Background And Aim: IL28B gene polymorphisms have been associated with treatment-response (sustained virological response, SVR) in genotype 1 hepatitis C virus (HCV)-infected patients, but only with early phase of viral decline (rapid virological response, RVR) with genotype 3 HCV-infected patients. Association between IL28B variants and SVR in genotype 3 HCV- infected patients is unclear. Our study aimed to replicate the association of IL28Bsingle nucleotide polymorphism (SNP) rs8099917 with SVR and to validate its association with RVR in genotype 3 HCV-infected patients.
Methods: 72 patients receiving combination therapy (interferon-alpha and ribavirin) at different Indian centers were retrospectively recruited and their genotype atrs8099917 was determined. The association with RVR and SVR was tested taking in to account the variation in relevant covariates such as age, gender, baseline HCV RNA copy number and liver enzymes.
Results: The minor allele frequency (MAF) in the pooled samples was 0.17 at rs8099917 (G allele). 68% had TT, 29% had GT and 3% had the GG genotype. SVR was achieved in 71% of patients. A significant association ofrs8099917 with both RVR (p = 0.026) and SVR (p = 0.016) was observed with none of the covariates showing any significant association. The relapse rate was high (20%) but no association of rs8099917 was observed with relapse (p = 0.420).
Conclusion: An IL28B SNP associates with both early phase of viral decline and sustained response in a cohort of genotype 3 HCV-infected patients from India.

Background And Aims: Pan-genotypic ribavirin-free oral direct-acting antivirals, including the glecaprevir/pibrentasvir combination, are recommended for the treatment of most patients with chronic hepatitis C virus (HCV) infection. In Romania, the HCV-infected patient population receiving glecaprevir/pibrentasvir is not well characterized and data on treatment effectiveness is lacking. The ODYSSEY study aimed to provide insights into the characteristics and treatment outcomes of HCV-infected Romanian patients receiving 8-week therapy with glecaprevir/pibrentasvir.

Hepatitis C virus (HCV) infection is one of the major health burdens worldwide. Its course depends on the virus itself and the host's immune responses. The latter are conditioned by immunogenetic factors, in particular human leukocyte antigens (HLAs), whose role in determining the outcome of infection varies according to populations and ethnic groups.

Aim Of The Study: The aim of the study was to characterize the population with hepatitis C virus (HCV) infection and steatotic liver disease (SLD) in comparison to the non-SLD HCV-infected patients and to evaluate the effectiveness of treatment with direct-acting antivirals (DAA).
Material And Methods: The analysis included 62 patients diagnosed with SLD and 14,284 non-SLD patients from the EpiTer-2 database for the period 2015-2022.
Results: Unlike the non-SLD population, the SLD group was dominated by men (49.
HCV is marked by genetic diversity that impacts disease progression and outcome. Using the NHANES data from 266 HCV-infected adults (2011-2020), this study infers that genotype 1a is the most prevalent (60.2%).
