Work HM, Hackett JC, Lampe JN. HCV Antiviral Drugs Have the Potential to Adversely Perturb the Fetal-Maternal Communication Axis through Inhibition of CYP3A7 DHEA-S Oxidation. Drug Metab Dispos 2024; 52:516-525. [PMID: 38267095 PMCID: PMC11114604 DOI: 10.1124/dmd.123.001434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 12/21/2023] [Accepted: 01/19/2024] [Indexed: 01/26/2024] Open
Abstract
The hepatitis C virus (HCV) poses a great risk to pregnant people and their developing fetus, yet no HCV antiviral treatment guidelines have been established. While there has been a substantial increase in the development of HCV antivirals, the effect they have on the developing fetus remains poorly defined. Many of these drugs are metabolized through the cytochrome P450 CYP3A pathway, which is mediated by cytochrome P450 3A7 (CYP3A7) in the fetus and developing infant. In this study, we sought to investigate the effect HCV antivirals have on CYP3A7 metabolism, as this CYP enzyme plays a vital role in proper fetal and neonatal development. Of the 13 HCV antivirals we investigated, 8 (∼62%) inhibited CYP3A7 metabolic activity by 50% or more at a concentration of 20 µM. Furthermore, paritaprevir, asunaprevir, simeprevir, danoprevir, and glecaprevir all had observed half-maximal inhibitory concentrations between the range of 10 and 20 µM, which is physiologically relevant in comparison with the Km of dehydroepiandrosterone-sulfate (DHEA-S) oxidation (reported to be between 5 and 20 µM). We also discovered that paritaprevir is a time-dependent inhibitor of CYP3A7, which shifts the IC50 ∼twofold from 11 µM to 5 µM. Upon further characterization, paritaprevir inactivates DHEA-S metabolism by CYP3A7, with KI and Kinact values of 4.66 µM and 0.00954 minute-1, respectively. Depending on treatment plan and off-label drug use, HCV treatment could adversely affect the fetal-maternal communication axis by blocking fetal CYP3A7 metabolism of important endogenous hormones. SIGNIFICANCE STATEMENT: The prevalence of HCV in pregnant people is estimated at between 1% and 8% of the global population, yet little to no information exists about the risk antiviral treatment poses to the developing fetus. There is a potential risk of drugs adversely affecting mother-fetal communication by inhibiting fetal hepatic CYP3A7, an integral enzyme for estriol production. We discovered that five HCV antivirals inhibited DHEA-S metabolism by CYP3A7, and paritaprevir inactivated the enzyme. Our studies demonstrate the potential threat these drugs pose to proper fetal development.

Abstract
Hepatitis C virus (HCV) represents a formidable menace to human health, necessitating urgent attention. The objective of this study was to assess the efficacy and safety of HCV health management in the city of Guigang which consists of five districts, employing a comprehensive multi-modal approach. The study systematically carried out HCV screening in Guigang city which consists of five districts, such as Gangbei District, Gangnan District, Guiping District, Qintang District, and Pingnan District from 1 January 2016 to 30 December 2022. The target population consisted of individuals residing in these aforementioned districts, falling within the age range of 30-75 years. A multidisciplinary HCV management team was established to deliver anti-HCV screening, diagnosis, and direct-acting antiviral (DAA) therapy. The primary outcome of interest was the achievement of sustained virologic response (SVR). A total of 2489 individuals were included as the target population, with 1694 individuals residing in Gangbei District, 202 in Gangnan District, 111 in Qintang District, 167 in Pingnan District, and 315 in Guiping District. Out of these individuals, 2478 were subjected to anti-HCV screening. The screening rates varied across the districts, ranging from a peak of 99.55% in Guigang City to a nadir of 98.41% in Guiping District. Remarkably, within Guigang City, a noteworthy enhancement was observed in the HCV-RNA diagnosis rate from 23.4% prior to program implementation to a remarkable 100% following 7 years of intervention and management. Furthermore, the diagnosis and treatment coordination rate experienced a substantial improvement, rising from 26.8% before program inception to 80%. Importantly, a total of 1180 individuals affected by hepatitis C were successfully cured, equating to a 100% cure rate. Logistic regression analysis revealed a significant association between serological status and factors such as Aging, bilirubin, and glutamic oxalacetic transaminase. The findings from our investigation unveil a pioneering HCV management model, exemplified by the Guigang model, which has contributed crucially to HCV microclearance efforts and serves as an invaluable reference for future initiatives.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) management in Inflammatory Bowel Disease (IBD) is uncertain. The ECCO guidelines 2021 recommended HCV treatment but warn about the risk of IBD reactivation. We aimed to evaluate 1) the effectiveness and safety of direct-acting antivirals (DAAs) in IBD; 2) the interaction of DAAs with IBD drugs. METHODS Multicentre study of IBD patients and HCV treated with DAAs. Variables related to liver diseases and IBD, as well as adverse events (AEs) and drug interactions, were recorded. McNemar's test was used to assess differences in the proportion of active IBD during the study period. RESULTS We included 79 patients with IBD and HCV treated with DAAs from 25,998 IBD patients of the ENEIDA registry. Thirty-one (39.2 %) received immunomodulators/biologics. There were no significant differences in the percentage of active IBD at the beginning (n = 11, 13.9 %) or at the 12-week follow-up after DAAs (n = 15, 19 %) (p = 0.424). Sustained viral response occurred in 96.2 % (n = 76). A total of 8 (10.1 %) AEs occurred and these were unrelated to activity, type of IBD, liver fibrosis, immunosuppressants/biologics, and DAAs. CONCLUSIONS We demonstrate a high efficacy and safety of DAAs in patients with IBD and HCV irrespective of activity and treatment of IBD.

Clin Ther 2024; 46:e12-e22. [PMID: 37925363 DOI: 10.1016/j.clinthera.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 10/08/2023] [Accepted: 10/09/2023] [Indexed: 11/06/2023]
Abstract
PURPOSE Children with hematological malignancies and chronic hepatitis C virus (HCV) infection are at a higher risk for rapid progression of liver disease and malignancy relapse due to multiple hepatitis flares and chemotherapy interruption. They are therefore potential candidates for microelimination of HCV infection. This study aimed to assess the effect of acute lymphoblastic leukemia (ALL) on the pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF) and the SOF major metabolite GS-331007. METHODS This was a 24-week, prospective, controlled, open-label, 2-arm PK study of patients receiving 45/200 mg once-daily LDV/SOF orally for 12 weeks. Eligible patients were HCV-RNA-positive, treatment-naive children aged 6 to <12 years and/or weighing 17 to <35 kg with genotype 4 chronic HCV infection without cirrhosis. The primary efficacy and safety end points were the achievement of sustained virologic response for all patients with absence of any adverse events leading to permanent discontinuation of the study drug. Steady-state noncompartmental analysis was performed to determine the PK parameters of SOF, GS-331007, and LDV as the primary PK outcome. Dose suitability was based on the 90% CI of exposure geometric mean ratio percentage within 50% to 200% compared with adults. FINDINGS Ten HCV-infected children with ALL (chemotherapy treatment group) and 12 eligible children with no malignancy (control group) were enrolled and completed the study period. All 22 patients achieved the sustained virologic response with no adverse events leading to interruption or permanent discontinuation of the study drug. Compared with the control group, the ALL group patients had similar SOF, GS-331007, and LDV exposure. Compared with adults, the AUCτ of GS-331007 was lower and the AUCτ and Cmax,ss of SOF and the Cmax,ss of LDV were modestly higher in the ALL group (acceptance limit, 50%-200%). However, the observed efficacy and favorable safety profile made these changes not clinically significant. IMPLICATIONS Weight-based dosing of LDV/SOF (45/200 mg) is highly effective and safe among genotype 4 HCV-infected children weighing 17 to <35 kg and diagnosed with ALL undergoing maintenance chemotherapy. The similarity in the drug exposure, efficacy, and safety clinical end points between patients with and without hematological malignancy support their therapeutic equivalence. Further studies with a larger sample size may be required to confirm the safety of LDV/SOF in patients with ALL and to recommend appropriate dosing in children with hematological malignancies, if needed.

