Abstract
INTRODUCTION The countries of Central Asia, including Kyrgyzstan, are characterized by high prevalence and morbidity of HCV infection. Identification of HCV genotype and mutations associated with resistance to direct-acting antiviral (DAA) plays an important role either in conducting molecular epidemiological studies or choosing the treatment tactics. The aim of the work was to research of the genotype diversity of HCV variants circulating in Kyrgyzstan and the identification among them the mutations associated with the development of resistance to DAA. MATERIALS AND METHODS 38 serum samples from HCV-infected residents of Kyrgyzstan were analyzed in this study. The nucleotide sequences of viral gene fragments (NS3, NS5A, NS5B) were determined by Sangers sequencing and deposited in the international GenBank database under the numbers ON841497ON841534 (NS5B), ON841535ON841566 (NS5A), and ON841567ON841584 (NS3). RESULTS The HCV subtypes 1b (52.6%; 95% CI 37.367.5%), 3a (44.8%; 95% CI 30.260.2%) and 1a (2.6%; 95% CI 0.513.4%) are circulating in Kyrgyzstan. 37% (95% CI 1959%) of subtype 1b isolates had C316N mutation in the NS5A gene; 46% (95% CI 2370%) had F37L mutation in the NS5A gene; 45% (95% CI 2272%) had Y56F mutation in the NS3 gene. Among subtype 3a isolates, resistance-associated mutations in NS5B fragment were not found. 22% (95% CI 945%) of subtype 3a sequences had a Y93H mutation in the NS5A gene. A combination of Y56F + Q168 + I170 mutations was identified among all sequences of NS3 gene. DAA resistance mutations were not found in NS3, NS5A, NS5B genes of subtype 1a sequence. CONCLUSION A rather high prevalence of mutations associated with resistance or significant decrease in sensitivity to DAA among HCV sequences from Kyrgyzstan was shown. Updating of data on HCV genetic diversity is necessary for timely planning of measures to combat epidemic.

Abstract
Background Fibromyalgia (FM) is a complex disorder characterized by chronic widespread pain and significant patient burden. Patients with chronic hepatitis C are reportedly predisposed to the development of FM. Direct-acting antiviral drugs (DAA) achieved a remarkable therapeutic efficacy in CHC patients. We therefore investigated the impact of DAA on FM symptoms in CHC patients. Methods We enrolled consecutive CHC patients who received DAA. FM symptoms were evaluated based on the 2016 American College of Rheumatology (ACR) fibromyalgia scale at baseline and 12 and 24 weeks after cessation of DAA therapy. Logistic regression was performed to determine the influence of HCV on FM at baseline. We also recruited individuals who underwent a health checkup examination as the control group, and calculated the standardized prevalence ratio of FM in CHC patients. Comparisons of fibromyalgia in different time points were undertaken using the Wilcoxon signed-rank test. Results A total of 33 CHC patients (15 males and 18 females) and 402 controls were recruited. All CHC patients achieved sustained virological response. Two (6%) patients and two (0.5%) controls fulfilled the diagnostic criteria for FM, and the standardized prevalence ratio was 23.9 in CHC patients. Logistic regression also showed increased odds for FM in CHC patients after adjusting for age and sex (OR: 14.4; 95%CI: 1.6, 128.0). In addition, their fibromyalgianess scale decreased at 12 and 24 weeks after DAA therapy. In conclusion, CHC patients were more likely to develop FM. Implementation of DAA therapy might improve FM symptoms in these patients.

