Filter by:The mortality and postoperative complications of high risk surgeries vary in the different series. The management of this group of patients in intensive care unit (ICU) is fundamental to improve these outcomes. The objective of this study will be to evaluate whether the use of bedside ultrasound has an impact on the management of this group of patients with a consequent reduction in the incidence of acute renal failure in ICU and, secondarily, the incidence of associated complications. All adult patients (≥ 18 years old) admitted to ICU at Hospital das Clinicas of UFMG in the immediate postoperative period of major surgery with indication of ICU monitoring will be included and randomly randomized to the control or intervention group. The control group will be conducted by the intensive care physicians in charge without the US, while the second group will be conducted based in US findings. The US protocol will consist of a pulmonary US in four windows in each hemithorax , qualitative assessment of contractility and variation of inferior vena cava diameter. The primary outcome will be the development of acute renal failure as measured by the KDIGO score. Secondary outcomes will be length of ICU and hospital stay, ICU and 28 days mortality, length spent in mechanical ventilation, accumulated water balance, noradrenaline and dobutamine dose. Serum and urinary biomarkers will also be evaluated. Key words: ultrasound, high-risk surgery, intensive care
Assessment of meropenem plasma concentration in critically ill patients who require CRRT (continuous renal replacement therapy). A standard dose of meropenem is administered, i.e. 1 gram every 8 hours.
This is a Phase 1, Multicenter, Open-Label, Parallel Group Adaptive Pharmacokinetic Single Dose Study of ISIS 681257 Subcutaneous Injections in Male And Female Subjects with Normal and Impaired Renal Function
Studies have shown that patients with chronic kidney disease in hemodialysis have a low vitamin K status which is believed to be related to an increased risk of atherosclerosis and increased bleeding tendency. The underlying causes of low vitamin K status in hemodialysis patients is unknown. Thus, the aim of this study is to investigate why hemodialysis patients have a low vitamin K status and how to improve it. This study is composed of five trials. Four of them are based on possible hypotheses to the low vitamin K status. The hypotheses are: 1. The daily intake of vitamin K is insufficient. 2. Vitamin K is removed from the blood during dialysis. 3. Absorption in the intestines is impaired. 4. The analysis method (dephosphorylated-uncarboxylated MGP) is influenced by the patients' protein intake. The purpose of the fifth trial is to investigate solutions to improve the vitamin K status of hemodialysis. One is to improve vitamin K status through diet with an increased focus on foods with high concentrations of vitamin K while considering phosphate, potassium and fluid restrictions. The second is to increase vitamin K status through a daily supplement of 360µg Menakinon-7.
The purpose of this study is to assess how fast tirzepatide gets into the blood stream and how long it takes the body to remove it in participants with impaired kidney function compared to healthy participants.
In chronic kidney disease, ESAs (Erythropoiesis-stimulating agents) are used to treat anemia. This anemia is due to decreased renal production of erythropoietin (EPO), a hormone that stimulates the production of red blood cells in the bone marrow. Treatment of anemia increases survival, decreases morbidity and improves quality of life and exercise tolerance. Self-administration of ASE has been encouraged for many years, notably with pens for injection, but only few patients are educated in the injection technique. The investigators therefore wish to lead a study in the Nephrology department of Rennes University Hospital to educate the patient, or his or her spouse, on ESA injections during hospitalization, in order to empower the patient in his care, and with the second aim of reducing the costs of chronic renal insufficiency.
This phase II, open, non-inferiority, randomized and controlled clinical trial is aimed to ascertain the incidence of contrast nephropathy in outpatients undergoing CT scan with contrast. Patients will be randomized to receive oral prophylaxis with capsules of sodium chloride and free water ingestion or prophylaxis with sodium chloride 0.9% intravenous solution. The total dose (mmol) of sodium chloride will be the same regardless administration via. The contrast will be iodixanol. Patients >65 years, of both sexes, with at least one of the following criteria: diabetes, stable heart failure or chronic kidney disease (estimated glomerular filtration rate between 30 and 60 ml/min), undergoing CT scan with contrast, and who give written informed consent, will be included in the study. Patients with estimated glomerular filtration rate <30 ml/min, serum potassium <3.5 mEq/L, infusion of iodine contrast in the previous 15 days, administration of nephrotoxic drugs in the previous 72 hours or expected in the following hours after contrast infusion, decompensated chronic conditions (heart failure, chronic obstructive pulmonary disease, hypertension), allergy to iodine contrast, or the presence of hyperchloremia or hypernatremia, will be excluded from the study. Contrast nephropathy will be defined as the increase of serum creatinine >0.3 mg/dL from baseline, or the reduction of estimated glomerular filtration rate (MDRD-4) >25% from baseline, in the first 48 hours after contrast administration.
Arterial calcifications (AC) are constant lesions in patients with Chronic Kidney Diseases (CKD). Renal transplantation would reduce their progression compared to dialysis. AC pathophysiology is a complex and finely regulated process that involves many local and systemic factors, both pro- and anti-calcification. The progression of the CKD is accompanied by an increase in phosphate levels as the renal excretion capacity of inorganic phosphates (Pi) decreases while their digestive absorption remains unchanged. Hyperphosphatremia is a well-identified calcifying factor contributing to ACs in the CKD. On the other hand, pyrophosphate (PPi) is an anti-calcifying factor from the hydrolysis of extracellular ATP by ectonucleotidases. While there are many factors that may contribute to a protective effect against AC progression of renal transplantation, no study has been yet analysed the role of PPi. Plasma concentration of PPi is decreased in dialysis patients compared to non-kidney failure patients. The main objective of this monocentric, prospective and interventional pilot study will be to compare the progression of CA and [PPi]pl between a group of renal transplant patients over the past 24 months and a group of dialysis patients over the same period of time. The secondary objectives will be to compare the progression of ACs and the ratio[PPi]pl/[Pi]pl between transplanted and dialysis patients. Transplanted patients will be included within 24 (±3) months of transplant. Dialysis patients will be included at 24 (±3) months of the CT scan performed during the pre-transplant check-up. At inclusion, all patients will benefit from a CT scan without injection and a plasma dose of PPi, Pi and other factors involved in controlling calcification.
This study aimed to investigate the efficacy of midodrine plus octreotide versus norepinephrine and to determine the predictive factors of response in patients with HRS-AKI.
Successful communication between patients, caregivers, and physicians can improve how patients feel about their treatment. Our recent studies of older dialysis patients find, however, that many patients do not engage in this type of communication about treatment options. This study aims to determine whether the Decision-Aid for Renal Therapy (DART), a web-based program, can improve shared decision-making (decisions where patients are actively engaged) among patients, caregivers, and physicians, and improve certainty and satisfaction in treatment decisions.