Abstract
INTRODUCTION The World Health Organization proposed targets to eliminate hepatitis C virus (HCV) by 2030, aiming to treat ≥80% of people with HCV, decreasing new chronic infections by 90% and liver-related mortality by 65%. While children/adolescents represent a minority of cases, the true burden is underestimated. Advances in drug development have resulted in simplified treatments that are well-tolerated, effective, and pangenotypic in activity. Sofosbuvir/velpatasvir, a combined nucleotide analog NS5B polymerase inhibitor and NS5A inhibitor, respectively, is approved for HCV treatment for individuals ≥3 years, supported by safety data using lower-dose, novel formulations. AREAS COVERED This review discusses chemistry, pharmacokinetics/pharmacodynamics, dosing, efficacy, and safety of sofosbuvir/velpatasvir highlighting pediatric data. Literature review included publications/conference abstracts from PubMed, Google, and Google Scholar. Information from key clinical trials/regulatory approvals is reviewed. EXPERT OPINION Sofosbuvir/velpatasvir is a safe and effective therapy for the treatment of pangenotypic chronic HCV infection with limited cases of virologic relapse and adverse events among pediatric populations aged 3 years and older. However, the tolerability among children less than 6 years could be improved by alternative formulations, if not, shorter treatment durations. An aspirational role of direct-acting antivirals (DAAs) that should be explored is for the prevention of infection in exposed and at-risk pediatric populations.

Abstract
The treatment of patients infected with the hepatitis C virus (HCV) has been revolutionised by the development of direct-acting antiviral agents (DAAs) that target specific HCV proteins involved in viral replication. The first DAAs were associated with clinical problems such as adverse drug reactions and pharmacokinetic drug-drug interactions (DDIs). Current FDA/EMA-approved treatments are combinations of DAAs that simultaneously target the HCV N5A-protein, the HCV N5B-polymerase and the HCV NS3/4A-protease. Adverse events and DDIs are less likely with these DAA combinations but several DDIs of potential clinical significance remain. Much of the available information on the interaction of DAAs with CYP drug-metabolising enzymes and influx and efflux transporters is contained in regulatory summaries and is focused on DDIs of likely clinical importance. Important DDIs perpetrated by current DAAs include increases in the pharmacokinetic exposure to statins and dabigatran. Some mechanistic information can be deduced. Although the free concentrations of DAAs in serum are very low, a number of these DDIs are likely mediated by the inhibition of systemic influx transporters, especially OATP1B1/1B3. Other DDIs may arise by DAA-mediated inhibition of intestinal efflux transporters, which increases the systemic concentrations of some coadministered drugs. Conversely, DAAs are victims of DDIs mediated by cyclosporin, ketoconazole, omeprazole and HIV antiretroviral drug combinations, especially when boosted by ritonavir and, to a lesser extent, cobicistat. In addition, concurrent administration of inducers, such as rifampicin, carbamazepine and efavirenz, decreases exposure to some DAAs. Drug-drug interactions that increase the accumulation of HCV N3/4A-protease inhibitors like grazoprevir may exacerbate hepatic injury in HCV patients.

Abstract
Hepatitis C virus (HCV) infection is more prevalent in people living with HIV-AIDS (PLHA) and portends a poorer prognosis. Pharmacokinetic studies suggest the absence of significant interaction between velpatasvir and dolutegravir which has been recently recommended as part of preferred first-line antiretroviral therapy (ART) regimens by WHO. However, clinical data on the use of velpatasvir-based regimen in PLHA taking dolutegavir is lacking. Hence, we aimed to assess the efficacy and safety of sofosbuvir and velpatasvir (SOF + VEL) in HCV and HIV coinfected patients on dolutegravir-based ART. Forty-five consecutive PLHA with HCV coinfection on dolutegravir-based ART were prospectively enrolled. All patients were treated SOF + VEL for 12 weeks. Complete haemogram, liver and renal function tests were assessed at baseline, 4 weeks and at end of treatment. Sustained virological response (SVR) was assessed at 12 weeks after end of treatment. The majority were males (95.5%) with a mean age of 32.8 ± 12.3 years. Cirrhosis was present in 6 (13.3%) patients. All patients completed 12 weeks of therapy with SOF + VEL, but SVR could not be assessed in two patients. Forty-two (97.7%) of the remaining 43 patients attained SVR-12. SVR-12 rate was 97.7% and 93.3% by per protocol and intention to treat analysis, respectively. No grade III/IV adverse events were reported, and there was no worsening of blood counts, liver or renal function test parameters. The pan-genotypic regimen of SOF + VEL is safe and effective in PLHA with HCV coinfection who are on dolutegravir-based ART.

Preemptive antiviral therapy in lung transplantation from hepatitis C donors results in a rapid and sustained virologic response. JTCVS OPEN 2023; 14:602-614. [PMID: 37425441 PMCID: PMC10328796 DOI: 10.1016/j.xjon.2023.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 02/04/2023] [Accepted: 02/16/2023] [Indexed: 07/11/2023]
Abstract
Objective The study objective was to assess the safety and efficacy of a preemptive direct-acting antiviral therapy in lung transplants from hepatitis C virus donors to uninfected recipients. Methods This study is a prospective, open-label, nonrandomized, pilot trial. Recipients of hepatitis C virus nucleic acid test positive donor lungs underwent preemptive direct-acting antiviral therapy with glecaprevir 300 mg/pibrentasvir 120 mg for 8 weeks from January 1, 2019, to December 31, 2020. Recipients of nucleic acid test positive lungs were compared with recipients of lungs from nucleic acid test negative donors. Primary end points were Kaplan-Meier survival and sustained virologic response. Secondary outcomes included primary graft dysfunction, rejection, and infection. Results Fifty-nine lung transplantations were included: 16 nucleic acid test positive and 43 nucleic acid test negative. Twelve nucleic acid test positive recipients (75%) developed hepatitis C virus viremia. Median time to clearance was 7 days. All nucleic acid test positive patients had undetectable hepatitis C virus RNA by week 3, and all alive patients (n = 15) remained negative during follow-up with 100% sustained virologic response at 12 months. One nucleic acid test positive patient died of primary graft dysfunction and multiorgan failure. Three of 43 nucleic acid test negative patients (7%) had hepatitis C virus antibody positive donors. None of them developed hepatitis C virus viremia. One-year survival was 94% for nucleic acid test positive recipients and 91% for nucleic acid test negative recipients. There was no difference in primary graft dysfunction, rejection, or infection. One-year survival for nucleic acid test positive recipients was similar to a historical cohort of the Scientific Registry of Transplant Recipients (89%). Conclusions Recipients of hepatitis C virus nucleic acid test positive lungs have similar survival as recipients of nucleic acid test negative lungs. Preemptive direct-acting antiviral therapy results in rapid viral clearance and sustained virologic response at 12 months. Preemptive direct-acting antiviral may partially prevent hepatitis C virus transmission.

Protein Abundance of Drug Metabolizing Enzymes in Human Hepatitis C Livers. Int J Mol Sci 2023; 24:ijms24054543. [PMID: 36901973 PMCID: PMC10002520 DOI: 10.3390/ijms24054543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/22/2023] [Accepted: 02/22/2023] [Indexed: 03/02/2023] Open
Abstract
Hepatic drug metabolizing enzymes (DMEs), whose activity may be affected by liver diseases, are major determinants of drug pharmacokinetics. Hepatitis C liver samples in different functional states, i.e., the Child-Pugh class A (n = 30), B (n = 21) and C (n = 7) were analyzed for protein abundances (LC-MS/MS) and mRNA levels (qRT-PCR) of 9 CYPs and 4 UGTs enzymes. The protein levels of CYP1A1, CYP2B6, CYP2C8, CYP2C9, and CYP2D6 were not affected by the disease. In the Child-Pugh class A livers, a significant up-regulation of UGT1A1 (to 163% of the controls) was observed. The Child-Pugh class B was associated with down-regulation of the protein abundance of CYP2C19 (to 38% of the controls), CYP2E1 (to 54%), CYP3A4 (to 33%), UGT1A3 (to 69%), and UGT2B7 (to 56%). In the Child-Pugh class C livers, CYP1A2 was found to be reduced (to 52%). A significant trend in down-regulation of the protein abundance was documented for CYP1A2, CYP2C9, CYP3A4, CYP2E1, UGT2B7, and UGT2B15. The results of the study demonstrate that DMEs protein abundances in the liver are affected by hepatitis C virus infection and depend on the severity of the disease.

