title: Neoquadruple induction with antithymocyte globulin/azathioprine/cyclosporine/prednisolone in simultaneous pancreas and kidney transplant recipients: 8.5-year results.
abstract: Ten years ago therapy with antithymocyte globulin or OKT3, azathioprine, cyclosporine, and prednisolone was the most common induction treatment for simultaneous pancreas/ kidney (SPK) recipients. Although immunosuppression was started after surgery, there was a high incidence of acute rejection episodes. In 1995, we modified the application of antithymocyte globulin and prednisolone by starting prior to reperfusion. Between 1995 and 1996, 30 patients underwent a first SPK. Prior to reperfusion, antithymocyte globulin (4-6 mg/kg body weight) and 250 mg prednisolone were administered. Intraoperatively, another 250 mg prednisolone were administered as well as intravenous azathroprine 3 mg/kg. After surgery up to 10 doses of antithymocyte globulin were administered and cyclosporine trough levels targeted to 200 to 250 ng/mL. Prednisolone was reduced gradually. After a median period of 8.5 years (range: 7.8-9.5 years) patient, pancreas, and kidney graft survival were 93.3%, 70%, and 76.7%, respectively. Sixteen acute rejection episodes were diagnosed in 11 patients (36.7%), who were treated with prednisolone bolus (n = 4), prednisolone with OKT3 (n = 8), prednisolone with antithymocyte globulin (n = 1), cyclosporine to tacrolimus conversion (n = 2), or plasmapheresis (n = 1). Two recipients died after SPK due to severe infection or carcinoma with functioning grafts. Seven further pancreas grafts were lost. Five kidney losses were observed besides the two recipients who died with functioning grafts. While previous protocols yielded a rejection incidence after SPK between 50% and 80%, we observed 60% of patients with no rejection episode during an 8.5-year median follow-up.
