Active clinical trials for "Renal Insufficiency, Chronic"

Context and hypothesis: The prevalence of diabetes mellitus keeps going to increase, due to the ageing of the population and the high prevalence of overweight and obesity. Thus about 5% of the French population is said to have diabetes according to the national health insurance reimbursement data estimations. 15 to 20% of diabetic patients will have a foot chronic ulcer in their lifetime. Nowadays, diabetes is still the leading cause of non-traumatic amputation in France, amputation being very often preceded by a trophic disorder. Thus, the person with diabetes has a 7-fold risk of amputation. For the year 2013, in France, incidence rates of hospitalizations for lower limb amputations and foot wounds in the diabetic population were 252/100000 and 668/100000 respectively. In an attempt to prevent the risk of foot wounds in people with diabetes, the International Working Group on the Diabetic Foot (IWGDF) has established foot grades associated with an increased risk of foot wounds. These grades are now used by health authorities to calibrate their care offer such as reimbursements for podiatry care. Chronic kidney disease is one of the major complications of diabetes. In 2013, according to data from the French registry (REIN), 4,856 diabetics started renal replacement therapy in 2016, representing 46% of the newly dialyzed population. This represents a relative risk 9.2 times higher than in the general population. The Investigators hypothesize that beyond the risk of wound, there is a link between the stage of chronic renal disease and the risk of foot ulcer grade as defined by the IWGDF. The link between chronic renal disease and this common marker of foot risk has never been studied to our knowledge. The long-term objective, beyond this study, is to improve patient pathways and thus improve the prevention of foot wounds in diabetics with renal insufficiency. This is all the more true since prevention actions in the dialysis population have already shown their effectiveness on a large scale on the risk of amputation. Protocol : All patients with a diabetes mellitus who consult diabetology and nephrology services at the Montpellier University Hospital will be included in this study. The consultation wil be the same as usual. The Investigators will ask for the history of diabetes, the history of complications, the current treatments and the Investigators will make a standardized clinical examination of feet with a foot risk gradation according to the IWGDF.The investigators will report the standard biologicals values.

Hemodynamic trends will be assessed using the device, in 100 dialysis sessions in 30 patients, who are prone to develop hypotensive episode during dialysis. Sitting blood pressures will be measured immediately prior to each hemodynamic measurement: before initiation of dialysis, every each hour and in the beginning of hypotension episode, just before the end and 10 min after the end of the treatment. Gender, age, height, weight, electrode location and blood pressure data will be entered into the device. The device will measure and calculate hemodynamic parameters on each heart beat during 60 s and provides the averaged parameters. Technology for hemodynamic measurements: The device (NICaS, NI Medical) is a noninvasive regional bioimpedance cardiac measurement and analysis system (FDA 510k clearance no. K080941, 12 June 2009). The US Food and Drug Administration indication for use of the device states 'NICaS is intended to monitor and display hemodynamic parameters in males and females with known or suspected cardiac disorders needing cardiac assessment'. SV will be measured by applying an alternating electrical current of 1.4mA at 30 kHz frequency through the patient's body via two pairs of tetrapolar sensors, one pair placed on the wrist of the nonaccess arm above the radial pulse and the other pair on the contralateral ankle above the posterior tibial pulse (Figure 1). Figure 1 : Sensor location SV is calculated by Frinerman's formula: SV¼(dR/R) - q - (L2/Ri) - (ab)/b - KW - HF [2-4], where dR is the impedance change in the arterial system as a result of intraarterial expansion during systole, R is basal resistance, q is blood electrical resistance, L is the patient's height, Ri is basal resistance corrected for gender and age, KWis the correction of weight according to ideal values, HF is a hydration factor that takes into account the ratio between R and body mass index (BMI), which is correlated to body water volume, ab is the electrocardiogram (ECG) R-R wave interval and b is the diastolic time interval. SV is automatically calculated every 20 s and is the average of three measurements obtained consecutively during 60 s of monitoring. The SV index is calculated as SV/body surface area using the Du Bois formula [11]. Heart rate is calculated from a one channel ECG and cardiac (output) index¼SV index - heart rate/1000. Using an oscillometric method, sitting systolic and diastolic blood pressure measurements were made automatically by the dialysis machine. Mean arterial pressure [2 - (diastolicsystolic)/3], cardiac power index [CPI; mean arterial pressure (MAP) -cardiac index - 0.0022 w/m2; normal range 0.45-0.85w/m2] [12, 13] and total peripheral resistance (MAP/ cardiac index - 80 dyn - s/cm5 - m2; normal range 1600-3000 dyn - s/cm5- m2) [13] will be calculated. As the device measures pulsatile flow and is blinded to constant flow, fluid removal during dialysis has no impact on measurement accuracy. This was recently validated by correlating SV to ECG measurements during hemodialysis treatments. Good correlation was maintained during treatment. Further, NICaS performance immunity to fluid reduction was demonstrated by the maintenance of correlation to ECG results throughout dialysis treatments [9]. The results are drawn on hemodynamic graphs showing the MAP (y-axis) as a function of cardiac index (x-axis); curves of total peripheral resistance index (TPRI) and CPI are displayed. Ranges for the normal population are depicted by a dotted octagon.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are the newest class of orally drugs for the treatment of type 2 diabetes. These drugs decrease plasma glucose levels by inhibiting its reabsorption in the proximal tubules of the kidney. They have an attractive clinical efficacy profile, including glycemic control, weight loss, and lowering blood pressure. SGLT2 inhibitors have also been reported to reduce the risk of severe adverse cardiovascular events and progression of diabetic kidney disease. SGLT2 is expressed in the kidney, while its expression in other tissues is most likely negligible or absent. SGLT2 dilates the supply vessels to the glomerulus thereby promoting hyperfiltration. In animal models SGLT2 has been shown to reduce the excretion of macular dense adenosine, which may contribute to the excessive glomerular filtration rate as a result of vasodilation of the afferent vessels. Adenosine, unlike other vascular regions, increases the tension in the walls of the vessels supplying blood to the glomerulus. The role of adenosine in humans in this regard is poorly defined, although treatment with empagliflozin has recently been shown to increase the urinary excretion of adenosine in type 1 diabetic patients with controlled hyperglycemia. Our working hypothesis is that the SGLT2 inhibitor empagliflozin may reduce the hyperfiltration of residual nephrons by increasing adenosine production, which affects the contraction of the afferent arterioles, and this effect occurs in various types of nephropathy. In addition, it has been described that SGLT2 inhibitors may affect individual parameters of calcium-phosphate metabolism, leading to changes in bone mineral density and an increase in bone resorption marker SGLT2 inhibitors also stimulate renal, proximal phosphate reabsorption. Increased phosphate reabsorption triggers the secretion of fibroblast growth factor 23 (FGF23). FGF23 inhibits the production of 1,25-dihydroxyvitamin D (the biologically active form of vitamin D), which reduces the absorption of calcium from the gastrointestinal tract, thereby stimulating the secretion of parathyroid hormone (PTH). In the conducted studies, it was found that SGLT2 inhibitors increase the concentration of serum phosphorus, FGF23 in the plasma and PTH in the plasma, while lowering the level of 1,25-dihydroxyvitamin D.

