Filter by:Varicella zoster virus is part of the herpesvirus group and causes chickenpox in exposed individuals. The majority of the population is seropositive for this virus. Reactivation of varicella zoster virus occurs in up to 30% of the general population over 60 years old. Solid organ transplant recipients receive lifelong immunosuppression drugs and are at great risk of reactivation of all herpesviruses including the varicella zoster virus regardless of age. The vaccine has been shown to be effective in preventing shingles in the general population. The investigators' purpose is to determine how well the vaccine works in patients on renal replacement therapy and post-transplant.
This is a multicentre study examining the use of Advagraf-minimization strategy and/or the use of an inhibitor of the renin-angiotensin system in reducing chronic rejection in renal allografts.
Kidney transplantation in the elderly is a challenge since patient's co-morbidity and the decreased injury threshold of older grafts may limit the benefits of transplantation in these patients. To compare favourable effects between low dose tacrolimus (LD-Tac) and mycophenolate-mofetil (MMF) in this patient population the investigators conducted a one year prospective multicenter randomized controlled trial. 90 kidney transplant recipients > 65 years with cadaveric grafts (> 65 years) from 5 centers were enrolled and received baseline immunosuppression with daclizumab induction (1 mg/kg) at day one and day 14, LD-Tac (trough level 5-8 µg/ml), MMF (1-2 g/d) and steroids. After three months, patients were centrally randomized either to MMF (1-2 g/d) and steroids (23 patients) or to LD-Tac and steroids. Follow-up visits were performed every 4 weeks up to one year. Protocol biopsies were performed after one year. The investigators' primary hypothesis is that the biopsy proven rejection rate in the MMF group is not significantly different compared to the LD-Tac group after one year. The investigators' secondary hypothesis is that graft function in the MMF group (reflected by the glomerular filtration rate and protocol biopsy result) is superior to the graft function in the LD-Tac group.
This study is designed to optimize calcineurin immunosuppressive regimens and evaluate immunological and non-immunological markers that may explain mechanistic differences in these agents and their effects.
The purpose of this study is to determine whether maintenance renal transplant patients receiving Myfortic can reduce or discontinue GI prophylaxis medications.
This is a multicentre, observational, non-interventional, retrospective analysis by chart review.
Current therapy to prevent organ rejection relies on the use of calcineurin inhibitors either cyclosporine or tacrolimus. Although these agents have been very successful in preventing early acute rejection, this success has not translated into improved long-term kidney transplant function. One of the important factors that leads to premature kidney transplant failure is chronic allograft nephropathy (CAN). CAN is characterized by progressive interstitial fibrosis or "scarring", vascular wall thickening, and finally glomerular sclerosis leading to slow progressive loss of kidney function. Calcineurin inhibitors have been shown to play an important role in the pathogens of CAN. Renal transplant recipients in whom calcineurin inhibitors are discontinued enjoy better and longer kidney function. Therefore, immunosuppressive strategies are being designed with the intention of withdrawing calcineurin inhibitors. The purpose of this trial is to test if tacrolimus can be safely substituted by sirolimus (Rapamycin) and this substitution will yield improved renal function, less CAN and better graft survival rates over the first year.
This study will look at the effect on long-term kidney function using tacrolimus right after a transplant and then switching to sirolimus at 3 to 5 months after the transplant.
This study is an open, randomised trial in which one group of patients (control) will receive the golden standard therapy and the other group (treatment) will receive individually adapted immunosuppression.
People with kidney transplants often develop bone disease. One reason for bone disease may be overactivity of a gland in the neck called the parathyroid gland. Overactivity of the parathyroid gland may be caused by lack of Vitamin D in the body. It has recently been discovered that many patients with kidney transplants have low Vitamin D levels. The investigators are examining the effects of doxercalciferol on parathyroid hormone levels, proteinuria and bone turnover markers in people who have had a kidney transplant.
