*Purpose: There is limited data on outcomes for patients receiving a isolated kidney transplant (KAIT) after any prior Multi-organ or Isolated Intestinal transplant (IT). We compared the outcomes of such transplants with Combined Intestinal-Kidney Transplants (CIKT).
*Methods: The KT database from 1992 through Sep 2017 was cross-linked with the IT database for all kidney transplants performed. Data was analyzed for incidence, demographics, risk factors and outcomes after KT.
*Results: There were a total of 2,886 IT recorded from 1990 through Sep 2017. There were a total of 190 (6.6%) Kidney transplants recorded of which 54 (28.4%) were KAIT while the remaining 136 (71.6%) where Combined (CIKT). The Median Duration from Intestinal Transplant to Kidney transplant was 5.6 years (Range 0.47 to 18.9).One year KAIT graft survival was 87% as compared to CIKT 52%. 5 year graft survival was 74% vs 36%. Death censored KAIT graft survival at 1 year was 98% vs 87% and 5 years 83% vs 74%.overall unadjusted kidney graft survival was significantly lower in CIKT as compared to KAIT p=0.009.
| Variable | Total N=190 | KAIT 54 | CIKT 136 |
| Adult/Peds (%) | 62.1/37.9 | 57.4/42.6 | 64/36 |
| Recipient age at Transplant | 32 +/-21 | 34+/-20.7 | 31+/-22.1 |
| Kidney transplant adult/peds (%) | 66.9/33.1 | 74.1/25.9 | |
| Wait time | 158+/-279 | 268+/-361 | 117 +/-230 |
| Females | 48.4 % | 57.1% | 47.1% |
| whites | 78.4% | 79.6% | 77.9% |
| Kidney rejectin within 1 year | 7.4% | 11.1% | 5.9% |
NEW ERA 2007-2017 UNDAJUSTED GRAFT OVERALL SURVIVAL
| 1YR | 3YR | 5YR | 10YR | |
| KAIT N=30 | 93% | 85% | 64% | 64% |
| CIKT N=95 | 56% | 40% | 34% | 34% |
*Conclusions: Our data shows that isolated kidney transplant after any prior Multi-organ or isolated Intestinal transplant has higher graft survival as compared to combined Intestinal Kidney Transplant. Higher CNI tough levels may be one common factor leading to lower graft survival.
