The Use of Risk Prediction to Identify Patients at Risk for Chronic Kidney Disease: Patient and Provider Interventions for Patients at High Risk for Chronic Kidney Disease

This prospective, cluster-randomized trial is structured as a pragmatic study, embedding the outreach intervention within routine clinical workflows. The intervention reflects real-world provider-patient communication methods. The primary research aim is to evaluate, under typical practice conditions, whether structured notification strategies improve follow-up screening. We will evaluate whether targeted provider and patient-directed communication increases completion of CKD disease lab testing (eGFR and uACR) among individuals identified as being at risk for having CKD based on the model developed in in Phase 1. We will identify up to 1,000 patients with high risk of having CKD. All patients' primary care providers (PCPs) will receive a message notifying them of patients' elevated risk status and the recommendation for CKD testing per standard practice. Additionally, we will randomly allocate providers whose patients will receive letters ( \~n=500 patients) and providers whose patients will receive a phone call ( \~n=250 patients).

Walnuts for Cardiorenal Protection in Adults With Chronic Kidney Disease

To date, no rigorous randomized controlled trials have demonstrated a protective effect of daily moderate walnut consumption on kidney function or chronic kidney disease (CKD) progression in individuals with CKD. Objective: To determine the effect of walnut supplementation (30 g/day of raw walnuts) within a Mediterranean diet (MedDiet) based dietary counseling program, compared with the same MedDiet counseling program without walnut supplementation, on kidney function, CKD progression and regression, and classical and emerging cardiovascular risk markers in individuals with CKD. Secondary objectives focus on assessing whether regular walnut consumption as a healthy snack has a positive impact on inflammation, oxidative stress, endothelial dysfunction, and intestinal dysbiosis, conditions intrinsically linked to CKD that play a pathophysiological role in promoting/exacerbating its progression and the development of comorbidities in this vulnerable group of subjects. Methodology: A 6-month randomized controlled trial will be conducted in 150 men and women aged 45 to 75 years with stable mild to moderate CKD (stage G3a-b), overweight or obesity, and high cardiometabolic risk. The study will compare the effect of two interventions assessed at 3 and 6 months on the following outcomes: 1. Primary outcomes: a) changes in kidney function assessed by the Estimated Glomerular Filtration Rate based on creatinine and cystatin C (eGFRcr-cys); b) CKD progression; and c) CKD remission 2. Secondary outcomes: a) urinary albumin-to-creatinine ratio (UACR); b) mineral and bone metabolism parameters, c) anthropometry and body composition (Dual-Energy X-ray Absorptiometry, DXA); d) bone mineral density (DXA); e) diet quality; f) physical activity; g) medication use; h) psychological well-being; i) quality of life; j) classic cardiovascular risk markers; k) iron status and hepatic function; l) inflammation, endothelial function, and oxidation markers; m) gut microbiota

Evaluation of the Risk of Heart Failure in Patients With Chronic Kidney Disease and Type 2 Diabetes Mellitus

The goal of this study, performed entirely with computer programs, is to learn if using a combination of two drugs works better than using one alone, in the treatment of people with chronic kidney disease and type 2 diabetes mellitus. The main questions it aims to answer are: * How many events of heart failure, heart failure hospitalizations, and cardiovascular death happen in each group? * How do serious kidney problems progress in each of the groups? Researchers will compare reference therapy (finerenone) with a combination of finerenone and empagliflozin. There will not be human participants in this study. With the help of artificial intelligence, researchers will recreate a large population of people with chronic kidney disease and type 2 diabetes mellitus. Data on their disease, treatment, and laboratory parameters will be based on and simulated using real data from previous clinical trials conducted with real participants.

Association Between Chronic Kidney Disease Stage and Circulating FGF23 Cleavage Intensity in Patients With Chronic Kidney Disease

This cross-sectional proof-of-concept study aims to investigate the relationship between chronic kidney disease (CKD) severity and circulating FGF23 (fibroblast growth factor 23) cleavage intensity estimated by the iFGF23/cFGF23 ratio. Eighty male patients aged 55-75 years with CKD stages 3a to 5 will be included (20 per stage). Blood samples obtained during routine nephrology care will be supplemented by two additional tubes to measure iFGF23, cFGF23, hepcidin, erythropoietin, 1,25-vitamin D and TRAP5b. The primary endpoint is the iFGF23/cFGF23 ratio. Secondary analyses will evaluate the associations between FGF23 forms and renal, hematological, iron metabolism and mineral bone parameters. This study will provide the first human data on FGF23 cleavage alterations across CKD stages and may identify novel biomarkers for anemia and cardiovascular complications.

Efficacy and Safety of Triple Therapy With Dulaglutide, SGLT2 Inhibitors, and Finerenone in Chinese Adults With Type 2 Diabetes and Chronic Kidney Disease

The purpose of this study is to evaluate whether adding dulaglutide to the combination therapy of Sodium-Glucose Co-Transporter 2 Inhibitors(SGLT2i) and finerenone can provide additional kidney protection and safety for Chinese adults with Type 2 Diabetes Mellitus(T2DM) and Chronic Kidney Disease(CKD). Eligible participants will be adults with T2DM and mild-to-moderate CKD who have been receiving SGLT2 inhibitor plus finerenone for at least 3 months on the basis of maximum tolerated dose of renin-angiotensin system inhibitor (RASi). Participants will be randomly assigned to either continue the original regimen or to receive add-on therapy with dulaglutide.The study will last for 26 weeks, with participants required to attend scheduled visits for efficacy and safety assessments at Week 13 (±1 week) and Week 26 (±1 week, final visit).

A Randomized Trial of Six-Channel RF Ablation System for Renal Denervation in Uncontrolled Hypertension and Chronic Kidney Disease

Prospective, Multi-Center, Randomized, Parallel-Controlled, Uptake clinical trial to evaluate the efficacy and safety of the six-channel radiofrequency（RF) renal denervation system-comprising the six-channel radiofrequency generator (specification model: 25D1G, software release version: SRG-V1) and the disposable ultra-guiding radiofrequency denervation catheter (specification model: 25C6W127F115T)-for renal denervation in patients with uncontrolled hypertension and chronic kidney disease.

The Effects of Dietary Nitrate in Patients With Hypertensive Kidney Injury

The study aims to study the effects of diatery nitrate in patients with hypertension and hypertensive kidney injury. The study is a randomized, placebo-controlled, double-blinded crossover trial. 14-20 patients with hypertension and CKD I-III will be randomized to receive either nitrate or placebo delivered in the form of beetroot juice. Effect variables will be measured before and after a 2 week treatment. After a washout period of 14 days, the subjects are crossed over to the opposite treatment. The study is terminated by measuring effect variables after the second treatment period.
