The family of 15-year-old Miguel Remberg, from Minas Gerais, is asking for help in donating bone marrow to a teenager, who was recently diagnosed with osteoporosis, a serious disease that can be treated with a transplant. The young man is from the town of Pouso Alegre in southern Minas, and discovered the disease after some complaints of pain.
According to the teen’s mother, in this case, the donor must be 100% compatible, otherwise the transplant cannot be performed. And no one in the family is compatible, so it was necessary for him to stand in line for this week’s transplant.
“In Miguel’s case, he is not producing blood cells in his bone marrow as he should, which is why he needs a transplant. We don’t have enough compatibility to donate our bone marrow, so we are looking for potential compatible donors,” the mother explained. (Check out the full video below )
Miguel is the eldest of three siblings. To call the family, Gabriela’s phone is (35) 99919-6219.
The chance is 1 in 100,000
Consisting of a liquid gelatinous tissue found inside the bones, the bone marrow produces blood components, including red blood cells or red cells, responsible for transporting oxygen in the circulatory system, or leukocytes or white cells, which are the most important factors of the defense system. Our bodies, the platelets that work in blood clotting.
Bone marrow transplant benefits patients with abnormal production of blood cells, which usually results from some types of blood cancer such as leukemia and lymphoma, as well as patients with myelomegaly, among other diseases.
According to Hemominas, the chance of finding a compatible donor between siblings, children of the same father and mother, is estimated to be about 25% to 30%. Among unrelated people, this probability can be as high as 1 in 100,000 registered candidates.
“Compatibility is verified by the similarity between the donor’s leukocyte antigens and those of the recipient, by testing for HLA (human leukocyte antigens). Therefore, the more candidates registered, the higher the chances of finding the perfect donor for patients who need a transplant.”
If a candidate is deemed compatible with a patient, he or she will be consulted again to make a decision on donation. With the donor confirmed, further blood tests will be done to ensure compatibility. The candidate then undergoes rigorous checks to assess his health, and if all goes well, he will become a donor,” he adds.
How do I register for a donation?
Candidates for bone marrow donors are registered by Fundação Hemominas. To join the donor registry, you must:
Be between 18 and 35 years old, in good health and not suffering from diseases such as infectious diseases or blood diseases;
Bring an official identification document with a photo.
– Collect a 5ml blood sample for testing, for the HLA (Human Leukocyte Antigen) test, which will determine the genetic characteristics needed for donor-patient compatibility. The type of HLA will be recorded in the National Registry of Bone Marrow Donors (Redome), which is associated with the National Cancer Institute (Inca).

“There is no schedule – candidates to donate must inform themselves directly about the unit fundraising segment and they will be present at the times designated by each. Likewise, online scheduling is not available for this type of service,” Hemominas explains.
How is it combined?
There are two main ways to collect bone marrow from a donor. The choice of the type of group is not a decision of the donor or the patient, but a medical indication, according to the type of pathology or diagnosis of the patient. So, look at two opportunities:
Punctures in the pelvic bone with special needles under anaesthesia. Donors undergo a small surgery that takes about 90 minutes.
Apheresis, a peripheral collection procedure similar to donating blood. It does not require hospitalization or anesthesia.
Also, according to Hemominas, the patient is treated with chemotherapy, which destroys his marrow, and receives donated bone marrow via a blood transfusion. Within two weeks, the transplanted bone marrow will produce new cells.
For donors, the risks are almost non-existent. Only 10% of the bone marrow is removed, and within a few weeks, the donated marrow will be regenerated by the body. A bone marrow transplant is the only hope for a cure for many people with leukemia and other blood disorders.
