NCT05491642
Researchers are looking for a better way to treat people who have chronic kidney disease (CKD), a progressive decrease in the kidneys' ability to work properly. In people with CKD, the kidneys do not remove wastes and extra fluid from the blood as well as they should. High blood pressure makes it more likely that the CKD gets worse. The study treatment BAY3283142 is under development for treating CKD. It activates a protein called soluble guanylate cyclase (sGC) that generates cGMP - a molecule that relaxes blood vessels and is thought to have beneficial effects in CKD. The participants do not benefit from this study. However, the study will provide information on how to use BAY3283142 in subsequent studies in people with CKD. As many people with CKD do also suffer from high blood pressure, this study is done in people with mild to moderate high blood pressure to safeguard the use of BAY3283142 in people with CKD in later studies. The main purpose of this study is to learn how safe different single and multiple doses of the study treatment BAY3283142 are compared to placebo in male and female participants (after menopause) with mild to moderate high blood pressure. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To answer this, the researchers will compare the number of participants who have medical problems after taking BAY3283142 to those treated with placebo. Doctors keep track of all medical problems that happen in studies, even if they do not think they might be related to the study treatments. Dependent on the treatment group, the participants will either take BAY3283142 or placebo as tablet once or twice a day. Patients will take one dose for 6 days and will then be switched to a higher dose for additional 6 days. In summary, three different dose combinations consisting of two different doses each will be tested. Participants will be in the study for up to 7 weeks, including 12 treatment days (6 per dose step). They will stay in-house for 17 days starting two days before intake of the study treatment. In addition, one visit before and one visit after the in-house phase to the study site is planned. During the study, the study team will: * Check vital signs * Take blood and urine samples * Examine the participants' heart health using electrocardiogram (ECG)
NCT05860309

NCT03578510
Intradialytic hypotension (IDH) is a frequent and serious complication that may occur during hemodialysis treatment. The investigators and others have shown that the Hemocontrol biofeedback system is associated with improved hemodynamic stability. Hemocontrol is a technique that guides the patients' blood volume along a pre-set trajectory by continuously adjusting the ultrafiltration rate and dialysate conductivity. In a recent pilotstudy, the investigators found significantly higher plasma vasopressin levels during the first hour of dialysis with Hemocontrol in comparison with standard hemodialysis. Increased vasopressin levels may contribute to intradialytic hemodynamic stability during hemodialysis by enhanced vasoconstriction. These results, however, did not prove directly that the improved hemodynamic stability with Hemocontrol is indeed caused by higher initial plasma vasopressin levels. Alternative explanations might be that 1) the higher initial plasma sodium levels with Hemocontrol dialysis enhance activity of the sympathetic nervous system directly, causing vasoconstriction and thereby improved hemodynamic stability and/or 2) that the higher initial plasma levels of sodium in Hemocontrol inhibit the release of nitric oxide by the vascular endothelium. Another goal of this study is to investigate whether vasopressin is removed with hemodialysis.
NCT05434286
Point-of-care echocardiography (POC-Echo) is used to determine left ventricular systolic and diastolic dysfunction (LVDD), inferior vena cava (IVC) dynamics and volume status in cirrhosis and Acute-on-chronic liver failure ACLF accurately. We will assess IVC dynamics, LV systolic function \[LV ejection fraction (EF) \& cardiac output (CO)\], and diastolic dysfunction (E/e', e' and E/A ratio) and urinary biomarkers (cystatin C and NGAL) in patients with cirrhosis and ACLF with hepatorenal syndrome-acute kidney injury (HRS-AKI).
NCT05727579
SGLT2 inhibitors such as ertugliflozin improve blood pressure and kidney outcomes in people living with diabetes through incompletely understood mechanisms, however, not all patients treated with SGLT2 inhibition have improved outcomes. Changes in kidney sodium handling is among the mechanisms by which SGLT2 inhibition may reduce blood pressure and drive beneficial kidney outcomes. This process is heavily dependent on daily sodium intake by patients receiving SGLT2 inhibitor treatment. In this study, the effect of daily sodium intake on SGLT2-inhibitor induced physiological effect is studied, including blood pressure regulation and kidney physiology.

