NCT07337083
Prediabetes is a highly prevalent condition, affecting about one-third of adults in the United States Patients with prediabetes have an increased risk for diabetes, with 2% to 10% progressing to diabetes each yea Although prediabetes is frequently considered an intermediary stage in the progression between normoglycemia and diabetes, many individuals may have prediabetes for several years, while some may never progress.
NCT04700631
The recent discovery of extracellular vesicles (EV) as a mechanism of intercellular communication has made it possible to develop a new field of health research and could bring new information on the pathological mechanisms of renal diseases. Definition of physiologic and pathologic values of urinary extracellular vesicles (EVu) between healthy subjects and chronic kidney diseases (CKD) patients could be a new tool for follow up of renal diseases. EV are found in all biological fluids including urine, that's why they are increasingly analyzed in renal pathologies. The main objective of this study is to determine the physiological values and the pathological thresholds of EVu.

The Hemodialysis Unit of the Hospital Ramon y Cajal is a pioneer in the implementation of a program of incremental hemodialysis, starting with two sessions a week in patients with residual renal function. The main objective is to compare whether the initiation of hemodialysis with two sessions a week over conventional pattern of initiation of three sessions a week better preserves residual renal function.
NCT06347029
The vascular endothelium is an organ in its own right, playing, among other things, a primordial role in the control of vascular tone. This vascular tone is ensured by pro-dilator mediators (nitric oxide (NO), prostacyclins (PGI2)), or vasoconstrictors (endothelin, thromboxane A2 or PGH2).Uremic toxin accumulation in chronic kidney disease (CKD) is a well-known factor in endothelial dysfunction, often associated with higher cardiovascular risk. This association is also present for terminal chronic kidney disease characterized by the need to resort to an extra-renal purification technique (in-center hemodialysis (HD), daily home hemodialysis (HDQ), peritoneal dialysis) or to resort to renal transplantation. For HD to be effective, it is essential that the blood flow rate passing through the dialyzer is greater than 300ml/min. This imperative requires that any hemodialysis patient have specific vascular access (dialysis catheter or arteriovenous fistula (AVF)) to ensure these flow rates. The vascular access of choice is the arteriovenous fistula , because it is associated with a lower risk of infection and lower morbidity and mortality. Making an arteriovenous fistula consists of surgically creating an anastomosis between a vein and an artery. Complications of arteriovenous fistula are common. Arteriovenous fistula maturation may be delayed (maturation delay) or even absent. Drainage veins and/or anastomoses can also be the site of stenosis or thrombosis. The pathophysiology of these complications is complex and multifactorial. Among the risk factors for these complications (delay or absence of maturation, stenosis thrombosis), the positivity of antiphospholipid antibodies (aPL) can be cited, as well as endothelial dysfunction. Antiphospholipid syndrome (APS) is an autoimmune disease causing a thrombotic phenotype. This is an acquired thrombophilia. In the general population, the prevalence of antiphospholipid antibodies is around 0.5%; this prevalence is far from rare in hemodialysis, since it represents up to 37% in dialysis patients. In a retrospective study carried out at Brugmann University Hospital in 2023 , on 115 patients with AVF and in whom aPL dosages were available, the prevalence of persistent positivity (2 positive dosages spaced more than 12 weeks apart) was 21%. Interestingly, a third of the cohort presented an antibody profile that did not allow them to be classified according to the classification criteria in force. This group corresponds to patients with a single positive dosage, either not recontrolled or recontrolled negative. This group was called Fluctuating. This fluctuating group was associated with arteriovenous fistula complications in a 2019 study. Endothelial dysfunction is also implicated in the pathophysiology of APS. In clinical practice, the "flow mediated dilation" (FMD) test makes it possible to assess endothelial dysfunction in vivo. It involves the phenomenon of post-occlusive hyperemia which is mainly linked to NO and endothelium-dependent vasodilation. In the brachial artery, NO is the sole mediator of FMD. Endothelial dysfunction according to FMD has been described in populations with advanced chronic kidney disease, as well as patients with cardiovascular diseases. Hemodialysis patients with delayed/absence of arteriovenous fistula maturation have more pathological FMDs compared to dialysis patients without fistula problems. However, the additive role of aPL in this different population has not been studied in terms of endothelial dysfunction by FMD. The objective of this study is to evaluate the weight of antiphospholipid biology on endothelial dysfunction in hemodialysis patients, using the FMD test. 1. Compare endothelial dysfunction by FMD according to the stage of chronic kidney disease and in comparison to a control group without chronic kidney disease. 2. Characterize the FMD pre or post dialysis and according to the duration of the long (for example between Thursday and Sunday) vs. short (between Tuesday and Thursday) inter-dialytic period. 3. Evaluate the relationship between endothelial dysfunction according to FMD, aPL positivity and arteriovenous fistula complications in hemodialysis patients. 4. Evaluate the risk factors associated with endothelial dysfunction according to FMD, and in particular evaluate the impact of antiphospholipid antibodies. 5. Evaluate the correlation between endothelial dysfunction according to FMD and other markers of endothelial dysfunction (urinary NO and metabolites of urinary NO, PGI2, endothelin, PGH2).

