We reported the first real data about efficacy of interferon-free therapy of chronic hepatitis C in the Czech Republic. Patients were treated with combined therapy of paritaprevir/ritonavir + ombitasvir + dasabuvir with or without ribavirin. There were 109 patients, predominantly men - 62 (57 %), most of them infected by genotype 1b - 101 patients (93 %), minority infected by genotypes 1a (6/109, 5 %) and 4 (2/109, 2 %). Both treatment-naive (43/109, 39 %), and treatment-experienced patients (66/109, 61 %) were treated...

HCV has complex interactions with human lipid metabolism leading to down regulation of cholesterol levels. Interferon therapy has been shown to decrease cholesterol even further. With the availability of second generation direct acting antiviral agents (DAA) the effect of suppressing and eliminating HCV on lipid metabolism warrants reevaluation. 
Methods: Prospective German multicenter cohort on HCV- and HIV/HCV-infected patients treated with direct antiviral agents (GECCO). Lipids were assessed at baseline, during and after therapy...

Hepatitis C virus (HCV) infection is associated with tremendous morbidity and mortality due to liver complications. HCV infection is also associated with many extrahepatic manifestations including cardiovascular diseases, glucose metabolism impairment, cryoglobulinemia vasculitis, B cell non-Hodgkin lymphoma and chronic kidney disease (CKD). Many studies have shown a strong association between HCV and CKD, by reporting (i) an increased prevalence of HCV infection in patients on haemodialysis, (ii) an increased incidence of CKD and proteinuria in HCV-infected patients, and (iii) the development of membranoproliferative glomerulonephritis secondary to HCV-induced cryoglobulinemia vasculitis...

BACKGROUND: Direct antiviral therapies for chronic hepatitis C virus (HCV) infection have expanded treatment options for neglected patient populations, including elderly patients who are ineligible/intolerant to receive interferon (IFN)-based therapy. AIM: To investigate the efficacy, tolerability and potential for drug-drug interactions (DDIs) of IFN-free treatment in patients aged ≥65 years in a large real-world cohort. METHODS: A total of 541 patients were treated with different combinations of direct antiviral agents (DAAs: ledipasvir/sofosbuvir ±ribavirin; daclatasvir/sofosbuvir ±ribavirin; paritaprevir/ombitasvir ±dasabuvir ±ribavirin or simeprevir/sofosbuvir ±ribavirin in genotype 1/4, and daclatasvir/sofosbuvir ±ribavirin or sofosbuvir/ribavirin in genotype 2/3)...

Recent evidence has been accumulated showing a negative impact of chronic hepatitis C virus infection on survival in patients with chronic kidney disease. Moreover, it appears that anti-HCV positive status has been associated with an increased risk of developing chronic kidney disease in the adult general population. These reports have emphasized the need for safe and effective therapies for hepatitis C virus infection in the chronic kidney disease population. Treatment of HCV has made considerable progress with the approval of interferon-free, direct-acting antiviral drug-based combination therapies among patients with intact kidneys; but a paucity of information exists regarding chronic kidney disease patients...

Hepatitis C virus (HCV) infection is a major health issue around the world and HCV NS3/4a protease inhibitors have been the focus of intensive research for the past 20 years. From the first identification of substrate-derived peptide inhibitors to the complex, macrocyclic compounds, including paritaprevir and grazoprevir, that are currently available, the field has used structure-based design to confront the issues of potency, resistance and pharmacokinetics. Numerous breakthrough structures from a multitude of companies have led to compounds that are now key components of combination therapies with cure rates of >90%...

AIM: Several direct-acting antiviral agents (DAAs) have marketing authorization in Europe and in the USA and have changed the landscape of hepatitis C (HCV) treatment: each DAA has its own metabolism and drug-drug interactions (DDIs), and managing them is a challenge. To compile the pharmacokinetics and DDI data of the new DAA and to provide a guide for management of DDI. METHODS: An indexed MEDLINE search was conducted using the keywords: DAA, hepatitis C, simeprevir, daclatasvir, ledipasvir, sofosbuvir, 3D regimen (paritaprevir/ritonavir, ombitasvir, dasabuvir), DDI and pharmacokinetics...

The United States Food and Drug Administration recently warned that the direct acting antiviral (DAA) combination hepatitis C virus (HCV) treatment of Paritaprevir, Ombitasvir, Dasabuvir, Ritonavir, and Ribavirin (PODr + R) can cause severe liver injury in patients with advanced liver disease. Drug induced liver injury was observed in a small number of patients with decompensated cirrhosis treated with other DAAs, but has not been reported in patients with compensated cirrhosis. We report a case of a 74-year-old woman with chronic HCV and Child-Pugh class A cirrhosis (compensated cirrhosis) treated with PODr + R...
