Filter by:The proposed pilot study challenges the current widespread paradigm of discontinuing loop diuretics when initiating chronic HD and/or maintaining the dialysate at a constant temperature of 37 °C for all patients.
Type 2 diabetes mellitus (T2DM) is associated with an increased risk of kidney failure, with high levels of glycohaemoglobin (HbA1c) presenting a sharper decline in renal function and an increase in the risk of mortality and end-stage renal disease (ESRD). Polyphenols may improve renal insufficiency in patients with diabetes with chlorogenic acids (CGA) one of the principle polyphenol groups in the diet - coffee/tea, stone fruits (especially plums/prunes) and some vegetables (artichoke, chicory). CGA (3-4 cups of coffee) has been associated with 25% lower risk of T2DM and a favourable reduction of HbA1c, blood pressure, and oxidative stress levels. This randomised controlled trial, therefore, aims to evaluate the effect of high CGA food on glycation and oxidative stress in T2DM subjects with early renal insufficiency (glomerular filtration rate of 35-60 mL/min) as well as progression of renal insufficiency and the risk of cardiovascular diseases. The study will have two phases - phase I, an interventional study of 3 months followed by phase II, an observational study of 21 months. In phase I, subjects will be randomized into 2 groups: CGA-enriched diet group, or control (habitual) diet group. The treatment group will be provided with a chlorogenic acid-rich food (coffee) with instructions to achieve an intake of 400 mg per day (equivalent to 3-4 coffee cups per day) for 12 weeks. The control group will receive a conventional coffee low in chlorogenic acid. Participants will attend three sessions during phase I; baseline, 6 weeks, and 12 weeks. At baseline, general information, medical history, dietary habits and medication use will be recorded and a Food Frequency Questionnaire completed. Urine and blood samples will be collected and blood pressure, waist circumference, height and weight recorded. Participants' diet over the previous 3 days will be assessed by estimated food diary analysis. In phase II, written dietary recommendations will be provided at three time points (months 6, 12 and 24) - treatment group to achieve a CGA-rich diet (total polyphenol intake of at least 1g per day, and at least 400mg per day of CGA) and standard dietary advice for the control group. Anthropometric/dietary data will be collected as well as blood and urine samples to assess markers of renal function, glycation and oxidative stress, and proteomic markers of cardiovascular disease, coronary artery disease and diabetes.
The purpose of this study is to characterize the effect of renal function on the PK of a 0.25 mg single oral dose of bevenopran in humans and to assess the safety and tolerability of bevenopran in patients with varying degrees of renal impairment and in healthy subjects.
Assessment of the severity of oxidative stress caused by the on-pump and off-pump cardiac surgery using mtDNA, nDNA, carbonilated proteins, nitrotyrosine, oxy-LDL, S100b-protein.
This is a pilot study which will be done in a small number of patients. The purpose of this study is to test the safety and benefit of giving a type of chemotherapy - cyclophosphamide - after the transplant to prevent graft versus host disease (GVHD) in patients with abnormal kidney function. GVHD is one of the most common complications of a stem cell transplant .
The aim of the investigators work is to describe the agreement between NIRS and ecodoppler, as monitoring systems of liver and kidney graft's perfusion in the immediate postoperative period in pediatric patients.
The purpose of this study is to validate in comparison to a reference method (inuline) two novel non-radioactive biomarkers for glomerular filtration rate (GFR) measurement in chronic-kidney disease (CKD) patients and in healthy volunteers: Calcium-EDTA and Gd-DOTA.
To evaluate changes in renal function, efficacy, and safety when switching from a combination of tenofovir/emtricitabine (TDF/FTC) plus a protease inhibitor/ritonavir (PI/r) to a combination of raltegravir (MK-0518) plus nevirapine plus lamivudine in human immunodeficiency virus (HIV)-1 infected participants with suppressed viremia and impaired renal function.
Compare Artegraft and Propaten grafts for use in dialysis access to see if one performs better than the other. How long each one lasts until a complication arises or until the graft is no longer used will be compared. The study hypothesis is that the Artegraft, being an actual blood vessel, will work better than the manufactured Propaten graft.
To collect evidence of the safety of administering donor-derived regulatory macrophage (M reg) preparations to living-donor renal transplant recipients in the context of an international European Union funded consortium aimed at evaluating cellular immunotherapy in solid organ transplantation (The ONE Study). It is anticipated that immune regulation induced by M reg therapy can eventually be used to reduce the need for conventional immunosuppression in transplant recipients.