Use of contraindicated antiretroviral drugs in people with HIV/HCV coinfections receiving HCV treatment with direct-acting antivirals-Results from the EuroSIDA study. HIV Med 2023; 24:224-230.

Abstract
OBJECTIVES Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study. METHODS At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs. RESULTS Among 1406 people starting DAAs, the median age was 51 years, 75% were male, 57% reported injected drug use as an HIV risk, and 76% were from western Europe. Of 1624 treatment episodes, 609 (37.5%) occurred while the patient was receiving ARVs with potential contraindications; among them, 38 (6.2%; 95% confidence interval [CI] 4.3-8.2) involved a contraindicated ARV (18 non-nucleoside reverse transcriptase inhibitors), 16 involved protease inhibitors, and four involved integrase strand transfer inhibitors. The adjusted odds of receiving a contraindicated ARV were higher (3.25; 95% CI 1.40-7.57) among participants from east/central east Europe (vs. south) and lower (0.22; 95% CI 0.08-0.65) for 2015-2018 guidelines (vs. 2014). In total, 29 of the 32 (90.6%) patients receiving a contraindicated ARV and 441 of the 461 (95.7%) with potential ARV contraindications experienced a sustained virological response ≥12 weeks after stopping treatment (SVR12; p = 0.55). CONCLUSION In this large heterogenous European cohort, more than one-third of people with HIV/HCV coinfection received DAAs with potential ARV contraindications, but few received a contraindicated ARV. Use of contraindicated ARVs declined over time, corresponding to the increased availability of ARV therapy regimens without interactions with DAA across Europe. Participants who received a contraindicated DAA and ARV combination still had a high rate of SVR12.

Abstract
Background World Health Organization has called for research into predictive factors for selecting persons who could be successfully treated with shorter durations of direct-acting antiviral (DAA) therapy for hepatitis C. We evaluated early virological response as a means of shortening treatment and explored host, viral and pharmacokinetic contributors to treatment outcome. Methods Duration of sofosbuvir and daclatasvir (SOF/DCV) was determined according to day 2 (D2) virologic response for HCV genotype (gt) 1- or 6-infected adults in Vietnam with mild liver disease. Participants received 4- or 8-week treatment according to whether D2 HCV RNA was above or below 500 IU/ml (standard duration is 12 weeks). Primary endpoint was sustained virological response (SVR12). Those failing therapy were retreated with 12 weeks SOF/DCV. Host IFNL4 genotype and viral sequencing was performed at baseline, with repeat viral sequencing if virological rebound was observed. Levels of SOF, its inactive metabolite GS-331007 and DCV were measured on days 0 and 28. Results Of 52 adults enrolled, 34 received 4 weeks SOF/DCV, 17 got 8 weeks and 1 withdrew. SVR12 was achieved in 21/34 (62%) treated for 4 weeks, and 17/17 (100%) treated for 8 weeks. Overall, 38/51 (75%) were cured with first-line treatment (mean duration 37 days). Despite a high prevalence of putative NS5A-inhibitor resistance-associated substitutions (RASs), all first-line treatment failures cured after retreatment (13/13). We found no evidence treatment failure was associated with host IFNL4 genotype, viral subtype, baseline RAS, SOF or DCV levels. Conclusions Shortened SOF/DCV therapy, with retreatment if needed, reduces DAA use in patients with mild liver disease, while maintaining high cure rates. D2 virologic response alone does not adequately predict SVR12 with 4-week treatment.

Abstract
To address the continued rise of multi-drug-resistant microorganisms, the development of novel drugs with new modes of action is urgently required. While humans biosynthesize the essential isoprenoid precursors isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) via the established mevalonate pathway, pathogenic protozoa and certain pathogenic eubacteria use the less well-known methylerythritol phosphate pathway for this purpose. Important pathogens using the MEP pathway are, for example, Plasmodium falciparum, Mycobacterium tuberculosis, Pseudomonas aeruginosa and Escherichia coli. The enzymes of that pathway are targets for antiinfective drugs that are exempt from target-related toxicity. 2C-Methyl-D-erythritol 4-phosphate (MEP), the second enzyme of the non-mevalonate pathway, has been established as the molecular target of fosmidomycin, an antibiotic that has so far failed to be approved as an anti-infective drug. This review describes the development and anti-infective properties of a wide range of fosmidomycin derivatives synthesized over the last four decades. Here we discuss the DXR inhibitor pharmacophore, which comprises a metal-binding group, a phosphate or phosphonate moiety and a connecting linker. Furthermore, non-fosmidomycin-based DXRi, bisubstrate inhibitors and several prodrug concepts are described. A comprehensive structure-activity relationship (SAR) of nearly all inhibitor types is presented and some novel opportunities for further drug development of DXR inhibitors are discussed.

Abstract
The coronavirus disease 2019 (COVID-19) antiviral nirmatrelvir/ritonavir (Paxlovid) has been granted authorization or approval in several countries for the treatment of patients with mild to moderate COVID-19 at high risk of progression to severe disease and with no requirement for supplemental oxygen. Nirmatrelvir/ritonavir will be primarily administered outside the hospital setting as a 5-day course oral treatment. The ritonavir component boosts plasma concentrations of nirmatrelvir through the potent and rapid inhibition of the key drug-metabolizing enzyme cytochrome P450 (CYP) 3A4. Thus nirmatrelvir/ritonavir, even given as a short treatment course, has a high potential to cause harm from drug-drug interactions (DDIs) with other drugs metabolized through this pathway. Options for mitigating risk from DDIs with nirmatrelvir/ritonavir are limited due to the clinical illness, the short window for intervention, and the related difficulty of implementing clinical monitoring or dosage adjustment of the comedication. Pragmatic options are largely confined to preemptive or symptom-driven pausing of the comedication or managing any additional risk through counseling. This review summarizes the effects of ritonavir on drug disposition (i.e., metabolizing enzymes and transporters) and discusses factors determining the likelihood of having a clinically significant DDI. Furthermore, it provides a comprehensive list of comedications likely to be used in COVID-19 patients which are categorized according to their potential DDI risk with nirmatrelvir/ritonavir. It also discusses recommendations for the management of DDIs which balance the risk of harm from DDIs with a short course of ritonavir, against unnecessary denial of nirmatrelvir/ritonavir treatment.

Abstract
Sofosbuvir (SOF), a nucleotide inhibitor of the hepatitis C virus (HCV) polymerase, is a component of several all-oral HCV therapies. GS-331007, SOF's predominant metabolite, is renally eliminated and accumulates 5- to 20-fold in patients with advanced chronic kidney disease (CKD) or undergoing hemodialysis (HD), respectively. Preclinical data did not determine whether these exposures represented a risk for toxicity. Therefore subjects with advanced CKD were not included in registrational studies and SOF was not initially approved for use in advanced CKD. Nevertheless, after initial licensing, off-label use of SOF at full or reduced doses was reported in patients with kidney disease. Two clinical trials of SOF-containing therapies were conducted in patients with end-stage kidney disease, demonstrating safety and efficacy. These led to expanded US Food and Drug Administration approval in 2019 for the use of SOF-containing regimens in patients with advanced CKD, including dialysis dependence. Even so, given the availability of protease inhibitor-containing direct-acting antiviral regimens, there was a reluctance by some practitioners to use SOF-containing regimens in moderate to severe kidney disease. Here we review the existing data on SOF's pharmacokinetics, toxicology, efficacy and safety in patients with kidney disease. Data from both clinical trials and real-world practice settings indicate that in patients with moderate to severe kidney disease, full-dose SOF-based regimens have high rates of efficacy and acceptable safety and tolerability profiles, without increased risk for cardiac adverse events or clinically meaningful changes in kidney function. SOF-based regimens are safe and effective in patients who have moderate to severe kidney disease, including those undergoing HD.

