More than 850 million individuals worldwide, accounting for 10–15% of the adult population, are estimated to have chronic kidney disease. Each of these individuals is host to tens of trillions of microorganisms that are collectively referred to as microbiota — a dynamic ecosystem that both influences host health and is itself influenced by changes in the host. Available evidence supports the existence of functional connections between resident microorganisms and kidney health that are altered in the context of specific kidney diseases, including acute kidney injury, chronic kidney disease and renal stone disease. Moreover, promising data from preclinical studies suggest that targeting of gut microbial pathways may provide new therapeutic opportunities for the treatment of kidney disease. This Roadmap describes current understanding of the mechanisms by which microorganisms regulate host organ function, the effects of kidney disease on the gut microbiome, and how these insights may contribute to the development of microbe-targeted therapeutics. We highlight key knowledge gaps that remain to be addressed and strategies for addressing these, outlining both the promise and the potential pitfalls of leveraging our understanding of the gut microbiota to better understand and treat kidney disease. Available evidence supports the existence of functional connections between resident microorganisms and the kidney that are altered in the context of specific kidney diseases. This Roadmap article describes current understanding of the mechanisms by which microorganisms regulate host organ function, highlighting key knowledge gaps that remain to be addressed and opportunities for future research.
据估计,全世界有超过8.5亿人患有慢性肾脏疾病,占成年人口的10-15%。这些个体中的每一个都是数万亿微生物的宿主,这些微生物被统称为微生物群——一个动态的生态系统,既影响宿主的健康,又受宿主变化的影响。现有证据支持,在特定肾脏疾病(包括急性肾损伤、慢性肾脏疾病和肾结石疾病)的情况下,常驻微生物与肾脏健康之间存在功能联系,这种联系会发生改变。此外,来自临床前研究的有希望的数据表明,靶向肠道微生物途径可能为肾脏疾病的治疗提供新的治疗机会。本路线图描述了微生物调节宿主器官功能的机制,肾脏疾病对肠道微生物组的影响,以及这些见解如何有助于微生物靶向治疗的发展。我们强调了仍有待解决的关键知识差距和解决这些问题的策略,概述了利用我们对肠道微生物群的理解来更好地理解和治疗肾脏疾病的前景和潜在缺陷。

The advent of immunotherapy has yielded great improvements in survival outcomes of people with clear-cell renal-cell carcinoma (ccRCC). Currently, immune checkpoint inhibitors (ICIs) are the cornerstone of treatment regimens for metastatic ccRCC. Yet a substantial group of patients do not respond to ICIs and few achieve long-term remission, indicating the presence of intrinsic and acquired resistance. The mechanisms underlying ICI resistance in ccRCC remain poorly understood, potentially owing to its unique immunological landscape compared with other immunotherapy-responsive cancers. Specifically, ccRCC is characterized by one of the highest levels of T cell infiltration across different tumours; however, high T cell infiltration does not correlate consistently with improved ICI outcomes. Moreover, the tumour mutational burden in ccRCC is relatively low, compared with that of other immunotherapy-responsive cancers, and fails to predict ICI efficacy. The limited predictive value of these commonly used markers for ICI response underscores the need for deeper exploration of the immunological mechanisms driving the antitumour immune response in ccRCC. Investigating commonalities and disparities with other immunotherapy-responsive cancer types might improve understanding of ICI resistance in ccRCC and inform the development of strategies to enhance the clinical benefits of immunotherapy. Although immune checkpoint inhibitors can prolong survival in people with clear-cell renal-cell carcinoma, disease progression is frequent. Here, the authors explore potential mechanisms that might drive intrinsic or acquired resistance to immune checkpoint inhibitors in clear-cell renal-cell carcinoma, including malignant cell-intrinsic and immune-cell factors.
免疫疗法的出现极大地改善了透明细胞肾细胞癌(ccRCC)患者的生存结果。目前,免疫检查点抑制剂(ICIs)是转移性ccRCC治疗方案的基础。然而,相当数量的患者对ICIs没有反应,很少有患者获得长期缓解,这表明存在内在和获得性耐药。与其他免疫治疗应答性癌症相比,ccRCC中ICI耐药的机制尚不清楚,这可能是由于其独特的免疫景观。具体来说,ccRCC的特点是不同肿瘤中T细胞浸润水平最高;然而,高T细胞浸润与改善ICI结果并不一致相关。此外,与其他免疫治疗应答性癌症相比,ccRCC的肿瘤突变负担相对较低,无法预测ICI的疗效。这些常用标志物对ICI反应的有限预测价值强调了对ccRCC中驱动抗肿瘤免疫反应的免疫学机制进行更深入探索的必要性。研究与其他免疫治疗反应性癌症类型的共性和差异可能会提高对ccRCC中ICI耐药性的理解,并为制定提高免疫治疗临床效益的策略提供信息。

