Abstract number: D1716

We studied the impact of pretransplant (pretx) EBV antibody (ab) status on the incidence of PTLD in adult primary kidney tx recipients. Between 1/2002 and 12/2011, 1446 adults with known pretx EBV ab status underwent primary tx (609 DD; 837 LD). All recipients were followed through 9/2012.

Adult EBV-naive (ab negative pretx) recipients were significantly more like to develop PTLD (p<0.0001) (Table 1). New onset PTLD occurred throughout the years of follow-up in the EBV-naive recipients (Table 1). For EBV ab+ recipients, mean age (±SD) at transplant was 51± 13 yrs; for EBV-naive recipients, 45±15 yrs (p.=0.0005). For EBV ab+ recipients, mean age (±SD) at PTLD diagnosis was 57±12; for EBV naive recipients, 56±17 (NS). The risk of PTLD was similar for EBV- naive recipients who received a living or deceased donor kidney (Table 1).

1083 recipients had complete information on donor (D) and recipient (R) EBV status. PTLD-free survival by D/R status is shown in Table 2 (D+/R+; D+R-; D-R+; D-R-). D+/R- transplants were associated with significantly ⇓ PTLD-free survival vs D+/R+ (p=0.008) and D-R- (p=0.01).
