To evaluate the prevalence of anemia and appraise its risk factors at 6 months after renal transplantation.


This retrospective study was performed between 2008 and 2010 in 2713 adult kidney transplant recipients to determine the prevalence of posttransplantation anemia. Anemia was defined as hemoglobin concentration of 12 g/dL or less in women and 13 g/dL or less in men.


The prevalence of posttransplantation anemia was 52.7%, with severe anemia (hemoglobin‚ȧ11 g/dL) detected in 24.4% of patients. Impaired renal function was the only risk factor associated with anemia (odds ratio, 3.6; P=.047). However, severe anemia after kidney transplantation was correlated with female sex (P=.001), renal allograft dysfunction (P=.00), and cytomegalovirus infection (P=.002).


The present study demonstrated a quite high prevalence of posttransplantation anemia, in particular associated with impaired renal allograft function. Severe anemia was correlated with female sex, degree of kidney graft dysfunction, and cytomegalovirus infection.
