Severe cardiac allograft rejection remains a serious problem despite the
advances of cyclosporine-based immunosuppression. This study analyzes our
experience with 202 recipients of cardiac allografts who were treated
primarily with cyclosporine and prednisone. Failure of such therapy in 86
patients (43%) resulted in 105 episodes of advanced cardiac allograft
rejection as diagnosed by endomyocardial biopsy. Of 101 rejection episodes
that were initially treated with intravenous pulse therapy, 48 (48%) were
successfully resolved, yet 60% of these successes were associated with
major infections. Patients in whom steroid therapy failed or was
contra-indicated received intravenous antithymocyte globulin (ATG) or
intravenous monoclonal antibody (OKT3). ATG and OKT3 successfully reversed
severe rejection in 26 (81%) of 32 and in 13 (93%) of 14 episodes,
respectively. Infectious complication rates were 54% and 21%, respectively.
Because the majority (87%) of these rejection episodes occurred within the
first 30 days after treatment, many of them may have resulted from
inadequate immunosuppressive induction therapy. Based on our results, we
believe that advanced cardiac allograft rejection may be managed best by
individualizing immunosuppressive therapy, thus enhancing prevention, and
by adding OKT3 to the regimen when rejection occurs.
