Background and Aims. There is scarcity of data in literature regarding the treatment response to sofosbuvir- (SOF-) based therapies in Chinese patients with chronic Hepatitis C Virus (HCV) infection. The aim of this study was to evaluate the efficacy and safety of SOF-based regimens for chronic hepatitis C (CHC) patients without cirrhosis in a real-world setting in mainland China.Methods. A total of 226 patients receiving SOF plus daclatasvir (DCV), ledipasvir (LDV), or velpatasvir (VEL) were enrolled from December 2014 to June 2017. The primary observation point was the percentage of patients with a sustained virologic response (SVR) at posttreatment week 12 (SVR12), and all adverse events were monitored during treatment and follow-up period.Results. The overall SVR12 rate was 96% (216/226), and individual SVR12 ranged from 93% to 100% in different treatment groups. No significant differences of efficacy were detected between genotypes 1b and 6a (98% for GT 1b versus 100% for GT 6a, P=0.322). Comparing the high success rates in GT 1b and 6a patients, SVR12 was relatively low in GT 3a and 3b patients. A significant difference in efficacy was observed between GT 3 and not GT 3 patients (77% versus 98%, respectively, P<0.001). No significant differences in efficacy were detected among different regimens (93% versus 97% versus 100%, respectively, P=0.153), gender (95% for male versus 96% for female, P=0.655), or baseline HCV RNA lever (96% versus 95%, respectively, P=0.614). Similar SVR rates were also obtained in naïve and previously treated patients (98% versus 93%, respectively, P=0.100).Conclusions. NS5B polymerase inhibitor SOF plus one of the NS5A inhibitors, such as DCV, LDV, or VEL for 12 weeks was associated with high SVR12 rates and well tolerated in HCV-infected patients without cirrhosis. Moreover, patients with DAAs failure should be retreated with more effective regimens like SOF/VEL.

Background and objectives- Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide, with majority of the patients being asymptomatic and when they present to clinicians, they have already advanced liver disease in form of cirrhosis or hepatocellular carcinoma. Data from developing countries on this evolving global health problem are sparse. Hence this study was planned with the aim to determine the HCV genotypes prevalant in patients attending a tertiary care hospital with their clinical prole. Materials and Methods- Detailed history taking and clinical examination were done of consecutive 30 patients who attended out-patient department or admitted at in- patient department of Tropical Medicine with chronic hepatitis C. Laboratory investigations like LFT, viral serology (HBsAg, AntiHCV, HIV), prothrombin time, ultrasonography of upper abdomen, HCV- RNA Quantative assay with genotyping were done. Data were collected and then analysed using standard statistical methods. Result- Of proposed 30 sample size, complete data could be collected of 28 patients and accordingly, analysis was done. Of the 28 HCV seroreactive individuals, majority (20) were males. The mode of transmission was unknown in 19 patients, blood transfusion in 5 patients who were thalassemic and hemodialysis in remaining 4 patients. Most of the patients (18/28) were asymptomatic even if their viral load was high. Most common presenting symptom was dyspepsia. LFT showed signicant transaminitis in 50% of the patients. Of the 28 seroreactive patients, 15 (53.57%) were HCV RNA positive based on RT-PCR. HCV rNA was below detectable level in 13 patients. HCV genotype 3 was the predominant genotype found in 11 individuals followed by genotype 1 found in 3 and genotype 2 was seen in one individual. Conclusion- Community screening specially among high risk individuals is needed for early diagnosis and prompt treatment of chronic hepatitis C to prevent its several complications and also to prevent community spread.

Background: Hepatitis C virus (HCV) genotypes and subtypes exhibit significant geographic variations.Aim: To analyse the distribution of genotypes/subtypes of HCV in a group of patients with chronic hepatitis C from Canton Sarajevo during 2012-2018.Material and methods:The study enrolled 247 human plasma samples of HCV-RNA positive patients with available results of HCV genotyping test.Results: During 2012-2018, the domination of subtypes 1a (34.01%), 1b (28.34%) and genotype 3 (23.89%) was registered. In 2012 and 2013, HCV subtype 1a was the most common (27/63; 42.86% and 17/40; 42.50%, respectively). In 2014, the leading HCV genotype/subtype were 3 and 1b (17/57; 29.82%). In 2015, the dominance of HCV genotype 3 (14/39; 35.90%) continued, while in 2016, the same number of HCV subtypes 1a and 1b (11/30; 36.67%) was recorded. Although in a small number of tested, during 2017, HCV subtype 1b was the most prevalent (7/14; 50.00%), and in 2018, it was replaced by a HCV subtype 1a (3/4; 75.00%). Distribution of HCV genotypes/subtypes by age group of patients varied significantly (p=0.000). The largest number of patients (71/247; 28.74%) belonged to the age category 30-39 years and HCV genotypes/subtypes 1, 3, 4, 1a and 1b were identified. Except in 2017, male gender significantly dominated (p=0.000). In males, HCV subtype 1a (68/170; 40.00%) was the most common, while in women it was HCV subtype 1b (44/77; 57.14%).Conclusion: This six-year retrospective study showed the time variations of the circulating HCV genotypes/subtypes among patients with chronic hepatitis C in Canton Sarajevo. Genotyping of the HCV has an important implications for diagnosis and treatment of the patients.

ABSTRACTIDX184 is a liver-targeted prodrug of 2′-methylguanosine (2′-MeG) monophosphate. This study investigated the safety, tolerability, antiviral activity, and pharmacokinetics of IDX184 as a single agent in treatment-naïve patients with genotype-1 chronic hepatitis C virus (HCV) infection. Forty-one patients with baseline HCV RNA ≥ 5 log10IU/ml, alanine aminotransferase (ALT) ≤ 2.5× the upper limit of normal, and compensated liver disease were dosed. Sequential cohorts of 10 patients, randomized 8:2 (active:placebo), received 25, 50, 75, and 100 mg of IDX184 once daily for 3 days, with a 14-day follow-up. There were no safety-related treatment discontinuations or serious adverse events. The adverse events and laboratory abnormalities observed for IDX184- and placebo-treated patients were similar. At the end of the 3-day treatment period, changes from baseline in HCV RNA levels (means ± standard deviations) were −0.5 ± 0.6, −0.7 ± 0.2, −0.6 ± 0.3, and −0.7 ± 0.5 log10for the 25-, 50-, 75-, and 100-mg doses, respectively, while viral load remained unchanged for the pooled placebo patients (−0.05 ± 0.3 log10). Patients with genotype-1a and patients with genotype-1b responded similarly. Serum ALT levels decreased, especially at daily doses ≥ 75 mg. During the posttreatment period, plasma viremia and serum aminotransferase levels returned to near pretreatment levels. No resistance mutations associated with IDX184 were detected. Plasma exposure of IDX184 and its nucleoside metabolite 2′-MeG was dose related and low. Changes in plasma viral load correlated with plasma exposure of 2′-MeG. In conclusion, the results from this proof-of-concept study show that small doses of the liver-targeted prodrug IDX184 were able to deliver significant antiviral activity and support further clinical evaluation of the drug candidate.