Abstract
BACKGROUND Patients with inherited blood disorders (IBLD) have a high risk of hepatitis C virus (HCV) infection. The aim of this work was to assess the efficacy and safety of HCV direct-acting antiviral (DAA)-based treatment in patients with IBLD and chronic HCV infection. METHODS Twenty-seven patients (25 with sickle cell disease, 1 with β-thalassemia and 1 with hemoglobin D-Punjab), including 3 with compensated cirrhosis, were included. They were treated with sofosbuvir in combination with ribavirin, daclatasvir, ledipasvir, or velpatasvir or with grazoprevir/elbasvir for 8 or 12 weeks. In the case of treatment failure, in-vitro assessment of resistance-associated substitutions (RASs) and full-length genome sequence analysis by means of deep sequencing were performed. RESULTS Treatment was safe and well-tolerated and there were no drug discontinuations due to DAA-related adverse events. Twenty-five out of the 27 patients (93%) achieved sustained virological response 12 weeks post-treatment. One patient discontinued after 18 days due to adverse events unrelated to the antiviral treatment. One patient infected with 'unusual' genotype 2 subtype 2m relapsed. Subtype 2m naturally carries the NS5A L31M RAS. In a genotype 2a subgenomic replicon model, L31M increased daclatasvir effective concentration 50% (EC50) by 97-fold, but velpatasvir EC50 by only 3-fold, without altering the replication capacity. This patient was successfully retreated with sofosbuvir/velpatasvir for 12 weeks. CONCLUSION DAA-based regimens are well tolerated and highly efficacious in patients with chronic hepatitis C and IBLD in the real-world setting. Thus, DAA-based antiviral treatment should be prioritized in this thus far neglected population of HCV-infected patients.

Abstract
INTRODUCTION The conventional interferon therapy of hepatitis C virus has been substituted substantially with sofosbuvir and daclatasvir due to constraints in efficacy and tolerability. This study aimed diagnostically to monitor the effectiveness and side effects of direct-acting antivirals in the management of HCV infections. METHODOLOGY This prospective study was conducted on HCV-infected patients treated with sofosbuvir and daclatasvir. Different serological, biochemical, hematological, and molecular techniques were used for the assessment of patients. Only treatment-naive patients aged ≥ 18 to 75 years received 12 weeks of treatment. The primary endpoint was a sustained virologic response with undetectable HCV RNA in the patients' serum at the end of the treatment. RESULTS We identified 229 cases of confirmed HCV infections by PCR, 94.3% of which had genotype 3. The study population comprised 66% females and 34% males with a median age of 42.2 ± 10.6 SD. Ninety-three percent of the patients accomplished SVR at week 12. The combined therapy of SOF/DAC achieved the highest efficacy rate (92.6%) among the different HCV genotype 3 patients. A statistically significant relationship was observed between low baseline viral load (p < 0.001; 95% CI = 1.2-3.1) and HCV genotype 3 with minor side effects, including lethargy, headache, nausea, insomnia, diarrhea, and fever. CONCLUSIONS HCV-infected patients can be treated well with an interferon-free SOF/DAC regimen, tolerated with generally mild adverse effects with a higher SVR.

Abstract
Human beings are in dire need of developing an efficient treatment against fierce viruses like hepatitis C virus (HCV) and Coronavirus (COVID-19). These viruses have already caused the death of over two million people all over the world. Therefore, over the last years, many direct-acting antiviral drugs (DAADs) were developed targeting nonstructural proteins of these two viruses. Among these DAADs, several drugs were found more effective and safer than the others as sofosbuvir, ledipasvir, grazoprevir, glecaprevir, voxilaprevir, velpatasvir, elbasvir, pibrentasvir and remdesivir. The last one is indicated for COVID-19, while the rest are indicated for HCV treatment. Due to the valuable impact of these DAADs, larger number of analytical methods were required to meet the needs of the clinical studies. Therefore, this review will highlight the current approaches, published in the period between 2017 to present, dealing with the determination of these drugs in two different matrices: pharmaceuticals and biological fluids with the challenges of analyzing these drugs either alone, with other drugs, in presence of interferences (pharmaceutical excipients or endogenous plasma components) or in presence of matrix impurities, degradation products and metabolites. These approaches include spectroscopic, chromatographic, capillary electrophoretic, voltametric and nuclear magnetic resonance methods that have been reported during this period. Moreover, the analytical instrumentation and methods used in determination of these DAADs will be illustrated in tabulated forms.

