The donation of marrow, essential in blood cancers was prohibited since 1983 to homosexuals and bisexuals. This decision, which follows the authorization to donate blood since 2016, allows new, generous donors to register on potential donor registries.
According to the figures of France ADOT, the federation of ATassociations for the Dwe haveOrganes and Tfrom human sources, in 2015, 18,848 people registered on the French file. As of December 31, it contained 248,000 people, of whom only 34% were men. Worldwide, there were approximately 26 million donors in 79 international files. Registering on the bone marrow donor registry also means registering for a chain of generosity ...
One of the last chances of healing in blood cancer is a bone marrow transplant to replace that of the patient who is unable to produce healthy cells. Because all blood cells, red blood cells transporting oxygen but also white blood cells responsible for our immune defenses and the artisan wafers of the fight against bleeding are produced by the bone marrow.
One of the big problems with this donation is that many people confuse it with the spinal cord which is what drives all our nerves to the brain, and what is called bone marrow. When you see a severed bone, the marrow is the middle part a little soft. She has a vital role in our survival. It is she who makes all the cells of the blood; I remind you of their name red blood cells, white blood cells and platelets ...
Red blood cells are used to carry oxygen from the lungs to the rest of the body. White blood cells fight infections. They are the ones who produce the antibodies that defend us. To be complete, one must also add the platelets that are responsible for coagulation.
Whenever these elements are missing there is a big problem. More red blood cells is anemia. Bad white blood cells, we are there in diseases like leukemias; not enough platelets ... bleeding. It's a bit caricatural but it is a very complicated in detail.
Against anemia we have blood transfusions which are very useful. But sometimes, in leukaemias, the whole factory, the marrow is deficient. This is where the transplant comes in.
The removal of marrow
he is under general anesthesia. It requires hospitalization of the donor for a period of two days. The procedure itself lasts one to two hours. It involves taking punctures in the bones of the pelvis a quantity of bone marrow calculated according to the weight of the donor. So it's not a gift as simple as blood, but it's every time to save a life. And then the probability of those who are registered on the register to give is not very high. The marrow of the donor is reconstituted quickly and without problems. This is why we could theoretically give several times, but there were a little less than 198 samples in France last year for 248,000 potential donors registered; the probability of giving once is extremely rare.
Almost everyone can give. You must be less than 50 years old when you register (the gift, being possible until you turn 60),
You have to be compatible, because even if you inject what looks like a liquid, it's still a transplant. In fact that one receives blood or a heart, it is always the same problem of compatibility which intervenes
In the case of the marrow, to find a donor, we will first turn to the brothers and sisters of the patient. Indeed, there is a chance in 4 for two siblings to have the same compatibility code: If this is not the case, then the doctor will look in a global donor file that lists 13 million volunteers with their information.
You must be in good health register on a volunteer file. One gives then very simply his blood, only once, to determine the characteristics of each one.
Between the inscription on the file and the actual donation, a very variable period of time can pass (from a few months to many years). It is also possible that the gift never occurs if no patient is ever compatible.
It's anonymous and free! They are 248 000 in France ready to give! still a little effort because it is the variety of donors that is the strength of this file.
