Clin Mol Hepatol 2017; 23:316-322. [PMID: 28827512 PMCID: PMC5760003 DOI: 10.3350/cmh.2016.0087] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Revised: 05/04/2017] [Accepted: 06/19/2017] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND/AIMS Treatment of chronic hepatitis C virus (HCV) infection in patients with chronic kidney disease (CKD) is essential. The availability of sofosbuvir (SOF) has dramatically improved overall HCV cure rates, however there is insufficient data regarding its use in patients with CKD. We evaluated SOF in patients with hepatitis C genotype 1 (G1) and moderately impaired renal function. METHODS We retrospectively reviewed all patients treated with a SOF-based regimen from December 2013 through September 2015 at Virginia Mason Medical Center. Data was then collected for HCV G1 patients with stage 3 CKD. RESULTS A total of 28 patients with HCV G1 and stage 3 CKD were treated with a SOF-based regimen. Twenty-one patients had stage 3A CKD (estimated glomerular filtration rate [eGFR] 45-60 mL/min/1.73m2) and 7 patients had stage 3B CKD (eGFR 30-45 mL/min/1.73m2). The overall rate of sustained virologic response (SVR) 12 weeks after completion of therapy (SVR12) was 85.7% (24/28). SVR12 in stage 3A CKD patients was 81.0% (17/21) and in stage 3B CKD patients, SVR12 was 100% (7/7). Based on the treatment regimen used, the SVR12 was 81.8% (9/11), 92.3% (12/13), and 75.0% (3/4) for SOF/ledipasvir (LDV), SOF/simeprevir (SIM), and SOF/pegylated interferon (PEG)/ribavirin (RBV), respectively. Greater than 30% reduction eGFR was observed in 4 out of 28 patients. CONCLUSIONS SOF-based regimens resulted in high SVR12 rates in patients with moderately impaired renal function. During therapy, HCV patients with CKD should be carefully monitored for worsening renal function.

Abstract
Chronic hepatitis C virus (HCV) infection remains a leading cause of chronic liver disease in the United States. Although the hepatic impact of chronic HCV leading to cirrhosis and the need for liver transplantation is paramount, the extrahepatic manifestations of chronic HCV infection are equally important. In particular, a better understanding of the prevalence and impact of extrahepatic manifestations of chronic HCV infection in the post-liver transplant setting relies on understanding the interplay between the effects of chronic HCV infection in a posttransplant environment characterized by strong immunosuppression and the associated risks of this milieu.

Abstract
The prevalence of hepatitis C virus (HCV) infection amongst patients with chronic kidney disease (CKD) and end-stage renal disease exceeds that of the general population. In addition to predisposing to the development of cirrhosis and hepatocellular carcinoma, infection with HCV has been associated with extra-hepatic complications including CKD, proteinuria, glomerulonephritis, cryoglobulinemia, increased cardiovascular risk, insulin resistance, and lymphoma. With these associated morbidities, infection with HCV is not unexpectedly accompanied by an increase in mortality in the general population as well as in patients with kidney disease. Advances in the understanding of the HCV genome have resulted in the development of direct-acting antiviral agents that can achieve much higher sustained virologic response rates than previous interferon-based protocols. The direct acting antivirals have either primarily hepatic or renal metabolism and excretion pathways. This information is particularly relevant when considering treatment in patients with reduced kidney function. In this context, some of these agents are not recommended for use in patients with a glomerular filtration rate < 30 mL/min per 1.73 m2. There are now Food and Drug Administration approved direct acting antiviral agents for the treatment of patients with kidney disease and reduced function. These agents have been demonstrated to be effective with sustained viral response rates comparable to the general population with good safety profiles. A disease that was only recently considered to be very challenging to treat in patients with kidney dysfunction is now curable with these medications.