Abstract
Currently, direct-acting antiviral drugs (DAAs) are widely used as therapeutic methods for hepatitis C virus (HCV)-positive patients, however, patients may experience treatment failure, and the dynamic changes of HCV genomes in these patients are unknown. In this study, three real-world DAAs cohorts were enrolled to observe clinical efficacy. In addition, serum samples from treatment failure patients at baseline and relapse were used to analyze changes of the HCV genomes at near full-length genome level, including resistance-associated variants (RAVs), viral quasispecies diversity and selection analysis. Next-generation sequencing was used as the detection method. The overall sustained virological response at 12 w after the end of treatment was achieved in 91.9% (57/62) of HCV patients, and 3 paired samples obtained from relapsed patients. All the 3 patients harbored baseline NS5A RAVs, the frequency of NS5A RAVs increased in 2 patients and a new NS5A RAV emerged in 1 patient at relapse, and almost all the viral strains existed with NS5A RAVs at relapse. The results of the viral quasispecies diversity analysis revealed that viral quasispecies diversity decreased at relapse compared to baseline, and the results of selection analysis indicated that the virus population experienced a bottleneck phenomenon, recent selective sweep and population expansion or was under purification selection after DAAs treatment. This study indicated that the clinical efficacy was excellent in real-world DAAs cohorts, and the viral strains existed at relapse were selective by DAAs therapy.

Abstract
Background and Objectives: Chronic hepatitis C virus infection affects about 71 million people worldwide. It is one of the most common chronic liver conditions associated with an increased risk of developing liver cirrhosis and cancer. The aim of this study was to evaluate changes in liver fibrosis and the risk of developing hepatocellular carcinoma after direct-acting antiviral drug therapy, and to assess factors, linked with these outcomes. Materials and Methods: 70 chronic hepatitis C patients were evaluated for factors linked to increased risk of de novo liver cancer and ≥ 20% decrease of ultrasound transient elastography values 12 weeks after the end of treatment. Results: The primary outcome was an improvement of liver stiffness at the end of treatment (p = 0.004), except for patients with diabetes mellitus type 2 (p = 0.49). Logistic regression analysis revealed factors associated with ≥ 20% decrease of liver stiffness values: lower degree of steatosis in liver tissue biopsy (p = 0.053); no history of interferon-based therapy (p = 0.045); elevated liver enzymes (p = 0.023–0.036); higher baseline liver stiffness value (p = 0.045) and absence of splenomegaly (p = 0.035). Hepatocellular carcinoma developed in 4 (5.7%) patients, all with high alpha-fetoprotein values (p = 0.0043) and hypoechoic liver mass (p = 0.0001), three of these patients had diabetes mellitus type 2. Conclusions: Liver stiffness decrease was significant as early as 12 weeks after the end of treatment. Patients with diabetes and advanced liver disease are at higher risk of developing non-regressive fibrosis and hepatocellular carcinoma even after successful treatment.

Abstract
OBJECTIVE To evaluate the safety and efficacy of shortened 8-week regimen of ledipasvir/sofosbuvir (LED/SOF) combination therapy in treatment-naïve children without cirrhosis aged 4-10 years of age with chronic hepatitis C virus (HCV) infection. STUDY DESIGN This observational single arm prospective study included 30 treatment-naïve children (20 males) with proved chronic HCV fulfilling inclusion criteria. Their body weights ranged from 17 to 26 kg. Four patients were excluded from the study. All the included children received a single oral dose of LED/SOF 45/200 mg for 8 weeks. Body weight, HCV-RNA, complete blood count, and liver function tests were monitored at 0, 2, 4, and 8 weeks and sustained virologic response was evaluated after 12 weeks after treatment (SVR12). The emergence of any side effects was also monitored. RESULTS The most common risk factor (53.3%) was an parent or sibling with HCV infection. Twenty-nine patients (96.7%) were negative for HCV-RNA by week 2 of treatment and 1 patient became negative by week 4. The end of treatment response and SVR12 were 100%. Transaminases levels declined and returned to normal levels by week 2. Major side effects were fatigue in 90% (27/30) and headache in 76.7% (23/30). Side effects were minimal, tolerable, and did not interfere with daily activity or necessitate treatment discontinuation. CONCLUSIONS A shortened 8-week regimen of LED/SOF (45/200 mg) is safe and effective with 100% SVR12 in treatment-naïve children with cirrhosis aged 4-10 years with chronic HCV infection genotype 4.

