Will blood type change after bone marrow transplantation?

summary

Bone marrow transplantation is the only way to treat leukemia. So far, only this method can treat leukemia patients. Let's talk about whether the blood type of bone marrow transplantation will change.

Will blood type change after bone marrow transplantation?

First of all, a person's blood type is inborn and will not change for a lifetime. However, in certain circumstances, the individual's blood type can be changed. The first special case that can change the blood type is the transformation after transplantation of bone marrow stem cells. If a person suffers from blood diseases, such as leukemia, aplastic anemia, the body's hematopoietic function is weakened and destroyed, and the human hematopoietic function is completed by stem cells in the bone marrow.

Secondly, the patient's hematopoietic function is damaged, which indicates that there is a problem with his hematopoietic stem cells, so it is necessary to transplant other people's bone marrow hematopoietic stem cells. In this way, after transplantation of bone marrow stem cells, the patient's (recipient's) blood type may change, and the recipient's red blood cell type will change to the donor's red blood cell type after receiving bone marrow transplantation.

Finally, for example, if the donor is type A, no matter what kind of blood type the recipient is before transplantation, it will become type A. In 2000, researchers from the Institute of Hematology, Chinese Academy of Medical Sciences and the hospital of Hematology published that the blood type of 30 patients after stem cell transplantation had changed. There is a scientific basis for this. Therefore, when selecting blood donors, they will choose the correct blood type to avoid other diseases.

matters needing attention

Objective to understand the patients and their family members' understanding of the disease and the importance of bone marrow transplantation, and their understanding of the methods and process of bone marrow transplantation. Bone marrow transplant patients need to live in the sterile layer for nearly one month, isolated from the outside world, coupled with severe treatment reactions. To pay attention to the reaction after transplantation, do not take it lightly, to maintain a good mood, do not eat stimulating food.
