Utilization of HCV Viremic Kidneys with Genotyping/Subtyping-Free Sofosbuvir/Velpatasvir Treatment Strategy: Experience from China. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3758744. [PMID: 35941983 PMCID: PMC9356870 DOI: 10.1155/2022/3758744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 06/26/2022] [Accepted: 07/12/2022] [Indexed: 11/18/2022]
Abstract
Background. Owing to the advent of pangenotypic direct-acting antiviral agents (DAAs) for hepatitis C virus (HCV) treatment, utilization of HCV-infected deceased donor kidneys with simplified genotyping/subtyping-free sofosbuvir/velpatasvir (SOF/VEL) treatment strategy is now becoming a promising strategy for expanding the organ donor pool. Methods. This retrospective, comparative, single-center study included HCV viremic donor kidneys that were transplanted to 9 HCV-positive (HCV Ab-positive) recipients (D+/R+ group) and 14 HCV-negative recipients (D+/R- group) from May 2018 to January 2021. Both groups received prophylaxis with SOF/VEL treatment within 1-week posttransplant devoid of HCV genotyping/subtyping. The primary outcomes were sustained virologic response 12 weeks after completion of therapy (SVR12) and graft survival at 1-year posttransplant. Results. Baseline characteristics were similar between the HCV D+/R- and D+/R+ groups. The mean age of all recipients was
(SD) years, and 73.9% were male. A total of 92.9% (13 out of 14) recipients had pretreatment HCV viremia in the D+/R- group. The pretreatment HCV viral load in the D+/R+ group (5.98, log 10 IU/mL; IQR, 5.28-6.53) was significantly higher than that in the D+/R- group (3.61, log 10 IU/mL; IQR, 2.57-4.57). After SOF/VEL treatment, SVR12 was achieved in all recipients, with a 100% 1-year patient and graft survival rates. The D+/R+ group had a higher incidence of abnormal liver function (44.4% vs. 7.1%). No significant difference was observed between the two groups in terms of DGF, acute rejection, ALT, serum creatinine, and eGFR within 1-year posttransplant. No severe adverse events associated with either HCV viremia or SOF/VEL were observed. Conclusions. Using a simplified genotyping/subtyping-free SOF/VEL treatment strategy, kidneys from hepatitis C viremic donors for both infected and uninfected recipients presented with safe, excellent, and comparable 1-year outcomes, which can safely expand the donor pool. HCV-positive donor kidneys should be utilized regularly, regardless of the recipient’s HCV status.

Abstract
Background: Donor hepatitis-C (HCV) infection has historically represented a barrier to kidney transplantation (KT). However, direct-acting antiviral (DAA) medications have revolutionised treatment of chronic HCV infection. Recent American studies have demonstrated that DAA regimes can be used safely peri-operatively in KT to mitigate HCV transmission risk. Methods: To formulate this narrative review, a comprehensive literature search was performed to analyse results of existing clinical trials examining KT from HCV-positive donors to HCV-negative recipients with peri-operative DAA regimes. Results: 13 studies were reviewed (11 single centre, four retrospective). Outcomes for 315 recipients were available across these studies. A sustained virological response at 12 weeks (SVR12) of 100% was achieved in 11 studies. One study employed an ultra-short DAA regime and achieved an SVR12 of 98%, while another achieved SVR12 of 96% due to treatment of a missed mixed genotype. Conclusion: HCV+ KT is safe and may allow increased utilisation of organs for transplantation from HCV+ donors, who often have other favourable characteristics for successful donation. Findings from US clinical trials can be applied to the United Kingdom transplant framework to improve organ utilisation as suggested by the NHSBT vision strategy "Organ Donation and Transplantation 2030: meeting the need".

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
Kidney transplantation is the treatment of choice in end-stage renal disease. The main issue which does not allow to utilize it fully is the number of organs available for transplant. Introduction of highly effective oral direct-acting antivirals (DAAs) to the treatment of chronic hepatitis C virus infection (HCV) enabled transplantation of HCV viremic organs to naive recipients. Despite an increasing number of reports on the satisfying effects of using HCV viremic organs, including kidneys, they are more often rejected than those from HCV negative donors. The main reason is the presence of HCV viremia and not the quality of the organ. The current state of knowledge points to the fact that a kidney transplant from an HCV nucleic acid testing positive (NAT+) donor to naive recipients is an effective and safe solution to the problem of the insufficient number of organs available for transplantation. It does not, however, allow to draw conclusions as to the long-term consequence of such an approach. This review analyzes the possibilities and limitations of the usage of HCV NAT + donor organs.

