Abstract
BACKGROUND The prevalence of HCV infection is high and it is a major cause of liver-related morbidity and mortality in hemodialysis and renal transplant patients. Diagnosis of hepatitis C virus (HCV) infection requires both HCV antibody screening and confirmatory nucleic acid testing (NAT). Hepatitis C virus core antigen (HCVcAg) is a reliable direct viral marker to identify active HCV infection. AIM To assess the clinical utility of HCV core antigen to identify active HCV infection in hemodialysis and renal transplant patients. METHODS A representative total of 231 plasma samples with a predominance of low viral load were included for HCVcAg testing and its performance characteristics were compared with the gold standard HCV RNA. RESULTS Comparison of HCVcAg with HCV RNA showed an excellent specificity of 99% (95% CI: 94.7 to 100%) and sensitivity of 80.62% (95% CI: 73.59 to 87.7%). Likewise, the PPV and NPV of HCVcAg were 99.1% (95% CI: 93.7% to 99.9%) and 80.2% (95% CI: 74% to 85.2%) respectively. The correlation between HCVcAg and HCV RNA was found to be good (R2 = 0.86, p<0.0001). Among common Indian HCV genotypes (1, 3 & 4), good correlation was observed between HCV RNA and HCVcAg (R2 = 0.81, p <0.0001). CONCLUSIONS It is the first Indian study to show that HCVcAg is a reliable, cost-effective direct marker to identify active HCV infection in hemodialysis and renal transplant patients. Implementation of HCVcAg testing could improve the accessibility to efficacious and affordable disease management in hemodialysis and renal transplant patients. In HCVcAg negative cases, sequential testing with anti-HCV antibody followed by HCV RNA could be a reliable and cost-effective approach.

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
Objectives To analyse lipid changes and tolerability in a cohort of HIV-infected patients who switched their antiretroviral regimens to rilpivirine/emtricitabine/tenofovir (RPV/FTC/TDF) in a real-world setting. Methods PRO-STR is a 48 week prospective observational post-authorization study in 25 hospitals. Patients with a viral load <1000 copies/mL, receiving at least 12 months of combination ART (cART), with constant posology for at least the prior 3 months, were categorized according to previous treatment [NNRTI or ritonavir-boosted PI (PI/r)]. Analytical tests were performed at the baseline visit, between week 16 and week 32, and at week 48. Results A total of 303 patients were included (mean age 46.6 years; male 74.0%; previous treatment 74.7% NNRTI and 25.3% PI/r). Both groups exhibited significantly reduced lipid profiles, except for HDL cholesterol, for which a non-significant increase was observed. [NNRTI patients: total cholesterol (baseline: 195.5 ± 38.4 mg/dL; week 48: 171.0 ± 35.5 mg/dL), total cholesterol/HDL ratio (baseline: 4.2 ± 1.2; week 48: 4.0 ± 1.2), HDL (baseline: 49.1 ± 12.0 mg/dL; week 48: 49.2 ± 45.8 mg/dL), LDL (baseline: 119.2 ± 30.2 mg/dL; week 48: 114.2 ± 110.7 mg/dL), and triglycerides (baseline: 136.6 ± 86.8 mg/dL; week 48: 113.4 ± 67.8 mg/dL); PI/r patients: total cholesterol (baseline: 203.2 ± 48.8 mg/dL; week 48: 173.4 ± 36.9 mg/dL), total cholesterol/HDL ratio (baseline: 4.7 ± 1.6; week 48: 4.0 ± 1.2), HDL (baseline: 46.4 ± 12.5 mg/dL; week 48: 52.1 ± 54.4 mg/dL), LDL (baseline: 127.0 ± 36.3 mg/dL; week 48: 111.4 ± 35.8 mg/dL), and triglycerides (baseline: 167.6 ± 107.7 mg/dL; week 48: 122.7 ± 72.1 mg/dL)]. The most common intolerances were neuropsychiatric in the NNRTI patients and gastrointestinal and metabolic in the PI/r patients, and these intolerances were significantly reduced in both groups at week 48 [NNRTI: neuropsychiatric (baseline: 81.3%; week 48: 0.0%); PI/r: gastrointestinal (baseline: 48.7%; week 48: 0.0%) and metabolic (baseline: 42.1%; week 48: 0.0%)]. Conclusions RPV/FTC/TDF improved the lipid profiles and reduced the intolerances after switching from NNRTI or PI-based regimens, in a cohort of HIV-infected patients.

