Heart rejection

Carbon is inactive in blood and is not rejected from the human body. It is therefore increasingly used in artificial limbs, tendons and heart valves. 

Inhibition of immunomodulatory cytokines (Fig. 1) Anti-T-cell receptor antibodies Muromonab (OKT3, Orthoclone ) binds to the CD3 complex of the T-cell receptor and induces depletion of T-lymphocytes. It is applied to prevent acute rejection of kidney, liver, and heart allografts. Rapid side effects (within 30-60 min) include a cytokine release syndrome with fever, flu-like symptoms, and shock. Late side effects include an increased risk of viral and bacterial infections and an increased incidence of lymphproliferative diseases due to immunosuppression.

Vaccines Yes. Wyeth Vaccine, called VIG or vaccinia immune globulin, one dose by scarification. (Pre- and post-exposure vaccination recommended if greater than three years passed since last vaccine.) Persons who are pregnant, have clinical immunosuppression (such as persons who have undergone heart and other transplant operations and take medicines to control rejection of their new, transplanted organ), eczema, and/or leukemia/ lymphoma would be contraindicated for such vaccine. As one example, the fatality rate for immunosuppressed persons taking such vaccine could be as high as 75 percent or more.

The finding that the administration of 6-mercaptopurine to rabbits following exposure to bovine serum albumin prevented antibody formation [374] formed the basis for a new area of chemotherapy for purine analogues and other antimetabolites and was soon followed by the use of these drugs for the therapy of autoimmune disease and the suppression of homograft rejection. This subject has been reviewed in depth [ 12, 375, 375a], has occasioned a symposium [376], and has received much recent publicity as a result of human heart transplants. 

Cyclosporine A is a powerful immunosuppressive drug intended for preventing rejection of kidney, heart, and lung transplants. 

Allogeneic transplants For prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants. Gengraf and A/eora/have been used in combination with azathioprine and corticosteroids. Sanc//n n nne always is to be used with adrenal corticosteroids. Sandimmune a so may be used in the treatment of chronic rejection in patients previously treated with other immunosuppressive agents.

Apart from its potent antiproliferative activity, tetrasaccharide 15 was effective in blocking human complement in vitro and inhibited the release of heparan sulfate from cardiac microvascular endothelial cells. To overcome hyperacute rejection, the tetrasaccharide has been investigated in a guinea pig to rat cardiac xenotransplantation model and significantly prolonged the survival of heart recipients when compared to control and heparin treated groups [46].
