Abstract
This paper is an educationally focused article discussing how transplant infectious diseases (TID) providers balance the risks of accepting or rejecting an organ and have pushed barriers in organ transplantation. We emphasize the role TID providers play in the transplantation process as critical players on the transplant team. We discuss various donor-derived infections that were previously deemed unacceptable for donation due to concerns for transmission. Advances in medical knowledge have changed some of these situations. We discuss the critical role TID providers have in closing the gap between the thousands of patients on organ waitlists and the organ deficit faced each day. We believe TID providers have a unique opportunity to expand the donor pool by increasing education, expanding acceptable organ definitions, and expanding the boundaries of what we can do with potentially transmissible infections in organ transplantation.

Abstract
The advent of highly effective and well-tolerated direct-acting antiviral therapy has made it more feasible to transplant hepatitis C virus (HCV)-infected organs into HCV-negative recipients. This case report presents the outcomes of 4 patients who underwent multivisceral transplantation from HCV-nucleic acid test (NAT)-viremic donors, with 1 recipient also requiring a kidney transplant. All recipients received posttransplant direct-acting antiviral therapy with sofosbuvir/velpatasvir (SOF/VEL [Epclusa]). By the fourth week of therapy, none of the recipients exhibited detectable viral loads, and all achieved sustained virologic response at 12 weeks. Allograft function for HCV D+/R- recipients remained excellent throughout follow-up. One recipient died from posttransplant lymphoproliferative disorder and another developed end-stage renal disease; both outcomes were ostensibly unrelated to HCV-donor status. The other 2 patients are progressing well without any evidence of allograft rejection.

Abstract
BACKGROUND This study evaluates the clinical trends and impact of hepatitis C virus-positive (HCV+) donors on waitlist and posttransplant outcomes after heart transplantation. METHODS The United Network for Organ Sharing registry was queried to identify adult waitlisted and transplanted patients from January 1, 2015, to December 31, 2022. In the waitlist analysis, the candidates were stratified into 2 cohorts based on whether they were willing to accept HCV+ donor offers. Waitlist outcomes included 1-y cumulative incidences of transplantation and death/delisting. In the posttransplant analysis, the recipients were stratified into 2 cohorts with and without HCV nucleic acid test (NAT)-positive donors. Outcomes included 1- and 4-y posttransplant survival. Propensity score-matching was performed. Risk adjustment was performed using multivariable Cox regression. RESULTS During the study period, the number of centers using HCV NAT+ donors increased from 1 to 65 centers, along with the number of transplants. In the waitlist analysis, 26 648 waitlisted candidates were analyzed, and 4535 candidates (17%) were approved to accept HCV+ donors. Approval to accept HCV+ donors was associated with a higher likelihood of transplantation and a lower likelihood of death/delisting within 1 y of waitlisting. In the posttransplant analysis, 21 131 recipients were analyzed, and 997 recipients (4.7%) received HCV NAT+ hearts. The 1- and 4-y posttransplant survival were comparable between the recipients of HCV NAT+ and NAT- donors. Furthermore, the similar 1- and 4-y posttransplant survival persisted in the propensity score-matched comparison and multivariable Cox regression analysis. CONCLUSIONS Utilization of HCV+ donors is rising. Heart transplants using HCV+ donors are associated with improved waitlist and comparable posttransplant outcomes.

Real-world experience in treatment of donor-derived Hepatitis C virus in kidney transplant recipients with delayed initiation, shortened course glecaprevir/pibrentasvir versus standard of care. Transpl Infect Dis 2024:e14366. [PMID: 39226149 DOI: 10.1111/tid.14366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 07/30/2024] [Accepted: 08/09/2024] [Indexed: 09/05/2024]
Abstract
BACKGROUND There is limited literature describing the real-world practice of delayed initiation and shortened duration direct-acting antiviral (DAA) in kidney transplant recipients. We compared Hepatitis C virus (HCV) cure rates among kidney transplant recipients who received an HCV nucleic acid test positive (NAT +) kidney and were treated with sofosbuvir/velpatasvir (SOF/VEL) for 12 weeks or glecaprevir/pibrentasvir (G/P) for 8 weeks, a duration that is 4 weeks shorter than the guideline recommendation for treatment delay beyond 1-week post-transplant. METHODS Retrospective study of HCV-negative adult patients who received a kidney transplant from an HCV NAT+ donor between April 2019 and April 2022 treated with either SOF/VEL for 12 weeks or G/P for 8 weeks. The primary outcome was sustained virologic response 12 weeks after completion of therapy (SVR12). Secondary outcomes included time to DAA initiation, renal function, graft loss, patient death, liver function tests, and opportunistic infections. RESULTS 102 kidney transplant recipients were included with 36 treated with G/P and 66 treated with SOF/VEL. All 36 (100%) treated with G/P achieved SVR12. One patient in the SOF/VEL group failed to achieve SVR12 but received additional therapy and was cured. Time to DAA initiation was similar with a mean of 4 weeks. There was no difference in AST/ALT > 3x ULN or renal function. One rejection occurred in each group. No patient death or graft loss was observed. There was no difference in cytomegalovirus and BK viremia between groups. CONCLUSION: Delayed initiation of DAA therapy with 12 weeks of SOF/VEL or 8 weeks of G/P achieves SVR12 in kidney transplant recipients without significant adverse effects.

Regional Differences and Temporal Changes in the Utilization of HCV-Viremic Donors in Kidney Transplantation. Transplant Proc 2024; 56:1513-1521.

Abstract
INTRODUCTION Despite the data demonstrating an increased utilization of hepatitis C virus (HCV)-viremic kidneys, the acceptance and incorporation of HCV-viremic kidneys are not universal. We aimed to identify regional differences and their temporal changes in the utilization of HCV-viremic kidneys. METHODS Using the Organ Procurement and Transplantation Network database, HCV-viremic kidneys utilized in kidney transplants from March 15, 2019, to March 14, 2023, were included. The utilization of HCV-viremic kidneys across the United States and center-level clustering of HCV-viremic donor kidney transplants into HCV NAT-negative recipients (HCV D+/R- transplants) using Gini coefficients were examined. RESULTS Significant regional variations were observed, with regions 3, 10, and 11 accounting for 51% of all HCV-viremic kidney utilization. Region 9 benefited the most from HCV-viremic kidney transplants with a high influx of kidney imports from other regions (284.9% gain). Region 8 and region 6 encountered the most substantial losses, with net losses of -44.2% and -41.1%, respectively. HCV D+/R- transplants were concentrated in specific high-volume centers, but trends indicated a gradual increase in a more equitable distribution across centers over time. CONCLUSIONS Significant variations can be observed in the utilization of HCV-viremic kidneys throughout the United States. These variations highlight opportunities for kidney transplant centers in specific regions to adopt policies for HCV-viremic kidney transplants, thereby expanding their donor pool. Encouragingly, an increasing number of kidney transplant centers are adopting HCV D+/R- kidney transplants, indicating positive progress. These trends suggest a more balanced access to HCV-viremic kidneys ahead.