Abstract
Over the past few years, treatment options for chronic hepatitis C virus (HCV) infection have evolved dramatically. The current approved interferon-free direct-acting antiviral (DAA) regimens have been shown to be safe and effective with sustained virologic response (SVR) rates of >90% in most patients. Unique issues yet remain such as the challenges in patients with impaired renal function or decompensated cirrhosis. Patients with stages 4-5 chronic kidney disease (CKD) have a higher prevalence of HCV infection compared with the general population. Chronic HCV in those on dialysis and in kidney transplant recipients is associated with higher morbidity and mortality than uninfected patients. The HCV-infected population is also at risk of developing extrahepatic manifestations associated with altered immune system function and chronic inflammation with cryoglobulinaemic vasculitis being the most common of these manifestations. Therefore, patients with CKD stages 4-5 have to be considered priority patients for HCV therapy. New antiviral therapies have the potential to improve outcomes in this vulnerable patient population, including those on haemodialysis. Recently published studies conducted in kidney transplant recipients have demonstrated successful outcomes. It is thus essential that we carefully select the most appropriate DAA regimen and the best time for treatment in the context of kidney transplantation or cryoglobulinaemic vasculitis. While sofosbuvir, the only approved nucleotide NS5B inhibitor, has been the backbone of most pangenotypic therapeutic regimens, it has a limitation in those with advanced kidney disease. The currently approved regimens for those with stage 4/5 CKD, while effective, have challenges in that they apply to genotype 1/4 and may require RBV for genotype 1a. Globally, genotype 3 is a common infection, and thus, this group with CKD presents a huge unmet need for effective therapies. As therapy of HCV in renal transplant recipients has been highly successful, it provides an opportunity to expand the use of HCV-infected organs in solid organ transplantation.

Abstract
Among patients with chronic kidney disease (CKD) in the United States, HCV infection causes significant morbidity and mortality and results in substantial healthcare costs. A once-daily oral regimen of elbasvir/grazoprevir (EBR/GZR) for 12 weeks was found to be a safe and efficacious treatment for HCV in patients with CKD. We evaluated the cost-effectiveness of EBR/GZR in treatment-naïve and treatment-experienced CKD patients compared with no treatment (NoTx) and pegylated interferon plus ribavirin (peg-IFN/RBV) using a computer-based model of the natural history of chronic HCV genotype 1 infection, CKD and liver disease. Data on baseline characteristics of the simulated patients were obtained from NHANES, 2000-2010. Model inputs were estimated from published studies. Cost of treatment with EBR/GZR and peg-INF/RBV were based on wholesale acquisition cost. All costs were from a third-party payer perspective and were expressed in 2015 U.S. dollars. We estimated lifetime incidence of liver-related complications, liver transplantation, kidney transplantation, end-stage live disease mortality and end-stage renal disease mortality; lifetime quality-adjusted life years (QALY); and incremental cost-utility ratios (ICUR). The model predicted that EBR/GZR will significantly reduce the incidence of liver-related complications and prolong life in patients with chronic HCV genotype 1 infection and CKD compared with NoTx or use of peg-IFN/RBV. EBR/GZR-based regimens resulted in higher average remaining QALYs and higher costs (11.5716, $191 242) compared with NoTx (8.9199, $156 236) or peg-INF/RBV (10.2857, $186 701). Peg-IFN/RBV is not cost-effective, and the ICUR of EBR/GZR compared with NoTx was $13 200/QALY. Treatment of a patient on haemodialysis with EBR/GZR resulted in a higher ICUR ($217 000/QALY). Assuming a threshold of $100 000 per QALY gained for cost-effectiveness, use of elbasvir/grazoprevir to treat an average patient with CKD can be considered cost-effective in the United States.

