Pre-transplant anti-angiotensin II type-1 receptor antibody (ATRAb) levels in Kidney Transplant Recipients (KTR): Pre-transplant ATRAb levels were quantitated in 145 KTR; 44 KTR who suffered rejection episodes; 14 KTR with Antibody Mediated Rejection (AMR) and 4 KTR in this group also had concurrent CMR, 30 KTR with Cellular Mediated Rejection (CMR) and 7 KTR subclinical borderline rejection, and 94 KTR with no rejection episodes. Those 14 KTR with AMR had a greater number of ATRab U/ml than the 94 KTR with no rejection (Po0.01) using Kruskal-Wallis analysis.
