Compared to the non-TG group, we find that: (1) TG is correlated with high incidences of proteinuria, anaemia and hypoalbuminemia and poorer graft survival; (2) TG is strongly correlated with antibody-mediated microcirculatory injury, especially in cases of glomerulitis and peritubular capillaritis; (3) TG accompanied by HCV infection is a more severe sub-entity and correlates with a poorer graft survival; and (4) TG is associated with a high incidence of IgA deposition in the mesangial area. Here, CD79A is linked to anemia (phenotype).