Abstract
Transmembrane drug transport in hepatocytes is one of the major determinants of drug pharmacokinetics. In the present study, ABC transporters (P-gp, MRP1, MRP2, MRP3, MRP4, BCRP, and BSEP) and SLC transporters (MCT1, NTCP, OAT2, OATP1B1, OATP1B3, OATP2B1, OCT1, and OCT3) were quantified for protein abundance (LC-MS/MS) and mRNA levels (qRT-PCR) in hepatitis C virus (HCV)-infected liver samples from the Child–Pugh class A (n = 30), B (n = 21), and C (n = 7) patients. Protein levels of BSEP, MRP3, MCT1, OAT2, OATP1B3, and OCT3 were not significantly affected by HCV infection. P-gp, MRP1, BCRP, and OATP1B3 protein abundances were upregulated, whereas those of MRP2, MRP4, NTCP, OATP2B1, and OCT1 were downregulated in all HCV samples. The observed changes started to be seen in the Child–Pugh class A livers, i.e., upregulation of P-gp and MRP1 and downregulation of MRP2, MRP4, BCRP, and OATP1B3. In the case of NTCP, OATP2B1, and OCT1, a decrease in the protein levels was observed in the class B livers. In the class C livers, no other changes were noted than those in the class A and B patients. The results of the study demonstrate that drug transporter protein abundances are affected by the functional state of the liver in hepatitis C patients.

Abstract
Background: With the development of direct-acting antiviral agents (DAAs), the research on kidney transplantation from Hepatitis C virus (HCV)-viremic donors to HCV-negative recipients has grown. The objective of this comprehensive analysis was to evaluate the efficacy and safety of DAAs in kidney transplantation from HCV-viremic donors to negative recipients. Methods Multiple databases were searched for a systematic and comprehensive up to March 2022. The primary outcomes included the percentage of sustained virological response at week 12 after the end of treatment (SVR12), adverse events (AEs; any grade), and severe adverse events (SAEs) as the endpoints. Publication bias was examined by using the funnel plots and Egger's test. Results In total, 16 studies with 454 subjects were included in the study and the pooled estimate of SVR12, AEs, and SAEs rates were 100.0% (95% CI: 99.2-100.0), 1.9%(95%CI: 0.0-4.9), and 0.0% (95%CI: 0.0-1.5). Subgroup analysis showed that pooled SVR12 rates were 100.0% (95%CI: 99.6-100.0) for genotype (GT)1a and 96.3% (95%CI: 83.3-100.0) for GT2; 100.0% (95%CI: 98.9-100.0) for DAAs treatments; and 100.0% (95%CI: 98.2-100.0) for prophylaxis subgroup. Egger's tests showed that no publication bias was found in this study. Conclusion This comprehensive analysis showed the high efficacy and safety of DAAs in kidney transplantation from HCV-viremic donors to HCV-negative recipients.

Abstract
The use of hepatitis C virus (HCV) -positive organs in HCV-negative recipients with posttransplant antiviral treatment has increasingly been studied since the introduction of new direct-acting antivirals. This article reviews existing experience in liver and kidney transplant. Fifteen studies with 218 HCV D+/R- liver transplants, with 182 from viremic donors, show a sustained viral response for 12 weeks (SVR12) rate of 99.5%. Nine studies involving 204 HCV donor-positive recipient-negative kidney transplant recipients had an SVR12 rate of 99.5%. Complications are infrequent. Preemptive treatment in kidney transplant of for only 4 weeks or even 4 days showed surprising success rates.

Abstract
With a globally estimated 58 million people affected by, chronic hepatitis C virus (HCV) infection still represents a hard challenge for scientific community. A chronic course can occur among patients with a weak innate ad adaptive response with cirrhosis and malignancies as main consequences. Oncologic patients undergoing chemotherapy represent a special immunocompromised population predisposed to HCV reactivation (HCVr) with undesirable changes in cancer treatment and outcome. Aim of the study highlight the possibility of HCVr in oncologic population eligible to chemotherapy and its threatening consequences on cancer treatment; underline the importance of HCV screening before oncologic therapy and the utility of direct aging antivirals (DAAs). A comprehensive overview of scientific literature has been made. Terms searched in PubMed were: “HCV reactivation in oncologic setting” “HCV screening”, “second generation DAAs”. Pharmacokinetic and Pharmacodynamics characteristics of DAAs are reported, along with drug - drug interactions among chemotherapeutic drug classes regimens and DAAs. Clinical trials conducted among oncologic adults with HCV infection eligible to both chemotherapy and DAAs were analyzed. Viral eradication with DAAs in oncologic patients affected by HCV infection is safe and helps liver recovery, allowing the initiation of cancer treatment no compromising its course and success.

Real-World Effectiveness of Direct-Acting Antiviral Regimens against Hepatitis C Virus (HCV) Genotype 3 Infection: A Systematic Review and Meta-Analysis. Ann Hepatol 2022; 23:100268. [PMID: 33059055 DOI: 10.1016/j.aohep.2020.09.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 09/16/2020] [Accepted: 09/21/2020] [Indexed: 02/04/2023]
Abstract
Patients with hepatitis C virus (HCV) genotype 3 (GT3) infection are resistant to direct-acting antiviral (DAA) treatments. This study aimed to analyze the effectiveness of sofosbuvir (SOF)+daclatasvir (DCV) ± ribavirin (RBV); SOF+velpatasvir (VEL)±RBV; SOF+VEL+voxilaprevir (VOX); and glecaprevir (GLE)+pibrentasvir (PIB) in the treatment of HCV GT3-infected patients in real-world studies. Articles were identified by searching the PubMed, EMBASE, and Cochrane Library databases from January 1, 2016 to September 10, 2019. The meta-analysis was conducted to determine the sustained virologic response (SVR) rate, using R 3.6.2 software. Thirty-four studies, conducted on a total of 7328 patients from 22 countries, met the inclusion criteria. The pooled SVR rate after 12/24 weeks of treatment was 92.07% (95% CI: 90.39-93.61%) for the evaluated regimens. Also, the SVR rate was 91.17% (95% CI: 89.23-92.94%) in patients treated with SOF+DCV±RBV; 95.08% (95% CI: 90.88-98.13%) in patients treated with SOF+VEL±RBV; 84.97% (95% CI: 73.32-93.91%) in patients treated with SOF+VEL+VOX; and 98.54% (95% CI: 96.40-99.82%) in patients treated with GLE+PIB. The pooled SVR rate of the four regimens was 95.24% (95% CI: 93.50-96.75%) in non-cirrhotic patients and 89.39% (95% CI: 86.07-92.33%) in cirrhotic patients. The pooled SVR rate was 94.41% (95% CI: 92.02-96.42%) in treatment-naive patients and 87.98% (95% CI: 84.31-91.25%) in treatment-experienced patients. The SVR rate of GLE+PIB was higher than other regimens. SOF+VEL+VOX can be used as a treatment regimen following DAA treatment failure.

Protease inhibitor-based direct-acting antivirals are associated with increased risk of aminotransferase elevations but not hepatic dysfunction or decompensation. J Hepatol 2021; 75:1312-1322. [PMID: 34333102 PMCID: PMC8604762 DOI: 10.1016/j.jhep.2021.07.021] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 07/14/2021] [Accepted: 07/18/2021] [Indexed: 12/04/2022]
Abstract
BACKGROUND & AIMS Cases of acute liver injury (ALI) have been reported among chronic HCV-infected patients receiving protease inhibitor (PI)-based direct-acting antiviral (DAA) regimens, but no analyses have compared the risk of ALI in patients receiving PI- vs. non-PI-based DAAs. Thus, we compared the risk of 3 ALI outcomes between patients (by baseline Fibrosis-4 [FIB-4] group) receiving PI-based or non-PI-based DAAs. METHODS We conducted a cohort study of 18,498 patients receiving PI-based DAA therapy (paritaprevir/ritonavir/ombitasvir±dasabuvir, elbasvir/grazoprevir, glecaprevir/pibrentasvir) matched 1:1 on propensity score to those receiving non-PI-based DAAs (sofosbuvir/ledipasvir, sofosbuvir/velpatasvir) in the 1945-1965 Veterans Birth Cohort (2014-2019). During exposure to DAA therapy, we determined development of: i) alanine aminotransferase (ALT) >200 U/L, ii) severe hepatic dysfunction (coagulopathy with hyperbilirubinemia), and iii) hepatic decompensation. We used Cox regression to determine hazard ratios (HRs) with 95% CIs for each ALI outcome within groups defined by baseline FIB-4 (≤3.25; >3.25). RESULTS Among patients with baseline FIB-4 ≤3.25, those receiving PIs had a higher risk of ALT >200 U/L (HR 3.98; 95% CI 2.37-6.68), but not severe hepatic dysfunction (HR 0.67; 95% CI 0.19-2.39) or hepatic decompensation (HR 1.01; 95% CI 0.29-3.49), compared to those receiving non-PI-based regimens. For those with baseline FIB-4 >3.25, those receiving PIs had a higher risk of ALT >200 U/L (HR, 2.15; 95% CI 1.09-4.26), but not severe hepatic dysfunction (HR, 1.23 [0.64-2.38]) or hepatic decompensation (HR, 0.87; 95% CI 0.41-1.87), compared to those receiving non-PI-based regimens CONCLUSION: While risk of incident ALT elevations was increased in those receiving PI-based DAAs in both FIB-4 groups, the risk of severe hepatic dysfunction and hepatic decompensation did not differ between patients receiving PI- or non-PI-based DAAs in either FIB-4 group. LAY SUMMARY Cases of liver injury have been reported among patients treated with protease inhibitor-based direct-acting antivirals for hepatitis C infection, but it is not clear if the risk of liver injury among people starting these drugs is increased compared to those starting non-protease inhibitor-based therapy. In this study, patients receiving protease inhibitor-based treatment had a higher risk of liver inflammation than those receiving a non-protease inhibitor-based treatment, regardless of the presence of pre-treatment advanced liver fibrosis/cirrhosis. However, the risk of severe liver dysfunction and decompensation were not higher for patients treated with protease inhibitor-based regimens.

