Comparison of the Efficacies of Direct-Acting Antiviral Treatment for HCV Infection in People Who Inject Drugs and Non-Drug Users. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58030436. [PMID: 35334612 PMCID: PMC8950806 DOI: 10.3390/medicina58030436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 03/10/2022] [Accepted: 03/14/2022] [Indexed: 11/16/2022]
Abstract
Background and Objectives: Hepatitis C virus (HCV) is a major cause of liver disease worldwide. People who inject drugs (PWIDs) constitute the majority of patients with HCV infection in the United States and Central Asia. There are several obstacles to treating HCV infection in PWIDs because PWIDs are often accompanied by concurrent infection, low compliance, substance abuse, and risky behavior. The aim of the study is to compare the efficacies of direct-acting antiviral (DAA) therapy for HCV infection in PWIDs and those without opioid injection. Materials and Methods: In this retrospective cohort study, we included 53 PWIDs with HCV infections treated on site in a methadone program and 106 age- and sex-matched patients with HCV infections who had no history of opioid injection (ratio of 1:2). All eligible subjects received anti-HCV treatment by DAA agents in our hospital from March 2018 to December 2020. The charts of these patients were carefully reviewed for demographic data, types of DAA agents, and treatment outcomes. The primary outcome measure was sustained virological response (SVR). Results: PWIDs and non-drug users had different HCV genotype profiles (p = 0.013). The former had higher proportions of genotype 3 (18.9% vs. 7.5%) and genotype 6 (24.5% vs. 14.2%) than the latter. The two patient groups had comparable rates of complete drug refilling (100.0% vs. 91.1%) and frequency of loss to follow-up (3.8% vs. 0.9%). However, PWIDs had a lower SVR rate of DAA treatment than non-drug users (92.2% vs. 99.0%; p = 0.04). Further analysis showed that both human immunodeficiency virus (HIV) coinfection and history of PWID were risk factors associated with treatment failure. The subjects with coinfection with HIV had lower SVR rates than those without HIV infection (50.0% vs. 96.5%; p = 0.021). Conclusions: PWIDs with HCV infections have higher proportions of HCV genotype 3 and genotype 6 than non-drug users with infections. DAA therapy can achieve a high cure rate (>90%) for HCV infection in PWID, but its efficacy in PWID is lower than that in non-drug users.

Novel pyridinium-type fullerene derivatives as multitargeting inhibitors of HIV-1 reverse transcriptase, HIV-1 protease, and HCV NS5B polymerase. Bioorg Med Chem Lett 2021; 49:128267. [PMID: 34271071 DOI: 10.1016/j.bmcl.2021.128267] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 07/05/2021] [Accepted: 07/11/2021] [Indexed: 11/26/2022]
Abstract
In the present study, we newly synthesized four types of novel fullerene derivatives: pyridinium/ethyl ester-type derivatives 3b-3l, pyridinium/carboxylic acid-type derivatives 4a, 4e, 4f, pyridinium/amide-type derivative 5a, and pyridinium/2-morpholinone-type derivative 6a. Among the assessed compounds, cis-3c, cis-3d, trans-3e, trans-3h, cis-3l, cis-4e, cis-4f, trans-4f, and cis-5a were found to inhibit HIV-1 reverse transcriptase (HIV-RT), HIV-1 protease (HIV-PR), and HCV NS5B polymerase (HCV NS5B), with IC50 values observed in the micromolar range. Cellular uptake of pyridinium/ethyl ester-type derivatives was higher than that of corresponding pyridinium/carboxylic acid-type derivatives and pyridinium/amide-type derivatives. This result might indicate that pyridinium/ethyl ester-type derivatives are expected to be lead compounds for multitargeting drugs to treat HIV/HCV coinfection.

Abstract
Hepatitis C is a major health problem worldwide, frequently resulting in cirrhosis and increasing the risk of hepatocellular carcinoma significantly. In recent years, the advent of direct-acting antivirals (DAAs) has dramatically improved the therapeutic outcomes in hepatitis C patients. In the last two years, several new DAA combinations have been approved for the treatment of the hepatitis C virus (HCV) infection, including elbasvir/grazoprevir, sofosbuvir/velpatasvir, sofosbuvir/velpatasvir/voxilaprevir, and glecaprevir/pibrentasvir. The newly approved DAA regimens may be prescribed with other drugs simultaneously, increasing the potential of pharmacokinetic interactions. Therefore, the knowledge and management of drug-drug interactions (DDIs) with DAAs should be considered a key issue in HCV therapy. This review summarizes researches of DDIs focusing on newly approved DAAs (elbasvir, grazoprevir, velpatasvir, voxilaprevir, glecaprevir, pibrentasvir) for patients undergoing HCV treatment to provide clinical consideration for comedication. With respect to DDIs, newly approved DAA regimens, including elbasvir/grazoprevir, sofosbuvir/velpatasvir, sofosbuvir/velpatasvir/voxilaprevir, and glecaprevir/pibrentasvir, are safely applicable.

