Overview

Hereditary spherocytosis (HS) is a genetic disorder that affects the red blood cells. In people with HS, the red blood cells have an abnormal shape that makes them more likely to be destroyed by the spleen. This leads to a shortage of red blood cells, which can cause anemia, fatigue, and other symptoms. HS is an inherited condition, meaning it is passed down from parents to their children.

If you have a family history of HS, you may want to consider genetic counseling to understand your risk of passing the condition on to your children. It's important to work closely with your healthcare provider to manage your condition and monitor for any potential complications.

 

What is Hereditary Spherocytosis? 

Hereditary spherocytosis is an inherited blood disorder that affects the red blood cells. It is caused by mutations in genes that provide instructions for making proteins involved in the structural integrity of the red blood cell membrane. The red blood cells in people with hereditary spherocytosis are spherical and more fragile than normal, making them more likely to break down prematurely.

As a result, people with hereditary spherocytosis may experience a variety of symptoms related to anemia, including fatigue, weakness, and shortness of breath. They may also have an enlarged spleen, which is the organ responsible for filtering and removing damaged red blood cells from the body.

Hereditary spherocytosis is a genetic disorder, which means that it is passed down from parents to their children. It is typically inherited in an autosomal dominant pattern, which means that a child has a 50% chance of inheriting the condition if one parent has it. However, in some cases, the condition may be inherited in an autosomal recessive pattern.

 

Who is affected by Hereditary Spherocytosis?

Hereditary spherocytosis is a genetic disorder that affects people of all ethnicities and races. It is estimated to occur in approximately 1 in 2,000 to 5,000 individuals in the general population.

The condition is usually diagnosed in childhood, although it can sometimes go undetected until adulthood. In some cases, people with hereditary spherocytosis may not experience any symptoms and may only be diagnosed after a routine blood test.

However, in some cases, the condition may be inherited in an autosomal recessive pattern.

 

What causes Hereditary Spherocytosis?

Hereditary spherocytosis is caused by mutations in one or more genes that provide instructions for making proteins involved in the structural integrity of the red blood cell membrane. These proteins include ankyrin, band 3, and spectrin, among others.

The mutations in these genes cause the red blood cells to become spherical instead of their normal biconcave shape, and to be more fragile and prone to premature destruction. The spleen, which is responsible for filtering and removing damaged or abnormal red blood cells from the body, removes these abnormal red blood cells from circulation faster than normal, leading to anemia and an enlarged spleen.

Hereditary spherocytosis is usually inherited in an autosomal dominant pattern, which means that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition. However, in rare cases, the condition may be inherited in an autosomal recessive pattern, which means that a person must inherit two copies of the mutated gene, one from each parent, to develop the condition.

 

How do healthcare providers diagnose Hereditary spherocytosis?

Healthcare providers use a combination of physical exams, medical history, and laboratory tests to diagnose hereditary spherocytosis. The diagnostic process typically includes the following:

1. Physical examination: The healthcare provider may perform a physical examination to check for signs of anemia and an enlarged spleen.
2. Blood tests: Blood tests can be used to evaluate the number and characteristics of red blood cells. These tests may include a complete blood count (CBC) to look at the number and size of red blood cells, and a reticulocyte count to measure the number of young red blood cells in circulation.
3. Blood smear: A blood smear is a microscopic examination of a thin layer of blood to look for abnormalities in the shape and size of red blood cells.
4. Osmotic fragility test: This test measures the ability of red blood cells to withstand changes in salt concentration. Red blood cells in people with hereditary spherocytosis are more fragile and are more likely to burst in a hypotonic solution.
5. Genetic testing: Genetic testing can confirm the diagnosis of hereditary spherocytosis by identifying mutations in genes associated with the condition.
6. Family history: Family history can be useful in diagnosing hereditary spherocytosis since the condition is inherited.

The diagnosis of hereditary spherocytosis can be challenging, and healthcare providers may use a combination of these tests to confirm the diagnosis.

 

How do healthcare providers treat hereditary spherocytosis?

