Predictive factors of postrenal transplant anemia.
OBJECTIVE
The aim of our study was to identify independent factors that might predict anemia at 6 months' (M6) and 12 (M12) months' posttransplantation. Postrenal transplant anemia was defined as a hemoglobin (Hb) level below 13 g/dL for men, and below 12 g/dL for women. We included 99 renal transplants performed in our department in 2001, for whom the graft was still functioning at 1 year.


RESULTS
Anemia was observed in 78%, 35.5%, and 25% on day (D) 0, and at M6, and M12, respectively. Iron deficiency was observed in 14% of patients at D0, and 13% at M12. During the postoperative period, 59.8% of patients received at least one blood transfusion, whereas 37% of patients were prescribed recombinant erythropoietin (rEpo) therapy within the first few months posttransplantation. By multivariate analysis the independent predictive factors for anemia at M6 were rEpo therapy at D0, initial nephropathy, posttransplantation rEpo therapy, hematocrit at M3, platelets at D7 and sirolimus therapy. The independent predictive factors for anemia at M12 were rEpo therapy at D0 and platelets at D7, delayed graft function (DGF), serum creatinine, and creatinine clearance at M12, and Hb level at M6 were also checked.


CONCLUSIONS
The prevalence of anemia is 25% at M12; DGF, renal function at M12, and anemia at M6 were independent risk factors of anemia at M12.
