Long-Term Outcomes of Renal Function After Adult Intestinal Transplantation at a Single Small-Volume Center: 2 Cases of Renal Transplantation.

PURPOSE: Renal dysfunction more frequently occurs after intestinal transplantation (ITx) than after heart, lung, or liver transplantation. We provide a clinical analysis of renal function after adult ITx. METHODS: We retrospectively analyzed 8 adult ITx patients who survived for at least 6 months between 2004 and 2018. Glomerular filtration rate (GFR) measurements were performed at baseline, at 3 and 6 months post-transplantation, and yearly. The median follow-up duration was 53.5 months. RESULTS: All cases were isolated ITx; 3 received living-donor ITx, and 5 received deceased-donor ITx. The mean baseline GFR was 97 mL/min/1.73 m2. The GFR had decreased by more than 50% of baseline at 1 year post-transplant. Renal dysfunction was observed in 4 patients. Two patients developed acute kidney injury due to acute rejection and sepsis. One of these patients fully recovered renal function, but the second patient died. Another 2 patients developed chronic kidney disease and required hemodialysis (HD) within 6 and 3 years, respectively. The first living-donor ITx patient lost renal function progressively over 6 years after ITx. She received a renal graft from the same living donor as for the ITx after 3 years of HD. The other patient (deceased-donor ITx) received a kidney from his daughter at 5 months after HD. CONCLUSIONS: To obtain an accurate assessment of renal function, frequent direct measurements of GFR should be performed to facilitate early diagnosis of renal impairment and to determine subsequent strategies to improve renal function after ITx.

Kidney transplantation using expanded criteria deceased donors with terminal acute kidney injury: a single center experience in Korea.

PURPOSE: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). METHODS: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). RESULTS: The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). CONCLUSION: Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.
