FAP-targeting PET/CT for Noninvasive Monitoring of Renal Fibrosis
Chronic kidney disease (CKD) is an irreversible change of kidney function and structure caused by many reasons. The main threat of CKD to human health is progressive renal function decline. Delaying the progression of chronic kidney disease to end-stage renal failure is an important clinical need, and renal fibrosis is a common pathway for the progression of chronic kidney disease to end-stage renal failure. The evaluation of renal fibrosis is of great value for the course and prognosis of patients with chronic kidney disease. However, pathological detection has the disadvantages of trauma, false negative, and cannot be implemented repeatedly. At present, there is a lack of effective non-invasive, dynamic, real-time monitoring and evaluation means. A commercially available FAP-targeted imaging agent, FAPI-04, has been used for PET/CT imaging of systemic fibrosis lesions with high uptake background in normal kidneys. Although it can show severe renal fibrosis, it is not conducive to the detection rate of patients with mild-moderate fibrosis who need more accurate evaluation. The new targeted FAP imaging agent successfully constructed by our research group has proved that it can show the degree of renal fibrosis at the living level and has correlation. Therefore, this study intends to carry out a series of clinical studies on the imaging of renal fibrosis with new targeted FAP probes, evaluate the specificity and sensitivity of the new targeted FAP probes in the diagnosis of renal fibrosis, and ultimately provide a new method for clinical dynamic, non-invasive assessment and monitoring of the degree and progression of renal fibrosis.

Comparative Study on the Mode of Action of Vicadrostat and Spironolactone on Protein Profiles and Renal Hemodynamic Effects (COMPARE-VS)
In this study, investigators will compare the effect of vicadrostat combined with empagliflozin with the effect of spironolactone combined with empagliflozin on renal function and changes in protein profiles in blood and urine. The hypothesis is that the renal and cardiac responses between vicadrostat and spironolactone differ due to mechanistic differences in their mode of action. Spironolactone is a mineralocorticoid receptor antagonist (MRA) and exerts its effect on a receptor, or a type of "receiver," found on various cells. Vicadrostat is an aldosterone synthase inhibitor (ASI) and inhibits aldosterone production. Therefore, both drugs affect aldosterone. However, studies evaluating the differences between MRAs (such as spironolactone) and ASI (such as vicadrostat) and examining their effects on the kidneys in patients with chronic kidney disease with concurrent cardiovascular disease, and/or heart failure are still lacking. For this study, all participants will be divided into two groups: * Group 1. Participants in this group will receive one tablet of vicadrostat (10 mg) and one tablet of empagliflozin (10 mg) daily for 26 weeks. * Group 2. Participants in this group will receive one tablet of spironolactone (25 mg) and one tablet of empagliflozin (10 mg) daily for the first four weeks. Participants in this group will then receive two tablets of spironolactone (50 mg) and one tablet of empagliflozin (10 mg) daily for the remaining 22 weeks. The spironolactone dosage may be adjusted during the study period (from 12.5 to 50 mg) based on blood test results.

Hyperlipoproteinemia A as a Marker of Cardiovascular Risk in Patients With Stage 4 Chronic Kidney Disease
The blood level of lipoprotein A (Lp(a)) is linked to mutations in gene 6 and is associated with atherothrombotic risk and clinical manifestations such as myocardial infarction, ischemic stroke, and aortic valve calcification and stenosis. Several studies show an increased cardiovascular risk for a level \>125 nmol/L. Patients with severe chronic kidney disease (CKD) or on hemodialysis are at high cardiovascular risk, and Lp(a) levels would allow for better reclassification of this cardiovascular risk in the general population. The study authors wished to the heterogeneity of the Lp(a) level in the population with CKD stages 4 without renal replacement therapy and to identify whether a high Lp(a) level is associated with cardiovascular comorbidity defined by the presence of cardiovascular comorbidity after adjustment for known risk factors such as diabetic status, obesity, smoking, LDLc level and medical treatment for cardiovascular prevention (statins, etc.). Furthermore, they will evaluate whether there is a link between a high level (\> 125 mmol/l) of Lp(a) at inclusion in the cohort and the occurrence of cardiovascular or renal events (i.e. death of cardiovascular origin or occurrence of MI, stroke, stage 4 peripheral artery disease (PAD) or initiation of renal replacement) over a follow-up period of 18 months which could raise questions about the benefit of a specific treatment which remains to be evaluated.

