Indeed, a recent study demonstrated the improvement of anemia in mice infected with tuberculosis following the uncombined administration of Fe and EPA/DHA for 3 weeks and a reduction in IL-6 and IL-1 levels [89], both involved in the synthesis of hepcidin [7], even if a direct estimate of hepcidin in mice before and after correction of anemia is lacking. The gene discussed is IL1B; the disease is anemia.