Abstract
INTRODUCTION liver laboratory tests improve in hepatitis C virus (HCV)-monoinfected and cirrhotic patients who achieve HCV cure after interferon-free treatment. OBJECTIVE AND METHODS this study evaluates the changes in those tests in human immunodeficiency virus (HIV)-positive subjects with an eradicated HCV-coinfection using direct-acting antivirals and with a pre-therapy liver stiffness ≥ 14.6 kPa or clinical data of cirrhosis. Serum albumin, bilirubin, creatinine, platelet count and international normalized ratio (INR) values were collected at baseline, week 4, at the end of treatment and 24 weeks after the end-of-treatment. Fibrosis-4 score (FIB4) and Model for End-stage Liver Disease (MELD) score values were calculated and liver stiffness was estimated by transient elastography at baseline and 24 weeks after the end-of-treatment. The means were compared with the Student's t test or the repeated measures ANOVA test. RESULTS direct-acting antivirals were prescribed to 131 HIV/HCV-coinfected cirrhotic patients. A sustained virological response was confirmed in 120 cases. Albumin, bilirubin and platelet count values improved in the entire population 24 weeks after the end-of-treatment. INR and MELD score values decreased when patients with atazanavir and/or acenocoumarol were excluded and liver fibrosis tests significantly diminished. Nine patients developed liver decompensation and there were three deaths. CONCLUSION in conclusion, HCV eradication was associated with a short-term improvement in biochemical liver function and fibrosis tests in HIV-coinfected patients with cirrhosis, although clinical events still occur.

Abstract
Background Combating infectious diseases caused by influenza virus is a major challenge due to its resistance to available drugs and vaccines, side effects, and cost of treatment. Nanomedicines are being developed to allow targeted delivery of drugs to attack specific cells or viruses. Materials and Methods In this study, mesoporous silica nanoparticles (MSNs) functionalized with amino groups and loaded with natural prodrugs of shikimic acid (SH), quercetin (QR) or both were explored as a novel antiviral nanoformulations targeting the highly pathogenic avian influenza H5N1 virus. Also, the immunomodulatory effects were investigated in vitro tests and anti-inflammatory activity was determined in vivo using the acute carrageenan-induced paw edema rat model. Results Prodrugs alone or the MSNs displayed weaker antiviral effects as evidenced by virus titers and plaque formation compared to nanoformulations. The MSNs-NH2-SH and MSNs-NH2-SH-QR2 nanoformulations displayed a strong virucidal by inactivating the H5N1 virus. They induced also strong immunomodulatory effects: they inhibited cytokines (TNF-α, IL-1β) and nitric oxide production by approximately 50% for MSNs-NH2-SH-QR2 (containing both SH and QR). Remarkable anti-inflammatory effects were observed during in vivo tests in an acute carrageenan-induced rat model. Conclusion Our preliminary findings show the potential of nanotechnology for the application of natural prodrug substances to produce a novel safe, effective, and affordable antiviral drug.

Abstract
Direct-acting antivirals (DAAs) are known victims (substrate) and perpetrators (cause) of drug–drug interactions (DDIs). These DAAs are used for the treatment of hepatitis C virus (HCV) infections and are highly effective drugs. Drugs used for cardiovascular risk management are frequently used by HCV-infected patients, whom also are treated with DAAs. Therefore, the aim of this review was to describe DDIs between cardiovascular drugs (CVDs) and DAAs. An extensive literature search was performed containing search terms for the marketed DAAs and CVDs (β-blocking agents, ACE inhibitors, angiotensin II antagonists, renin inhibitors, diuretics, calcium channel blockers, statins/ezetimibe, fibrates, platelet aggregation inhibitors, vitamin K antagonists, heparins, direct Xa inhibitors, nitrates, amiodarone, and digoxin). In particular, the drug labels from the European Medicines Agency and the US Food and Drug Administration were used. A main finding of this review is that CVDs are mostly victims of DDIs with DAAs. Therefore, when possible, monitoring of pharmacodynamics is recommended when coadministering these drugs with DAAs. Nevertheless, it is sometimes better to discontinue a drug on a temporary basis (statins, ezetimide). The DAAs are victims of DDIs in combination with bisoprolol, carvedilol, labetalol, verapamil, and gemfibrozil. Despite there are many DDIs predicted in this review, most of these DDIs can be managed by monitoring the efficacy and toxicity of the victim drug or by switching to another CVD/DAA.

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
The advent of direct-acting antiviral agents (DAAs) has transformed the hepatitis C virus (HCV) therapeutic landscape in terms of efficacy and safety, with a cure rate of more than 90%. However, an important potential for drug-drug interactions (DDIs) is expected with these combinations, particularly in patients with other comorbidities (e.g. HIV co-infection, cardiovascular diseases). Each DAA can be a substrate, an inhibitor and/or an inducer of metabolic enzymes and drug efflux transporters. DAAs can act as both victims and perpetrators of DDIs and can sometimes increase the risk and/or intensity of side effects or limit the efficacy of treatment. Therefore, knowledge and management of DDIs with DAAs should be considered a key issue of HCV therapy. This review describes the pharmacokinetic profile of currently used and recommended DAA regimens and summarizes available data regarding DDIs to optimize HCV treatment in clinical practice.