Abstract
Drug overdoses have tripled in the United States over the last two decades. With the increasing demand for donor organs, one potential consequence of the opioid epidemic may be an increase in suitable donor organs. Unfortunately, organs from donors dying of drug overdose have poorer utilization rates than other groups of brain-dead donors, largely due to physician and recipient concerns about viral disease transmission. During the study period of 2011 to 2016, drug overdose donors (DODs) account for an increasingly greater proportion of the national donor pool. We show that a novel model of donor care, known as specialized donor care facility (SDCF), is associated with an increase in organ utilization from DODs compared to the conventional model of hospital-based donor care. This is likely related to the close relationship of the SDCF with the transplant centers, leading to improved communication and highly efficient donor care.

Abstract
Despite significant advances in transplantation of HIV-infected individuals, little is known about HIV coinfected patients with hepatitis C virus (HCV) genotypes other than genotype 1, especially when receiving HCV-infected organs with a different genotype. We describe the first case of kidney transplantation in a man coinfected with hepatitis C and HIV in our state. To our knowledge, this is also the first report of an HIV/HCV/HBV tri-infected patient with non-1 (2a) HCV genotype who received an HCV-infected kidney graft with the discordant genotype (1a), to which he converted after transplant. Our case study highlights the following: (1) transplant centers need to monitor wait times for an HCV-infected organ and regularly assess the risk of delaying HCV antiviral treatment for HCV-infected transplant candidates in anticipation of the transplant from an HCV-infected donor; (2) closer monitoring of tacrolimus levels during the early phases of anti-HCV protease inhibitor introduction and discontinuation may be indicated; (3) donor genotype transmission can occur; (4) HIV/HCV coinfected transplant candidates require a holistic approach with emphasis on the cardiovascular risk profile and low threshold for cardiac catheterization as part of their pretransplant evaluation.

Abstract
Background Long-term outcome of DAAs therapy in kidney transplant recipients was unknown. Thus, we aimed to evaluate it in a Chinese cohort of HCV-infected kidney transplant recipients. Methods Single-center and retrospective study of HCV-infected kidney transplant recipients initiating an DAAs regimen between January 2015 and December 2017 was conducted. Totally 26 KTX recipients were divided into three groups, including KTX-HD Group, DAA-KTX Group and KTX-DAA Group. On-treatment response was defined as target not detected within 12 weeks. SVR 48, 96 were defined as HCV-RNA negativity 48, 96 weeks after treatment cessation, respectively. Results HCV genotype was predominantly 1b (80.8%), followed by 2a. All (100%) patients achieved on-treatment response. Time to first TnD was 1.9 ± 0.6 weeks, with no significant difference among the three groups. All patients achieved SVR, with an SVR rate of 100.0% (26/26) among the patients who were followed up over 48 weeks after treatment cessation, and the same SVR rate (24/24) among the patients who were followed up over 96 weeks. Trough levels of Tac remained stable under DAAs therapy, without any dose adjustment. Two patients with abnormal GFR before treatment experienced serum creatinine elevation. Other adverse events included nausea, diarrhea, acid regurgitation, bilirubin elevation and edema of lower limbs. All patients recovered after treatment cessation without reductions in dose, or withdrawal of DAAs or immunosuppressive agents. Conclusions HCV genotype 1b and 2a are the only genotypes and 1b is predominant in our center. Antiviral treatment with DAAs in HCV-infected kidney transplant recipients is persistently effective and well tolerated during long-term follow-up. A regular monitoring of renal function in patients who receive DAAs regimens with preexisting impaired renal function is strongly recommended. Furthermore, the trough CNIs levels were recommended to be frequently monitored.

