Active clinical trials for "Renal Insufficiency, Chronic"

In health, blood pressure (BP) falls at night by >10% compared with day-time values. This natural dipping pattern is important as without it there is an increased risk of cardiovascular disease (CVD). Recent evidence suggests that chronotherapy (taking anti-hypertensive medication at bedtime instead of in the morning) may enhance nocturnal BP dipping and reduce the risk of CVD events. There is therefore an urgent need to characterise diurnal BP patterns in patients who may be at risk of reduced nocturnal dipping in order to maximise protective therapy in all those who would benefit. Similarly, it has previously been demonstrated that increased arterial stiffness is associated with increased CVD risk, however little is known about whether loss of diurnal variations in arterial stiffness confer addition risk. Kidney disease is independently associated with increased CVD events, but the exact makeup of this risk is not clear. Within this heterogenous cohort several very distinct groups exist including those with acute kidney injury (AKI), chronic kidney disease (CKD), inflammatory conditions like small vessel vasculitis (SVV), and those who have either donated or received a kidney transplant. Diurnal BP and arterial stiffness patterns within these patient groups are not well characterised. The investigators will recruit patients at increased risk of CVD from the Royal Infirmary of Edinburgh Renal and Vasculitis Clinics. Participants will undergo 24-hour ambulatory BP and arterial stiffness measurement in conjunction with day- and night-time blood and urine sampling on two separate occasions. This study aims to characterise diurnal patterns of BP and arterial stiffness in patients at increased risk of CVD and compare findings with healthy controls. In doing so, the investigators aim to allow more targeted CVD risk reduction strategies and improve long-term patient outcomes.

This prospective observational research will be conducted to assess the burden of hyperkalemia including treatment and disease burden of patients in a long-term continuous care from various aspects including adherence to the medication for hyperkalemia and HR-QoLs.

This prospective cohort study aim to investigate the ability of multiple types of assessments including 1) the modified Venous Excess Ultrasound (VExUS) assessment, 2) non-invasive estimation of absolute blood volume (ABV), and 3) change in carotid Doppler at the start of IKRT to predict IDHE in acutely ill hospitalized patients. The secondary aim will be to determine whether each modality improves the prediction of IHDE compared to the evaluation of the attending physician and whether they also predict cerebral hypoxia during IKRT measured by near-infrared spectroscopy (NIRS). Finally, detailed hemodynamic data including relative blood volume monitoring, tissue oximetry, and other parameters will be collected continuously during IKRT sessions enabling exploratory analyses aimed at identifying hemodynamic phenotypes related to IDHE during IKRT.

The corticomedullary gradient is largely responsible for developing the gradients that are needed to concentrate urine (more solutes and less water). The ability of the kidneys to produce concentrated urine is a major determinant of the ability to survive the warm weather. When temperatures are high, we lose water through sweat, and so the kidneys retain water to maintain fluidity in the blood. The maintenance of a sodium (salt) gradient is required for urine concentration because increased medullary sodium concentration increases the reabsorption of water into the kidney, to be redistributed in the blood. The purpose of this study is to know if the corticomedullary gradient is altered in patients across a wide spectrum of kidney disease using sodium Magnetic Resonance Imaging (MRI), a machine that takes pictures and measures the salt content in the kidneys. 23Na kidney MRI, will provide functional MR of the kidney as a non-invasive tool to describe medullary function to improve management of chronic and kidney disease.

CKD is a strong risk factor for cardiovascular disease and mortality , As in adults, cardiovascular disease occurs in some children with CKD before they reach ESRD as well as after

Chronic kidney disease (CKD) is a public health problem and affects about 10% of the world's adult population with a constantly increasing incidence. The approach to CKD in France is centered on access to replacement therapy (dialysis, renal transplantation), the cost of which amounts to 4 billion euros (data from the REIN registry). Real-life data are essential to specify the characteristics of patients with chronic kidney disease and the factors associated with the evolution of CKD and the occurrence of complications in order to improve the management of CKD before the suppletion stage. Since October 2019, CKD at the severe stage (stage 4) and at the non-dialysis end stage (stage 5) is subject to an annual flat fee (Article L. 162-22-6-2 of the Social Security Code). The reimbursement of these lump sums by the health insurance is subject to the collection and transmission of certain medical data by the establishments.

This study consists of two phases. The purpose of phase 1 is to identify incidence and patterns of erythropoiesis-stimulating agent (ESA) hyporesponsiveness and its associated factors in ESA treated patients. The purpose of phase 2 to identify outcomes associated with ESA hyporesponsiveness. Key aspects of the phase 2 study design will entirely depend on the results from phase 1.

Chronic kidney disease (CKD) is a progressive disease with hidden epidemics and one of the most significant contributing factors to end-stage renal disease (ESRD), cardiovascular comorbidities, cachexia and anemia, which accounts for a nearly 1.2 million populations died per year.
