Insights

Hepatitis C virus (HCV)-viremic kidneys show regional utilization differences in the US. Increased adoption of HCV donor kidney transplants into NAT-negative recipients suggests more equitable access ahead.

Area of Science:

  • Nephrology
  • Transplantation
  • Infectious Diseases

Background:

  • Hepatitis C virus (HCV)-viremic kidneys are increasingly utilized but not universally accepted.
  • Regional disparities and temporal changes in their use require investigation.

Purpose of the Study:

  • To identify and analyze regional variations in the utilization of HCV-viremic kidneys across the United States.
  • To examine temporal trends in HCV-viremic donor kidney transplants into HCV NAT-negative recipients (HCV D+/R- transplants).

Main Methods:

  • Analysis of the Organ Procurement and Transplantation Network database (March 2019-March 2023).
  • Examination of HCV-viremic kidney utilization by US region.
  • Assessment of center-level clustering and distribution of HCV D+/R- transplants using Gini coefficients.

Main Results:

  • Significant regional variations in HCV-viremic kidney utilization were observed, with Regions 3, 10, and 11 accounting for 51% of utilization.
  • Region 9 showed the highest gain (284.9%) from imported HCV-viremic kidneys, while Regions 8 and 6 had the largest net losses (-44.2% and -41.1%).
  • HCV D+/R- transplants were initially concentrated in high-volume centers but showed a trend towards more equitable distribution over time.

Conclusions:

  • Substantial regional disparities exist in HCV-viremic kidney utilization across the US.
  • Transplant centers in certain regions can adopt policies to increase HCV-viremic kidney use and expand their donor pool.
  • Increasing adoption of HCV D+/R- transplants indicates progress towards more balanced access to these kidneys.
