The protective role of liver in cross-match(XM) positive SLK recipients and its impact on the incidence of renal antibody mediated rejection (AMR) is unclear.
A retrospective review of data from 9, CDC T/B, Flow XM positive recipients of staged SLK at our center since 2008 was performed. All patients received induction therapy with thymoglobulin + rituximab and maintained on CNI +/- MMF. Four patients underwent desensitization with plasmapheresis x2 sessions prior to kidney transplant. Two received post SLK IVIG and 2 received bortezomib.
We looked at incidence of AMR, serum creatinine and urine protein/creatinine ratio. We compared our findings with the previously published AMR rates in XM positive kidney transplant recipients from our center1. Chi-square without Yates correction with p value<0.05 considered to be significant.
Median follow-up was 635 days. 6 out of 9 patients had >20 months (600 days) follow-up. Two patients died from infection related complications. One patient (11%) had mix rejection AMR+ACR 18 days post-transplant. The mean serum creatinine level at 1 year 0.9 +/- 0.4 mg/dl. The mean urine protein/creatinine ratio at the last follow-up were 0.66 +/- 0.3. Incidence of AMR in XM+ kidney alone patients who underwent desensitization was 31% (19 out of 44), compared to 11% in SLK (p=0.03).

Incidence of renal AMR in highly cross match positive SLK recipients is low compared to cross match positive kidney transplant recipients. Liver appears to have a protective role.