Abstract
Lung transplantation can improve the survival of patients with severe chronic pulmonary disorders. However, the short- and long-term risk of infections can increase morbidity and mortality rates. A non-systematic review was performed to provide the most updated information on pathogen, host, and environment-related factors associated with the occurrence of bacterial, fungal, and viral infections as well as the most appropriate therapeutic options. Bacterial infections account for about 50% of all infectious diseases in lung transplanted patients, while viruses represent the second cause of infection accounting for one third of all infections. Almost 10% of patients develop invasive fungal infections during the first year after lung transplant. Pre-transplantation comorbidities, disruption of physical barriers during the surgery, and exposure to nosocomial pathogens during the hospital stay are directly associated with the occurrence of life-threatening infections. Empiric antimicrobial treatment after the assessment of individual risk factors, local epidemiology of drug-resistant pathogens and possible drug-drug interactions can improve the clinical outcomes.

Abstract
INTRODUCTION The introduction of direct-acting antivirals (DAAs) has significantly transformed the therapeutic landscape for chronic C hepatitis virus (HCV) infection. However, there is still room for further improvement in optimizing therapy efficacy and minimizing adverse effects. AREAS COVERED This review is devoted to the rationale for adopting a personalized approach to HCV therapy. Specifically, we explore the role of host-related factors, such as sex or the presence of comorbidities. We thoroughly examine the implications of commonly encountered comorbidities, including HIV infection, chronic renal disease, liver cirrhosis, and other chronic viral hepatitis infections. Additionally, we discuss the prevalent drug-to-drug interactions between DAAs and other medications, while providing guidance on their management. Finally, we investigate viral-related issues that can influence treatment outcomes, such as viral genotype, quasi-species, and the presence of resistance-associated mutations. EXPERT OPINION Despite pivotal trials demonstrating efficacy rates exceeding 90% for currently available DAA regimens, there are still opportunities to optimize therapy outcomes and tailor treatment to each patient. This can be achieved through a meticulous evaluation of the patient's specific clinical conditions and comorbidities, a vigilant approach to manage potential drug interactions, and diligent patient follow-up.

Abstract
OBJECTIVES Before the advent of direct-acting antiviral therapy for hepatitis C virus, a large proportion of kidneys from donors with hepatitis C viremia were discarded. Hepatitis C virus is now amenable to effective treatment with excellent seronegativity rates. In this study, we review the outcomes of hepatitis C viremic kidneys transplanted into hepatitis C-naive recipients. MATERIALS AND METHODS In this retrospective observational study, we examined 6 deceased donor kidneys with hepatitis C viremia that were transplanted into hepatitis C-naive recipients between March 2020 and April 2021 at a single center. Because of health insurance constraints, patients were treated for hepatitis C virus with glecaprevir/pibrentasvir for 8 weeks following seroconversion posttransplant. Primary outcome measured was viral seroconversion; secondary outcomes included graft function, posttransplant complications, and all-cause mortality. RESULTS On average, patients seroconverted 6 days (range, 4-10 d) after transplant and began treatment 26 days (range, 15-37 d) after seroconversion. An 8-week course of antiviral treatment was successful in preventing acute hepatitis C virus infection in all patients. Posttransplant median creatinine was 1.96 mg/dL (range, 1-4.55 mg/dL), whereas median estimated glomerular filtration rate was 41.33 mL/min/1.73 m2 (range, 17-85 mL/min/1.73 m2). Patient survival rate was 66.7%, and death-censored graft survival rate was 100%. Two patients died from unrelated reasons: 1 from acute respiratory failure secondary to SARS-CoV-2 infection and 1 from posttransplant lymphoproliferative disorder. Two patients developed allograft rejection posttransplant (1 developed antibody mediated rejection, 1 developed borderline T-cell-mediated cellular rejection). Other major complications included neutropenia, fungal rash, SARS-CoV-2 infection, cytomegalovirus, BK virus, and Epstein-Barr virus reactivation. CONCLUSIONS Use of hepatitis C-viremic donor kidneys for transplant is a safe option and has great potential to increase the kidney donor pool, as long as high index of suspicion is maintained for allograft rejection and opportunistic infections.

Abstract
Background Organ transplantation from donors with hepatitis C viremia (HCV) to recipients without HCV (HCV D+/R-) has excellent medical outcomes. Less is known about the psychosocial impact and experiences of HCV D+/R- recipients, particularly outside of clinical trials. Methods We conducted in-depth, semistructured interviews with 24 HCV D+/R- recipients (kidney, n = 8; lung, n = 7; liver, n = 5; heart, n = 3; simultaneous heart and kidney, n = 1) who received transplants outside of clinical trials and were treated for HCV after transplant to assess their experiences and perspectives. We used thematic analysis to analyze the interviews. Results Interviewees' reasons for accepting an HCV D + organ were based on perceived benefits and confidence in the effectiveness of HCV treatment. The majority (62%) received HCV treatment within 1 month after transplant (range, 1 day-2 months). Most interviewees reported positive transplant outcomes, including reduced wait times and improved survival, health, physical activity, and quality of life. Overall, themes and experiences did not differ significantly between different organ transplant types. Generally, interviewees did not perceive stigma from those aware of the HCV D+ transplant; yet, disclosure was selective and a few recipients reported concerns from family members about posttransplant HCV transmission risk. Other common concerns included treatment costs and delays, which were not always anticipated by recipients. Conclusions Our findings suggest that HCV D+/R- kidney, liver, and heart and lung transplant recipients outside of clinical trials had overall positive experiences. However, HCV transmission risk, treatments costs, and treatment delays were a source of concern that might be mitigated with targeted pretransplant education.

[PMID: 37871798 DOI: 10.1016/j.ajt.2023.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 09/14/2023] [Accepted: 10/06/2023] [Indexed: 10/25/2023]
Abstract
Curative hepatitis C virus (HCV) therapy has increased transplantation from HCV-infected nucleic acid test-positive donors to HCV-uninfected recipients (D+/R-). We evaluated outcomes of early and late HCV treatment among D+/R- nonliver organ transplants. Patients received HCV regimens per local standard (n = 10 sites). Outcomes were compared between early and late treatments. Early treatment regimens (ETR) (n = 56) were initiated pretransplantation to day 7 posttransplant. Late treatment regimens (LTRs) (n = 102) began median 31 (range, 8-114) days posttransplant. There were 79 kidney, 50 lung, 23 heart, and 6 mixed transplants, similar between groups. HCV RNA was quantifiable in 98% of LTR versus 44.6% of ETR recipients (P < .001). Mean (range) days on treatment were 28 (7-93) ETR and 81 (51-111) LTR (P < .0001). There were no virological failures with ETR, but relapse (n = 3) and nonresponse (n = 2) in LTR (P = .16), including fibrosing cholestatic hepatitis postrelapse (n = 1). Sustained virological response was 100% (95% confidence interval, 93.4-100.0) in ETR (n = 54) and 94.9% (95% confidence interval, 88.5-98.3) in LTR (n = 98). Acute rejection occurred in 11 (19.6%) ETR and 25 (24.5%) LTR. In total, 11 HCV-unrelated deaths occurred: 8 ETR and 3 LTR. Organ transplantation from HCV-infected nucleic acid test-positive donors to HCV-uninfected recipients was safe. ETR led to fewer virological failures with shorter treatment duration, supporting recommendations to initiate treatment promptly posttransplant.