Abstract
Background: New direct-acting antiviral drugs can eradicate hepatitis C virus (HCV) infection in over 90% of patients and can even reduce the risk of complications in advanced fibrosis/cirrhosis. The aims of this study were to evaluate (1) changes in fibrosis during and after antiviral treatment and (2) incidence of hepatocarcinoma and mortality in various fibrosis stages.Methods: This is a longitudinal monocentric prospective study. Blood and instrumental examinations were evaluated at baseline, at the end of therapy, and 1 and 2 years following treatment.Results: Two hundred and ninety-six patients with chronic HCV were evaluated, of whom 115 were experienced, 181 were treatment-naïve, and 2 had previous hepatocellular carcinoma (HCC) and were therefore excluded from the study. At baseline, stiffness values were 13.46 ± 9.97 kPa. Out of the 294 HCV patients enrolled, 100 had lymphoproliferative disorders and were evaluated separately. This group of patients showed stiffness values pertaining to the F0-F2 group (mean stiffness values were 6.07 ± 1.68 kPa). All other patients showed stiffness values pertaining to the F3-F4 group (mean stiffness values were 17.93 ± 10.23). No statistically significant difference was found between stiffness at baseline compared to the end of treatment (EOT), while significant differences were found between the baseline, 1 year (p = .05), and 2 year follow-ups (p < .01). Significant differences were found between baseline and EOT, as well as 1 and 2 years after the end of treatment (p < .001) in the F3-F4 group. Four out of 140 patients with baseline cirrhosis developed HCC during the post-treatment follow-up, 1 of whom died.Conclusions: Non-invasive methods provide important prognostic information, particularly concerning the observed regression of fibrosis and could be extremely useful for monitoring patients with long life expectancies after direct-acting antiviral treatment.

Abstract
UNLABELLED Background /Introduction: A high prevalence of type 2 diabetes mellitus (T2DM) was seen in association with hepatitis C virus infection; moreover, risk of development of T2DM is increased about 11 folds in patients with risk factors for metabolic syndrome in the presence of chronic hepatitis C virus (HCV) infection. There is a few available data on the effect of HCV eradication by the new direct-acting antiviral drugs (DAAs) on the glycemic control; hence the aim of our study is to evaluate the glycated haemoglobin (HbA1c) level changes in type 2 diabetic chronic HCV non cirrhotic treatment-naïve Egyptian patients after eradication with sofosbuvir (SOV) plus daclatasvir (DCV). PATIENTS AND METHODS A prospective observational cross-sectional study, included 128 type 2 diabetic HCV patients with easy to treat criteria (non cirrhotic treatment-naïve patients with the following liver biochemical markers; total serum bilirubin ≤ 1.2 mg/dl, serum albumin ≥ 3.5 g/dl, INR≤ 1.2 and Platelet count≥ 150.000/mm3); according to the protocol of the Egyptian National Committee for Controlling HCV and the guidelines of the European Association for the Study of the Liver. HbA1c was done for all patients enrolled in the study before starting antiviral treatment, at the end of treatment and 3 months (12 weeks) after the end of treatment to patients who achieved sustained virological response (SVR) 12 only. RESULTS According to their antidiabetic medications, patients were classified to Group I: 70 patients taking oral hypoglycemic drugs, Group II: 58 patients taking insulin therapy +/- oral hypoglycemic drugs. Regarding the glycemic profile, a statistically significant decrease of mean HbA1c % values was found in the studied patients (n=128), over the period of the study with p-value < 0.05. For better evaluation of improvement of glycemic control, we used a composite endpoint given by the reduction of HbA1c % (of a minimum of 0.5%). The endpoint was reached to 79% (101 patients) of all studied patients 3 months after the end of treatment. 75.7% (53 patients) reached the endpoint in group I, while 82.75 % (48 patients) of group II reached the endpoint 3 months after the end of treatment. CONCLUSION This study supports the idea that HCV eradication leads to a reduction in HbA1c in patients with diabetes, which could delay the onset and progression of microvascular diabetes complications.

