ABSTRACT
【Objective】To investigate the role of mycophenolate mofetil (MMF) in the prevention of acute rejection in renal transplantation.【Methods】A total of 106 patients were randomized into two groups.One group received MMF (n=56),the other received azathioprine (Aza) (n=50).The time of the following study was within the first 6 months after transplantation.【Results】The rate of acute rejection of group receiving MMF was 20%,it′s lower than that of the group receiving Aza 44% (P<0.01).The recovery rate of acute rejection treated by methylprednisolone (MP),in MMF group 82% was higher than Aza group 55%.(P<0.05).Meanwhile the hepatotoxicity as well as cytomegalovirus (CMV) infection were lower in MMF group than those in Aza group.【Conclusion】MMF as a new anti-rejection drug could more effectively prevent acute rejection than Aza after renal transplantation,and has lower toxicity and side effect.
ABSTRACT
Objective To examine the levels of CD38+CD8+ T lymphocyte in kidney transplant recipients with cytomegalovirus infection and investigate the possibility in monitoring the cytomegalovirus active infection after kidney transplantation. Methods Before and after kidney transplantation, CD38+ CD8+T lymphocyte and cytomegalovirus leucocyte antigen were measured respectively by flow cytometry and immunohistochemistry method in 56 transplant recipients. The data of CD38+CD8+ T lymphocyte and the cylomegalovirus leucocyte antigen were analyzed. Results Before kidney transplantation, cytomegalovirus leucocyte antigen was negative among all the patients, while the mean ratio of (CD38+CD8+)/CD8+ was 0. 11?0. 05. In 14 recipients whose cytomegalovirus leucocyte antigen was positive, the appearing time of the positive antigen was(32. 7?16. 6) days of post-transplantation, meanwhile, the mean ratio of (CD38+ CD8+)/CD8+ was 0. 43?0. 21 (29. 6?8. 4) days of post-transplantation, which was significantly higher than that of pre-transplantation. After the treatment with ganciclovir intravenously, the cytomegalovirus leucocyte antigen became negative and the mean ratio of (CD38+CD8+)/CD8+ decreased to 0. 16?0.09 which was significantly lower than that of pre-treatmmt ( P
ABSTRACT
Objective To study the effect of delayed cyclosporine(CsA) therapy combined with prophylactic use of antilympho-cyte globulin (ALG) (sequential quadruple immunosuppressive protocol) on early graft function in renal transplantation. Methods The experimental group included 90 renal recipients who were treated with posttransplant quadruple sequential therapy. Their short-term outcomes were compared with those of 215 recipients who were given CsA immediately after transplantation(control group). Results Not only was the recovery of renal allograft function faster in the experimental group ( P 0. 05). Conclusion Delayed CsA therapy in conjunction with prophylactic use of ALG is a desirable protocol for treating posltransplant renal recipients.
