Background and Aims: The advent of direct-acting antiviral agents promises to change the management of hepatitis C in patients with end-stage renal disease, a patient group where the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a ‘real-world’ group of patients with end-stage renal disease. Methods: We performed a single-arm, multi-centre study in a cohort (n=30) of patients with advanced chronic kidney disease (mostly on dialysis) who underwent antiviral therapy with direct-acting antiviral agents. The primary end-point was sustained virologic response (serum hepatitis C virus RNA < 15 mIU/mL, 12 weeks after treatment ended). We collected data on on-treatment adverse events, serious adverse events and laboratory abnormalities. Results: In total, 23 (77%) and 7 (23%) patients underwent regular dialysis and had chronic kidney disease at pre-dialysis stage, respectively. Six regimens were adopted: elbasvir/grazoprevir ( n = 6), ledipasvir/sofosbuvir ± ribavirin ( n = 4), PrOD regimens ± ribavirin ( n = 10), simeprevir + daclatasvir ( n = 3), sofosbuvir + daclatasvir ± ribavirin ( n = 3), sofosbuvir + ribavirin ( n = 4). The SVR12 rate was 90% (95% confidence interval, 74%; 96%). A total of 27 (90%) patients achieved SVR12; there were three virologic failures – two were non-responders and one had a viral breakthrough while on therapy. Adverse events occurred in 53% (16/30) (95% confidence interval, 0.39; 0.73) of patients and were managed clinically without discontinuation of therapy or hospitalization. The most common adverse event was anaemia ( n = 12) that required blood transfusions in seven individuals; deterioration of kidney function occurred in one (14%). Conclusion: All-oral, interferon-free therapy with direct-acting antiviral agents for chronic hepatitis C virus in advanced chronic kidney disease was effective and well tolerated in a ‘real-life’ clinical setting. Careful monitoring of haemoglobin and serum creatinine during therapy with direct-acting antiviral agents is suggested. Studies are under way to address whether sustained viral response translates into better survival in this population.

Abstract Background Hepatitis C virus (HCV) is a global medical condition that causes several life-threatening chronic diseases in the liver. The conventional interferon-free treatment regimens are currently in use by a blend of direct-acting antiviral agents (DAAs) aiming at the viral NS3 protease. However, major concerns may be the issue of DAA-resistant HCV strains and the limited availability to the DAAs due to their high price. Due to this crisis, the developments of a new molecule with high potency as an NS3/4A protease inhibitor of the hepatitis-C virus remain a high priority for medical research. This study aimed to use in-silico methods to identify high potent molecule as an NS3/4A protease inhibitor and investigating the binding energy of the identified molecule in comparison with approved direct-acting antiviral agents (Telaprevir, Simeprevir, and Voxilaprevir) through molecular docking. Results The model obtained by in-silico method have the following statistical records, coefficient of determination (r2) of 0.7704, cross-validation (q2LOO = 0.6914); external test set (r2(pred) = 0.7049) and Y-randomization assessment (cR2p = 0.7025). The results from the model were used to identify 12 new potential human HCV NS3/4A protease inhibitors, and it was observed that the identified molecule is well-fixed when docked with the receptor and was found to have the lowest binding energy of − 10.7, compared to approved direct-acting antiviral agents (Telaprevir, Simeprevir, and Voxilaprevir) with − 9.5, − 10.0, − 10.5 binding energy, respectively. Conclusion The binding affinity (− 10.7) of the newly identified molecule docked with 3D structures of HCV NS3/4a protease/helicase (PDB ID: 4A92) was found to be better than that of Telaprevir, Simeprevir, and Voxilaprevir (approved direct-acting antiviral agents) which are − 9.5, − 10.0, and − 10.5, respectively. Hence, a novel molecule was identified showing high potency as HCV NS3/4a protease inhibitors.
