Abstract
PURPOSE OF REVIEW There has been an ongoing disparity between the number of organs available for solid organ transplantation (SOT) relative to the need. This has resulted in significant waitlist mortality, may affect transplant outcomes due to transplants being performed on sicker patients and may even increase healthcare costs due to extended hospital stays. Transplanting organs from hepatitis C virus (HCV)-infected donors into uninfected recipients (D+/R-) is now a reality, due to the advent of highly affective direct-acting antivirals (DAAs) which not only have very high efficacy, but also a favorable side effect and drug-drug interaction profile. RECENT FINDINGS Data from multiple centers reporting outcomes of kidney, liver, heart, lung and liver-kidney transplant during the past few years reveal that SOT from HCV-infected donors into noninfected recipients is safe, efficacious and can result in excellent recipient outcomes, with an opportunity to decrease the time on the waitlist, waitlist mortality and to improve outcomes after transplant due to less morbidity at the time of surgery. When livers are the transplanted organ, 8-12 weeks of DAA treatment will be required. For other organs, 2-4 weeks is likely sufficient. The available DAAs have profiles such that patients with all genotypes, with or without renal insufficiency an on renal replacement therapy and those who fail treatment may be successfully treated, with a sustained virologic response rate of more than 95%. Based upon the available data, starting DAAs shortly after transplant will likely limit posttransplant complications. that This will require cooperation between the transplant team, transplant hospital and insurer providing medication coverage. SUMMARY SOT from HCV infected recipients is safe, is associated with excellent outcomes and should be considered for recipients who would benefit from receiving an organ earlier than they would if they waited for an organ from an uninfected donor.

Abstract
BACKGROUND/AIMS As the most common liver disease in hemodialysis patients, chronic hepatitis C (CHC) can cause cirrhosis and hepatocellular carcinoma, even increase in renal-related mortality. In Turkey, the frequency of anti-hepatitis C virus (HCV) antibodies in hemodialysis patients ranged from 31.4% to 51%. Until recently, the mainstay of the CHC treatment for these patients was pegylated interferon with potential toxicities and low sustained virological response. The 3D regimen, a combination of four drugs (ombitasvir, paritaprevir, dasabuvir, and ritonavir), has recently been used for patients with chronic kidney disease infected with genotype 1a and 1b HCV. The aim of the present study was to present results of 3D treatment for patients with hemodialysis-dependent chronic renal failure (CRF) who were chronically infected with HCV. MATERIALS AND METHODS Overall, 25 patients with hemodialysis-dependent CRF who were infected with genotype 1a/1b HCV have been treated using the 3D regimen in our gastroenterology clinic between July 2016 and October 2017. Three patients were administered additional ribavirin 200 mg/day. Serum HCV RNAs, blood chemistry, blood count, and side effects were recorded at 0, 4, and 12 weeks. RESULTS All 25 patients completed and well tolerated their planned treatment. At the end of 4 weeks, the viral response (defined as HCV RNA clearance) rate was 92%. At the end of 12 weeks of treatment and 3 months after treatment, viral response rates were both 100%. CONCLUSION We observed that the treatment with 3D regimen in hemodialysis patients infected with genotype 1 hepatitis C is highly effective and well tolerated.

Eradication of HCV Infection with the Direct-Acting Antiviral Therapy in Renal Allograft Recipients. BIOMED RESEARCH INTERNATIONAL 2019; 2019:4674560.

