Methods of analysis for peritubular capillaritis and glomerulitis in acute renal rejection: capillaritis in management of routine diagnosis

Peritubular capillaritis in the renal allograft takes center stage

Capillaritis in the renal allograft is important for diagnosis and prognosis. Although glomerulitis has been well studied, peritubular capillaritis has been defined only relatively recently. The finding that peritubular capillaritis severity score and extent may correlate independently with graft outcome mandates further prospective studies to confirm this finding, and to enhance recognition and quantitation of this important lesion.