Abstract
Trials describing 4- to 12-week courses of direct-acting antiviral drugs (DAAs) to treat hepatitis C virus (HCV) transmission from infected donors to uninfected kidney transplant recipients (D+/R- transplants) may be limited in "real-world" application by costs and delayed access to DAAs. We previously reported HCV transmission of 13% among D+/R- transplants with 2- to 4-day pangenotypic sofosbuvir/velpatasvir (SOF/VEL) perioperative prophylaxis, where one patient with HCV transmission was a nonresponder to first-line full-course DAA. Here, we report new data with a 7-day prophylaxis protocol (N = 50), as well as cumulative treatment and outcome data on all HCV D+/R- transplants (N = 102). Overall, nine patients (9/102; 9%; 95% CI: 5%-16%) developed HCV transmission, with a significant decline noted in the 7-day group (2/50; 4%; 95% CI: 0%-13%) compared with 2- to 4-day prophylaxis (7/52; 13%; 95% CI: 5%-25%). All patients with HCV transmission achieved sustained virologic response post full-course therapy (including one nonresponder from initial trial). A 1:1 matched analysis (N = 102) with contemporary HCV D-/R- transplants (controls) showed that although the pretransplant wait time was significantly shorter for D+/R- compared with D-/R- (mean: 1.8 vs. 4.4 years; p < .001), there were no differences in infections, rejection, development of de novo donor-specific antibody, or transplant outcomes up to 6 months of transplant.

Abstract
Introduction: Hepatitis C (HCV) is viral disease with a global impact. Over the last 10 years, the treatment of this disease has evolved. Treatment guidelines have evolved to adopt new medications for HCV. These drugs have shown efficacy over 90% throughout the class as well as a better safety profile than the previous recommended pharmacotherapy. Dual-therapy DAAs emerged with FDA approval of Ledipasvir/Sofosbuvir (LDV/SOF) in 2014.Areas Covered: LDV/SOF is a dual-therapy option for chronic HCV patients (>6 months of infection) in select genotypes. This article reviews the studies relevant to the pharmacokinetic/pharmacodynamic properties of these drugs as well as its trials leading to approval.Expert opinion: LDV/SOF is included in the AASLD/IDSA guidelines for the treatment of HCV genotypes 1a and 1b with or without cirrhosis and genotype 4 without cirrhosis with an evidence and recommendation rating of IA. Genotype 4 with cirrhosis and genotypes 5 and 6 carry a Class IIa level B recommendation. The combination is not FDA approved for genotypes 2 and 3. Single-pill regimens, like LDV/SOF, are important to maintain the quality of life of children and other special populations infected with HCV by shortening treatment regimens, avoiding complex pill regimens, and eliminating injection therapies.

Abstract
Introduction: The development of direct-acting antiviral (DAA) agents for the treatment of hepatitis C virus (HCV) infection has completely transformed the management of this disease. The advantages of using DAA therapies include high efficacy (sustained virological response (SVR) rate >95%) with minimal side effects, good tolerability, easy drug administration (once daily oral dosing), and short duration of treatment (8-12 weeks). This transformative nature of DAA therapy underpins the goal of the World Health Organization to eliminate HCV infection as a public health threat by 2030.Areas covered: This review seeks to address the current status of DAA therapies, including recent developments, current limitations, and future challenges.Expert opinion: The current DAA regimens, with their high effectiveness and safety profiles, have changed patient perception of HCV infection from a disease that requires complex evaluation and long-term monitoring to a disease that can be cured after one visit to the general practitioner. Despite the remarkably high success rate of DAAs, few patients (4-5%) fail to obtain SVR even after treatment. Five years ahead, the landscape of HCV treatment will undoubtedly continue to evolve, and more pan-genotypic treatment options will be available to all patients.

Abstract
BACKGROUND Hepatitis C virus (HCV) infected adolescents with beta-thalassemia major (BTM) are considered a potential population for HCV micro-elimination model development where BTM may negatively impact the pharmacokinetic exposure parameters of sofosbuvir/ledipasvir (SOF/LED). OBJECTIVES The study aimed at studying the effect of BTM on SOF/LED and SOF metabolite (GS-331007) pharmacokinetics. METHODS A prospective, controlled study recruiting BTM and control HCV infected adolescents (Clinicaltrials.gov identifier-NCT04353986). Pharmacokinetic exposure to GS-331007 and LED was the primary pharmacokinetic outcome. No-effect boundaries were set to 90% confidence interval (CI) of exposure geometric mean ratio (GMR) within 70-143%. Dose suitability was based on the 90% CI of exposure GMR within 50-200% compared to adults. The percentage of patients achieving sustained virologic response 12 weeks post-treatment (SVR12) was the primary efficacy endpoint. RESULTS Thirteen patients were enrolled per study group. All patients were included in the pharmacokinetic analysis (n=26). BTM patients showed lower GS-331007 and LED exposure that could, respectively, be as low as 45.4% and 36.1% compared to their control group. GS-331007 exposure in BTM patients was nearly half (56.8%, 90% CI 45.3-71.2%) that observed in adults. Despite that low drug exposure in 46.2% of BTM patients may alert dose unsuitability, they achieved SVR12. Moreover, patients with total bilirubin ≥1.93 mg/dL were predicted to have low GS-331007 exposure (0.913 receiver operating characteristic area under the curve with sensitivity and specificity >80%). CONCLUSION AND RELEVANCE The identified systematically lower drug exposure in BTM patients might partially explain relapses or treatment failures among BTM patients reported in other studies. BTM may be a hurdle towards implementing HCV micro-elimination model that may necessitate dose-adjustment.

Shortage of organs for liver transplantation (LT) and the availability of highly efficient pan-genotypic direct-acting antivirals (DAAs) against hepatitis C virus (HCV) have allowed the use of livers from HCV-positive antibody/negative nucleic acid test donors (dHCV Ab+/NAT-) into aviremic HCV recipients over the last few years. We report the case of a patient who received an LT from an HCV Ab+/NAT- donor and, after HCV viremic conversion, developed a nephrotic syndrome due to a focal proliferative glomerulonephritis early after LT. Patient's renal function and proteinuria resolved after successful treatment with DAAs. Renal and hepatic function remain normal over 24 months of follow-up. This case restates the success of LT using livers from dHCV Ab+/NAT- in aviremic recipients in the context of DAAs while illustrating the risk for potential complications associated with the HCV transmission and reinforcing the importance of early initiation of anti-HCV therapy.