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
BACKGROUND Previous studies have demonstrated inferior patient and graft survival following kidney transplant (KT) in HIV+/HCV+ coinfected patients compared to HIV+/HCV- recipients. However, these studies were conducted prior to the availability of direct-acting antiviral (DAA) agents and data in the modern era are lacking. METHODS Single center retrospective study of HIV+/HCV+ coinfected KT recipients (2007-2017). Outcomes were assessed for the pre-DAA and post-DAA (ie, after December 2013) eras including 1-year patient survival, death-censored graft survival, and acute rejection; and serious infections (defined as infections requiring admission to the intensive care unit during initial transplant hospitalization or re-admission to the hospital after discharge) within the first 6 months post-transplant. RESULTS A total of 13 consecutive HIV+/HCV+ recipients were identified. Median time of post-transplant follow-up was 722 days. Seven patients were transplanted in the DAA era; five of them had anti-HCV Ab+ donors, with two donors being HCV NAT positive; all received DAA therapy, six of them post-transplant (median time from KT to DAA: 83 days; IQR, 54-300). All the patients in the pre-DAA era were on a protease inhibitor-containing ART regimen. One-year patient and death-censored graft survivals were 83% and 67%, respectively, for the patients transplanted in the pre-DAA era, and 100% for both outcomes in the subgroup of patients transplanted in the post-DAA era (P > 0.05). Compared to patients in the post-DAA era, those in the pre-DAA era had higher incidence of serious infections (0 vs 67%; P = 0.02). Acute rejection exclusively occurred in the pre-DAA group (n = 1; 17%). CONCLUSIONS Outcomes of HIV+/HCV+ KT recipients, including HIV-/HCV+ to HIV+/HCV+ transplants, in the DAA era were excellent in this small cohort. Larger studies are needed.

Abstract
BACKGROUND Direct-acing antiviral agents are highly efficient treatment options for chronic hepatitis C virus (HCV) infection after renal allograft transplantation. Treatment options for patients with impaired graft function remain limited. Therefore, we assessed the effectiveness and safety of grazoprevir/elbasvir therapy for patients with chronic HCV infection and impaired renal allograft function. METHODS Eleven renal allograft recipients with therapy-naïve HCV genotype (GT) 1a, 1b, or 4 were treated with the fixed-dose combination of elbasvir/grazoprevir without ribavirin for 12 weeks. All recipients exhibited impaired graft function with an average glomerular filtration rate lower than 30 mL/min per 1.73 m2. Clinical data were retrospectively reviewed for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, viral load, laboratory values, and potential adverse effects. RESULTS Seven (64%) patients exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 2; HCV GT1b, n = 5). The other 4 patients exhibited a virologic response within 8 weeks (HCV GT1b, n = 3; HCV GT 4, n = 1). All patients exhibited a sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Few adverse effects were reported. Impaired renal allograft function and proteinuria remained stable. For most patients, only moderate adjustments to the tacrolimus dosage were necessary for maintaining sufficient trough levels. CONCLUSIONS This treatment appears to be safe and effective for renal transplant recipients with impaired allograft function and is a promising treatment option for eradicating HCV infection in this patient population.

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
Treatments for hepatitis C virus (HCV) have advanced greatly, becoming more efficacious with fewer adverse events, due to the availability of direct-acting antiviral agents, which target specific steps in the HCV life cycle. Recently, a combination regimen consisting of the HCV nonstructural protein 5A inhibitor elbasvir (EBR) and the HCV NS3/4A protease inhibitor grazoprevir (GZR) was approved for the treatment of patients with chronic HCV and genotypes (Gts) 1 and 4 in various countries. In Phase III trials, the combination of EBR/GZR (fixed-dose combination table or single agent) for 12 or 16 weeks of treatment with or without ribavirin resulted in a high sustained virological response at 12 weeks in treatment-naïve and treatment-experienced patients with HCV Gt 1a, 1b, 4, or 6, including special populations, such as individuals with advanced chronic kidney disease, HCV-HIV coinfection, and compensated cirrhosis. In this review, we focus on the mode of action, pharmacokinetics, clinical applications, efficacy, and safety profile of EBR/GZR, including special populations who have been considered refractory from the extensive evidence of clinical trials.

