ObjectiveAnemia, a common multifactorial problem in kidney transplant recipients, represents an important cardiovascular risk factor. The purpose of this study was to assess anemia prevalence after kidney transplantation, the main factors involved in its occurence, its cardiovascular consequences, and its impact on patient survival and graft function.MethodsThis retrospective study evaluated 69 patients undergoing renal transplantation between January 1998 and September 2008 with ≥1 year of follow-up. For all of the patients, we recorded hemoglobin concentrations before and at 1, 3, 6, 12, 36, and 60 months after transplantation. Anemia was defined as recommended by the American Society of Transplantation: hemoglobin level <12 g/dL in women and <13 g/dL in men. To determine the factors involved in anemia occurrence, we compared 2 groups of patients, with versus without anemia, at various times after renal transplantation.ResultsThis study showed a high prevalence of anemia in the early posttransplantation period of 82.7% and 42% of kidney transplantation patients at 1 month and 6 months, respectively. It was mainly related to a low pretransplant hemoglobin level. The prevalence declined to 37.7% at 1 year. Renal graft dysfunction was the most important factor in the occurrence of late post–renal transplantation anemia. The presence of anemia increased the risk of renal graft functional deterioration by a factor of 2.9. The decreased prevalence at 1 year after transplantation was significantly associated with a reduction in left ventricular hypertrophy.ConclusionThe management of anemia is essential to improve renal graft survival, reduce cardiovascular morbidity, and ensure a better quality of life for renal transplant recipients.
