Abstract
Hepatitis C is a global health concern, with important implications in chronic kidney disease (CKD) due to its increased prevalence in this population. Patients with advanced CKD have until recently been excluded from the pivotal direct acting anti-viral (DAA) trials, which have demonstrated high virological cure numbers. Sofosbuvir-free DAAs dasabuvir, ombitasvir/paritaprevir/ritonavir with or without ribavirin, and elbasvir/grazoprevir are well-tolerated in patients with genotype 1 and 4 CHC with CKD 4 or 5 (including HD), with virologic cure rates of above 90%, in both single-arm and placebo-controlled studies. More recently a pangenotypic approach using glecaprevir and pibrentasvir has also been shown to be highly effective in CKD 4-5. With increasingly successful treatment options with minimal side-effects most hepatitis C virus (HCV)-infected patients with CKD and ESRD can be cured. Outstanding issues to be considered is how to raise the awareness of the availability of safe DAAs and excellent outcomes in CKD, and moreover to define optimal timing of treatment and address the question of HCV eradication in all stages of CKD including the dialysis population.

Abstract
Hepatitis C virus (HCV) infection is now considered a systemic disease due to the occurrence of extra-hepatic manifestations. Among these, the renal involvement is frequent. HCV infection, in fact, is strongly associated with proteinuria and chronic kidney disease (CKD) and negatively affects the prognosis of renal patients. In the last few years, availability of more specific and effective drugs against HCV has dramatically changed the clinical course of this disease. These drugs may provide further advantages in the CKD population as a whole by reducing progression of renal disease, mortality rate and by increasing the survival of graft in renal transplant recipients. The strict pathogenetic and prognostic link between HCV infection and CKD requires an ongoing relationship among the healthcare professionals involved in the treatment of both HCV infection and CKD. Therefore, Scientific Societies involved in the care of this high-risk population in Italy have organized a joint expert panel. The aim of the panel is to produce a position statement that can be used in daily clinical practice for the management of HCV infected patients across the whole spectrum of renal disease, from the conservative phase to renal replacement treatments (dialysis and transplantation). Sharing specific evidence-based expertise of different professional healthcare is the first step to obtain a common ground of knowledge on which to instate a model for multidisciplinary management of this high-risk population. Statements cover seven areas including epidemiology of CKD, HCV-induced glomerular damage, HCV-related renal risk, staging of liver disease in patients with CKD, prevention of transmission of HCV in hemodialysis units, treatment of HCV infection and management of HCV in kidney transplantation.

Abstract
Background Direct-acting antiviral agents (DAAs) permit the use of interferon (IFN)-free regimens to treat hepatitis C (HCV) in patients with chronic kidney disease (CKD) on hemo-dialysis (HD) or renal transplant (RTx) recipients, with excellent response rates and safety. However, the occurrence of basal or therapy-induced resistance-associated substitutions (RASs) to DAAs can result in treatment failure. The aim of this study was to estimate the prevalence of RASs to NS3A, NS5A and NS5B inhibitors, and particularly the Q80K polymorphism, in CKD patients on HD and RTx recipients infected with HCV. Patients and methods HD and RTx patients infected with HCV-genotype 1 (GT1) were subjected to sequencing of the NS3, NS5A and NS5B regions. Results Direct sequencing of NS3 protease, NS5A and NS5B was performed in 76 patients (HD, n=37; RTx, n=39). The overall prevalence of RASs was 38.2%, but only 5.3% of the patients had mutations in more than one region. Substitutions were detected in NS3A (17.8%), NS5A (21.9%) and NS5B (8.4%). Q80K was detected in 1.5 % of the patients. Highly inhibitory RASs were uncommon (L31M, 2.6%; L159F+C316N, 2.6%). RASs were more prevalent in HCV-GT1a (42.9%) than in HCV-GT1b (32.4%), P=0.35. RASs were detected in 52.4% of treatment-naive patients and 27.8% of peg-IFN/ribavirin-experienced patients (P=0.12). The presence of RASs was associated with time of RTx (P=0.01). Conclusion The Q80K polymorphism was uncommon in our sample of HD and RTx patients. Despite the high prevalence of naturally occurring RASs, most of the substitutions detected were associated with a low level of resistance to DAAs.

Abstract
Well-tolerated, ribavirin-free, pangenotypic hepatitis C virus (HCV) treatments for transplant recipients remain a high priority. Once-daily glecaprevir/pibrentasvir demonstrates high rates of sustained virologic response at 12 weeks posttreatment (SVR12) across all major HCV genotypes (GTs). This trial evaluated the safety and efficacy of glecaprevir/pibrentasvir for patients with chronic HCV GT1-6 infection who had received a liver or kidney transplant. MAGELLAN-2 was a phase 3, open-label trial conducted in patients who were ≥3 months posttransplant. Patients without cirrhosis who were HCV treatment-naive (GT1-6) or treatment-experienced (GT1, 2, 4-6; with interferon-based therapy with or without sofosbuvir, or sofosbuvir plus ribavirin) received glecaprevir/pibrentasvir (300/120 mg) once daily for 12 weeks. The primary endpoint compared the percentage of patients receiving glecaprevir/pibrentasvir with SVR12 to a historic SVR12 rate based on the standard of care. Safety of glecaprevir/pibrentasvir was assessed. In total, 80 liver transplant and 20 kidney transplant patients participated in the trial. Most patients had no or minimal fibrosis (80% had fibrosis scores F0-F1) and were infected with HCV GT1 (57%) or GT3 (24%). The overall SVR12 was 98% (n/N = 98/100; 95% confidence interval, 95.3%-100%), which exceeded the prespecified historic standard-of-care SVR12 threshold of 94%. One patient experienced virologic failure. One patient discontinued because of an adverse event considered to be unrelated to treatment; this patient achieved SVR12. Adverse events were mostly mild in severity, and laboratory abnormalities were infrequent. CONCLUSION Once-daily glecaprevir/pibrentasvir for 12 weeks is a well-tolerated and efficacious, ribavirin-free treatment for patients with chronic HCV GT1-6 infection who have received a liver or kidney transplant.