Abstract
BACKGROUND Given the shortage of suitable donor hearts for cardiac transplantation, and the favorable safety and efficacy of current agents used to treat hepatitis C virus (HCV), our institution recently piloted transplantation of select patients using HCV-positive donors. METHODS Between September 2016 and March 2017, 12 HCV-naive patients and 1 patient with a history of treated HCV underwent heart transplantation (HT) using hearts from HCV-positive donors after informed consent. Patients who acquired HCV were referred to hepatology and treated with direct-acting anti-viral therapies (DAAs). Data collection and analysis were performed with institutional review board approval. RESULTS At the time of HT, mean age of recipients was 53 ± 10 years, and 8 patients (61.5%) were on left ventricular assist device support. After consent to consider an HCV-positive heart, mean time to HT was 11 ± 12 days. Nine of 13 patients (69%) developed HCV viremia after transplant, including 8 who completed DAA treatment and demonstrated cure, as defined by a sustained virologic response 12 weeks after treatment. One patient died during Week 7 of his treatment due to pulmonary embolism. DAAs were well tolerated in all treated patients. CONCLUSIONS In the era of highly effective DAAs, the use of HCV-positive donors represents a potential approach to safely expand the donor pool. Additional follow-up is needed to elucidate long-term outcomes.

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
Direct-acting antiviral agents (DAAs) are a safe and effective treatment for chronic hepatitis C (CHC). This may be particularly valuable for patients with severe comorbidities or baseline conditions, including non-liver solid organ transplant. We report cases of two heart transplant recipients with CHC treated with DAAs (sofosbuvir and daclatasvir) achieving sustained virological response. Treatment was well tolerated and no relevant side effects were observed. The drug-drug interactions and graft function were carefully monitored.

Abstract
BACKGROUND Treatment of chronic hepatitis C virus (HCV) infection after renal allograft transplantation has been an obstacle because of contraindications associated with IFN-based therapies. Direct-acting antiviral agents are highly efficient treatment options that do not require IFN and may not require ribavirin. Therefore, we assessed the efficacy and safety of sofosbuvir and ledipasvir in renal transplant patients with chronic HCV infection. METHODS Fifteen renal allograft recipients with therapy-naive HCV genotype (GT) 1a, 1b, or 4 were treated with the combination of sofosbuvir and ledipasvir without ribavirin for 8 or 12 weeks. Clinical data were retrospectively analyzed for viral kinetics and for renal and liver function parameters. Patients were closely monitored for trough levels of immunosuppressive agents, laboratory values, and potential adverse effects. RESULTS Ten patients (66%) exhibited a rapid virologic response within 4 weeks (HCV GT1a, n = 4; HCV GT1b, n = 6). The other 5 patients exhibited a virologic response within 8 (HCV GT 1b, n = 4) or 12 weeks (HCV GT4, n = 1). One hundred percent of patients exhibited sustained virologic response at week 12 after the end of treatment. Clinical measures of liver function improved substantially for all patients. Adverse events were scarce; renal transplant function and proteinuria remained stable. Importantly, dose adjustments for tacrolimus were necessary for maintaining sufficient trough levels. CONCLUSIONS The described regimen appears to be safe and effective for patients after renal transplant and is a promising treatment regimen for eradicating HCV in this patient population.

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

Abstract
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
Barriers to access and long-term complications remain a challenge in transplantation. Further advancements may be achieved through research priority setting with patient engagement to strengthen its relevance. We evaluated research priority setting in solid organ transplantation and described stakeholder priorities. Databases were searched to October 2016. We synthesized the findings descriptively. The 28 studies (n = 2071 participants) addressed kidney [9 (32%)], heart [7 (25%)], liver [3 (11%)], lung [1 (4%)], pancreas [1 (4%)], and nonspecified organ transplantation [7 (25%)] using consensus conferences, expert panel meetings, workshops, surveys, focus groups, interviews, and the Delphi technique. Nine (32%) reported patient involvement. The 336 research priorities addressed the following: organ donation [43 priorities (14 studies)]; waitlisting and allocation [43 (10 studies)]; histocompatibility and immunology [31 (8 studies)]; immunosuppression [21 (10 studies)]; graft-related complications [38 (13 studies)]; recipient (non-graft-related) complications [86 (14 studies)]; reproduction [14 (1 study)], psychosocial and lifestyle [49 (7 studies)]; and disparities in access and outcomes [10 (4 studies)]. The priorities identified were broad but only one-third of initiatives engaged patients/caregivers, and details of the process were lacking. Setting research priorities in an explicit manner with patient involvement can guide investment toward the shared priorities of patients and health professionals.

