Promising results for Sickle
Cell recipients a Chemo-Free Stem Cell Transplant. Typical stem-cell transplant treatment
protocols would use chemotherapy and radiation to suppress the bone marrow
before infusing healthy non-sickled cells.
But, chemotherapy & radiation can increase a person’s risk for
infection & other problems.
Types of Stem Cell Transplants:In a typical stem cell transplant for blood disorders very high doses of chemo are used, often along with radiation therapy, to try to destroy all the damaged cells. This treatment also kills the stem cells in the bone marrow. Soon after treatment, stem cells are given to replace those that were destroyed. These stem cells are given into a vein, much like a blood transfusion. Over time they settle in the bone marrow and begin to grow and make healthy blood cells. This process is called engraftment. (American Cancer Association.)
There are 3 basic types of transplants. They are named based on who gives the stem cells.
· Autologous (aw-tahl-uh-gus)—the cells come from you
· Allogeneic (al-o-jen-NEE-ick
or al-o-jen-NAY-ick)—the cells come from a matched related or
unrelated donor
· Syngeneic (sin-jen-NEE-ick
or sin-jen-NAY-ick)—the cells come from your identical twin or
triplet
In a further advance of the NIH procedure,
physicians at UI Health successfully transplanted two patients with cells from
siblings who matched for HLA but had a different blood type.
In all 13 patients, the transplanted cells successfully
took up residence in the marrow and produced healthy red blood cells. One
patient who failed to follow the post-transplant therapy regimen reverted to
the original sickle cell condition.”
To learn more about ongoing
sickle cell transplant trials at NIH (a participant in a trial will not be
charged for a procedure) call 1-800-411-1222 or visit the NIH clinical trials
registry at www.clinicaltrials.gov and
search under ‘sickle cell disease.”
All the best,