Abstract
Kidney transplant from donors with hepatitis C virus (HCV) antibody has been limited to HCV viremic recipients only, due to concern of the HCV transmission. However, the new antiviral medications provide an opportunity to expand the utilization of these donors. To study the risk of HCV transmission in kidney transplantation, we used discarded donor kidneys and determined HCV RNA levels by quantitative real-time PCR in bilateral (right and left) kidney biopsies and plasma from 14 HCV antibody-positive donors (sensitivity: 15 international unit (IU)/mL plasma; 1.8 IU/50 nL kidney). In three NAT-negative donors, HCV RNA was negative in plasma and kidney. In all 11 NAT-positive donors, HCV RNA was positive in plasma (range: 5807-19 134 177 IU/mL) but negative in six kidneys from four donors with plasma HCV RNA <1.5 million IU/μL. HCV RNA correlated between right and left kidneys (P = 0.75) and between kidney and plasma (r = 0.86). When normalized by volume, HCV RNA median (range) was 49 (0-957) IU/50 nL plasma and 1.0 (0-103) IU/50 nL kidney, significantly lower in kidney (P = 0.005) than in plasma (14-fold). Plasma HCV RNA can be used to predict the kidney HCV load. Future studies are needed if plasma/kidney HCV levels can be used to stratify donors for transmission risk and recipients for post-transplant management in extended utilization of HCV antibody-positive donors.

Eradication of HCV in Renal Transplant Recipients and Its Effects on Quality of Life. BIOMED RESEARCH INTERNATIONAL 2018; 2018:8953581.

Abstract
Background The use of direct antiviral agents (DAA) has radically modified the course of HCV hepatitis in renal patients. Aim of this study was to assess the effects of HCV eradication on quality of life (QOL) in renal transplant recipients (RTR), measured by CLDQ and SF-36. Methods Sixteen RTR with well preserved GFR (mean: 60.3±19.3 ml/min) and chronic HCV infection with moderate liver stiffness (9.3±1.7 kPa) were given a sofosbuvir-based regimen for 12 weeks and had a 1 year follow-up. Results At end of treatment (EOT) a complete viral clearance was observed in all the patients, with normalization of most laboratory data and a consistent reduction in liver stiffness. All these parameters remained stable after 1 year, as well as renal function and proteinuria. Questionnaire data showed consistent amelioration in different “emotional” domains at EOT, which persisted after 1 year and were associated with a globally improved QOL, although there was no change in most of the “physical” domains in both questionnaires. One patient under ribavirin developed an acute anemia and withdrew from the study, but no further adverse episode was observed throughout the study. Conclusions Our data, while confirming the efficacy of oral DAA, show that HCV infection represents a heavy psychological burden in renal transplant recipients, greatly alleviated by viral eradication, which determines a significant improvement in QOL that represents an important outcome in management of all transplant recipients. This trial is registered with ISRCTN97560076.

Abstract
The medium-term impact on graft function and immunosuppressive drug pharmacokinetics of direct antiviral agents (DAAs) among hepatitis C virus (HCV)-infected kidney transplant (KT) recipients remain unclear. We compared pre- and post-treatment 12-month trajectories of estimated glomerular filtration rate (ΔeGFR) and 24-h proteinuria (Δ24-h proteinuria) in 49 recipients treated with DAAs (mostly sofosbuvir plus ledipasvir). Among evaluable patients, 66.7% and 100.0% had undetectable viral load by week 4 and end of therapy (EoT). The sustained virologic response rate at 12 weeks was 95.8%. Overall, 80.6% of patients receiving tacrolimus required dose escalation while on DAA-based therapy (median increase of 66.7%) to maintain target levels. Tacrolimus levels resulted to be higher at 12 months compared to EoT (7.8 ± 2.1 vs. 6.7 ± 2.0 ng/ml; P-value = 0.002). No changes in graft function during the course of therapy were observed. However, eGFR significantly decreased (P-value <0.001) throughout the first 12 months after EoT. Median ΔeGFR and Δ24-h over pre- and post-treatment periods were 3.9% and -6.1% (P-value = 0.002) and -5.3% and 26.2% (P-value = 0.057). Caution should be exercised when adjusting immunosuppression in HCV-infected KT recipients upon initiation of DAAs, followed by mid-term monitoring of immunosuppressive drug levels and graft function.

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 (HCV) infection in chronic kidney disease (CKD) is associated with increased liver-related morbidity and mortality rates, accelerated progression to end-stage renal disease, and risk of cardiovascular events. CKD patients with HCV infection require antiviral therapy. Pegylated interferon (peg-IFN) plus ribavirin was the standard of care for HCV-infected CKD patients before the introduction of first-generation direct-acting antiviral (DAA) oral anti-HCV agents. Peg-IFN-based treatment has a low virologic response rate and poor compliance, resulting in a high dropout rate. Recently, several clinical trials of all-DAA combination regimens have reported excellent antiviral efficacy and few adverse drug reactions in HCV-infected patients with CKD. These positive results have revolutionized the treatment of chronic HCV infection in this population. In this review, we address the impact of chronic HCV infection in CKD patients, and discuss their management using next-generation DAAs.

Abstract
PURPOSE OF REVIEW To highlight the changing landscape of hepatitis C virus (HCV) infection in the context of organ transplantation. This focuses on areas of controversy and future potential in the era of highly effective direct-acting antiviral (DAA) agents. RECENT FINDINGS Since the advent of safe and highly effective DAA therapy, HCV infection is now curable in virtually all cases, including organ transplant recipients. Excellent drug tolerability and safety combined with high cure rates across all organ groups means that HCV is no longer a barrier to transplantation or its outcomes. Mounting data demonstrate the safety of using organs from HCV-infected donors with subsequent treatment of HCV in the recipient and a potential to expand the donor pool. Historical data demonstrating inferior survival in transplant recipients with HCV is of limited relevance in the DAA era. Virtually all transplant recipients with HCV infection can be cured, while early data also suggest excellent outcomes in recipients of organs from HCV viremic donors. The optimal timing of HCV therapy in relation to transplantation and the optimal use of organs from HCV viremic donors remain areas of controversy and ongoing research efforts.