Abstract
INTRODUCTION Utilization of hepatitis C viremic (HCV+) deceased donor kidneys (DDKT) for aviremic recipients increases opportunities for transplantation with excellent short-term outcomes. Our primary aim was to understand longer-term outcomes, specifically assessing kidney and liver function in the first year posttransplant. METHODS This was a retrospective single-center study of adult DDKT recipients of HCV+ kidneys (cases) matched 1:1 to recipients of HCV- kidneys (comparators). Between-group outcomes were analyzed using comparisons of means and proportions, survival analysis methods, and multivariable mixed effects models. RESULTS Sixty-five cases and 65 comparators had statistically comparable demographic and clinical characteristics. There were no between-group differences in serum creatinine or estimated glomerular filtration rate at month 12 (p = .662) or in their trajectories over months 1-12 (p > .292). Within the first 60 days, rates of liver function values >3 times upper limit of normal among cases were comparable to comparators for aspartate aminotransferase (AST) (14% vs. 6%, p = .242) and higher for alanine transaminase (ALT) (23% vs. 6%, p = .011). AST declined during the first 8 weeks (p = .005) and stabilized for both groups (p = .406) during the following 10 months. ALT declined during the first 8 weeks (p < .001), continued to decline over months 3-12 (p = .016), and the trajectory was unrelated to antiviral therapy initiation among cases. CONCLUSIONS Aviremic recipients of HCV+ kidneys had comparable kidney outcomes to matched recipients of HCV- kidneys. Despite more HCV+ recipients having an elevation in ALT within the first 60 days, ALT values normalized with no identified liver complications attributed to HCV.

Abstract
PURPOSE A case of BK nephropathy in a kidney transplant recipient who received an organ from a hepatitis C virus (HCV)-positive donor is reported. SUMMARY A 66-year-old male negative for HCV with chronic kidney disease secondary to diabetic glomerulosclerosis received a kidney transplant from an HCV-viremic donor. His initial postoperative course was uncomplicated, and HCV treatment with glecaprevir/pibrentasvir was initiated after discharge. On postoperative day (POD) 60, the patient developed BK viremia and his mycophenolate mofetil dose was decreased. Over the next few months, the BK viral load increased, with mycophenolate mofetil stopped and the tacrolimus goal lowered in response. On POD 130, the patient was admitted for a hypertensive crisis and found to have decreased renal function. During this hospitalization, the patient received a course of intravenous immune globulin (IVIG). Despite an initial response to the modification of immunosuppression therapy and several courses of IVIG over the following months, the patient's renal function continued to decline. At 18 months after transplantation, the patient was restarted on dialysis and taken off all immunosuppression. CONCLUSION Utilization of organs from HCV-positive donors in HCV-negative recipients allows for expansion of the donor pool and facilitates shorter times on the waitlist. Although initial data in HCV-discordant transplantation did not find an increased risk for opportunistic infections, more recent studies have shown that such risk may be present. This case report describes a patient who developed BK viremia and eventual allograft failure after an HCV-discordant transplantation.

Abstract
BACKGROUND With the introduction of direct-acting antiviral therapies (DAAs), the non-use rate of hepatitis C virus (HCV)-positive donor organs (D+) has decreased significantly. We present the donor, recipient, and transplant allograft characteristics, along with recipient outcomes, in one of the largest cohorts of HCV-D+ transplants into HCV-naïve recipients (R-). METHODS Charts of HCV D+/R- kidney (KT), liver (LT), and simultaneous liver-kidney (SLKT) transplant recipients between January 2019 and July 2022 were reviewed. Primary outcomes of interest included waitlist times and 1-year graft failure. Secondary outcomes included hospital and intensive care unit length of stay, post-transplant complications, effectiveness of DAA therapy, and characteristics of patients who relapsed from initial DAA therapy. RESULTS Fifty-five HCV D+/R- transplants at our center [42 KT (26 nucleic acid testing positive [NAT+], 16 NAT-), 12 LT (eight NAT+, four NAT-), and one SLKT (NAT+)] had a median waitlist time of 69 days for KT, 87 days for LT, and 15 days for SLKT. There were no graft failures at 1 year. All viremic recipients were treated with a 12-week course of DAAs, of which 100% achieved end of treatment response (EOTR)-85.7% (n = 30) achieved sustained virologic response (SVR) and 14.3% relapsed (n = 5; four KT, one LT). All relapsed recipients were retreated and achieved SVR. The most common post-transplantation complications include BK virus infection (n = 9) for KT and non-allograft infections (n = 4) for LT. CONCLUSIONS Our study has demonstrated no graft failures or recipient deaths at 1 year, and despite a 14.3% relapse rate, we achieved 100% SVR. Complications rates of D+/R- appeared comparable to national D-/R- complication rates. Further studies comparing D+/R- to D-/R- outcomes are needed.

Abstract
DESCRIPTION The Kidney Disease: Improving Global Outcomes (KDIGO) 2022 clinical practice guideline on prevention, diagnosis, evaluation, and treatment of hepatitis C in chronic kidney disease (CKD) is an update of the 2018 guideline from KDIGO. METHODS The KDIGO Work Group (WG) updated the guideline, which included reviewing and grading new evidence that was identified and summarized. As in the previous guideline, the WG used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to appraise evidence and rate the strength of recommendations and used expert judgment to develop recommendations. New evidence led to updating of recommendations in the chapters on treatment of hepatitis C virus (HCV) infection in patients with CKD (Chapter 2), management of HCV infection before and after kidney transplant (Chapter 4), and diagnosis and management of kidney disease associated with HCV infection (Chapter 5). Recommendations in chapters on detection and evaluation of hepatitis C in CKD (Chapter 1) and prevention of HCV transmission in hemodialysis units (Chapter 3) were not updated because of an absence of significant new evidence. RECOMMENDATIONS The 2022 updated guideline includes 43 graded recommendations and 20 ungraded recommendations, 7 of which are new or modified on the basis of the most recent evidence and consensus among the WG members. The updated guidelines recommend expanding treatment of hepatitis C with sofosbuvir-based regimens to patients with CKD glomerular filtration rate categories G4 and G5, including those receiving dialysis; expanding the donor pool for kidney transplant recipients by accepting HCV-positive kidneys regardless of the recipient's HCV status; and initiating direct-acting antiviral treatment of HCV-infected patients with clinical evidence of glomerulonephritis without requiring kidney biopsy. The update also addresses the use of immunosuppressive regimens in such patients.

Abstract
BACKGROUND Trials describing 4-12 week courses of direct-acting antiviral drugs (DAAs) to treat hepatitis C virus (HCV) transmission from infected donors to uninfected kidney transplant recipients (D+/R-transplants), may be limited in application by costs and delayed access to expensive DAAs. A short prophylactic strategy may be safer and cost-effective. Here, we report a cost minimization analysis using the health system perspective to determine the least expensive DAA regimen, using available published strategies. OBJECTIVES To conduct cost-minimization analyses (CMAs) from the health system perspective of four DAA regimens to prevent and/or treat HCV transmission from D+/R-kidney transplants. METHODS CMAs comparing 4 strategies: 1) 7-day prophylaxis with generic sofosbuvir/velpatasvir (SOF/VEL), with 12-week branded glecaprevir/pibrentasvir (G/P) for those with transmission; 2) 8-day branded G/P prophylaxis, with 12-week branded SOF/VEL/voxilaprevir for those with transmission; 3) 4-week perioperative generic SOF/VEL prophylaxis, with 12-week branded G/P for those with transmission; and 4) 8-week branded G/P "transmit-and-treat." We included data from published literature to estimate the probability of viral transmission in patients who received DAA prophylaxis, and assumed a 100% transmission rate for those who received the "transmit-and-treat" approach. RESULTS In base-case analyses, strategies 1 (expected cost [EC]: $2326) and 2 (expected cost: $2646) were less expensive than strategies 3 (EC: $4859) and 4 (EC: $18,525). Threshold analyses for 7-day SOF/VEL versus 8-day G/P suggested that there were reasonable input levels at which the 8-day strategy may be least costly. The threshold values for the SOF/VEL prophylaxis strategies (7-day vs. 4- week) indicated that the 4-week strategy is unlikely to be less costly under any reasonable value of the input variables. CONCLUSIONS Short duration DAA prophylaxis using 7 days of SOF/VEL or 8 days of G/P has the potential to yield significant cost savings for D+/R- kidney transplants.