Abstract
Kidney transplantation alone in clinically compensated patients with cirrhosis is not well documented. Current guidelines list cirrhosis as a contraindication for kidney transplantation alone. This is an Institutional Review Board-approved retrospective study. We report our experience with a retrospective comparison between transplants in hepatitis C virus-positive (HCV(+)) patients without cirrhosis and HCV(+) patients with cirrhosis. All of the patients were followed for at least a full 3-year period. All of the deaths and graft losses were recorded and analyzed using Kaplan-Meier methodology. One- and three-year cumulative patient survival rates for noncirrhotic patients were 91% and 82%, respectively. For cirrhotic patients, one- and three-year cumulative patient survival rates were 100% and 83%, respectively (P = NS). One- and three-year cumulative graft survival rates censored for death were 94% and 81%, and 95% and 82% for the noncirrhosis and cirrhosis groups, respectively (P = NS). Comparable patient and allograft survival rates were observed when standard kidney allograft recipients were analyzed separately. This study is the longest follow-up document in the literature showing that HCV(+) clinically ompensated patients with cirrhosis may undergo kidney transplantation alone as a safe and viable practice.

Abstract
BACKGROUND Acute hepatitis E virus (HEV) infection in solid organ transplant recipients is rare, but can cause severe hepatic and extrahepatic complications. We sought to identify the pretransplant prevalence of HEV infection in heart and kidney candidates and any associated risk factors for infection. MATERIAL AND METHODS Stored frozen serum from patients undergoing evaluation for transplant was tested for HEV immunoglobulin G (IgG) antibodies and HEV RNA. All patients were seen at Mayo Clinic Hospital, Phoenix, Arizona, with 333 patients evaluated for heart (n = 132) or kidney (n = 201) transplant. HEV IgG antibodies (anti-HEV IgG) were measured by enzyme-linked immunosorbent assay, and HEV RNA by a noncommercial nucleic acid amplification assay. RESULTS The prevalence of anti-HEV IgG was 11.4% (15/132) for heart transplant candidates and 8.5% (17/201) for kidney transplant candidates, with an overall seroprevalence of 9.6% (32/333). None of the patients tested positive for HEV RNA in the serum. On multivariable analysis, age older than 60 years was associated with HEV infection (adjusted odds ratio, 3.34; 95% CI, 1.54-7.24; P = 0.002). CONCLUSIONS We conclude that there was no evidence of acute HEV infection in this pretransplant population and that older age seems to be associated with positive anti-HEV IgG.

Abstract
Reduction of cardiovascular death might have a significant effect on the long-term survival rates of renal transplant recipients (RTRs). The aim of the study was to assess the relation between arterial stiffness and graft function, adipose tissue content, and hydration status in patients after kidney transplantation (KTx).The study included 83 RTR patients (mean age: 55 ± 13 years) who had been admitted to a nephrology-transplantation outpatient clinic 0.5 to 24 years after KTx. Clinical and laboratory data were analyzed and eGFR was calculated with the CKD-EPI formula. Arterial stiffness was assessed in all RTRs with pulse wave propagation velocity (PWV) with the use of a complior device. In addition, fluid and nutritional status was assessed with a Tanita BC 418 body composition analyzer. The control group consisted of 31 hospital workers who received no medication and had no history of cardiovascular disease.Multivariable linear regression analysis, with PWV as a dependent variable, retained the following independent predictors in the final regression model: red blood cell distribution width (RDW) (B = 0.323; P = 0.004), age (B = 0.297; P = 0.005), tacrolimus therapy (B = -0.286; P = 0.004), and central DBP (B = 0.185; P = 0.041). Multivariable linear regression analysis with eGFR as a dependent variable retained the following independent predictors in the final regression model; creatinine concentration (B = -0.632; P = 0.000), hemoglobin (B = 0.280; P = 0.000), CRP (B = -0.172; P = 0.011), tacrolimus therapy (B = 0.142; P = 0.039), and triglycerides (B = -0.142; P = 0.035).Our data indicates that: kidney transplant recipients can present modifiable CVD risk factors linked to increased arterial stiffness, DBP, waist circumference, SCr, time on dialysis, CyA therapy, and visceral fat mass; RDW is a parameter associated with arterial stiffness; and parameters such as CyA therapy, time on dialysis, PWV, RDW, and triglycerides show negative associations with the allograft function assessed with eGFR.

