data on demographics, average length of stay, in-patient mortality and direct costs associated with hospital admissions and liver transplantation were compared for the most common liver diseases. Mortality and premature death were compared using the potential years of life lost (PYLL) index. Results The annual mean number of discharges for liver disease was 11,503 between 2000 and 2008. Most cases of liver disease were diagnosed in men (70.4 %) and the prevalence of liver disease peaked in patients aged from 20 to 64 years (60.7 %). Alcoholic cirrhosis was the most frequent liver-disease diagnosis leading to discharge (38.6 %). In addition, alcoholic cirrhosis emerged as the main cost-driver, accounting for €26,818,930 (42.6 %) of the total cost imposed by liver disease. Overall, chronic hepatic disease was the 10th most common cause of mortality in Portugal in 2011, causing 21.8 deaths per 100,000. Chronic hepatic disease and hepatocellular carcinoma are even more important causes of premature death, ranking third based on PYLL. Conclusion In 2011, liver disease was the 10th most common cause of death and the third most important cause of premature death in Portugal. Alcohol cirrhosis was the leading cause of liver-related hospital admissions between 2001 and 2008. It appears that liver disease imposes a considerable social and economic burden on Portugal. Our results suggest that educational, legislative and therapeutic interventions to prevent morbidity, mortality and premature death from liver disease are urgently required to minimise the economic and clinical burdens.

Abstract
OBJECTIVES The aim of the study was to estimate the prevalence and associated correlates of major depressive disorder and generalized anxiety disorder in hepatitis C virus patients before and after treatment and to investigate the relationship between major depressive disorder and generalized anxiety disorder and treatment response. METHODS A total of 116 consecutive hepatitis C virus patients from hepatitis C virus treatment center in Zagazig city, Egypt, were included in the study and divided into treated group (N = 58) and untreated group (N = 58). All hepatitis C virus patients were screened for major depressive disorder and generalized anxiety disorder using hospital anxiety and depression scale, and those who screened positive were interviewed to confirm the diagnosis of major depressive disorder and generalized anxiety disorder using DSM-IV-TR diagnostic criteria. These measures were done at baseline and after 12 weeks of treatment or observation. RESULTS At baseline, 3.5% and 12.1% of hepatitis C virus patients (treated group) had major depressive disorder and generalized anxiety disorder, respectively. After 12 weeks of treatment 37.9% of hepatitis C virus patients (treated group) had major depressive disorder and 46.6% had generalized anxiety disorder. There was a significant statistical difference between hospital anxiety and depression scale scores for depression (3.3 ± 2.3 vs. 6.4 ± 3.2, t = 9.6, p = 0.001) and for anxiety (4.6 ± 2.4 vs. 7.3 ± 3.0, t = 10.2, p = 0.001) before and after treatment. There was also significant statistical difference between treated group and untreated group regarding hospital anxiety and depression scale scores after treatment and observation (depression, treated group 6.4 ± 3.2 vs. untreated group 4.0 ± 2.4, t = 3.7, p = 0.001; anxiety, treated group 7.3 ± 3.0 vs. untreated group 4.5 ± 2.3, t = 4.4, p = 0.001). There was no association between major depressive disorder and generalized anxiety disorder and treatment response. CONCLUSIONS Major depressive disorder and generalized anxiety disorder are common in hepatitis C virus patients after treatment with interferon and ribavirin and were not related to treatment response.

Abstract
BACKGROUND SNPs near the interferon lambda (IFNL) 3 gene are predictors for sustained virological response (SVR) in patients with chronic hepatitis C genotype (GT) 1. In addition, a dinucleotide frame shift in ss469415590 was described, which generates IFNL4. In this study, we compared the role of IFNL4 variants with IFNL3-(rs12979860) and IFNL3-(rs8099917) on response to pegylated (PEG)-IFN and Ribavirin (RBV) in patients with chronic hepatitis C GT2/3. METHODS We recruited 1006 patients with chronic hepatitis C and GT2/3 in a large German registry. A treatment with PEG-IFN and Ribavirin was started by 959 patients. We performed genotyping of IFNL3 (rs12979860, n = 726; rs8099917, n = 687) and of IFNL4 (ss469415590; n = 631). RESULTS Both preferable IFNL3 genotypes were associated with RVR (both p<0.0001) rather than with SVR (rs12979860: p = 0.251; rs8099917: p = 0.447). Only RVR was linked to SVR in univariate and multivariate analyzes (both p<0.001). Concordance of genotyping in patients with available serum samples and EDTA blood samples (n = 259) was more than 96% for both IFNL3 SNPs. IFNL3-(rs12979860) correlated with IFNL4: 99.2% of patients with IFNL3-(rs12979860)-CC were IFNL4-(ss469415590)-TT/TT. IFNL3-(rs12979860)-CT was linked with IFNL4-(ss469415590)-TT/ΔG (98.0%) and IFNL3-(rs12979860)-TT was associated with IFNL4-(ss469415590)-ΔG/ΔG (97.6%). CONCLUSION IFNL3 genotyping from serum was highly efficient and can be used as an alternative if EDTA whole blood is not available. In Caucasian GT2/3 patients genotyping for INFL4-(ss469415590) does not lead to additional information for the decision-making process. Importantly, IFNL3 SNPs were not associated with SVR but with RVR. Even in the era of new direct acting antiviral (DAA) therapies, IFNL3 testing may therefore still be considered for naïve GT2/3 patients to decide if dual Peg-IFN/RBV therapy is an option in resource limited regions.

