Living donor kidney transplantation: impact of differentiated immunosuppressive regimen.Wolters HH, Heidenreich S, Dame C, Brockmann JG, Senninger N, Krieglstein CF Department of General Surgery, University of Münster, Münster, Germany. wolterh@uni-muenster.de INTRODUCTION: Recipients of related (R) and unrelated (NR) living donor kidney transplantations (LDKTX) receive immunosuppressive (IS) therapy 5 days in advance in order to achieve low rates of acute rejection episodes. We herein report the different IS regimens for R and NR transplants as well as acute rejection and primary function rates. METHODS: Ninety-five LDKTX (69% R, 31% NR) were performed with mean cold ischemia time (CIT) of 145 +/- 32 minutes. In R-LDKTX mean age of recipients was 31 +/- 12.5 years. This cohort included 41 men and 25 women whose mean age was 50 +/- 11.1 years. The therapeutic regimen for R-LDKTX included CyA/MMF/prednisone; for NR-LDKTX, FK/MMF/prednisone. Among the recipients of NR grafts the mean recipient age was 51 +/- 8.5 years. This cohort included 23 men and 6 women whose donor mean age was 50 +/- 8.8 years. The mean HLA mismatch among R-LDKTX (2.3) was significantly less than that in the NR-LDKTX cohort (3.51). RESULTS: At a mean follow-up of 35 months, 94.7% of grafts were functioning. DGF was seen in only one recipient (1%). Three grafts were lost due to acute (R) or chronic (NR) rejection or to multiorgan failures. Two recipients died with functioning grafts. Biopsy-proven rejection episodes were observed in 17.2% of NR-LDKTX and 9% of R-LDKTX. In R-LDKTX 50% of rejection episodes were corticoid-sensitive, while 33% needed ATG, and 16% were treated by a switch to FK. In NR-LDKTX 20% of rejections were corticoid-sensitive, 40% needed ATG, and 40% were treated with rapamycin rescue therapy. CONCLUSION: Although HLA mismatching is significantly different between R- and NR-LDKTX, no difference in outcome was observed, which may be due to the specific therapeutic regimen and short CIT.