NCT02049827
Kidney transplantation is the treatment of choice for end stage renal disease (ESRD) improving the quantity and quality of life for dialysis patients. Although prolongation of graft survival in the short term by preventing the release is observed by immunosuppression (IS) powerful, the longer-term survival has not improved . Indeed, the IS can not only have a direct deleterious effect on the kidney transplant , but too weak IS can promote rejection, and too strong, promote the emergence of a viral disease polyomavirus BK ( BKV ) . BK nephropathy (BKVAN ) virus is accompanied by an irreversible impairment of the renal function , leading to a loss of the graft followed by a premature return to dialysis in at least 50 % of cases. Plasma BKV reactivation was observed mainly during the first year of transplantation in 15% of patients and complications annually BKVAN concern about 5 % of recipients . Currently , treatment options are very limited , only the decrease in IS shows a partially effective when care is early . There is no specific antiviral effective treatment of this disease . In addition, there is no way to predict which patients will develop BKV reactivation BKVAN despite lower tax. The diagnosis of interstitial nephritis BKV based on the detection of viral DNA by PCR and plasma is confirmed by histological analysis of renal tissue . Plasma quantitative PCR ( qPCR) to measure the progression of the disease and therapeutic efficacy. Control of BKV viremia is the direct antiviral immune response quality based primarily on a very effective anti- T lymphocyte activity BKV reflection. In this context, the inhibition of lymphocyte activation induced by IS blocks the establishment of T-cell responses anti- BKV in most transplant, a very low presence of T lymphocytes is generally observed in these patients anti- BKV (LYT - BKV) blood . Our preliminary studies have validated in vitro a sensitive test to measure the functionality of blood LYT - BKV. This test is used to evaluate the concentration and functionality of LYT - BKV present in small volume of blood by measuring their specific proliferation after stimulation with peptide cocktails BKV. Proof of concept of the feasibility of this test was established on a small series of samples and highlights significant differences in lymphocyte anti-BKV different patients. Put to good use during the post-transplant follow-up, this type of test can provide the clinician with valuable data to assess the quality of anti- BKV T response compared to the intensity and type of IS treatment. Early identification of patients at risk of reactivation of BKV, or at risk of BKVAN if BKV viremia observed , would adapt the therapeutic response and monitoring arrangements at the fair. The objective of this project is to conduct a feasibility study to assess the relevance of post-transplant monitoring of anti- BKV T response of BKV viremic patients during the first year post- transplant. Immunological data will be analyzed in relation to virological data and bioclinical data.

NCT01515605
Molecular monitoring is conducted in blood cells, plasma samples, urine samples and/or tissue from patients after kidney transplantation. In the present study the investigators examine the hypothesis that noninvasive diagnostic molecular monitoring can improve the outcome after transplantation. Routine clinical and laboratory data from serum and urine are evaluated at baseline and after 0-1-2-3-4-12-16-52 weeks and 1-2-3-4-5-6-7-8-9-10 years after kidney transplantation. Mononuclear cells were obtained from the blood and transcripts of several diagnostic genes (including GATA3 (Trans-acting T-cell-specific transcription factor3), GATA4 (Trans-acting T-cell-specific transcription factor4), GAPDH (Glyceraldehyde 3-phosphate dehydrogenase), TRPC3 (Transient receptor potential cononical type3), TRPC6 (Transient receptor potential cononical type6), granzyme B, perforin, FOXP3 (Forkhead box P3), ISG15 (Interferon-stimulated gene 15), Mx1 (Interferon-induced GTP-binding protein), MMP3 (Matrix metalloproteinase-3), MMP9 (Matrix metalloproteinase-9), long-non-coding RNA, and others) are quantified using standard quantitative RT-PCR (Reverse transcription polymerase chain reaction) techniques. Proteomic analysis were performed in plasma and urine samples. Polymorphisms of selected genes are analyzed using standard techniques. Data are analyzed by descriptive statistics. Differences between groups were analyzed using Mann-Whitney test or Kruskal-Wallis-test and Dunn's multiple comparison post-test, as appropriate. Associations between variables are analyzed using regression analyses. Contingency tables are analyzed using Fisher's exact test.

The prevalence and incidence of end-stage renal disease in Taiwan ranks highest in the world, and it is based on the 2018 health welfare According to statistics from the Ministry of Foreign Affairs, kidney disease is the ninth leading cause of death in Taiwan. As the course of chronic kidney disease (CKD) progresses, autonomic nervous system dysfunction, inflammation, and physical and psychological symptoms (such as fatigue, sleep disturbance, and depression) will increase, which will further damage the structure and function of the kidney Intensified, increasing the demand for dialysis treatment and the risk of cardiovascular disease, which consumes social and medical costs. If the investigators can intervene in a feasible measure to effectively regulate the autonomic nervous function of CKD patients, reduce inflammation and physical and psychological symptoms, and delay the progression of the disease, it will be the main goal of caring for CKD patients. To explore the intervention of heart rate variability biofeedback, which can improve the autonomic nervous function (heart rate variability \[Heart Rate Variability\]), inflammatory response (interleukin-6 \[Interleukin-6, IL-6\], C-reactive protein \[ C reaction protein, CRP\]) and physical and psychological symptoms (such as reducing fatigue, sleep disturbance and depression).
NCT03674957
Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases. The objective of The Manitoba Personalized Lifestyle Research (TMPLR) study is to understand how these lifestyle factors interact with each other and additional factors, such as an individual's genetics and gut microbiome, to influence health. This is an exploratory cross-sectional observational cohort study of adults, with extensive phenotyping by objective health and lifestyle assessments, and retrospective assessment of early life experiences, with retrospective and prospective utilization of secondary data from administrative health records. A planned non-random convenience sample of 840 Manitobans aged 30-46 recruited from the general population, stratified by sex (equal males and females), body mass index (BMI; 60% of participants with a BMI \>25 kg/m2), and geography (25% from rural areas,). These stratifications were selected based on Manitoba demographics. Body composition and bone density will be measured by dual energy x-ray absorptiometry. Blood pressure, pulse wave velocity, and augmentation index will be measured on two consecutive days. Chronic disease risk biomarkers will be measured in blood and urine samples. DNA will be extracted for genetic analysis. A fecal sample will be collected for microbiome analysis.
