    Journal:  Structural insights into NS5B protein of novel equine hepaciviruses and pegiviruses complexed with polymerase inhibitors. (Pubmed Central) -  Jan 24, 2020   
    Interactions of EHCV subtypes 1, 2 and TDAV polymerases with sofosbuvir showed a similar molecular interaction pattern compared to HCV-NS5B, while interactions with dasabuvir were less conserved. In silico studies of molecular interactions between these modeled structures and sofosbuvir suggest that this compound could be efficient in combating equine pathogens, thus contributing to animal welfare.

    Journal:  Discovery of pyrimidine nucleoside dual prodrugs and pyrazine nucleosides as novel anti-HCV agents. (Pubmed Central) -  Jan 17, 2020   
    To explore the application potential of dual prodrug strategies in the development of anti-HCV agents, a variety of sofosbuvir derivatives with modifications at the C4 or N3 position of the uracil moiety were designed and synthesized...Several active compounds were discovered, such as 25e (EC = 7.3 μM) and S-29b (EC = 19.5 μM). This kind of nucleosides were interesting and would open a new avenue for the development of antiviral agents.

    Journal:  A proof-of-concept study in HCV-infected Huh7.5 cells for shortening the duration of DAA-based triple treatment regimens. (Pubmed Central) -  Jan 15, 2020   
    Although a virologic breakthrough occurred after an intermittent treatment regimen at the low fixed dose, the high fixed dose cured HCV-positive Huh7.5 cells with intermittent treatment. In conclusion, HCV is persistently present below detectable levels in HCV-infected Huh7.5 cells for a long time after treatment, and a shortened therapy duration is associated with an increased risk of virologic relapse, but virologic relapse or breakthrough might be avoided by treatment with a combination of more highly effective DAAs.

    Clinical, Journal:  DAAs therapy associated with improved hepatic fibrosis in HCV-GT4 patients co-infected with HIV. (Pubmed Central) -  Jan 8, 2020   
    All these results indicate that UA is likely to be a promising lead compound against ZIKV, exhibiting a different mechanism than sofosbuvir. Treatment of HCV patients coinfected with HIV using DAAs is associated with a rapid significant regression in hepatic fibrosis, as evaluated by FibroScan, FIB-4, and APRI scores.

    Journal:  Impact of IFNL4 genotype on Interferon-stimulated Gene Expression during DAA therapy for Hepatitis C. (Pubmed Central) -  Dec 29, 2019   
    Unexpectedly, patients with the CC genotype showed a dynamic increase in ISG expression between weeks 4 and 16 of DAA therapy, while the reverse was true for non-CC patients. These data provide an important dynamic link between host genotype and phenotype in HCV therapy also potentially relevant to naturally acquired infection.

    Journal:  Electron diffraction determines molecular absolute configuration in a pharmaceutical nanocrystal. (Pubmed Central) -  Dec 20, 2019   
    Data collection on multiple positions of a crystal and an advanced-intensity extraction procedure enabled us to solve the structure ab initio. We further show that dynamical diffraction effects are strong enough to permit unambiguous determination of the absolute structure of material composed of light scatterers.

    Effect of sustained viral response on the regression of fibrosis and portal hypertension in cirrhotic HCV patients treated with Oral antiviral therapy. () -  Nov 24, 2019 - Abstract #APDW2019APDW_1408;    
    Twenty one patients with compensated HCV genotype 3-related cirrhosis with or without ascites and variceal bleed with Child pugh score B or C were given combination of sofosbuvir and daclatasvir without ribavarin for six months. Complete clinical response, variceal regression and regression of stiffness based on fibroscan following oral antivral therapy in compensated HCV cirrhosis is achievable, and may indicate regression of fibrosis and and decrease in portal pressure

    A study on Treatment of Hepatitis C with Directly acting antivirals (DAA): Central India Experience. () -  Nov 24, 2019 - Abstract #APDW2019APDW_1365;    
    Many studies in India have shown Genotype 3 as the commonest Genotype in India especially in North India. However, our study reveals predominance of Genotype 1 in central India and has shown excellent response in achieving SVR12 with DAA.

