Previous literature suggests that the recurrence of focal segmental glomerulosclerosis (FSGS) after renal transplantation is more common in recipients who have received an HLA-identical living-related (LRD) transplant. To address the question if FSGS patients can safely receive a 6-antigen match LRD kidney transplant, we analyzed death-censored renal allograft survival data of FSGS patients from the United States Renal Data System database (USRDS). Using the USRDS and the U.S. Scientific Renal Transplant Registry between the years 1988-97, we found 19259 adult primary renal transplant recipients, of which 2414 patients had FSGS as their primary diagnosis as compared to 16845 patients who had other types of glomerulonephritis (GN). A Cox proportional hazard model was used to estimate death-censored graft survival among FSGS patients with a zero mismatch LRD kidney transplant. The model included a triple interaction term comparing FSGS vs. GN vs. living donation (LD) vs. cadaveric donation (CAD) vs. zero mismatch (six antigen or HLA-identical) vs. mismatch. Annually adjusted death censored graft loss rates per 1000 patients (ADGL) were calculated. Focal segmental glomerulosclerosis patients receiving a zero mismatch LRD kidney transplant had the lowest ADGL rate, losing 10.5 grafts per 1000 patients per year. Not significantly different but higher (14.3) was the ADGL rate for LD, zero mismatch GN recipients. The ADGL rate was significantly higher in FSGS recipients who received a LD, mismatched transplant (36.5). Focal segmental glomerulosclerosis patients who received a CAD, zero mismatched graft (44.1), or CAD, mismatched graft (63.2), had significantly higher ADGL rates. Zero mismatch LRD kidney transplants are not a risk factor for graft loss in FSGS patients but are associated with significantly better death-censored graft survival as compared to CAD 6-antigen match or mismatched donations.