Sofosbuvir and Velpatasvir Combination Improves Patient-reported Outcomes for Patients With HCV Infection, Without or With Compensated or Decompensated Cirrhosis. Clin Gastroenterol Hepatol 2017; 15:421-430.e6. [PMID: 27847279 DOI: 10.1016/j.cgh.2016.10.037] [Citation(s) in RCA: 62] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 10/14/2016] [Accepted: 10/31/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The combination of sofosbuvir and velpatasvir is used to treat patients with hepatitis C virus (HCV) infection of different genotypes. We compared the effects of this treatment regimen, with and without ribavirin, on outcomes reported by patients (patient-reported outcomes [PROs]) with HCV infection, with or without cirrhosis. METHODS We performed a post hoc analysis of data collected from phase 3 clinical trials (ASTRAL-1, -2, -3, and -4) of 1701 patients infected with HCV of different genotypes treated with sofosbuvir and velpatasvir with ribavirin for 12 weeks (n = 87), sofosbuvir with ribavirin for 12 or 24 weeks (n = 401), and ribavirin-free sofosbuvir and velpatasvir for 12 or 24 weeks (n = 1213). In all trials, participants completed 4 PRO questionnaires (while blinded to their HCV RNA levels): the Short Form-36, the Functional Assessment of Chronic Illness Therapy-Fatigue, the Chronic Liver Disease Questionnaire-HCV Version, and the Work Productivity and Activity Impairment: Specific Health Problem, at multiple time points. We compared baseline PROs and changes in PROs following treatment in patients without cirrhosis (n = 1112), with compensated cirrhosis (n = 338), and with decompensated cirrhosis (n = 251). RESULTS Baseline PRO scores were as much as 33.5% lower in patients with decompensated cirrhosis than in patients without cirrhosis (P < .05). Following treatment with ribavirin-containing regimens, changes in PRO scores were similar among patients with compensated and decompensated cirrhosis (all P > .01). Treatment with these regimens increased some PRO scores by as much as 11.8% from baseline (P < .05) and reduced others, by as much as 7.1% (P < .05). Despite this, by 12 weeks after cessation of treatment with ribavirin-containing regimens, all PRO decrements resolved; PRO scores increased by as much as 14.2%, and as much as 17.1% at 24 weeks after treatment, regardless of cirrhosis status (all P > .01 between cirrhosis groups). In contrast, treatment with ribavirin-free sofosbuvir and velpatasvir increased PRO scores for patients with compensated cirrhosis, and even more so in patients with decompensated cirrhosis starting at treatment Week 4; no statistically significant decrement was observed at any time point (all 1-sided P values > .05). In multivariate analysis, compensated cirrhosis was associated with a 2.3% to 5.0% greater increase in PRO scores following treatment with sofosbuvir and velpatasvir (P < .05); decompensated cirrhosis was associated with a 5.5%-9.1% greater increase (P < .002). Clinicaltrials.gov number, NCT02201940, NCT02220998, NCT02201953, NCT02201901. CONCLUSIONS In an analysis of data from 4 phase 3 clinical trials, we found that patients with HCV infection (especially those with decompensated cirrhosis) have significant increases in their PRO scores during treatment with sofosbuvir and velpatasvir and after achieving a sustained virologic response.

Abstract
Background and Objectives: Hepatitis C and chronic kidney disease (CKD) are major global health problems and are highly prevalent in Pakistan. There is limited information on prevalence of hepatitis C in patients with CKD not yet on dialysis. The objective of this study was to determine the frequency of hepatitis C in hospitalized chronic kidney disease patients at a tertiary care center in Pakistan. Methods: The study design was cross-sectional in nature. Patients between ages of 20-80 years with CKD not previously on renal replacement therapy and who were admitted to nephrology ward at a tertiary care facility were included. Hepatitis C was tested using 3rd generation enzyme linked immunosorbent assay (ELISA). Hepatitis C RNA was tested by polymerase chain reaction (PCR) in patients with positive ELISA. Results: A total of 180 patients were included in the study. Mean age of patients was 48.7±14.9 years. Of all patients, 105 (58.3%) were males and 75 (41.7%) were females, 152 (84.4%) had hypertension, 113 (62.8%) had diabetes mellitus and 26 (14.9%) had known cardiovascular disease. Mean eGFR of patients was 11.4±9.4 ml/min/1.73 m2. Of all patients with CKD, 49 (27.2%) had hepatitis C test positive by ELISA. Hepatitis C PCR testing was done in 39 patients with hepatitis C ELISA positive status and 29 (74.4%) tested positive. Risk factors and clinical characteristics of patients with and without positive hepatitis C antibody by ELISA were similar. Conclusion: A significant proportion of hospitalized CKD patients have hepatitis C. Strict universal infection control measures should be implemented in nephrology wards to prevent transmission of hepatitis C infection.