    Efficacy And Safety Of DAAs In HCV Infected, Treatment Naive patients, On Hemodialysis (P8) -  Nov 24, 2019 - Abstract #APDW2019APDW_237;    
    The patients were treated with Sofosbuvir and another DAA for 12 weeks...Patients recieved three different DAA regimens (Sofosbovir (200 mg) + Daclatasvir (60 mg) N=12, Sofosbovir (400 mg) + Daclatasvir (60 mg) N=12 and Sofosbovir (400 mg) + Velpatasvir (100 mg) N=10)... DAAs are safe and effective in the treatment of Hepatitis C infection in chronic kidney disease patients on hemodialysis.

    Are there any hurdles in the roadmap to HCV elimination by 2030?- An Observational study from a tertiary care centre in South India (P1) -  Nov 24, 2019 - Abstract #APDW2019APDW_161;    
    The low SVR 12 attainment in genotype 3,especially treatment naive cirrhotics, poses a real hurdle in the roadmap to HCV elimination. Based on our study we put forward a solution that in this group,including CHILD A, ribavirin should be added to sofosbuvir + velpatasvir/daclatasvir for 12 weeks as mutational analysis is difficult in a resource limited country like India and newer drugs recommended are unavailable here.

    Journal:  No need to discontinue hepatitis C virus therapy at the time of liver transplantation. (Pubmed Central) -  Nov 21, 2019   
    HCV associated OLP responded to DDAs irrespective of the genotype corresponding to a reduction in escudier score. Interferon-free DAA therapy of HCV-infection given in the immediate pre- and post-operative LT period is safe, well-tolerated and yields high SVR rates.

    Journal:  Improvement in Waldenström's Macroglobulinemia after Successful Treatment of HCV with Direct-acting Antivirals. (Pubmed Central) -  Nov 19, 2019   
    The recent advent of direct acting antivirals (DAAs) in the therapeutic armamentarium of HCV infection made possible treatment of patients with advanced liver disease. Here we report on a rare association of a cirrhotic patient with HCV and Waldenström's Macroglobulinemia with severe cryoglobulinemia, who had already failed an interferon-based antiviral regimen, whose haematologic disease was ameliorated by HCV eradication following treatment with sofosbuvir and simeprevir with ribavirin, and where successful treatment was accompanied also by consistent improvement in liver function and parameters of portal hypertension.

    Treatment with DAA HIV-HCV coinfected patient with XDR-tuberculosis (Sydney) -  Nov 15, 2019 - Abstract #EACS2019EACS_1502;    
    ARV switched on ABC/3TC/LPVr in 2017...Sofosbuvir (SOF) 400mg and Daclatasvir (DCV) 60 mg initiated in August of 2017 for 12 weeks...Patient mentioned obvious improvement in physical functioning, vitality and bodily pain.Our clinical case indicate good tolerability and safety profile of the treatment with Sofosbuvir contain DAAs and drug interactions with Delamanid and Bedaquiline in difficult-to-treat cohort of HIV-HCV-coinfected patients with XDR-tuberculosis. Importantly, treatment of HCV-infection improve outcome of co-morbidities and general health.

    Clinical, Journal:  Dual Sofosbuvir/Daclatasvir Therapy in Adolescent Patients With Chronic Hepatitis C Infection. (Pubmed Central) -  Nov 2, 2019   
    In this real-life study in a middle-income country, PWID treated for HCV and receiving a simple peer-support intervention demonstrated an excellent treatment response and good adherence, not associated with injecting drug use during treatment and OST at treatment initiation. Sofosbuvir/Daclatasvir combined therapy could be a safe and effective treatment in adolescent patients 12 to 17 years old with chronic HCV genotype 4 infection.

    Clinical, Journal:  Baseline resistance-guided therapy does not enhance the response to interferon-free treatment of HCV infection in real life. (Pubmed Central) -  Oct 27, 2019   
    Patients had to be DAA naïve, with the exception of sofosbuvir with/without IFN...The SVR12 rate in the RGT population was 97.2% (three relapses) whereas it was 98.8% (six relapses) in the control population (p = 0.382). Our findings suggest that testing for baseline NS5A-RASs in naïve HCV-infected patients does not enhance the rate of SVR to DAA-based IFN-free therapy in clinical practice.
