Abstract/OtherAbstract:
The aim of the present investigation was to study the possible synergistic effect between cyclosporin A (CsA) and antithymocyte globulin (ATG), using the potent immunostimulator, Linomide. DA rats were transplanted with a PVG/c heart to the neck vessels, and the recipients were treated for 10 days with oral CsA (10mg/kg), oral Linomide (160mg/kg) and/or ATG, which was given as a single dose of either 0.02 ml, 0.1 ml or 0.2 ml prior to transplantation. Rats given a combination of ATG and Linomide or CsA and Linomide were used as controls. Synergism between CsA and ATG was tested using the two immunosuppressive drugs given in combination in order to override the challenge of Linomide. CsA or ATG treatment alone resulted in rats with long-term surviving grafts. Addition of Linomide to CsA-treated recipients was followed by early graft rejection. Similarily, Linomide triggered rejection in rats given a low dose of ATG and in recipients given a high dose of ATG if Linomide treatment was prolonged to 21 days. The combination of ATG, CsA and 21 days of Linomide resulted in a significantly prolonged graft survival compared with either ATG + Linomide or CsA + Linomide. These findings demonstrate the synergistic capacity of ATG and CsA in combined immunosuppressive therapy.