Higher risk of renal disease in chronic hepatitis C patients: Antiviral therapy survival benefit in patients on hemodialysis. J Hepatol 2018; 68:904-911. [PMID: 29233630 DOI: 10.1016/j.jhep.2017.12.003] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2017] [Revised: 11/08/2017] [Accepted: 12/01/2017] [Indexed: 12/24/2022]
Abstract
BACKGROUND & AIMS Several studies have shown that chronic hepatitis C (CHC) infection has a negative impact on kidney function, as well as survival, in patients with chronic kidney disease (CKD) or on hemodialysis. The aim of this nationwide registry study was to describe renal disease in Swedish patients with CHC. METHODS In the present study, patients were identified for CHC (B18.2) and CKD (N18) according to the International Classification of Diseases (ICD)-10 in the nationwide Swedish inpatient care day surgery (1997-2013) and non-primary outpatient care (2001-2013) patient registries. Hemodialysis was defined using the procedure code in the non-primary outpatient care. For each patient, up to five non-CHC diagnosed age/sex/place of residency-matched comparators were drawn from the general population at the time of diagnosis. Follow-up started at the date of CHC diagnosis and patients accrued person-time until, whichever came first, death, emigration or December 31st, 2013. RESULTS Between 2001 and 2013, 42,522 patients received a CHC diagnosis. Of these patients, 2.5% (1,077/45,222) were diagnosed with CKD during 280,123 person-years, compared with 0.7% (1,454/202,694) in the matched general population comparators (1,504,765 person-years), resulting in a standardized incidence ratio (SIR) of 4.0. There was a 3.3-7.0-fold risk of patients with CHC requiring hemodialysis. Overall, 17% of patients with CHC receiving hemodialysis were treated for CHC; 24% in the treated cohort died compared with 56% of the untreated cohort (p <0.0001), with antiviral treatment improving survival with an odds ratio of 3.901 (p = 0.001). CONCLUSIONS The results from this nationwide registry study showed that patients with CHC are at a higher risk of developing CKD. Furthermore, hepatitis C treatment seemed to improve survival for patients with CHC on hemodialysis compared with untreated patients. LAY SUMMARY Hepatitis C is an infectious disease that mainly infects the liver, but has also been shown to have negative effects on other organs. This nationwide study demonstrates an increased risk of hepatitis C patients developing reduced kidney function and the need for dialysis. The study also showed improved survival in dialysis patients who received antiviral treatment.

Abstract
BACKGROUND Since the introduction of direct antiviral agents (DAAs), morbidity of HCV has considerably decreased but still no guidelines have been formulated in renal transplant recipients (RTRs). We studied efficacy and tolerability of direct antiviral agents in RTRs. METHODS This prospective observational study was conducted at Army Hospital Research & Referral, Delhi, from June 2016 to May 2017. Forty-five HCV infected RTRs with stable graft function were included. RESULTS Median time between renal transplantation and the start of anti-HCV therapy was 36 months (1-120 months). The majority (66.7%) were infected with genotype 3. Baseline median HCV RNA level was 542648 IU/ml (1189-55028534 IU/ml). Sofosbuvir-Ribavirin combination (24 weeks) was given to 30 patients including 3 cirrhotics, Ledipasvir-Sofosbuvir combination to 8 patients, and Daclatasvir-Sofosbuvir combination to 7 patients, including 2 cirrhotics. Rapid virological response was observed in 29 patients treated with Sofosbuvir/Ribavirin, all 8 patients on Sofosbuvir/Ledipasvir, and all 7 patients on Sofosbuvir/Daclatasvir. End treatment response and sustained virological response (12 weeks) were achieved in all patients irrespective of genotype or treatment regimen. Decrease in mean HCV RNA level and transaminase level was statistically significant (p < 0.01). Ribavirin was significantly associated with anaemia (p = 0.032). CONCLUSIONS DAA regimens are well tolerated and highly efficacious. Response to DAA is good irrespective of genotype, drug combination, initial HCV RNA level, age or sex of patient, or graft age. However, Sofosbuvir/Ledipasvir and Sofosbuvir/Daclatasvir combination is preferable.

Antimicrob Agents Chemother 2018; 62:AAC.01990-17.

Abstract
Hepatitis C virus (HCV) infection is an independent risk factor for developing chronic renal impairment and end-stage renal disease. Limited treatment options are available for HCV genotype 2, 3, 5, and 6 infections in patients with an estimated glomerular filtration rate (eGFR) of <30 ml/min. Glecaprevir and pibrentasvir are active against all six major HCV genotypes, are primarily excreted in the bile, and have minimal renal elimination. Therefore, combined treatment with these direct-acting antivirals may be useful for patients with HCV infection and chronic kidney disease. A phase 1, multicenter, open-label study evaluated the effects of renal impairment on the pharmacokinetics and safety of glecaprevir-pibrentasvir. In substudy 1, 38 subjects with stage 2 to 5 chronic kidney disease who were not on dialysis or who had normal renal function received single doses of the combination of 300 mg glecaprevir and 120 mg pibrentasvir. In substudy 2, 8 subjects requiring hemodialysis received single doses of the combination of 300 mg glecaprevir and 120 mg pibrentasvir under dialysis and nondialysis conditions. Regression analyses demonstrated increased glecaprevir and pibrentasvir plasma exposures, as determined by the area under the curve, with decreasing renal function, up to 56% and 46%, respectively, in subjects with an eGFR of <15 ml/min/1.73 m2 In dialysis-dependent subjects, glecaprevir and pibrentasvir exposures were similar (≤18% difference) when study drugs were administered before hemodialysis or on a nondialysis day. Adverse events were mostly mild, with the most common being self-limited fatigue (3 subjects). The study findings support the clinical evaluation of glecaprevir-pibrentasvir without dose adjustment in HCV-infected subjects with renal impairment. (This study has been registered at ClinicalTrials.gov under registration number NCT02442258.).

Abstract
Hepatitis C virus (HCV) infection in renal allograft recipient is associated with increased morbidity and mortality. At present, only few studies related to treatment and outcomes of HCV-infected renal allograft recipients with DAAs have been published. We aimed the study to assess the efficacy and safety of sofosbuvir-based regimens in HCV-infected renal allograft recipients. We analyzed data of 22 eligible HCV-infected renal allograft recipients (14 genotype-3, 6 genotype-1, one each genotype-2 and 4) who were treated with DAAs at our institute. DAA regimen included sofosbuvir and ribavirin with or without ledipasvir or daclatasvir for 12–24 weeks. Patients were followed up for 24 weeks after completion of treatment. A rapid viral response of 91%, end of therapy response of 100%, and sustained viral response at 12 and 24 weeks of 100% with rapid normalization of liver enzymes were observed. Therapy was well tolerated except for ribavirin-related anemia. A significant decrease in tacrolimus trough levels was observed and most patients required increase in tacrolimus dose during the study. Treatment with newer DAAs is effective and safe for the treatment of HCV-infected renal allograft recipients.

