The average concentration of hepcidin in anemic UC patients was 0.656 ± 0.321 ng/mL and was significantly lower compared to UC patients without anemia (0.945 ± 0.449 ng/mL; p = 0.042) and the control group (1.016 ± 0.400 ng/mL; p < 0,001). This evidence concerns the gene HAMP and anemia (phenotype).
