Randomized trial of tacrolimus plus mycophenolate mofetil or azathioprine versus cyclosporine oral solution (modified) plus mycophenolate mofetil after cadaveric kidney transplantation: results at 2 years.

BACKGROUND: A previous report described the 1-year results of a prospective, randomized trial designed to investigate the optimal combination of immunosuppressants in kidney transplantation. Recipients of first cadaveric kidney allografts were treated with tacrolimus+mycophenolate mofetil (MMF), cyclosporine oral solution (modified) (CsA)+MMF, or tacrolimus+azathioprine (AZA). Results at 1 year revealed that optimal efficacy and safety were achieved with a regimen containing tacrolimus+MMF. The present report describes results at 2 years. METHODS: Two hundred twenty-three recipients of first cadaveric kidney allografts were randomized to receive tacrolimus+MMF, CsA+MMF, or tacrolimus+AZA. All regimens contained corticosteroids, and antibody induction was used only in patients who experienced delayed graft function. Patients were followed up for 2 years. RESULTS: The results at 2 years corroborate and extend the findings of the previous report. Patients randomized to either treatment arm containing tacrolimus experienced improved kidney function. New-onset insulin dependence remained in four, three, and four patients in the tacrolimus+MMF, CsA+MMF, and tacrolimus+AZA treatment arms, respectively. Furthermore, patients with delayed graft function/acute tubular necrosis who were treated with tacrolimus+MMF experienced a 23% increase in allograft survival compared with patients receiving CsA+MMF (P=0.06). Patients randomized to tacrolimus+MMF received significantly lower doses of MMF compared with those administered CsA+MMF. CONCLUSIONS: All three immunosuppressive regi-mens provided excellent safety and efficacy. How-ever, the best results overall were achieved with tacrolimus+MMF. The combination may provide particular benefit to kidney allograft recipients who develop delayed graft function/acute tubular necrosis. Renal function at 2 years was better in the tacrolimus treatment groups compared with the CsA group.

Randomized trial of tacrolimus (Prograf) in combination with azathioprine or mycophenolate mofetil versus cyclosporine (Neoral) with mycophenolate mofetil after cadaveric kidney transplantation.

BACKGROUND: Our clinical trial was designed to investigate the optimal combination of immunosuppressants for renal transplantation. METHODS: A randomized three-arm, parallel group, open label, prospective study was performed at 15 North American centers to compare three immunosuppressive regimens: tacrolimus + azathioprine (AZA) versus cyclosporine (Neoral) + mycophenolate mofetil (MMF) versus tacrolimus + MMF. All patients were first cadaveric kidney transplants receiving the same maintenance corticosteroid regimen. Only patients with delayed graft function (32%) received antilymphocyte induction. A total of 223 patients were randomized, transplanted, and followed for 1 year. RESULTS: There were no significant differences in baseline demography between the three treatment groups. At 1 year the results are as follows: acute rejection 17% (95% confidence interval 9%, 26%) in tacrolimus + AZA; 20% (confidence interval 11%, 29%) in cyclosporine + MMF; and 15% (confidence interval 7%, 24%) in tacrolimus + MMF. The incidence of steroid resistant rejection requiring antilymphocyte therapy was 12% in the tacrolimus + AZA group, 11% in the cyclosporine + MMF group, and 4% in the tacrolimus + MMF group. There were no significant differences in overall patient or graft survival. Tacrolimus-treated patients had a lower incidence of hyperlipidemia through 6 months posttransplant. The incidence of posttransplant diabetes mellitus requiring insulin was 14% in the tacrolimus + AZA group, 7% in the cyclosporine + MMF and 7% in the tacrolimus + MMF groups. CONCLUSIONS: All regimens yielded similar acute rejection rates and graft survival, but the tacrolimus + MMF regimen was associated with the lowest rate of steroid resistant rejection requiring antilymphocyte therapy.

The utility of retroperitoneal kidney placement in simultaneous kidney pancreas transplantation.

Simultaneous kidney-pancreas (SPK) transplantation has become an accepted therapeutic modality for patients with Type I diabetes mellitus-mediated end-stage renal disease (ESRD). However, the intraperitoneal placement of the renal allograft may pose technical problems when attempting percutaneous biopsy or Doppler ultrasound examination. Recently, the Stanford University Transplant Center adopted the technique of retroperitoneal placement of the renal allograft with intraperitoneal placement of the pancreas allograft (RETRO). From August 1993 to August 1994, a total of 12 patients underwent SPK with this new technique. Twelve patients who had received SPK with the standard technique served as historical controls (INTRA). Demographic data, follow-up, operative time, creatinine and amylase on discharge, length of stay, intraoperative fluid requirements, rejection episodes, thrombotic complications, infections, and number of open and closed renal biopsies were compared between the two groups. Average length of follow-up was greater in the INTRA group (29.3 +/- 1.7 vs. 15.9 +/- 1.1 months). In addition, the RETRO group had significantly fewer open renal biopsies (1/15) in comparison to the INTRA group (7/12) (p < 0.001). The two groups otherwise did not differ in any of the parameters studied. We conclude that retroperitoneal kidney and intraperitoneal pancreas allograft placement is associated with a significantly decreased requirement for open renal biopsy with its associated operating room and anesthetic costs. In addition, the option of transcystoscopic or percutaneous needle biopsy of the pancreas allograft is preserved. This technique should be considered as an alternative to intraperitoneal placement of both the pancreas and renal allografts.

Extensive tissue necrosis associated with warfarin sodium therapy.

Skin and soft tissue necrosis is an uncommon but increasingly recognized complication of coumarin anticoagulant therapy. A patient is described with extensive involvement of all four extremities and the nose, requiring amputation of three extremities. The characteristic clinical features of the disorder are reviewed, with a discussion of the pathology, pathogenesis, and possible treatment modalities.