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
Liver transplantation (LT) using allografts from hepatitis C virus (HCV)-viremic/nucleic acid testing-positive donors' (DNAT+) organs into HCV-aviremic recipients (rHCV-) has been limited owing to nearly universal HCV transmission and concerns regarding availability, safety, and efficacy post-LT with direct-acting antiviral (DAA) therapy. We report our experience of LT using DNAT+ organs into rHCV- as a routine standard of care. Following verification of DAA access, absence of critical drug-drug interactions (DDIs) with DAAs, and informed consent, allocated DNAT+ organs were offered to patients on the waiting list for LT irrespective of recipient HCV status. Between June 2018 and December 2019, 292/339 rHCV- received an LT. Forty-seven patients were excluded from analysis because of recipient HCV viremia, refusal to receive DNAT+ organs, or inability to receive DAA therapy post-LT. Of these 292 patients, 61 rHCV- received DNAT+ livers (study group), and 231 rHCV- received DNAT- (aviremic donors [nuclear acid test-negative donors]) livers (control group). Recipient and donor characteristics as well as 1-year post-LT patient and graft survival were similar between groups. In the study group, 4 patients died, and 1 patient required retransplantation within the first year post-LT (all unrelated to HCV); 56 patients received DAA therapy, with a median time from LT to the start of DAA treatment of 66.9 days (interquartile range [IQR], 36-68.5), and 51 patients completed DAA treatment, all achieving sustained virologic response for 12 or more weeks (SVR-12) (1 patient required retreatment owing to relapse following initial DAA therapy). No patients had evidence of fibrosing cholestatic hepatitis or extrahepatic manifestations of HCV. This report indicates that transplantation of DNAT+ livers into rHCV- and subsequent DAA therapy is associated with clinical outcomes comparable to those achieved with DNAT- allografts.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is still one of the leading causes of chronic liver disease, with chronically infected making up approximately 1% of the global population. Of those infected, 70% (55-85%) will develop chronic HCV infection. Chronic HCV infection causes substantial morbidity and mortality, with complications including cirrhosis, end-stage liver disease, hepatocellular carcinoma, and eventually death. OBJECTIVE Therapeutic options for chronic HCV infection have evolved dramatically since 2014, with a translation from pegylated interferon and ribavirin (associated with suboptimal cure and high treatment-related toxicity) to oral direct-acting antiviral treatment. There are four classes of direct-acting antivirals which differ by their mechanism of action and therapeutic target. They are all pointed to proteins that form the cytoplasmic viral replication complex. Multiple studies have demonstrated that direct-acting antiviral therapy is extremely well tolerated, highly efficacious, with few side effects. METHODS We performed an indexed MEDLINE search with keywords regarding specific direct-acting antiviral regimes and their pharmacokinetics, drug-drug interactions, and metabolism in specific settings of pregnancy, lactation, liver cirrhosis, liver transplantation and HCC risk, kidney failure and kidney transplantation. RESULTS We present a comprehensive overview of specific direct-acting antiviral metabolism and drug-drug interaction issues in different settings. CONCLUSION Despite its complex pharmacokinetics and the possibility of drug-drug interactions, direct-acting antivirals are highly efficacious in providing viral clearance, which is an obvious advantage compared to possible interactions or side effects. They should be administered cautiously in patients with other comorbidities, and with tight control of immunosuppressive therapy.

Abstract
Activation and viral control of the innate immune response are hallmarks of hepatitis C virus (HCV) infection and are major determinants of spontaneous clearance or progression to chronic infection and liver disease. In this review, we provide a contemporary overview of how HCV is sensed by the host cell to trigger innate immune activation and the mechanisms deployed by the virus to evade this response. Type I and III interferons (IFNs) are crucial mediators of antiviral innate immunity against HCV, and we specifically highlight the importance of IFN-λ host genetics for the outcome of HCV infection. Last, we focus on the proinflammatory responses elicited by HCV infection and describe our current understanding of how interleukin (IL)-1β signaling and cross talk between the IL-1β and IFN signaling pathways lead to sustained inflammation and increased risk of liver pathology.

Abstract
Despite considerable progress in the development of antiviral drugs, among which anti-immunodeficiency virus (HIV) and anti-hepatitis C virus (HCV) medications can be considered real success stories, many viral infections remain without an effective treatment. This not only applies to infectious outbreaks caused by zoonotic viruses that have recently spilled over into humans such as severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), but also ancient viral diseases that have been brought under control by vaccination such as variola (smallpox), poliomyelitis, measles, and rabies. A largely unsolved problem are endemic respiratory infections due to influenza, respiratory syncytial virus (RSV), and rhinoviruses, whose associated morbidity will likely worsen with increasing air pollution. Furthermore, climate changes will expose industrialized countries to a dangerous resurgence of viral hemorrhagic fevers, which might also become global infections. Herein, we summarize the recent progress that has been made in the search for new antivirals against these different threats that the world population will need to confront with increasing frequency in the next decade.

Abstract
Chronic hepatitis C (CHC) is a major cause of cirrhosis, hepatocellular carcinoma (HCC), and mortality. Eliminating hepatitis C virus (HCV) can greatly improve long-term outcomes. Several direct-acting antiviral agents (DAAs), including sofosbuvir (SOF) plus different NS5A inhibitors, as well as non-SOF-based DAAs, including glecaprevir/pibrentasvir (GLE/PIB), have been approved for treating CHC genotype-2 (GT-2) patients in Taiwan. However, there is limited real-world effectiveness data regarding these different regimens. Thus, we aimed to evaluate the real-world efficacy in CHC GT-2 patients who underwent these DAA regimens. We retrospectively enrolled CHC GT-2 patients who were treated with SOF-based DAAs or GLE/PIB at a single medical center. A total of 704 enrolled patients were treated with either SOF + ribavirin (RBV), SOF/daclatasvir (DCV) ± RBV, SOF/ledipasvir (LDV) ± RBV, SOF/velpatasvir (VEL) ± RBV, or with GLE/PIB. The overall sustained virological response (SVR) rate was 97.9%. The SVR rate was significantly lower in the SOF + RBV group (95.6%) than in the non-SOF + RBV (98.9%) group, especially compared to the SOF/DCV (100%) and GLE/PIB groups (99.5%). Among patients treated with SOF + RBV, cirrhotic patients had significantly lower SVR rates than noncirrhotic patients (89.4% vs 98.2%). Multivariate analysis showed that patients with a younger age, hepatitis B virus coinfection, baseline cirrhosis, or those who received SOF + RBV were less likely to achieve SVR. In conclusion, for CHC GT-2 patients, SOF in combination with DCV, LDV, or VEL, as well as GLE/PIB, achieved similar high efficacies, regardless of cirrhosis, treatment experience, or chronic kidney disease status. Therefore, the use of DAA therapy to eradicate HCV should not be delayed in these populations.

Abstract
BACKGROUND/AIM Chronic hepatitis-C infection is a great health burden in Egypt. The effect of anemia on the efficacy and safety of direct-acting anti-viral (DAA) therapies for those with chronic-kidney disease (CKD) has not been evaluated. PATIENTS/METHODS This single-center retrospective study included 235 renal patients: i.e., 70-CKD patients not on hemodialysis (42 with anemia, 28 without); 40 hemodialysis patients (16 anemic; 24 non-anemic), and 125 kidney-transplant (KTx) recipients (40 anemic; 85 non-anemic). Anemia was defined by a hemoglobin level < 10.5 g/dL. Hemodialysis patients received ritonavir-boosted paritaprevir/ombitasvir. KTx patients received sofosbuvir/daclatasvir. CKD patients with eGFR > 30 mL/min/1.73 m2 received sofosbuvir/daclatasvir. Those with eGFR < 30 mL/min/1.73 m2 received ritonavir-boosted paritaprevir/ombitasvir; 64 non-anemic patients also received ribavirin therapy. RESULTS Mean age of CKDs was 49.1 years, 43.2 years for HDs, and 45.2 years for KTx patients. Most were male; body-mass index was ~ 23.8. Anemia did not affect the efficacy of DAAs in hemodialysis, CKD, or KTx patients. Most patients achieved a rapid virologic response (RVR), and a 12- and 24-week sustained viral response. Worsening of anemia among the non-anemic group was mostly related to ribavirin therapy in hemodialysis patients (11/16 patients). Acute kidney injury in CKDs occurred more frequently within the anemic group (59.5%) compared to the non-anemic group (32.1%). For KTx, graft impairment was more common among the anemic group (7/40) compared to the non-anemic group (2/85). CONCLUSION Hemoglobin levels of < 10.5 g/dL prior to DAA treatment did not affect the virological response in renal patients but was associated with increased serum creatinine among KTx and those with CKD.