Abstract
Utilization of hepatitis C (HCV) viremic kidneys is increasing in the United States. We examined racial disparity in this utilization using UNOS/OPTN data (2014-2020) and mixed effects models adjusting for donor/recipient/center factors. Included in the study were 58,786 adults receiving a deceased donor kidney transplant from 191 centers. Two thousand six hundred thirteen (4%) received kidneys from HCV-viremic donors. Of these, 1598 (61%) were HCV seronegative and 1015 (49%) were HCV seropositive. Among seronegative recipients, before adjusting for waiting time and education, Blacks (OR 0.69, 95%CI (0.60, 0.80)), Hispanics (OR 0.63, 95%CI (0.51, 0.79)), and Asians (OR 0.69, 95%CI (0.53, 0.90)) were less likely than Whites to receive HCV-viremic kidneys. In final models, effect of race was attenuated. Notably, shorter waiting time (OR 0.65, 95%CI (0.63, 0.67)) and increasing educational level (grade school less likely compared to high school OR 0.67, 95% CI (0.49, 0.92) and college more likely than high school (OR 1.16 95% CI (1.02, 1.31)) were associated with receipt of HCV-viremic kidneys. Among HCV-seropositive recipients, recipient race was not independently associated with receipt of HCV-viremic kidneys; however, centers with larger populations of Black waitlisted patients were more likely to utilize HCV-viremic kidneys (OR 1.71, 95%CI (1.20, 2.45)) compared to other centers. Our results suggest recipient race does not independently determine who receives HCV-viremic kidneys; however, other underlying factors including waiting time, education (among seronegative), and center racial mix (among seropositive) contribute to the current differential distribution of HCV-viremic kidneys among races.

Abstract
Hepatitis C virus (HCV) infection is a worldwide public health problem associated with significant morbidity and mortality. In the context of liver transplantation, the demand for organs continues to exceed the supply, prompting the consideration of using organs from HCV-positive donors in HCV-negative recipients. The introduction of direct-acting antivirals (DAAs), which have demonstrated great efficacy in eradicating the virus, has made transplantation of organs from donors with HCV infection possible. The present article provides a brief review of the current evidence on the use of organs from HCV-infected patients.

Abstract
BACKGROUND Demand for donor kidneys outstrips supply. Using kidneys from selected donors with an increased risk of blood-borne virus (BBV) transmission (hepatitis B virus and hepatitis C virus [HCV], human immunodeficiency virus) may expand the donor pool, but cost-effectiveness of this strategy is uncertain. METHODS A Markov model was developed using real-world evidence to compare healthcare costs and quality-adjusted life years (QALYs) of accepting kidneys from deceased donors with potential increased risk of BBV transmission, because of increased risk behaviors and/or history of HCV, versus declining these kidneys. Model simulations were run over a 20-y time horizon. Parameter uncertainty was assessed through deterministic and probabilistic sensitivity analyses. RESULTS Accepting kidneys from donors at increased risk of BBVs (2% from donors with increased-risk behaviors and 5% from donors with active or past HCV infection) incurred total costs of 311 303 Australian dollars with a gain of 8.53 QALYs. Foregoing kidneys from these donors incurred total costs of $330 517 and a gain of 8.44 QALYs. A cost-saving of $19 214 and additional 0.09 QALYs (~33 d in full health) per person would be generated compared with declining these donors. Increasing the availability of kidneys with increased risk by 15% led to further cost-savings of $57 425 and additional 0.23 QALY gains (~84 d in full health). Probabilistic sensitivity analysis using 10 000 iterations showed accepting kidneys from donors at increased risk led to lower costs and higher QALY gains. CONCLUSIONS Shifting clinical practice to accept increased BBV risk donors would likely produce lower costs and higher QALYs for health systems.

Abstract
These guidelines discuss the epidemiology, screening, diagnosis, posttransplant prophylaxis, monitoring, and management of endemic infections in solid organ transplant (SOT) candidates, recipients, and donors in South Asia. The guidelines also provide recommendations for SOT recipients traveling to this region. These guidelines are based on literature review and expert opinion by transplant physicians, surgeons, and infectious diseases specialists, mostly from South Asian countries (India, Pakistan, Bangladesh, Nepal, and Sri Lanka) as well as transplant experts from other countries. These guidelines cover relevant endemic bacterial infections (tuberculosis, leptospirosis, melioidosis, typhoid, scrub typhus), viral infections (hepatitis A, B, C, D, and E; rabies; and the arboviruses including dengue, chikungunya, Zika, Japanese encephalitis), endemic fungal infections (mucormycosis, histoplasmosis, talaromycosis, sporotrichosis), and endemic parasitic infections (malaria, leishmaniasis, toxoplasmosis, cryptosporidiosis, strongyloidiasis, and filariasis) as well as travelers' diarrhea and vaccination for SOT candidates and recipients including travelers visiting this region. These guidelines are intended to be an overview of each topic; more detailed reviews are being published as a special supplement in the Indian Journal of Transplantation .

Abstract
Liver diseases after kidney transplantation range from mild biochemical abnormalities to severe hepatitis or cirrhosis. The causes are diverse and mainly associated with hepatotropic viruses, drug toxicity and metabolic disorders. Over the past decade, the aetiology of liver disease in kidney recipients has changed significantly. These relates to the use of direct-acting antiviral agents against hepatitis C virus, the increasing availability of vaccination against hepatitis B and a better understanding of drug-induced hepatotoxicity. In addition, the emergence of the severe acute respiratory syndrome coronavirus 2 pandemic has brought new challenges to kidney recipients. This review aims to provide healthcare professionals with a comprehensive understanding of recent advances in the management of liver complications in kidney recipients and to enable them to make informed decisions regarding the risks and impact of liver disease in this population.

Abstract
To determine the effect of donor hepatitis C virus (HCV) infection on kidney transplant (KT) outcomes in the era of direct-acting antiviral (DAA) medications, we examined 68,087 HCV-negative KT recipients from a deceased donor between March 2015 and May 2021. A Cox regression analysis was used to estimate adjusted hazard ratios (aHRs) of KT failure, incorporating inverse probability of treatment weighting to control for patient selection to receive an HCV-positive kidney (either nucleic acid amplification test positive [NAT+, n = 2331] or antibody positive (Ab+)/NAT- [n = 1826]) based on recipient characteristics. Compared with kidney from HCV-negative donors, those from Ab+/NAT- (aHR = 0.91; 95% confidence interval [CI], 0.75-1.10) and HCV NAT+ (aHR = 0.89; 95% CI, 0.73-1.08) donors were not associated with an increased risk of KT failure over 3 years after transplant. Moreover, HCV NAT+ kidneys were associated with a higher 1-year estimated glomerular filtration (63.0 vs 61.0 mL/min/1.73 m2, P = .007) and lower risk of delayed graft function (aOR = 0.76; 95% CI, 0.68-0.84) compared with HCV-negative kidneys. Our findings suggest that donor HCV positivity is not associated with an elevated risk of graft failure. The inclusion of donor HCV status in the Kidney Donor Risk Index may no longer be appropriate in contemporary practice.