Abstract
OBJECTIVE No brand direct-acting antiviral agents (DAAs) are available for treatment of HIV-1/HCV co-infected patients in China. This study aimed to observe the therapeutic efficacy and safety of generic DAAs for affected Chinese patients. DESIGN Real-world setting to elucidate whether DAAs were tolerated and effective in HIV-1/HCV co-infected patients. METHODS 176 HIV-1/HCV co-infected patients received anti-HCV DAA treatment together with ART regimens for HIV infection. Among the 176 patients, 99 patients were treated with SOF + DCV ± RBV, 60 patients were treated with SOF + LDV ± RBV, and 17 patients received SOF + RBV ± Peg-IFN regimens, for 12 or 24 weeks, respectively. The primary endpoint was undetectable HCV RNA 12 weeks after therapy was completed (SVR12). Data pertaining to safety and adverse events were analyzed. RESULTS 151/176 HIV-1/HCV co-infected patients finished the treatment and 12-week follow-up. SVR12 for the patients treated with regimens of SOF + DCV, SOF + DCV+RBV, SOF + Peg-IFN+RBV, SOF + RBV, SOF + LDV, and SOF + LDV+RBV for 12 or 24 weeks was 100% (75/75), 100% (11/11), 100% (14/14), 100% (2/2), 95.2% (40/42), and 100% (7/7), respectively. HIV-1/HCV co-infected patients with liver cirrhosis achieved well SRV12. Notably, there was no significant difference in adverse effects among patients with different baseline CD4+ T-cell count in those who received DAA regimens with or without Peg-IFN and RBV. CONCLUSION We showed generic SOF + DCV and SOF + LDV regimens were well tolerated and with high efficiency. Patient's baseline CD4+ T-cell count did not exhibit significant difference in adverse effects.

Glomerular filtration rate change during chronic hepatitis C treatment with Sofosbuvir/Ledipasvir in HCV/HIV Coinfected patients treated with Tenofovir and a boosted protease inhibitor: an observational prospective study. BMC Infect Dis 2018; 18:364.

Abstract
INTRODUCTION Concomitant use of ledipasvir and boosted protease inhibitors (PIs) may increase the risk of tenofovir (TDF) nephrotoxicity, since both these drugs increase TDF levels. Our aim was to evaluate glomerular filtration rate (eGFR) evolution during HCV treatment with sofosbuvir/ledipasvir (SOF/LDV) in HCV/HIV coinfected patients, according to their antiretroviral treatment (ARV). METHODS Observational prospective study of HCV/HIV coinfected patients treated with SOF/LDV. eGFR evolution was evaluated during and 12 weeks after HCV treatment. Patients were categorized in three groups based on ARV regimen: non TDF, non-boosted TDF and TDF + boosted PI. RESULTS We included 273 patients: 145 were receiving a non-TDF regimen, 78 a non-boosted TDF scheme and 50 were receiving TDF + boosted PI. We observed a statistically significant decrease in eGFR during treatment in all groups (non TDF p = 0.03, 95%CI [0.23-3.86], non-boosted TDF p < 0.01, 95%CI [3.36-7.44], TDF + PI p = 0.01, 95%CI [1.09-7.53]). The decrease was more pronounced in those receiving unboosted TDF (- 5.40 ml/min/1.73m2), but differences in eGFR decrease between the three groups were small and not statistically different (p = 0.06). eGFR decrease was greater in patients treated for 24 weeks (p = 0.009) and in cirrhotic patients (p = 0.036). At the end of follow up a recovery of eGFR was observed in all groups. CONCLUSION We observed a significant decrease in eGFR during treatment in all study groups, that was small and reversible after SOF/LDV discontinuation. TDF was not associated with an increase in renal toxicity.

Abstract
Background Possible drug-drug interactions (DDIs) between antiretrovirals (ARVs) and direct-acting antiviral agents (DAAs) are of some concern. Objectives To investigate ARV plasma trough concentrations (Ctrough) before and during DAAs in patients treated in the real world. Methods Single-centre, prospective, observational study including HIV/HCV coinfected persons undergoing DAA treatment. Self-reported adherence was assessed and ARVs Ctrough measured by HPLC-UV. Blood samples were collected before and after 2 months of DAA treatment. Results One-hundred and thirty-seven patients were included: 21.2% treated with ombitasvir/paritaprevir/ritonavir ± dasabuvir (2D/3D) and 78.8% with sofosbuvir-based regimens. Suboptimal Ctrough before and during DAA was found, respectively, in 3 (10.3%) and 3 (10.3%) cases treated with 2D/3D, and 16 (14.8%) and 11 (10.2%) with sofosbuvir-based regimens, even if self-reported ARV adherence was always ≥93%. In 2D/3D-treated patients, median darunavir Ctrough during DAAs was significantly lower than observed before DAAs [1125 ng/mL (IQR, 810-1616) versus 1903 ng/mL (IQR 1387-3983), respectively] (n = 5; P = 0.009), with a 40.9% decrease. In the same group, no differences in atazanavir or raltegravir concentrations were found. In patients treated with sofosbuvir-based regimens, Ctrough of all ARVs were similar before and during DAAs. Conclusions In the real world of HIV/HCV coinfected patients, ARV plasma concentrations during DAAs were generally not different from those found before anti-HCV treatment. Although assessed in a small number of patients, darunavir concentrations during 2D/3D showed a significant reduction when compared with those found before DAAs. ARV plasma concentrations measurement during anti-HCV treatment may give useful information for managing HIV/HCV coinfected persons receiving treatment for both infections.

