Does tacrolimus cause more severe anemia than cyclosporine A in children after renal transplantation?
Initial reports indicated the possibility of severe anemia associated with tacrolimus (TC) therapy. We investigated the degree of anemia under TC treatment in comparison to cyclosporine A (CsA) treatment in children after renal transplantation. A cross-sectional analysis of 95 children successfully transplanted for at least 3 months was performed. Eighty-five children received CsA and 10 TC. TC-treated patients were compared with CsA-treated patients who were matched according to age, gender, creatinine clearance, and time after transplantation. No patient received additional therapy with mycophenolate mofetil or azathioprine. The creatinine clearance of the whole group of transplanted children was 58 ml/min per 1.73 m2. The patients within the matched-pair analysis had a lower creatinine clearance (TC 46 and CsA 48 ml/min per 1.73 m2). The hemoglobin was 10.3 g/dl for the TC-treated children and 10.4 g/dl among the CsA-treated patients. Numerically, EPO was higher and iron lower in the TC group than in the CsA group. Among children with functioning renal grafts, a correlation exists between Hb and creatinine clearance. A significant difference in the degree of anemia between TC- and CsA-treated children could not be found.
