Filter by:The incidence of hemodynamically relevant dialysis fistula stenoses/obstructions after 1 year is between 60-90% (from 62.5 to 91% radiocephalic, brachiocephalic 70-84%, PTFE shunts 62-87%), necessitating a therapeutic measure to preserve dialysis access during this period in 1/3 of the patients. This therapeutic measure is a dilatation of the stenosis using a standard PTA balloon (POBA, plain old balloon angioplasty with a primary technical success rate of 50-79% [2-4].In turn, in 21-50% of the cases an insufficient PTA result is obtained (so-called POBA-resistant stenosis). In these cases, predilatation with a so-called cutting balloon (carrying with small knives on its surface) is performed, leading to a success rate of 89%. However, a problem is the high incidence of restenosis, which is about 40% for recurrent stenosis and over 10% in de novo stenosis. The use of drug-coated balloon (DCB) in non-POBA resistant stenoses lead to a reduction in the restenosis rate of 35% to 5%. However, the effect of DCB in POBA resistant stenoses is unknown. Therefore, the aim of this study is to evaluate the clinical benefit of the combined use of a cutting balloon and a drug-coated balloon in POBA resistant dialysis fistula stenoses compared to the sole use of a cutting balloon.
This multiple-center, nonrandomized, open label, parallel group, single dose study will be conducted in male and female subjects with normal renal function or severe (eGFR <30 mL/min/1.73 m2) renal impairment to evaluate the effect of renal impairment on the pharmacokinetics (PK) of TD 4208.
In this study, the recent trends in outcomes according to the dialysis modality in Korea since 2009, the effect of the use of peritoneal dialysis solutions containing icodextrin or high-glucose on various outcomes, the usefulness of 'PD first strategy', and the economic burden according to the dialysis modality will be investigated retrospectively using the Korean Health Insurance Review and Assessment Service (HIRA) database.
It is known that volatile anesthesia, such as sevoflurane, retain water and that this appears more pronounced in children. However, the mechanisms for this effect is unknown and it is not clear if the commonly used anesthetic propofol does the same. In this study the investigators want to compare the fluid and electrolyte conserving effects of sevoflurane and propofol in a pediatric setting and also investigate humoral changes induced by these anesthetics.
In this study, the investigators will conduct a randomized, controlled trial to evaluate the impact of offering mobile secure text messaging on clinical outcomes.
The general aim of the present study is to test a cell therapy with third-party ex-vivo expanded bone marrow-derived mesenchymal stromal cells (MSCs) as a strategy to induce tolerance in kidney transplant recipients with a deceased donor. MSCs will be prepared accordingly to established protocols, starting from the remnants in the bag and filter at the end of the bone marrow infusions. From these samples, MSCs will be expanded in good manufacturing practice (GMP) approved facilities and used for the present study in patients undergoing kidney transplantation. The proposed study will be developed in two phases: i) a pilot explorative safety/biologic-mechanistic phase (Phase A), ii) a pilot efficacy phase (Phase B).
A phase- I clinical trial to determine safety and feasibilty of intravenous administration of mitomycin C-treated donor peripheral blood mononuclear cells in patients with chronic kidney disease stage KDIGO 4 or 5 (i.e. GFR 15-30 mL/min or < 15 mL/min) who receive a kidney transplant from a living donor.
In this study hemodialysis patients that underwent dialysis thrice weekly screen for uremic pruritus and 80 patients that at least have refractive pruritus that lead to sleep and daily activity disorders enroll in this study. These patients should have at least a course of therapy without proper response. After proper informing patients and taking testimonial patients enter to study. Then patients randomized in case and control group. In case group, patients took montelukast 10 milligram daily and in control group took placebo for 30 days. Other antipruritic or antiinflammatory medication has been stopped one week prior to starting treatment. Calcium, phosphorous, urea, creatinine, highly sensitive CRP (hsCRP), Parathyroid Hormone (PTH), hemoglobin and kt/V were measured at beginning and at end of study. pruritus severity assessed by Detailed Pruritus Score that introduced by Duo and Visual Analogue Score in beginning and at end of study in both group. Sleep disorder score and its severity added to crude score at beginning and end of study and change of measures analyzed.
This prospective interventional study aims to compare sevoflurane and desflurane anesthetic agents on regulatory T cell (Treg) numbers and its cytokine production in patients undergoing Living Donor Kidney Transplant (LDKT).
This study consists of two substudies. The first substudy: 'Renal resistive index in critically ill patients with cardiogenic and septic shock' Design: cross-sectional observational Aim of this project is: 1. to determine whether critically ill patients with cardiogenic and septic shock have an elevated Renal Resistive Index and 2. to determine whether Renal Resistive Index differs between cardiogenic/hypovolemic shock and shock due to sepsis/systemic inflammation (SIRS) 3. to determine the relation between the (change in) renal vascular resistance and - Markers of the systemic - and the microcirculation - Fluid status as quantified by bioimpedance analysis - Concomitant renal function The second substudy: 'Predictive value of the Renal Resistive Index on ICU admission and its course for the development of acute kidney injury in critically ill patients with cardiogenic and septic shock' Design: longitudinal observational The aim of this project is: 1. to determine whether the renal resistance index on admission to the intensive care unit can predict the development of acute kidney injury (AKI) in critically ill patients with shock 2. to investigate if the renal resistance index on admission to the intensive care unit is an independent predictor of the development of AKI or depends on the severity and duration of shock and other known risk factors of AKI such as comorbidity and use of nephrotoxic drugs Aim of the large research project is to determine whether the Renal Resistive Index could become a monitoring tool for intervention studies aiming to prevent acute kidney injury or protect the kidney.
