Randomized Controlled Trial Comparative Study Clinical Trial
Prophylaxis of heart transplant rejection with either antithymocyte globulin-, Minnesota antilymphocyte globulin-, or an OKT3-based protocol.
We compared an equine antithymocyte globulin (ATGAM)-based protocol with a Minnesota antilymphocyte globulin (MALG)-based protocol and a murine monoclonal CD-3 (OKT-)-based protocol in 3 groups of heart transplant (HT) recipients. Thirty-four recipients received a four-day course of ATGAM. Thirty HT recipients received a 14-day course of OKT3. ⋯ The ATGAM group received a higher dose of CyA during "induction" therapy than the OKT3 and MALG groups, and experienced a greater rise in post-transplant serum creatinine levels. We found no difference between the 3 groups in: preoperative creatinine levels, one-year post-transplant creatinine levels, number of patients who could be successfully "weaned" from steroids, or one-year survival. Other data are tabulated as episodes/patient: [table: see text] We conclude that ATG plus preoperative CyA is superior for rejection prophylaxis following heart transplantation when compared with either MALG plus postoperative CyA or OKT3 plus postoperative CyA.
