Filter by:Furosemide is an old drug that has been used frequently in the postoperative period of kidney transplantation, aiming to achieve adequate urine output. There is no previous study that directly evaluate the urine response to standardized dose of furosemide in the postoperative period. The objective is to measure the urine output after standardized dose of furosemide is delivered, as a biomarker to predict the graft function in perioperative period.
The study will determine whether administration of sargramostim will improve myeloid dendritic cell deficiency in various study groups, including healthy subjects and patients with chronic kidney disease, including those with kidney transplants.
The purpose of this study is to establish an ultrasound mathematical model using acoustic radiation force impulse (ARFI) and contrast-enhanced ultrasonography (CEUS) for diagnosing the status of renal allografts.
The purpose of this study is to determine the effectiveness of behavioral feedback plus economic incentives to promote treatment adherence among a large diverse population of adolescents and young adults (AYA) with kidney transplant (KT) or spina bifida (SB).
The aim of this study is to determine if amiloride, a diuretic drug, is capable of increasing renal salt excretion, lowering blood pressure and inhibiting uPA in kidney transplant recipients with proteinuria compared to normoalbuminuric transplant patients.
This is a long-term intervention study on the effects of marine n-3 PUFAs in renal transplantation. Our hypothesis is that patients treated with marine n-3 PUFA supplementation will have less decline in kidney transplant function compared to patients treated with placebo.
Incisional negative pressure therapy (INPWT) has previously been shown in certain patient populations to decrease wound healing complications, decrease the rate of hematomas and seromas, as well as have better scar quality. We have found a group of patients, those who have panniculectomies in preparation for renal transplant, with significantly higher rates of wound healing complications. We believe the best way to demonstrate benefits of incisional negative pressure wound therapy will be in this group of patients known to have significantly higher rates of wound complications.
Demonstrate that low dose (3 mg/kg total ) rATG (thymoglobulin) has similar efficacy (delayed graft function, slow graft function, biopsy proven acute rejection episodes, infections, hospitalizations, adverse events, graft loss and death) than Basiliximab induction
Conventional vascular imaging techniques are often either contra-indicated in chronic kidney disease (CKD) patients due to their relative invasiveness, risks and cost. Computed tomography angiography (CTA) requires radiation and nephrotoxic iodinated contrast which may precipitate significant worsening of renal function and even prompt the need for institution of dialysis. Magnetic resonance angiography (MRA) using gadolinium-based contrast agents has been associated with the rare disease nephrogenic systemic fibrosis. Alternative imaging methods also have drawbacks: for example, this frail patient group has a higher risk of complications from conventional invasive catheter-based angiography, non-contrast-enhanced MRA allows visualization of smaller arteries but is less accurate for larger vascular structures, and ultrasound is often not appropriate for evaluation of the deep vessels of the abdomen and pelvis. Ferumoxytol is an ultrasmall superparamagnetic iron oxide particle encapsulated by a semisynthetic carbohydrate, which was initially developed as a magnetic resonance imaging (MRI) contrast agent in 2000. However, interest in ferumoxytol as a therapeutic agent for the treatment of iron deficiency anaemia in the setting of CKD eclipsed its use as MRI contrast agent. During the last decade, ferumoxytol has gained appeal as an MRI contrast agent in patients with estimated glomerular filtration rates <30mL/min and there are reports in the literature for its safe use and utility in both adult and pediatric patients with CKD. Participants will be selected from those who have been referred for assessment prior to kidney transplant or prior to vascular access creation for haemodialysis and will be divided into three groups. The first group will include patients who will undergo a CTA of abdominal and aortoiliac vasculature as part of their preparation for potential kidney transplantation. The second and third groups will include patients who are having a fistula or a graft created for dialysis, respectively. These patients are routinely having US vascular mapping to visualise the blood vessels before a fistula or a graft is created. Additionally, patients included in the second and third groups are routinely having surveillance scans of their fistula or graft at 6 weeks following creation. Study participants undergoing standard imaging tests as part of their clinical care will also have ferumoxytol-enhanced MRA (FeMRA).
The purpose of this proof of concept, pilot study is to determine whether the unique combination of the human immunodeficiency virus (HIV) co-receptor antagonist, Maraviroc, and the mammalian target of rapamycin (mTOR) inhibitor, Sirolimus, in HIV-infected kidney transplant recipients has an impact on chemokine receptor 5 (CCR5) density, the HIV-reservoir, or rejection of the transplanted kidney. 15 HIV-infected kidney transplant recipients will be recruited and their immunosuppressant regimen will be changed to include an mTOR inhibitor (such as Sirolimus) unless they are already on one. In addition, Maraviroc will be added to their HIV regimen, unless they are already on Maraviroc. Blood will be taken to measure markers of the HIV reservoir, their CCR5 density and expression, and immune activation.
