Figure 4. Allograft rejection at De Novo DSA detection and in 1 year.
The prevalence of acute cellular rejection remained similar at 1 year post dnDSA detection, but there was increased acute, active and chronic AMR. The definition of acute, active, AMR was Banff 1) ptc + g score >2 or 2) ptc >0 or g> 0 and C4d >1. Chronic AMR was present if Banff cg score was >0. All patients with chronic AMR had concomitant acute, active AMR. McNemar’s paired analysis was used to compare serial biopsies.