The Effect and Mechanism of Xiqing Regulating Intestinal Homeostasis on Drug Efficacy of Chronic Kidney Disease
Chronic kidney disease (CKD) has become a major public health problem worldwide. Patients with CKD are often accompanied by azotemia due to impaired renal function and excretion of nitrogen metabolic waste, which leads to multiple organ dysfunction, cardiac dysfunction and other complications. Therefore, it is an important strategy in the treatment of CKD to reduce the burden of kidney in CKD patients by removing nitrogen metabolic wastes in the body. Xiqing, which includes coated aldehyde oxystarch capsules, is a drug with adsorption effect. As an effective nitrogen metabolic waste adsorbent, it is widely used in the treatment of CKD patients. Gut is an important organ for the generation of nitrogen metabolic waste in the body. Intestinal homeostasis is an important regulator of nitrogen metabolism, and supplementation of probiotics is one of the main ways to regulate intestinal homeostasis. A study published by the team of investigators in the journal Cell Metabolism in 2021 confirmed that probiotics (Lactobacillus casei Zhang) reduced the BUN level in CKD mice, intestinal inflammation and the permeability of intestinal mucosal barrier, and delay the progression of CKD patients through animal experiments and clinical trials. So, whether the application of Xiqing changes intestinal homeostasis, including intestinal flora structure, function and function of intestinal mucosa, intestinal metabolites? Whether drug effect is affected by intestinal balance of CKD? What is the mechanism? Is Xiqing combined with probiotics more conducive to reducing BUN level and delaying the progression of CKD patients? The discussion of the problem and solution will help clinicians for the pioneering understanding of the use of Xiqing. In this study, the investigators designed a prospective, randomized, open-label, blinded end-point clinical trial, using microbial diversity, metagenomics, targeted and non-targeted metabolomics detection and other technologies, through the joint analysis of multi-omics data, to explore the effect of the use of Xiqing on the intestinal homeostasis of CKD, and the extent of the drug efficacy of Xiqing is affected by the intestinal homeostasis of CKD. The effect of Xiqing combined the probiotics regulating intestinal homeostasis on CKD and the molecular mechanism, which provide more research references for the clinical application of Xiqing.

Explorative Study to Investigate the Acid-base Response to Sodium and Potassium Salts in Patients With Chronic Kidney Disease.
With this research the investigators want to study how patients with chronic kidney disease respond to different sodium- and potassium salts. Potassium salts can prevent kidney damage and cardiovascular disease, however patients with chronic kidney disease can responds differently. Extra potassium can increase the amount of potassium in the blood and extra chloride can cause acidosis. With this study the investigators will gain more insight in how patients with chronic kidney disease respond to sodium and potassium salts and which one is more favorable.This information can then be used to guide the application of salt substitutes and dietary adjustments in patients with chronic kidney disease.

A Cluster Randomised Controlled Trial of a Multimodal Integrated Intervention for Kidney Cachexia
This lay description has been written in conjunction with, and the content approved by our Patient and Public Involvement collaborators. Patients with kidney cachexia will experience extreme muscle loss, reduced strength and symptoms including fatigue, reduced appetite and lower quality of life. Patients are also at an increased risk of hospitalisation and shortened life expectancy. Previous research suggests that treatments that target several causes of the muscle wasting syndrome (known as cachexia), show better outcomes for patients than treatments using just one method (for example only exercise). We want to see if combining different treatments (exercise, dietary advice and anti-inflammatory supplements) will improve outcomes for patients with kidney failure receiving haemodialysis at risk of developing kidney cachexia, compared to patients who only receive routine kidney care alone. However, there is currently no routine treatment for kidney cachexia. Individual treatments, such as exercise, have not been successful to slow the progression of wasting in chronic diseases. Our recent review of scientific literature highlighted dual treatments of exercise and dietary advice is effective to varying degrees. Combined treatments which include anti-inflammatory supplements (including those found in fish oils), alongside exercise and dietary advice, have been successfully trialled in other chronic illnesses, such as cancer for the treatment of cachexia. However, this bundle of three treatments has not been tested in patients with kidney cachexia. It is important to test whether such a combination of treatments will be practical for patients and clinicians. Our study will assess how well this intervention works in the healthcare system and if it shows potential to help patients with kidney cachexia. Patients at risk of kidney cachexia who are receiving haemodialysis at two renal departments have been assigned to the treatment group (Multi-Modal Integrated intervention combining Exercise, Anti-inflammatory \& Dietary advice plus routine care) and two have been assigned to the control group (routine care). Over 12 weeks, those in the treatment group will receive an individualised exercise programme, dietary advice and anti-inflammatory (fish oil) nutritional supplements. We will collect data on how successful the trial is (e.g., how many patients took part, completed all components of the study). Additionally, we will collect data on physical functioning, muscle mass, body weight, quality of life and survival. After 12 weeks, we will interview patients and clinicians to evaluate, if any, changes can be made to improve the intervention within what is called a 'process evaluation'.

