Chronic Kidney Disease Stage 3

The goal of this crossover clinical trial is to explore the effects of red meat intake on serum and fractional urinary excretion of uremic toxins including trimethylamine N-oxide in people with chronic kidney disease.

The study will leverage the established multi-stage cohort resources at Huashan Hospital, covering the entire spectrum from early-stage CKD to dialysis, including a comorbidity real-world database, a prospective CKD patient cohort, and a maintenance hemodialysis patient real-world cohort. It will also collaborate with the Shanghai Fifth People's Hospital (community-based CKD cohort, n\>2,000) and the Jing'an District Central Hospital (end-stage renal disease cohort, n\>400) as external validation platforms. Using epidemiological and big data-driven approaches, the study aims to elucidate the mechanisms underlying disease progression and complications, construct intelligent intervention models, and validate their performance in the external cohorts, ultimately facilitating the optimization and broader application of comprehensive CKD management strategies.

The overall objective of this pilot randomized clinical trial is to determine whether low-dose Colchicine (LoDoCo) improves vascular disease including vascular calcification, peripheral arterial disease (PAD), and chronic kidney disease-mineral and bone disorder (CKD-MBD) biomarkers in patients with chronic kidney disease (CKD) stage 3 over a 12-month intervention period, compared with usual care. Successful completion of this study will generate critical preliminary data to support a larger clinical trial aimed at evaluating inflammation-targeted therapies to mitigate CKD-MBD, including vascular calcification and related PAD, as well as osteoporosis, ultimately reducing cardiovascular events and mortality in patients with CKD. Additionally, this work has the potential to redefine the diagnostic framework for CKD-MBD.

The goal of this clinical trial is to learn about the safety (good or bad) of giving two AION-301 intravenous (IV) infusions, in adults with Stage 3 Chronic Kidney Disease (CKD). It will also help to learn if AION-301 reduces the symptoms of CKD and/or progression. The main questions it aims to answer are: * Do participants have medical problems (adverse events) after receiving two infusions of AION-301? * Do participants feel better (have reduced and/or delayed CKD symptoms)? * To learn about how AION-301 works in participants with CKD? Researchers will compare AION-301 to a placebo (a look-alike substance that contains no drug) to see if AION-301 works to treat Stage 3 CKD. Participants will: * Receive two infusions of AION-301 or placebo on two separate days (Day 0 and Day 4). * Receive oral vitamins at the clinic and to take at home for 90 days. * Visit the clinic for a minimum of 9 times, over 6 months for checkups and tests, but could be up to 12 times, over 24 months for checkups and tests.

The main objective of this study is to evaluate the effect of fully automated closed-loop glucose control on renal tissue oxygenation among people with type 2 diabetes and chronic kidney disease. This is a single-center, open-label parallel design study that will compare 26 weeks of fully-automated closed-loop glucose control with standard insulin therapy and continuous glucose monitoring, following a run-in period. A total of up to 76 adults with type 2 diabetes and chronic kidney disease will be recruited through outpatient diabetes and nephrology clinics. The primary outcome is renal tissue oxygenation measured using blood oxygenation level-dependent magnetic resonance imaging at 26 weeks. Other key outcomes include glycated hemoglobin at 26 weeks and time spent with glucose levels within and above the target glucose range (3.9-10.0mmol/L). Other glycemic and renal outcomes (including renal function) will also be assessed, as well as patient-reported outcome measures using validated questionnaires. Safety evaluations include severe hypoglycemic episodes and other adverse and serious adverse events.

Currently used tests for chronic kidney injury only assess the function of one part of the kidney: the filter called the glomerulus. The other part, called the tubule, is disregarded. Based on many previous studies, the investigators have good reason to assume that a better prediction of the course of chronic kidney disease by testing tubular function will be possible. This is important, for example, when patients need to be treated with kidney-protecting drugs.

This study is a 6-month, pragmatic, multi-center, sequentially recruited, stratified, open-label randomized controlled trial (RCT) conducted in Malaysia. It aims to determine the clinical effectiveness of a culturally adapted, gamified mobile health app (MyNutriKidney®) supplementing standard care, compared to standard care alone, for improving dietary self-management among 200 adults with Chronic Kidney Disease (CKD) stages 3-5. Participants will be randomly assigned (1:1, stratified by age and education) into either (i) the intervention group (MyNutriKidney® app + standard care) or (ii) the control group (standard care, including routine dietary counseling and printed materials). The co-primary outcomes are changes in Dietary Adherence (measured by CKD Diet Score) and Nutrition Literacy (measured by NLS score) from baseline to 6 months.