Adverse drug reactions during hepatitis C treatment with direct-acting antivirals: The role of medication errors, their impact on treatment discontinuation and their preventability. New insights from the Campania Region (Italy) spontaneous reporting system. J Clin Pharm Ther 2018; 43:867-876. [PMID: 30014479 DOI: 10.1111/jcpt.12744] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Accepted: 06/22/2018] [Indexed: 12/14/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE Medication errors, such as unnecessary treatment discontinuation during treatment with direct-acting antivirals (DAAs), can lead to imbalances in the benefit-to-risk ratio. This risk is especially high when the medication error leads to adverse drug reactions (ADRs). However, to date, evidence on the frequency of this phenomenon is scarce. This study aims to provide better insight into ADRs possibly due to medication errors leading to DAA discontinuation and their preventability. METHODS The Italian Pharmacovigilance Network database was used to extract individual case safety reports (ICSRs) generated from July 2012 to March 2017 via the Campania Region (Italy) spontaneous reporting system. ICSRs that included ledipasvir/sofosbuvir, ombitasvir/paritaprevir/ritonavir, dasabuvir, daclatasvir, sofosbuvir, simeprevir or elbasvir/grazoprevir as suspected drugs were included in this study. A preventability assessment was then performed utilizing the "P-Method," an algorithm that evaluates known risk factors due to medication errors that can be detected in ICSRs. RESULTS AND DISCUSSION Of the 355 cases included in this study, 6 (1.69%) were classified as preventable and 52 (14.6%) were classified as potentially preventable. The most frequently identified critical criteria (risk factor) for preventable or potentially preventable cases were drug-drug interactions and incorrect drug dosing as part of the antiviral treatment scheme. In total, 89 of the 355 cases (25.1%) discontinued use of the DAAs due to ADRs, of which 20 of the 89 cases (22.5%) were due to an unimportant medical event as classified by the European Medicine Agency important medical event list. WHAT IS NEW AND CONCLUSION This study found a proportion of preventable/potentially preventable ADRs involving DAA, which could be improved in the Campania Region (Italy). Additionally, the study identified a high proportion of seemingly unnecessary DAA discontinuations among patients who experienced ADRs.

Abstract
Objectives The aim of this multicenter retrospective study was to investigate safety and efficacy of direct acting antiviral (DAA) treatment in the rare subgroup of patients with HCV/HIV-coinfection and advanced liver cirrhosis on the liver transplant waiting list or after liver transplantation, respectively. Methods When contacting 54 German liver centers (including all 23 German liver transplant centers), 12 HCV/HIV-coinfected patients on antiretroviral combination therapy were reported having received additional DAA therapy while being on the waiting list for liver transplantation (patient characteristics: Child-Pugh A (n = 6), B (n = 5), C (n = 1); MELD range 7–21; HCC (n = 2); HCV genotype 1a (n = 8), 1b (n = 2), 4 (n = 2)). Furthermore, 2 HCV/HIV-coinfected patients were denoted having received DAA therapy after liver transplantation (characteristics: HCV genotype 1a (n = 1), 4 (n = 1)). Results Applied DAA regimens were SOF/DAC (n = 7), SOF/LDV/RBV (n = 3), SOF/RBV (n = 3), PTV/r/OBV/DSV (n = 1), or PTV/r/OBV/DSV/RBV (n = 1), respectively. All patients achieved SVR 12, in the end. In one patient, HCV relapse occurred after 24 weeks of SOF/DAC therapy; subsequent treatment with 12 weeks PTV/r/OBV/DSV achieved SVR 12. One patient underwent liver transplantation while on DAA treatment. Analysis of liver function revealed either stable parameters or even significant improvement during DAA therapy and in follow-up. MELD scores were found to improve in 9/13 therapies in patients on the waiting list for liver transplantation; in only 2 patients a moderate increase of MELD scores persisted at the end of follow-up. Conclusion DAA treatment was safe and highly effective in this nation-wide cohort of patients with HCV/HIV-coinfection awaiting liver transplantation or being transplanted.

