INTRODUCTION:Hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. The goal of HCV therapy is to eradicate the infection, which results in eliminating detectable circulating HCV after cessation of treatment, to prevent complications.METHODS:A prospective analysis was undertaken in the primary referral center in Turin. Throughout the use of questionnaries submitted to healthcare professionals, clinical and economic data from three different care pathways of HCV treatment were collected and processed. Costs were measured up to 8, 12, and 24-weeks treatment and based on time-driven activity-based costing (ABC) of the two main HCV treatments, Sovaldi and Harvoni. For the ABC analysis, three types of care pathways were considered, based on patient's clinical history resources used: patients treated for 8, 12, and 24 weeks. Gastroenterologists, pharmacists, administrative personel, and storemen were involved in the project. The aim of the analysis was to evaluate the organizational impact of the three different strategies for the treatment of HCV infection with Harvoni or Sovaldi and to estimate the differential cost.RESULTS:The data indicates that shortening treatment from 24 to 12 weeks and from 24 to 8 weeks leads to a saving of EUR192 and EUR766 for both treatment strategies. When drug costs are also taken into account, the reduction of treatment with shortening treatment from 12 to 8 weeks leads to a saving of EUR15,252.77, a reduction of EUR60,691.07 from 24 to 8 weeks for Harvoni treatment. The reduction of treatment with shortening from 24 to 12 weeks for Sovaldi leads to a saving of EUR37,668.30. The paths of 8 and 12 weeks are those associated with fewer resources in terms of professional's time, costs relating to laboratory tests, and cost of drugs.CONCLUSIONS:The reduction of the amount of time spent by healthcare professionals in the 12 weeks and in the 8 weeks strategies allows a reallocation of the resources employed.

Chronic Hcv

Hepatitis C virus (HCV) infection often causes liver diseases, including fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Liver fibrosis is the outcome of the wound healing response to tissue damage caused by chronic HCV infection. This process is characterized by the excessive accumulation of extracellular matrix (ECM) proteins, such as collagen fibers secreted by activated hepatic stellate cells (HSCs). Activation of HSCs from the quiescent stage is mediated by different mechanisms, including pro-inflammatory cytokines and chemokines released from HCV-infected hepatocytes and liver macrophages. HCV infection modulates the expression of different microRNAs that can be transported and delivered to the HSCs via exosomes released from infected cells, also leading to the development of advanced disease pathogenesis. Although recent advancements in direct-acting antiviral (DAA) treatment can efficiently control viremia, there are very few treatment strategies available that can be effective at preventing pathogenesis in advanced liver fibrosis or cirrhosis in patients. Assessment of fibrosis is considered to be the major part of proper patient care and decision making in clinical practice. In this review, we highlighted the current knowledge of molecular mechanisms responsible for the progression of liver fibrosis in chronically HCV-infected patients, and currently available methods for evaluation of fibrosis in patients. A detailed understanding of these aspects at the molecular level may contribute to the development of new therapies targeting HCV-related liver fibrosis.

Chronic Hcv

ABSTRACTHepatitis C virus (HCV) is a global health problem, affecting approximately 3% of the world's population. The standard treatment for HCV infection is often poorly tolerated and ineffective. Therefore, the development of novel or more effective treatment strategies to treat chronic HCV infection is urgently needed. In this report, BP008, a potent small-molecule inhibitor of HCV replication, was developed from a class of compounds with thiazol core structures by means of utilizing a cell-based HCV replicon system. The compound reduced the reporter expression of the HCV1b replicon with a 50% effective concentration (EC50) and selective index value of 4.1 ± 0.7 nM and >12,195, respectively. Sequencing analyses of several individual clones derived from BP008-resistant RNAs purified from cells harboring HCV1b replicon revealed that amino acid substitutions mainly within the N-terminal region (domain I) of NS5A were associated with decreased inhibitor susceptibility. Q24L, P58S, and Y93H are the key substitutions for resistance selection; F149L and V153M play the compensatory role in the replication and drug resistance processes. Moreover, BP008 displayed synergistic effects with alpha interferon (IFN-α), NS3 protease inhibitor, and NS5B polymerase inhibitor, as well as good oral bioavailability in SD rats and favorable exposure in rat liver. In summary, our results pointed to an effective small-molecule inhibitor, BP008, that potentially targets HCV NS5A. BP008 can be considered a part of a more effective therapeutic strategy for HCV in the future.

Background: Prevalence of Hepatitis C viral infection and its major risk factors has been found out in population of Batkhela, Khyber Pakhtunkhwa, Pakistan by taking number of volunteers from the interested area. HCV prevalence has not been researched in recent time here in this area, so that’s why we contributed. Materials and Methods: Ab rapid test cassette serum/plasma (USA) kit has been used for the mentioned purpose following by ELISA and finally PCR to find out active infection of virus. ICT positive individuals were reconfirmed by ELISA and then ELISA positive samples were carefully investigated by RT-PCR for Hepatitis C Virus. Results: The study population was of 770 volunteers belonging to the mentioned area of research, 453 males and 317 females. The overall prevalence was found to be 5.32% of HCV in Batkhela. This prevalence ratio was 3.12% in males and 2.20 % in females. 3rd generation ELISA was used to refine ICT positive samples which showed that 37 of the ICT positive samples had antibodies detected by ELISA. To find out active HCV infection, ELISA positive samples were refined by real time PCR which showed 2.98% of prevalence of active HCV infection in Batkhela based on HCV RNA in their blood. Principle Conclusion: Overall prevalence was found 5.32%, contaminated reused syringes and blades at Barbour’s shop, blood transfusion, surgical operations and unhygienic food in stalls etc were found significant risk factors for acquiring HCV infection. Body weakness and pale yellow skin color was common symptom in HCV positive volunteers. Safe sexual activities, blood screening before donation and sterilizing surgical equipment’s can protect us from Hepatitis C Virus.

Chronic Hcv

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.

This article describes a patient presenting with a sensory polyneuropathy and multiple autoantibodies, leading to the diagnosis of hepatitis C virus (HCV) infection. His widely positive autoantibody profile in the absence of clinically significant rheumatic disease illustrates the importance of interpreting autoimmune serology in the appropriate clinical context and the concept of HCV being a non-specific activator of the immune system. In addition, it highlights the importance of considering untreated HCV infection in the differential diagnosis of rheumatic complaints, particularly if the workup reveals multiple autoantibodies, as HCV is a potentially severe and life-threatening disease, which can be appropriately managed with effective antiviral therapy.
