Toxoplasma antibody positive donors (TPD) constitute one such group. The objective of our study was to compare graft survival in deceased donor renal transplant (Tx) recipients, stratified by Toxoplasma IgG status, using the Organ Procurement and Transplantation Network (OPTN) database. A log-linear event history regression model for graft failure categorized by Toxoplasma IgG status, adjusting for confounders was applied to recipients of 1 st kidney only Tx from 2018-2022. Of the 51422 Tx, 4317 (8.4%) were from TPD. Acute rejection and graft failure (5% each) were similar among groups.The crude graft failure was 7.3 failures per 100 person-years for TPD recipients compared to 6.5 failures per 100 person-years for the Toxoplasma negative group (p 0.008). The crude failure rate ratio was 1.14 with the adjusted hazard rate ratio of 1.04 (95% CI: 0.94, 1.15, p 0.39). In renal Tx recipients, TPD graft recipients have comparable survival to Tx from Toxoplasma negative recipients. While caution must still be taken and close monitoring of recipients undertaken post-Tx for surveillance of disseminated toxoplasmosis, our study suggests that patients can be successfully managed using organs from TPD.