Abstract
Hepatitis C virus (HCV) is a common cause of increased morbidity and mortality in kidney transplant patients. It is associated with posttransplant glomerulonephritis, chronic allograft nephropathy, and New Onset Diabetes after Transplant (NODAT). In the past, HCV was difficult to treat due to the presence of interferon alpha-based therapies that were difficult to tolerate and were associated with adverse side-effects, such as the risk of rejection. With the advent of oral directly acting antiviral therapies, the landscape for HCV and transplantation has changed. These agents are highly effective and well tolerated with minimal side-effects. Sustained viral response rates in excess of 90% are achieved with most current treatment regimens active against all HCV genotypes. These new agents may show an improvement in graft and patient survival while essentially eliminating the risk of acute rejection from the use of prior interferon-based HCV therapies. These agents may also result in an improvement in organ allocation for HCV donor/HCV recipient transplantation. This review is meant to discuss the epidemiology of HCV, the new oral direct-acting antiviral agents (DAAs) and future opportunities for research in the field of HCV related transplantation.

Abstract
Hepatitis C virus (HCV) infection is prevalent in patients with kidney disease including transplant candidates and recipients. It is associated with increased morbidity and mortality in end-stage renal disease patients and also increases the risk of allograft rejection and decreases allograft and patient survival post-transplant. Newly developed direct acting antivirals have revolutionized the way HCV is treated. Whether patients are treated before or after kidney transplantation, the cure rates with direct acting antivirals are >90%. Great debate has formed revolving the optimal timing to treat kidney transplant candidates. On the one hand, treatment before transplantation decreases early post-transplant complications related to HCV. On the other, postponing treatment until after transplantation opens the possibility of transplanting a kidney from a HCV positive donor, which is associated with shorter waiting time and improved organ utilization by expanding the organ donor pool. Most patients living in an area where waiting time is reduced by accepting an HCV positive kidney would benefit by the strategy of treatment post-transplantation, but this decision needs to be individualized in a patient-by-patient basis given that there are special circumstances (i.e., severe HCV-related extrahepatic manifestations, availability of live donors, etc.) in which treatment before transplant might be preferred.

Abstract
A substantial body of literature has unequivocally established that prevalent hepatitis C virus infection in chronic kidney disease (CKD), end stage renal disease (ESRD) and kidney transplant recipients is associated with a negative impact on patient survival. As a consequence of remarkable work that explained the details of the hepatitis C virus (HCV) genome, a class of drugs referred to as the direct-acting antiviral (DAA) agents were developed that targeted specific key sites in viral replication. Large clinical trials in the HCV-infected general population followed soon after that demonstrated cure rates exceeding 95%. Treatment paradigms have been further refined and expanded to populations of patients that were initially excluded from the large pivotal trials. This includes the CKD and ESRD patients for whom there are now safe and effective DAAs available as well. In this context, the focus of decision making has shifted from initially demonstrating safety and efficacy to now identifying which patient should receive therapy and at what point in their CKD/ESRD journey. The specific issue of timing of treatment is particularly relevant to the HCV-infected ESRD patient who is being considered for kidney transplantation. The option of treating with DAAs prior to the transplant or alternatively delaying therapy and treating in the posttransplant period will be influenced by several factors, including patient preference, the extent of liver injury, the availability of a living or deceased donor, and more recently the option of transplanting a kidney from HCV-positive donor. The latter has been associated with the advantage of shortened waiting times and expansion of the organ donor pool. The optimal timing and choice of therapy will be the result of a decision that has been individualized for each patient as a consequence of a process of clear communication involving the patient, primary care physician, nephrologist, gastroenterologist (GI)/hepatologist, and local transplant center.

[PMID: 31179323 PMCID: PMC6507153 DOI: 10.1155/2019/4674560] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 01/14/2019] [Accepted: 03/26/2019] [Indexed: 02/07/2023]
Abstract
Hepatitis C virus (HCV) infection unfavorably affects the survival of both renal patients undergoing hemodialysis and renal transplant recipients. In this subset of patients, the effectiveness and safety of different combinations of interferon-free direct-acting antiviral agents (DAAs) have been analyzed in several small studies. Despite fragmentary, the available data demonstrate that DAA treatment is safe and effective in eradicating HCV infection, with a sustained virologic response (SVR) rates nearly 95% and without an increased risk of allograft rejection. This review article analyzes the results of most published studies on this topic to favor more in-depth knowledge of the readers on the subject. We suggest, however, perseverating in this update as the optimal DAA regimen may not be proposed yet, because of the expected arrival of newer DAAs and of the lack of data from large multicenter randomized controlled trials.