Abstract
BACKGROUND Treatment of chronic hepatitis C genotype 3 (GT3) is more challenging compared with other genotypes. Since 2014, several new treatment regimens have been approved but sometimes based on limited data. AIM To validate the use, effectiveness and safety of anti-viral treatment in chronic hepatitis C genotype 3 infection under real-word conditions. METHODS The German Hepatitis C-Registry is a large national non-interventional real-world study for patients with chronic hepatitis C. A total of 1322 GT3 patients were enrolled (211 untreated and 1111 treated patients). RESULTS Between February 2014 and September 2015, five different treatment strategies have been used (PegIFN+RBV, PegIFN+RBV+SOF, SOF+RBV, DCV+SOF±RBV, LDV/SOF±RBV). Treatment uptake and use of treatment concepts changed markedly and rapidly during the study influenced by new approvals, guideline recommendations, and label updates. PegIFN-based therapies constantly declined while DCV-based therapies increased with one interruption after the approval of LDV/SOF, which was frequently used until new guidelines recommended not using this combination for GT3. Per-protocol SVR ranged from 80.9% in the PegIFN+RBV group to 96.1% in PegIFN+RBV+SOF treated patients. Treatment-experienced patients with cirrhosis showed a suboptimal SVR of 68% for SOF+RBV but a high SVR of 90-95% for DCV+SOF±RBV. The safety analysis showed more adverse events and a stronger decline of haemoglobin for RBV containing regimens. CONCLUSIONS Real-world data can validate the effectiveness and safety for treatment regimens that had previously been approved with limited data, in particular for specific subgroups of patients. The present study demonstrates how rapid new scientific data, new treatment guidelines, new drug approvals and label changes are implemented into routine clinical practice today.

Treatment of HCV genotype 2 with sofosbuvir and ribavirin results in lower sustained virological response rates in real life than expected from clinical trials. Liver Int 2017; 37:205-211.

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

Abstract
Background Access to direct-acting antiviral agents (DAAs) is restricted in some settings; thus, the European Association for the Study of the Liver recommends dual peginterferon/ribavirin (PegIFN/RBV) therapy wherever DAAs are unavailable. HCV genotype (GT) 3 infection is now the most difficult genotype to eradicate and PegIFN/RBV remains an effective option. The goal of this study was to devise a simple predictive score to identify GT3 patients with a high probability of achieving a sustained virologic response (SVR) with PegIFN alfa-2a/RBV therapy. Methods Relationships between baseline characteristics and SVR were explored by multiple logistic regression models and used to develop a simple scoring system to predict SVR using data from 1239 treatment-naive GT3 patients who received PegIFN alfa-2a/RBV for 24 weeks in two large observational cohort studies. Results The score was validated using a database of 473 patients. Scores were assigned for six factors as follows: age (years) (≤40: 2 points; >40 but ≤55: 1); bodyweight (kg) (<70: 2; ≥70 but <90: 1); no cirrhosis/transition to cirrhosis (2); ALT ≤2.5 x ULN (1); platelets (109/L) (>200: 2; ≥100 but <200: 1); HCV RNA (<400,000 IU/mL: 1). The points are summed to arrive at a score ranging from 0‒10 where higher scores indicate higher chances of SVR; 141, 123, 203, 249, 232, and 218 patients had total scores of 0‒4, 5, 6, 7, 8, and 9–10, respectively, among whom SVR rates were 45%, 62%, 72%, 76%, 84%, and 89%. Among 622 patients who had scores of 6‒10 and HCV RNA <50 IU/mL by treatment week 4 the SVR rate was 86% (532/622). Conclusions A simple baseline scoring system involving age, bodyweight, cirrhosis status, ALT level, platelet count and HCV RNA level can be used to identify treatment-naive Caucasian patients with HCV GT3 infection with a high probability of SVR with PegIFN alfa-2a/RBV therapy.

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
To investigate the impact of epoetin beta (EPO) on sustained virological response (SVR) in hepatitis C virus (HCV)-infected patients treated with peginterferon-ribavirin (RBV). Controlled, randomized, pragmatic multicenter study to assess 2 strategies, ie, the use (EPO group) or nonuse (control group) of EPO in terms of achieving SVR in treatment-naive, genotype non-2/non-3 HCV-infected patients receiving a 48-week treatment regimen of pegylated interferon α-2a (peg-IFN) plus RBV (randomization 2:1). The single-nucleotide polymorphisms of interferon lambda 3 (IFNL3) (rs12979860 and rs8099917), interferon lambda 4 (IFNL4) (ss469415590), and inosine triphosphatase (ITPA) (rs1127354 and rs7270101) were determined retrospectively. Two hundred twenty-seven patients were included in the study. In the global population (n = 227), the overall SVR rate was 52% (118/227). Nonresponse and relapse occurred in respectively 46/227 (20.3%) and 42/227 (18.5%) patients. In the intention-to-treat analysis, 55.5% of patients with anemia (n = 164) had a SVR, specifically 57.4% in the EPO group versus 52.4% in the control group, but the difference was not statistically significant. In the anemic population, independent factors associated with SVR were IFNL3 and IFNL4 polymorphisms, pretreatment HCV RNA level, iron level, and aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio. EPO has little impact on SVR in patients treated with peg-IFN+RBV and should be recommended only for patients with severe anemia.

