Management of Chronic Hepatitis C in End-stage Renal Disease

Treatment for chronic viral hepatitis C has advanced dramatically to current standard of care all-oral direct-acting antiviral regimens with relatively short treatment duration and high efficacy. Patients with comorbid end-stage renal disease have constituted a "special patient population" with data and treatment options lagging behind that of the broader population of patients with chronic hepatitis C until recently. Herein we review the current evidence base for direct-acting antiviral therapy in this population. We provide a suggested algorithm for the evaluation of such patients for therapy. We highlight special considerations in regards to the choice of regimen, duration, and timing in regards to potential kidney transplantation

Drug Authorization for Sofosbuvir/Ledipasvir (Harvoni) for Chronic HCV Infection in a Real-World Cohort: A New Barrier in the HCV Care Cascade.

BACKGROUND:New treatments for hepatitis C (HCV) infection hold great promise for cure, but numerous challenges to diagnosing, establishing care, and receiving therapy exist. There are limited data on insurance authorization for these medications. MATERIALS AND METHODS:We performed a retrospective chart review of patients receiving sofosbuvir/ledipasvir (SOF/LED) from October 11-December 31, 2014 to determine rates and timing of drug authorization. We also determined predictors of approval, and those factors associated with faster decision and approval times. RESULTS:Of 174 patients prescribed HCV therapy during this period, 129 requests were made for SOF/LED, of whom 100 (77.5%) received initial approval, and an additional 17 patients (13.9%) ultimately received approval through the appeals process. Faster approval times were seen in patients with Child-Pugh Class B disease (14.4 vs. 24.7 days, p = 0.048). A higher proportion of patients were initially approved in those with Medicare/Medicaid coverage (92.2% vs. 71.4%, p = 0.002) and those with baseline viral load ≥ 6 million IU/mL (84.1% vs. 62.5%, p = 0.040). Linear regression modeling identified advanced fibrosis, high Model of End Stage Liver Disease (MELD) score, and female gender as significant predictors of shorter decision and approval times. On logistic regression, Medicare/Medicaid coverage (OR 5.96, 95% CI 1.66-21.48) and high viral load (OR 4.52, 95% CI 1.08-19.08) were significant predictors for initial approval. CONCLUSIONS:Early analysis of real-world drug authorization outcomes between October-December 2014 reveals that nearly one in four patients are initially denied access to SOF/LED upon initial prescription, although most patients are eventually approved through appeal, which delays treatment initiation. Having Medicare/Medicaid and advanced liver disease resulted in a higher likelihood of approval as well as earlier decision and approval times. More studies are needed to determine factors resulting in higher likelihood of denial and to evaluate approval rates and times after implementation of restrictive prior authorization guidelines

Living donor liver transplantation: A multi-disciplinary collaboration towards growth, consensus, and a change in culture

INTRODUCTION: Living donor liver transplantation (LDLT) reduces liver transplant waitlist mortality and provides excellent long-term outcomes for persons with end stage liver disease. Yet, utilization of LDLT has been limited in the United States (US). METHODS: In October 2021, the American Society of Transplantation held a consensus conference to identify important barriers to broader expansion of LDLT in the US, including data gaps, and make recommendations for impactful and feasible mitigation strategies to overcome these barriers. Domains addressed encompassed the entirety of the LDLT process. Representation from international centers and living donor kidney transplantation were included for their perspective/experience in addition to members across disciplines within the US liver transplantation community. A modified Delphi approach was employed as the consensus methodology. RESULTS: The predominant theme permeating discussion and polling results centered on culture; the beliefs and behaviors of a group of people perpetuated over time. CONCLUSIONS: Creating a culture of support for LDLT in the US is key for expansion and includes engagement and education of stakeholders across the spectrum of the process of LDLT. A shift from awareness of LDLT to acknowledgement of benefit of LDLT is the primary goal. Propagation of the maxim LDLT is the best option is pivotal

Safety and efficacy of sofosbuvir‐containing regimens in hepatitis C‐infected patients with impaired renal function