Abstract
OBJECTIVE The feasibility and 6-month outcome safety of lung transplants (LTs) from hepatitis C virus (HCV)-viremic donors for HCV-seronegative recipients (R-) were established in 2019, but longer-term safety and uptake of this practice nationally remain unknown. METHODS We identified HCV-seronegative LT recipients (R-) 2015-2020 using the Scientific Registry of Transplant Recipients. We classified donors as seronegative (D-) or viremic (D+). We used χ2 testing, rank-sum testing, and Cox regression to compare posttransplant outcomes between HCV D+/R- and D-/R- LT recipients. RESULTS HCV D+/R- LT increased from 2 to 97/year; centers performing HCV D+/R- LT increased from 1 to 25. HCV D+/R- versus HCV D-/R- LT recipients had more obstructive disease (35.7% vs 23.3%, P < .001), lower lung allocation score (36.5 vs 41.1, P < .001), and longer waitlist time (P = .002). HCV D+/R- LT had similar risk of acute rejection (adjusted odds ratio [aOR], 0.87; P = .58), extracorporeal membranous oxygenation (aOR, 1.94; P = .10), and tracheostomy (aOR, 0.42; P = .16); similar median hospital stay (P = .07); and lower risk of ventilator > 48 hours (aOR, 0.68; P = .006). Adjusting for donor, recipient, and transplant characteristics, risk of all-cause graft failure and mortality were similar at 30 days, 1 year, and 3 years for HCV D+/R- versus HCV D-/R- LT (all P > .1), as well as for high- (≥20/year) versus low-volume LT centers and high- (≥5/year) versus low-volume HCV D+/R- LT centers (all P > .5). CONCLUSIONS HCV D+/R- and HCV D-/R- LT have similar outcomes at 3 years posttransplant. These results underscore the safety of HCV D+/R- LT and the potential benefit of expanding this practice further.

Abstract
BACKGROUND In context of increasing complexity and risk of deceased kidney donors and transplant recipients, the impact of center volume (CV) on the outcomes of high-risk kidney transplants(KT) has not been well determined. METHODS We examined the association of CV and outcomes among 285 U.S. transplant centers from 2000-2016. High-risk KT were defined as recipient age ≥ 70 years, body mass index (BMI) ≥ 35 kg/m2, receiving kidneys from donors with kidney donor profile index(KDPI) ≥ 85%, acute kidney injury(AKI), hepatitisC + . Average annual CV for the specific-high-risk KT categorized in tertiles. Death-Censored-Graft-Loss(DCGL) and death at 3 months, 1, 5, and 10 years were compared between CV tertiles using Cox-regression models. RESULTS Two hundred fifty thousand five hundred seventy-four KT were analyzed. Compared to high CV, recipients with BMI ≥ 35 kg/m2 had higher risk of DCGL in low CV(aHR = 1.11,95%CI = 1.03-1.19) at 10 years; recipients with age ≥ 70 years had higher risk of death in low CV(aHR = 1.07,95%CI = 1.01-14) at 10 years. There was no difference of DCGL or death in low CV for donors with KDPI ≥ 85%, hepatitisC + , or AKI. CONCLUSIONS Recipients of high-risk KT with BMI ≥ 35 kg/m2 have higher risk of DCGL and recipients age ≥ 70 years have higher risk of death in low CV, compared to high CV. Future studies should identify care practices associated with CV that support optimal outcomes after KT.

Am J Transplant 2023:S1600-6135(23)00342-8. [PMID: 36893936 DOI: 10.1016/j.ajt.2023.03.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 02/06/2023] [Accepted: 03/01/2023] [Indexed: 03/09/2023]
Abstract
Despite data demonstrating increased utilization of kidneys from hepatitis C virus (HCV)-infected donors, it is unknown whether this is due to an increase in the donor pool or improved organ utilization and whether data from early pilot trials were temporally associated with changes in organ utilization. We used data from the Organ Procurement and Transplantation Network on all kidney donors and recipients of kidney transplants from January 1, 2015, to March 31, 2022 to evaluate temporal changes using joinpoint regression. Our primary analyses compared donors on the basis of their HCV viremic status (HCV-infected vs HCV-negative). Kidney utilization changes were assessed by evaluating the kidney discard rate and kidneys transplanted per donor. A total of 81 833 kidney donors were included in the analysis. There was a statistically significant decrease in the discard rates of HCV-infected kidney donors from 40% to just over 20% over a 1-year period, with a concurrent increase in kidneys transplanted per donor. This increased utilization occurred in tandem with the publication of pilot trials involving HCV-infected kidney donors in HCV-negative recipients rather than an increase in the donor pool. Ongoing clinical trials may strengthen existing data, which could result in this practice becoming the accepted standard of care.

World J Transplant 2023; 13:44-57. [PMID: 36908306 PMCID: PMC9993188 DOI: 10.5500/wjt.v13.i2.44] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 11/07/2022] [Accepted: 12/21/2022] [Indexed: 02/16/2023] Open
Abstract
BACKGROUND As Hepatitis C virus infection (HCV+) rates in kidney donors and transplant recipients rise, direct-acting antivirals (DAA) may affect outcomes.
AIM To analyze the effects of HCV+ in donors, recipients, or both, on deceased-donor (DD) kidney transplantation (KT) outcomes, and the impact of DAAs on those effects.
METHODS The Organ Procurement and Transplantation Network data of adult first solitary DD-KT recipients 1994-2019 were allocated into four groups by donor and recipient HCV+ status. We performed patient survival (PS) and death-censored graft survival (DCGS) pairwise comparisons after propensity score matching to assess the effects of HCV+ in donors and/or recipients, stratifying our study by DAA era to evaluate potential effect modification.
RESULTS Pre-DAA, for HCV+ recipients, receiving an HCV+ kidney was associated with 1.28-fold higher mortality (HR 1.151.281.42) and 1.22-fold higher death-censored graft failure (HR 1.081.221.39) compared to receiving an HCV- kidney and the absolute risk difference was 3.3% (95%CI: 1.8%-4.7%) for PS and 3.1% (95%CI: 1.2%-5%) for DCGS at 3 years. The HCV dual-infection (donor plus recipient) group had worse PS (0.56-fold) and DCGS (0.71-fold) than the dual-uninfected. Donor HCV+ derived worse post-transplant outcomes than recipient HCV+ (PS 0.36-fold, DCGS 0.34-fold). In the DAA era, the risk associated with HCV+ in donors and/or recipients was no longer statistically significant, except for impaired PS in the dual-infected vs dual-uninfected (0.43-fold).
CONCLUSION Prior to DAA introduction, donor HCV+ negatively influenced kidney transplant outcomes in all recipients, while recipient infection only relatively impaired outcomes for uninfected donors. These adverse effects disappeared with the introduction of DAA.

