Transplantation of HCV Viremic Livers into HCV Viremic Recipients Followed by Direct-acting Antiviral Therapy

Use of Hepatitis C Viremic Donors to Expand the Pediatric Donor Pool

The use of hepatitis C virus (HCV)-positive donors in organ transplantation has become increasingly viable due to advancements in direct-acting antiviral (DAA) therapies, which offer high cure rates. This review aims to evaluate the current practices, benefits, and challenges of utilizing HCV-positive donors for organ transplantation. The recent data show that transplant centers are progressively accepting HCV-positive donors for various organs, including kidneys, livers, and hearts, given the efficacy of post-transplant antiviral treatment. Using these donors has helped mitigate the organ shortage crisis, increasing the donor pool and reducing waitlist times. Despite these advantages, the approach raises concerns about viral transmission, long-term outcomes, and the cost-effectiveness of post-transplant DAA therapy. Furthermore, this review highlights the ethical implications of informed consent and the monitoring of HCV-negative recipients following transplantation. The outcomes from recent studies suggest that with proper management, transplantations from HCV-positive donors to HCV-negative recipients can be safe and effective, leading to excellent graft function and patient survival. This review synthesizes existing research and offers insights into optimizing protocols for future transplants involving HCV-positive donors.

The current status of virus-positive liver transplantation

PURPOSE OF REVIEW

The last 2 years have seen significant developments in virus-positive liver transplantation. This review provides an updated account of the transplantation of hepatitis C virus (HCV), hepatitis B virus (HBV) and HIV-positive livers, with a specific focus on studies published in the last 18 months.

RECENT FINDINGS

The advent of highly efficacious direct acting antiviral agents, nucleos(t)ide analogues and a continued organ shortage have led to the well tolerated utilization of HCV, HBV and HIV-positive organs. There has been a significant increase in the transplantation of HCV seropositive and NAT+ organs into HCV-negative recipients, without compromising patient or graft survival. Early reports of HBV core antibody (HBVcAb), HBV surface antigen (HBVsAg) positive and NAT+ donors are growing in the USA with promising results. Similarly, small studies have described the use of HIV-positive to HIV-positive liver transplantation without concerns for superinfection.

SUMMARY

HCV, HBV and HIV-positive liver transplantations can be accomplished safely and are associated with equivalent outcomes when paired with appropriate recipients. The practice of virus positive liver transplantation should be encouraged to combat the ongoing organ shortage.

Direct-Acting Antivirals and Organ Transplantation: Is There Anything We Can't Do?

The opioid epidemic has resulted in an increase in organ donors with hepatitis C virus (HCV) infection in the United States. With the development of direct-acting antiviral regimens that offer high sustained virologic response rates even in the setting of immunosuppression after transplantation, these HCV-viremic organs are now being offered to transplant candidates with or without preexisting HCV infection. Strategies for HCV treatment with HCV-viremic organs have included delayed and preemptive approaches. This review will discuss key studies in the different solid organ transplants, recent reports of adverse events, and ethical and regulatory considerations. The efficacy of current HCV therapies has created this important opportunity to improve survival for patients with end-organ failure through greater access to organ transplantation and decreased waitlist mortality rate.
