The current standard of care for the treatment of chronic hepatitis C virus (HCV) infection is combination therapy with Peg-interferon (IFN) alpha-2a or alpha-2b type plus ribavirin (RBV). This antiviral schedule can in fact avoid the three fold mortality rates associated to untreated cases with HCV infection, by inducing viral eradication and liver damage regression, so as to define the patients “definitively cured” from liver disease. This analysis describes the modalities of antiviral treatment in the Veneto region, in particular the therapy-schedule mainly used and compares the cost-effectiveness of treatment with the 2 available Peg-IFNs with strategies proposed as in the every day practice. Twelve on line hepatologic units, centralized by a network program on “Surveillance and Control of HCV Infection in the Veneto Region”, prospectively collected data and, of these, we evaluated 450 subjects that underwent antiviral therapy for chronic hepatitis or cirrhosis. A post hoc retrospective analysis of cases treated from January 2003 to December 2005 was performed, grouping the study population in 166 cases treated with Peg-IFN alpha-2a (Pegasys®, Roche, fixed-dose of 180 μg/weekly) and 284 that received Peg-IFN alpha-2b (Peg-Intron®, Schering-Plough, weight-adjusted-dose from 50 to 150 μg/weekly), both in combination therapy with ribavirin (Copegus®, Roche, or Rebetol®, Schering-Plough, weight-adjusted-dose of 15 mg/kg/daily). Epidemiological characteristics and cumulative rate of end-of-therapy response and Sustained Virological Response (SVR) were similar in the 2 groups, but 78% of cases treated with Peg-IFN alpha-2b and RBV received a significantly lower dose with respect to the weight-adjusted dose. This event conditioned efficacy to therapy as demonstrated in cases that received a < 1 μg/kg dose with respect to those treated with > 1 μg/kg (respectively SVR: 49% vs 66%, p < 0,01), particularly in genotype HCV-1 (SVR: 29% vs 51%, p = 0,01), known to be more resistant to IFN-therapy. The overall cost of antiviral therapy in this study population was about € 3,528,000/450 treated cases and considering the 269 that reached SVR (98 and 171, respectively by Peg-IFN alpha-2a or 2b and RBV therapy), the cost/SVR was € 15,632 and € 11,672 in the 2 groups. In conclusion, the optimization of Peg-IFN therapy, that is the use of the full dose, particularly in cases treated with a weight-adjusted Peg-IFN alpha-2b and RBV, at the standard of care dosage of 1.5 μg/kg/week and 15 mg/kg/day respectively, will allow a better efficacy, especially in genotype HCV-1 with an increase of 11% in SVR (43% to 54%) at a lower cost.

Pegylated interferon (PEG-IFN) alpha and ribavirin therapy has become the standard treatment in chronic hepatitis C virus (HCH)-infected patients. While thrombocytopenia associated with IFN use is frequently observed among these patients, autoimmune thrombocytopenia is one of the rarely observed adverse effects. In the present report, we present a case with chronic HCV infection in which autoimmune thrombocytopenia developed at week 7 of PEG-IFN alpha 2b plus ribavirin therapy. The patient subsequently received ursodeoxycholic acid (UDCA) treatment. Although there is not an adequate number of studies on this subject, it was concluded that the use of UDCA in cases of autoimmune thrombocytopenia that have developed due to PEG-IFN treatment in chronic HCV infection is a favorable option.

Treatment of chronic hepatitis C virus (HCV) infection has been revolutionized during last years with the development of highly potent direct-acting antivirals (DAAs) specifically targeting HCV proteins. DAAs are the current standard of care for patients with chronic hepatitis C, leading to high cure rates. However, some hurdles exist including the high cost of these therapies restricting access to patients, their inability to protect against the risk of developing hepatocellular carcinoma in patients with advanced fibrosis, and emergence of resistant variants resulting in treatment failure. New therapeutic options should be essential to overcome DAAs limitations and improve survival. By targeting host-cell factors involved in HCV life cycle, host-targeting antivirals (HTAs) offer opportunity for promising anti-HCV therapy with low mutational rate and may act in a synergistic manner with DAAs to prevent viral resistance and reduce viral replication. Moreover, HTAs could be effective in difficult-to-cure patients by acting through complementary mechanisms. In this chapter, we will focus on the latest and most relevant studies regarding the host-cell factors required in HCV infection and explored as targets of antiviral therapy, we will also discuss the HTAs evaluated in preclinical and clinical development and their potential role as alternative or complementary therapeutic strategies.