Antigens in membranous nephropathy: discovery and clinical implications 膜性肾病抗原的发现及其临床意义
IF 39.8 1区 医学 Q1 UROLOGY & NEPHROLOGY Pub Date : 2025-07-21 DOI: 10.1038/s41581-025-00980-z

Membranous nephropathy is an autoimmune disease that results in an accumulation of antigen–antibody (IgG) immune complexes along the subepithelial region of the glomerular basement membrane and is the most common cause of nephrotic syndrome in adults. The diagnosis of membranous nephropathy is based on the presence of granular IgG on immunofluorescence microscopy and subepithelial electron dense deposits along the glomerular basement membrane on electron microscopy. Prior to 2009, the target antigen within the immune complexes was unknown. However, in the past 15 years, and in particular the past 5 years, several target antigens have been identified. These target antigens include PLA2R, THSD7A, EXT1 and EXT2, NELL1, SEMA3B, NCAM1, CNTN1, HTRA1, FAT1, PCDH7, NTNG1, PCSK6, NDNF and MPO. Several rare putative antigens have also been reported. These findings have transformed our understanding of membranous nephropathy from that of an idiopathic disease, which results from an autoimmune response to an unknown target antigen, to a disease in which a target antigen can be identified in ~80% of cases. Improved understanding of the distinctive clinical association, pathology and prognostic findings of each target antigen will have implications for clinical evaluation and therapeutic targeting in patients with membranous nephropathy. Since the discovery of PLA2R, several target antigens associated with membranous nephropathy have been identified. This Review describes the distinct clinical associations, pathology and prognostic findings associated with each of the identified target antigens and implications for the reclassification of membranous nephropathy.
膜性肾病是一种自身免疫性疾病,导致抗原抗体(IgG)免疫复合物沿肾小球基底膜上皮下区域积聚,是成人肾病综合征的最常见原因。膜性肾病的诊断是基于免疫荧光显微镜下颗粒状IgG的存在和电子显微镜下沿肾小球基底膜的上皮下电子致密沉积物。在2009年之前,免疫复合物内的靶抗原是未知的。然而,在过去的15年中,特别是在过去的5年中,已经确定了几个目标抗原。这些靶抗原包括PLA2R、THSD7A、EXT1和EXT2、NELL1、SEMA3B、NCAM1、CNTN1、HTRA1、FAT1、PCDH7、NTNG1、PCSK6、NDNF和MPO。一些罕见的推定抗原也被报道过。这些发现改变了我们对膜性肾病的认识,从一种由自身免疫反应对未知靶抗原引起的特发性疾病,转变为一种在约80%的病例中可以识别靶抗原的疾病。提高对每种靶抗原的独特临床关联、病理和预后结果的理解,将对膜性肾病患者的临床评估和治疗靶向具有重要意义。

