Increasing Proportion of High-risk Cytomegalovirus Donor-positive/Recipient-negative Serostatus in Solid Organ Transplant Recipients.

Cytomegalovirus (CMV) donor-positive/recipient-negative (D+R-) serostatus is independently associated with worse allograft and patient survival across solid organ transplant (SOT) types. We characterized trends in CMV D+R- serostatus among adult SOT recipients performed in the United States. Donor (D) and recipient (R) CMV serostatus and demographic factors were obtained from the Scientific Registry of Transplant Recipients for persons ≥18 y undergoing a first SOT between January 1, 2000, and December 31, 2020. The proportions of D+R- SOTs over time were assessed using Chi square for trend and modeled through 2040. Factors associated with D/R seropositivity were assessed using logistic models. Among 472 549 SOTs, the average proportion of D+R- SOTs increased significantly among kidney, liver, heart, and lung between 2000 to 2009 and 2010 to 2020: 18.0% to 18.3% ( P  = 0.034), 19.4% to 21.8% ( P  < 0.001), 22.2% to 25.5% ( P  < 0.001), and 23.6% to 27.0% ( P  < 0.001), respectively. The increased proportion over time resulted from a disproportionate increase in R- (34.9% to 37.0% for all organ types, P  < 0.001) and a smaller corresponding change in D+ (60.8% to 60.3%, P  < 0.001). The proportion of high-risk CMV D+R- SOTs increased significantly across all organs and is projected to continue to increase. These findings inform population-level strategies to mitigate the negative impact of CMV D+R- in SOT. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