The main objective is to assess the effects of chronic intradialytic physical exercise on myocardial remodelling and regional function.
NCT04525196
Physical inactivity is known to increase the risk of developing many diseases as cardiovascular diseases, diabetes, some cancers, and other chronic diseases. The impact of the inactivity is even higher in a fragile population as patients with Chronic Renal Failure (CRF) who need dialysis. This can lead to serious adverse events during the lifetime of these patients, such as arteriopathy which can result in amputation, deterioration of general condition, loss of independence and depression of wasting away. Despite the need to promote physical activity in this population of hemodialysis patients with CRF, little is known about the effects of a supervised physical activity conducted in these patients. With this study, the investigators propose to assess the effects of a physical activity program on several parameters, in hemodialysis subjects.
NCT05765630
The aim of this PROJECT is to develop two biomarkers to assess the thrombotic and hemorrhagic risk of patients with chronic renal failure (CKD) treated with antiplatelet drugs following the occurrence of an acute coronary syndrome (ACS). These biomarkers will help to adapt antiplatelet therapy on an individual basis (intensity, duration of antiplatelet treatment) and thus reduce the risk of thrombotic and hemorrhagic events in this particularly fragile population. The methods for measuring these two highly innovative biomarkers are currently being developed. The first biomarker corresponds to the measurement of an intraplatelet molecule, Rap1b in its active form (aRap1b). The second biomarker is the measurement of the pro-antithrombotic balance of circulating endothelial microvesicles (patEMV), a reflection of endothelial dysfunction. An automated method for biomarker measurement will be developed in partnership with the industrial partners Stago and BioCytex during the project.

NCT05353946
The current role of the rotational atherectomy is for non-dilatable coronary lesions and for severely calcified lesions that may interfere with optimal stent expansion. Severely calcified coronary lesions are associated with worse outcomes. In this regard, chronic kidney disease is associated with severely calcified coronary arteries. Some evidence suggests that elective rotational atherectomy used by experienced operators can be safe and effective, minimizing time and complications for patients with heavily calcified lesions. However, there is no direct randomized comparison between rotational atherectomy and angioplasty alone in the setting of chronic renal failure and with intravascular ultrasound assessment for detecting severely calcified coronary arteries.
NCT01604395
The purpose of this study is to evaluate the long-term safety and effectiveness of growth hormone (Eutropin Inj./Eutropin plus Inj.) treatment with GHD (Growth Hormone Deficiency), TS (Turner Syndrome),CRF (Chronic Renal Failure), SGA (Small for Gestational Age), and ISS (Idiopathic Short Stature).
NCT04089397
Sleep disorders are common in dialysis patients. At present, the management of insomnia in patients with chronic renal failure is not significantly different from that of the general population, which focuses on the management of co-factors, sleep hygiene, and cognitive-behavioral therapy. Light therapy is a paramedical practice that involves exposing a patient to a light intensity greater than 5000 Lux (usually 10,000 Lux) for 30 minutes in the morning between 7:00 and 8:30. Its impact is partly mediated by an improvement in the nycthemeral cycle of melatonin. Light therapy may improve sleep disorders and anxious-depressive elements as suggested in the literature. This technique has not yet been evaluated in dialysis patients, whereas easy to set up.
NCT03927300
The investigators proposed to conduct a retrospective study to evaluate the impact of the implementation of apTeleCare software on the management of dialysis patients at home in terms of the number and duration of hospitalizations. For this purpose, the investigators will compare patients' data over a 2-year interval before the introduction of Telemonitoring (January 2012 and December 2013 inclusive - Group 1) with patients data who have benefited from this application (between August 2016 and July 2018).
