What is a bone marrow transplant?
Bone marrow is a specialized fibrous tissue that is located inside the pelvic bones and in the cavities of the spongy bone, which is the primary or central lymphoid organ.
It performs the functions of the main hematopoietic and lymphopoietic organ, and with normal functional activity is responsible for maintaining a number of processes.
The bone marrow is responsible for the production of blood cells (red blood cells, platelets, and various types of white blood cells such as granulocytes, monocytes, lymphocytes, etc.).
As a result of exposure to various factors (major tumor or autoimmune diseases, as a result of aggressive treatment such as radiation therapy, chemotherapy), bone marrow damage and corresponding damage to its basic functions are observed in different ways.
Allogeneic transplantation: the bone marrow source is a healthy donor compatible with the antigens of the main tissue-compatible complex with the patient, and the donor's siblings are the most suitable, but the search for a match with unknown persons (in this case, the search for a suitable donor) becomes difficult and slows down. The main risks of allogeneic transplantation are associated with the occurrence of a transplant rejection reaction.
Syngeneic transplantation: the source is a healthy twin brother or sister, and this manipulation is extremely successful and effective, but rarely found in clinical practice (the chances of a patient having a twin or triplet in the general population are relatively low).
Pathological anatomy.
The main pathanatomic signs of Lyme arthritis are the consequences of immunopathological autoimmune reactions, manifested by the development of synovitis with characteristic morphological changes, which include hyperplasia of synovial cells, nonspecific villous hypertrophy, lymphoplasmocellular infiltration, follicle formation, and fibrin deposits. At the same time, as a result of intravascular persistence of borrelia in the vascular bed and synovial membrane, damage to the microcirculatory bed is observed by the type of obliterating endarteritis.
In the absence of treatment, synovial pannus forms in the perichondral region of the synovial membrane - vascular and fibrous tissue that grows into the cartilage and destroys it. Histopathological studies of the joints of infected experimental animals demonstrate significant destruction of their structures with significant synovial hyperplasia and hypertrophy, and the presence of neutrophil infiltrate is the cause of erosion of articular cartilage and superficial bone destruction. At the same time, there is an increase in collagen formation and the number of fibroblasts, which leads to fibrosis and ankylosis, and general joint deformity.
In addition, the experiment demonstrated the first evidence that Borrelia burgdorferi infection induces bone loss in mice, and this process occurs due to trabecular bone and does not depend on inhibition of osteoblast function, but is caused by impaired bone formation (decreased osteoblast survival and/or induction of osteoblast apoptosis).