[PMID: 26653754 PMCID: PMC4676160 DOI: 10.1186/s12879-015-1307-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2015] [Accepted: 12/02/2015] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Hepatitis C virus infection is highly prevalent among people who inject drugs. Opioid substitution therapy, the standard treatment for opioid dependence, provides an excellent opportunity for the treatment of hepatitis C virus infection due to the close and regular contact between patients and clinicians. However, there is little research on the impact of opioid substitution therapy on the prevalence of the hepatitis C virus at a national level. This paper describes the protocol for the Epidemiology of Hepatitis C Virus Infection among People Receiving Opioid Substitution Therapy (ECHO) study. The aim of this study is to estimate the national prevalence and incidence of hepatitis C virus infection among people receiving opioid substitution therapy in Germany and to describe factors associated with hepatitis C treatment uptake and seroconversion. METHODS/DESIGN An observational, longitudinal, multicentre study is being conducted between 2014 and 2016 in a representative sample of approximately 2500 people receiving opioid substitution therapy from about 100 clinicians providing opioid substitution therapy in Germany. Data will be collected during routine patient care and by means of patient and clinician questionnaires at baseline and 12-month follow-up. Stratified sampling will be performed to obtain a representative sample of clinicians providing opioid substitution therapy. The strata will be constructed based on the distribution of the total sample of clinicians providing opioid substitution therapy in Germany according to German Federal State and the number of patients per clinician. DISCUSSION Opioid substitution therapy may be an important strategy to prevent the spread of hepatitis C virus in opioid dependent populations, but its effectiveness may be diminished by our limited understanding of factors associated with treatment uptake and seroconversion. The present study will provide important information for developing strategies to address hepatitis C virus-related disease burden in people receiving opioid substitution therapy.

Abstract
HCV RNA assays are of central importance for virological diagnostics and for clinical planning and monitoring of an antiviral combination treatment of chronic HCV infections. The objective of the pre-market evaluation of the VERSANT HCV RNA 1.0 Assay (kPCR) was to collect analytical performance data for this new method of HCV RNA quantification and to compare them with the high standards that exist in this context. The assay exhibited a specificity of 100%. The mean intra- and inter-assay imprecision was 14.1% and 14.6%, respectively. The detection limit was determined to be 16IU/ml (95% confidence interval: 11.9-30.6IU/ml) and consequently corresponded to the manufacturer's claims (i.e. 15IU/ml). The test exhibited linearity for all HCV genotypes in a broad range from 15 to 10(8)IU HCV RNA/ml. Hence, the kPCR assay in general is well suitable for HCV RNA determinations in clinical practice. However, in a methodological comparison, a considerable under-quantification of the concentrations of HCV genotype 2 and 3 isolates was detected. Provided that the assay's manufacturer will quickly remedy this shortcoming, the VERSANT HCV RNA 1.0 (kPCR) can be called a completely reliable technique for HCV RNA quantification in routine virological diagnostics.

