NCT07555327
This observational study documents the impact of a specific oral protocol (based on FDA-GRAS ingredients) on patients with Stage 5 Chronic Kidney Disease (CKD). The study observes 8 participants, including 6 with residual renal function and 2 patients with long-term total renal arrest (16 years and 22 years of anuria). The primary focus is monitoring the restoration of urine output and changes in renal biological markers.

End-stage renal disease is associated with hyperphosphatemia due to a decrease of renal phosphate excretion. This hyperphosphatemia is associated with an increase of cardiovascular risk and mortality. Thus, three therapeutic options have been developed: dietary restriction, administration of phosphate binders and phosphorus clearance by hemodialysis (HD). During a standard HD session, around 600 to 700mg phosphate is removed from the plasma, whereas it contains only 90 mg inorganic phosphate (Pi); 85% of phosphate is stored in bones and teeth in hydroxyapatite form, 14% is stored in the intracellular space (90% organic phosphate and 10% Pi), and 1% remains in the extracellular space. Currently, the source of Pi cleared during HD remains to be determined. Phosphorus (31P) magnetic resonance spectroscopy allows reliable, dynamic and non-invasive measurements of phosphate intracellular concentration. The investigator's team recently published data obtained in anephric pigs, suggesting that phosphate intracellular concentration increases during a HD session. In parallel, we showed that ATP intracellular concentration decreased. These results suggest that the source of Pi cleared during HD could be located inside the cell. In this study, investigators will measure intracellular phosphate and ATP concentrations and intracellular potential of hydrogen (pH) evolution during hemodialysis in 12 patients suffering from end-stage renal disease by MR spectroscopy. If these results were confirmed in humans, it could explain, at least in part, HD intolerance in some patients and would lead to modify therapeutic approaches of hyperphosphatemia, for example, by modifying HD sessions time.

The primary objective of the study is to evaluate the pharmacokinetics (PK) of avacopan and metabolite (M1) after a single dose of avacopan in participants with normal renal function and participants with ESRD requiring hemodialysis (HD).
NCT05649657
To assess the efficacy of a 6-month lifestyle intervention in patients with end-stage renal disease(ESRD), we plan to conduct a self-controlled clinical trial. 34 participants receiving chronic HD will be enrolled. Each participant will go through three phases: 3-month control, 6-month intervention, and 3-month maintenance. No intervention will be performed in the control and maintenance phases. The lifestyle intervention will comprise care from a multidisciplinary team, including a nephrologist, nurse practitioner, physiatrist, and dietitian. The exercise training component is an in-hospital supervised training 2\~3 times weekly for 6 months. Cyclic aerobic and resistance training will be performed. Assessment will be performed every three months and 5 times in total, including cardiopulmonary exercise testing, isokinetic quadriceps strength testing, hand grip strength, body composition analysis, Chinese Kidney Disease and Quality of Life questionnaire, self-recorded physical activity, and Mini Nutritional Assessment. The aim of this study is to assess the efficacy of a lifestyle intervention in patients with chronic kidney disease (CKD) on physical fitness, quality of life, and immunity. It is hypothesized that the lifestyle intervention will elicit a significant benefit in the aforementioned parameters and will last until the maintenance phase.
NCT01526798
Chronic inflammation in dialysis patients is linked to cardiovascular mortality and clinical signs and symptoms, like the impaired response to erythropoiesis-stimulating agents (ESAs). This study aims to demonstrate that high cut-off hemodialysis is effective in reducing chronic inflammation and thereby improving response to ESAs.
NCT00243958
Hearing impairment either clinical or subclinical is a characteristic of some renal disease patients. The hearing impairment could be result from specific etiologies or chronic renal failure itself. The causes of hearing impairment in renal disease patients ranged from drugs intoxication in both auditory and renal function, like gentamycin or isoniazid, congenital disease like Alport syndrome or other collagen-defective renal disease, or just aging related. End-stage renal disease (ESRD) patients are special in many parts to general population who have hearing impairment. First, inflammation in ESRD patients is well-documented, second, they suffered from various underlying diseases which auditory function was potentially impaired, third, they need to undergo renal replacement therapy either hemodialysis (HD) or peritoneal dialysis (PD) to maintain their life. Dialysis itself was found to be a cause of hearing impairment, too. The biochemical change and constitutive inflammation status are thought to be implicated in the pathogenesis of hearing impairment in ESRD patients. Aluminum (Al) is a well-documented heavy metal, which predisposes to Alzheimer's disease, dementia or some neurologic diseases. Al intoxication is very rare in general health population but elevated serum Al level is easily found in ESRD patients since they can not excrete Al by damaged kidneys and dialyzers. Inner ear per se is a neurologic tissue, so if serum Al level in ESRD patients has any association in their haring function needs to be studied.