Acute kidney injury (AKI) during pregnancy and the postpartum period, known as pregnancy-associated AKI (PrAKI), is an important health concern and driver of health inequity worldwide. Causes of PrAKI include sepsis, autoimmune disorders and pregnancy-specific pathologies such as hypertensive disorders. Common risk factors include maternal comorbidities and use of nephrotoxic medications. PrAKI accounts for a substantial proportion of maternal mortality and morbidity, particularly in low-income and middle-income countries, and may also adversely affect the fetus, resulting in death, premature birth and small for gestational age. In this Consensus Statement, we present recommendations on the causes, diagnosis, management and follow-up of PrAKI from the 32nd Acute Disease Quality Initiative meeting, which involved international experts in obstetrics, midwifery, obstetric medicine, paediatrics, internal medicine, anaesthesiology, nephrology and critical care. We suggest that pregnant and postpartum women at a high risk of PrAKI should be identified to enable prevention, surveillance and timely diagnosis. The multidisciplinary management of these patients should be tailored to treat their specific causes of PrAKI to optimize short-term and long-term neonatal and maternal outcomes. Further observational and interventional studies are needed to address existing gaps in knowledge of PrAKI and improve maternal and fetal outcomes. Pregnancy-associated acute kidney injury is a risk factor for maternal and fetal morbidity and mortality and a driver of health inequity worldwide. This Consensus Statement from the Acute Disease Quality Initiative provides recommendations on the causes, diagnosis, management and follow-up of pregnancy-associated acute kidney injury.
妊娠期和产后急性肾损伤(AKI),又称妊娠相关性AKI (PrAKI),是一个重要的健康问题,也是全球卫生不平等的驱动因素。PrAKI的病因包括败血症、自身免疫性疾病和妊娠特异性病理,如高血压疾病。常见的危险因素包括产妇合并症和使用肾毒性药物。PrAKI在孕产妇死亡率和发病率中占很大比例,特别是在低收入和中等收入国家,还可能对胎儿产生不利影响,导致死亡、早产和胎龄小。在本共识声明中,我们提出了来自第32届急性疾病质量倡议会议的关于PrAKI的病因、诊断、管理和随访的建议,该会议涉及产科、助产学、产科医学、儿科、内科、麻醉学、肾脏病学和重症监护方面的国际专家。我们建议应确定PrAKI高危孕妇和产后妇女,以便进行预防、监测和及时诊断。这些患者的多学科管理应量身定制,以治疗其PrAKI的具体原因,以优化短期和长期的新生儿和孕产妇结局。需要进一步的观察性和介入性研究来解决PrAKI知识的现有空白,并改善孕产妇和胎儿的结局。

Kidney health outcomes of hypertensive disorders of pregnancy 妊娠期高血压疾病对肾脏健康的影响
IF 39.8 1区 医学 Q1 UROLOGY & NEPHROLOGY Pub Date : 2025-07-18 DOI: 10.1038/s41581-025-00977-8

Hypertensive disorders of pregnancy (HDPs), including pre-eclampsia (PE), are frequent, affecting 8–10% and 2–4% of all pregnancies, respectively. Among HDPs, PE is the best characterized and most frequently studied — it is a heterogeneous disease with different clinical phenotypes reflecting distinct underlying mechanisms that ultimately result in widespread endothelial dysfunction and systemic damage. HDP clinical remission is common after delivery, but the long-term health of women with a history of HDP is adversely affected compared with that of women with normotensive pregnancies. The relationship between HDP and kidney health is bidirectional: chronic kidney disease (CKD) increases the risk of HDP, and HDP raises the risk of future CKD. To what extent this increased risk of CKD after HDP is due to pre-existing CKD that is unmasked by pregnancy and/or whether HDP is a causal factor in CKD remains unclear. CKD is diagnosed in up to 20% of women after PE, and the lifetime risk of kidney failure after one episode of PE is 4–8 times higher than that of the general population, increasing further with PE recurrence. These risks are cross generational, as women born prematurely from pregnancies complicated by PE and fetal growth restriction can have low nephron mass, which would not only increase their lifetime risk of CKD but also their risk of developing PE in their own pregnancies. This Review examines the bidirectional relationship between hypertensive disorders of pregnancy and kidney disease, which is currently underrecognized, with potential long-term implications for kidney health in both mothers and their offspring. The authors also discuss prevention and management of hypertensive disorders of pregnancy, including kidney health follow-up, and current research gaps.
妊娠高血压疾病(HDPs),包括先兆子痫(PE),是常见的,分别影响所有妊娠的8-10%和2-4%。在HDPs中,PE是最具特征和最常被研究的疾病,它是一种异质性疾病,具有不同的临床表型,反映了不同的潜在机制,最终导致广泛的内皮功能障碍和全身损伤。分娩后HDP临床缓解是常见的,但与正常妊娠妇女相比,有HDP病史的妇女的长期健康受到不利影响。HDP与肾脏健康之间的关系是双向的:慢性肾脏疾病(CKD)增加HDP的风险,而HDP增加未来CKD的风险。在多大程度上,HDP后CKD的风险增加是由于妊娠暴露的已有CKD和/或HDP是否是CKD的一个因果因素尚不清楚。高达20%的女性在PE后被诊断为CKD,一次PE后肾衰竭的终生风险是一般人群的4-8倍,随着PE的复发进一步增加。这些风险是跨代的,因为妊娠合并PE和胎儿生长受限的早产妇女的肾单位质量可能较低,这不仅会增加她们一生中患CKD的风险,也会增加她们自己妊娠时患PE的风险。