Abstract
Hepatitis C virus (HCV) infection is associated with reduced patient survival following combined liver-kidney transplantation (LKT). The aim of this study was to assess the efficacy and safety of second-generation direct-acting antivirals (DAAs) in this difficult-to-treat population. The ANRS CO23 "Compassionate use of Protease Inhibitors in Viral C Liver Transplantation" (CUPILT) study is a prospective cohort including transplant recipients with recurrent HCV infection treated with DAAs. The present work focused on recipients with recurrent infection following LKT. The study population included 23 patients. All patients received at least one NS5B inhibitor (sofosbuvir) in their antiviral regimen an average of 90 months after LKT. Ninety-six percent of recipients achieved a sustained virological response (SVR) at week 12 (SVR12). In terms of tolerance, 39% of recipients presented with at least one serious adverse event. None of the patients experienced acute rejection during therapy and there were no deaths during follow-up. The glomerular filtration rate (GFR) decreased significantly from baseline to the end of therapy. However, this study did not show that the decline in GFR persisted over time or that it was directly related to DAAs. The DAA-based regimen is well tolerated with excellent results in terms of efficacy. It will become the gold standard for the treatment of recurrent HCV following LKT.

Abstract
The availability of direct-acting antiviral agents for the treatment of hepatitis C virus (HCV) infection has resulted in a profound shift in the approach to the management of this infection. These changes have affected the practice of solid organ transplantation by altering the framework by which patients with end-stage organ disease are managed and receive organ transplants. The high level of safety and efficacy of these medications in patients with chronic HCV infection provides the opportunity to explore their use in the setting of transplanting organs from HCV-viremic patients into non-HCV-viremic recipients. Because these organs are frequently discarded and typically come from younger donors, this approach has the potential to save lives on the solid organ transplant waitlist. Therefore, an urgent need exists for prospective research protocols that study the risk versus benefit of using organs for hepatitis C-infected donors. In response to this rapidly changing practice and the need for scientific study and consensus, the American Society of Transplantation convened a meeting of experts to review current data and develop the framework for the study of using HCV viremic organs in solid organ transplantation.

Abstract
OBJECTIVES Although direct-acting antiviral agents have revolutionized hepatitis C virus treatment, these novel agents are not widely available in the developing world. Further, no treatment recommendation for renal transplant recipients includes these agents. We aimed to evaluate the effectiveness of sofosbuvir and ribavirin, the only direct-acting antiviral agents available in Pakistan, in renal transplant recipients. MATERIALS AND METHODS All renal transplant recipients receiving sofosbuvir and ribavirin from August 2015 to March 2016 were enrolled in the study. Patients' demographics and baseline laboratory parameters were collected. Rapid virologic response, early virologic response, end-of-treatment response, and sustained virologic response at 12 and 24 weeks were analyzed. Statistical analyses were performed using IBM SPSS Statistics software, version 20.0. RESULTS Of the 37 renal transplant recipients, the mean age was 37.2 ± 10.7 years and the majority (33 [89.2% ]) were men. Twenty-five patients were treatment naive; of the remaining 12 patients, 10 were responders, 2 were nonresponders, and 5 were relapsers to pretransplant hepatitis C treatment. The genotype most commonly seen posttransplant was genotype 1 (56.8%). Rapid virologic response was achieved in 33 patients (89.2%). Early virologic response, end-oftreatment response, and sustained virologic response at 12 weeks were achieved in all 37 patients (100%). Until the time of data collection, 14 patients had achieved a sustained virologic response at 24 weeks. No complications were noted during therapy. In 2 of 4 patients who developed decompensated cirrhosis, treatment led to the resolution of ascites. CONCLUSIONS Sofosbuvir and ribavirin are well tolerated and effective in renal transplant recipients for eradicating hepatitis C virus. Their effectiveness is not limited to renal transplant recipients with genotypes 1, 2, 3, and 4 but also extends to those with mixed genotype (in this study, genotypes 1 and 3).

Abstract
BACKGROUND With the development of all oral, interferon-free directly acting antiviral (DAA) medications, treatment of hepatitis C virus (HCV) infection in renal transplant recipients is possible, but limited data exists on its safety and efficacy. METHODS We performed a retrospective cohort analysis of patients transplanted at our center with HCV who have been started on DAAs. Primary endpoints included sustained virologic response as defined as negative viral load at 12 weeks postcompletion of therapy and allograft function. RESULTS A total of 31 patients met inclusion criteria. The most commonly used regimen was sofosbuvir and ledipasvir (n = 21). Of the treated patients, 100% had undetectable viral load at the completion of therapy. Of the 31 patients treated, 30 (97%) achieved sustained virologic response. Both graft and patient survivals at most recent follow-up was 100%. There was no significant change in glomerular filtration rate (GFR) before or after therapy (64.2 ± 16.5 mL/min per body surface area before vs. 58.9 ± 17.5 mL/min per body surface area after therapy; P = 0.22); however, 3 patients now have GFR less than 20. A total of 6 (19.3%) of 31 patients had worsening proteinuria during or shortly after therapy. Patients with more than 500 mg/g of proteinuria at the start of treatment were significantly more likely to develop worsening proteinuria than those with less than 500 mg/g of proteinuria at the start of therapy (P < 0.001). Retrospective review of 20 untreated HCV patients did not demonstrate worsening allograft function and proteinuria during a median follow-up time of 1386 days (range, 332-6254). CONCLUSIONS Our preliminary data demonstrate that DAAs can be used safely and effectively in patients after kidney transplantation. Patients with proteinuria or lower GFR should be monitored more closely.

Abstract
Background NS3 protease inhibitors (PIs) were the first direct antiviral agents used for the treatment of hepatitis C virus. The combination of second-wave PIs with other direct antiviral agents enabled the use of interferon-free regimens for chronic kidney disease patients on dialysis and renal transplant (RTx) recipients, populations in which the use of interferon and ribavirin is limited. However, the occurrence of PI resistance-associated variants (RAVs), both baseline and induced by therapy, has resulted in the failure of many treatment strategies. Methods The aim of this study was to estimate the prevalence of PI RAVs and of the Q80K polymorphism in chronic kidney disease patients on hemodialysis and RTx recipients. Direct sequencing of the NS3 protease was performed in 67 patients (32 hemodialysis and 35 RTx).Results RAVs to PIs were detected in 18% of the patients: V55A (9%), V36L (1.5%), T54S (1.5%), S122N (1.5%), I170L (1.5%), and M175L (1.5%). Only 1.5% of the patients carried the Q80K polymorphism. The frequency of these mutations was more than two times higher in patients infected with GT1a (25%) than GT1b (9.7%) (P=0.1). The mutations were detected in 20% of treatment-naive patients and in 15.6% of peginterferon/ribavirin-experienced patients (P=0.64). Furthermore, no mutation that would confer high resistance to PIs was detected.Conclusion The Q80K polymorphism was rare in the population studied. The occurrence of RAVs was common, with predominance in GT1a. However, the variants observed were those associated with a low level of resistance to PIs, facilitating the use of these drugs in this special group of patients.

