INTRODUCTION Efficacious prophylaxis of acute rejection episodes (ARE) requires adequate exposure to each component of the immunosuppressive treatment from the first days after renal transplantation. The aim of the present study was to evaluate the correlation between cyclosporine (CsA) and mycophenolic acid (MPA) exposure based upon pharmacokinetics (PK)(More)
BACKGROUND In liver transplantation, mycophenolate mofetil (MMF) is habitually administered using fixed doses. We assessed whether mycophenolic acid (MPA) monitoring could be advisable in liver transplant patients. METHODS In 15 liver transplant patients receiving tacrolimus, daclizumab and MMF (1 g bid, orally), we determined the 12-hour plasma MPA(More)
Between 1989 and 2002, 178 renal transplants were performed in 168 pediatric patients in Chile. The mean age was 10.9 +/- 3.7 years (range 1 to 17.9). End-state renal disease etiologies were: congenital renal hypoplasia/dysplasia, chronic glomerulonephritis, and reflux nephropathy. Seventy received a graft from a living donor (LD), and 108 from a cadaveric(More)
BACKGROUND Graft survival depends on adequate immunosuppression. To evaluate the effect on the immune system of immunosuppressive therapies using calcineurin inhibitors (CNIs), several pharmacodynamic indices have been proposed to complement pharmacokinetic data. In this preliminary study we compared some of these parameters during combined(More)
We evaluated the in vitro capacity of FK778, alone or in combination with other immunosuppressive drugs: Tacrolimus (TRL); Sirolimus (SRL), Everolimus (EVL), to inhibit clonal expansion of T-lymphocytes and expression of lymphocyte-activation surface antigens; secondly, we compared the immunosuppressive potential of FK778 combined with TRL, SRL and EVL with(More)
We investigated the relationship between the pharmacokinetics and pharmacodynamics of cyclosporine in 15 stable renal transplant patients in order to define an effective and safe therapeutic range. The area under the curve of the first 4 h (AUC(0-4)), trough (C(0)) and 2 h (C(2)) levels showed median values of 1655 ng x h/ml, 114 ng/ml and 384 ng/ml,(More)
BACKGROUND There is a correlation between cyclosporine (CsA) pharmacokinetics (PK) and pharmacodynamics (PD), especially 2 hours after drug administration. AIM To evaluate the relationship between CsA PK and PD profiles in two groups of stable renal transplant patients treated with CsA alone or CsA plus mycophenolate mofetil (CsA+MMF), so as to define the(More)
A new method of obtaining electrographic recordings from endoscopically-based intraventricular monitoring was performed in three patients with intractable epilepsy, who subsequently underwent open resective neurosurgery. As a minimally invasive procedure, it was associated with no peri-operative complications, and electrical intraoperative monitoring of the(More)