Abstract
Hepatitis C virus (HCV) infection is estimated to affect 130-150 million people globally which corresponds to 2%-3% of the total world population. It remains the leading indication for liver transplant worldwide and has been demonstrated to negatively impact both patient and graft survival following non-hepatic organ transplantation. In the era of interferon-based therapy, although treatment and cure of HCV prior to non-hepatic transplant improved survival, tolerability and low cure rates substantially limited therapy. Interferon (IFN)-based therapy following non-hepatic solid organ transplant, due to the risk of allograft rejection, is generally contraindicated. Rapid advances in IFN-free therapy with direct acting antivirals (DAAs) in the last few years have completely changed the paradigm of hepatitis C therapy. Compared to IFN-based regimens, DAAs have less frequent and less severe adverse effects, shorter durations of therapy, and higher cure rates that are minimally impacted by historically negative predictors of response such as cirrhosis, ethnicity, and post-transplant state. Recent studies have shown that liver transplant (LT) recipients can be safely and effectively treated with DAA combination therapies; although data are limited, many of the principles of therapy in LT may be extrapolated to non-hepatic solid organ transplant recipients. Here we review the data on DAA combination therapies in transplantation, discuss the advantages and disadvantages of pre- vs post-transplant HCV therapy and future directions.

Abstract
Infectious diseases after solid organ transplantation (SOT) are a significant cause of morbidity and reduced allograft and patient survival; however, the influence of infection on the development of chronic allograft dysfunction has not been completely delineated. Some viral infections appear to affect allograft function by both inducing direct tissue damage and immunologically related injury, including acute rejection. In particular, this has been observed for cytomegalovirus (CMV) infection in all SOT recipients and for BK virus infection in kidney transplant recipients, for community-acquired respiratory viruses in lung transplant recipients, and for hepatitis C virus in liver transplant recipients. The impact of bacterial and fungal infections is less clear, but bacterial urinary tract infections and respiratory tract colonization by Pseudomonas aeruginosa and Aspergillus spp appear to be correlated with higher rates of chronic allograft dysfunction in kidney and lung transplant recipients, respectively. Evidence supports the beneficial effects of the use of antiviral prophylaxis for CMV in improving allograft function and survival in SOT recipients. Nevertheless, there is still a need for prospective interventional trials assessing the potential effects of preventive and therapeutic strategies against bacterial and fungal infection for reducing or delaying the development of chronic allograft dysfunction.

Englum BR, Ganapathi AM, Speicher PJ, Gulack BC, Snyder LD, Davis RD, Hartwig MG. Impact of donor and recipient hepatitis C status in lung transplantation. J Heart Lung Transplant 2015; 35:228-35. [PMID: 26615769 DOI: 10.1016/j.healun.2015.10.012] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2015] [Revised: 09/17/2015] [Accepted: 10/03/2015] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Studies of lung transplantation in the setting of donors or recipients with hepatitis C virus (HCV) have been limited but have raised concerns about outcomes associated with this infection. METHODS Lung transplant cases in the United Network for Organ Sharing (UNOS) database from 1994 to 2011 were analyzed for the HCV status of both donor and recipient. First, among HCV-negative recipients, those who received a lung from an HCV-positive donor (HCV(+) D) were compared with those who received an HCV-negative lung (HCV(-) D). Donor, recipient and operative characteristics as well as outcomes were compared between groups, and overall survival was compared after adjustment for confounders. In a second analysis, HCV-positive recipients (HCV(+) R) were compared with HCV-negative recipients (HCV(-) R). The analysis was stratified by era (1994 to 1999 and 2000 to 2011) and long-term survival was compared. RESULTS Of 16,604 HCV-negative patients in the UNOS database, 28 (0.2%) received a lung from an HCV(+) D, with use of HCV(+) D decreasing significantly over time. Overall survival (OS) was shorter in the HCV(+) D group (median survival: 1.3 vs 5.1 years; p = 0.002). Results were confirmed in adjusted analyses. After inclusion criteria were met, 289 (1.7%) of the lung transplant recipients were HCV(+) R. These patients appeared similar to their HCV(-) R counterparts, except they were older and had more limited functional status. OS was significantly lower in HCV-positive individuals during the early era (median survival: 1.7 vs 4.5 years; p = 0.004), but not the recent era (median survival: 4.4 vs 5.4 years; p = 0.100). Again, results were confirmed by adjusted analysis. CONCLUSIONS HCV-positive status is a rare problem when considering both lung recipients and donors. Current data demonstrate significantly worse outcomes for HCV-negative patients receiving an HCV(+) lung; however, since 2000, HCV(+) recipients undergoing lung transplantation appear to have survival approximating that of HCV(-) recipients, an improvement from previous years. Recent medical advances in treatment for HCV may further improve outcomes in these groups.

