The prevalence of peritubular capillaritis, glomerulitis, and chronic AMR was higher in groups with higher DSA at all time points studied (p<0.01 *Cochran test for trend −DSA/-XM and +DSA groups). The prevalence of peritubular capillaritis, glomerulitis, and chronic AMR was similar in patients with undetected DSA and negative or positive XM. († -DSA/-XM and −DSA/+XM groups p=0.37,p=0.09, and p=0.38 respectively). ** No patients in the −DSA/+XM group had peritubular capillaritis at 5 years.
