Anemia of inflammation has been described as usually mild, presenting with erythrocytes of normal size (normocytic) and Hb content (normochromic), decreased serum iron but replete iron stores (ferritin > 100 mg/L), elevation of inflammatory markers (CRP, IL-6), and elevated hepcidin [94,122]. This evidence concerns the gene GSTM1 and anemia (phenotype).
