Quality of life should be assessed and managed in all dialysis patients. Lowering the temperature of the dialysis bath in the MyTemp trial does not appear to have an effect on mortality and cardiovascular events. High volume convective hemodiafiltration currently represents the reference technique in hemodialysis; the Convince study confirms its superiority in terms of all-cause mortality. The DIATT study shows the benefit of the presence of an adapted physical activity professional to promote physical activity in dialysis patients and shows that it is necessary for this support to be reimbursed. The RENAL-AF and AXADIA-AFNET 8 studies lack power to conclude on the use of new oral anticoagulants in hemodialysis. For angiotensin receptor neprilysin inhibitors, studies are too weak to allow their use. SGLT2 inhibitors could be used in peritoneal dialysis to increase diuresis or delay the appearance of peritoneal fibrosis but to date only studies on models animals exist. Factor XI inhibitors are a new therapeutic class that could be used and would reduce the risk of thrombosis and hemorrhage. Increasingly, the feelings of patients and caregivers are more and more taken into account. Patient/caregiver communication must be at the heart of care.

These cognitive disorders occur early during the course of the kidney disease and evolve in parallel with the decline in glomerular filtration rate. They affect 30 to 80 % of patients with stage 5 CKD. Kidney transplantation only partially improves cognitive impairment. In this narrative review, we summarize the epidemiology and recent clinical and experimental data on cognitive impairment in CKD and discuss the potential specific mechanisms. Among the factors associated with cognitive impairment, the accumulation of uremic toxins such as indoxyl sulfate appears to be a specific risk factor for cognitive decline. These toxins have an endothelial toxicity that can disrupt the cerebral endothelium. The rupture of the blood-brain barrier (BBB) is a mechanism implicated in several neurodegenerative pathologies and systemic diseases with cerebral tropism. Recent experimental findings in CKD indicate that disruption of the BBB appears to be an important mechanism behind cognitive impairment in CKD. In murine models of CKD, increased BBB permeability is linked to memory impairment and aryl hydrocarbon receptor activation following accumulation of circulating indoxyl sulfate. This disruption of the BBB could also have harmful consequences for stroke susceptibility and drug neurotoxicity in CKD patients.</p>","PeriodicalId":94153,"journal":{"name":"Nephrologie & therapeutique","volume":"19 7","pages":"607-615"},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138500569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
