Epigenetic mechanisms and microRNA pathways further modulate APOL1 expression, influencing disease penetrance. Multiple models have clarified how subcellular localization, signal peptide processing, and interactions with the endoplasmic reticulum may contribute to pathogenesis. Therapeutic advances include inhibitors targeting APOL1 ion channel activity and strategies that block key inflammatory signaling pathways.Summary: These findings highlight a multifaceted disease process driven by both the intrinsic toxic potential of APOL1 variants and numerous extrinsic triggers. Understanding this complex interplay will be pivotal for risk stratification and the development of precision therapies, potentially improving outcomes for populations disproportionately affected by APOL1-associated kidney disease.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review summarizes the evidence supporting the benefits of these therapies on cardiorenal outcomes.Recent findings: Clinical trials have consistently demonstrated reductions in major adverse cardiovascular events with GLP1RA treatments. Recently, the FLOW trial revealed that semaglutide reduced the composite outcome of kidney failure, at least 50% decline in estimated glomerular filtration rate, kidney or cardiovascular mortality by 24% in patients with T2DM, thereby establishing GLP1RA as a pillar of therapy in this population. New evidence suggests favorable effects on kidney endpoints in nondiabetic individuals with overweight or obesity. Dedicated trials have also provided evidence for reduction in the risk for heart failure hospitalization and improvement in symptoms in individuals with heart failure with preserved ejection fraction. Subgroup analyses have suggested that GLP1RAs confer additive cardiorenal benefits irrespective of background medication use.Summary: There is increasing evidence that GLP1RA reduces the risk for cardiovascular events, chronic kidney disease progression, and heart failure hospitalizations. Further data on the effect of dual and triple GLP1-based therapies on cardiorenal outcomes is required.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It focuses on the role of hyperthermia in the development of acute kidney injury (AKI) and its potential progression to chronic kidney disease of nontraditional etiology (CKDnt). We highlight the physiological mechanisms by which hyperthermia affects kidney function and discuss emerging preventive strategies.Recent findings: Hyperthermia places the kidneys in a vulnerable state. As body temperature increases, blood flow is directed toward the skin to aid in cooling, diverting it away from internal organs like the kidneys to support blood pressure regulation. At the same time, hyperthermia and dehydration increases energetic demand to promote fluid and electrolyte conservation. Collectively, this can create a localized supply-demand mismatch, resulting in tissue hypoxia that can damage kidney tissues. These findings highlight that heat hyperthermia can lead to subclinical kidney damage, with potential long-term implications for kidney health.Summary: Heat-induced AKI is a growing public health concern. Individuals engaged in manual labor with prolonged exposure are at risk of CKDnt. Interventions aimed to prevent hyperthermia show promise in mitigating the risk of AKI. Further research is necessary to refine these strategies and establish evidence-based guidelines for reducing heat-related kidney injuries.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":" ","pages":"170-176"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142834065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of extreme weather events, climate change has also been implicated as an important mediator of adverse kidney health outcomes, not only increasing the risk for the development of acute and chronic kidney diseases, but also disrupting the delivery of critical kidney health services. In particular, the delivery of dialysis services during major emergencies remains an ongoing and increasing problem, with a recognized need for improved emergency preparedness and disaster management (EP-DM) strategies to mitigate the increased risk of morbidity and mortality associated with missed dialysis treatment.Recent findings: There are increasing reports detailing the challenges of kidney dialysis care in times of crisis, to include those resulting from both man-made and natural disasters. Optimized management of the high-risk vulnerable dialysis patient population must include both facility-facing comprehensive continuity of operations and emergency response plans, and ongoing patient-facing emergency preparedness education.Summary: This review discusses the adverse impact of climate change-related natural disasters on the delivery of dialysis services, and the evolving EP-DM strategies developed and implemented by the Veterans Health Administration (VA) to optimize the care and well being of the vulnerable end stage kidney disease (ESKD) patient population.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":" ","pages":"156-163"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ADPKD patients are prone to developing hypocitraturia in early stages, which could predispose to calcium microcrystal formation. Low urinary citrate excretion has been associated with a more rapid decline in eGFR and poorer renal survival in ADPKD patients. Animal studies employing citrate supplementation have shown promising effects on preserving the decline in estimated glomerular filtration rate (eGFR) and cyst growth.Summary: Current knowledge suggests that urinary citrate could be incorporated into existing prognostic markers for disease progression and potential adjuvant therapy in ADPKD, but further clinical studies to support such hypothesis must be undertaken.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":"34 2","pages":"138-142"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143058349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, there is a gap in identifying modifiable neighborhood factors, such as the built environment, in preventing CKD, that could be targets for feasible place-based interventions.Recent findings: Most published studies on neighborhood factors and CKD have focused on a single social attribute, such as neighborhood disadvantage, while research on the role of the built environment is more nascent. Early studies on this topic have yielded inconsistent results, particularly regarding whether food deserts are an environmental risk factor for CKD onset. International studies have shown that walkable neighborhoods - characterized by features such as urban design, park access, and green spaces - can be protective against both the onset and progression of CKD. However, these findings are inconclusive and understudied in the context of United States, where neighborhood environments differ from those in other countries.Summary: Future research on modifiable neighborhood factors and CKD using advanced study designs and population-representative datasets can yield stronger evidence on potential causal associations and suggest feasible place-based interventions as strategies for preventing CKD. As an example, we demonstrated the potential of electronic health record-based studies to advance research in this area.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":" ","pages":"143-150"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11779582/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142680116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
