Correlation between bioassayed plasma levels of FK 506 and lymphocyte growth from liver transplant biopsies with histological evidence of rejection.
FK 506, a novel immunosuppressive agent, was first used to reverse rejection in liver recipients who had failed to respond to conventional therapy.' The successful outcome of the initial study has led to clinical trials of FK 506 as the primary immunosuppressive agent for liver allografts and other organ transplants. 2-4 Ongoing studies include dosage protocols for optimal immunosuppression wit...
متن کاملBioassay of Plasma Specimens
L IVER transplantation has been increasingly used to treat end-stage liver diseases since the introduction of Cy A in combination with other immunosuppressive agents. 1 Although Cy A has a powerful immunosuppressive effect on allograft rejection, many transplant recipients still experience rejection episodes that are often irreversible. The nephrotoxicity of Cy A in some recipients has necessit...
متن کاملPlasma vs whole blood for therapeutic drug monitoring of patients receiving FK 506 for immunosuppression.
By retrospective analysis of 13,000 blood samples obtained from 248 patients receiving FK 506 therapy, we compared the suitability of plasma with that of whole blood as the matrix for therapeutic drug monitoring of FK 506. The plasma concentrations did not correlate with the concentrations in whole blood (r = 0.56). In contrast to plasma samples (analyzed by enzyme immunoassay), FK 506 was dete...
متن کاملIntra-CA1 administration of FK-506 (tacrolimus) in rat impairs learning and memory in an inhibitory avoidance paradigm
Objective(s): Calcineurin (CN) is a main phosphatase and a critical regulator of cellular pathways for learning, memory, and plasticity. The FK-506 (tacrolimus),a phosphatase inhibitor, is a fungal-derived agent and a common immune suppressant extensively used for tissue transplantation. To further clarify the role of CN in different stages oflearning and memory the main aim of this study was t...
متن کاملDistribution of FK 506 in plasma lipoproteins in transplant patients.
FK 506, a powerful. new immunosuppressive agent, is currently undergoing clinical trials in transplant patients. Like cyclosporine (CyA). FK 506 suppresses interleukin-2 production and receptor expression on T cells. 1.2 Additionally, both FK 506 and CyA are highly lipophilic. 3 CyA is mainly transported by lipoproteins in plasma.4 The objective of the present study is to characterize the distr...
