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) and pharmacodynamics (PD) and 6-month b...

The development of immunosuppressive drugs has in recent years been focused on prevention of acute rejection. This has led to an increase in one-year allograft survival. However, these drugs have non-immune effects which contribute to the high incidence of late graft loss, as a consequence of chronic allograft nephropathy, and the death of patients. As an immune-specific alternative to conventi...

Ischemia reperfusion injury occurs in the kidney when blood supply is interrupted in clinical settings such as kidney transplantation or nephron sparing surgery for renal tumors. These lesions lead to acute kidney injury (AKI) a detrimental situation associated with impaired short-term allograft function (delayed graft function or primary non function) but also long-term transplant survival thr...

Chronic allograft nephropathy (CAN) represents progressive deterioration of renal allograft function with fibroinflammatory changes. CAN, recently reclassified as interstitial fibrosis (IF) and tubular atrophy (TA) with no known specific etiology, is a major cause of late renal allograft loss and remains a significant deleterious factor of successful renal transplantation. Carbon monoxide (CO),...

Chronic allograft nephropathy (CAN) is a major indication for initiation of sirolimus (SRL) in renal transplantation (TX) to prevent deterioration of renal function. We evaluated whether the CAN score at time of sirolimus rescue (SRL-R) predicts renal allograft function. CAN score is the sum of the following 4 categories: glomerulopathy (cg, 0-3), interstitial fibrosis (ci, 0-3), tubular atroph...

Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that have been increasingly linked to both normal physiology and abnormal pathology in the kidney. Collectively able to degrade all components of the extracellular matrix, MMPs were originally thought to antagonize the development of fibrotic diseases solely through digestion of excessive matrix. However, increasing ...

Almost all kidney transplant recipients with diabetes mellitus will eventually develop recurrence of diabetic nephropathy in their allograft. Despite this high incidence, there are very few reported cases of diabetic nephropathy of diffuse type, and the nodular sclerosis form is uncommon. Recurrence of diabetic nephropathy of nodular glomerulosclerosis type usually occurs during the second deca...