Abstract
Several classifications systems have been developed to predict outcomes of kidney transplantation based on donor variables. This study aims to identify kidney transplant recipient variables that would predict graft outcome irrespective of donor characteristics. All U.S. kidney transplant recipients between October 25,1999 and January 1, 2007 were reviewed. Cox proportional hazards regression was used to model time until graft failure. Death-censored and nondeath-censored graft survival models were generated for recipients of live and deceased donor organs. Recipient age, gender, body mass index (BMI), presence of cardiac risk factors, peripheral vascular disease, pulmonary disease, diabetes, cerebrovascular disease, history of malignancy, hepatitis B core antibody, hepatitis C infection, dialysis status, panel-reactive antibodies (PRA), geographic region, educational level, and prior kidney transplant were evaluated in all kidney transplant recipients. Among the 88,284 adult transplant recipients the following groups had increased risk of graft failure: younger and older recipients, increasing PRA (hazard ratio [HR],1.03-1.06], increasing BMI (HR, 1.04-1.62), previous kidney transplant (HR, 1.17-1.26), dialysis at the time of transplantation (HR, 1.39-1.51), hepatitis C infection (HR, 1.41-1.63), and educational level (HR, 1.05-1.42). Predictive criteria based on recipient characteristics could guide organ allocation, risk stratification, and patient expectations in planning kidney transplantation.

Abstract
PURPOSE OF REVIEW Transplantation is the best treatment for many patients with end-stage organ failure. Hepatitis C infection is prevalent among solid organ candidates and recipients and continues to represent a major source of morbidity and mortality. Prior interferon (IFN)-based therapies have been associated with limited efficacy and high rates of adverse events. Furthermore, prior IFN-based regimens are associated with high rates of allograft rejection limiting their use post-transplant. This review will outline the limited experience with current treatment regimens and how to incorporate the new hepatitis C virus (HCV) treatment regimens. RECENT FINDINGS The introduction of new direct-acting antiviral (DAA) agents against HCV has dramatically altered the landscape of treatment for HCV. Different all-oral regimens are currently available and are rapidly becoming the standard for treating patients with chronic hepatitis C. Excluding patients with liver disease or those who received liver transplant, those regimens have not been studied in patients awaiting solid organ transplant, or those transplanted. SUMMARY The safety and efficacy of DAAs in patients awaiting liver transplant and liver transplant recipients provide us with some insight and guidance on how to use those all-oral IFN-free regimens to allow effective treatment for patients who received or are awaiting nonliver solid organ transplants.

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
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.

Abstract
Innovative and exciting advances in the clinical science in solid organ transplantation continuously realize as the results of studies, clinical trials, international conferences, consensus conferences, new technologies and discoveries. This review will address to the full spectrum of news in transplantation, that verified by 2013. The key areas covered are the transplantation activity, with particular regards to the donors, the news for solid organs such as kidney, pancreas, liver, heart and lung, the news in immunosuppressive therapies, the news in the field of tolerance and some of the main complications following transplantation as infections and cancers. The period of time covered by the study starts from the international meetings held in 2012, whose results were published in 2013, up to the 2013 meetings, conferences and consensus published in the first months of 2014. In particular for every organ, the trends in numbers and survival have been reviewed as well as the most relevant problems such as organ preservation, ischemia reperfusion injuries, and rejections with particular regards to the antibody mediated rejection that involves all solid organs. The new drugs and strategies applied in organ transplantation have been divided into new way of using old drugs or strategies and drugs new not yet on the market, but on phase Ito III of clinical studies and trials.