Abstract
In hepatitis C virus (HCV)-infected patients, transplantation can be justified by decompensated cirrhosis, hepatocellular carcinoma (HCC) or both. During the last decade, HCV infection accounted for about 30% of the indications for transplantation in Europe and North America. Direct antiviral agents (DAAs) are highly effective at curing HCV, even in patients with end-stage cirrhosis. In the future, the incidence of HCV-related decompensated cirrhosis will continue to decrease. The incidence of HCC will also decrease, but a large cohort of patients with cirrhosis will still be at risk of developing HCC even after HCV has been cured. They will continue to represent potential candidates for transplantation. Overall, HCV will account for a significantly lower proportion of indications for transplantation in the future. However, generalization of DAAs is unlikely to affect the total transplantation volume as the gap between donors and potential recipients markedly exceeds 30%. In addition, non-alcoholic steatohepatitis (NASH) is a rapidly growing indication for transplantation. The high barrier to resistance nucleos(t)ide analogues (NUCs) have been used for several years to treat hepatitis B virus (HBV) infection. Decompensated HBV cirrhosis now represents a very uncommon indication for transplantation. HCC remains the leading indication in HBV-infected patients awaiting transplantation. NUCs plus anti-HBs immune globulins or NUCs alone are highly effective at preventing post-transplant HBV recurrence. However, continuous prophylaxis is still needed as extrahepatic HBV particles persist with a potential for recurrence. Post-transplant immunosuppression facilitates recurrence. In the future, an important challenge will be to cure HBV by eliminating residual HBV particles.

Abstract
Chronic hepatitis C virus (HCV) infection is burdensome in patients with chronic kidney disease and contributes to substantial liver-related and all-cause morbidity and mortality. HCV infection itself may cause kidney dysfunction, as exemplified through mixed cryoglobulinemic vasculitis. HCV is more prevalent in patients with significant kidney disease compared to the general population, and recent reports have shown inadvertent HCV transmission in U.S. hemodialysis centers. Further, HCV has been demonstrated to accelerate kidney dysfunction and is associated with worse clinical outcomes in patients with kidney disease. As such, the HCV-infected population with concurrent kidney disease is an important patient subgroup that warrants focused medical care and attention. With the advent of direct-acting antivirals (DAAs), the successful treatment of HCV is now a medical reality for many patients. Nuances in regimen selection and timing need to be considered when treating those with kidney dysfunction, particularly for those considering kidney transplantation.

Abstract
Hepatitis C virus (HCV) mainly targets the liver but can also induce extrahepatic manifestations. The kidney may be impacted via an immune mediated mechanism or a cytopathic effect. HCV patients are clearly at a greater risk of chronic kidney disease (CKD) than uninfected patients are, and the presence of CKD increases mortality. Interferon-based therapies and ribavirin are difficult to manage and are poorly effective in end-stage renal disease and hemodialysis. These patients should be given priority treatment with new direct anti-viral agents (DAAs) while avoiding peginterferon and ribavirin. The first results were convincing. To aid in the correct use of these drugs in patients with renal insufficiency, their pharmacokinetic properties and potential renal toxicity must be known. The renal toxicity of these new drugs was not a safety signal in clinical trials, and the drugs are generally efficient in these frail populations. These drugs are usually well tolerated, but recent cohort studies have demonstrated that these new regimens may be associated with renal side effects, especially when using sofosbuvir combinations. HCV, renal diseases and comorbidities are intimately linked. The close monitoring of renal function is required, particularly for at-risk patients (transplanted, HIV-coinfected, CKD, hypertensive or diabetic patients). New DAA regimens, which will soon be approved, will probably change the landscape.

