Anemia of chronic disease is associated with which conditions?

Anemia of chronic disease arises from inflammation driving changes in iron metabolism and erythropoiesis. Inflammatory cytokines—especially IL-6—stimulate the liver to produce hepcidin, which lowers iron release from macrophages and decreases intestinal iron absorption. This leaves iron unavailable for red blood cell production even when iron stores are adequate, and it also blunts the bone marrow’s response to erythropoietin. That pattern is most commonly seen with chronic inflammatory or autoimmune conditions, such as SLE or inflammatory bowel disease like ulcerative colitis, making those inflammatory states the classic association. COPD can involve chronic inflammation, but the hallmark associations in exams are inflammatory diseases. Iron deficiency represents a separate mechanism with low ferritin and low iron, while malnutrition can lead to various anemias but does not define the typical inflammatory pattern seen in anemia of chronic disease.
