BACKGROUND: Although endogenous erythropoietin secretion returns via the renal allograft a few hours following successful engraftment, anemia is a common early or late complication. In addition, anemia is a risk factor for ischemic heart disease and graft loss. We sought to determine risk factors for and the prevalence of severe anemia immediately posttransplantation (PTA).
METHODS: This cross-sectional retrospective study performed between 2006 and 2009 enrolled 864 adult subjects of mean age 40.7±13.8 (range=6-75) years. On the basis of The World Health Organization criteria, a hemoglobin (Hb) level less than 11 g/dL for men and less than 10 g/dL for women was defined as severe anemia.
RESULTS: Severe anemia occurred frequently (62.7%) among these patients whose most common underlying disease was hypertension 311 (58.2%). Their mean Hb level was 9.9±1.8 g/dL at the time of hospital discharge, namely, almost 2 weeks after transplantation. More than 90% (n=778) of subjects received a kidney from a living donor. Immediate severe anemia associated with delayed graft function (DGF; P=.01), antithymocyte globulin (ATG)/antilymphocyte globulin (ALG) administration (P=.000), acute rejection (P=.000), recipient gender (P=.000), cold ischemic time (P=.01), pretransplant Hb (P=.000), posttransplant creatinine (P=.001), and acute rejection episodes (P=.000). Upon logistic regression analysis donor age (P=.04, confidence interval [CI]=0.7-0.9), recipient female gender (P=.009, CI=0.08-0.7), and ATG/ALG use (P=.009, CI=1.7-43.4) showed significant effects to cause severe PTA.
CONCLUSION: Immediate anemia after renal transplantation is a consequence of poor renal function. In addition, ATG/ALG use and DGF can induce severe PTA, which may play roles in ischemic heart disease and graft loss.
