Bone Marrow Transplant
- The bone marrow is a fatty, spongy tissue that is responsible for the development of red blood cells, white blood cells, and platelets.
- The three are important components of the blood and are essential for basic life functions.
- Damage to the bone marrow can be a result of infection, disease, or chemotherapy. The damage can prove to be life-threatening as the development of blood cells and platelets is compromised.
- Damaged or destroyed bone marrows have to be replaced in a procedure known as a bone marrow transplant.
- This involves transplanting blood stem cells that go to the bone marrow, producing new blood cells, and helping out in the development of new bone marrow.
- It is a process of replacing damaged stem cells with healthy ones that come from a donor that matches with the patient requiring the bone marrow transplant.
- The cells can also come from the patient’s body.
- They may be taken before a medical procedure such as chemotherapy and harvested to be used later if required.
Let’s look at bone marrow transplant in detail:
Who Needs a Bone Marrow Transplant?
A bone marrow transplant is required when a person’s bone marrow is not healthy enough to perform its functions. This may be due to conditions such as:
- Cancers affecting the marrow such as lymphoma, leukemia, and multiple myeloma.
- Aplastic anemia, which affects the marrow and causes it to stop making blood cells.
- Thalassemia, a genetic disorder that causes the body to make abnormal hemoglobin.
- Damage to the bone marrow from chemotherapy.
- Sickle cell anemia, an inherited blood disorder that causes the development of abnormal red blood cells.
- Congenital neutropenia, an inherited condition that results in recurring infections.
Risks
Risks commonly associated with a bone marrow transplant are:
- Nausea
- Pain
- Chills
- Fever
- A drop in blood pressure
- Shortness of breath
- Headache
These conditions are usually short-lived, but your risk of getting them depends on:
- Age
- Type of marrow transplant
- Overall health
- The disease you are receiving treatment for
Some serious, but rare, complications include:
- Cataracts
- Organ damage
- Graft-versus-host-disease (GVHD)
- Anemia
- Infections
- Mucositis
- Bleeding in the brain, lungs, and other parts of the body
- Graft failure
- Early menopause
- Nausea, diarrhea, and vomiting
Preparation
- A bone marrow transplant is preceded by significant preparation.
- You will need to undergo tests to see what type of transplant you need, with autologous being done with your stem cells and allogeneic using cells from a donor.
- You have to ask a lot of questions from your doctor and make sure you are aware of all the risks before going ahead with it.
After the Procedure
- The success of the procedure is highly dependent on how closely the patient and donor’s cells match.
- The first sign of success is rising white blood cell count, which may take 28 days to appear.
- Overall recovery can take up to 3 months during which a patient will be constantly monitored to make sure they do not reject the donor’s cells.