Abstract
BACKGROUND As part of the EU funded project "HEPscreen", the aim of this study is to identify hepatitis B and C screening and patient management guidelines, to assess the awareness of these among health professionals (HPs) and to explore the availability of hepatitis B/C training programmes for HPs in Germany, Italy, the Netherlands, the UK, Spain and Hungary. METHODS A comprehensive literature search through the main scientific databases was performed to retrieve guidelines, following which an online survey was developed and sent to HPs in six areas of health care, including public health, to verify whether HPs are aware of these guidelines, to retrieve additional guidelines and to find out whether specific professional training is available. RESULTS Twelve national guidelines were identified through the literature search. Of the 268 respondents, 80 % were aware of hepatitis B guidelines and 73 % were aware of hepatitis C guidelines in their country. The national guidelines identified through the literature search were mentioned by 1/3 of HPs in the UK and Germany, 13 % of HPs in the Netherlands, 14 % in Italy and 4 % in Spain. An additional 41 hepatitis B/C related guidance documents were retrieved through the online survey: 15 in the UK, seven in Hungary, six in Italy, five in the Netherlands, four in Germany and four in Spain. Availability of training programmes to improve skills and knowledge in viral hepatitis was most often reported in the Netherlands, with 82 % indicating availability and just 10 % indicating no availability, and least commonly in Italy, with 42 % indicating yes but 40 % indicating no. Availability was also reported by the majority in the UK, Hungary and Spain, while in Germany the majority selected unsure. CONCLUSIONS Results suggest that the scientific databases are not the most important information source of best clinical practice for many HPs. Implementation of best practices requires that guidelines are specifically designed and actively promoted among those who are to follow them. Training can disseminate these best practice recommendations and raise awareness of guidelines. It is therefore encouraging that diverse training about hepatitis B/C is available to the different professional groups.

Abstract
BACKGROUND Treatment of hepatitis C is changing dramatically. Various new direct-acting antivirals (DAA) against HCV have recently been approved or will become available during the next months. OBJECTIVES To summarize the efficacy of DAAs and to describe optimal treatment regimens for chronic hepatitis C. METHODS Review of selected phase 2 and 3 trials investigating anti-HCV drugs and recent HCV guidelines. RESULTS New HCV therapies are interferon-free and lead to sustained HCV clearance in >90% of cases. DAAs include HCV protease inhibitors, NS5A inhibitors as well as nucleotide and non-nucleoside HCV polymerase inhibitors. Depending on the stage of liver disease, HCV genotype and viral load, treatment duration is 8-24 weeks. Ribavirin is not needed anymore in every case. Resistance against HCV drugs is not a major factor determining treatment response, but resistance testing is recommended in case of treatment failures before re-treatment is considered. CONCLUSIONS Chronic hepatitis C is a curable disease. It remains to be determined to what extent HCV clearance will alter liver function and the risk for hepatocellular carcinoma in patients with liver cirrhosis.

Abstract
BACKGROUND Within the development and approval of several new direct-acting antivirals (DAA) against hepatitis C virus (HCV), a new era of hepatitis C therapy has begun. Even more treatment options are likely to become available during the next 1-2 years. METHODS A summary of the current phase II and III trials investigating DAA and a review of the recent HCV guidelines was conducted. RESULTS With the development of new potent DAA and the approval of different DAA combinations, cure rates of HCV infection of >90% are achievable for almost all HCV genotypes and stages of liver disease. Currently available DAA target different steps in the HCV replication cycle, in particular the NS3/4A protease, the NS5B polymerase, and the NS5A replication complex. Treatment duration varies between 8 and 24 weeks depending on the stage of fibrosis, prior treatment, HCV viral load, and HCV genotype. Ribavirin is required only for some treatment regimens and may be particularly beneficial in patients with cirrhosis. DAA resistance influences treatment outcome only marginally; thus, drug resistance testing is not routinely recommended before treatment. In the case of treatment failure, however, resistance testing should be performed before re-treatment with other DAA is initiated. CONCLUSION With the new, almost side effect-free DAA treatment options chronic HCV infection became a curable disease. The clinical benefit of DAA combination therapies in patients with advanced cirrhosis and the effects on incidence rates of hepatocellular carcinoma remain to be determined.

Abstract
BACKGROUND AND AIMS Individualization of treatment with peginterferon alfa and ribavirin in patients with chronic hepatitis C showed benefit in controlled trials and was implemented in treatment guidelines to increase response rates and to reduce side effects and costs. However, it is unknown whether individualization was adopted in routine daily practice and whether it translated into improved outcomes. METHODS From a large noninterventional cohort study, clinical and virologic response data of 10,262 HCV patients who received peginterferon alfa-2a and ribavirin between 2003-2007 and 2008-2011 were analyzed. To account for treatment individualization, a matched-pair analysis (2,997 matched pairs) was performed. Variation in treatment duration and dosing of ribavirin were analyzed as indicators for individualization. RESULTS Sustained virological response (SVR) rates were similar between 2003-2007 and 2008-2011 (62.0% vs. 63.7%). Patients with comorbidities were more abundant in the later period, (44.3% vs. 57.1%). The subsequent matched-pair analysis demonstrated higher SVR rates in the 2008-2011 period (64.3%) than in the 2003-2007 period (61.2%, p=0.008). More patients received abbreviated or extended treatment regimens in the later than the earlier period as an indicator of treatment individualization. To the same end, ribavirin doses were higher in the later period (12.6 versus 11.6 mg/kg/day). Factors independently associated with SVR included HCV genotype, low baseline viral load, younger age, route of infection, absence of concomitant diseases, lower APRI score, normal gamma-GT, higher ribavirin doses, no substitution for drug abuse, treatment duration, and treatment in the 2008-2011 period. CONCLUSIONS Treatment individualization with peginterferon alfa and ribavirin was implemented in daily routine between 2003-2007 and 2008-2011, SVR rates improved in the same period. These findings may be most relevant in resource-limited settings.