Abstract
Infection with hepatitis C virus (HCV) is a major health problem worldwide. A large proportion of perinatal HCV infections are silent and may present later in adulthood with long-term complications. HCV has no effective immune prophylaxis and hence appropriate follow-up of all infants born to HCV-infected mothers is necessary. Universal antenatal screening for HCV is largely debatable. Intrauterine and partum transmission of HCV are both possible and higher rates are associated with a high maternal serum viral load (> 106 copies per milliliter), concomitant HIV infection, prolonged or difficult delivery, and invasive fetal monitoring during delivery. Infection during pregnancy and infancy needs to be investigated more in order to design management strategies for perinatal transmission of HCV most effectively. The recently approved new-generation, oral, direct-acting antiviral drugs may open a new era in HCV therapy for pregnant women and infected infants if proved to be safe during conception and infancy.

Abstract
Genetics of host plays a significant role in susceptibility and pathogenesis of disease. During hepatitis C virus (HCV) infection, HCV proteins interfere with interferon (IFN) signaling pathways and upregulate transcription of suppressor of cytokine signaling 1 and 3 genes (SOCS1 and SOCS3), which results in impaired immune response. In this study, we evaluated relative expression of SOCS1 and SOCS3 in untreated HCV patients and patients treated with 2 different treatment strategies that are, (IFN therapy and direct-acting antiviral (DAA) drug regimen. To study gene expression, peripheral blood mononuclear cells (PBMCs) were isolated by using Histopaque. Total RNA was extracted from PBMCs by using BIOzol. Nine microgram of total RNA from each sample was used and reverse transcribed into single-stranded complementary DNA (cDNA) by using M-MLV reverse transcriptase (Invitrogen). The synthesized cDNA was diluted to a final concentration of 500 ng/μL. This diluted cDNA was further used for expression analysis of SOCS1and SOCS3 genes using Rotor Gene Q Real-Time PCR Detection System (QIAGEN). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was amplified as a housekeeping gene. We found that the SOCS1 expression in IFN and DAA-treated patient groups was 5.4 fold and 1.2 fold, respectively, high compared with the healthy controls (IFN versus healthy, P = 0.019 and DAA versus healthy, P = 0.91), whereas the SOCS3 expression in IFN and DAA-treated patient groups was 3.7 fold and 2 fold, respectively, high in comparison with the expression in healthy controls (IFN versus healthy, P = 0.025 and DAA versus healthy, P = 0.03). We also found a significant difference in the relative expression of SOCS1 and SOCS3 in DAAs-treated and IFN/ribavirin (RBV)-treated and untreated individual. We concluded that by targeting HCV proteins with DAAs, SOCS1, and SOCS3 transcription can be more effectively normalized compared to the treatment with IFN/RBV therapy.

Abstract
Screening and treatment for hepatitis C virus (HCV) infection were not prioritised in psychiatric patients due to adverse neuropsychiatric effects of interferon therapy despite reports of high prevalence. However, with the safe new antiviral drugs, HCV eradication has become a reality in these patients. The aim of this study was to report HCV seroprevalence, risk factors and treatment model in an Australian cohort. This prospective study involved patients admitted to four inpatient psychiatric units, from December 2016 to December 2017. After pretest counselling and consent, HCV testing was done; information on risk factors collected. A total of 260 patients (70% male), median age 44 years (IQR 24), were studied. The HCV seroprevalence was 10.8% (28/260) with 95% CI 7-15. Independent predictors of HCV positivity were injection drug use (P < 0.001, OR 44.05, 95% CI 7.9-245.5), exposure to custodial stay (P = 0.011, OR 7.34, 95% CI 1.6-33.9) and age (P = 0.011, OR 1.09, 95% CI 1.02-1.16). Eight of the 16 HCV RNA-positive patients were treated. Hepatitis nurses liaised with community mental health teams for treatment initiation and follow-up under supervision of hepatologists. Seven patients achieved sustained viral response, one achieved end of treatment response. The remaining eight patients were difficult to engage with. In conclusion, HCV prevalence was high in our cohort of psychiatric inpatients. Although treatment uptake was achieved only in 50% patients, it was successfully completed in all, with innovative models of care. These findings highlight the need to integrate HCV screening with treatment linkage in psychiatry practice.