Hepatology 2018; 67:847-857. [PMID: 29108121 DOI: 10.1002/hep.29642] [Citation(s) in RCA: 48] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2017] [Revised: 09/26/2017] [Accepted: 11/02/2017] [Indexed: 12/11/2022]
Abstract
UNLABELLED The treatment of chronic hepatitis C (HCV) in human immunodeficiency virus 1 (HIV)-infected individuals has been historically marked by low sustained virologic response (SVR) rates in comparison to those without HIV infection, resulting in the Food and Drug Administration labeling those coinfected as a "special population with an unmet medical need." We systematically reviewed the treatment of chronic HCV infection in those infected with HIV. We propose that with the advent of direct-acting antiviral (DAA) agents, patients coinfected with HCV and HIV have similar SVR rates as HCV-monoinfected persons and that DAAs address an unmet medical need in this population. A review was performed using Medical Subject Heading terms within the PubMed, EMBASE, and Cochrane Library databases to search for studies dated between January 2004 and July 2017. Keywords used in the study included "hepatitis C," "HIV," "coinfection," and "direct-acting antiviral." SVR rates for those with HCV and HIV coinfection treated with interferon-based therapies were substantially lower that SVR rates of HCV-monoinfected individuals. The advent of DAA agents has resulted in similar SVR rates between monoinfected and coinfected individuals, with SVR >93%. These medications have been demonstrated to have improved safety, efficacy, and tolerability in comparison to interferon-based regimens. CONCLUSION The designation of a "special population" for those with coinfection requires reconsideration; DAA therapies have resulted in similarly high rates of SVR for HCV infection in those with and without HIV infection; despite these improvements, however, clinicians must be cognizant of negative predictors of SVR and barriers to treatment that may be more common in the coinfected population.

Abstract
Background Data on the efficacy, safety, and concomitant use with other drugs of the combination ritonavir-boosted paritaprevir/ombitasvir plus dasabuvir (PrOD) in HIV/HCV-coinfected patients in real life are limited. The objectives of this study were to analyze these topics in HIV/HCV-coinfected subjects bearing HCV genotype 1 (GT1). Methods One hundred and eighty-two HIV/HCV-coinfected patients with GT1 (87 1a, 71 1b, 23 other) treated with PrOD, plus ribavirin (RBV) in 119 cases, in routine clinical practice were analyzed. The main variable of efficacy was sustained virological response (SVR) 12 weeks after completing therapy in an intention-to-treat (ITT) analysis and that of safety treatment discontinuation because of adverse effects. Factors associated with SVR were analyzed with a modified ITT (mITT) strategy. Results One hundred and seventy-two (94%) patients attained SVR, 3 (2%) experienced a relapse and two (1%) discontinued therapy due to adverse events. The rates of SVR in subjects with GT 1a and 1b by mITT were, respectively, 97% and 98%. Sixty-five (98%) out of 66 patients with cirrhosis and 107 (98%) out of 110 (p = 1) non-cirrhotics achieved SVR. Fifty-five (95%) patients on concomitant darunavir therapy developed SVR vs. 117 (99%) (p = 0.105) of those without DRV. RBV dose was reduced in 13 (11%) patients and permanently discontinued in 2 (2%), with no impact on SVR. Conclusions PrOD is highly effective and well tolerated in HIV/HCV-coinfected patients with GT1 in routine clinical practice. RBV is often required. However, RBV dose reduction or discontinuation is uncommonly needed and do not impair the SVR rate.

Ledipasvir and tenofovir drug interaction in human immunodeficiency virus-hepatitis C virus coinfected patients: Impact on tenofovir trough concentrations and renal safety. Br J Clin Pharmacol 2018; 84:404-409.

Abstract
We evaluate the impact of ledipasvir on both tenofovir plasma trough concentration and estimated glomerular renal function in human immunodeficiency virus-hepatitis C virus coinfected patients receiving a tenofovir-based antiretroviral regimen and treated with ledipasvir/sofosbuvir. Twenty-six patients [81% male, median age: 51 years; hepatitis C virus genotype 1(75%)/4(15%)] were included. Tenofovir trough concentration (interquartile range) increased from 78 ng ml-1 (53-110) at baseline to 141 ng ml-1 (72-176) at 1 month (P = 0.003). No significant difference on estimated glomerular renal function using both Cockroft-Gault and Modification of Diet in Renal Disease formulae, respectively, [median (interquartile range)] was observed between baseline [101.3 ml min-1 (91.1-114.1); 95.6 ml min-1 (86.5-111.2)], 1 month [102.4 ml min-1 (89.8-112.9), P = 0.26; 92.5 ml min-1 (88.1-114.3), P = 0.27], end-of-treatment [96.5 ml min-1 (82.4-115.4), P = 0.39; 95.4 ml min-1 (84.2-105.4), P = 0.16] and 12 weeks after the end of treatment [100.5 ml min-1 (83.3-111.9), P = 0.24; 93.4 ml min-1 (82.2-103.5), P = 0.16]. Three patients progressed from chronic kidney disease stage 1 to stage 2 at 12 weeks post-treatment. A significant increase in tenofovir exposure through P-glycoprotein inhibition by ledipasvir was confirmed without significant impact on glomerular renal function in our population with normal renal function or mild renal impairment.