Abstract
BACKGROUND Sustained virological response (SVR) and virological relapse maintain pivotal roles in the management of chronic hepatitis C (CHC); however, there is little data regarding the long-term outcomes of patients with CHC in China. OBJECTIVES We aimed to investigate the predictive factors of therapeutic effect and viral relapse in patients who achieved end-of-treatment response (ETR). PATIENTS AND METHODS We retrospectively analyzed clinical, biochemical and virological data of 169 adult patients with CHC from China who were not treated with pegylated interferon-alpha (PEG IFN-α) and ribavirin, of which 142 achieved ETR and with a follow-up period ranging from six months to six years. Statistical analysis was performed by SPSS 20.0. RESULTS Of the 169 patients, 124 (73.4%) achieved SVR and 23 (16.2%) experienced relapses post-therapy in cases of ETR patients. We considered sex, age, alanine aminotransferase, aspartate transaminase, baseline hepatitis C virus RNA level, HCV genotypes, IL28B rs12979860 genotype, rapid virological response (RVR), and early virological response (EVR). For antiviral effect in patients with CHC, HCV genotypes (2, 3) (χ(2) = 11.285, P = 0.001), IL28B genotype (rs12979860 CC) (χ(2) = 16.552, P < 0.001), RVR (χ(2) = 37.339, P < 0.001), and EVR (χ(2) = 70.265, P < 0.001) were significantly correlated with achieving SVR. For ETR patients with long-term follow-up, the relapse rate within six months was significantly higher than within other periods during six-year follow-up (χ(2) = 7.792, P = 0.005). Relapse was virtually not observed after therapy ceased for 48 weeks. The IL28B genotype (rs12979860 CT/TT) (OR = 0.102; 95% CI, 0.031-0.339; P < 0.001), lower RVR (OR = 0.239; 95% CI, 0.078-0.738; P = 0.013), and EVR (OR = 0.102; 95% CI, 0.016-0.661; P = 0.017) were independent risk factors for relapse. CONCLUSIONS Our study comprehensively explored the predictive factors of therapeutic effect of administered drugs and analyzed viral relapse during a six-months to six-year follow-up period from China. The SVR may not be the perfect endpoint of HCV therapy in Chinese people; we recommend 48 weeks after treatment withdrawal as the suitable time point.

Prevalence of elevated ALT values, HBsAg, and anti-HCV in the primary care setting and evaluation of guideline defined hepatitis risk scenarios. J Hepatol 2015; 62:1256-64. [PMID: 25617500 DOI: 10.1016/j.jhep.2015.01.011] [Citation(s) in RCA: 58] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2014] [Revised: 12/22/2014] [Accepted: 01/11/2015] [Indexed: 12/26/2022]
Abstract
BACKGROUND & AIMS Prevalence data for hepatitis B and C and an evaluation of a guideline based screening in the primary care setting are not yet available. We therefore implemented a hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (HCV) screening and developed guideline based screening strategies. METHODS HBsAg, anti-HCV, and alanine aminotransferase (ALT) were included in a routine check-up together with a questionnaire covering 16 guideline adapted risk scenarios. Significant risk factors were identified by stepwise logistic regression. RESULTS 51 private practices screened 21,008 patients. The HBsAg, anti-HCV, and HCV-RNA prevalence was 0.52%, 0.95%, and 0.43%, respectively. Infections were previously unknown in 85% and 65% of HBsAg and anti-HCV positive individuals, respectively. Sexual risk factors were under-reported, while the following scenarios were significantly associated with viral infections (Odds ratio [95% confidence interval]). HBV: Immigration (4.4 [2.9, 6.7]), infection in household (2.5 [1.2, 4.5]), male gender (1.6 [1.1, 2.4]). Male immigrants had a 2.1% HBsAg prevalence and 80% were unaware of the infection. HCV: IV drug use (384 [233, 644]), blood transfusion before 1992 (5.3 [3.5, 7.9]), immigration (2.4 [1.5, 3.6]). Presence of either one of the HBV related guideline defined risk scenarios or elevated ALT identified 82% of previously undiagnosed patients. Presence of one of the three significant HCV risk factors or elevated ALT levels diagnosed 83% of unknown HCV-RNA positive cases by screening only 26% of the population. CONCLUSIONS Undiagnosed hepatitis B and C infections frequently exist in the primary care setting. Easy to apply guideline defined risk scenarios help to diagnose previously unknown infections.