Abstract
Hepatitis C virus infection (HCV) affects approximately 170-200 million individuals globally. HCV is one of the primary causes of hepatocellular carcinoma (HCC) and cirrhosis and has been identified as the leading indication for liver transplantation in most Western countries. Because HCV is a systemic disease with hepatic, extrahepatic, economic and patient reported consequences, it is important for healthcare practitioners to understand the comprehensive and multi-faceted picture of this disease. In this context, it is important to fully appreciate the impact of HCV on the individual patient and the society. With the recent advent of the new generation of direct antiviral agents, the long standing goal of eradicating HCV in most infected patients has been accomplished. Therefore, now more than ever, it is critical to assess the total benefits of sustained virological response in a comprehensive manner. This should not be limited to the clinical benefits of HCV cure, but also to account for the improvement of patient reported health and economic outcomes of HCV cure. It is only through this comprehensive approach to HCV and its treatment that we will understand the full impact of this disease and the tremendous gains that have been achieved with the new antiviral regimens.

[PMID: 27641990 DOI: 10.1016/j.jhep.2016.06.011] [Citation(s) in RCA: 71] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2016] [Revised: 06/06/2016] [Accepted: 06/07/2016] [Indexed: 12/18/2022]
Abstract
Hepatitis C virus (HCV) infection is associated with tremendous morbidity and mortality due to liver complications. HCV infection is also associated with many extrahepatic manifestations including cardiovascular diseases, glucose metabolism impairment, cryoglobulinemia vasculitis, B cell non-Hodgkin lymphoma and chronic kidney disease (CKD). Many studies have shown a strong association between HCV and CKD, by reporting (i) an increased prevalence of HCV infection in patients on haemodialysis, (ii) an increased incidence of CKD and proteinuria in HCV-infected patients, and (iii) the development of membranoproliferative glomerulonephritis secondary to HCV-induced cryoglobulinemia vasculitis. HCV seropositivity is found to be associated with an increased relative risk for all-cause and cardiovascular mortality in the dialysis population. HCV seropositivity is linked to lower patient and graft survival after kidney transplantation. Such poor HCV-associated prognosis should have encouraged clinicians to treat HCV in CKD patients. However, due to frequent side effects and the poor efficacy of interferon-based treatments, very few HCV dialysis patients have received HCV medications until now. The emergence of new direct acting, interferon-free antiviral treatment, leading to HCV cure in most cases with a satisfactory safety profile, will shortly modify the management of HCV infection in CKD patients. In patients with a glomerular filtration rate (GFR) >30ml/min, the choice of DAA is not restricted. In those with a GFR <30 and >15ml/min, only paritaprevir/ritonavir/ombitasvir/dasabuvir or a grazoprevir plus elbasvir regimen are approved. In patients with end stage renal disease (GFR <15ml/min or dialysis), current data only allows for the use of a grazoprevir plus elbasvir combination. No doubt these data will be modified in the future with the advent of new studies including larger cohorts of HCV patients with renal impairment.

Abstract
Soon after the hepatitis C virus (HCV) was identified in 1989, it was recognized that the prevalence of infection in patients with ESRD far exceeded that in the general population. Infection with HCV predisposes to the hepatic complications of cirrhosis and hepatocellular carcinoma. However, important extrahepatic manifestations include immune complex glomerular disease, accelerated progression of CKD, increases in cardiovascular event risk, and lymphoproliferative disorders. Advances in understanding the molecular biology of HCV have ushered in a new era in the treatment of this infection. Second generation direct-acting antiviral agents have revolutionized therapy, with sustained virologic response rates (undetectable viral load 12 weeks after completing therapy) of >90% in most patients. Studies using direct-acting antivirals in patients with CKD and those on dialysis are showing excellent safety and efficacy as well. In this context, it is imperative that nephrologists become familiar with this literature, reviewed here, so that the important decisions, including which patients should be treated and the optimal timing to initiate therapy, are vetted in association with the compounding issues of CKD, ESRD, and kidney transplantation.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) infection has hepatic and extrahepatic manifestations with various costs and impairments to health-related quality of life (HRQL). We performed a meta-analysis to determine the prevalence of extrahepatic manifestations in patients with HCV infection, how these impair HRQL, and their costs. METHODS We performed systematic reviews of the literature using MEDLINE, CINAHL, and the Cochrane Systematic Review Database, from 1996 through December 2014, to identify studies of the following extrahepatic manifestations of HCV infection: mixed cryoglobulinemia, chronic kidney or end-stage renal disease, type 2 diabetes, B-cell lymphoma, lichen planus, Sjögren's syndrome, porphyria cutanea tarda, rheumatoid-like arthritis, or depression. We performed a separate meta-analysis for each condition to determine prevalence rates of extrahepatic manifestations of HCV infection and their effects on HRQL. We determined the annual costs (inpatient, outpatient, and pharmacy) associated with extrahepatic manifestations of HCV infection. RESULTS In an analysis of data from 102 studies, we found the most common extrahepatic manifestations to be diabetes (in 15% of patients) and depression (in 25% of patients). HRQL data showed that HCV infection had negative effects on overall physical and mental health. Total direct medical costs of extrahepatic manifestations of HCV infection, in 2014 US dollars, were estimated to be $1506 million (range, $922 million-$2208 million in sensitivity analysis). CONCLUSIONS In a systematic review and meta-analysis we determined the prevalence, risks, and costs associated with extrahepatic manifestations of HCV infection. These estimates should be added to the liver-related burden of disease to obtain a more accurate assessment of the total burden of chronic HCV infection. Prospective, real-world studies are needed to increase our understanding of the total clinical and economic effects of HCV infection and treatment on patients and society.