Abstract
Treatment of chronic hepatitis C virus (HCV) infection included use of pegylated interferon-based regimens before 2014 and direct-acting agents (DAA) since 2014 at the VA Medical Center in Washington, DC. We compared the continua of care between our HCV/HIV coinfected and HCV mono-infected patients during 2008-2015. A review of summary data from our local HCV Clinical Case Registry was conducted for the interferon treatment era (2008-2013) and the DAA era (2014-2015). Data were analyzed on a modified HCV Continuum of Care based on these stages: HCV diagnosis, engagement in medical care, HCV treatment, and HCV sustained virologic response (SVR) for differences between HCV/HIV coinfected and HCV mono-infected patients. All patients had 88% engagement in primary care during 2008-2013. HCV mono-infected and HCV/HIV coinfected patients had similar treatment (6% vs. 5%, p = .6622) and HCV SVR (1% vs. 0.5%, p = .1737) rates in the interferon era. However, more HCV/HIV coinfected patients were engaged in care (93% vs. 87%, p = .0044), accessed HCV treatment (36% vs. 23%, p < .0001), and achieved HCV SVR (31% vs. 21% p = .0002) compared to mono-infected patients in the DAA era. Both HCV/HIV coinfected and HCV mono-infected patients achieved higher SVR of ≥86% after DAA treatment. Although improvements were seen for treatment and SVR among HCV mono-infected patients, better rates for care engagement, HCV treatment, and SVR were realized for HCV/HIV coinfected patients in the DAA era.

Low prevalence of HCV infection with predominance of genotype 4 among HIV patients living in Libreville, Gabon. PLoS One 2018; 13:e0190529. [PMID: 29385148 PMCID: PMC5791959 DOI: 10.1371/journal.pone.0190529] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Accepted: 12/15/2017] [Indexed: 11/24/2022] Open
Abstract
Background Gabon is an endemic area for human immunodeficiency virus (HIV) and hepatitis C virus (HCV) and the risk of co-infection is high. Method Between November 2015 and April 2016, we conducted retrospective study on HCV infection among people living with HIV/AIDS (PLHA). A total of 491 PLHA were included in this study and tested for the presence of HCV infection. HIV viral loads were obtained using the Generic HIV viral Load® assay and the CD4+ T cells count was performed using BD FACSCount™ CD4 reagents. HCV screening was performed using the MP Diagnostics HCV ELISA 4.0 kit. HCV genotypes were determined by sequence analysis of NS5B and Core regions. The Mann-Whitney test was used to compare the groups. Chi-2 test and Fisher's Exact Test were used to compare prevalence. Results HCV seroprevalence was 2.9% (14/491), (95% confidence interval (CI):1.4–4.3%). The percentage of HCV viremic patients, defined by the detection of HCV RNA in plasma, was 57% (8/14), representing 1.6% of the total population. HCV seroprevalence and replicative infection were not statistically differ with gender. The percentage of co-infection increased with age. No correlation with CD4+ T cells count and HIV viral load level was registered in this study. Identified HCV strains were predominantly of genotype 4 (87.5%) including 4k, 4e, 4g, 4p, 4f and 4c subtypes. Only one strain belonged to genotype 2 (subtype 2q). Analysis of the NS5B region did not reveal the presence of resistance-associated substitutions for sofosbuvir. Conclusion A systematic screening of hepatitis C is therefore strongly recommended as well as genotyping of HCV strains in order to adapt treatments for the specific case of people living with HIV/AIDS in Central Africa.

Abstract
Direct-acting antiviral agents (DAAs) represent the major advance in hepatitis C virus (HCV) infection treatment leading to extremely high eradication rates in HCV mono- and HIV/HCV co-infected patients. In this scenery, availability of Therapeutic Drug Monitoring (TDM) is of interest to assess plasma concentrations to prevent either therapeutic failure due to suboptimal medication adherence and drug-drug interactions or avoid adverse events. Aim of this study was to develop and validate an Ultra-Performance Liquid Chromatography Mass Spectrometry (UPLC-MS/MS) method for the simultaneous quantification of sofosbuvir, sofosbuvir metabolite (GS-331007), and daclatasvir in human plasma. A simple protein precipitation was applied by adding 200 μL acetonitrile with internal standard 6,7-Dimethyl- 2,3-di(2-pyridyl) quinoxaline to 100 μL plasma sample. Drug separation was performed on analytical C-18 Luna Omega column (50 mm × 2.1 mm I.D.) with particle size of 1.6 μm. The mobile phase consisting of water containing 0.1% formic acid and acetonitrile at flow 0.4 mL/min and a gradient run time of 3.5 min. The injection volume was 10 μL. Anti-HCV drugs were detected in positive electrospray ionization mode. The full scan mass spectral analyses of sofosbuvir, GS-331007, daclatasvir and quinaxoline showed protonated molecule ions and transitions m/z: 530.098 → 243.02, 260.93 → 112.94, 739.4 → 339.27 and 313.03 → 77.99 respectively. The linearity of standard curves was excellent (r2 > 0.99), the absolute recovery of anti-HCV drugs ranged between 95 and 98%, and both imprecision and inaccuracy were <15% according to FDA guidelines. The UPLC-MS/MS method was applied to 16 plasma samples of as many HIV/HCV co-infected patients treated with sofosbuvir and daclatasvir. While sofosbuvir was not detectable in all samples, the median plasma concentrations of daclatasvir and GS-331007 were 223.6 ± 319.56 ng/mL and 537.11 ± 242.09 ng/mL, respectively. In conclusion, we describe an UPLC-MS/MS method allowing the simultaneous quantification of sofosbuvir, GS-331007 and daclatasvir in plasma samples. The method was sensitive, specific, robust, and time-saving.