Abstract
An in-depth understanding of viral hepatitis is important to the care of patients with end-stage renal disease undergoing hemodialysis. Both hepatitis B and C viruses are acquired through hematogenous spread and can lead to horizontal transmission. Concurrent hepatic and renal injuries have ominous outcomes with significant morbidity. Hepatitis B incidence has decreased through practices including vaccination of nonimmune individuals and isolation of patients with the disease. The pathogenesis of hepatitis B leads to various symptoms and serologic changes with unique temporal associations dictating an acute or chronic presentation. Chronic hepatitis B develops when there is persistence of surface antigen for more than 6 months. Occult hepatitis B is an enigmatic form of the chronic disease where viral DNA is present despite the patient remaining seronegative. Nucleoside analogs are used as a treatment for individuals with hepatitis B who have comorbid CKD; however, the mainstay of infection control relies on immunization. Hepatitis C, an RNA virus, has increased in prevalence. Strict universal precautions with sound infection-control practices are important to prevent seroconversion. Recent therapeutic advances involving the development of direct-acting antiviral agents have broadened treatment options for patients with renal impairment and hepatitis C, offering the potential for a definitive cure. Controversy on the timeliness of treatment for transplant options has also risen with the advent of these newer therapies. We review the epidemiology, pathophysiology, and updates in treatment of these viral entities as they relate to the hemodialysis population.

Use of Organs From Hepatitis C Virus-Positive Donors for Uninfected Recipients: A Potential Cost-Effective Approach to Save Lives? Transplantation 2018; 102:664-672.

Abstract
BACKGROUND Organs from hepatitis C virus (HCV) seropositive (HCVpos) individuals are seldom used for transplantation because of the risk of disease transmission. Because transmitted HCV is now amenable to effective treatment, we estimated the potential impact of using HCVpos deceased donor organs for transplantation. METHODS The Potential Donor Audit of patients (<80 years) dying in UK critical care units and the UK Transplant Registry was searched to identify HCVpos potential and proceeding deceased donors. Donor organ quality was assessed using validated donor organ quality indices. Cost analysis was performed by comparing the cumulative cost of direct-acting antivirals with hemodialysis and renal transplantation. RESULTS Between 2009 and 2016, 120 patients identified from the Potential Donor Audit were not considered as potential donors because of the presence of HCV. Between 2000 and 2015, 244 HCVpos potential deceased donors were identified from the UK Transplant Registry, and 76 (31%) proceeded to donation, resulting in 63 liver, 27 kidney, and 2 heart transplants. Recipient and graft survival was not adversely impacted by donor HCVpos status. Most (69%) offered organs were declined because of positive virology although their quality was similar to that of other transplanted organs. The additional costs of treating recipients exposed to HCV by receiving a HCVpos kidney was cost-neutral with dialysis 5 years from transplantation. CONCLUSIONS HCVpos donors represent a potential source of organs for HCV seronegative recipients as many good quality HCVpos donor organs are not currently used for transplantation. This change in practice may increase access to transplantation without having an adverse effect on transplant outcome.

Abstract
The identification of hepatitis C virus (HCV) occurred in 1989, and soon thereafter, it was recognized that there was a higher prevalence of anti-HCV seropositivity in patients with end-stage renal disease (ESRD) when compared to the general population. Multiple extrahepatic manifestations have been associated with HCV infection in patients with ESRD; these include an increased prevalence and risk of cardiovascular complications, insulin resistance, diabetes mellitus, and lymphoproliferative disorders. Infection with HCV has also been associated with an increased relative risk of mortality in the ESRD patient when contrasted to those patients without infection. The availability of second-generation direct-acting antiviral agents has revolutionized the treatment of HCV in both the general population as well as those patients with advanced chronic kidney disease and receiving dialysis. These new treatment protocols are very well tolerated with limited side effects and manageable drug-drug interactions while achieving remarkable sustained viral response rates. It is important that nephrologists become familiar with the differing strategies available for HCV-infected ESRD patients so that the appropriate decision of when and who to treat can be made for each patient.