Abstract
BACKGROUND AND AIMS We aimed to assess the incidence and progression of chronic kidney disease (CKD) following hepatitis C virus (HCV) seroconversion. METHODS This retrospective cohort study included Veterans with a confirmed HCV seroconversion between 2001 and 2014 and Veterans with negative HCV testing over the same time period. The outcomes included development of advanced CKD (eGFR < 60 mL/min/1.73 m(2) on two separate occasions at least 90 days apart, plus a ≥ 10 mL/min/1.73 m(2) decline from baseline) and progressive CKD (decline in eGFR of ≥ 30 mL/min/1.73 m(2) from baseline). Multivariable Cox proportional hazards models were used to evaluate the association between HCV and incident advanced and progressive CKD. RESULTS The final cohort consisted of 71,528 Veterans, including 2589 with recently seroconverted HCV. Over a mean follow-up of 6 years, 36% of patients with and 31% without HCV developed advanced CKD (p < 0.001), and 35% of patients with vs. 26% without HCV developed progressive CKD (p < 0.001). After controlling for traditional risk factors, recently seroconverted HCV+ patients were significantly less likely to develop advanced CKD (HR 0.86; 95% CI 0.79, 0.92), and HCV status was not significantly associated with progressive CKD (HR 0.93; 95% CI 0.86, 1.00). Factors associated with developing advanced and progressive CKD included older age, female sex, diabetes, hypertension, development of cirrhosis, and substance abuse. CONCLUSIONS In this cohort of newly infected US Veterans, HCV infection was associated with decreased incidence of advanced and unchanged risk of progressive CKD, suggesting a larger role for traditional risk factors in the development of CKD after HCV seroconversion.

Abstract
Chronic hepatitis C (CHC) is significantly associated with a risk of renal deterioration over time. Renal impairment, especially stage 4-5 chronic kidney disease, increases the risk of: (i) the prevalence and incidence (in dialysis/transplantation) of hepatitis C virus (HCV) infection; (ii) liver deterioration during kidney transplantation and (iii) allograft failure and patient mortality. HCV-infected dialysis patients have a higher mortality than non-infected dialysis patients and than HCV-infected kidney recipients. The harmful impact of HCV emphasizes the need for oral antiviral therapies in patients with chronic kidney disease. Symptomatic cryoglobulinemic vasculitis and extensive liver fibrosis are already approved indications for early access to oral antiviral treatment. Patients with stage 4-5 chronic kidney disease should also be given priority: dialysis patients (whatever the stage of fibrosis and whether or not they are candidates for kidney transplantation) as well as all kidney recipients. The results of treatment of HCV with direct-acting antiviral (DAAs) drugs in patients with late chronic kidney disease are excellent, similar to those in the general population, although additional clinical trials are definitely needed, particularly to optimize adjustment of treatment to kidney function and determine the risk of drug-drug interactions.