Abstract
OBJECTIVE To describe potential drug-drug interactions in the area of HIV/hepatitis C virus (HCV) coinfection and injection drug use, including those between antiretrovirals (ARVs), direct-acting antivirals (DAAs), and opioid-agonist therapy, and to supply a practical approach to their management. DATA SOURCES We searched PubMed for relevant articles published up until February 2015 as well as conference reports and drug-drug-interaction Web sites. DATA SELECTION AND DATA EXTRACTION We used the following search terms: pharmacokinetic and pharmacodynamic drug-drug interaction, opioid substitution, HIV, hepatitis and the individual names of the relevant agents of the following drug classes and the drug classes itself: reverse transcriptase inhibitors, nonnucleoside reverse transcriptase inhibitors, protease inhibitors, direct-acting antivirals, opioide, benzodiazepines, anticonvulsants, antidepressants and antipsychotics. Additional references were identified from a review of literature citations and drug-drug interaction Web sites. In our evaluation, we included German- and English-language studies and reports addressing drug-drug interactions between opioid agonist therapy and ARVs or DAAs. DATA SYNTHESIS Pharmacokinetic data were available for all ARVs and DAAs except rilpivirine, indinavir, saquinavir, maraviroc, dolutegravir, and MK-8742 with buprenorphine as well as maraviroc with methadone Drug-drug interactions of potential clinical relevance are most likely to occur between opioid-replacement therapy and ARVs, particularly the nonnucleoside reverse transcriptase inhibitors, efavirenz and nevirapine, and HIV protease inhibitors. CONCLUSION Integrase inhibitors may be safely coadministered with opioid-replacement therapy. With respect to HCV DAAs, most currently approved and late-stage investigational agents do not have clinically significant interactions with opioid-replacement therapy. ARV and DAAs may interact with other drug classes commonly used in the opioid-dependent population, including benzodiazepines, antidepressants, anticonvulsants, and antipsychotics.

Abstract
BACKGROUND/AIMS Aim of this retrospective study was to analyze the efficacy, safety, and predictors of treatment success for first-generation-PI triple therapies, including either boceprevir or telaprevir, in a mono-centric "real-life" setting with respect to SVR 24. PATIENTS 131 patients (102 patients telaprevir, 29 patients boceprevir) were treated. Of these, 33/131 patients were treatment naïve, 72/131 patients had been pretreated with PEG-IFN/RBV (PR) (thereof: 36 with non-response, 30 with relapse, 6 unknown), and 26/131 patients previously had received non-pegylated interferon. 96/131 patients were infected with HCV genotype 1b. 41/131 patients had liver cirrhosis. RESULTS 95/131 (73%) patients achieved SVR 24. SVR rates for subgroups were: 26/33 (79%) for treatment naïve, 25/30 (83%) for PR-relapse, 20/36 (56%) for PR-non-response, 21/26 (81%) for non-PR pretreated patients, (26/41) 63% for patients with liver cirrhosis, 23/35 (66%) genotype 1a, 72/96 (75%) genotype 1b. Predictors of SVR 24 were eRVR and a negative viral load at PI-treatment week 4 (p < 0.0001), negative predictors were quantifiable HCV viral load at PI-treatment week 4 (p < 0.0001), baseline platelet count < 100/nl (p < 0.0001), and previous PR-non-response (p = 0.006). 33/131 (25%) patients discontinued treatment prematurely, of those 14/131 (11%) patients due to virological failure. Side effects were frequent (anemia 59/131 [45%], severe infections 6/131 [5%]). CONCLUSIONS According to our SVR 24 results, efficacy of PI-based triple therapy in our "real-life" cohort is comparable to the large multi-centric clinical trials. Pronounced side effects are frequent during therapy and often need complex therapeutic interventions. Since new DAA are available, it is open to discussion, if first-generation PI-triple therapy is no longer indicated at all.

[New direct-acting antiviral agents for the treatment of chronic hepatitis C in 2014]. Internist (Berl) 2014; 55:390-400.

