Safety and Efficacy of SC101 Via Perirenal Fat Injection for Resistant Hypertension in Patients With Moderate to Severe Chronic Kidney Disease

This is a single-center, open-label, exploratory clinical study designed to evaluate the safety and efficacy of a single-session injection of SC101, a small interfering RNA (siRNA) agent, into the perirenal fat. This study plans to enroll 3 participants, aged 18 to 65 years, who have a clinical diagnosis of resistant hypertension and moderate to severe chronic kidney disease (CKD).

Prospective AnalysiS of Self medIcation With phytOtherapy in Nephropatic Patients.

We propose the following hypotheses: * The use of herbal medicine is common among patients with chronic kidney disease in Réunion island. * This use could influence the progression of kidney disease in these patients. To assess the primary inclusion criterion, patients will be easily identified by nephrologists through existing follow-up. The questionnaires will be administered after this early identification by the investigators at each center. The primary evaluation criterion is straightforward: it aims to establish an overview of the use of herbal medicine in our patient population. This information is currently unavailable and remains crucial for measuring the extent of the issue. Our secondary criteria will involve more in-depth analysis of this use and an attempt to correlate the use of certain herbs with the rate of progression of kidney disease at one year. We targeted patients with moderate to end-stage chronic kidney disease (KDIGO classification 3 to 5), which are the stages typically included in kidney disease studies. Furthermore, these patients are the most likely to experience a greater annual progression of their kidney disease, and the effect of herbs on this progression could be investigated. Transplant patients were not included because they are more aware of the risks of not using herbal medicine due to their use of immunosuppressants.

Screening for Cardiac and Cardiac-associated Pathology Using Single-channel Electrocardiogram

It is a prospective, controlled, single-center, observational, non-randomized study. The study is planned to include at least 4000 patients 18 years old and older in the training sample and 1000 patients over 18 years old in the test sample (the total number of patients is at least 5000 people). Patients will be included in the study if they have undergone a full examination (laboratory, clinical and instrumental), allowing for the verification or exclusion of cardiac and cardiac-associated pathology in accordance with current recommendations. During the course of the study, the authors of the work do not interfere with the above-mentioned scope of the examination, which is carried out on patients in accordance with clinical guidelines. All patients included in the study will undergo ECG recording in standard lead I for 1 minute twice, followed by spectral analysis of the obtained data, which will be stored at the remote monitoring center of Sechenov University without being linked to the personal data of patients. A spectral analysis of the electrocardiogram will be performed using a continuous wavelet transform. The result of this study will be the identification of ECG parameters that will correlate with cardiac and cardiac-associated pathology

Phosphate Assessment in Chronic Kidney Disease Patients Study

The proposed pilot feeding study aims to explore novel pathways in phosphate metabolism and identify new biomarkers, as well as to develop a compound index for assessing phosphate overload with high validity and reliability. Investigators will address the following specific aims: 1). To explore novel pathways of phosphate metabolism and assess the influence of CKD status on these metabolic pathways. 2). To identify novel biomarkers for phosphate overload that reflect changes in dietary phosphorus intake. 3). To develop a compound phosphate overload index that measures dietary phosphorus intake with high validity and reliability. This study will provide novel insights into phosphate metabolism and the assessment of phosphate overload in CKD patients. This investigation aims to provide preliminary data to further studies for the development of reliable biomarkers in CKD patients, which could contribute significantly to early interventions and improve health outcomes.

AK+ Guard™ Pilot Study in Chronic Kidney Disease: Outpatient Diagnostic Accuracy and Remote Monitoring

The goal of this observational pilot study is to evaluate the investigational AK+ Guard™ software as a medical device (SaMD) for detection of moderate to severe hyperkalemia (serum potassium (K+) ≥ 6.5 mmol/L) in adults with chronic kidney disease (CKD). Study objectives are: * Arm 2A (Outpatient Diagnostic Accuracy): To generate a preliminary, real-world signal of the diagnostic performance of AK+ Guard™ when used in an ambulatory CKD cohort for identifying clinically significant hyperkalemia episodes (serum K+ ≥ 6.5 mmol/L) at the time of an outpatient laboratory draw. * Arm 2B (Remote Patient Monitoring): To assess participant compliance, usability, and end-to-end system reliability of AK+ Guard™ when deployed for daily remote monitoring of CKD patients outside the clinical environment for up to four weeks.

Equol and Vascular Function in Women With Chronic Kidney Disease

The risk of cardiovascular disease (CVD) is significantly elevated in patients with chronic kidney disease (CKD). Notably, women with CKD commonly experience menstrual disturbances induced by CKD, which may contribute to impaired vascular function and elevated CVD risk. However, most of the literature in nephrology focuses on male patients, and studies on women's vascular health are limited. Establishing effective therapies for improving vascular function and reducing CVD risk in women with CKD is a high research priority of the NIH. Equol contributes to improvement in vascular function, mediated in part by its anti-oxidative and anti-inflammatory properties. However, there is no information on the effect of equol on vascular function in women with CKD. The proposed project aims to determine the effect of 12 weeks of oral equol supplementation on vascular function in postmenopausal women with CKD.

ACE Reno, Pico Cell Matrix and Its Effect on eGFR in Chronic Kidney Diseases

This study investigates the safety and efficacy of ACE Reno, an oral transmucosal solution containing standardized bioactive peptides and amino acids, in patients with nephropathy of various etiologies and stages. The trial evaluates whether 12 weeks of ACE Reno (1 mL sublingually four times daily) reduces albuminuria/proteinuria and stabilizes kidney function in participants with nephropathy due to diabetes, hypertension, autoimmune disease, reflux/UTI, chronic glomerulonephritis, unknown etiology, pre-dialysis CKD, or post-transplant proteinuria. Nephropathy remains a global health burden, with \~9-10% of the population affected by chronic kidney disease (CKD), equating to \>750 million individuals worldwide. The socioeconomic costs are substantial: in England CKD costs \~£7 billion annually, projected to rise to \~£14 billion by 2033; in Malaysia, prevalence rose from 9% to 15.5% within 7 years; in Egypt, CKD imposes heavy familial and financial burdens, especially for pediatric patients; in Turkey, CKD is among the top causes of disability, linked to the rising tide of diabetes, obesity, and hypertension. ACE Reno is designed to address multiple drivers of CKD progression - glomerulosclerosis, fibrosis, endothelial dysfunction, and maladaptive RAAS/aldosterone signaling - through its peptide components that mimic antifibrotic (BMP-7, HGF, Klotho-like) and vasodilatory/cGMP-mediated (natriuretic peptide-like) pathways.