Abstract
Hepatitis C (HC) is a very relevant negative prognosis factor for graft and transplant recipient survival. New direct-acting antivirals (DAAs) allow us to solve this problem in an effective way. It is crucial to understand their real impact in our daily practice. We analyzed treatment results with DAA, free of interferon, in kidney transplant recipients (KTRs) from 15 Spanish hospitals (Grupo Español de Actualización en Trasplante), regarding effectiveness, tolerance, and impact on immunosuppression, renal function-proteinuria, and diabetes. One hundred nineteen KTRs were included (9 combined liver-kidney transplants). The main DAA used was sofobusvir (91%) combined with ledipasvir (55%), simeprevir (14%), or daclatasvir (13%); in 9 cases (7%), a paritaprevir-ritonavir-ombitasvir-dasabuvir combination (3D) was used; Ribavirin was used as a coadjuvant in 18%. Side effects were limited (23.5%) and without relevance in general, except in 7 patients for whom we needed to interrupt the treatment due to neurotoxicity (1) caused by drug interaction (3D and tacrolimus) or anemia (3) by Ribavirin or others. Ninety-four patients had completed the treatment when data were analyzed: virological response was seen in 97.8% % of cases. Liver function analysis improved: 84% normal versus 21% before starting the treatment (P < .001). Renal function and proteinuria did not change. Tacrolimus level at the end of DAA-treatment was significantly lower with respect to the beginning (5.8 ± 2.1 ng/mL vs. 7.4 ± 1.8 ng/mL, P = .03), despite a slight increase in the dose (2.6 mg/d vs. 2.3 mg/d, P = .17). DAA are highly effective in the treatment of hepatitis C in KTRs with good tolerance in general, making it possible to solve the problem and have a good chance to improve the prognosis in our transplantation patients. The use of these therapies in KTRs requires special control and coordination with digestive professionals, especially if 3D or Ribavirin is used.

Abstract
The availability of direct acting antiviral agents (DAA) has transformed the treatment of hepatitis C virus (HCV) infection. The current study is a case series that reports the outcomes from a cohort of twenty-five HCV-infected ESRD patients who received a kidney from an anti-HCV-positive deceased organ donor followed by treatment with DAAs in the early post-transplant period. Time to transplantation and the efficacy of DAA therapy as measured by sustained viral response at 12 weeks were assessed. The median waiting time from original date of activation on the United Network Organ Sharing (UNOS) waiting list until transplantation was 427 days; however, the median time from entering the patient into UNetsm for a HCV-positive offer until transplantation was only 58 days. The 25 patients were started on antiviral treatment early post-transplant (median 125 days) and 24 of 25 (96%) achieved a sustained virologic response at 12 weeks. Tacrolimus dose adjustments were required during antiviral treatment in 13 patients to maintain therapeutic levels. Accepting a kidney from an anti-HCV-positive deceased donor shortened the waiting time for HCV-infected kidney transplant candidates. We recommend that kidneys from anti-HCV-positive donors should be considered for transplant into HCV-infected recipients followed by early post-transplant treatment with DAA agents.

Abstract
Patients with end-stage renal diseases on hemodialysis have a high prevalence of hepatitis C infection (HCV). In most patients, treatment for HCV is delayed until postrenal transplant. We assessed the effectiveness and tolerance of ledipasvir/sofosbuvir (LDV/SOF) in 32 postkidney transplant patients infected with HCV. The group was composed predominantly of treatment-naïve (75%) African American (68.75%) males (75%) infected with genotype 1a (62.5%). Most patients received a deceased donor kidney graft (78.1%). A 96% sustained viral response (SVR) was reported (27/28 patients). One patient relapsed. One patient with baseline graft dysfunction developed borderline rejection. No graft loss was reported. Six HIV-coinfected patients were included in our analysis. Five of these patients achieved SVR 12. There were four deaths, and one of the deaths was in the HIV group. None of the deaths were attributed to therapy. Coinfected patients tolerated therapy well with no serious adverse events. Serum creatinine remained stable at baseline, end of therapy, and last follow-up, (1.351±.50 mg/dL; 1.406±.63 mg/dL; 1.290±.39 mg/dL, respectively). In postkidney transplant patients with HCV infection with or without coinfection with HIV, a combination of LDV/SOF was well tolerated and effective.

Abstract
Hepatitis-C (HCV) infection can induce kidney injury, mostly due to formation of immune-complexes and cryoglobulins, and possibly to a direct cytopathic effect. It may cause acute kidney injury (AKI) as a part of systemic vasculitis, and augments the risk of AKI due to other etiologies. It is responsible for mesangiocapillary or membranous glomerulonephritis, and accelerates the progression of chronic kidney disease due to other causes. HCV infection increases cardiovascular and liver-related mortality in patients on regular dialysis. HCV-infected patients are at increased risk of acute post-transplant complications. Long-term graft survival is compromised by recurrent or de novo glomerulonephritis, or chronic transplant glomerulopathy. Patient survival is challenged by increased incidence of diabetes, sepsis, post-transplant lymphoproliferative disease, and liver failure. Effective and safe directly acting antiviral agents (DAAs) are currently available for treatment at different stages of kidney disease. However, the relative shortage of DAAs in countries where HCV is highly endemic imposes a need for treatment-prioritization, for which a scoring system is proposed in this review. It is concluded that the thoughtful use of DAAs, will result in a significant change in the epidemiology and clinical profiles of kidney disease, as well as improvement of dialysis and transplant outcomes, in endemic areas.

Abstract
OBJECTIVES The clinical effects of hepatitis C virus infection acquired after transplant have not been thoroughly studied. We aimed to study hepatitis C virus-related morbidity and mortality with de novo hepatitis C virus infection after renal transplant. MATERIALS AND METHODS Data from mortality files were retrospectively collected from January 2011 to January 2015. Patients were divided into 2 groups: hepatitis C virus positive (group A) and hepatitis C virus negative (group B). RESULTS Eighty-one patients were included, with median duration of survival of 39 months after transplant. In group A (32 patients), 78.1% of patients were males, with mean age of 36.83 ± 9.15 years. The mean survival duration was better in group A than in group B (67.59 ± 67.1 vs 58.10 ± 59.6 mo; P = .58). Acute cellular rejection was 25% in group A versus 20.4% in group B, whereas chronic allograft nephropathy was 20.4% for group A versus 18.4% for group B. Hepatitis C virus-related death was observed in 7 patients (21.9%). Infection was the main cause of death, with 40.6% of patients in group A versus 53% of patients in group B. On multivariate analyses, better patient survival was associated with greater interval of acquiring HCV after transplant (P = .038). CONCLUSIONS HCV infection acquired after renal transplant is not associated with increased HCV-related mortality, and prognosis is related to the time interval of acquiring infection after transplant.

