ABSTRACT
BACKGROUND:
Anemia is a prevalent condition in heart failure with multiple potential causes. The complex interaction between iron stores, hepcidin, inflammation and anemia is poorly comprehended. We tested the hypothesis that, in stable heart failure patients with anemia, hepcidin is associated with iron deficiency status irrespective of inflammation. METHODS ANDRESULTS:
Stable systolic heart failure outpatients with and without anemia underwent a complete iron panel, erythropoietin, hepcidin and tumor necrosis factor (TNF)-α assessment. Sixty outpatients were studied. Anemic patients (n = 38, mean hemoglobin 11.4 ± 1 g/dl) were older (69.6 ± 9.6 vs. 58 ± 10.8 years old, p < 0.01) compared with nonanemic patients (n = 22, mean hemoglobin 13.8 ± 1.1 g/dl). Iron deficiency was present in 42% of patients with anemia. TNF-α and hepcidin were 29 and 21% higher in patients with anemia, respectively, compared to nonanemic patients; however, no correlations were found between hepcidin and TNF-α levels. Hepcidin levels in the lower tertile (<31.7 ng/ml) were strongly associated with iron deficiency (OR 16.5, 95% CI 2.2-121.2; p < 0.01).CONCLUSION:
In stable heart failure patients with anemia, hepcidin levels may be more importantly regulated by patients' iron stores than by inflammation.
