Early renal functional adaptation was examined in 81 haploidentical donor and recipient pairs, as well as long-term stability of glomerular filtration rate (GFR) in 78 recipients. GFR was determined pre- and 1 month postnephrectomy in donors and 1 month post-transplant and yearly thereafter in recipients. Compensatory increase in filtration (CIF) of transplanted and native kidneys was calculated using donor pretransplant GFR: [CIF= (GFR at 1 month/donor prenephrectomy GFR) × 100]. Annual rates of change in GFR were estimated using within-patient linear regression analysis (slopes). Recipients without rejection (n = 62) and their donors had similar early GFR and CIF. Those with acute rejection (n = 19) had significantly lower GFR and CIF than their donors (61 ± 16 mL/min/1.73m2 and 57 ± 14% vs. 75 ± 11 and 69 ± 9; p = 0.01 and p < 0.001). Recipients without cyclosporine (n = 52) had 1 month GFR and CIF of 70 ± 14 and 67 ± 14 vs. 72 ± 11 and 69 ± 11 for their donors. Those with cyclosporine (n = 29) had 1 month GFR and CIF of 64 ± 14 and 62 ± 16 vs. 69 ± 12 and 67 ± 11 for their donors (p = 0.15 and 0.16). Comparison of median (25th, 75th) rates of change of GFR with and without acute rejection or cyclosporine did not demonstrate significant effects of either on stability of allograft function, although there was a trend towards greater loss of GFR in cyclosporine-treated patients [- 1.1 (-2.5, 0.8) vs. 0.0 (-1.8, 1.2) mL/min/1.73 m2/year, p = 0.47]. We conclude that, in the absence of rejection, the transplanted kidney maintains the same capacity for functional adaptation as its native partner. Therapy with cyclosporine does not significantly inhibit early physiological adaptation of renal transplants.
