Abstract
The evolution of ferritin levels in hepatitis C virus (HCV)-infected patients with sustained virological responses (SVRs) following various therapy regimens remains elusive. An 8-year prospective cohort study of 1194 HCV-infected patients [interferon-based therapy (n = 620), direct-acting antiviral agent (DAA) therapy (n = 355)] was conducted. At baseline, sex, alanine aminotransferase (ALT), triglycerides, homeostatic model assessment of insulin resistance (HOMA-IR), estimated glomerular filtration rate (eGFR), hemoglobin, iron/total iron-binding capacity (Fe/TIBC) and IFNL3-rs12979860 genotypes were associated with ferritin levels. At 24 weeks posttherapy, ALT, triglycerides, total cholesterol, eGFR, Fe/TIBC and the therapy regimen were associated with ferritin levels in SVR patients. Among interferon-treated patients, ferritin levels increased at 24 weeks posttherapy, regardless of SVR, and 24-week posttherapy ferritin levels were higher in non-SVR patients (n = 111) than in SVR patients (n = 509); ferritin levels began decreasing at 3 years posttherapy and were lower than pretherapy levels since 4 years posttherapy in SVR patients. Among DAA-treated SVR patients (n = 350), ferritin levels decreased and remained stable since 24 weeks posttherapy. ALT, triglycerides, eGFR, and Fe/TIBC were HCV-unrelated factors associated with ferritin levels; sex, HOMA-IR, total cholesterol, hemoglobin and IFNL3-rs12979860 genotype were HCV-related factors associated with ferritin levels. In interferon-treated SVR patients, the increased trend of posttherapy ferritin levels was not reversed until 4 years posttherapy. In DAA-treated SVR patients, ferritin levels decreased since 24 weeks posttherapy.

Abstract
Hepatitis C virus (HCV) is endemic in Pakistan, infecting approximately 12 million people and expected to increase in the coming decades. IFIH1 is a viral RNA sensor gene essential for the activation of innate immunity against RNA viruses. Aim: The aim of the study was to analyze the association of the polymorphism (rs1990760) in IFIH1 gene among HCV infected Pakistani patients and healthy controls. Materials & methods: Blood samples from 400 chronic HCV patients (including 323 responders and 77 nonresponders) and 100 healthy individuals were collected. Results: Frequencies of heterozygous computed tomography genotype significantly associated with decreased HCV risk (χ2 = 0.072; 95% Cl: 1.06; 0.68−1.65; p ≤ 0.788). Conclusion: No significant differences were observed in alleles and genotype frequencies of IFIH1 (rs1990760) in Pakistani HCV infected patients.

Abstract
UNLABELLED Recently approved, interferon-free medication regimens for treating hepatitis C are highly effective, but extremely costly. We aimed to identify cost-effective strategies for managing treatment-naïve U.S. veterans with new hepatitis C medication regimens. We developed a Markov model with 1-year cycle length for a cohort of 60-year-old veterans with untreated genotype 1 hepatitis C seeking treatment in a typical year. We compared using sofosbuvir/ledipasvir or ombitasvir/ritonavir/paritaprevir/dasabuvir to treat: (1) any patient seeking treatment; (2) only patients with advanced fibrosis or cirrhosis; or (3) patients with advanced disease first and healthier patients 1 year later. The previous standard of care, sofosbuvir/simeprevir or sofosbuvir/pegylated interferon/ribavirin, was included for comparison. Patients could develop progressive fibrosis, cirrhosis, or hepatocellular carcinoma, undergo transplantation, or die. Complications were less likely after sustained virological response. We calculated the incremental cost per quality-adjusted life year (QALY) and varied model inputs in one-way and probabilistic sensitivity analyses. We used the Veterans Health Administration perspective with a lifetime time horizon and 3% annual discounting. Treating any patient with ombitasvir-based therapy was the preferred strategy ($35,560; 14.0 QALYs). All other strategies were dominated (greater costs/QALY gained than more effective strategies). Varying treatment efficacy, price, and/or duration changed the preferred strategy. In probabilistic sensitivity analysis, treating any patient with ombitasvir-based therapy was cost-effective in 70% of iterations at a $50,000/QALY threshold and 65% of iterations at a $100,000/QALY threshold. CONCLUSION Managing any treatment-naïve genotype 1 hepatitis C patient with ombitasvir-based therapy is the most economically efficient strategy, although price and efficacy can impact cost-effectiveness. It is economically unfavorable to restrict treatment to patients with advanced disease or use a staged treatment strategy. (Hepatology 2016;63:428-436).