Abstract
BACKGROUND To describe the use of nonantiretroviral comedication and combination antiretroviral therapy (cART) in patients coinfected with HIV/hepatitis C virus (HCV) and to predict the potential for drug-drug interactions (DDIs) with direct-acting antivirals (DAAs) against HCV. METHODS This is a retrospective, cross-sectional study, using the Dutch, nationwide ATHENA observational HIV cohort database. All patients with a known HIV/HCV coinfection on January 1, 2015, were included. Comedication and cART registered in the database were listed. The potential for DDIs between DAAs and comedication/cART were predicted using http://hep-druginteractions.org. DDIs were categorized as: (1) no clinically relevant DDI; (2) possible DDI; (3) contraindication; or (4) no information available. RESULTS We included 777 patients of whom 488 (63%) used nonantiretroviral comedication. At risk for a category 2/3 DDI with nonantiretroviral comedications were 299 patients (38%). Most DDIs were predicted with paritaprevir/ritonavir, ombitasvir ± dasabuvir (47% of the drugs) and least with grazoprevir/elbasvir (11% of the drugs). Concerning cART, daclatasvir/sofosbuvir is the most favorable combination as no cART is contraindicated with this combination. In genotype 1/4 patients, grazoprevir/elbasvir is least favorable as 75% of the patients must alter their cART. CONCLUSIONS This study showed that comedication use in the aging HIV/HCV population is frequent and diverse. There is a high potential for DDIs between DAAs and comedication/cART.

Abstract
Antiviral drugs for treatment of hepatitis C have grown dramatically in recent years. The emergence of direct antiviral agents (DAAs) is a major advance in hepatitis C treatment. Since the first generation DAAs appeared in 2011, two more generations of DAAs have been approved by the Food and Drug Administration in only five years. With the advantages of coverage of all genotypes, high availability and easy administration, DAAs have been widely used worldwide in recent years. DAAs have nearly solved the main problems encountered in hepatitis C antiviral therapy. However, adverse events associated with DAAs use have been reported constantly, and the safety of DAAs has attracted more and more attention. According to recent reports, the adverse reactions of DAAs have been gradually reduced from the first generation to the third generation. When combined with other drugs, the drug-drug interactions (DDIs) need special attention. In addition, the usage of DAAs in special patient groups should be cautious. In this paper, we will summarize the adverse effects and DDIs of DAAs as well as their usage in the general population and special patient groups.

Abstract
Therapy for human immunodeficiency virus (HIV) and chronic hepatitis C has evolved over the past decade, resulting in better control of infection and clinical outcomes; however, drug-drug interactions remain a significant hazard. Joint recommendations from the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America regarding drug-drug interactions between HIV antiretroviral agents and direct-acting antiviral agents for treatment of hepatitis C virus (HCV) infection are reviewed here. This review is oriented to facilitate appropriate selection of an antiviral therapy regimen for HCV infection based on the choice of antiretroviral therapy being administered and, if necessary, switching antiretroviral regimens.

Abstract
The direct-acting antiviral regimen of 25 mg ombitasvir-150 mg paritaprevir-100 mg ritonavir once daily (QD) plus 250 mg dasabuvir twice daily (BID) is approved for the treatment of hepatitis C virus genotype 1 infection, including patients coinfected with human immunodeficiency virus. This study was performed to evaluate the pharmacokinetic, safety, and tolerability effects of coadministering the regimen of 3 direct-acting antivirals with two antiretroviral therapies (dolutegravir or abacavir plus lamivudine). Healthy volunteers (n = 24) enrolled in this phase I, single-center, open-label, multiple-dose study received 50 mg dolutegravir QD for 7 days or 300 mg abacavir plus 300 mg lamivudine QD for 4 days, the 3-direct-acting-antiviral regimen for 14 days, followed by the 3-direct-acting-antiviral regimen with dolutegravir or abacavir plus lamivudine for 10 days. Pharmacokinetic parameters were calculated to compare combination therapy with 3-direct-acting-antiviral or antiretroviral therapy alone, and safety/tolerability were assessed throughout the study. Coadministration of the 3-direct-acting-antiviral regimen increased the geometric mean maximum plasma concentration (Cmax) and the area under the curve (AUC) of dolutegravir by 22% (central value ratio [90% confidence intervals], 1.219 [1.153, 1.288]) and 38% (1.380 [1.295, 1.469]), respectively. Abacavir geometric mean Cmax and AUC values decreased by 13% (0.873 [0.777, 0.979]) and 6% (0.943 [0.901, 0.986]), while those for lamivudine decreased by 22% (0.778 [0.719, 0.842]) and 12% (0.876 [0.821, 0.934]). For the 3-direct-acting-antiviral regimen, geometric mean Cmax and AUC during coadministration were within 18% of measurements made during administration of the 3-direct-acting-antiviral regimen alone, although trough concentrations for paritaprevir were 34% (0.664 [0.585, 0.754]) and 27% (0.729 [0.627, 0.847]) lower with dolutegravir and abacavir-lamivudine, respectively. All study treatments were generally well tolerated, with no evidence of increased rates of adverse events during combination administration. These data indicate that the 3-direct-acting-antiviral regimen can be administered with dolutegravir or abacavir plus lamivudine without dose adjustment.

