What is Sickle Cell Disease?

Sickle Cell Anemia, a genetic blood condition, results in excruciating pain and sometimes fatal consequences. Red blood cells change into a sickle shape and become lodged in blood arteries. The illness disproportionately affects persons of African and Hispanic/ Caribbean ancestry but the trait has also been found in those with Middle Eastern, Indian, Latin American, Native American and Mediterranean heritage. It has been estimated that 1 in 3 people in the United States are affected by the disease and millions worldwide suffer complications from sickle cell disease. It is present in one out of every 500 African-American births and over 3 million African Americans or one out of 12 have the sickle cell trait.

 

Sickle Cell Disease can take many different forms. The most common are:

 

  • Hemoglobin SS Disease (Anemia)

  • Hemoglobin SC Disease (Trait)

  • Sickle Beta-Plus Thalassemia

  • Sickle Beta-Zero Thalassemia

 

The majority of people with sickle cell disease have Hemoglobin S, but some also produce hemoglobin C, D, or E, which are other types of defective hemoglobin. Individuals can have Sickle Cell Disease because of co-inheritance of Beta Thalassemia.

 

Historically there has not been much investment in researching the causes and treatment of SCD. There is little understanding about the relationship between SCD and pain and there have been few advancements in finding better treatments for the disease. Sickle Cell Warriors of Wisconsin promotes basic and translational research and supports initiatives to increase community participation in clinical research. Basic and clinical research efforts are important to expanding knowledge of the pathophysiology of SCD and to ensure smooth transition of scientific advances into clinical trials.

Disease-Modifying Medications

L-glutamine (Endari)

Approved by the FDA in 2017, Endari is an oral medication that consists of L-glutamine, an amino acid. It helps reduce oxidative stress in sickled red blood cells.

Crizanlizumab (Adakveo)

Also approved in 2019, Adakveo is a monoclonal antibody that binds to a protein called P-selectin on the surface of endothelial cells and platelets, reducing the adhesion of sickled cells to blood vessel walls.

Drug and Syringe

Voxelotor (Oxbryta)

Approved in 2019, Oxbryta is a medication that directly targets the hemoglobin in red blood cells to inhibit polymerization, the process that leads to sickling.

Hydroxyurea Treatment

Hydroxyurea is one of the first disease-modifying therapies approved for SCD. It works by stimulating the production of fetal hemoglobin (HbF), which can reduce the formation of sickle-shaped red blood cells.

Revolutionizing Treatment with Gene Therapy

Recent advancements in gene therapy and gene editing offer unprecedented hope for individuals living with Sickle Cell Disease (SCD). These innovative approaches aim to address the root cause of SCD—the genetic mutation in the hemoglobin beta (HBB) gene—by repairing or modifying the patient's own stem cells to produce healthy red blood cells. This section explores how these cutting-edge therapies work and their potential to transform lives.

Bone Marrow and Stem Cell Transplants

A Potential Cure for Sickle Cell Disease

​

Bone marrow and stem cell transplantation offer a promising path toward curing Sickle Cell Disease (SCD). By replacing diseased stem cells with healthy ones, the body can produce normal red blood cells, alleviating symptoms and complications.

​

How It Works:

​

  • Hematopoietic Stem Cell Transplantation (HSCT):

    • Procedure: Diseased bone marrow is replaced with healthy stem cells from a donor.

    • Donor Matching: Best results with a fully matched sibling donor; newer methods allow for partial matches, expanding donor options.

​

Benefits:

​

  • Potential Cure: Eliminates the underlying cause of SCD.

  • Improved Quality of Life: Reduces or eliminates pain crises and other complications.

 

Risks and Considerations:

​

  • Graft-Versus-Host Disease (GVHD): Donor cells may attack the recipient's body.

  • Infection Risk: Weakened immunity during treatment increases susceptibility.

  • Eligibility: Not suitable for everyone; depends on age, health, and donor availability.

 

Advancements:

​

  • Reduced-Intensity Conditioning: Lower chemotherapy doses reduce side effects.

  • Expanded Donor Options: Partial matches (haploidentical transplants) increase eligibility.

 

Next Steps:

​

  • Consult a Specialist: Talk to a hematologist or transplant center about suitability.

  • Support Resources: Access our programs for guidance and assistance.

 

Note: Bone marrow and stem cell transplants involve significant risks. Decisions should be made in consultation with medical professionals.

Pain Management Strategies

Managing Pain in Sickle Cell Disease

​

Pain crises are a common and challenging aspect of Sickle Cell Disease (SCD). Effective pain management is essential to improve quality of life and overall well-being.

​

Approaches to Pain Management:

​

  • Medications:​

    • Prescription Opioids: For moderate to severe pain under medical supervision.

    • Hydroxyurea: Reduces the frequency of pain episodes by increasing fetal hemoglobin.

  • Over-the-Counter Analgesics: For mild pain relief (e.g., acetaminophen, ibuprofen).

  • Non-Medication Therapies:

    • Hydration: Adequate fluid intake helps prevent sickling of red blood cells.

    • Heat Therapy: Warm baths or heating pads can alleviate pain.

    • Physical Therapy: Exercises to maintain joint flexibility and muscle strength.

    • Relaxation Techniques: Deep breathing, meditation, and mindfulness to reduce stress-induced pain.

  • Psychological Support:

    • Counseling: Helps cope with chronic pain and emotional challenges.

    • Support Groups: Connecting with others who understand your experience.

 

Working with Healthcare Providers:

​

  • Individualized Pain Plan: Develop a personalized strategy with your medical team.

  • Regular Monitoring: Adjust treatments as needed for effectiveness and safety.

  • Education: Learn about pain triggers and management techniques.

 

Note: Always consult a healthcare professional before starting or changing pain management strategies.
