Background and objectives Two recent studies reported increased risk of ESRD after kidney donation. In both, the majority of ESRD was seen in those donating to a relative. Confounding this observation is that, in the absence of donation, relatives of those with ESRD are at increased risk for ESRD. Understanding the pathogenesis and risk factors for postdonation ESRD is critical for both donor selection and counseling. Design, setting, participants, & measurements We hypothesized that if familial relationship was an important consideration in pathogenesis, the donor and linked recipient would share ESRD etiology. We obtained information from the Organ Procurement and Transplantation Network (OPTN) on all living kidney donors subsequently waitlisted for a kidney transplant in the United States between January 1, 1996 and November 30, 2015, to determine (1) the donor–recipient relationship and (2) whether related donor–recipient pairs had similar causes of ESRD. Results We found that a significant amount of information, potentially available at the time of listing, was not reported to the OPTN. Of 441 kidney donors listed for transplant, only 169 had information allowing determination of interval from donation to listing, and only 99 (22% of the total) had information on the donor– recipient relationship and ESRD etiology. Of the 99 donors, 87 were related to their recipient. Strikingly, of the 87, only a minority (23%) of donor–recipient pairs shared ESRD etiology. Excluding hypertension, only 8% shared etiology. Conclusions A better understanding of ESRD in donors requires complete and detailed data collection, as well as a method to capture all ESRD end points. This study highlights the absence of critical information that is urgently needed to provide a meaningful understanding of ESRD after kidney donation. We found that of living related donors listed for transplant, where both donor and recipient cause of ESRD is recorded, only a minority share ESRD etiology with their recipient.
