We sought to determine the prevalence and predictive factors for posttransplant anemia within the first year after orthotopic liver transplant (OLT) among 97 consecutive patients. Anemia was defined at months 6 and 12 according to the WHO criteria, that is, a hemoglobin (Hb) level of <12 g/dL for women and <13 g/dL for men. Immunosuppression relied on tacrolimus and steroids, with or without mycophenolate mofetil. Anemia was present in 64.5%, 50%, and 52.8% of patients pre-OLT versus 6 and 12. Thirty-three percent (month 6) and 30.3% (month 12) of anemic patients received recombinant erythropoietin therapy. A multivariate analysis revealed that the independent predictive factors for anemia at month 6 were mean corpuscular volume (<85 fL) at day 7, daily steroid dosage (<0.3 mg/kg), serum creatinine (>130 mumol/L), and Hb level (<11 g/dL) at month 1. Independent predictive factors for anemia at month 12 were daily steroid dosage at month 1 (<0.3 mg/kg), hematocrit at month 1 (<33%), red blood cell count at month 6 (<3.75 T/L), daily dosage at month 1 of cyclosporine or tacrolimus, and etiology of end-stage liver disease other than alcohol abuse. We concluded that anemia was highly prevalent within the first year of post-OLT. This observation deserves further investigation and appropriate treatment.
