Filter by:This study is being done to compare arteriosclerotic cardiovascular disease in kidney transplant recipient taking a standard multivitamin versus those taking a multivitamin augmented by a high dose combination of folic acid, vitamin B12, and vitamin B6.
The purpose of the study is to show the efficacy of reduction of cyclosporine A exposure measured by the area under the curve by Bayesian estimator on the primary prevention of degradation of the renal function in renal transplant recipients
Adherence to medical regimens refers to what degree a patient chooses to follow the advice given by his/her healthcare provider. Good adherence typically involves behaviors such as the patient taking medication as directed and going to scheduled clinic appointments. As many patients often do not follow the advice of doctors as closely as suggested, many researchers have tried to find out the reasons behind patients being "non-adherent." This research has looked at medical conditions such as diabetes, cystic fibrosis, and asthma. More recently, researchers have started to look at adherence with children who have undergone solid organ transplantation. This is because about 50% of these children are to some degree non-adherent with their medical regimen. This comes at a costly price as ongoing non-adherence in pediatric transplant can lead to the child's body rejecting the new organ and even death. This study has been designed to look at the reasons that pediatric patients may choose to be non-adherent. This study will look at issues related to the patient (e.g., age, family support), related to the disease and regimen (e.g., length of illness, how complicated the regimen is), related to the medication (e.g., taste, side effects), related to their mind (e.g., memory problems, confusion), and related to their emotions (e.g., being depressed, anxious). The investigators will be looking at each regimen-related behavior, such as attending clinic appointments and will be asking each family about any barriers that make it difficult. The investigators hope that knowing these barriers will help them make interventions that fit the specific issues that each patient faces. Ultimately, doctors, transplant coordinators, and psychological professionals will be able to use this information to intervene early with families who report barriers that impact adherence.
Acute rejection is still a major risk factor affecting the prognosis of kidney transplant patients. Alloreactive cells of the recipient infiltrate the kidney graft and cause inflammatory reaction which damages the graft structure and function. Conventional diagnosis of acute rejection is based on clinical symptoms and kidney biopsy examination. The clinical symptoms are a result of the kidney damage, which occurs days after the initiation of the rejection reaction. Kidney biopsy is an invasive and expensive procedure. It has been wished to have new parameters that can replace/supplement the conventional procedures. Chemokines are small molecules that attract inflammatory cells. Changes of chemokine levels in the urine may correlate with the immune status in the kidney. A systematic study to evaluate the chemokine levels in urine and correlation with the kidney biopsy pathology will answer the question whether monitoring of urinary chemokines would be useful in predicting graft rejection/damage.
Correction of anaemia in renal transplant recipients by parenteral application of recombinant erythropoietin and if necessary iron will improve large artery function (endothelial function and elasticity), as assessed by ultrasound techniques and applanation tonometry. The changes in large artery function will be reflected by changes in serological markers of endothelial function and oxidative stress and by changes in monocyte function and apoptosis. There are gender differences in the responses of vascular function to correction of anemia. Besides improvement of large artery function, correction of anemia will also affect parameters of graft function, i.e. glomerular and tubular proteinuria.
The purpose of this study is to compare the kidney function in patients who have received a transplanted kidney and were treated with the combination of sirolimus, daclizumab, mycophenolate and corticosteroids versus transplanted patients treated with cyclosporine, mycophenolate and corticosteroids.
The purpose of this study is to evaluate and to compare the efficacy and safety of a triple modified release tacrolimus FK506E (MR4) / MMF / steroid regimen with a triple standard tacrolimus FK506 / MMF / steroid regimen in patients undergoing kidney transplantation. It shall be demonstrated that FK506E (MR4) is non-inferior to FK506 with regards to the primary endpoint.
A dose finding study to evaluate the safety and effectiveness of FK778 in kidney transplant patients
African Americans receiving a kidney transplant are considered at high risk for early rejection of their transplanted kidney and require more immunosuppression to maintain their kidney transplant function. This increase in immunosuppression puts this group at risk for drug-related toxicities and complications such as post-transplant diabetes. This study will evaluate: 1. Whether a sirolimus based steroid avoidance regimen in African Americans may decrease the risks of drug-related toxicities, 2. Decreased rates of metabolic complications such as post-transplant diabetes, 3. The effect of Sirolimus plus a reduced dose cyclosporine on renal allograft function.
The primary objective of this study is to determine whether a clinically significant PK drug interaction ( a 30% difference in the AUC of MPA) exists between mycophenolate mofetil (under steady state conditions) and VGCV in renal and cardiac transplant recipients. This study will provide clinically relevant information to the transplant community. It will more clearly delineate whether a clinically significant PK drug interaction exists between mycophenolate mofetil (under steady-state conditions)and VGCV. Given the established dose/efficacy relationship of both MMF and VGCV, this study will provide improved dosing guidelines and potentially avoid adverse outcomes due to empiric dosage adjustments.