Background & aimsRenal clearance is the major elimination pathway for sofosbuvir (SOF). We assessed the safety and efficacy of SOF-containing regimens in patients with varying baseline estimated glomerular filtration rate (eGFR).MethodsHCV-TARGET database is a multicentre, longitudinal 'real-world' treatment cohort.ResultsA total of 1789 patients [genotypes 1 (72%), 2 (17%) 3 (9%), 4-6 (2%)] had baseline eGFR determination: 73 with eGFR≤45 (18 with eGFR≤30, 5 on dialysis) were compared to 1716 with eGFR>45 ml/min/1.73 m(2) . Patients with baseline eGFR≤45 vs. >45 differed in being female (55% vs. 36%), age ≥65 years (24% vs. 16%), Black race (22% vs. 12%), having cirrhosis with decompensation (73% vs. 24%) and being post-transplant (49% vs. 10%), all P < 0.05. All patients with eGFR≤45 were treated with SOF 400 mg/day (including those on haemodialysis) and had median starting ribavirin (RBV) dose of 800 mg (IQR: 400-1200). Sustained virologic response (SVR) frequencies were similar across eGFR groups, ranging from 82-83%. Patients with eGFR ≤45 more frequently experienced anaemia, worsening renal function and serious AEs (all P < 0.05), and these associations persisted when limiting analysis to RBV-free regimens. Patients with baseline eGFR≤30 and eGFR 31-45 had similar frequencies of efficacy and safety outcomes.ConclusionsSustained viral clearance was achieved in 83% of patients with renal impairment (eGFR ≤45 ml/min/1.73 m(2) ) treated with SOF-containing regimens. However, these patients had higher rates of anaemia, worsening renal dysfunction and serious adverse events regardless of use of RBV. Patient with renal impairment require close monitoring and should be treated by providers extensively experienced with SOF-containing regimens

Financial, policy, and ethical barriers to the expansion of living donor liver transplant: Meeting report from a living donor liver transplant consensus conference

Introduction: In October 2021, the American Society of Transplantation (AST) hosted a virtual consensus conference aimed at identifying and addressing barriers to the broader, safe expansion of living donor liver transplantation (LDLT) throughout the United States (US). Methods: A multidisciplinary group of LDLT experts convened to address issues related to financial implications on the donor, transplant center crisis management, regulatory and oversight policies, and ethical considerations by assessing the relative significance of issues in preventing LDLT growth, with proposed strategies to overcome barriers. Results: Living liver donors endure multiple obstacles including financial instability, loss of job security, and potential morbidity. These concerns, along with other center, state, and federal specific policies can be perceived as significant barriers to expanding LDLT. Donor safety is of paramount importance to the transplant community; however, regulatory and oversight policies aimed at ensuring donor safety can be viewed as ambiguous and complicated leading to time-consuming evaluations that may deter donor motivation and program expansion. Conclusion: Transplant programs need to establish appropriate crisis management plans to mitigate potential negative donor outcomes and ensure program viability and stability. Finally, ethical aspects, including informed consent for high-risk recipients and use of non-directed donors, can be perceived as additional barriers to expanding LDLT.</p

A survey of transplant providers regarding attitudes, barriers, and facilitators to living donor liver transplantation in the United States

INTRODUCTION: A successful living donor liver transplant (LDLT) is the culmination of a multifaceted process coordinated among key stakeholders. METHODS: We conducted an electronic survey of US liver transplant (LT) centers (August 26, 2021-October 10, 2021) regarding attitudes, barriers, and facilitators of LDLT to learn how to expand LDLT safely and effectively in preparation for the American Society of Transplantation Living Donor Liver Transplant Consensus Conference. RESULTS: Responses were received from staff at 58 programs (40.1% of US LT centers). There is interest in broadening LDLT (100% of LDLT centers, 66.7% of non-LDLT centers) with high level of agreement that LDLT mitigates donor shortage (93.3% of respondents) and that it should be offered to all suitable candidates (87.5% of respondents), though LDLT was less often endorsed as the best first option (29.5% of respondents). Key barriers at non-LDLT centers were institutional factors and surgical expertise, whereas those at LDLT centers focused on waitlist candidate and donor factors. Heterogeneity in candidate selection for LDLT, candidate reluctance to pursue LDLT, high donor exclusion rate, and disparities in access were important barriers. CONCLUSION: Findings from this study may help guide current and future expansion of LDLT more efficiently in the US. These efforts require clear and cohesive messaging regarding LDLT benefits, engagement of the public community, and dedicated resources to equitably increase LDLT access