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 (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.

Efficacy and Safety of Direct Acting Antivirals in Kidney Transplant Recipients with Chronic Hepatitis C Virus Infection. PLoS One 2016; 11:e0158431. [PMID: 27415632 PMCID: PMC4945034 DOI: 10.1371/journal.pone.0158431] [Citation(s) in RCA: 76] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2016] [Accepted: 06/15/2016] [Indexed: 02/06/2023] Open
Abstract
The prevalence of Hepatitis C Virus (HCV) infection is significantly higher in patients with end-stage renal disease compared to the general population and poses important clinical challenges in patients who undergo kidney transplantation. Historically, interferon-based treatment options have been limited by low rates of efficacy and significant side effects, including risk of precipitating rejection. Limited data exist on the use of all-oral, interferon-free direct-acting antiviral (DAA) therapies in kidney transplant recipients. In this study, we performed a retrospective chart review with prospective clinical follow-up of post-kidney transplant patients treated with DAA therapies at three major hospitals in Boston, MA. A total of 24 kidney recipients with HCV infection received all-oral DAA therapy post-transplant. Patients were predominantly male (79%) with a median age of 60 years (range 34–70 years), median creatinine of 1.2 mg/dL (0.66–1.76), and 42% had advanced fibrosis or cirrhosis. The majority had HCV genotype 1a infection (58%). All patients received full-dose sofosbuvir; it was paired with simeprevir (9 patients without and 3 patients with ribavirin), ledipasvir (7 patients without and 1 patient with ribavirin) or ribavirin alone (4 patients). The overall sustained virologic response (SVR12) was 91% (21 out of 23 patients). One patient achieved SVR4 but demised prior to SVR12 check point due to treatment unrelated cause. Two treatment failures were successfully retreated with alternative DAA regimens and achieved SVR. Both initials failures occurred in patients with advanced fibrosis or cirrhosis, with genotype 1a infection, and prior HCV treatment failure. Adverse events were reported in 11 patients (46%) and were managed clinically without discontinuation of therapy. Calcineurin inhibitor trough levels did not significantly change during therapy. In this multi-center series of patients, all-oral DAA therapy appears to be safe and effective in post-kidney transplant patients with chronic HCV infection.

Abstract
BACKGROUND We assessed the effect of hepatitis C seropositivity on the percentage of various T-cells in living donor renal transplant recipients (LDRTRs) and their association with intercurrent infections post renal transplantation (post-Tx). METHODS One hundred and thirty-three matching LDRTRs [A (seronegative) (68 patients) and B (seropositive) (65 patients) by ELISA] were studied prospectively 10 days, 6 months and 12 months post-Tx for intercurrent infections, acute rejection and T-cell% by flow cytometry. RESULTS CD4(+), CD8(+), CD4/CD8 were significantly higher 10 days post-Tx in Group B compared to Group A, p < 0.001. A significant increase in CD8% was seen 6-month post-Tx among Group B compared to Group A. No difference was detected between groups in (CD4(+), CD8(+), CD4/CD8, CD3-CD16/65(+)%), rate and severity of intercurrent infection, rate of acute rejection, 12 months post-Tx. A significantly higher rate of severe infections particularly urinary tract infections (UTI) was noted in Group B compared to Group A the first 3 months post-Tx particularly in those who received the combination of antithymocyte globulin (ATG) or basiliximab, tacrolimus, steroids, mycophenolate mofetil (MMF). CD4(+)% correlated negatively with intercurrent infections in Group B 6 months post-Tx. CONCLUSION HCV(+) patients are more prone to intercurrent infections the first 3 months post-Tx. Infection rate correlates positively with pre-transplant HCV seropositivity and immunosuppressive regimen.

Abstract
Kidney transplantation from hepatitis C virus (HCV)-positive donors to HCV-positive recipients has always been controversial regarding the safety and the outcomes. In the posttransplant period, treatment of hepatitis C with interferon-based regimens could lead to serious side effects. A patient with chronic hepatitis C and nephropathy, on dialysis, underwent renal transplantation from an HCV-positive donor and received direct-acting antiviral (DAA) drugs thereafter. His renal and liver functions, as well as the hepatitis C viral load, were evaluated at predetermined intervals throughout and after his treatment. Patient's viral load was undetectable 4, 12, and 24 weeks after initiation of his treatment. Renal and liver functions were maintained at baseline, with no evidence of transplant rejection. Our clinical case is one of the few examples in the medical literature that shows successful suppression of replication of HCV in an HCV-infected kidney transplant candidate who received within 2 months of listing a deceased donor kidney transplant from an HCV-infected donor. The recipient was treated with DAAs, and this case illustrates potential safety and efficacy of this approach.

Abstract
BACKGROUND & AIMS Treating chronic hepatitis C (CHC) in patients with end-stage renal disease (ESRD) has suboptimal tolerability and cure rates. Safety and efficacy of sofosbuvir plus simeprevir regimen in CHC-infected patients with ESRD on haemodialysis (HD) or glomerular filtration rate (GFR) <30 ml/min is unknown. We evaluated the safety and efficacy of sofosbuvir and simeprevir in this special patient population. METHODS All (n = 17) patients in the analysis had ESRD on HD or GFR <30 ml/min. All received sofosbuvir 400 mg daily and simeprevir 150 mg daily, without ribavirin for 12 weeks. Safety and efficacy data were collected; including SVR4 and SVR12 data for all patients after completing therapy. RESULTS In this 17 patient cohort, eight (47%) were cirrhotic, four (24%) had stage three liver fibrosis and 13 (76%) were genotype 1A. All 17 have completed 12 weeks of therapy. Treatment was overall well tolerated with no treatment discontinuations reported. Four (24%) patients reported mild adverse events (AE). These AEs were insomnia (n = 2), headache (n = 1), nausea (n = 1) and worsening anaemia requiring blood transfusion (n = 1). All 17 patients reached post-treatment week-12 follow-up, and achieved SVR12 or virological cure (100% SVR12). CONCLUSIONS Daily, full dose of sofosbuvir plus simeprevir for 12 weeks of therapy appears to be well tolerated in patients with ESRD on HD or GFR <30 ml/min. Most common AEs resembled those of healthier CHC patients without significant renal impairment. The cure rates obtained in this cohort treated with sofosbuvir and simeprevir are dramatically superior to any previous treatment regimen studied & published in this special patient population.

