OBJECTIVES We sought to assess the validity of first-year intravascular ultrasound (IVUS) data as a surrogate marker for long-term outcome after heart transplantation. BACKGROUND Cardiac allograft vasculopathy (CAV) is a major impediment to long-term graft survival. Intravascular ultrasound is more sensitive than coronary angiography and detects intimal(More)
BACKGROUND A series of 13 islet autotransplantations and 13 islet allotransplantations performed between 1992 and 1999 at the University Hospital of Geneva are presented. Factors affecting the outcome are analyzed. METHODS Islet autotransplantation has been performed in seven patients with chronic pancreatitis and in six patients with benign tumors(More)
BACKGROUND Everolimus is a proliferation inhibitor designed to target chronic rejection, including prevention of acute rejection. Everolimus blocks growth factor-mediated transduction signals, preventing organ rejection by a mechanism different than that of calcineurin inhibitors and of mycophenolate mofetil (MMF). METHODS.: Everolimus (1.5 mg or 3 mg(More)
Two prospective, randomized studies evaluated everolimus 1.5 vs. 3 mg/day with steroids and low-exposure cyclosporine (CsA) (C2 monitoring) in de novo renal transplant patients. Everolimus dosing was adjusted to maintain a minimum trough level of 3 ng/mL. Study 1 (A2306; n=237) had no induction therapy; in Study 2 (A2307; n=256) basiliximab was administered(More)
BACKGROUND This 36-month, randomized, parallel-group study compared safety and efficacy of two doses of everolimus with mycophenolate mofetil (MMF) in de novo renal-transplant recipients. METHODS Renal-allograft recipients received 1.5 mg/day or 3 mg/day of everolimus or 2 g/day of MMF, plus full-dose cyclosporine (CsA) and corticosteroids after(More)
Everolimus 1.5 or 3 mg/day was compared with mycophenolate mofetil (MMF) 2 g/day in a randomized, multicenter 36-month trial in de novo renal allograft recipients (n = 588) receiving cyclosporine microemulsion (CsA) and corticosteroids. The study was double-blind until all patients had completed 12 months, then open-label. By 36 months, graft loss occurred(More)
The autoimmune disease type 1 diabetes in humans and NOD mice is determined by multiple genetic factors, among the strongest of which is the inheritance of diabetes-permissive MHC class II alleles associated with susceptibility to disease. Here we examined whether expression of MHC class II alleles associated with resistance to disease could be used to(More)
Xenogeneic islets could provide an unlimited source of tissue for the treatment of diabetes, and could in theory be transplanted repeatedly in a recipient. However, little is known on the consequences of islet re-transplantation in a recipient who has rejected a first graft. In this study, we investigated the functional consequence of xeno islet(More)
