Purpose: Significant variation in maintenance immunosuppression (mIS) regimens has been described between transplant centers for simultaneous liver kidney (SLK) transplant recipients; we sought to describe this variation and explore the post-transplant outcomes associated with various regimens.
Methods: We studied 6262 adult SLK recipients using Scientific Registry of Transplant Recipients data from Mar 2002 – Feb 2017. We characterized mIS regimens at discharge and at one year post-transplant. We evaluated the association between regimen at 1 year and mortality and graft failure using Cox proportional hazard models, adjusting for patient and donor-specific characteristics.
Results: Triple therapy consisting of tacrolimus, steroids, and an antimetabolite was the most common initial regimen, but the proportion of patients on this regimen decreased over time in favor of steroid-sparing regimens. At 1 year, 90% of patients were on a tacrolimus based regimen. Compared to triple therapy, use of a steroid sparing tacrolimus and antimetabolite regimen at 1 year was associated with a 25% decreased risk of patient mortality (aHR: 0.75; 95% CI: 0.62-0.91, p = 0.003) without increased risk of kidney or liver graft failure. Use of a tacrolimus and steroid combination regimen had an increased risk of mortality compared to triple therapy, though not statistically significant (aHR 1.21, 95% CI: 0.99-1.48, p = 0.07).
Conclusions: Though nearly 70% of SLK recipients are placed on triple maintenance immunosuppression therapy initially, there is considerable variation in how immunosuppression is managed thereafter. Many patients transition to a steroid-sparing regimen with improved mortality without compromising graft loss.
