Background:    We investigated the safety and efficacy of Campath induction and tacrolimus (TAC) maintenance therapy compared to ATG induction with TAC +MMF + steroids in de novo kidney-pancreas transplanted patients.
    Material/Methods:    14 patients (Group A) received Campath 30 mg + methylprednisolone 500 mg before revascularization followed by TAC monotherapy, and 16 patients (Group B) ATG 8 mg/kg with TAC + MMF+ steroids (withdrawn at month 3). TAC trough levels (ng/mL) of 12-15 were aimed for in both groups until month 6 and thereafter 6–12.
    Results:    1-year patient survival was 100% in both groups; kidney and pancreas survival in Group A was 93% each. In Group B 1-year kidney and pancreas survival was 100% and 87%, respectively. A total of three pancreas grafts were lost due to thrombosis of the graft vein within the first month. The only kidney loss was due to initial non-function. All biopsy-proven acute rejections of renal transplants (n=3 in Group A, n=0 in Group B) were reversible. No acute pancreas graft rejection was demonstrated. Infectious complications, lipid metabolism and blood pressure were comparable in both groups, as were other adverse events. No tumor occurred. At 12 months 13 patients in each group were steroid-free; the mean serum creatinine level was 1.44 mg/dL in Group A and 1.33 mg/dL in Group B. All patients were exogenous insulin-free.
    Conclusions:    At one year efficacy and safety of Campath +TAC monotherapy were comparable to those of ATG + TAC + MMF + steroids in a limited number of combined kidney-pancreas transplant recipients
