Hypersplenism is a medical condition that occurs when the spleen becomes overactive and starts removing blood components, such as red and white blood cells and platelets, from the bloodstream too quickly. This can lead to various health issues. In this article, we will explore hypersplenism in simple terms, covering its types, causes, symptoms, diagnostic tests, treatments, and drugs.
Hypersplenism is a disorder of the spleen, the large, gland-like organ in the upper left side of the abdomen that produces red blood cells before birth and, in newborns, removes and destroys aged red blood cells, and plays a role in fighting infection. In the case of Banti syndrome, the spleen rapidly but prematurely destroys blood cells.
This syndrome is characterized by abnormal enlargement of the spleen (splenomegaly) due to obstruction of blood flow in some veins and abnormally increased blood pressure (hypertension) within the veins of the liver (e.g., hepatic or portal veins), or the spleen (splenic veins). The disorder may be due to any number of different factors causing obstruction of portal, hepatic, or splenic veins including abnormalities present at birth (congenital) of such veins, blood clots, or various underlying disorders causing inflammation and obstruction of veins (vascular obstruction) of the liver.
Types of Hypersplenism:
- Primary Hypersplenism: This occurs when the spleen itself is the main problem, causing excessive destruction of blood cells.
- Secondary Hypersplenism: It results from underlying medical conditions like liver diseases or blood disorders that affect the spleen’s function.
Common Causes of Hypersplenism
Banti syndrome may occur due to a number of different factors causing obstruction of, and abnormally increased blood pressure (hypertension) within, certain veins of the spleen (splenic veins) or the liver (e.g., hepatic or portal veins). These may include abnormalities present at birth (congenital) of such veins, blood clots, or various underlying disorders causing inflammation and obstruction of veins (vascular obstruction) of the liver, such as cirrhosis. Increased arsenic intake has also been implicated in some cases. Also, cases have occurred in patients taking long-term azathioprine, particularly after kidney transplantation.
- Liver Cirrhosis: Scarring of the liver can cause hypersplenism.
- Chronic Viral Hepatitis: Infections like hepatitis B and C may lead to hypersplenism.
- Hemolytic Anemia: Conditions where red blood cells break down too quickly.
- Sickle Cell Disease: A genetic disorder affecting red blood cells.
- Thalassemia: An inherited blood disorder that can lead to an overactive spleen.
- Leukemia: A type of cancer that affects white blood cells.
- Lymphoma: Another cancer affecting lymphocytes in the blood.
- Portal Hypertension: Increased blood pressure in the liver can affect the spleen.
- Gaucher Disease: A rare genetic disorder affecting the spleen’s function.
- Myelofibrosis: A bone marrow disorder that can lead to hypersplenism.
- Infectious Diseases: Conditions like malaria or bacterial infections can trigger hypersplenism.
- HIV/AIDS: The virus can affect the immune system and the spleen.
- Autoimmune Disorders: Conditions where the immune system mistakenly attacks the body’s own cells.
- Certain Medications: Some drugs can lead to hypersplenism as a side effect.
- Amyloidosis: A rare condition where abnormal proteins accumulate in tissues.
- Systemic Lupus Erythematosus (SLE): An autoimmune disease that can affect the spleen.
- Rheumatoid Arthritis: An autoimmune disorder that may lead to hypersplenism.
- Alcohol Abuse: Excessive alcohol consumption can harm the liver and spleen.
- Hemochromatosis: An inherited disorder causing iron buildup in organs.
- Kawasaki Disease: A rare childhood illness that may affect the spleen.
Common Symptoms of Hypersplenism
In early stages, symptoms of Banti syndrome include weakness, fatigue, anemia , and abnormal enlargement of the spleen. As the disorder progresses, the anemia becomes more severe. The anemia may be aggravated by a bleeding esophagus that may cause vomiting of blood and the passage of dark stools composed of decomposing blood. Ultimately, in some cases, the liver itself becomes enlarged and subdivided by fibrous tissue (cirrhosis). However, the spleen enlargement in Banti syndrome is the primary symptom.
Patients with Banti syndrome bruise easily, are more likely to contract bacterial infections and carry a fever for longer periods of time.
Symptoms may also include abnormal accumulation of fluid in the abdominal cavity (ascites), weakness, fatigue; abnormally low levels of circulating red blood cells (anemia), white blood cells (leukopenia), and/or platelets (thrombocytopenia), and/or episodes of bleeding (hemorrhage) from the gastrointestinal tract.
- Fatigue: Due to low red blood cell count (anemia).
- Pale Skin: A result of anemia.
- Easy Bruising: Decreased platelet count leads to bleeding.
- Frequent Infections: Reduced white blood cell count weakens the immune system.
- Enlarged Spleen: Visible swelling and discomfort in the abdomen.
- Abdominal Pain: Especially on the left side, where the spleen is located.
- Jaundice: Yellowing of the skin and eyes due to liver involvement.
- Weight Loss: Often due to loss of appetite and malabsorption.
- Swollen Lymph Nodes: Affecting various parts of the body.
- Bone Pain: Common in cases of blood disorders like leukemia.
- Excessive Bleeding: Nosebleeds, gum bleeding, and heavy menstruation.
- Petechiae: Small red or purple spots on the skin.
- Increased Heart Rate: As the body compensates for low blood components.
- Shortness of Breath: Caused by reduced oxygen-carrying capacity of the blood.
- Fever: Common in infections associated with hypersplenism.
- Abdominal Fullness: Feeling bloated or uncomfortable after eating.
- Spider Angiomas: Spider-like blood vessels on the skin.
- Joint Pain: Associated with autoimmune conditions.
- Headaches: Often due to anemia and related oxygen shortage.
- Cognitive Issues: Difficulty concentrating and memory problems.
Diagnostic Tests for Hypersplenism
The diagnosis of Banti syndrome my be confirmed by a thorough clinical evaluation and a variety of specialized tests, particularly advanced imaging techniques such as a splenic venography and magnetic resonance imaging (MRI). During MRI, a magnetic field and radio waves are used to create cross-sectional images of targeted parts of the body.
