What is the pathologic mechanism involved in aplastic anemia?

Aplastic anemia (AA) is characterized by bone marrow (BM) hypocellularity, resulting in peripheral cytopenias. An antigen-driven and likely auto-immune dysregulated T-cell homeostasis results in hematopoietic stem cell injury, which ultimately leads to the pathogenesis of the acquired form of this disease.

What are the characteristic features of aplastic anemia?

Aplastic anemia is a condition that occurs when your body stops producing enough new blood cells. The condition leaves you fatigued and more prone to infections and uncontrolled bleeding. A rare and serious condition, aplastic anemia can develop at any age.

What is the classification of aplastic anemia?

Aplastic anemia is classified as non-severe (NSAA), severe (SAA) and very severe based on the degree of the peripheral blood cytopenias (Box 1).

Does aplastic anemia go away?

How Is It Treated? If your doctor can identify the cause of your aplastic anemia and get rid of that trigger, the condition may go away. But doctors can rarely pinpoint the exact cause. If your case isn’t severe, you may not need treatment unless or until your blood count drops below a certain level.

Can aplastic anemia turn into leukemia?

Individuals affected with acquired aplastic anemia are also at risk that it will evolve into another similar disorder known as myelodysplasia. In a minority of cases, acquired aplastic anemia may eventually develop leukemia.

Can you live a full life with aplastic anemia?

Aplastic anemia is a life-threatening condition with very high death rates (about 70% within 1 year) if untreated. The overall five-year survival rate is about 80% for patients under age 20. In recent years, the long-term outcomes of aplastic anemia patients have been continuously improving.

Can aplastic anemia go into remission?

Spontaneous remission was rapid and complete in most patients, and relapses were rarely observed. In most cases with spontaneous remission, aplastic anemia might be associated with external factors such as drug or infection.

Is there a cure or treatment for aplastic anemia?

Although not a cure for aplastic anemia, blood transfusions can control bleeding and relieve symptoms by providing blood cells your bone marrow isn’t producing.

How to know if you have aplastic anemia?

Key points about aplastic anemia 1 Aplastic anemia occurs when your bone marrow doesn’t make enough red and white blood cells, and platelets. 2 This condition can make you feel tired, raise your risk of infections, and make you bruise or bleed more easily. 3 To treat the low blood counts, early treatment involves easing symptoms.

What causes hemoglobin to drop in aplastic anemia?

Aplastic anemia occurs when your bone marrow doesn’t make enough red and white blood cells, and platelets. Having fewer red blood cells causes hemoglobin to drop.

How are blood transfusions used to treat aplastic anemia?

Blood transfusions aren’t a cure for aplastic anemia. But they do relieve signs and symptoms by providing blood cells that your bone marrow isn’t producing. A transfusion may include: Red blood cells. Transfusions of red blood cells raise red blood cell counts. This helps relieve anemia and fatigue.
