Abstract

Background and objectives: Intestinal transplants carry a high morbidity/mortality. Kidney allograft outcomes after combined intestinal (IT) with kidney transplant (CIKT) remain largely uninvestigated. Materials and methods: The UNOS STAR database was queried to identify all such combined organ transplants from 2000 to 2015. Results: Out of a total 2215 (51.4% peds vs 48.6% adults) intestinal transplants, 111 (5.0%) CIKT were identified (32.4% peds vs 67.6% adults). Over the study period of CIKT, a total of 45.9% of these cases died with a functioning kidney graft. DGF rate was 9.0%. The 1-year reported kidney acute rejection rate was 6.3%. For the entire CIKT population over the entire study era, the 1-, 3-, and 5-year unadjusted kidney graft survival was 57%, 39%, and 34%, while death-censored kidney graft survival was 93%, 90%, and 86%, respectively. Overall conditional 5-year kidney graft survival (defined as 1-year kidney graft survival) was 58%. Overall, patient survival was significantly lower in recipients of CIKT compared to intestinal transplant (IT) (P <.005); However, the 5-year conditional (1 year kidney graft) patient survival in adults was not significantly different between IT and CIKT overall (P =.194). Conclusions: Kidney allograft survival is primarily dependent on 1-year patient survival. Guidelines regarding allocation of kidney allografts in CIKT need to take into consideration utility and urgency.
