Evaluation of a Third and Fourth Dose of StaphVAX® in Adults With End-Stage Renal Disease
Staphylococcal InfectionsChronic Kidney FailureThis study is a continued evaluation of the immune response to StaphVAX , a Staphylococcus aureus type 5 and 8 capsular polysaccharide conjugate vaccine, in end-stage renal disease patients, by giving a 3rd and 4th dose to a subset of the participants in the previous efficacy trial. Participants continue to receive the vaccine or placebo in a blinded manner, and are also randomly assigned to 1 of 2 different intervals between the doses. The immunogenicity is measured by the antibodies in the blood, and typical vaccine safety information is also collected.
Rapamycin Use in Calcineurin Inhibitor (CNI)-Free Immunosuppression for Stabilization/Improvement...
Heart TransplantationRenal FailureClinical Problem: Renal insufficiency after heart transplantation caused by cyclosporine medication was addressed. Current therapeutic approaches include cyclosporine reduction or discontinuation. It is unclear whether discontinuation of low dose cyclosporine also has a beneficial effect, i.e. is there a threshold effect for cyclosporine nephrotoxicity? Study Design: Heart transplant patients with a moderate degree of renal failure on low dose cyclosporine were randomized to either a) no change; or b) discontinuation of cyclosporine and initiation of rapamycin immunosuppression. Read-Out: Renal function after 6 months; tolerability; and safety were assessed.

Iron Sucrose in Stage 3/4 Kidney Disease
Kidney FailureAnemiaOne of the complications of late stage kidney disease is the development of a low red blood cell count (anaemia/low haemoglobin concentration). The Australian Commonwealth government limits funding of medications (called erythropoietic stimulating agents) to those patients who have already developed anaemia. There is evidence supporting the beneficial effects of maintaining a higher haemoglobin in these patients. Higher haemoglobin can delay the onset of dialysis and reduce the development of heart enlargement. However, the administration of erythropoietic stimulating agents is not without risk, including a high financial burden, worsening of high blood pressure and a rare complication called pure red cell aplasia. Previous studies have shown that patients with chronic kidney disease require additional iron to maintain the production of red blood cells. Thus it would be timely to determine if the administration of iron sucrose to these patients can maintain a near normal haemoglobin concentration, without the need to start an erythropoietic stimulating agent and possibly delaying dialysis. Study Hypothesis: That administration of iron sucrose is superior to standard care in the prevention of anaemia in patients with stage 3 /4 kidney disease.
Acute Renal Failure Trial Network (ATN) Study
Acute Renal FailureThis is a multi-center, prospective, randomized, parallel-group trial of an intensive strategy vs conventional strategy of renal replacement therapy for the treatment of acute renal failure secondary to acute tubular necrosis in critically ill patients. The primary hypothesis is that the intensive strategy will reduce 60-day all cause mortality by 10% compared to the conventional strategy - i.e.,a reduction from 55% in the conventional arm to 45% in the intensive arm. Secondary outcomes are 60-day in-hospital all-cause mortality, 1-year all cause mortality, and recovery of renal function by day 28. The study will recruit 1164 patients over a period of 3 years, 8 months and each patient will be actively followed for 60 days.

Multi-parametric MRI Evaluation of Renal Graft Performance After Living Donor Donation.
Renal InsufficiencyChronicThe selection of kidneys from living donors is based on strict glomerular filtration rate (GFR) values, in the setting of the increasing proportion of older donors. The 2017 KDIGO recommendations consider that approving kidney donation for a donor with a GFR between 60 and 89 mL/min/1.73 m² should be individually discussed, possibly using a calculator. A GFR < 60 mL/min/1.73 m² should contraindicate donation without considering the donor's age. GFR physiologically decreases with age, so older donors frequently have a GFR below 90 ml/min/1.73 m². However, the proportion of older donors continues to rise. Kidney grafts from older living donors maintain better renal function than those from deceased donors, aiming to counteract the organ shortage. Kidneys possess functional reserves, allowing an increase in GFR during stimulations and adaptation to reduced functional nephron count (as after nephrectomy). Assessing this adaptive capacity clinically is challenging. It might be dependent on vascularization and/or absence of fibrosis, but these parameters are poorly understood due to a lack of current in vivo exploration methods. The development of functional renal MRI enables the evaluation of these parameters, allowing measurements on separate, regional, non-invasive, quantitative kidney segments coupled with morphological studies. BOLD-MRI can measure regional oxygen content, thus accessing more precise medullary data. The DWI sequence can estimate renal microstructure and study interstitial fibrosis. Therefore, evaluating renal performance (by measuring GFR, renal perfusion, fibrosis, inflammation, and oxygen content) in donors, and studying the evolution of these parameters in recipients and donors, could optimize donor selection. Hence, the aim of our study is to 1) investigate the evolution of renal functional parameters in the transplanted kidney up to 1 year post-transplant, and 2) study the evolution of these same parameters in the contralateral kidney of the donor.
Effects of a Mindfulness-based Intervention in Stress, Pain and Quality of Life in People Undergoing...
Renal InsufficiencyChronic7 moreThis project has as main objective to evaluate the effects of a Mindfulness-based intervention (MBI) in the reduction of stressors, pain and quality of life of people with chronic kidney disease undergoing hemodialysis (HD). The investigators hypothesize that this program offered during hemodialysis sessions may modify the pain profile, stressors levels and may improve the quality of life by the people in hemodialysis. This is an incipient field of research at the international level and almost nonexistent in Brazil. Evidence indicates the need for MBIs to be performed during HD sessions, adapted to the context, to facilitate patient compliance, contribute to the management of the discomfort generated during HD and promote health.
