Why does hypersplenism cause leukopenia?
These findings indicated that MΦs are involved in hypersplenism. In the measurement of splenic size by ultrasonography and radionuclide studies, Shah et al (9) demonstrated that splenic phagocytic activity in cirrhosis increased as the spleen enlarged, which contributed to anemia and leukopenia.
What happens to erythrocytes in hypersplenism?
When your spleen’s overactive, or “hyper,” it removes too many blood cells, including healthy ones. Without enough healthy, mature blood cells, your body has a harder time fighting infections and you may become anemic.
Why does leukemia cause splenomegaly?
Splenomegaly can also occur as a result of certain blood cancers, such as leukemias and lymphomas. In these diseases, cancer cells can infiltrate the spleen and lead to enlargement. Additionally, splenomegaly can result from portal hypertension which refers to increased blood pressure in the portal vein.
Is splenomegaly common in leukemia?
Splenomegaly is the most common physical finding in patients with chronic myelogenous leukemia (CML). In more than 50% of the patients with CML, the spleen extends more than 5 cm below the left costal margin at time of discovery.
How is hypersplenism diagnosed?
The term hypersplenism describes some of the sequelae that are often observed with splenomegaly. Criteria for a diagnosis of hypersplenism include anemia, leukopenia, thrombocytopenia, or combinations thereof, plus cellular bone marrow, splenomegaly, and improvement after splenectomy.
What is the causes of hypersplenism?
Common causes of hypersplenism include: Cirrhosis (advanced liver disease) Lymphoma. Malaria.
Why does cirrhosis cause hypersplenism?
Hypersplenism is a common complication in patients with chronic liver diseases, leading to decreases in platelet and hemoglobin levels, and correlates with the severity of cirrhosis. Splenomegaly is often used radiologically as an indicator of cirrhosis….Hypersplenism in Patients With Liver Cirrhosis and Portal Hypertension.

Does hypersplenism cause thrombocytopenia?
Increased splenic platelet pooling is the primary cause of the thrombocytopenia of hypersplenism. In patients with hypersplenism, as much as 90% of the total platelet mass can be found in the spleen. In hypersplenism, the platelet count is usually 50,000-150,000/µL.
What cancers cause splenomegaly?
Both non-Hodgkin and Hodgkin lymphomas are associated with splenomegaly. Both acute and chronic leukemias as well as the subtype hairy cell leukemia are associated with splenomegaly.
Why does lymphoma cause splenomegaly?
They may be primary, arising from the spleen, or secondary, involving the spleen as part of systemic dissemination of a lymphoma that arises elsewhere. As a general rule, isolated presentation with splenomegaly is more common in indolent lymphoma than in aggressive lymphoma.
What are the symptoms of hypersplenism?
- Pain or fullness in the left upper belly that can spread to the left shoulder.
- A feeling of fullness without eating or after eating a small amount because the spleen is pressing on your stomach.
- Low red blood cells (anemia)
- Frequent infections.
- Bleeding easily.
What is the difference between splenomegaly and hypersplenism?
Splenomegaly refers strictly to spleen enlargement, and is distinct from hypersplenism, which connotes overactive function by a spleen of any size.