Abstract
India contributes significantly to the global burden of HCV. While the nucleoside NS5B inhibitor sofosbuvir became available in the Indian market in March 2015, the other directly acting agents (DAAs), Ledipasvir and Daclatasvir, have only recently become available in the India. The introduction of these DAA in India at a relatively affordable price has led to great optimism about prospects of cure for these patients as not only will they provide higher efficacy, but combination DAAs as all-oral regimen will result in lower side effects than were seen with pegylated interferon alfa and ribavirin therapy. Availability of these newer DAAs has necessitated revision of INASL guidelines for the treatment of HCV published in 2015. Current considerations for the treatment of HCV in India include the poorer response of genotype 3, nonavailability of many of the DAAs recommended by other guidelines and the cost of therapy. The availability of combination DAA therapy has simplified therapy of HCV with decreased reliance of evaluation for monitoring viral kinetics or drug related side effects.

Abstract
Recent studies including the current article by Sawinski et al. demonstrate that hepatitis C virus (HCV) infection is associated with worse outcomes in kidney transplant recipients with and without HIV infection. We comment on the significance of these findings in the context of newer options for the treatment of HCV infection that have improved efficacy and fewer side effects when administered in both kidney transplant candidates and recipients.

Abstract
Clinical outcomes in kidney transplant recipients (KTRs) with hepatitis B virus (HBV) have not been thoroughly evaluated. Here, we investigated recent posttransplant clinical outcomes of KTRs with HBV and compared them with KTRs with hepatitis C virus (HCV) and seronegative KTRs.Of 3855 KTRs from April 1999 to December 2011, we enrolled 3482 KTRs who had viral hepatitis serology data; the patients were followed up for 89.1 ± 54.1 months. The numbers of recipients with HBV and HCV were 160 (4.6%) and 55 (1.6%), respectively. We analyzed the clinical outcomes, including overall mortality and graft failure, among patients who had undergone kidney transplantation.Patients with HBV showed poorer survival (P = 0.019; adjusted hazard ratio [HR] = 2.370; 95% confidence interval [CI]: 1.155-4.865) than KTRs without HBV. However, the graft survival of patients with chronic hepatitis B did not differ from that of patients without HBV. Hepatic complications were the primary causes of mortality of KTRs with HBV. Mortality significantly correlated with a higher grade of inflammation (P = 0.002) and with the use of lamivudine or adefovir antiviral treatment (P = 0.016). HBV-positive KTRs treated with the new-generation antiviral agent entecavir showed improved patient survival compared with KTRs receiving lamivudine (log-rank P = 0.050). HCV did not affect patient survival; however, it increased the incidence of graft failure (P = 0.010; adjusted HR = 2.899; 95% CI: 1.289-6.519). KTRs with HCV had an increased incidence of acute rejection (log-rank P = 0.005, crude HR = 2.144; 95% CI: 1.341-3.426; P = 0.001).KTRs with chronic hepatitis B may exhibit poor survival due to post-transplantation hepatic complications. Pretransplant histological liver evaluations and adequate antiviral management with potent nucleoside/nucleotide analogues are needed to improve the survival of KTRs with chronic hepatitis B even when liver function is within the normal range.

Abstract
With a worldwide prevalence of 6% to 40% among patients with end-stage renal disease, hepatitis C virus (HCV) infection is a significant cause of comorbidity in kidney transplant candidates and recipients alike. Hepatitis C infection negatively impacts patient and allograft outcomes, predisposes to progressive liver disease and increases the risks of glomerular disease as well as new onset diabetes after transplantation. Treatment options until now have revolved around interferon, limited in efficacy, restricted to pretransplant administration because of concerns related to allograft dysfunction and immune stimulation, and fraught with high rates of intolerance. Direct-acting antivirals therapies are now emerging, providing the opportunity to effectively cure chronic HCV infection and to reduce the burden of hepatic and extrahepatic complications of HCV that are observed in kidney recipients, thereby offering hope of improved patient outcomes. Against a description of the major outcomes and risks that HCV+ kidney candidates and recipients encounter, and a summary of the pertinent studies of interferon-based therapies in this population, this review discusses the potential role for emerging direct-acting antivirals, proposing treatment algorithms that should be considered in the management of these complex patients. Conundrums relating to the new treatment, including the potential impact on the utilization of kidneys from HCV-infected donors, are presented.

Abstract
The evidence that chronic hepatitis C plays a detrimental role in survival among patients on maintenance dialysis or renal transplant recipients promotes the antiviral treatment of hepatitis C virus (HCV) among chronic kidney disease patients. Also, it seems that HCV infection is associated with an increased risk of developing chronic kidney disease in the adult general population. Interferon-based regimens have provided limited efficacy and safety among chronic kidney disease patients, whereas the advent of the new direct-acting antivirals for the treatment of hepatitis C (launched over the past 5 years) has given the opportunity to reach sustained virologic response rates of 90% for many patient groups. Unfortunately, poor information exists regarding the antiviral treatment of hepatitis C in the chronic kidney disease population. The first published data on the treatment of hepatitis C among patients with chronic kidney disease (stage 4-5) and HCV genotype 1 regard the grazoprevir (NS3/4A protease inhibitor) and elbasvir (NS5A inhibitor) combination; excellent efficacy (sustained viral response, 94.3%; 115/122) and safety have been achieved. Preliminary evidence on the combined treatment of sofosbuvir (NS5B inhibitor) and simeprevir (NS3/4A inhibitor) has given a viral response of 89%, but the size of the study group (n = 38 patients with end-stage renal disease) was small. Some phase 2 and 3 clinical trials based on other antiviral combinations (3D regimen, sofosbuvir/ledipasvir, or other sofosbuvir-containing approaches) are ongoing. Thus, the antiviral regimens based on direct-acting antivirals promise to play a pivotal role in the eradication of hepatitis C among kidney disease patients. Direct-acting antivirals are very expensive; in an era of cost containment this is a crucial point either in developed and developing countries. Adverse drug reactions resulting from concomitantly administered medications are another ongoing concern for patients undergoing HCV treatment, particularly for chronic kidney disease patients who have a heavy burden of comorbidities.