Study of Oral Uremic Toxin Absorbent and Probiotics to Retard the Progression of Chronic Kidney Disease
In patients with chronic kidney disease (CKD), uremic toxins accumulate when kidney function declines. Those uremic toxins had a greater affinity to circulating proteins are called "protein bound uremic toxins, PBUT." Apart from traditional small or middle molecule uremic toxins, the PBUTs can be rarely eliminated using traditional renal replacement therapy, even using high flux dialysis modalities. Among these molecules identified, indoxyl sulfate (IS), and p-cresol (PC) are mostly studied. Both in vitro and in vivo study, IS and PC are associated with endothelial dysfunction, vascular smooth muscle proliferation, and increased risk for CV outcomes. The uremic toxins (IS and PC) are originated in the endogenous environment, mainly from the protein metabolism, food intake, or produced by gut microbiota. Prevention of IS or PC precursors from being absorbed across the intestinal tract has been extensively studied in the renal literature by use of oral adsorbents. In animal models, activated charcoal reduces the serum concentration of creatinine (cre) and may delay CKD progression by alleviating IS overload. An oral form of non-absorbable surface-modified activated bamboo charcoal (ABC), has been demonstrated to effectively reduce circulating and renal IS levels in animal models. Recently, probiotics, prebiotics or synbiotics have been reported to reduce inflammation, improve kidney function and retard progression of CKD by restoring the symbiosis of gut microflora in patients with CKD. A randomized trial found synbiotics decreased serum PCS without reducing serum IS in non-dialysis CKD. Another study found that synbiotics delayed CKD progression. A systematic review found prebiotic and probiotic therapies reduced IS and PCS in patients with end stage kidney disease (ESKD) on haemodialysis. However, it is unclear whether the results hold true for other patients with CKD. Based on these previous findings, investigators will conduct a prospective randomized open blinded end-point (PROBE) study to see if oral uremic toxin absorbent + probiotics prevent CKD progression. Also, a panel of clinical and biochemical profiles will be checked to investigate possible link between several biomarkers and clinical response.

Oral Absorbent and Probiotics in CKD Patients With PAD on Gut Microbiota, IncRNA, Metabolome, and Vascular Function
Taiwan has more chronic kidney disease (CKD) per capita than anywhere in the world, leading to the highest expense of National Health Insurance. By reviewing previous studies, uremic toxins contribute critically to the detrimental effects of CKD on atherosclerotic peripheral artery disease (PAD). When recognized early and managed appropriately, mortality and complications of the participants with CKD and established PAD can be minimized. It is critical to identify novel biomarkers and mediators, which can help identify those with potential poor outcomes and facilitate the discovery/development of novel therapeutics for the patients with CKD and PAD. The OMICs studies support the theory that gut microbiome is a major contributor to adverse cardiovascular outcomes and progression of CKD. However, successful integration of multi-omics approach remains sparse. There is no report on the impact of gut microbiota on the host circulating long non-coding RNAs (lncRNAs) expression signature, other CAD/PAD potential marker, and the potential link between gut microbiota, circulating lncRNA levels changes and CKD/PAD. Additionally, although numerous studies indicated that probiotics or activated charcoal have benefits for CKD patients, few studies evaluated the effect of coadministration of activated charcoal/probiotics on the patients with CKD/PAD. The mechanisms of therapeutic effect on CKD/PAD patients with coadministration of activated charcoal/probiotics involving the cross talk among host, microbiota and metabolites still remain unclear. Thus, in the present study, investigators aim to develop novel diagnostic/prognostic markers and a new treatment with activated bamboo charcoal (ABC)/probiotics for therapeutic opportunities to prevent cardiovascular complications, amputation and death in CKD patients with established PAD. To identify the diagnostic/prognostic markers, the multi-omics (microbolome and metabolome) and lncRNA will be analyzed. The therapeutic impact of activated bamboo charcoal (ABC)/probiotics with optimal formulation, on the renal/endothelial/vascular function, cardiovascular (CV) outcome and mortality in CKD patients with PAD will be also determined to evaluate its therapeutic opportunities.