Abstract
BACKGROUND Shortening the duration of treatment with HCV direct-acting antivirals (DAAs) leads to substantial cost reductions. According to the label, sofosbuvir and ledipasvir can be prescribed for 8 weeks (SL8) in noncirrhotic women or men with HCV genotype 1 and low viral loads. However, real-world data about the efficacy and safety of SL8 are largely missing. METHODS Interim results from an ongoing prospective, multicenter cohort of 9 treatment centers in Germany (GECCO). All patients started on treatment with HCV DAAs since January 2014 were included. This report describes safety and efficacy outcomes in 210 patients with HCV monoinfection and 35 with human immunodeficiency virus (HIV)-HCV coinfection given SL8 in a real-world setting. RESULTS Of 1353 patients included into the GECCO cohort until December 2015, a total of 1287 had complete data sets for this analysis; 337 (26.2%) fulfilled the criteria for SL8 according to the package insert, but only 193 (57.2%) were eventually treated for 8 weeks. Another 52 patients did not fulfill the criteria but were treated for 8 weeks. SL8 was generally well tolerated. The overall sustained virologic response rate 12 weeks after the end of treatment was 93.5% (186 of 199). The on-treatment response rate was 99.4% (159 of 160) in HCV-monoinfected and 96.4% (27 of 28) in HIV-HCV-coinfected patients. Ten patients were lost to follow-up. CONCLUSIONS SL8 seems highly effective and safe in well-selected HCV-monoinfected and HIV-HCV-coinfected patients in a real-world setting.

Abstract
BACKGROUND For liver transplant recipients with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection, recurrence after LT is associated with a higher risk of graft loss than for HCV mono-infected patients. Prior HCV treatment options were limited by side effects and drug-drug interactions. AIM To evaluate treatment outcomes with sofosbuvir (SOF)-based therapy among HIV/HCV coinfected liver transplant recipients. METHODS Access to SOF and ribavirin (RBV) prior to regulatory approval was attained via an international compassionate access program for transplant recipients with a life expectancy of 1 year or less in the absence of HCV treatment. This report focuses on the short and longer term outcomes in HCV-HIV co-infected liver transplant recipients. RESULTS Twenty patients were treated, nine with early severe recurrence and 11 with cirrhosis. Eleven patients received SOF and RBV, one SOF, RBV and Peg-interferon, three SOF, RBV and simeprevir and five SOF, RBV and daclatasvir. Of the 18 patients who completed treatment, 16 (89%) achieved sustained virological response 12 weeks after the end of treatment (SVR12). Liver function tests (including bilirubin and albumin) improved significantly over time. Nineteen serious adverse events occurred in eight (40%) patients, none of them related to SOF. Two patients died during treatment and another, 1 year after the end of therapy, due to progressive end-stage liver disease. Importantly, HIV suppression was not compromised. No significant drug-drug interactions were reported. CONCLUSIONS Sofosbuvir-based regimens are safe, well-tolerated and provide high rates of SVR in HCV-HIV co-infected patients with severe recurrence after-liver transplant.

Abstract
INTRODUCTION Hepatitis C virus (HCV) is a chronic infection that disproportionately impacts people living with HIV. In the past, HCV therapy was less effective in individuals with HIV co-infection. However, the advent of direct-acting antivirals has revolutionized HCV treatment with high rates of success in patients both with and without HIV. AREAS COVERED In this paper, we review the evidence supporting the use of ledipasvir and sofosbuvir (LDV/SOF) for the treatment of HCV in patients with HIV co-infection. Articles searchable on MEDLINE/PubMed were reviewed to provide context for use of LDV/SOF in individuals with HCV and HIV co-infection. EXPERT OPINION This treatment is highly effective in achieving HCV cure or sustained virologic response, however further studies need to done to address efficacy of treatment in people with uncontrolled HIV, concerns regarding drug-interactions with antiretroviral therapy, and potential for shorter duration treatment.
