As kidney function declines, the prevalence of CVD, cardiovascular events, and mortality increases. This review considers recent evidence for the association between physical activity (PA) and exercise and cardiorenal health, and the effectiveness of interventions for the prevention and management of cardiorenal decline across the CKD spectrum. Evidence supports a beneficial dose-response effect of PA in the prevention of incident CKD, and growing evidence in prevalent CKD patients for the attenuation of kidney function decline, and a reduction in CVD risk, morbidity, and mortality. Broadly speaking, across the trajectory of CKD, the literature supports the efficacy of exercise interventions for improving cardiorespiratory fitness and aspects of cardiorenal health. The mechanisms underlying improvements indicate differential effects on traditional and non-traditional risk factors for CKD progression and CVD. To date, there is limited transfer of these findings into clinical care, although the evaluation of available evidence has led to the development of the first detailed clinical practice guideline for exercise and lifestyle in CKD. There is a lack of large-scale multi-centre randomised controlled trials, and trials exploring hard clinical outcomes and long-term effects of exercise on cardiorenal outcomes. However, research should also address the challenges of implementing programmes of exercise and PA as part of routine care in combination with addressing the shortfall in literature to improve cardiorenal outcomes in all patients with CKD.</p>","PeriodicalId":19078,"journal":{"name":"Nephrology Dialysis Transplantation","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142605452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of them is the maintenance of sufficient oxygen supply to the organs. For this purpose, the kidneys control the formation of red blood cells by the production of the hormone erythropoietin. This control of red cell formation is not only relevant to prevent states of oxygen deficiency but also to prevent an unwanted increase of red cell numbers causing thromboembolic risks. The adequate production of erythropoietin requires a sensing of the arterial oxygen content and transduction to hormone production. This oxygen sensing is a two-step process which includes a translation of the arterial oxygen content to respective oxygen tension in the tubulointerstitium and a perception of the resulting local interstitial oxygen tension to translate them into specific cellular responses such as the production of erythropoietin. This contribution will describe these steps of oxygen sensing for the healthy kidney and for the changes occurring during states of chronic renal disease, which are commonly associated with anemia. In this context a special focus will also be set on intrarenal hypoxia and oxygen sensing in the diabetic kidney including the treatment with tubular glucose transport (SGLT-2) inhibitors which might influence the oxygen sensing in the kidney. Finally, we will consider the effects of prolylhydroxylase inhibitors (PHD-I), which fundamentally interfere with the cellular oxygen sensing and which are meanwhile treatment options in renal anemia.</p>","PeriodicalId":19078,"journal":{"name":"Nephrology Dialysis Transplantation","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142576549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronic kidney disease (CKD) is set to become the fifth largest cause of death by 2040, with major impacts on low-resource countries. This review is based on a recent report of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) which uncovered gaps in key vehicles of kidney care delivery assessed using World Health Organization building blocks for health systems (financing, services delivery, workforce, access to essential medicines, health information systems and leadership/governance). High-income countries had more centres for kidney replacement therapies (KRT), higher KRT access, higher allocation of public funds to KRT, larger workforces, more health information systems, and higher government recognition of CKD and KRT as health priorities than low-income nations.

The results provide opportunities for kidney health policymakers, nephrology leaders and organizations to initiate consultations to identify strategies for improving care delivery and access in equitable, resource-sensitive manners. Policies to increase use of public funding for kidney care, lower the cost of KRT and increase workforces should be a high priority in low-resource nations, while strategies that expand access to kidney care and maintain current status of care should be prioritized in high-income countries.