Performance and Value of IFN-Lambda3 and IFN-Lambda4 Genotyping in Patients with Chronic Hepatitis C (CHC) Genotype 2/3 in a Real World Setting. PLoS One 2015; 10:e0145622. [PMID: 26699619 PMCID: PMC4689517 DOI: 10.1371/journal.pone.0145622] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Accepted: 12/06/2015] [Indexed: 12/15/2022] Open
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.

Abstract
OBJECTIVE To determine compliance and improvement in sustained viral response (SVR) by following response guided therapy (RGT) plan of interferon and ribavirin, for genotype 3 in chronic hepatitis C. METHODS Patients with chronic hepatitis C genotype 3, who were eligible for interferon-ribavirin therapy and consented for RGT, were included. Those with no rapid viral response (RVR), having coarse echotexture of liver or undergoing re-treatment, were advised 48 week treatment whereas, rest had 24 week standard therapy. PCR for HCV RNA checked 6 months after discontinuing treatment, was the primary end point of study. RESULTS Of 154 patients, included in the study with mean age of 39.9 (±10.84) and male to female ratio 1.4/1 (94/60), majority of patients, 136 (88.4%) were treatment naïve whereas, 18 (11.6%) were being retreated. On ultrasound, 63 (40.9%) patients had coarse liver and 33 (21.4%) had splenomegaly. RVR was achieved in 99 (64.3%) patients. Overall 66(42.8%) patients merited extended duration of therapy as per RGT plan but only 22 (33%) were compliant. Treatment related side effects were the dominant reason for declining RGT in 33 (75%) patients. SVR was noted in 111 (72.1%) patients. Those patients with extended therapy (RGT), had SVR 90.9% (20/22), although, better but statistically not significant than those who stopped therapy at 6 months 77.2% (34/44) (p value 0.11). CONCLUSION Response guided therapy plan did not improve SVR to pegylatedinterferon and ribavirin therapy in patients with genotype 3 and it has low patient compliance due to treatment related side effects.

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.

Treatment Extension of Pegylated Interferon Alpha and Ribavirin Does Not Improve SVR in Patients with Genotypes 2/3 without Rapid Virological Response (OPTEX Trial): A Prospective, Randomized, Two-Arm, Multicentre Phase IV Clinical Trial. PLoS One 2015; 10:e0128069.

Abstract
Although sofosbuvir has been approved for patients with genotypes 2/3 (G2/3), many parts of the world still consider pegylated Interferon alpha (P) and ribavirin (R) as standard of care for G2/3. Patients with rapid virological response (RVR) show response rates >80%. However, SVR (sustained virological response) in non-RVR patients is not satisfactory. Longer treatment duration may be required but evidence from prospective trials are lacking. A total of 1006 chronic HCV genotype 2/3 patients treated with P/R were recruited into a German HepNet multicenter screening registry. Of those, only 226 patients were still HCV RNA positive at week 4 (non-RVR). Non-RVR patients with ongoing response after 24 weeks P-2b/R qualified for OPTEX, a randomized trial investigating treatment extension of additional 24 weeks (total 48 weeks, Group A) or additional 12 weeks (total 36 weeks, group B) of 1.5 μg/kg P-2b and 800-1400 mg R. Due to the low number of patients without RVR, the number of 150 anticipated study patients was not met and only 99 non-RVR patients (n=50 Group A, n=49 Group B) could be enrolled into the OPTEX trial. Baseline factors did not differ between groups. Sixteen patients had G2 and 83 patients G3. Based on the ITT (intention-to-treat) analysis, 68% [55%; 81%] in Group A and 57% [43%; 71%] in Group B achieved SVR (p= 0.31). The primary endpoint of better SVR rates in Group A compared to a historical control group (SVR 70%) was not met. In conclusion, approximately 23% of G2/3 patients did not achieve RVR in a real world setting. However, subsequent recruitment in a treatment-extension study was difficult. Prolonged therapy beyond 24 weeks did not result in higher SVR compared to a historical control group.
