Sickle Cell Program at Smilow Cancer Hospital
Our doctors and nurses work together to provide compassionate, patientdriven care to our patients with sickle cell disease. Patients often suffer from chronic pain and have complicated medical courses due to their sickle cell disease. In collaboration with the Pediatric Stem Cell Transplant Program, we offer bone marrow transplants to patients with sickle cell disease. Our goal is to successfully cure your child’s sickle cell disease through transplant when they are experiencing severe problems due to their sickle cell disease.
What is Sickle Cell Disease?
Sickle cell disease is an inherited blood disease that affects red blood cells. In sickle cell disease, the red blood cells are shaped like sickles, or crescent moons, rather than being round. The sickle-shaped cells can prevent the blood from flowing properly in the body. This variation can affect many organ systems and can lead to severe pain. The risk of developing serious complications in the brain, lungs and heart increases with age.
With specialized medical care, children with sickle cell disease can lead long, healthy lives. Despite newer supportive care, the average life expectancy has remained approximately 20-30 years less than the general population for men and women who are having sickle cell disease.
Role of Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease
Bone Marrow Transplant is the only cure for sickle cell disease at this time. Bone marrow transplants have been used for the treatment and cure of a variety of cancers, immune system diseases, and blood diseases for many years. Through the Pediatric Sickle Cell Program at Smilow Cancer Hospital, children with sickle cell disease are treated with bone marrow transplants and benefit from life-altering, improved outcomes.
Results of many studies show that transplants from matched-related donors offer about an 85 to 90 percent chance of cure. The American Society of Hematology considers transplant a standard of care for patients with sickle cell disease that have an HLA matched sibling donor and have experienced complications such as:
• Multiple pain crisis
• Recurrent acute chest syndrome
• Pulmonary hypertension
• A history of stroke or high-risk for developing stroke
• Developed antibodies to red blood cells
Those patients without a matched sibling donor still have the option of getting a transplant from an unrelated donor or from a parent or half matched sibling. Transplant from a parent or a half matched sibling is called haplo-identical transplant and is currently done under a clinical trial. The Pediatric Sickle Cell Program will work with you to determine if there is an HLA-match within the family, and if not, will work to find an unrelated donor.
What are the Risks of Transplant?
Even though a stem cell transplant is the only cure for sickle cell disease, there are risks. These risks include: infection, graft-versus-host disease (GVHD), effects on liver and kidneys or other organs and long term side effects of infertility. In a small percentage of cases there is a risk of rejection of the transplant if your child’s body does not accept the new cells. Because of our experienced doctors, nurses and staff, along with the use of reduced toxicity transplant therapy to cure sickle cell disease, these risks can be reduced and transplant can be successfully performed
Please contact your sickle cell physician or ask to schedule an appointment with a member of the bone marrow transplant team. Our Pediatric Bone Marrow Transplant coordinator, Cara Keenan, RN, can be reached at 203-200-1609.
