ABSTRACT

Objective:

To evaluate the effect of preoperative panel reactive antibody(PRA)levels on long-term survival after kidney transplantation.

Methods:

Data on 1 162 patients underwent first kidney transplantation performed between January 2001 and June 2014 were included in our center. According to the preoperative PRA levels,the patients were divided into negative group( PRA≤10%) and positive group( PRA>10%) ,which were retrospectively analyzed.

Results:

The 1-,5-,10-year patient survival rates of the negative group calculated by Kaplan-Meier were 96. 8%,89. 4%,78. 6%,respectively,while the positive group were 93. 5%,81. 6%, 65. 4%. The 1-,5-,10 -year death-censored graft survival rates of the negative group were 95. 9%,84. 8%,63. 1%,respectively,while the positive group were 92. 3%,74. 1%,51. 9%. The log-rank test revealed that there was significant difference between the patient and graft survival curves (χ2 =9. 623/11. 019, P=0. 002/0. 001 ) . Cox multivariate analysis found that preoperative PRA levels were independent risk factors for reducing the patient or graft survival rates(P<0. 001). Logistic multivariate regression analysis confirmed the significant association between preoperative PRA levels and the risk of acute rejection ( OR=8. 25,95% CI=2. 86-5. 72, P<0. 001). The 5-,10-year creatinine values were significantly lower in the negative group compared to the positive group(all P<0. 05), while there was no difference in the 1-year. In addition, Logistic multivariate regression analysis confirmed the significant association between preoperative PRA levels and the production of donor specific antibody(DSA)(OR=6. 89,95% CI=4. 52-9. 17,P<0. 05).

Conclusion:

The detection of preoperative PRA is an important indictor predicting the sensitivity status of the recipients. The preoperative PRA positive recipients need careful monitoring and diagnosis of acute rejection and DSA after kidney transplantation.