Abstract
Patients infected with hepatitis C virus (HCV) have an increased risk of developing type 2 diabetes. HCV infection is linked to various liver abnormalities, potentially contributing to this association. We show that HCV infection increases the levels of hepatic selenoprotein P (SeP) mRNA (SEPP1 mRNA) and serum SeP, a hepatokine linked to insulin resistance. SEPP1 mRNA inhibits type I interferon responses by limiting the function of retinoic-acid-inducible gene I (RIG-I), a sensor of viral RNA. SEPP1 mRNA binds directly to RIG-I and inhibits its activity. SEPP1 mRNA knockdown in hepatocytes causes a robust induction of interferon-stimulated genes and decreases HCV replication. Clinically, high SeP serum levels are significantly associated with treatment failure of direct-acting antivirals in HCV-infected patients. Thus, SeP regulates insulin resistance and innate immunity, possibly inducing immune tolerance in the liver, and its upregulation may explain the increased risk of type 2 diabetes in HCV-infected patients.

Abstract
Hepatitis C virus (HCV) is the most prevalent viral pathogen that infects more than 185 million people worldwide. HCV infection leads to chronic liver diseases such as liver cirrhosis and hepatocellular carcinoma. Direct-acting antivirals (DAAs) are the recent combination therapy for HCV infection with reduced side effects than prior therapies. Sustained virological response (SVR) acts as a gold standard marker to monitor the success of antiviral treatment. Older treatment therapies attain 50-55% of SVR compared with DAAs which attain around 90-95%. The current review emphasizes the recent chemogenomic updates that have been unfolded through structure-based drug design of HCV drug target proteins (NS3/4A, NS5A, and NS5B) and ligand-based drug design of DAAs in achieving a stable HCV viral treatment strategies.

Abstract
Objective Interferon-free regimens of direct-acting antiviral agents have improved the treatment response for chronic hepatitis C virus (HCV) infection, and improvement in the serum albumin level during interferon-free therapy has been reported. The aim of this study was to identify the factors that influence the improvement in the serum albumin level in patients receiving interferon-free antiviral therapy. Methods This retrospective, multicenter study consisted of 471 Japanese patients with chronic hepatitis and compensated liver cirrhosis infected with HCV who completed 12-week interferon-free sofosbuvir (SOF)-based therapy [SOF plus ledipasvir for genotype 1 (n=276) and SOF with ribavirin for genotype 2 (n=195)]. We evaluated the changes in the serum albumin level from baseline to the end of treatment (ΔAlb). Results When compared with the normal-albumin group (baseline serum albumin >35 g/L, n=406), the low-albumin group (baseline serum albumin ≤35 g/L, n=65) showed a significant increase in the mean ΔAlb (5.5 g/L vs. 1.0 g/L, p<0.001). In the low-albumin group, a multivariate logistic regression analysis extracted diabetes mellitus as a negative predictive factor of median ΔAlb >5.0 g/L (odds ratio: 0.19, 95% confidence interval: 0.048-0.79, p=0.020). In the low-albumin group, the mean ΔAlb was significantly lower in the diabetic patients (n=14) than in the non-diabetic patients (n=51) (3.9 g/L and 5.7 g/L, p=0.049). Conclusion Interferon-free SOF-based therapy significantly improved the serum albumin in the low-albumin group patients with chronic HCV infection. However, the improvement in the serum albumin level was significantly lower in the diabetic patients than in the non-diabetic patients.