The objectives of the Clinical Validation Through Analytical Study With Urine Samples to Compare the Effectiveness and Security of an Intelligent Device are: 1.To evaluate the performance of S-There Device in comparison to the golden standard used in the lab.

The primary objective of this study is to assess the pharmacokinetics of a single oral dose of apixaban (5mg) in participants with dialysis peritoneal versus participants with normal renal function.

This is a multi-national, observational study program using secondary data sources to address research questions related to 1) real-world dapagliflozin utilisation in CKD and potential for further utilisation, 2), the current CKD treatment landscape and 3) real-world effectiveness of dapagliflozin in CKD (pending feasibility assessment).

This is an observational study in which patients with chronic kidney diseases (CKD), type 2 diabetes (T2D) or heart failure (HF) who are current or past users of sMRA therapies are studied. sMRA stands for steroidal mineralocorticoid receptor antagonists. CKD is a long-term, progressive decrease in the kidneys' ability to work properly. Type 2 diabetes is a condition in which the body does not make enough of a hormone called insulin or does not use insulin well resulting in high blood sugar levels. HF is a condition in which the heart does not pump blood as well as it should. The renin-angiotensin-aldosterone system (RAAS) is a hormone system that works with the kidneys to control blood pressure and the balance of fluid and electrolytes (like salt) in the blood. The RAAS has been a treatment target of heart and kidney diseases for decades. One of these classes of medications is called mineralocorticoid receptor (MR) antagonists (MRAs). MRAs work to directly block the action of a hormone called aldosterone. Aldosterone is produced naturally by the adrenal glands, and it can increase the blood volume and blood pressure. Using MRAs therapies can help prevent strokes, heart attacks and kidney problems. Spironolactone was the first available MRA in the US with its approval in 1960. Eplerenone is another MRA which has been available since 2002. Both spironolactone and eplerenone are known as steroidal MRA (sMRA) due to their chemical structures. The main purpose of this study is to collect more data on the characteristics of patients who are taking sMRA currently and those who have discontinued sMRA therapy in the past 12 months. To do this, patients who have received sMRA in the most recent 12 months will be invited to participate in the study and asked to complete surveys if they agree to join the study. Patients will be found from administrative claims in a database called HealthCore Integrated Research Database (HIRD). And the other purposes of the study are to learn more about: the indications for sMRA therapy the frequency and symptoms of reported side effects of sMRA treatment the treatment satisfaction and effectiveness as well as potential reasons for treatment continuation/discontinuation of sMRA therapies Besides this data collection, no further tests or examinations are planned in this study. The participants will receive their treatments as prescribed by their doctors during routine practice according to the approved product information. Researchers will look at the health information from adult men and women in the US only if applicable who are current/past users of sMRA therapies with diagnosis of CKD or T2D or HF, consent to participate in the study.

The purpose of this study is to characterise the patient and disease profile under the influence of a protein-restricted diet supplemented with keto acids/amino acids (KA/AA), focusing on the progression of chronic renal insufficiency, calcium and phosphorus metabolism, nutritional status, patient compliance to diet and Ketosteril intake as well as the persistent dietary education to ensure compliance in a large group of pre-dialysis patients.
