Sickle Cell Disease and Thalassemia
Dr. Lakshmanan Krishnamurti’s clinical research is focused on developing newer, gentler types of bone marrow transplantation for patients with inherited blood disorders, such as sickle cell disease and Thalassemia. Most often, stem cell transplantation is used to treat cancer. However, BMT is the only procedure that can cure sickle cell disease, a blood disorder affecting more than 50,000 Americans.
Children with sickle cell disease have crescent-shaped, sticky, rigid red blood cells that obstruct blood flow and decrease the amount of oxygen reaching their organs, which causes frequent pain crises. Eventual outcomes include organ shutdown and, on average, a 30-year loss of life expectancy. Approximately 60 BMTs for sickle cell disease have been performed in the United States in the last 10 years because the stringent criteria and stigma of BMT - that it is an intensive treatment requiring weeks of hospitalization - kept patients away.
To increase the number of sickle cell patients undergoing BMT, the procedure had to be made safer and less toxic. Researchers, such as Dr. Krishnamurti, have learned that BMT becomes less toxic when large doses of immunosuppressive medications are given before transplant, instead of high doses of chemotherapy. This reduced intensity conditioning reduces many of the risks and side effects associated with BMT.
Dr. Krishnamurti performed the first successful BMT using such a reduced intensity conditioning regimen on an 8-year old girl with sickle cell disease. Ultimately, it is hoped that such reduced intensity conditioning regimens will make BMT available to many more patients with sickle cell disease and Thalassemia.