Abstract
Given recent profound improvements in the effectiveness of antiviral treatment for chronic Hepatitis C virus (HCV) infection, we aimed to describe the characteristics of patients referred to hepatology expert centres in France from 2000 to 2007 and from 2010 to 2014, and to identify factors associated with severe liver disease at their first visit for evaluation. We analysed data from two sources covering all of France: the former hepatitis C surveillance network, which included patients between 2000 and 2007, and the ANRS CO22 HEPATHER multi-centre cohort, which included patients between 2012 and 2014. Severe liver disease (SLD) was defined as the presence of either cirrhosis (histological, biochemical or clinical) or hepatocellular carcinoma. Multivariable Poisson regression models were used to identify the factors associated with SLD in complete-case analysis and after multiple imputation. Overall, 16,851 patients were included in the analysis and SLD was diagnosed in 11.6%. SLD at first visit was significantly associated with known risk factors (male sex, history of excessive alcohol intake, HCV genotype 3), late referral to hepatologists after diagnosis and HCV diagnosis at an older age. Providing earlier specialised care and treatment may be an important target for public health action.

Abstract
AIM The development of direct-acting oral agents has dramatically changed the treatment strategy of hepatitis C virus (HCV) infection. Here we aimed to reveal the efficacy and safety of daclatasvir (DCV) and asunaprevir (ASV) for recurrent HCV genotype 1 infection after liver transplantation (LT). METHODS A retrospective study was undertaken on nine patients who underwent a 24-week DCV/ASV treatment regimen for recurrent HCV genotype 1 infection. Five of the patients were men; four had failed treatment with pegylated interferon (Peg-IFN)/ribavirin, two had failed simeprevir/Peg-IFN/ribavirin, one had the resistance-associated variant Y93H in the NS5A region, and one underwent maintenance dialysis. RESULTS Median time to treatment initiation following LT was 70 months. Of the nine patients treated with DCV/ASV, eight (88.9%) achieved a sustained viral response 12 weeks after completion of therapy (SVR12). The patient with virologic failure had failed simeprevir/Peg-interferon/ribavirin therapy 4 months before undergoing the DCV/ASV treatment regimen. In addition, a resistance-associated variant D168E in the NS3 region was detected in the patient after discontinuation of the DCV/ASV regimen. The trough level of tacrolimus tended to decrease, and renal function showed no significant changes during treatment. Adverse events occurred in two patients (22.2%), but no severe adverse events occurred during treatment. CONCLUSIONS The DCV/ASV regimen was well tolerated, resulting in high rates of sustained viral response 12 weeks after completion of therapy for LT patients with recurrent HCV genotype 1 infection.

Abstract
There are few descriptions of severe thrombocytopenia during the early postoperative period after liver transplantation, and these have not been fully documented in the literature. Here, we report a case of drug-induced thrombocytopenia requiring transfusion of blood products after living donor liver transplantation. We determined that this was not caused by the interferon-free anti-viral therapy but by tacrolimus A 61-year-old woman with hepatitis C-related cirrhosis and hepatorenal syndrome underwent living donor liver transplantation using a left lobe graft from her son. After transplantation, immunosuppression consisted of tacrolimus and steroid. Seven weeks after transplantation, interferon-free therapy with daclatasvir and asunaprevir was started. Thirteen days thereafter, hepatitis C virus tested negative. However, the platelet count had begun to gradually decrease just before starting anti-viral therapy. Daclatasvir and asunaprevir were stopped because this was suspected to be a side-effect of these drugs, but the patient nonetheless went on to develop severe thrombocytopenia (platelet count 17,000/μL), which needed transfusions. Now suspecting tacrolimus as the inducer of this side effect, we changed to cyclosporin, after which the platelet count gradually recovered. Viral markers were still not detectable up to 2 months after discontinuation of the antiviral drugs. We conclude that when severe thrombocytopenia occurs, possible drug-induced thrombocytopenia as well as other disorders must be investigated.

