Focal leukocyte margination is noted in glomeruli and peritubular capillaries, mononuclear with occasional neutrophils. Though difficult to assess, chronic changes are significant (ci2-3, ct2-3). • Immunofluorescence reveals diffuse though mild linear capillary staining for C4d – R/O anti-donor antibody. • The patient had been previously treated with OKT3, and had developed anti-OKT3 antibodies, so he was treated with thymoglobulin. There was poor response to therapy, and the patient returned to dialysis within months with a failed allograft.

However, anti-donor antibody should be sought, to rule out an antibody-mediated component. The quite extensive chronic changes portend a poorer long-term (and in this case short-term!) outcome.

In addition, there was an area in the cortex with O numerous peritubular and intratubular neutrophils, consistent with S bacterial infection. In addition, glomeruli show mild increase in mesangial matrix, with very mild glomerulitis (g0-1). While difficult to I assess, there appear to be mild-to-moderate chronic changes (ci1-2, S ct1-2). • Immunofluorescence studies reveal no C4d staining in peritubular & capillaries. However, there is diffuse granular capillary staining for IgG (2-3+), IgM (trace-1+), C3 (1+) and kappa and lambda light chains (2-3+), and C4d (2-3+).