lncRNAs as a Biomarker to Assess the Therapeutic Impact of Oral Absorbent ± Probiotics in CKD Patients With PAD
Participants with chronic kidney disease (CKD) are at a higher risk of developing atherosclerotic peripheral artery disease (PAD). Retention of uremic toxins such as indoxyl sulfate (IS), p-cresyl sulfate (PCS) and trimethylamine N-oxide (TMAO) during CKD is detrimental to endothelial and vascular function and can predispose to the development and progression of PAD. Many of the uremic toxins originate from gut microbial metabolism. Removal of these uremic toxins by carbonaceous oral adsorbent is beneficial, slowing down the deterioration of renal function and delaying the need for dialysis in CKD patients. However, if carbonaceous oral adsorbent could also improve vascular function and clinical outcomes in CKD patients with established PAD, remains unknown. In this proposal, the investigators aim to determine the therapeutic impact of a carbonaceous oral adsorbent made of activated bamboo charcoal (ABC) with/without probiotics on the endothelial/vascular function, CV outcome and mortality in CKD patients with PAD. In addition, the investigators hypothesize that circulating long noncoding RNA (lncRNA) expression profiles and metabolome may serve as a sensitive and reliable biomarker to predict the adverse CV outcomes and death in CKD patients with established PAD. In addition, it is hypothesized that circulating lncRNAs and linked to adverse CV outcomes in CKD patients with PAD are associated with dysbiosis of gut microbiota. The investigators also hypothesize that the administration of ABC could normalize the dysbiosis of gut microbiota, dysregulated circulating lncRNAs and metabolome that are linked to adverse CV/limb outcomes in CKD patients with PAD. This will be a prospective, randomized, open-labeled, blinded end-point trial for 6 months, followed by integrated assessment of endothelial/vascular function, changes in conventional athero- and inflammation-relevant biomarkers, circulating long noncoding RNAs, metabolome, and gut microbiota at baseline, ends of the 3rd and 6th month, as well as clinical CV, renal and limb outcomes up to 3 years.

FGF23 and Cardiovascular Damage in Anemia With an Without Chronic Kidney Disease.
Anemia is associated with cardiovascular disease. Iron deficiency is usually induced in chronic kidney disease (CKD). In clinical studies, an inverse association between serum levels of iron and fibroblast growth factor 23 (FGF23), a cardiovascular risk factor, has been demonstrated. In addition, a number of the I.V. iron presentations mostly used to treat anemia show unwanted side effects related to phosphate alterations and increased FGF23. Objectives. The General Objective of this project is to evaluate, through in vivo and in vitro studies, the cardiovascular alterations related to the anemia-induced increase in FGF23 production; as well as the identification of possible molecular targets that may be useful in its prevention and/or palliation. Specific Objectives are: 1) To determine in a population with anemia (due to iron deficiency), with and without CKD, an association between the parameters related to iron metabolism, FGF23 and markers of cardiovascular damage. 2) To evaluate in vivo, in a murine experimental model of anemia, with and without CKD, the effects of the modulation (inhibition) of triggers of iron deficiency (hepcidin) and of the increase in FGF23 (HF1α), on markers of cardiovascular damage. 3) To compare in vivo, in an experimental model of anemia with and without CKD, the effect of different I.V. iron presentations (ferrous sulphate, ferric carboxymaltose and ferric citrate) on FGF23 levels and their cardiovascular impact. 4) To evaluate in vitro, in cardiomyocytes cultures, in the presence of iron deficiency, the direct effect of FGF23 on the induction of cardiac damage. 5) To evaluate in vitro, in osteoblasts cultures, the direct effect of ferrous sulphate, ferric carboxymaltose, ferric citrate and hepcidin. Methodology. The levels of intact and C-terminal FGF23 (FGF23i and FGF23c), the differential expression profile of plasma miRNAS and of proteomic, markers of cardiovascular disease, mineral metabolism, inflammation and oxidative stress and intracellular signalling pathways will be evaluated.