Kidney transplant from HCV viremic donors to HCV-negative recipients and risk for de novo donor specific antibodies and acute rejection. Clin Transplant 2023; 37:e14895. [PMID: 36580971 DOI: 10.1111/ctr.14895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 12/15/2022] [Accepted: 12/20/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND Kidney transplantation from HCV-viremic donors into uninfected recipients is associated with excellent short-term outcomes. However, concerns regarding an increased risk for the development of de novo donor specific antibodies (DSA) and acute rejection have been raised in single center reports. METHODS A retrospective study of HCV-negative kidney-only transplant recipients between 2018 and 2020. Patients were grouped based on the donor HCV status into group 1; HCV-viremic donors, and group 2; HCV-negative donors. Inverse probability of treatment weighting (IPTW), with weights derived from the propensity score, were used to estimate the effect of donors' HCV-viremia on the recipients. The primary objective was to compare the 1-year incidence of de novo DSA. Secondary outcomes included group comparison of the incidence of biopsy proven acute rejection (BPAR), 1-year patient and allograft survival, and 1-year renal allograft function. RESULTS A total of 71 patients were included in the HCV NAT+ group, and 440 in the HCV- negative group. One-year incidence of de novo DSA was higher in the HCV NAT+ group in the IPTW weighted analysis (19% vs. 9%, p = .02). In the unweighted analysis, BPAR occurred in 7% of recipients in the HCV NAT+ group, compared to 3% in the control group (p = .06). However, due to the low event rate in the in the IPTW weighted groups, a statistical significance test could not be performed. Average estimated GFR was higher in the HCV-viremic group at 3 months (61 vs. 53 ml/min/1.73 m2 p = .002), but comparable at 6 (59 vs. 56 ml/min/1.73 m2 , p = .31) and 12 months (60 vs. 55 ml/min/1.73 m2 , p = .07). Patient and allograft survival were comparable between the two groups. CONCLUSION Kidney transplant from HCV-viremic donors was associated with an increased risk for the development of post-transplant de novo DSA in the first year after transplantation, but no difference in patient and graft survival.

Abstract
PURPOSE OF REVIEW Direct-acting antivirals (DAA) have transformed kidney transplantation by increasing the donor pool from hepatitis C virus (HCV)-infected donors and allowing HCV nucleic acid amplification testing (NAT) donor-positive/recipient-negative (D+/R-) transplantation over the last 7 years. Willingness to accept kidneys from HCV-infected donors and timing/duration of DAA therapy have been evolving. RECENT FINDINGS By 2021, most of the HCV NAT+ kidneys (92.6%) were transplanted to HCV-naive recipients. Despite the availability of effective DAA therapy, the discard rate of HCV NAT kidneys has been stagnant around 25%. The proportion of wait-listed patients willing to accept a deceased donor kidney from HCV Ab+ and HCV NAT+ donors increased 20-fold between 2015 and 2022. Wait-listed time to receive HCV NAT+ kidneys has been rising and most of the kidneys are transplanted to HCV-naive recipients. The proportion of deceased donor kidney transplants performed in recipients with HCV seropositivity decreased from 5.1 to 2.8% during the same period. Relatively short courses of DAA therapy (7-8 days) appear to be effective to decrease HCV transmission (<5%) and achieve sustained virological response at 12 weeks if administered prior to revascularization. SUMMARY Further studies are needed to evaluate long-term outcomes of HCV NAT D+/R- transplantation and the best course of DAA treatment.

Abstract
Background We lack data on the effectiveness of education and the patient's attitude toward different deceased donor kidney types. A prospective study was performed to evaluate patient attitudes, baseline knowledge, and effectiveness of our kidney transplant education process. We also analyzed the knowledge retention of our waitlist patients. Design We prospectively surveyed a patient cohort using a paired analysis pre and post education with initial evaluation visit. Knowledge retention among waitlist patients was assessed with annual waitlist visit. Results One hundred four patients received paired surveys to assess the baseline knowledge and effectiveness of education. Forty-three patients received a single survey with their annual waitlist evaluation to assess knowledge retention. Paired survey showed mixed results, with no statistically significant improvement in the kidney donor profile index domain. Significant improvement was seen in the hepatitis C virus-positive donor domain and the Public Health Service (PHS) increased-risk donor domain. For the waitlist cohort, overall knowledge retention ranged from excellent to fair, with a decline in knowledge for the PHS increased-risk donor domain. Conclusion Our study suggests that the education intervention regarding different deceased donor kidney types is effective overall and transplant candidates retain the knowledge while waiting for transplant.

Abstract
BACKGROUND Donors with hepatitis C virus (HCV) have expanded the donor pool for heart and lung transplantation, but concerns have arisen about rejection. We examined the incidence of rejection after heart and lung transplantation in recipients of HCV-positive donors as well as HCV-positive recipients. METHODS Adults undergoing heart and lung transplantation from March 31, 2015 to December 31, 2019 were identified in the United Network for Organ Sharing/Organ Transplantation and Procurement Network Standard Transplant Analysis and Research file. Patients were stratified as donor-recipient HCV negative, donor positive, and recipient positive. Comparative statistics and a multilevel logistic regression model were used. RESULTS Meeting the criteria were 10 624 heart transplant recipients. Donor-positive recipients were significantly associated with older age, blood group O, and shorter waitlist time. No significant differences existed with regards to treatment for rejection in the first year (negative, 19.5%; donor positive, 22.3%; recipient positive, 19.5%; P = .45) or other outcomes. On regression analysis HCV status was not associated with treated rejection; however center variability was significantly associated with treated rejection (median odds ratio, 2.18). Similarly, 9917 lung transplant recipients were identified. Donor-positive recipients were more commonly White and had obstructive disease and lower lung allocation scores. Both unadjusted (negative, 22.1%; donor positive, 23.0%; recipient positive, 18.6%; P = .43) and adjusted analyses failed to demonstrate a significant association between HCV status and treatment for rejection, whereas center variability remained significantly associated with treatment for rejection (median odds ratio, 2.41). CONCLUSIONS Use of HCV donors has expanded the donor pool for heart and lung transplantation. HCV donor status was not associated with treatment for rejection in the first year, but center variability played a role in the incidence and treatment of rejection.

Abstract
Renal transplant is the most common organ transplant worldwide, accounting for 65% of the total number of transplants. End-stage renal disease (ESRD) often has multiple significant comorbidities. Among the gastrointestinal (GI) disorders, peptic ulcer disease (PUD), cholelithiasis, and colon and liver diseases increase the risk of posttransplant morbidity. Potential renal transplantation (RT) candidates need a multidisciplinary assessment of coexisting illnesses, which may affect the perioperative risk and survival after transplantation. Successful outcome of RT depends on careful selection of the recipients by a thorough medical evaluation and screening. This review summarizes the role of gastroenterologists and hepatologists in preoperative assessment and management of renal transplant recipients.