Abstract
AIMS The data regarding the treatment of chronic hepatitis C (CHC) in renal transplant recipients is lacking from the Asia-Pacific region. The aim of the present study was to assess the safety and efficacy of directly acting antivirals (DAAs) in the treatment of CHC infection in renal transplant recipients. METHODS A total of 47 CHC infected renal transplant recipients were enrolled in this real life observational cohort analysis between March 2015 and September 2016. Presence of hepatic fibrosis/cirrhosis was assessed on transient elastography (Fibroscan). Fourteen patients were treated with Sofosbuvir and Ribavirin for 24 weeks. Twenty-two patients received Sofosbuvir and Ledipasvir and 12 patients received Sofosbuvir and Daclatasvir with (n = 3) or without (n = 31) Ribavirin for 12 or 24 weeks depending on genotype and underlying cirrhosis. Data were analyzed for safety and treatment efficacy [sustained virological response at 12 weeks (SVR12)]. RESULTS The median baseline HCV RNA concentration in the whole group was 7.38 × 106 IU/mL (1.23 × 104 -6.36 × 107 ). The SVR12 rates were 100% in all groups except in the Sofosbuvir and Ribavirin group (86%). Transient Elastography revealed minimal or no fibrosis (F0-F1) in 31 (65.96%) patients, moderate fibrosis (F2) in 11 (23.4%) patients and cirrhosis in five (10.64%) patients. The only serious adverse effect was anaemia observed in eight (57%) patients in the Sofosbuvir and Ribavirin group. CONCLUSION DAAs including Sofosbuvir, Daclatasvir and Ledipasvir with or without ribavirin are safe and effective for the treatment of chronic hepatitis C in renal transplant recipients.

Abstract
Kidneys from deceased donors who are hepatitis C virus (HCV) nucleic acid test positive are infrequently used for transplantation in HCV-negative patients due to concerns about disease transmission. With the development of direct-acting antivirals (DAAs) for HCV, there is now potential to use these kidneys in HCV-negative candidates. However, the high cost of DAAs poses a challenge to adoption of this strategy. We created a Markov model to examine the cost-effectiveness of using deceased donors infected with HCV for kidney transplantation in uninfected waitlist candidates. In the primary analysis, this strategy was cost saving and improved health outcomes compared to remaining on the waitlist for an additional 2 or more years to receive a HCV-negative transplant. The strategy was also cost-effective with an incremental cost-effectiveness ratio of $56 018 per quality-adjusted life year (QALY) from the payer perspective, and $4647 per QALY from the societal perspective, compared to remaining on the waitlist for 1 additional year. The results were consistent in 1-way and probabilistic sensitivity analyses. We conclude that the use of kidneys from deceased donors with HCV infection is likely to lead to improved clinical outcomes at reduced cost for HCV-negative transplant candidates.

Abstract
Pilot studies suggest that transplanting hepatitis C virus (HCV)-positive donor (D+) kidneys into HCV-negative renal transplant (RT) recipients (R-), then treating HCV with direct-acting antivirals (DAA) is clinically feasible. To determine whether this is a cost-effective approach, a decision tree model was developed to analyze costs and effectiveness over a 5-year time frame between 2 choices: RT using a D+/R- strategy compared to continuing dialysis and waiting for a HCV-negative donor (D-/R-). The strategy of accepting a HCV+ organ then treating HCV was slightly more effective and substantially less expensive and resulted in an expected 4.8 years of life (YOL) with a cost of ≈$138 000 compared to an expected 4.7 YOL with a cost of ≈$329 000 for the D-/R- strategy. The D+/R- strategy remained dominant after sensitivity analyses including the difference in RT death probabilities or acute rejection probabilities between using D+ vs D- kidney; time that D-/R- patients waited for RT; dialysis death probabilities while waitlisted for RT in the D-/R- strategy; DAA therapy expected cure rate; costs of transplant, immunosuppressives, DAA therapy, dialysis, or acute rejection. The D+/R- strategy followed by treatment with DAA is less costly and slightly more effective compared to the D-/R- strategy.

Abstract
In recent years, the opioid epidemic and new hepatitis C virus (HCV) treatments have changed the landscape of organ procurement and allocation. We studied national trends in solid organ transplantation (2000⁻2016), focusing on graft utilization from HCV seropositive deceased donors in the pre-2014 (2000⁻2013) versus current (2014⁻2016) eras with a retrospective analysis of the United Network for Organ Sharing database. During the study period, HCV seropositive donors increased from 181 to 661 donors/year. The rate of HCV seropositive donor transplants doubled from 2014 to 2016. Heart and lung transplantation data were too few to analyze. A higher number of HCV seropositive livers were transplanted into HCV seropositive recipients during the current era: 374 versus 124 liver transplants/year. Utilization rates for liver transplantation reached parity between HCV seropositive and non-HCV donors. While the number of HCV seropositive kidneys transplanted to HCV seropositive recipients increased from 165.4 to 334.7 kidneys/year from the pre-2014 era to the current era, utilization rates for kidneys remained lower in HCV seropositive than in non-HCV donors. In conclusion, relative underutilization of kidneys from HCV seropositive versus non-HCV donors has persisted, in contrast to trends in liver transplantation.

