The kidney transplant program at the Bergamo Center.
    Clinical transplants, 2000

    The kidney transplant program at the Ospedali Riuniti of Bergamo, Italy was established in 1989. Since its inception, 367 patients have been transplanted, including 357 kidney transplants from cadaveric donors and 10 from living-related donors. Overall 8-year patient and graft survival rates were 94% and 77%, respectively. By 1995 our unit co-ordinated the activity of the Department of Immunology and Clinics of Organ Transplantation, Ospedali Riuniti--Mario Negri Institute for Pharmacological Research, Bergamo. The dual "marginal" kidney transplant program in the same recipient was launched in August 1997, as a part of an international cooperative network which established the "Double Kidney Transplant Group" (DKG). To date, 19 dual kidney transplants have been successfully performed in our center. Four combined heart-kidney transplants and 2 combined liver-kidney transplants have also been performed. During the past 4 years several studies involving conventional antirejection drugs were carried out, particularly focussing our attention on cyclosporine (CsA) through pharmacokinetic and pharmacodynamic approaches: 1) a simplified method to evaluate daily exposure to CsA has been set up; 2) the monitoring of calcineurin activity in whole blood samples was evaluated as a way to optimize CsA dosing. As for the new immunosuppressants, studies are ongoing with mycophenolate mofetil (MMF). We are co-ordinating a prospective multicenter randomized trial of steroid sparing in kidney transplant recipients given MMF or azathioprine as a part of their immunosuppression therapy (MY.S.S. study). This involves 9 Italian transplant centers and 2 European centers. Up to now 325 patients have been randomized. Moreover we have set up an HPLC method for measuring plasma mycophenolic acid (MPA), and examined the possibility of optimizing MMF dosing by drug pharmacokinetic monitoring. Further studies have been addressed to chronic allograft nephropathy. The nature and mediators of renal lesions in kidney transplant patients given CsA have been explored taking into account the gene expression of endothelin-1, RANTES and MCP-1 in graft specimens from patients who had evidence of CsA nephrotoxicity, chronic rejection, or no lesions at histological examination. The impact of percutaneous transluminal angioplasty and stenting of posttransplant renal artery stenosis on renal function recovery was also recently examined. From this study we conclude that the procedure is safe and effe

Renal manifestations in toddlers with Takayasu's arteritis and malignant hypertension.
    Pediatric nephrology (Berlin, Germany), 2009, Volume: 24, Issue:6

    Three children under the age of 3 years presented with malignant hypertension, proteinuria, and acute kidney injury. Takayasu's arteritis was diagnosed on the basis of clinical symptoms of weight loss and low grade fever in conjunction with elevated sedimentation rate and radiographic evidence of aortic and renal artery stenosis. One patient had a renal biopsy which showed arteriolar sclerosis and focal glomerulosclerosis. All three patients required multiple antihypertensive agents, ultimately including angiotensin receptor blockers and/or angiotensin converting enzyme inhibitors. The vasculitis was treated with pulse corticosteroids followed by cyclophosphamide in one patient and mycophenolate mofetil as maintenance therapy in all. Follow-up has ranged from 2 to 8 years. Although global renal function has normalized in each patient, two have unilateral non-function of one kidney. The last patient has persistent aortic and renal artery stenosis with complex collateralization requiring ongoing medical and anticipated surgical management.
