BACKGROUND: The aim of this prospective randomized study was to examine the effect of induction immunosuppression and low initial cyclosporine (CsA) on the onset of graft function and its long-term consequences. METHODS:During 1999-2001, 155 patients were randomized to single 9 mg/kg dose antithymocyte globulin (ATG)-Fresenius (group A) or two 20-mg doses of basiliximab (group B) with reduced dose CsA or conventional CsA triple therapy without induction (group C). RESULTS:Delayed function (DGF) was lower in group A than in groups B or C (5.7% vs. 24.1% and 15.9%, P<0.025) and need of dialysis was less in groups A and B compared to C (10.3 and 10.4 vs. 20.0 days, P<0.05). Acute rejections occurred in 11.3%, 12.1% and 20.5%, and the mean (median) time to rejection was 16 (13), 97 (46) and 101 (35) days in groups A, B, and C, respectively (P<0.005). One-and 5-year graft survivals (GS) were 98.1% and 90.6% (group A), 96.6% and 96.6% (group B), and 93.2% and 84.1% (group C). Five-year GS was significantly better in group B than in group C (P<0.05). The death censored 5-year GS in groups A, B, and C were 94.3%, 96.6%, and 90.0% (P=NS). Single high-dose ATG induction was associated with hemodynamic and pulmonary disturbances without, however, serious or long-term consequences. CONCLUSIONS: ATG induction significantly reduced DGF. Both induction regimens together with low initial CsA led to significantly less posttransplant dialysis and excellent survival. The high dose ATG was associated with significant hemodynamic and pulmonary side effects during drug infusion.
