BACKGROUND. The benefits (e.g., low acute rejection [AR] rate) vs. the long-term risk of each immunosuppressive protocol may determine the protocol's value. METHODS. We studied the long-term impact of new-onset posttransplant diabetes (PTDM) and/or AR in 1,487 adult, primary transplant, nondiabetic recipients. Per Cox regression, donor source, AR, and PTDM were independent risk factors for graft loss (each, p<.0001). Recipients were subdivided by donor source and into these 4 groups: no AR, no PTDM [n=857]; no AR, PTDM [n=134]; ≥1 AR, no PTDM [n=403]; ≥1 AR, PTDM [n=93]. RESULTS. There was a significant difference between groups in 15-yr actuarial graft survival (GS) and death-censored (DC) GS (p<.0001). Importantly, ≥1 AR had more impact on 15-yr GS and DC GS than did PTDM; the worst outcome was for those having both AR and PTDM. In separate analyses, we censored those with >1 AR; and then only compared those developing AR or PTDM in the first year. The results were similar-the AR (no PTDM) group did worse than the PTDM (no AR) group (p<.001). CONCLUSIONS. Determining long-term risks associated with immunosuppressive protocols is important for treating future patients. Our data suggests that 15-year actuarial outcome (GS and DC GS) is worse for those developing AR than for those developing PTDM.