Among HDPs, PE is the best characterized and most frequently studied — it is a heterogeneous disease with different clinical phenotypes reflecting distinct underlying mechanisms that ultimately result in widespread endothelial dysfunction and systemic damage. HDP clinical remission is common after delivery, but the long-term health of women with a history of HDP is adversely affected compared with that of women with normotensive pregnancies. The relationship between HDP and kidney health is bidirectional: chronic kidney disease (CKD) increases the risk of HDP, and HDP raises the risk of future CKD. To what extent this increased risk of CKD after HDP is due to pre-existing CKD that is unmasked by pregnancy and/or whether HDP is a causal factor in CKD remains unclear. CKD is diagnosed in up to 20% of women after PE, and the lifetime risk of kidney failure after one episode of PE is 4–8 times higher than that of the general population, increasing further with PE recurrence. These risks are cross generational, as women born prematurely from pregnancies complicated by PE and fetal growth restriction can have low nephron mass, which would not only increase their lifetime risk of CKD but also their risk of developing PE in their own pregnancies.

The involvement of patients with lived experience of kidney disease in nephrology research can strengthen the relevance and uptake of evidence to achieve better outcomes. The past two decades have seen increased efforts to involve patients and caregivers, particularly in research priority setting, study design and dissemination. However, further efforts are needed to improve the transparency and diversity of patient involvement in research.
有肾脏疾病生活经验的患者参与肾脏学研究可以加强证据的相关性和吸收,以获得更好的结果。在过去的二十年里,我们已经加大了让患者和护理人员参与的努力,特别是在研究重点的确定、研究设计和传播方面。然而,需要进一步努力提高患者参与研究的透明度和多样性。

The catastrophic costs of chronic kidney disease 慢性肾脏疾病的灾难性代价
IF 39.8 1区 医学 Q1 UROLOGY & NEPHROLOGY Pub Date : 2025-07-02 DOI: 10.1038/s41581-025-00978-7

Chronic kidney disease (CKD) is associated with the highest occurrence of catastrophic healthcare expenditure (CHE) both globally and across all diseases. However, CHE alone does not provide a complete measure of the financial burdens of CKD on a household, especially for those with very low incomes or who forego therapy altogether. A more comprehensive assessment of direct, indirect and long-term costs is crucial to advancing equitable and effective universal health coverage.
慢性肾脏疾病(CKD)是全球和所有疾病中灾难性医疗支出(CHE)发生率最高的疾病。然而,单独的CHE并不能提供一个完整的衡量CKD对家庭的经济负担,特别是对于那些收入非常低或完全放弃治疗的家庭。更全面地评估直接、间接和长期成本对于促进公平和有效的全民健康覆盖至关重要。
