Arteriosclerotic intimal proliferation is one of the main long-term complications of organ transplantation. Low-molecular-weight, heparin-like molecules prevent myointimal proliferation in arterial wall injury and limit rejection in skin allografts. Cyclosporin limits rejection but has no major effect on intimal proliferation. Therefore, an experimental protocol was designed to test whether hep...

Eighteen patients were treated with primary cadaveric renal transplantation using cyclosporin A therapy, and four more patients undersent cadaveric retransplantation. Eleven of the 22 recipients were conditioned with lymphoid depletion before transplantation, using thoracic duct drainage or lymphapheresis for two to eight and one-half weeks. Cyclosporin A was begun a few hours before grafting. ...

Cyclosporin was isolated in 1970, by Jean François Borel at Sandoz Laboratories (Basel, Switzerland), from the soil fungus Tolypocladium inflatum (Borel et al., 1995; Amor et al., 2010). The compound was initially identified as a possible antifungal agent, but it was subsequently shown to have limited antifungal activity. However, in 1976, the drug demonstrated potent immunosuppressive properti...

Oral cyclosporin A was used as prophylaxis against graft-versus-host disease in (a) 31 patients with acute leukaemia or aplastic anaemia given transplants of HLA-matched bone marrow and (b) five patients with inborn errors of metabolism given transplants of haplotype-identical (parental) bone marrow. Twenty-six patients survived longer than two months after the operation. Despite the cyclospori...

Cyclosporin A (CsA) shows cytoprotective properties in many cellular and in vivo models that may depend on interference of the interaction of cyclophilin A with calcineurin or of cyclophilin D with the mitochondrial permeability transition (PT) pore. The nonimmunosuppressive cyclosporin derivative N-methyl-4-valine-cyclosporin (PKF220-384) inhibits the mitochondrial permeability transition (MPT...

OBJECTIVE To compare tacrolimus with cyclosporin for immunosuppression in renal transplantation. DESIGN Meta-analysis of randomised trials of two treatments after kidney transplantation. IDENTIFICATION Four studies involving 1037 patients. Trials were included if they were randomised, the intervention group received tacrolimus, the control group received cyclosporin, the patients were follo...

Grepafloxacin and levofloxacin transport by Caco-2 cell monolayers was examined to characterize the intestinal behavior of these quinolones. The levels of transcellular transport of [(14)C]grepafloxacin and [(14)C]levofloxacin from the basolateral to the apical side were greater than those in the opposite direction. The unidirectional transport was inhibited by the presence of excess unlabeled ...

Nephrotic syndrome in minimal change lipoid nephrosis and focal segmental glomerulosclerosis may be due to alteration of glomerular anionic sites by a lymphokine. Six adults with nephrotic syndrome who were resistant to treatment with corticosteroids and immunosuppressants were treated with cyclosporin A. In three patients with minimal change lipoid nephrosis who had been nephrotic for 3.5 to 2...

BACKGROUND Most liver transplant recipients receive either cyclosporin or tacrolimus to prevent rejection. Both drugs inhibit calcineurin phosphatase which is thought to be the mechanism of their anti-rejection effect and principle toxicities. The drugs have different pharmacokinetic profiles and potencies. Several randomised clinical trials have compared cyclosporin and tacrolimus in liver tra...