Hereditary spherocytosis is a genetic disorder that affects the red blood cells, causing them to become spherical in shape and more fragile. Treatment for hereditary spherocytosis focuses on managing symptoms and preventing complications. Here are some of the ways healthcare providers treat hereditary spherocytosis:

1. Folic acid supplements: Folic acid is essential for red blood cell production, and people with hereditary spherocytosis may require higher doses of folic acid to support their red blood cell turnover. Your healthcare provider may recommend folic acid supplements to prevent anemia.
2. Blood transfusions: In severe cases, people with hereditary spherocytosis may require blood transfusions to replace damaged red blood cells.
3. Splenectomy: The spleen is responsible for removing damaged red blood cells from the body. In hereditary spherocytosis, the spleen may be overactive and remove too many healthy red blood cells, leading to anemia. In some cases, a splenectomy (removal of the spleen) may be necessary to prevent anemia and other complications.
4. Supportive care: Healthcare providers may recommend measures to prevent and manage complications associated with hereditary spherocytosis, such as vaccinations to prevent infections, avoiding certain medications that can trigger hemolytic crisis (a sudden breakdown of red blood cells), and avoiding strenuous physical activity that can cause spleen rupture.
5. Genetic counseling: Hereditary spherocytosis is a genetic disorder, which means it can be passed down from parents to children. If you have hereditary spherocytosis or a family history of the condition, genetic counseling can help you understand the risks and options for managing the condition in future generations.

 

How can I prevent Hereditary Spherocytosis?

Hereditary spherocytosis is a genetic condition, which means that it is passed down from parents to their children. It is caused by mutations in genes that control the shape and stability of red blood cells, leading to the formation of spherical-shaped red blood cells that are easily destroyed by the spleen.

Unfortunately, there is no way to prevent hereditary spherocytosis, as it is an inherited condition. However, if you have a family history of hereditary spherocytosis, you may want to consider genetic counseling. This can help you understand your risk of passing the condition on to your children and provide information about possible treatment options.

If you have been diagnosed with hereditary spherocytosis, there are treatments available to manage the symptoms of the condition. These may include blood transfusions, folic acid supplements, and in some cases, surgery to remove the spleen. It is important to work closely with your healthcare provider to develop a personalized treatment plan that meets your individual needs.

 

What are the possible complications of Hereditary spherocytosis (HS)?

Hereditary spherocytosis (HS) is a condition that affects the shape and stability of red blood cells, causing them to become spherical and more easily destroyed by the spleen. The complications of HS can vary from person to person, depending on the severity of the condition. Here are some of the possible complications of hereditary spherocytosis:

1. Anemia: HS can cause anemia, a condition in which there are not enough red blood cells to carry oxygen to the body's tissues.
2. Jaundice: HS can lead to jaundice, a condition in which the skin and whites of the eyes turn yellow due to a buildup of bilirubin, a waste product produced when red blood cells are broken down.
3. Gallstones: HS can increase the risk of developing gallstones, which are small, hard deposits that form in the gallbladder.
4. Enlarged spleen: HS can cause the spleen to become enlarged, which can lead to discomfort or pain in the left upper abdomen.
5. Aplastic crisis: In some cases, HS can cause a sudden and severe drop in red blood cell production, known as an aplastic crisis. This can lead to symptoms such as fatigue, pale skin, and shortness of breath.
6. Pulmonary hypertension: HS can also cause pulmonary hypertension, a condition in which the blood pressure in the lungs is higher than normal, leading to shortness of breath and other symptoms.

 

What do I need to do now that I (or my child) has been diagnosed with HS?

If you or your child has been diagnosed with hereditary spherocytosis (HS), here are some steps you can take:

1. Work closely with a healthcare provider: It's important to work with a healthcare provider who has experience in managing HS. They can help monitor your or your child's condition, provide appropriate treatment, and monitor for potential complications.
2. Develop a treatment plan: Your healthcare provider will work with you to develop a personalized treatment plan based on the severity of your or your child's symptoms. Treatment options may include blood transfusions, folic acid supplements, and in some cases, surgery to remove the spleen.
3. Educate yourself and your family: Learning more about HS can help you better understand the condition and how to manage it. You may want to educate other family members about the condition as well, as HS is a genetic disorder that can be passed down from parents to their children.
4. Monitor for potential complications: HS can lead to complications such as anemia, jaundice, gallstones, an enlarged spleen, aplastic crisis, and pulmonary hypertension. It's important to monitor for these potential complications and work with your healthcare provider to manage them.
5. Stay up-to-date with medical appointments: Regular follow-up appointments with your healthcare provider are important to monitor your or your child's condition and adjust treatment as needed.
6. Consider genetic counseling: If you have a family history of HS or are concerned about passing the condition on to your children, you may want to consider genetic counseling. A genetic counselor can help you understand your risk of passing the condition on to your children and provide information about possible treatment options.