Abstract
BACKGROUND Quantitative hepatitis C (HCV) polymerase chain reaction (qtHCV-PCR), the gold standard for monitoring HCV therapy, is an expensive, time-consuming procedure that requires equipped laboratories and trained personnel. AIMS To assess the accuracy and cost-effectiveness of the automated Abbott ARCHITECT HCV Ag assay (Wiesbaden, Germany) in monitoring response to pagylated interferon (PEG-IFN) and ribavirin therapy for chronic HCV genotype 4 (G4). METHODS This longitudinal, non-inferiority study compared the efficacy and cost benefit of an All-HCV core antigen assay protocol and a hybrid qtHCV RNA PCR and HCV core Ag assay protocol to the standard All-qtHCV-PCR protocol in chronic HCV G4 patients treated with pegylated interferon (PEG IFN) and ribavirin. RESULTS Four hundred and ten patients with chronic hepatitis C genotype 4 met inclusion criteria and were enrolled in the study. The sustained virological response rate (SVR) was 66.34%. The All-HCV core antigen and hybrid monitoring assays resulted in the significant cost savings without compromising performance. A good correlation existed between HCV viral load and HCV core antigen levels (r = 0.944; P < 0.0001). Baseline HCV RNA values <600 IU/mL, baseline HCV core Ag levels <2000 fmol/L, rapid virological response, rapid decline in HCV core antigen were strong predictors of SVR. CONCLUSION Hepatitis C core Ag assay is a point-of-care, reproducible, reliable, cost-effective monitoring tool with rapid turnaround time that, which can effectively replace or adjunct to qRT-PCR in monitoring interferon based or interferon-free anti-viral therapy in chronic hepatitis genotype 4 patients in resource-limited countries with a high burden of hepatitis C.

Abstract
Chronic hepatitis C virus (HCV) is the most common blood-borne pathogen in the United States. HCV disproportionately affects Veterans Affairs (VA) health-care users: 174,302 HCV-infected veterans were in VA care in 2013, making the VA the world's largest HCV care provider. This systematic review identified 546 articles related to HCV in the VA. After assessment by 2 independent reviewers, 28 articles describing prevalence and treatment of HCV in VA users ultimately met inclusion criteria. Most VA patients currently living with HCV infection were born between 1945 and 1965 and were infected with HCV between 1970 and 1990. To prevent HCV-related complications such as cirrhosis, hepatocellular carcinoma, and death, medical personnel must identify and treat HCV. However, antiviral therapy has historically been limited by medication side effects, contraindications, and patient acceptance. Although treatment initiation rates are higher in the VA than in the general United States, only 23% of VA HCV patients have received treatment and, of those, only a minority were cured. Recent development of more effective and tolerable antiviral agents represents a major pharmacological breakthrough. Eradication of HCV is theoretically possible for the majority of HCV patients for the first time, although new barriers, such as high drug costs, may limit future uptake.

Abstract
BACKGROUND Data on the efficacy of Peg-interferon/ribavirin therapy for chronic hepatitis C are mostly derived from treatment of selected patients enrolled in clinical trials. This study aimed to assess the effectiveness of Peg-interferon/ribavirin therapy in "real world" chronic hepatitis C patients in Italy. METHODS Independent observational multicentre study including consecutive patients receiving Peg-interferon/ribavirin in the 18 months before (retrospective phase) and after (prospective phase) the start of the study. RESULTS 4176 patients were eligible. The final study population consisted of 2051 patients in the retrospective and 2073 in the prospective phase. Sustained virological response was achieved by 1036 patients (50.5%) during the retrospective phase: 325 were genotypes 1/4 (34.1%) and 684 were genotypes 2/3 (67.2%) and by 800 patients (38.6%) during the prospective phase: 300 were genotypes 1/4 (28.4%) and 473 were genotypes 2/3 (51.5%). During multivariate analysis genotypes 2/3 were significantly associated with higher sustained virological response rates; cirrhosis and γ-glutamil-transpeptidase >2 times the normal limit were associated with poorer response. CONCLUSIONS The response to Peg-interferon/ribavirin therapy in "real world" clinical practice is distinctly lower than in registration trials. The difference in response rates was more pronounced among easy-to-treat than among difficult-to-treat hepatitis C virus genotypes.

Abstract
BACKGROUND To increase cure rates for Hepatitis C, barriers to treatment adherence and completion must be identified and overcome. AIMS This study systematically reviewed evidence on the psychological, lifestyle and social determinants of achieving viral eradication with antiviral therapy. METHODS An electronic search strategy was used to identify relevant studies that examined psychological, lifestyle and social factors related to achieving a sustained virological response (SVR). RESULTS Thirty-four studies that matched our criteria were identified. Of the factors that predict response to treatment, Asian ethnicity was an independent predictor of SVR. We found an indirect relationship between diet and SVR, with non-responders to treatment consuming more polyunsaturated fatty acids, fats and carbohydrates than those who attained SVR. The effect of alcohol consumption relied on the amount consumed; fewer than 30 grams daily had no effect on SVR, whereas >70 grams daily had an adverse impact on a patient's ability to achieve SVR, with termination rates up to 44% in those who drank >2 drinks a day. Patients with psychiatric illnesses had comparable SVR rates to controls if they continued psychological therapy (average 42%), although discontinuation rates were high with 11 studies reporting rates from 14 to 48%. CONCLUSIONS There are major gaps in current knowledge of the impact of variables such as diet, exercise, attitudes and coping skills on cure rates in chronic Hepatitis C. Those who drink limited amounts of alcohol or have psychiatric disorders should be offered treatment for their disease, with adjunctive education and support to improve treatment completion.