Abstract
BACKGROUND The development of direct-acting antiviral agents (DAA) against the hepatitis C virus (HCV) has seen enormous progress in recent years. In 2011, the first protease inhibitors boceprevir (BOC) and telaprevir (TLV) were approved, which still need to be combined with pegylated interferon α (PEG-IFN α) and ribavirin (RBV) and are used only in patients with genotype 1. With sofosbuvir (SOF) and simeprevir (SMV), two new DAA are available. More DAA are in clinical development. OBJECTIVES Which changes in the treatment of chronic hepatitis C infection can be expected with the approval of the new DAA in 2014? Relevant phase IIb and phase III studies for the approval in 2014 were considered for drugs approved by the FDA or EMA at the editorial deadline. CURRENT DATA For patients with genotype 1, the combination of SOF, SMV or faldaprevir with PEG-IFN α and RBV was successfully evaluated in phase III studies. In contrast to previous treatment with PEG-IFN α, RBV and telaprevir (TLV) or boceprevir (BOC), therapy can be shortened in most cases with a significantly improved side-effect profile. Cure rates above 80 % are possible. Data are also available for an interferon-free therapy with either SOF and RBV or SOF and SMV in GT-1 patients. SVR rates exceeding 60 % and up to 90 % are possible. However, treatment experience with these combinations is low and an unrestricted interferon-free therapy for genotype 1 should not be expected before 2015. For patients with genotypes 2 and 3, valid data for interferon-free therapies are available. The combination of SOF and RBV for 12 weeks in genotype 2 and 24 weeks for genotype 3 is effective and shows equal or superior cure rates with fewer side effects than the PEG-IFN α/RBV therapy. CONCLUSION For patients with genotype 1, the duration of therapy can be further reduced with better side effect profile. In certain situations, therapy without PEG-IFN α is possible and should be considered. For patients with genotypes 2 and 3, an interferon-free therapy will be standard of care in 2014.

Abstract
BACKGROUND Viral hepatitis is major a public health problem affecting millions of people worldwide. Estimates assume 400 000-500 000 people chronically infected with hepatitis C virus (HCV) in Germany. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. The aim of the study was to assess the costs for treating patients with chronic HCV in Germany. METHODS We conducted a retrospective multicenter observational study. The design was approved by an ethics committee, and patients were asked for their informed consent. Patients were grouped in four different health states. Healthcare utilization data were extracted from doctor files of six medical centers in Germany. RESULTS Data of 315 patients with chronic HCV were analyzed. The mean age was 49.4 years, 57.5% were male and 67.9% had a genotype 1 infection. The most common routes of transmission were injection drug use (39.0%) and infection through blood products (15.9%). The average total cost was €19 147 including ambulatory care and diagnostics (€1686), pharmaceuticals (€14 875), inpatient care (€1293), and sick leave (€1293). For patients in stable health states (mild and moderate HCV, compensated cirrhosis), costs did not differ significantly and were mainly influenced by antiviral treatment. For patients with decompensated cirrhosis, inpatient care accounted for the largest part of the costs. CONCLUSION Treatment of HCV patients involves high costs, mainly associated with the length of antiviral therapy. Viral eradication can prevent severe disease stages, which are associated with high costs. It is necessary to follow current guidelines and monitor patients closely to avoid unnecessary costs.

Abstract
HCV RNA levels correlate with the long-term outcome of hepatitis C in liver transplant recipients. Nucleic acid testing (NAT) is usually used to confirm HCV reinfection and to examine viral loads after liver transplantation. HCV core antigen (HCVcoreAg) testing could be an alternative to NAT with some potential advantages including very low intra- and interassay variabilities and lower costs. The performance of HCVcoreAg testing in organ transplant recipients is unknown. We prospectively studied 1011 sera for HCV RNA and HCVcoreAg in a routine real-world setting including 222 samples obtained from patients after liver or kidney transplantation. HCV RNA and HCVcoreAg test results showed a consistency of 98% with a very good correlation in transplanted patients (r > 0.85). The correlation between HCV RNA and HCVcoreAg was higher in sera with high viral loads and in samples from patients with low biochemical disease. Patients treated with tacrolimus showed a better correlation between both parameters than individuals receiving cyclosporine A. HCV RNA/HCVcoreAg ratios did not differ between transplanted and nontransplanted patients, and HCV RNA and HCVcoreAg kinetics were almost identical during the first days after liver transplantation. HCVcoreAg testing can be used to monitor HCV viral loads in patients after organ transplantation. However, the assay is not recommended to monitor antiviral therapies.

