Pathophysiology of anemia of chronic inflammation

Increased inflammatory cytokines effect Consequences on erythropoiesis
Increased macrophage activation
  • Increased erythrophagocytosis

  • Decreased RBC survival

Suppressed erythroid precursor differentiation Fewer RBC
Decreased erythropoietin responsiveness Fewer erythroid precursors
Decreased erythropoietin production Fewer erythroid precursors
Increased circulating hepcidin concentration
  • Macrophage iron sequestration

  • Hypoferremia

  • Iron-restricted erythropoiesis
