Does sickle cell anemia cause splenomegaly?
Children with sickle cell anemia living in sub-Saharan Africa have an increased risk of having palpable splenomegaly, which is further increased while receiving hydroxyurea treatment. Large spleen at baseline were associated with lower blood counts, consistent with hypersplenism.
Why do sickle cell patients get their spleen removed?
The most common reason for spleen removal among the children was recurrent splenic sequestration crisis, accounting for 92% of the procedures. This condition results as faulty red blood cells clog up the spleen, which can cause a life-threatening blood circulation crisis.
Do sickle cell patients get splenectomy?
Splenectomy is one of the most common procedures required for patients with SCD [9]. The major indications for splenectomy in sickle cell children include splenic sequestration episodes and severe hemolysis secondary to suspected hypersplenism [3, 9-12].
What are symptoms of worsening splenic sequestration?
Minor Splenic Sequestration Mild episodes can cause an enlarged spleen and blood changes such as worsened anemia (low hemoglobin) often a 1-3g/dl decrease from the patient’s baseline hemoglobin, or thrombocytopenia (low platelet count).
What triggers splenic sequestration?
Acute splenic sequestration happens when sickled red blood cells get trapped in the spleen, causing the spleen to enlarge. Sickle cell disease affects the red blood cells causing them to sickle or become banana-shaped. The main purpose of red blood cells (RBCs) is to deliver oxygen to the body.
What happens if splenic sequestration is not treated?
Sickled red blood cells stick together and slow the flow of oxygen to the tissues. When sickled RBCs are trapped in the spleen, the rest of the body does not get enough oxygen. If not treated, acute splenic sequestration can cause the body to go into shock.
How does the sickle cell anemia affect the spleen?
Spleen Crisis (Splenic Sequestration) Sickle cells can block the blood vessels leading out of the spleen. When this happens, blood stays in the spleen instead of flowing through it. This causes the spleen to get bigger, and the blood counts to fall.
How are red blood cells trapped in the spleen?
Sickle cell disease: In sickle cell disease, the sickled red blood cells are not flexible and can be trapped in the spleen, causing the spleen to expand. As more and more red blood cells are trapped in the spleen, it gets larger and larger. This is called splenic sequestration crisis and can cause anemia that may require blood transfusion.
How does sickle cell disease affect the body?
Sickle cell disease affects how children’s bodies make hemoglobin. It’s an important part of red blood cells, which carry oxygen to the rest of the body. These are usually flat, flexible disks. With sickle cell disease, they become stiff and shaped like a crescent, or a sickle.
Where are red blood cells trapped in sickle cell disease?
Blood cells getting trapped in the spleen. The spleen is an organ that is located in the upper left side of the belly. The spleen filters your blood and destroys old blood cells. In people who have sickle cell disease, red blood cells may get trapped in the spleen, making it enlarge quickly.
Why does the spleen enlarge in sickle cell?
Sickle cells can block the blood vessels leading out of the spleen. When this happens, blood stays in the spleen instead of flowing through it. This causes the spleen to get bigger, and the blood counts to fall.
Is sickle cell a curable disease?
Sickle cell anemia is a disease that for the most part cannot be cured. Most people cope with Sickle cell because it is so hard to find a person to help with their cure. A way to cure Sickle cell anemia is to receive a bone marrow transplant to replace the red blood cells.
What is the difference between sickle cell and blood cell?
The key difference between normal red blood cell and sickle cell is that normal red blood cells are round in shape , while sickle cells are distorted red blood cells having a sickle shape. Red blood cells are a major component in our blood. These cells carry oxygen throughout our body. They also transport and remove carbon dioxide from our body.
What is the prognosis for sickle cell disease?
Some people with the disease can remain without symptoms for years, while others do not survive beyond infancy or early childhood. New treatments for sickle cell disease are improving life expectancy and quality of life. People with sickle cell disease can survive beyond their 50s with optimal management of the disease.