Abstract
INTRODUCTION Hepatitis C virus (HCV)-related liver disease is a cause of significant morbidity and mortality worldwide. Currently, direct-acting antiviral drugs (DAAs) are associated with an increased sustained virologic response (SVR) and are the gold standard for treating HCV infection. AREAS COVERED The new combination of grazoprevir, an inhibitor of HCV NS3/4A, and elbasvir, an inhibitor of HCV NS5A, once daily will be available for the treatment of HCV infection. This combination therapy has a high efficacy in HCV genotype 1 and 4 infections, inducing a SVR up to 95%, even in difficult to treat patients such as cirrhotic, HIV co-infected, or dialysis-dependent patients, and patients with stage 4-5 chronic kidney disease or those who failed previous therapy. The safety of grazoprevir combined with elbasvir is very good and without significant adverse effects in phase 2 or 3 studies. For patients who failed prior DAA therapy, in vitro and in vivo studies showed that the grazoprevir and elbasvir combination is fully active against resistance to NS3/4A protease inhibitors. Resistance to NS5B inhibitors is least susceptible to grazoprevir or elbasvir. EXPERT OPINION This new combination of gazoprevir with elbasvir offers an opportunity to cure HCV infection with short interferon-free therapy, even in difficult to treat patients.

Abstract
UNLABELLED Grazoprevir (MK-5172, Merck & Co., Inc.) is a selective inhibitor of the hepatitis C virus (HCV) NS3/4a protease. The aim of this study was to evaluate the safety and efficacy of grazoprevir at doses of 25-100 mg/day in combination with peginterferon and ribavirin (PEG-IFN/RBV). In this randomized, dose-ranging, multicentre trial, treatment-naive adults with chronic HCV genotype 1 infection received once-daily grazoprevir 25 mg, 50 mg or 100 mg plus PEG-IFN/RBV for 12 weeks. Patients with quantifiable HCV RNA (≥25 IU/mL) at week 4 received an additional 12 weeks of PEG-IFN/RBV. The primary endpoint was sustained virologic response (HCV RNA <25 IU/mL 12 weeks after completing therapy [SVR12]). Eighty-seven patients were randomly assigned and received ≥1 dose of therapy. Median time to undetectable HCV RNA was 16 days in the 100-mg arm and 22 days in the 25- and 50-mg arms. All patients except one had HCV RNA undetectable or unquantifiable at week 4 and received 12 weeks of therapy. SVR12 was achieved by 13 of 24 (54.2%), 21 of 25 (84.0%) and 23 of 26 (88.5%) patients in the 25-, 50- and 100-mg arms, respectively (per-protocol analysis). Three patients discontinued as a result of nonserious adverse events (AEs) and three patients experienced serious AEs. Transaminase elevations occurred in two patients (one each in the 25- and 100-mg arms). CONCLUSION These data support further study of the grazoprevir 100-mg dose. Phase 3 studies of grazoprevir 100 mg in combination with elbasvir are currently ongoing (NCT01710501; protocol P038).

Abstract
Direct-acting antiviral (DAA) drugs exhibit considerable variability in mechanisms of metabolism and the extent to which they are substrates, inhibitors, or inducers of cytochrome P450 enzymes or P-glycoprotein and other drug transporters. Thus, potential drug-drug interactions with other commonly used therapies also vary, as do the effects of renal and hepatic impairment on DAA drug exposure. Drug-drug interaction profiles and use in cases of renal or hepatic impairment are reviewed for the DAAs simeprevir; sofosbuvir; ledipasvir; the fixed-dose combination regimen of paritaprevir, ritonavir, and ombitasvir plus dasabuvir; and the investigational drugs daclatasvir and asunaprevir. This article summarizes a presentation by Lucas Hill, PharmD, at the IAS-USA continuing education program held in Chicago, Illinois, in October 2014.
