Sickle cell disease is a group of disorders that cause red blood cells to become misshapen and break down. With the disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis). Infections, pain and fatigue are its symptoms.
What are the advanced treatments for sickle cell disease?
A blood and bone marrow transplant is a potentially curative therapy for some people with the disease. To be successful, transplants require a well-matched donor, usually a close blood relative. Another name for a blood and bone marrow transplant is a hematopoietic stem cell transplant.
What is the permanent cure for sickle cell disease?
A stem cell transplant can cure sickle cell anaemia. Stem cell transplant is recommended only for people, usually children, who have significant symptoms and complications of sickle cell anaemia. The risks associated with the procedure are high and include death.
What is the difference between blood and bone marrow transplants and stem cell transplants?
According to Cancer Research UK, a stem cell transplant uses stem cells from your bloodstream or a donor’s bloodstream. This is also called a peripheral blood stem cell transplant. A bone marrow transplant uses stem cells from your bone marrow or a donor’s bone marrow. Stem cell transplants are the most common type of transplant.
What are the latest advances in the treatment of sickle cell disease?
More recent drugs include voxelotor, which prevents red blood cell sickling, and crizanlizumab, which reduces red blood cell adherence and SCD crises. There are also new drugs in clinical trials.
Other advanced treatments for sickle cell disease (SCD) have evolved significantly. These include:
- Gene Therapy:
- CRISPR-Cas9: This technique is being investigated to edit genes in patients to produce fetal haemoglobin, which can reduce sickling.
- LentiGlobin: A gene therapy that introduces a modified gene to increase the production of fetal haemoglobin.
- Hydroxyurea:
- This medication increases fetal haemoglobin production and reduces the frequency of pain crises and acute chest syndrome.
- Supportive Therapies:
- Regular blood transfusions and pain management strategies are essential components of ongoing care.
- Vaccinations and Antibiotics:
- Preventive measures to reduce the risk of infections, particularly in children.
These treatments can significantly improve the quality of life and outcomes for individuals with the disease. Ongoing research continues to explore new therapies and improve existing ones.
