Anemia of chronic disease
Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia.
Anemia of chronic disease (ACD) is anemia that is found in people with certain long-term (chronic) medical conditions that involve inflammation.
Anemia of inflammation; Inflammatory anemia; AOCD; ACD
Anemia is a lower-than-normal number of red blood cells in the blood. ACD is a common cause of anemia. Some conditions that can lead to ACD include:
- Autoimmune disorders, such as Crohn disease, systemic lupus erythematosus, rheumatoid arthritis, and ulcerative colitis
- Cancer, including lymphoma and Hodgkin disease
- Long-term infections, such as bacterial endocarditis, osteomyelitis (bone infection), HIV/AIDS, hepatitis B or hepatitis C
Anemia of chronic disease is often mild. You may not notice any symptoms.
When symptoms occur, they may include:
- Feeling weak or tired
- Shortness of breath
Exams and Tests
The doctor will perform a physical exam.
Anemia may be the first symptom of a serious illness, so finding its cause is very important.
Tests that may be done to diagnose anemia or rule out other causes include:
- Hemoglobin level
- Red blood count
- Reticulocyte count
- Serum ferritin level
- Serum iron level
- Other blood tests
Anemia is often mild enough that it does not need treatment. It will likely get better when the disease that is causing it is treated.
The condition is rarely severe enough to need a blood transfusion.
The anemia will improve when the disease that is causing it is treated.
Discomfort from symptoms is the main complication in most cases. Anemia may lead to a higher risk for death in people with heart failure.