Abstract Background To eliminate hepatitis C, Rwanda is conducting national mass screenings and providing to people with chronic hepatitis C free access to Direct Acting Antivirals (DAAs). Until 2020, prescribers trained and authorized to initiate DAA treatment were based at district hospitals, and access to DAAs remains expensive and geographically difficult for rural patients. We implemented a mobile clinic to provide DAA treatment initiation at primary-level health facilities among people with chronic hepatitis C identified through mass screening campaigns in rural Kirehe and Kayonza districts. Methods The mobile clinic team was composed of one clinician authorized to manage hepatitis, one lab technician, and one driver. Eligible patients received same-day clinical consultations, counselling, laboratory tests and DAA initiation. Using clinical databases, registers, and program records, we compared the number of patients who initiated DAA treatment before and during the mobile clinic campaign. We assessed linkage to care during the mobile clinical campaign and assessed predictors of linkage to care. We also estimated the cost per patient of providing mobile services and the reduction in out-of-pocket costs associated with accessing DAA treatment through the mobile clinic rather than the standard of care. Results Prior to the mobile clinic, only 408 patients in Kirehe and Kayonza had been initiated on DAAs over a 25-month period. Between November 2019 and January 2020, out of 661 eligible patients with hepatitis C, 429 (64.9%) were linked to care through the mobile clinic. Having a telephone number and complete address recorded at screening were strongly associated with linkage to care. The cost per patient of the mobile clinic program was 29.36 USD, excluding government-provided DAAs. Providing patients with same-day laboratory tests and clinical consultation at primary-level health facilities reduced out-of-pocket expenses by 9.88 USD. Conclusion The mobile clinic was a feasible strategy for providing rapid treatment initiation among people chronically infected by hepatitis C, identified through a mass screening campaign. Compared to the standard of care, mobile clinics reached more patients in a much shorter time. This low-cost strategy also reduced out-of-pocket expenditures among patients. However, long-term, sustainable care would require decentralization to the primary health-centre level.

The review discusses the genetic polymorphisms involved in the pathogenesis of hepatitis C virus (HCV) infection, that may determine the outcome of disease. In this field earlier both certain major histocompatibility complex (MHC) alleles and some cytokine gene variants have also been studied. Recently, the genome-wide association study (GWAS) and targeted single nucleotide polymorphism (SNP) analysis have revealed that a variant in the promoter region of interleukin-28B (IL-28B) gene is strongly linked to viral clearance and it may be the strongest pretreatment predictor of treatment response in chronic hepatitis C. Last year it was shown that two genetic variants leading to inosine triphosphatase deficiency protect against haemolytic anemia in patients receiving ribavirin during antiviral treatment for chronic HCV infection.

Chronic hepatitis C virus (HCV) infections continue to be a major contributor to liver disease worldwide. HCV treatment has become highly effective, yet there are still no vaccines or prophylactic strategies available to prevent infection and allow effective management of the global HCV burden. Glycan-dependent interactions are crucial to many aspects of the highly complex HCV entry process, and also modulate immune evasion. This review provides an overview of the roles of viral and cellular glycans in HCV infection and highlights glycan-focused advances in the development of entry inhibitors and vaccines to effectively prevent HCV infection.

Background and Objectives: The COVID-19 pandemic is an ongoing public health emergency. Patients with chronic diseases are at greater risk for complications and poor outcomes. The objective of this study was to investigate the liver function abnormalities and clinical outcomes in patients with COVID-19 and chronic hepatitis C. Materials and Methods: This retrospective, single-center study was conducted on a cohort of 126 patients with a history of hepatitis C, confirmed with COVID-19 between 01 April 2020 and 30 December 2020. Several clinical outcomes were compared between patients with active and non-active HCV infection, and the risks of liver impairment and all-cause mortality in active HCV patients were analyzed using a multivariate logistic regression model. Results: Among 1057 patients under follow-up for chronic HCV infection, 126 (11.9%) were confirmed with COVID-19; of these, 95 (75.4%) were under treatment or achieved SVR, while in the other 31 (24.6%), we found active HCV replication. There was a significantly higher proportion of severe COVID-19 cases in the active HCV group as compared to the non-active HCV group (32.2 vs. 7.3%, p < 0.001). Multivariate analysis showed that age, sex, alanine aminotransferase, C-reactive protein, procalcitonin, and HCV viral load were significant independent risk factors for liver impairment and all-cause mortality. The length of stay in hospital and intensive care unit for COVID-19 was significantly higher in patients with active HCV infection (p-value < 0.001), and a higher proportion of these patients required mechanical ventilation. Conclusions: Active HCV infection is an independent risk factor for all-cause mortality in COVID-19 patients.