Abstract
Hepatitis C virus (HCV) infection is a major health problem all over the world including Egypt. Chronic HCV infection is usually accompanied by decrease of libido and erectile dysfunction. This study aimed to evaluate the efficacy of new oral direct acting antiviral (DAA) therapy on sexual function of male patients with HCV. This study was conducted on 200 male participants divided into two groups, first group included 100 male patients with HCV and the second group included 100 healthy age matched males as a control. Patients received DAA for three months and virological free status was confirmed by polymerase chain reaction. All participants were subjected to full history taking, general examination and local genital examination, assessment of sexual function by a validated Arabic version of the international index of erectile function-5. Laboratory investigations included liver functions serum testosterone, free testosterone, sex hormone-binding globulin and bioavailable testosterone. Results of this study showed that patients with HCV suffer from sexual dysfunction than controls that significantly improved after DAA therapy, and this is accompanied by increasing of bioavailable testosterone. It could be concluded that beside its effectiveness in treatment of HCV infection, DAA therapy can improve sexual function in male patients with HCV.

High viral load predicts virologic failure in chronic genotype 2 hepatitis C virus-infected patients receiving glecaprevir/pibrentasvir therapy. J Formos Med Assoc 2020; 119:1593-1600. [PMID: 32839045 DOI: 10.1016/j.jfma.2020.08.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 07/12/2020] [Accepted: 08/09/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND The real-world data of glecaprevir/pibrentasvir (GLE/PIB) therapy for patients with chronic hepatitis C virus (HCV) genotype 2 infection remained limited. We aimed to evaluate the possible predictors of virological failure and side effects of GLE/PIB therapy for chronic genotype 2 HCV-infected patients in a real-world setting. METHODS A total of 326 compensated HCV genotype 2 patients treated with GLE/PIB 12 weeks for cirrhotic patients (n = 56) and 8 weeks for non-cirrhotic patients (n = 270) were enrolled. RESULTS The sustained virological response 12 weeks off therapy (SVR12) was 98.1%, 100%, and 97.7% in overall, GLE/PIB 12-week, and 8-week group, respectively. There were 6 (1.8%) patients with early withdrawal, and 14.1% patients had pruritus, the major adverse effect. In multivariate analyses, end-stage renal disease (odds ratio (OR) = 4.056, 95% confidence interval (CI) = 1.477-11.14, p = 0.007) and hypertension (OR = 2.325, 95% CI = 1.171-4.616, p = 0.016) were two significant factors associated with pruritus. There were 6 patients with virologic failure. In patients receiving 8-week GLE/PIB therapy, the SVR12 rate was significant lower in high baseline viral load (≥107 IU/ml) group compared to low viral load group (90.6% v.s 98.7%, p = 0.025). Multivariate analyses showed that HCV RNA≥107 IU/ml was one of the independent factors (OR = 0.134, 95% CI = 0.024-0.748; p = 0.022) associated with SVR12. CONCLUSION GIE/PIB is an effective, tolerable and safe agent to treat genotype 2 HCV infected patients. However, high viral load (≥107 IU/ml) may predict virologic failure in non-cirrhotic patients receiving 8 weeks GIE/PIB treatment. This result should be further validated in a large cohort in the future.

Abstract
Hepatitis C virus (HCV) infection is a silent killer that leads to rapid progression of liver cirrhosis and hepatocellular carcinoma (HCC). High prevalence of HCV infection has been reported in Taiwan, especially in high-risk populations including people who inject drugs (PWID) and patients requiring dialysis. Besides, certain populations merit special considerations due to suboptimal outcome, potential drug-drug interaction, or possible side effect. Therefore, in the second part of this 2-part consensus, the Taiwan Association for the Study of the Liver (TASL) proposes the treatment recommendations for the special population in order to serve as guidance to optimizing the outcome in the direct-acting antiviral (DAA) era. Special populations include patients with acute or recent HCV infection, previous DAA failure, chronic kidney disease, decompensated cirrhosis, HCC, liver and other solid organ transplantations, receiving an HCV viremic organ, hepatitis B virus (HBV) and HCV dual infection, HCV and human immunodeficiency virus (HIV) coinfection, active tuberculosis infection, PWID, bleeding disorders and hemoglobinopathies, children and adolescents, and pregnancy. Moreover, future perspectives regarding the management of hepatitis C are also discussed and summarized in this consensus statement.

Abstract
The hepatitis C virus mainly infects the liver but is also able to infect and replicate in other body compartments by creating an extra-hepatic reservoir that may influence the persistence of the infection after transplantation. It is unknown whether antiviral drugs affect the viral extra-hepatic sites. We evaluated the ability of pegylated/interferon + ribavirin and sofosbuvir + ribavirin to clear the virus from the gastrointestinal mucosa of liver-transplanted patients with HCV recurrence after transplantation. A total of 51 liver-transplanted patients, 30 treated with pegylated/interferon + ribavirin (ERA1) and 21 treated with sofosbuvir + ribavirin (ERA2), were enrolled, and blood serum and gastrointestinal tissues analyzed for the presence of HCV-RNA. In the ERA1 group, the 46.6% of patients had a sustained viral response to antiviral treatment, and gastrointestinal biopsies were positive for HCV in 73.3% of cases, 54.5% of responders, and 45.5% of non-responders. In the ERA2 group, the 66.6% had a sustained viral response, and gastrointestinal HCV-RNA was present in the 14.3% of patients, all relapsers. Sofosbuvir + ribavirin cleared the intestinal HCV in 85.7% of patients with recurrent HCV infection, while pegylated/interferon + ribavirin cleared it in 26.6% of treated patients, demonstrating the better effectiveness of new direct antiviral agents in clearing HCV intestinal reservoir.

Abstract
Although the direct-acting antivirals revolutionized the hepatitis C virus (HCV) infection treatment in the last decade, more efforts are needed to reach the elimination of HCV in the absence of a vaccine. 4-(Piperazin-1-yl)-2-((p-tolylamino)methyl)-benzonitrile (1) is a modest HCV inhibitor identified from an in-house screening using a HCV-infected Huh7.5 cell culture. Starting from it, the chemical optimization afforded a new 2-((4-arylpiperazin-1-yl)methyl)benzonitrile scaffold with significantly increased antiviral activity against HCV. A highly effective HCV inhibitor, 35 (L0909, EC50 = 0.022 μM, SI > 600), was identified by the structure-activity relationship study. The biological study revealed that L0909 could block HCV replication by acting on the HCV entry stage. The high sensitivity to clinical resistant HCV mutants and synergistic effect with clinical drugs were observed for this compound. The further pharmaceutical studies demonstrated that L0909 is long-lasting, is orally available, and has low toxicity in vivo. These results show L0909 as a promising HCV entry inhibitor for single or combinational therapeutic potential.

Abstract
As the first line of treatment for hepatitis C virus (HCV) infection, direct-acting antivirals (DAAs) have greater efficacy and fewer adverse effects than other treatments; however, drug-drug interactions (DDIs) must be avoided when used in combination with other medications, such as statins. HCV patients are mostly in the need for polypharmacy, particularly the comedication of DAAs and cardiovascular drugs such as statins. This poses a risk of pharmacokinetic interactions between the two classes of drugs that may lead to severe myopathy or even rhabdomyolysis. Therefore, evaluating the severity of the DDIs and managing them is important. A multidisciplinary team-based model of care for HCV patients receiving DAAs can review the pharmacology profiles of other drugs for relevant DDIs with the DAAs, before prescription. Such a model can also follow the patients through the therapeutic cycle to make sure that their medical regimen is safe and effective. This article reviews the comedication rate and DDI-prevalence in HCV patients receiving statins along with the DAAs, details the mechanisms involved, gives recommendations for management, and shares our experience with a multidisciplinary team-based care program for the treatment of HCV patients.

Abstract
Background and Aims: Liver biopsy remains the gold standard for staging of chronic liver disease following orthotopic liver transplantation. Noninvasive assessment of fibrosis with Fibro-test (FT) is well-studied in immunocompetent populations with chronic hepatitis C virus infection. The aim of this study is to investigate the diagnostic value of FT in the assessment of hepatic fibrosis in the allografts of liver transplant recipients with evidence of recurrent hepatitis C. Methods: We retrospectively compared liver biopsies and FT performed within a median of 1 month of each other in orthotopic liver transplantation recipients with recurrent hepatitis C. Results: The study population comprised 22 patients, most of them male (19/22), and with median age of 62 years. For all patients, there was at least a one-stage difference in fibrosis as assessed by liver biopsy compared to FT, while for the majority (16/22) there was at least a two-stage difference. The absence of correlation between the two modalities was statistically demonstrated (Mann-Whitney U test, p = 0.01). In detecting significant fibrosis (a METAVIR stage of F2 and above), an FT cut-off of 0.5 showed moderate sensitivity (77%) and negative predictive value (80%), but suboptimal specificity (61%) and positive predictive value (58%). Conclusions: In post-transplant patients with recurrent hepatitis C, FT appears to be inaccurately assessing the degree of allograft fibrosis, therefore limiting its reliability as a staging tool.

