Acanthocytosis: Causes, Symptoms, Diagnosis, Treatment, and Management

Acanthocytosis is a term that refers to distinct morphological changes on the surface of red blood cells. It can be a sign of certain medical conditions or diseases and therefore, this term can be used in many different contexts. Acanthocytosis can affect the function of red blood cells due to the abnormal shape of these cells and can lead to anemia in some cases. Treating the underlying disease that causes acanthocytosis can help improve acanthocytosis and reduce symptoms. Therefore, it is important to identify the underlying cause of acanthocytosis and implement appropriate treatment strategies. Treatment may vary depending on the patient’s condition and the cause, so it is important to consult a healthcare professional.

Causes of Acanthocytosis

Acanthocytosis can occur due to several different reasons:

Genetic Mutations: Some types of acanthocytosis are caused by inherited mutations.

Hemoglobinopathies: Diseases with abnormal structure of hemoglobin molecules can lead to abnormal shape changes in red blood cells.

Hemolytic Anemias: Hemolytic anemias can cause morphological changes in red blood cells and acanthocytosis.

Liver Diseases: Liver diseases can disrupt the normal function of red blood cells and cause acanthocytosis.

Medications: Some medications can affect the structure of red blood cells and cause acanthocytosis.

Symptoms of Acanthocytosis

Some underlying causes and symptoms that can lead to acanthocytosis include:

Sickle Cell Anemia:

  • tiredness
  • pallor, jaundice
  • pain similar to needle pricks
  • chest pain
  • shortness of breath
  • stroke

Hereditary Acanthocytosis:

  • hepatosplenomegaly
  • neurological symptoms
  • cardiomyopathy

Other Hemolytic Anemias:

  • pallor
  • tiredness
  • jaundice
  • dark urine
  • abdominal pain

Liver Diseases:

  • enlarged liver
  • jaundice
  • abdominal pain

Diagnosis of Acanthocytosis

Acanthocytosis is related to morphological changes in red blood cells and diagnosis is usually made through laboratory tests and clinical evaluation:

Clinical Evaluation: The doctor evaluates the patient’s symptoms and medical history.

Complete Blood Count: CBC evaluates the number, size, and shape of red blood cells.

Peripheral Smear: Red blood cells’ shape and structure are observed by examining a blood sample under a microscope.

Hemoglobin Electrophoresis: This test can detect different types of hemoglobin molecules and diagnose hemoglobinopathies.

Reticulocyte Count: Reticulocytes represent newly produced red blood cells.

Genetic Tests: Genetic tests can be used if a genetic mutation causing acanthocytosis is suspected.

Review of Medications: If medications are considered as a cause of acanthocytosis, examining the medications the patient is taking and evaluating whether the medication is causing these symptoms is important.

Investigation of Underlying Causes: Additional tests and imaging studies may be performed to diagnose the underlying disease causing acanthocytosis.

Treatment of Acanthocytosis

Acanthocytosis is treated based on the underlying cause or disease:

Sickle Cell Anemia: The treatment of sickle cell anemia focuses on relieving symptoms and preventing crises:

  • folate supplements
  • pain relievers for managing crises
  • medications like hydroxyurea
  • blood transfusion
  • antibiotics

Hereditary Acanthocytosis: There is no specific treatment for hereditary acanthocytosis as it is a genetic disorder.

Other Hemolytic Anemias: Treatment of hemolytic anemias can vary depending on the underlying causes.

Liver Diseases: Treatment for liver diseases causing acanthocytosis is determined based on the underlying liver disease.

Review of Medications: If medications are suspected to cause acanthocytosis, reviewing the medications and evaluating alternative treatment options is important.

Management of Acanthocytosis

Management of acanthocytosis should focus on the underlying cause or disease:

Management of Sickle Cell Anemia: Medications like hydroxyurea can help reduce the frequency of crises. It is important to take the medications recommended by the doctor regularly.

Management of Hereditary Acanthocytosis: There is no specific treatment for hereditary acanthocytosis as it is a genetic disorder.

Management of Other Hemolytic Anemias: Management of hemolytic anemias can vary depending on the underlying causes.

Liver Diseases: Treatment for liver diseases causing acanthocytosis is determined based on the underlying liver disease.

Review of Medications: If medications are suspected to cause acanthocytosis, reviewing the medications and evaluating alternative treatment options is important.

Healthy Lifestyle: Adopting a healthy lifestyle is important to improve overall health and help manage symptoms.
