Tacrolimus is a product of fermentation of Streptomyces, and belongs to the family of calcineurin inhibitors. It is a widely used immunosuppressive drug for preventing solid-organ transplant rejection. Compared to cyclosporine, tacrolimus has greater immunosuppressive potency and a lower incidence of side effects. It has been accepted as first-line treatment after liver and kidney transplantati...

More effective immunosuppressive treatment in children following organ transplantation has significantly improved the survival of the grafts. Therefore, quality of life, long-term prognosis and adverse drug reactions have become more important. One of the main complications of immunosuppressive drugs is infections of the respiratory tract, but irreversible damage to the airways has not been des...

The clinical laboratory plays a major role in support of transplantation. Depending on the spectrum and number of transplants performed, such programs can consume up to 35% of all laboratory testing. This testing can be transplantation-nonspecific or -specific. The former constitutes routine laboratory procedures in various areas of laboratory medicine that are common to other categories of pat...

Cyclosporin A (ciclosporin), a potent and clinically important immunosuppressive drug (Sandimmun), represents the main component of a group of over 25 closely related, cyclic undecapeptides produced by the fungus Tolypocladium inflatum. By feeding experiments using DL-alpha-allylglycine as precursor, specific incorporation in position 2 was attained leading to [Allylgly2]cyclosporin A. Exogenou...

Mitogen-induced transformation and the production of reactive oxidants by mononuclear leucocytes (MNLs) from patients with chronic dermatological disorders were investigated in vitro before and during the administration of the antimycobacterial/immunosuppressive agent clofazimine (200 mg 3 times weekly). Seven patients, 4 with lichen planus and 3 with cutaneous lupus erythematosus, were include...

Serial rosette inhibition tests were performed on nine patients with Crohn's disease undergoing immunosuppressive therapy in an attempt to estimate the minimum amount of drug necessary to maintain immunosuppression. The rosette inhibition titre was found to be higher in immunosuppressed patients than in normal subjects. However, there was no consistent correlation of the rosette inhibition titr...

Aplastic anemia is a relatively uncommon disease and conventional management options include immunosuppressive drugs and/or haematopoeitic stem cell transplantation. It is now known that the pathogenesis of aplastic anemia is immune mediated. Mycophenolate mofetil is a common immunosuppressive drug now used mainly in prophylaxis of graft rejection in organ transplant and also for prevention/tre...

2-Amino-2-[2-(4-octylphenyl)]-1,3-propanediol hydrochloride (FTY720) is a potent immunosuppressant which has been approved by the Food and Drug Administration (FDA) as a new treatment for multiple sclerosis. As an immunosuppressant, it displays its anti-multiple sclerosis, immunosuppressive effects by activating sphingosine-1-phosphate receptors (S1PRs). In addition to the immunosuppressive eff...
