Donating Bone Marrow Is Like shooting fish in a barrel and Important: Here'southward Why

Os marrow is a soft, spongy material institute in your big bones. Information technology makes more than 200 billion new blood cells every day, including red blood cells, white blood cells, and platelets. Merely for people with bone marrow affliction, including several types of cancer, the procedure doesn't work properly. Often, a bone marrow transplant is a person's best chance of survival and a possible cure. The good news is that altruistic bone marrow can be every bit like shooting fish in a barrel and painless as giving claret. share on twitter

What you lot need to know about bone marrow transplants

A os marrow transplant replaces diseased bone marrow with healthy tissue, ordinarily stalk cells found in the blood. That's why bone marrow transplants are also called stalk cell transplants. In an allogeneic transplantation (ALLO transplant), blood stem cells from the os marrow are transplanted from a donor into the patient. The donor stalk cells can come from either the blood that circulates throughout another person's body or from umbilical cord blood.

But there's a catch. Before a person receives an ALLO transplant, a matching donor must be plant using human leukocyte antigen (HLA) typing. This special claret test analyzes HLAs, which are specific proteins on the surface of white blood cells and other cells that make each person's tissue type unique. HLA-matched bone marrow is less likely to cause a possible side event of transplantation called graft vs. host disease (GVHD). GVHD is when allowed cells in the transplanted tissue recognize the recipient's body as "foreign" and attack information technology.

Simply about 30% of people who need a transplant can find an HLA-matched donor in their immediate family. For the remaining 70% of people, doctors need to find HLA-matched os marrow from other donors. In 2016, that equals nearly xiv,000 people — from very young children up to older adults — in the Usa who need to find a donor outside of their shut family.

How a match is made

The National Marrow Donor Program (NMDP) has a registry of potential donors that might be the lucifer a patient needs. Here'south how the donation process works:

  1. Yous register with the NMDP online or in person at a donor center. You can find a heart by calling the price-gratis number 1-800-MARROW2.

  2. You collect cells from your cheek with a cotton swab or provide a pocket-size blood sample. This is washed by following directions in a mail-in kit or at a donor center. The sample is analyzed to determine your HLA blazon, which is recorded in the NMDP national database.

  3. If an HLA friction match is fabricated with a patient in need, the NMDP contacts yous. A donor eye takes a new sample of your claret, which is sent to the patient'due south transplant center to confirm the HLA lucifer. Once doctors ostend the friction match, you'd meet with a counselor from the NMDP to talk almost the procedures, benefits, and risks of the donation process. You then decide whether you lot're comfortable with donating.

The bone marrow donation process

If you hold to donate bone marrow, you'll likely practice what'south called a peripheral claret stalk cell (PBSC) collection. Here's how it works:

  • For 5 days leading up to the donation, you'll get a daily 5-minute injection of granulocyte colony-stimulating factor (One thousand-CSF), a white blood prison cell growth hormone.

  • On solar day 5, a trained health care provider will place a needle in each of your arms. One needle will remove blood, and a auto circulates the claret and collects the stalk cells. Your blood then is returned to your body through the second needle. The process takes about 3 hours and may be repeated on a second donation solar day. Side furnishings include headaches, bone soreness, and discomfort from the needles during the process.

Although less common, some donors may be asked to undergo a bone marrow harvest, during which doctors take bone marrow from the dorsum of a donor's hip os during surgery. Donors commonly go dwelling house the same day of the surgery and can return to normal activity inside i week. Common side effects include nausea, headache, and fatigue, nearly often related to the anesthesia. Bruising or discomfort in the lower back is likewise mutual.

The end result? You could assistance cure someone's illness.