Abstract
Background: The illicit drug toxicity (overdose) crisis has worsened across Canada, between 2016 and 2021 more than 28 000 individuals have died of drug toxicity. Organ donation from persons who experience drug toxicity death has increased in recent years. Objective: This study examines whether graft loss after kidney transplantation differed by donor cause of death. Design: Retrospective cohort. Setting: Provincial transplant program of British Columbia, Canada. Patients: Transplant recipients who received kidney transplantation from deceased donors aged 12 to 70 years between 2013 and 2019 (N = 1012). Measurements: Transplant recipient all cause graft loss (graft loss due to any cause including death) was compared by donor cause of death from drug toxicity or other. Methods: Five-year Kaplan-Meier estimates of all-cause graft survival, and 3-year complete as well as stratified inverse probability of treatment weighted Cox proportional hazards models were conducted. Results: Drug toxicity death donors donated to 25% (252/1012) of kidney transplantations. Drug toxicity death donors were more likely to be young, white, males, with fewer comorbidities such as diabetes or hypertension but were more likely to have a terminal serum creatinine ≥1.5 mg/dL or be hepatitis C virus (HCV) positive. Unadjusted 5-year estimate of all-cause graft survival was 97% for recipients of drug toxicity donor kidneys and 83% for recipients of non-drug toxicity donor kidneys ( P < .001). Recipients of drug toxicity death donor kidneys had decreased risk of all cause graft loss compared to recipients of non-drug toxicity death donor kidneys (hazard ratio [HR]: 0.30, 95% confidence interval [CI]: 0.12-0.77, P = .012). This is primarily due to the reduced risk of all-cause graft loss for recipients of younger (≤35 years) drug toxicity death donor kidneys (HR: 0.05, 95% CI: 0.00-0.55, P = .015). Limitations: Potential selection bias, potential unmeasured confounding. Conclusions: Donation after drug toxicity death is safe and should be considered more broadly to increase deceased donor kidney donation.

Abstract
Kidney transplantation is the optimal therapy for end-stage kidney disease but limited by the available number of organs. Using HCV+ donors, both in HCV+ and HCV- recipients, is a rational response to the organ shortage. We review the historic experience using HCV+ donors in HCV+ recipients and assess long-term results. We also discuss contemporary practices, including the transplantation of HCV-viremic kidneys into HCV- recipients with different approaches to posttransplant HCV therapy.

Abstract
OBJECTIVES Kidneys from hepatitis C virus-positive donors were often discarded due to the lack of an effective treatment for hepatitis C virus. However, the advent of direct-acting antivirals has facilitated great progress for treatment of hepatitis C virus, providing additional opportunities for patients waiting for kidney transplant. We explored the feasibility and safety of kidney transplant from hepatitis C virus- positive donors to hepatitis C virus-negative recipients in combination with direct-acting antiviral therapy. MATERIALS AND METHODS This was a single-center retrospective study of 7 recipients of hepatitis C virus- positive kidneys from June 2018 to June 2021. All recipients were treated with sofosbuvir/velpatasvir for 12 weeks after kidney transplant. The primary recipients' outcome was achievement of sustained viral eradication at 12 weeks after treatment, and follow-up secondary outcomes were kidney function recovery, liver function, and adverse drug reactions. We reviewed previous studies, from 2017 to 2022, to analyze achievement of sustained viral eradication at 12 weeks after treatment, recipient and graft survival, and adverse event of kidney transplant from a hepatitis C virus-positive donor to a hepatitis C virus-negative recipient. RESULTS Median follow-up time was 71 weeks (range, 56-183 weeks). All recipients achieved sustained viral eradication at 12 weeks after treatment, and their kidney function recovered without severe liver damage or adverse drug reactions. Previous studies suggested that transplant of hepatitis C virus-positive donor kidneys is safe and feasible when combined with direct-acting antiviral therapy. However, details regarding optimal duration of treatment and directacting antiviral regimen remain undetermined, so prospective randomized studies are warranted. CONCLUSIONS Our study further confirms that kidney transplant from hepatitis C virus-positive donors to hepatitis C virus-negative recipients is safe and feasible with direct-acting antiviral treatment. Grafts from hepatitis C virus-infected donors may be effective to resolve the problem of kidney shortage.

Abstract
Hepatitis C virus (HCV) infection is a major health problem with significant clinical and economic burdens in patients with chronic kidney disease (CKD) stage 4 or 5. Current guidelines recommend pan-genotypic direct-acting antivirals (DAAs) to be the first-line treatment of choice for HCV. This review summarizes the updated knowledge regarding the epidemiology, natural history, public health perspectives of HCV in patients with CKD stage 4 or 5, including those on maintenance dialysis, and the performance of pan-genotypic DAAs in these patients. The prevalence and incidence of HCV are much higher in patients with CKD stage 4 or 5 than in the general population. The prognosis is compromised if HCV patients are left untreated regardless of kidney transplantation (KT). Following treatment-induced HCV eradication, patient can improve the health-related outcomes by maintaining a long-term aviremic state. The sustained virologic response (SVR12) rates and safety profiles of pan-genotypic DAAs against HCV are excellent irrespective of KT. No dose adjustment of pan-genotypic DAAs is required across CKD stages. Assessing drug-drug interactions (DDIs) before HCV treatment is vital to secure on-treatment safety. The use of prophylactic or preemptive pan-genotypic DAAs in HCV-negative recipients who receive HCV-positive kidneys has shown promise in shortening KT waiting time, achieving excellent on-treatment efficacy and safety, and maintaining post-KT patient and graft survival. HCV elimination is highly feasible through multifaceted interventions, including mass screening, treatment scale-up, universal precautions, and post-SVR12 reinfection surveillance.

Decision-making Among Hepatitis C Virus-negative Transplant Candidates Offered Organs from Donors with HCV Infection. Transplant Direct 2022; 8:e1341. [PMID: 35923812 PMCID: PMC9298473 DOI: 10.1097/txd.0000000000001341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Accepted: 04/16/2022] [Indexed: 11/26/2022] Open
Abstract
Background Historically, many organs from deceased donors with hepatitis C virus (HCV) were discarded. The advent of highly curative direct-acting antiviral (DAA) therapies motivated transplant centers to conduct trials of transplanting HCV-viremic organs (nucleic acid amplification test positive) into HCV-negative recipients, followed by DAA treatment. However, the factors that influence candidates' decisions regarding acceptance of transplant with HCV-viremic organs are not well understood. Methods To explore patient-level perceptions, influences, and experiences that inform candidate decision-making regarding transplant with organs from HCV-viremic donors, we conducted a qualitative semistructured interview study embedded within 3 clinical trials investigating the safety and efficacy of transplanting lungs and kidneys from HCV-viremic donors into HCV-negative recipients. The study was conducted from June 2019 to March 2021. Results Among 44 HCV-negative patients listed for organ transplant who were approached for enrollment in the applicable clinical trial, 3 approaches to decision-making emerged: positivist, risk analyses, and instinctual response. Perceptions of risk contributed to conceptualizations of factors influencing decisions. Moreover, most participants relied on multiple decision-making approaches, either simultaneously or sequentially. Conclusions Understanding how different decisional models influence patients' choices regarding transplant with organs from HCV-viremic donors may promote shared decision-making among transplant patients and providers.

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

Kidney transplant from hepatitis C viremic donors into aviremic recipients and risk for post-transplant BK and CMV infection. Transpl Infect Dis 2022; 24:e13887. [PMID: 35752929 DOI: 10.1111/tid.13887] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 04/06/2022] [Accepted: 04/16/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND kidney transplantation from HCV-viremic donors to uninfected recipients is associated with excellent short-term outcomes. However, HCV viremia might be associated with an increased risk for post-transplant viral complications. METHODS We designed a retrospective study of HCV-negative kidney-only transplant recipients between 2018 and 2020. Recipients were grouped into group 1; HCV-negative donors, and group 2; HCV-viremic donors. Patients were matched 1:1 using propensity score. Primary objectives were to compare the incidence of CMV viremia ≥ 200 ml/IU, and BK viremia ≥1000 copies/ml between the groups. Secondary outcomes included group comparison of CMV disease, BK viremia ≥10,000 copies/ml, and one year patient and allograft survival. RESULTS The study included 634 patients in group 1, and 71 patients in group 2. 65 pairs of patients were matched. Incidence of CMV viremia (33.3% vs 40.0%, p = 0.4675), and BK viremia (15.9% vs 27.7%, P = 0.1353) did not differ significantly between groups in the matched cohort. Incidence of CMV disease (81.0% Vs 76.9%; p = 1.000), and BK viremia ≥10,000 copies/ml (9.5% vs 16.9%, p = 0.2987) were comparable between groups. There was no difference in the one-year patient or allograft survival between groups. CONCLUSION kidney transplant from HCV-viremic donors is not associated with increased risk for BK or CMV viremia.