Abstract
Evidence based clinical guidelines are implemented to treat patients efficiently that include efficacy, tolerability but also health economic considerations. This is of particular relevance to the new direct acting antiviral agents that have revolutionized treatment of chronic hepatitis C. For hepatitis C genotypes 2/3 interferon free treatment is already available with sofosbuvir plus ribavirin. However, treatment with sofosbuvir-based regimens is 10–20 times more expensive compared to pegylated interferon alfa and ribavirin (PegIFN/RBV). It has to be discussed if PegIFN/RBV is still an option for easy to treat patients. We assessed the treatment of patients with chronic hepatitis C genotypes 2/3 with PegIFN/RBV in a real world setting according to the latest German guidelines. Overall, 1006 patients were recruited into a prospective patient registry with 959 having started treatment. The intention-to-treat analysis showed poor SVR (GT2 61%, GT3 47%) while patients with adherence had excellent SVR in the per protocol analysis (GT2 96%, GT3 90%). According to guidelines, 283 patients were candidates for shorter treatment duration, namely a treatment of 16 weeks (baseline HCV-RNA <800.000 IU/mL, no cirrhosis and RVR). However, 65% of these easy to treat patients have been treated longer than recommended that resulted in higher costs but not higher SVR rates. In conclusion, treatment with PegIFN/RBV in a real world setting can be highly effective yet similar effective than PegIFN± sofosbuvir/RBV in well-selected naïve G2/3 patients. Full adherence to guidelines could be further improved, because it would be important in the new era with DAA, especially to safe resources.

Abstract
Anti-HCV testing is the first step to diagnose hepatitis C. Although anti-HCV assay performance improved during the last 2 decades, very high sensitivity required for screening may lead to limitations in specificity. Thus, there remains an uncertainty how to interpret anti-HCV test results with a borderline signal-to-cut-off ratio. Comparison was made of concordance and performance of four licensed anti-HCV assays in samples with borderline signal-to-cut-off ratios. Out of 12,090 consecutive samples tested for anti-HCV with the Abbott Architect Anti-HCV assay over a period of 29 months, 95 plasma samples with a signal-to-cut-off ratio between 0.5 and 2 were selected for this study. All samples were re-tested with the Enzygnost Anti-HCV version 4.0, the Ortho anti-HCV version 3.0, and the Monolisa anti-HCV-Plus version 2 assays. Discordant samples were classified by additional immunoblot testing. Overall, only 52% of the Architect borderline samples gave similar results in all four assays. Inter-assay concordance ranged between 58% and 80%. The highest discordance was observed between the Architect and the Monolisa assay (42%). In contrast, a high level of concordance was found between the Enzygnost and Ortho assays (80%). The Monolisa was best to identify negative samples (100%), while the Enzygnost correctly classified most of the positive samples (96%). Anti-HCV antibody assays show significant variation in classifying samples with low signal-to-cut-off ratios. Different performances may have cost and management implications, as false-positive results are not infrequent. However, sensitivities were good for all assays if indeterminate results are not considered as negative.

Abstract
BACKGROUND Immigrant populations are believed to be more frequently infected with hepatitis viruses. However, limited unbiased data are available on immigrants outside of academic centres. Therefore, the aim of this study was to perform large-scale screening for hepatitis markers in primary care centres treating mainly individuals with a migrational background in Germany. METHODS Between November 2010 and January 2012, we prospectively screened 1313 individuals treated by general practitioners at eight primary care centres in North-western Germany. Patients were eligible if they or their parents were not born in Germany. Serological screening for hepatitis B core protein antibodies, hepatitis B surface antigens (HBsAgs), and anti-hepatitis C virus antibodies was performed in each individual. HBsAg-positive and anti-hepatitis C virus-positive patients were further tested for molecular markers of viral replication. RESULTS The mean age was 49.1±15.8 years. Of the patients, 45.7% were male; 87.3% had migrated to Germany from the Eastern Mediterranean area and 12.0% from Eastern Europe. Of the patients, 32.5% tested positive for hepatitis B core protein antibodies. HBsAgs were found in 3.6% of patients. Overall, hepatitis B virus DNA was detected in 2.2% of patients. Markers for hepatitis C virus infection were found in an almost similar high frequency (1.9%). Individuals with migrational background showed significant deficits in knowledge on general routes of transmission. CONCLUSION Hepatitis virus infections are indeed significantly more prevalent in immigrant populations as compared with the general German population. These data underline the importance of introducing screening programs in this particular risk group.

