Need for Pretransplant Midodrine Does Not Negatively Impact Simultaneous Liver-kidney Transplant Outcomes.

BACKGROUND: Midodrine is often needed pretransplant to improve hemodynamics in simultaneous liver-kidney transplant candidates. Previous research has shown that patients requiring midodrine before kidney transplant alone have increased posttransplant risk for delayed allograft function, graft failure, and death. However, the impact of pretransplant midodrine use on outcomes after simultaneous liver-kidney transplant is unknown. METHODS: We performed a retrospective study of all adult (age ≥18 y) simultaneous liver-kidney transplant recipients from a single academic transplant center from February 1, 2002, to June 30, 2019. RESULTS: Sixty-four simultaneous liver-kidney transplants were performed in our institution during this time period, of which, 43 were not on midodrine before transplant, 17 were on midodrine alone, and 4 were on intravenous (IV) vasopressor therapy. Despite the midodrine group having a higher MELD-Na at listing, higher MELD-Na at transplant, and being older, there were no significant differences in key outcomes including delayed renal allograft function, estimated glomerular filtration rate at transplant discharge, and estimated glomerular filtration rate at 1 y after transplant compared with the nonmidodrine group. There was no significant difference in graft failure or survival at last follow-up. CONCLUSIONS: Our study suggests that need for pretransplant midodrine should not be a barrier to simultaneous liver-kidney transplant.
