Every year, thousands of adults and children need bone marrow transplants -- a procedure which may be their only chance for survival. Although some patients with aplastic anemia, leukemia or other cancers have a genetically matched family member who can donate, about 70 percent do not. These patients' lives depend on finding an unrelated individual with a compatible tissue type -- often within their own ethnic group -- who is willing to donate marrow.
Since 1987, the National Marrow Donor Program (NMDP) has facilitated more than 4,000 unrelated marrow transplants. There is a critical need for more volunteer donors. Many patients, especially people of color, cannot find a compatible donor among those on the registry. Patients and donors must have matching tissue types, and these matches are found most often between people of the same ethnic group. A large, ethnically diverse group of prospective donors will give more patients a chance for survival.
Marrow is the tissue found inside bones that produces red blood cells, white blood cells and platelets. These vital blood cells fight infection, carry oxygen and help control bleeding. Any disease that attacks the bone marrow can eliminate the body's ability to protect itself.
If you are in good health and between the ages of 18 and 60, you may be eligible to join the NMDP's registry, where patients seeking a compatible donor begin their search.
- Volunteers who wish to join the registry complete a questionnaire, and then a small sample of blood is drawn and your inherited tissue type (HLA, or human leukocyte antigen type) is determined.
- The laboratory results are entered into the NMDP's registry, a computerized database of potential donors.
- If you match the tissue type of a patient seeking a donor, additional testing will confirm the results. You will meet with marrow donor counselors at the Blood Center who will help you make an informed decision about donating marrow.
- The marrow collection process usually does not require an overnight stay in the hospital. The procedure itself is painless, because it is performed under anesthesia. But, for an average of two weeks following the procedure, most donors experience sore hips and some must restrict their activities. Most donors also report that donating marrow is a very positive experience. Many marrow donors are willing to donate again in the future.
- The donated marrow is transfused to the patient, whose diseased cells have been destroyed by intensive chemotherapy. In time, the donated marrow engrafts and begins producing healthy blood cells.
Because patients are most likely to find a compatible donor within their own ethnic group, a diverse group of potential donors is needed. Over 2 million volunteers have joined the national registry, but only a small percentage are people of color.
Percentage of ethnic groups on the national registry:
- African American - 7.8%
- Asian/Pacific Islander - 5.7%
- Hispanic - 7.1%
- Native American - 1.6%
- Caucasian - 71.5%
When someone volunteers to join the national registry of potential donors, a blood sample is taken and is tissue-typed. Testing costs vary between regions. Because funding is limited, monetary donations are always welcome to help defray the cost of testing.
If you live in eastern Iowa and western Illinois region and would like to join the registry, call the University of Iowa Hospitals and Clinics at 800-944-8220.
If you live in another area of the United States, call the National Marrow Donor Program at 1-800-MARROW-2. |