Abstract
BACKGROUND Kidney transplantation from hepatitis C seropositive (HCV+) donors may benefit hepatitis C RNA-positive (RNA+) candidates, but it is unclear how the willingness to be listed for and accept such kidneys affects waitlist and transplant outcomes. METHODS In a single-center retrospective analysis, HCV+ transplant candidates (N = 169) listed from March 2004 to February 2015 were evaluated. All RNA+ candidates were offered the option to be listed for HCV+ donors. RNA- candidates were listed only for HCV- donors. RESULTS Fifty-seven patients (51% of all RNA+ transplant candidates) willing to accept HCV+ donors were listed for both HCV+ and HCV- donor kidneys. During 6-year follow up, 43 (75%) of 57 patients accepting HCV+ versus 19 (35%) of 55 patients not accepting HCV+ received a deceased donor kidney transplant (P < 0.0001). Multivariable analysis demonstrated that willingness to be listed for and accept HCV+ kidneys was associated with receiving deceased donor kidney transplant (P = 0.0016). Fewer patients accepting HCV+ donors (7 [12%] vs 16 [29%]) were removed from the list due to death or deteriorated medical condition (P = 0.0117). Posttransplant patient and graft survival rates were not significantly different. Overall patient survival since the listing (combined waitlist and posttransplant survival) was similar among the groups. CONCLUSIONS HCV RNA+ candidates had better access to transplantation and similar overall survival before the era of widespread use of direct-acting anti-HCV agents.

Abstract
Hepatitis C virus infection (HCV) is a common comorbidity in patients who have undergone kidney transplantation and is associated with increased morbidity and mortality compared with recipients who do not have chronic HCV infection. Because interferon-α-based therapies can precipitate acute rejection, they are relatively contraindicated after kidney transplantation. Thus, the majority of kidney transplant recipients with HCV remain untreated. There are now all-oral, interferon-free direct-acting antiviral therapies for HCV infection that are extremely effective and well tolerated in the general population. Recent reports in the literature demonstrate that direct-acting antiviral therapies effectively cured HCV in 406 of 418 kidney transplant recipients (97%); the majority were treated with sofosbuvir-based regimens. Smaller numbers of kidney transplant recipients have been treated with paritaprevir-ritonavir, ombitasvir and dasabuvir, elbasvir-grazoprevir, or glecaprevir-pibrentasvir with excellent success. Direct-acting antiviral therapies were well tolerated and did not increase the rate of acute rejection. The latest advances include approval of regimens that can treat patients with advanced allograft dysfunction (eGFR < 30 ml/min per 1.73 m2) and "pan-genotypic" regimens that have activity against all 6 major genotypes of HCV. This review summarizes what is known about the epidemiology of HCV infection in kidney transplant recipients, and presents the landscape of direct-acting antiviral therapies and areas in need of further investigation.

Abstract
Hepatitis C virus (HCV) infection, a major cause of end-stage liver disease, is a common comorbidity in patients on dialysis and causes increased morbidity and mortality. Historically HCV has been extremely difficult to cure with interferon and ribavirin-based therapies, which are also associated with significant side effects, and few dialysis patients ever received HCV treatment. However, in the last 4 years, interferon-free direct-acting antiviral therapies have been approved, and several combinations have been studied in dialysis patients. A recently approved, pan-genotypic, direct-acting antiviral regimen, glecaprevir and pibrentasvir, may simplify prescribing. The simplicity of these new therapies, with few side effects, makes it possible for nephrologists to treat HCV infection in their patients on dialysis. We review the workflow and motivation behind nephrology-led management of HCV infection. We highlight the importance of identifying which patients need referral to a hepatologist or HCV specialist prior to treatment and which can be managed by their nephrologist. Nephrologist involvement would lead to improved access to treatment and ensure that appropriate patients are referred for HCV treatment. In this paper, we review the background of HCV infection, its effect on dialysis patients, and impact on kidney transplantation. In addition, we outline the therapy options for each genotype of HCV, and we discuss the benefits and barriers to nephrology-led HCV treatment.