Abstract
We conducted an adaptive design single-center pilot trial between October 2017 and November 2018 to determine the safety and efficacy of ultra-short-term perioperative pangenotypic direct acting antiviral (DAA) prophylaxis for deceased hepatitis C virus (HCV)-nucleic acid test (NAT) positive donors to HCV negative kidney recipients (D+/R-). In Group 1, 10 patients received one dose of SOF/VEL (sofusbuvir/velpatasvir) pretransplant and one dose on posttransplant Day 1. In Group 2A (N = 15) and the posttrial validation (Group 2B; N = 25) phase, patients received two additional SOF/VEL doses (total 4) on Days 2 and 3 posttransplant. Development of posttransplant HCV transmission triggered 12-week DAA therapy. For available donor samples (N = 27), median donor viral load was 1.37E + 06 IU/mL (genotype [GT]1a: 70%; GT2: 7%; GT3: 23%). Overall viral transmission rate was 12% (6/50; Group 1:30% [3/10]; Group 2A:13% [2/15]; Group 2B:4% [1/25]). For the 6 viremic patients, 5 (83%) achieved sustained virologic response (3 with first-line DAA therapy; and two after retreatment with second-line DAA). At a median follow-up of 8 months posttransplant, overall patient and allograft survivals were 98%, respectively. The 4-day strategy reduced viral transmission to 7.5% (3/40; 95% confidence interval [CI]: 1.8%-20.5%) and could result in avoidance of prolonged posttransplant DAA therapy for most D+/R - transplants.

Abstract
The introduction of highly efficient therapies with direct-acting antivirals (DAA) for patients with chronic hepatitis C virus (HCV) infection offers exceptional opportunities to globally control this deadly disease. For achieving this ambitious goal, it is essential to prevent antiviral resistance against the most optimal first-line and retreatment DAA choices. We performed independent comparisons of the efficacy and barrier to resistance of pangenotypic DAA regimens for HCV genotype 2 infections, using previously and newly developed efficient cell culture-adapted strains of subtypes 2a, 2b, and 2c. With the applied experimental cell culture conditions, combination treatment with the sofosbuvir-velpatasvir or glecaprevir-pibrentasvir DAA regimen was efficient in eradicating HCV infections; in contrast, single-drug treatments frequently led to viral escape. Sequence analysis of drug targets from recovered viruses revealed known resistance-associated substitutions (RAS) emerging in the NS3 protease or NS5A after treatment failure. These RAS were genetically stable after viral passage, and viruses with these RAS exhibited significant phenotypic resistance. After sofosbuvir treatment failure, only a genotype 2a virus harbored NS5B RAS S282T and thus had decreased susceptibility to nucleotide analogs (nucs). However, in most cases, viral escape from sofosbuvir led to other NS5B substitutions but drug susceptibility was maintained, and in one case, no changes in NS5B were detected. For a genotype 2b virus, after treatment failure with sofosbuvir-velpatasvir, the efficacy of retreatment with glecaprevir-pibrentasvir was maintained due to the high barrier to resistance and low cross-resistance of pibrentasvir. Our findings suggest the slight superiority of glecaprevir-pibrentasvir against genotype 2b in culture, which could have potential therapeutic interest meriting more definitive investigations in the clinic.

Abstract
Introduction: Hepatitis C virus (HCV) is estimated to infect approximately 70 million people worldwide. If left untreated, chronic infection can progress to cirrhosis, liver failure or hepatocellular carcinoma. The advent of new direct-acting antivirals (DAA) has revolutionized patients' chances of treatment and viral elimination. Currently, several DAA options are available on the market.Areas covered: This review focuses on the pharmacokinetics, efficacy, tolerability and safety profile of DCV-TRIO, a twice-daily fixed-dose combination of daclatasvir, asunaprevir and beclabuvir approved in Japan for the treatment of genotype 1 HCV infection.Expert opinion: The DCV-TRIO combination achieved good response rates in genotype 1 patients (SVR12 ≥ 95% in naïve subtype 1b), independently from IL28B genotype, cirrhotic status and prior interferon exposure. On the other hand, unsatisfying response rates were reported in DAA-experienced patients and the risk of RAS selection should not be underestimated. Moreover, DCV-TRIO lacks differentiation from its earlier-launched DAA rivals, presents an inconvenient twice-daily dosing schedule and is not recommended in patients with advanced liver and kidney disease. All these drawbacks considerably limit its effective commercial potential. However, it can be a therapeutic option against HCV in tailored approaches according to the needs of different markets across the world.Abbreviations AE: adverse event; ALT: alanine aminotransferase; AST: aspartate aminotransferase; ASV: asunaprevir; AUC: area under the curve; BCRP: Breast Cancer Resistance Protein; BCV: boceprevir; BID: bis in die; CI: confidence intervals; CLcr: creatinine clearance; DAA: direct acting antivirals; DCV: daclatasvir; EC50: Half maximal effective concentration; GT: genotype; HCV: Hepatitis C virus; IFN: Interferon; NHL: non-Hodgkin lymphoma; OATP: Organic anion transporting polypeptides; OR: odds ratio; P-gp: P-glycoprotein; PK: pharmacokinetics; QD: quo die; RAS: resistance-associated substitutions; SVR: sustained virological response; USD: Unites States dollar.

Abstract
The hepatitis C virus (HCV) prevalence is extremely high in patients who consume and inject illicit drugs. Concerns about poor adherence and fear of interaction with drugs of abuse could constitute further disincentive for treatment initiation in these patients. We discussed the pharmacokinetics (PKs) and pharmacodynamics (PD) of currently prescribed direct antiviral agents (NSA5 inhibitors: daclatasvir, elbasvir, ledipasvir, pibrentasvir, velpatasvir; NS5B inhibitor: sofosbuvir; NS3/4A protease inhibitors: glecaprevir, grazoprevir, voxilaprevir) and most common substances of abuse (opioids: buprenorphine, fentanyl, heroin, methadone, morphine, oxycodone; stimulants: amphetamines, cathinones, cocaine; cannabinoids; ethanol). Overall, most direct-acting antivirals (DAAs) are substrates and inhibitors of the transmembrane transporter P-glycoprotein (P-gp), and several of them are metabolized by cytochrome P450 enzymes. Clinically relevant interactions are associated with P-gp and CYP3A modulators. Most substances of abuse are eliminated by Phase I and Phase II metabolizing enzymes, but none of them are either major inhibitors or inducers. PK studies did not show any relevant interactions between DAA and methadone or buprenorphine. Based on pharmacological considerations, neither efficacy loss nor adverse drug event associated with detrimental interaction are expected with opioids, stimulants, cannabinoids and ethanol. In summary, our literature review shows that the interaction potential of DAA with most opioids and illicit drugs is limited and should not be a hurdle to the initiate DAA.

Abstract
Tuberculosis (TB) and hepatitis C virus (HCV) infection are both major public health problems. Despite high rates of co-infection there is scarce literature addressing the convergence of the two diseases. One particularly unexplored area is the potential for simultaneous treatment of TB and HCV which would allow for leveraging an extensive global TB treatment infrastructure to help scale up HCV treatment. We review the drug metabolism of anti-TB and HCV drugs and the known and potential drug-drug interactions between recommended HCV regimens and individual anti-TB drugs. Rifampin is the only anti-TB drug to have been formally studied for potential drug interactions with anti-HCV direct-acting antivirals (DAAs) and existing data precludes these combinations. However, based on known pathways of drug metabolism and enzyme effects, the combination of HCV DAA regimens with all other anti-TB drugs may be feasible. Pharmacokinetic studies are needed next to help move co treatment regimens forward for clinical use among patients coinfected with TB and HCV.