Willingness of Kidney and Liver Transplant Candidates to Receive HCV-Infected Organs. J Surg Res 2022; 278:342-349. [PMID: 35667277 DOI: 10.1016/j.jss.2022.05.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 04/13/2022] [Accepted: 05/06/2022] [Indexed: 12/21/2022]
Abstract
INTRODUCTION Transplantation of organs exposed to hepatitis C virus (HCV) into uninfected patients has yielded excellent outcomes and more widespread adoption may lead to fewer discarded organs and more transplants. Patient perceptions may shed light on acceptability and likely the uptake of HCV+/HCV- transplantation, gaps in understanding, and perceived benefits/risks. METHODS We surveyed 435 uninfected kidney and liver transplant candidates at four centers about their attitude towards HCV-infected organs. RESULTS The percentage of patients willing to accept HCV-infected organs increased from 58% at baseline, to 86% following education about HCV, direct-acting antiviral agents (DAAs), and HCV+/HCV- transplantation benefits/risks. More willingness to accept an organ from an intravenous drug user (P < 0.001), age >50 y old (P = 0.02), longer waiting time (P = 0.02), more trust in the transplant system (P = 0.03), and previous awareness of DAAs (P = 0.04) were associated with higher willingness to accept an HCV-infected organ. The most important reasons for accepting an HCV-infected organ were a decrease in waiting time (65%), lower mortality and morbidity risk while on the waiting list (63%), effectiveness of DAAs (54%), and a quicker return to higher functional status (51%). CONCLUSIONS Presenting patients with information about HCV+/HCV- transplantation in small doses that are calibrated to account for varying levels of health and numerical literacy is recommended.

Abstract
BACKGROUND Because of the continued demand in kidney transplantation, organs from donors with risk criteria for blood-borne viruses, high Kidney Donor Profile Index (KDPI) kidneys, and hepatitis C virus (HCV)-positive kidneys are being considered. There continues to be reluctance on the part of the providers and the candidates to accept HCV-positive kidneys. METHODS We conducted a retrospective analysis of the Organ Procurement and Transplantation Network database of all adult (≥18 y old) recipients undergoing kidney transplant from May 10, 2013, to June 30, 2021. We compared patient and graft survival in candidates who received HCV-positive kidneys versus non-hepatitis C (Hep C) high KDPI kidneys by estimated posttransplant survival (EPTS) groups. RESULTS HCV-viremic kidneys were transplanted in 5.6% of patients in the EPTS >61% group compared with 5.1% of patients in the 21%-60% EPTS group and 1.9% of 0%-20% EPTS group (P < 0.001). Of all transplants performed in the EPTS 61%-100% group, 11.9% were KDPI >85% compared with 5.2% in the EPTS 21%-60%, and 0.5% in the EPTS 0%-20%. Patient survival was significantly longer at 1, 3, and 5 y in the EPTS >61% group who received Hep C-viremic or -nonviremic allografts compared with non-Hep C kidneys with KDPI >85%. When it comes to listing, only 25% of candidates in the EPTS >61% group were listed for Hep C nucleic acid testing-positive kidneys in 2021. CONCLUSIONS Our findings could be used for counseling candidates on the types of kidneys they should consider for transplantation. Also, listing practices for viremic Hep C kidneys need continued re-evaluation.

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

Abstract
The use of hepatitis C virus (HCV) -positive organs in HCV-negative recipients with posttransplant antiviral treatment has increasingly been studied since the introduction of new direct-acting antivirals. This article reviews existing experience in liver and kidney transplant. Fifteen studies with 218 HCV D+/R- liver transplants, with 182 from viremic donors, show a sustained viral response for 12 weeks (SVR12) rate of 99.5%. Nine studies involving 204 HCV donor-positive recipient-negative kidney transplant recipients had an SVR12 rate of 99.5%. Complications are infrequent. Preemptive treatment in kidney transplant of for only 4 weeks or even 4 days showed surprising success rates.

Abstract
Chronic hepatitis C virus (HCV) infection is a major global public health problem, particularly in developing part of the world. Significant advances have been made in the early diagnosis and treatment of the disease. Its management has been particularly revolutionized during the past two decades. In this review, we summarize the major advances in the diagnostic and management armamentarium for chronic HCV infection. The focus of the present review is on the newer directly acting anti-viral agents, which have revolutionized the management of chronic HCV infection. Management of uncomplicated chronic HCV infection and of specific complications and special at-risk populations of patients will be covered in detail. Despite the advent and approval of highly effective and well tolerable oral agents, still many challenges remain, particularly the affordability, the equitable distribution and access to later drugs. The World Health Organization aims to eliminate viral hepatitis including HCV by 2030 since its poses a major public health threat. There is an urgent need to ensure uniform and early access to diagnostic and therapeutic facilities throughout the world if the later goal has to be realized.

Abstract
Each hepatitis virus-Hepatitis A, B, C, D, E, and G-poses a distinct scenario to the patient and clinician alike. Since the discovery of each virus, extensive knowledge regarding epidemiology, virologic properties, and the natural clinical and immunologic history of acute and chronic infections has been generated. Basic discoveries about host immunologic responses to acute and chronic viral infections, combined with virologic data, has led to vaccines to prevent Hepatitis A, B, and E and highly efficacious antivirals for Hepatitis B and C. These therapeutic breakthroughs are transforming the fields of hepatology, transplant medicine in general, and public and global health. Most notably, there is even an ambitious global effort to eliminate chronic viral hepatitis within the next decade. While attainable, there are many barriers to this goal that are being actively investigated in basic and clinical labs on the local, national, and international scales. Herein, we discuss pertinent clinical information and recent organizational guidelines for each of the individual hepatitis viruses while also synthesizing this information with the latest research to focus on exciting future directions for each virus.

Abstract
A radical solution is needed for the organ supply crisis, and the domestic pig is a promising organ source. In preparation for a clinical trial of xenotransplantation, we developed an in vivo pre-clinical human model to test safety and feasibility tenets established in animal models. After performance of a novel, prospective compatible crossmatch, we performed bilateral native nephrectomies in a human brain-dead decedent and subsequently transplanted two kidneys from a pig genetically engineered for human xenotransplantation. The decedent was hemodynamically stable through reperfusion, and vascular integrity was maintained despite the exposure of the xenografts to human blood pressure. No hyperacute rejection was observed, and the kidneys remained viable until termination 74 h later. No chimerism or transmission of porcine retroviruses was detected. Longitudinal biopsies revealed thrombotic microangiopathy that did not progress in severity, without evidence of cellular rejection or deposition of antibody or complement proteins. Although the xenografts produced variable amounts of urine, creatinine clearance did not recover. Whether renal recovery was impacted by the milieu of brain death and/or microvascular injury remains unknown. In summary, our study suggests that major barriers to human xenotransplantation have been surmounted and identifies where new knowledge is needed to optimize xenotransplantation outcomes in humans.

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