In medicine, photopheresis (aka extracorporeal photopheresis or ECP) [1] is a form of apheresis and photodynamic therapy in which blood is subject to apheresis to separate buffy coat (WBC + platelets) from whole blood, chemically treated with 8-methoxypsoralen (instilled into a collection bag or given per os in advance), exposed to ultraviolet light (UVA), and then returned to the patient.

Photopheresis – used to treat graft-versus-host disease, cutaneous T-cell lymphoma, and rejection in heart transplantation. Immunoadsorbtion with Staphylococcal protein A -agarose column – removal of allo- and autoantibodies (in autoimmune diseases, transplant rejection, hemophilia) by directing plasma through protein A-agarose columns.
Chronic rejection is an insidious form of rejection that leads to graft destruction over the course of months, but most often years after tissue transplantation. [12] The mechanism for chronic rejection is yet to be fully understood, but it is known that prior acute rejection episodes are the main clinical predictor for the development of ...
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors , which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia due to bone marrow insufficiency.
Chronic graft-versus-host disease also attacks the above organs, but over its long-term course can also cause damage to the connective tissue and exocrine glands. [7] Mucosal damage to the vagina can result in severe pain and scarring, and appears in both acute and chronic GvHD.
The Immunologic Constant of Rejection (ICR), is a notion introduced by biologists to group a shared set of genes expressed in tissue destructive-pathogenic conditions like cancer and infection, along a diverse set of physiological circumstances of tissue damage or organ failure, including autoimmune disease or allograft rejection. [1]
Ciclosporin is used in the treatment of acute rejection reactions, but has been increasingly substituted with newer, and less nephrotoxic, [7] immunosuppressants. Calcineurin inhibitors and azathioprine have been linked with post-transplant malignancies and skin cancers in organ transplant recipients.
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system.Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies.
