RESUMO
BACKGROUND: Anemia frequently occurs after kidney transplantation, its origin is multifactorial. The objective of this study was to evaluate the frequency of anemia among kidney transplantation patients at 3 months after transplantation and its relationship to inflammatory, oxidative, and nutritional states. Furthermore, we determined serum prohepcidin, a precursor of hepcidin, the main hormone implicated in iron metabolism. MATERIALS AND METHODS: We performed a transverse retrospective study in 130 patients who underwent kidney transplantation, including 89 men and 41 women. Patients were randomized according to the presence or absence of anemia at 3 months. The patients' inflammatory, oxidative, and nutritional states were evaluated as well as renal function and serum prohepcidin at 3 months. RESULTS: Twenty-four percent of the patients developed anemia at 3 months after transplantation. These patients presented with a greater inflammatory state, a poor nutritional status, and poor renal function. Serum prohepcidin was significantly lower compared with the transplantation patients who did not show anemia. CONCLUSIONS: Serum prohepcidin was significantly higher among kidney transplantation patients who did not develop anemia. The inflammatory state may be a determinant of the response to treatment with erythropoiesis-stimulating agents in anemic kidney transplant recipients.
