Transplant glomerulopathy (TG) is a special form of glomerular injury in renal allografts. It affects varying proportions of glomeruli, which may have an influence on the amount of proteinuria or graft survival. We reviewed 32 cases of TG to evaluate histologic changes and graft outcome. The severity of TG as well as acute and chronic changes of the glomerular, tubulointerstitial and vascular compartment were scored according to Banff classification. There were 17 cases of cg1, 3 cases of cg2 and 12 cases of cg3. There was no significant difference in age, duration of transplant at time of biopsy and duration of follow-up between groups. Serum creatinine level and the degree of proteinuria were higher in cg3 and statistically significant. However, there was no difference in the degree of glomerulosclerosis, inter-stitial inflammation, fibrosis, tubular atrophy or vascular wall thickening between groups. Graft failure was present in 13 cases, mostly due to chronic rejection including sepsis and CMV infection in one case each. Five-year graft survival was 84.1% and was not significantly different from cases without TG. In conclusion, the severity of TG indicates profuse proteinuria, but does not affect graft outcome, which indicates tubulointerstitial and vascular pathology as being a more important prognosticator.
