Abstract
- BACKGROUND The lack of adequate numbers of kidneys for transplantation has stimulated interest in the use of organs from non-heart-beating donors (NHBDs). The short- and long-term effects of this risk factor on kidney isografts and allografts were examined with a rat model. METHODS NHBDs were killed by ether overdose. Kidney isografts (male Lewis rats [LEW]-->LEW) were transplanted orthotopically into bilaterally nephrectomized recipients 15, 30, 45, and 90 min after asystole to determine short-term survival patterns, which were compared to those of rats bearing kidneys from living donors (LDs, 0 min). Isografts and allografts (Fisher 344 rats-->LEW) from 45-min and 105-min NHBDs and from LD controls were placed in additional recipients in which contralateral native nephrectomy was performed on day 10 to allow the injured graft to recover from its ischemic insult. Serum creatinine, proteinuria, and graft morphology were assessed serially over a 24-week follow-up period. RESULTS Early survival and renal dysfunction of isografted rats correlated with the interval of donor cardiac arrest before transplantation. Long-term survival of recipients of kidneys from LDs and between 45-min and 105-min NHBDs was also significantly different (100% vs. 87% vs. 37% at 24 weeks, respectively, P
