Hepatitis C Virus Donor Positive Kidney Transplantation for Hepatitis C Virus Negative Recipients

Traditionally, HCV+ kidneys are not offered to HCV- patients on the waiting list. The primary concern with offering HCV+ kidneys to HCV- recipients is a risk of viral transmission. Although data about the long-term impact of HCV+ kidney transplantation in to HCV- recipients is unclear, there was a clear suggestion of an increased risk of liver disease in these patients based upon studies performed in the 1990s. Traditional therapy with Interferon could not be offered to these patients as it can lead of rejection if kidney transplant. It was recently reported that nearly 65% (out of a total 6546) of all HCV+ kidneys were discarded between the years 2005-2014. These kidneys were otherwise of excellent quality and could have benefitted more than 4000 patients with 12,000 plus years of graft life.

Since the recent FDA approval of Direct Acting Anti-virals (DAA), these drugs have now been shown to be safe and efficacious even in the setting of kidney transplant. They could offer a unique opportunity to expand the kidney donor pool. For this study, the investigators hypothesize that pre-emptive treatment with a direct acting anti-viral HCV medication to cure HCV soon after transplant would allow for safe transplantation of HCV+ kidneys in disadvantaged and needy HCV- kidney recipients with acceptable risks and improved survivals compared with historical cohorts. This novel study will develop pilot data on the safety and efficacy of utilizing HCV+ kidneys in high-risk HCV- recipients in order to expand the donor pool and reduce the morbidity and mortality of hemodialysis.