Abstract
BACKGROUND Hepatitis C virus (HCV) outbreaks among patients on hemodialysis are still an important health concern all over the world. AIMS We performed a systematic review of reports on HCV outbreaks within dialysis units of developed and less-developed countries (between 1992 and 2015) to evaluate risk factors and practices associated with patient-to-patient transmission of HCV in this setting. METHODS The research was performed using the PubMed Database and the Outbreak Database; studies were selected according to the PRISMA algorithm. Inclusion criteria were established before the papers were retrieved in order to avoid selection biases. RESULTS 36 papers reported on 45 outbreaks that involved 335 unique patients on maintenance hemodialysis; no fatal cases were detected. Nosocomial transmission of HCV was confirmed by phylogenetic analysis in most (n=31; 69%) reports. Sharing contaminated hemodialysis machines and multidose vials (heparin or saline solution) was suggested responsible for HCV transmission in 8 (18%) and 6 (13%) outbreaks, respectively. Breaches in environmental cleaning and disinfection practices, and failures in medication preparation and administration practices was considered in 29 (65%) outbreaks; however, the exact mechanism of transmission of HCV could not be ascertained in each facility where an outbreak occurred. CONCLUSIONS Our systematic review of reports on hepatitis C virus outbreaks shows that, although the full extent of HCV transmission in dialysis units is unknown, outbreaks continue to occur. Full compliance to standard/specific infection control procedures and routine serologic screening for HCV antibody play a pivotal role for preventing the transmission of HCV within hemodialysis units.

Abstract
The advent of direct-acting anti-viral (DAA) drugs is dramatically changing the treatment of hepatitis C virus (HCV) in patients with intact kidney function ('cure rates' >90% and infrequent adverse events). The information on efficacy and safety of DAAs for HCV therapy in patients with renal failure is limited. We have reviewed the available evidence regarding efficacy and safety of numerous DAAs (boceprevir, telaprevir, sofosbuvir, simeprevir, grazoprevir, elbasvir, ombitasvir, paritaprevir, ritonavir, dasabuvir, ledispavir, daclatasvir, asunaprevir, beclabuvir) in treating HCV-infected patients with renal impairment and/or end-stage renal disease. The major limitation of this review is the paucity of published data and its reliance on abstracts and product monographs. Preliminary data suggest that combination antiviral therapy (grazoprevir and elbasvir) is provided with great efficacy in patients with HCV genotype 1 and chronic kidney disease stage 4 or 5 including those on intermittent dialysis, SVR12, 99% (114/115), according to a per-protocol analysis. In another trial, patients with HCV genotype 1 and chronic kidney disease stage 4 or 5 were given the 3D regimen; an interim evaluation reported that all patients completing treatment to date had viral response (100%, 14/14) but data on sustained viral response are under evaluation. Treatments were generally well tolerated.

Abstract
The landscape of therapeutic options for hepatitis B and C has changed drastically over the course of 2 decades. There are now novel, effective, well-tolerated, oral antiviral agents being used to successfully control chronic hepatitis B (HBV) infections and cure chronic hepatitis C (HCV) infections. However, patients with CKD were rarely included in the Phase II and III randomized trials for these medications. This paucity of data and the high prevalence of comorbidities associated with CKD pose distinct challenges to physicians treating chronic hepatitis B virus and hepatitis C virus infections in the setting of kidney insufficiency/failure. Thus, this review will attempt to summarize the current data regarding novel antiviral therapies for HBV and HCV in the CKD population.

Abstract
PURPOSE OF REVIEW Hepatitis C virus (HCV)-positive donor allografts may be considered for HCV-positive recipients, but are underutilized. With new effective antiviral treatments, we aim to review data on the use of HCV-positive allografts in solid organ transplantation and place them in the context of the changing HCV landscape. RECENT FINDINGS Hepatitis C is the most common indication for liver transplant in the USA and Europe and a significant comorbidity in patients on the waitlist for nonliver solid organ transplantation. Patients with HCV on the waitlist for nonliver solid organ transplantation have worse outcomes compared with those without HCV. However, survival after transplantation is improved compared with those who remain on the waitlist. There has been concern that use of HCV-positive allografts would lead to worse post-transplant outcomes. However, more recent data suggest that transplant outcomes for recipients who accept HCV-positive donor allografts may be comparable with those who receive HCV-negative allografts. Emerging treatments to eradicate HCV have further improved the course of HCV-positive individuals, with improved efficacy and reduced side-effects. SUMMARY In view of the changing landscape of hepatitis C treatment and reduced wait time on the transplant waiting lists for those accepting HCV-positive donors, future use of select HCV-positive donors in solid organ transplantation should be encouraged.

Abstract
INTRODUCTION The recent development of new direct acting antivirals constitutes a clinical revolution in the field of hepatitis C therapy. Different drugs with direct antiviral effects and very high potency have been developed, changing the current scenario and prognosis of hepatitis C-related liver disease. This review aims to clarify the current stage of the different antiviral strategies in patients with chronic hepatitis C infection by analyzing the specific efficacy of each combination. AREAS COVERED Data have been extracted from the most important published clinical trials, cumulative real-world experience reports and data from the most relevant studies presented in the last international meetings (European and American International Liver Congresses). In addition, data from the recently updated international guidelines have also been included. EXPERT OPINION Although there are many differences in health-care budgets among countries in the world which will surely compromise drug availability and treatment decisions, this review aims to give a general and brief recommendation to help treating physicians to choose the best option to treat hepatitis C.

Transmission of Hepatitis C Virus From Organ Donors Despite Nucleic Acid Test Screening. Am J Transplant 2015; 15:1827-35.

Abstract
Nucleic acid testing (NAT) for hepatitis C virus (HCV) is recommended for screening of organ donors, yet not all donor infections may be detected. We describe three US clusters of HCV transmission from donors at increased risk for HCV infection. Donor's and recipients' medical records were reviewed. Newly infected recipients were interviewed. Donor-derived HCV infection was considered when infection was newly detected after transplantation in recipients of organs from increased risk donors. Stored donor sera and tissue samples were tested for HCV RNA with high-sensitivity quantitative PCR. Posttransplant and pretransplant recipient sera were tested for HCV RNA. Quasispecies analysis of hypervariable region-1 was used to establish genetic relatedness of recipient HCV variants. Each donor had evidence of injection drug use preceding death. Of 12 recipients, 8 were HCV-infected-6 were newly diagnosed posttransplant. HCV RNA was retrospectively detected in stored samples from donor immunologic tissue collected at organ procurement. Phylogenetic analysis showed two clusters of closely related HCV variants from recipients. These investigations identified the first known HCV transmissions from increased risk organ donors with negative NAT screening, indicating very recent donor infection. Recipient informed consent and posttransplant screening for blood-borne pathogens are essential when considering increased risk donors.
