ABSTRACT
BACKGROUND: Dual kidney transplants (DKTs) from expanded criteria donors (ECDs) have been performed in our hospital since 2014. We needed to review our clinical outcome and update criteria to selected ECDs for DKTs. MATERIALS AND METHODS: Between January 2014 and December 2016, 4 DKTs and 269 deceased donor kidney transplants were performed. The outcome of DKTs was reviewed. The literature was reviewed for surgical technique and indication for DKT. RESULTS: Four DKTs were performed between 2014 and 2016. One-year graft survival rate was 100%. One patient developed delayed graft function. No morbidity or mortality occurred. CONCLUSIONS: DKTs in our center were safe and had good outcome with optimized selected criteria. DKT can improve the rate of kidney transplant in a developing country.

BACKGROUND: Sensitization is associated with a high rate of post-transplantation rejection. A desensitization protocol using therapeutic plasma exchange (TPE) was proposed to reduce anti-HLA antibody before transplantation, but there has been limited data regarding the efficacy of pretransplantation TPE in highly sensitized deceased-donor kidney transplantation (DDKT). METHODS: A retrospective cohort study of 142 patients who received DDKT was conducted and divided into two groups: a high-panel-reactive antibody (PRA) >50% group and a low-PRA ≤50% group. The high-PRA group was sub-divided into those who received and did not receive pretransplantation TPE. Donor-specific anti-HLA antibodies (DSA) were also collected pretransplantation in the high-PRA group. RESULTS: The probability of acute rejection was 26, 4, and 9 cases/1000/person month in the high-PRA group with no TPE, the high-PRA group receiving TPE, and the low-PRA group, respectively (P = .0208). In the multivariable logistic regression analysis, the hazard ratio for graft rejection was 2.37 (95% confidence interval: 0.89 to 6.35) and 2.22 (95% confidence interval: 0.54 to 9.13) in the group of high-PRA who received TPE and high-PRA with no TPE, compared with the low-PRA group, respectively (P value not significant). The incidence of antibody-mediated rejection in 6 months in the DSA-positive subgroup was not different between those who received TPE or no TPE. CONCLUSION: Desensitization with TPE is a reasonable alternative for highly sensitized DDKT. Patients who received pretransplantation TPE had a lower incidence of acute rejection compared to the group that did not receive TPE. However, pretransplantation TPE alone was not effective in the prevention of acute rejection in recipients with DSA.
