What is alloimmunity?
alloimmunity is the development of reactions to antigens produced by members of the same kind. The body recognizes them as foreign and attacks them, just as it was exposed to antigens from other organisms. This can cause disease or injury when the immune system tries to break foreign cells. This may be concerned in patients who receive transfusions, grafts and transplants, and it may also be a problem in some pregnancies. The immune system is recognized as friendly because they are produced by the body itself. In Aloimmunity, exposing another member of the same kind to these complexes leads to the formation of an immune reaction. It identifies the compounds as foreign and attacks them. This can be a significant problem with aloštěpy, transplantation materials taken from other people.
in pregnancy, sometimes to aloimune reaction between mother and fetus. The mother's body identifies the compound in fetal blood as an alien and its immune system attacks them. Aloimmunita mother can cause thrombocytopenia in the fetus or novoroZence. The severity of the condition may depend on the specific nature of reaction and treatment options may include monitoring and transfusion of fresh plates to increase the child's levels.
The development of aloimunity can play a role in transfusion reactions as well as in the rejection of graft or transplantation. Some types of transplants seem to be less prone to this problem than others. For example, the cornea can easily be transplanted by minimal comparison between the donor and the recipient. Other organs and tissues may require a very careful comparison to check apparent antigen reactions, and even then the patient's body may develop immunity to the antigen's transplantation material. Drugs to suppress the immune system can reduce the risk of aloimmune reactions.
Recipients are not the only ones who can develop aloimunity. Potential complications of bone marrow transplantation known as the "graft versus host" involves the development of reactionCE in the donor's work. It identifies the compounds found in the recipient's body as dangerous and begins to attack them. When the new bone marrow is replicated and begins to produce blood cells that enter circulation, they mount attacks on the recipient's own tissues. Patients may need to treat immune suppression to relieve the reaction, still allowing bone marrow to function.