Abstract
Reports of kidney transplantation (KTX) in recipients with hepatitis C virus (HCV+), human immunodeficiency virus (HIV+) or coinfection often do not provide adequate adjustment for donor risk factors. We evaluated paired deceased-donor kidneys (derived from the same donor transplanted to different recipients) in which one kidney was transplanted into a patient with viral infection (HCV+, n = 1700; HIV+, n = 243) and the other transplanted into a recipient without infection (HCV- n = 1700; HIV- n = 243) using Scientific Registry of Transplant Recipients data between 2000 and 2013. On multivariable analysis (adjusted for recipient risk factors), HCV+ conferred increased risks of death-censored graft survival (DCGS) (adjusted hazard ratio [aHR] 1.24, 95% confidence interval [CI] 1.04-1.47) and patient survival (aHR 1.24, 95% CI 1.06-1.45) compared with HCV-. HIV+ conferred similar DCGS (aHR 0.85, 95% CI 0.48-1.51) and patient survival (aHR 0.80, 95% CI 0.39-1.64) compared with HIV-. HCV coinfection was a significant independent risk factor for DCGS (aHR 2.33; 95% CI 1.06, 5.12) and patient survival (aHR 2.88; 95% CI 1.35, 6.12). On multivariable analysis, 1-year acute rejection was not associated with HCV+, HIV+ or coinfection. Whereas KTX in HIV+ recipients were associated with similar outcomes relative to noninfected recipients, HCV monoinfection and, to a greater extent, coinfection were associated with poor patient and graft survival.

Abstract
Renal dysfunction is a frequent complication in patients with end-stage liver disease awaiting orthotopic liver transplantation and in the post-liver transplant period. Although the stereotypical form of renal dysfunction is the hepatorenal syndrome, other causes of acute kidney injury in this population include prerenal azotemia and acute tubular necrosis. Renal injury in a patient with cirrhosis is associated with a poor prognosis.

Abstract
Liver disease secondary to chronic hepatitis C virus (HCV) infection is an important cause of morbidity and mortality in patients with end-stage renal disease (ESRD) on renal replacement therapy and after kidney transplantation (KT). Hemodialytic treatment (HD) for ESRD constitutes a risk factor for bloodborne infections because of prolonged vascular access and the potential for exposure to infected patients and contaminated equipment. Evaluation of HCV-positive/ESRD and HCV-positive/KT patients is warranted to determine the stage of disease and the appropriateness of antiviral therapy, despite such treatment is challenging especially due to tolerability issues. Antiviral treatment with interferon (IFN) is contraindicated after transplantation due to the risk of rejection, and therefore, treatment is recommended before KT. Newer treatment strategies of direct-acting antiviral agents in combination are revolutionizing HCV therapy, as a result of encouraging outcomes streaming from recent studies which report increased sustained viral response, low or no resistance, and good safety profiles, including preservation of renal function. KT has been demonstrated to yield better outcomes with respect to remaining on HD although survival after KT is penalized by the presence of HCV infection with respect to HCV-negative transplant recipients. Therefore, an appropriate, comprehensive, easily applicable set of clinical practice management guidelines is necessary in both ESRD and KT patients with HCV infection and HCV-related liver disease.

Abstract
The immunosuppressed state may arise due to medical illness or drug therapy, which can result in a diverse array of liver derangements. This article discusses the commonly-encountered immunosuppressed conditions and the associated specific liver diseases. Due to the frequency of blood-borne viral disease globally, viral hepatitis (hepatitis B and C) during chemotherapy, transplantation and the increasingly utilised biological therapies for autoimmune disorders is discussed. An overview of human immunodeficiency virus co-infection with hepatitis B and C is provided. This article aims to highlight the variety of liver diseases which can occur in clinically relevant, particularly iatrogenic, immunosuppressed conditions, and summarise learning and practice points for clinicians. Recognition and prevention of viral liver disease is crucial and early involvement of experts prior to administration of immunosuppressive therapy is advised.