Predictive factors for sustained virological response after treatment with pegylated interferon α-2a and ribavirin in patients infected with HCV genotypes 2 and 3. PLoS One 2014; 9:e107592. [PMID: 25238535 PMCID: PMC4169557 DOI: 10.1371/journal.pone.0107592] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2014] [Accepted: 08/12/2014] [Indexed: 12/15/2022] Open
Abstract
Background Previous trials have often defined genotype 2 and 3 patients as an “easy to treat” group and guidelines recommend similar management. Aims The present study looks for differences between the two genotypes and analyzes predictive factors for SVR. Methods Prospective, community-based cohort study involving 421 physicians throughout Germany. The analysis includes 2,347 patients with untreated chronic HCV genotype 2 (n = 391) and 3 (n = 1,956) infection treated with PEG-IFN α-2a plus ribavirin between August 2007 and July 2012. Results When compared with genotype 2 patients, those with genotype 3 were younger, had a shorter duration of infection, lower values of total cholesterol, LDL cholesterol and BMI, a higher frequency of drug use as infection mode and male gender (p<0.0001, respectively), and a higher APRI score (p<0.005). SVR was higher in genotype 2 when compared with genotype 3 (64.7% vs. 56.9%, p = 0.004). By multivariate analysis of genotype 2 patients, low baseline γ -GT and RVR predicted SVR. In genotype 3 age ≤45 years, cholesterol>130 mg/dl, a low APRI score, and a γ-GT ≥3-times ULN, RVR, and RBV starting dose were associated with SVR by multivariate analysis. Conclusions The present study corroborates that liver fibrosis is more pronounced in genotype 3 vs. 2. SVR is higher in genotype 2 versus genotype 3 partly because of follow-up problems in genotype 3 patients, in particular in those infected by drug use. Thus, subgroups of genotype 3 patients have adherence problems and need special attention also because they often have significant liver fibrosis.

Successful antiviral triple therapy in a longstanding refractory hepatitis C virus infection with an acute kidney injury. Case Rep Nephrol 2014; 2014:308729. [PMID: 25197586 PMCID: PMC4147195 DOI: 10.1155/2014/308729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2014] [Accepted: 08/04/2014] [Indexed: 11/18/2022] Open
Abstract
Introduction. The HCV infection is a common disease with many chronically infected patients worldwide. So far, the standard therapy of a chronic HCV infection consisted of interferon as single therapy or in combination with ribavirin. After approval of the two protease inhibitors, boceprevir and telaprevir, the standard therapy for patients with genotype 1 changed. In patients with acute kidney injury (AKI) these therapies are not approved and have so far not been evaluated in studies. Case Report. In April 2012, a 58-year-old female was admitted due to a cryoglobulin-positive chronic HCV infection which had been treated with interferon and ribavirin. Currently, the patient was admitted because of severe complications with an acute kidney injury. We treated our patient successfully with a boceprevir based triple therapy. Conclusion. Limited data suggests that a therapy with ribavirin in patients with AKI seems to be safe under close monitoring. Our patient was treated successfully with a protease inhibitor based triple therapy. Nevertheless, it is necessary to plan an interventional study to evaluate the exact risk-benefit profile of triple therapy regimens in patients with AKI and hepatitis C.

Abstract
This review analyzes progress and limitations of diagnosis, screening, and therapy of patients with chronic hepatitis B infection. A literature review was carried out by framing the study questions. Vaccination in early childhood has been introduced in most countries and reduces the infection rate. Treatment of chronic hepatitis B can control viral replication in most patients today. It reduces risks for progression and may reverse liver fibrosis. The treatment effect on development of hepatocellular carcinoma is less pronounced when cirrhosis is already present. Despite the success of vaccination and therapy chronic hepatitis B remains a problem since many infected patients do not know of their disease. Although all guidelines recommend screening in high risk groups such as migrants, these suggestions have not been implemented. In addition, the performance of hepatocellular cancer surveillance under real-life conditions is poor. The majority of people with chronic hepatitis B live in resource-constrained settings where effective drugs are not available. Despite the success of vaccination and therapy chronic hepatitis B infection remains a major problem since many patients do not know of their disease. The problems in diagnosis and screening may be overcome by raising awareness, promoting partnerships, and mobilizing resources.

Age-related differences in response to peginterferon alfa-2a/ribavirin in patients with chronic hepatitis C infection. World J Gastroenterol 2014; 20:10984-10993. [PMID: 25152602 PMCID: PMC4138479 DOI: 10.3748/wjg.v20.i31.10984] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2014] [Revised: 02/20/2014] [Accepted: 05/29/2014] [Indexed: 02/06/2023] Open
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.

A multicentre sero-behavioural survey for hepatitis B and C, HIV and HTLV among people who inject drugs in Germany using respondent driven sampling. BMC Public Health 2014; 14:845. [PMID: 25124485 PMCID: PMC4247126 DOI: 10.1186/1471-2458-14-845] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2014] [Accepted: 07/25/2014] [Indexed: 01/03/2023] Open
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.
