Occupational risks associated with chronic kidney disease of non-traditional origin (CKDnt) in Brazil: it is time to dig deeper into a neglected problem. J Bras Nefrol 2024; 46:e20230123. [PMID: 38591822 PMCID: PMC11248720 DOI: 10.1590/2175-8239-jbn-2023-0123en] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 12/14/2023] [Indexed: 04/10/2024] Open
Abstract
In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD's etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety.

Urine Metabolomic Signature of People Diagnosed with Balkan Endemic Nephropathy and Other Types of Chronic Kidney Disease Compared with Healthy Subjects in Romania. Metabolites 2023; 13:metabo13050609. [PMID: 37233650 DOI: 10.3390/metabo13050609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 04/23/2023] [Accepted: 04/27/2023] [Indexed: 05/27/2023] Open
Abstract
Metabolomic analysis methods were employed to determine biomarkers for various chronic kidney diseases (CKDs). Modern analytical methods were developed and applied successfully to find a specific metabolomic profile in urine samples from CKD and Balkan endemic nephropathy (BEN) patients. The aim was to explore a specific metabolomic profile defined by feasible/easy-to-identify molecular markers. Urine samples were collected from patients with CKDs and BEN, and from healthy subjects from endemic and nonendemic areas in Romania. Metabolomic analysis of urine samples, extracted by the liquid-liquid extraction (LLE) method, was performed by gas chromatography-mass spectrometry (GC-MS). The statistical exploration of the results was performed through a principal component analysis (PCA) evaluation. Urine samples were statistically analyzed using a classification based on six types of metabolites. Most urinary metabolites are distributed in the center of a loading plot, meaning that these compounds do not represent significant markers for BEN. One of the most frequent and higher-concentration urinary metabolites in BEN patients was p-Cresol, a phenolic compound that implies a severe injury of the renal filtration function. The presence of p-Cresol was associated with protein-bound uremic toxins, which have specific functional groups such as indole and phenyl. In prospective studies for future investigation, prevention, and disease treatment, we suggest a larger sample size, sample extraction using other methods, and analysis using other chromatography techniques coupled with mass spectrometry, which can generate a more significant data set for statistical analysis.

Figueroa-Solis E, Gimeno Ruiz de Porras D, Rojas-Garbanzo M, Whitehead L, Zhang K, Delclos GL. Prevalence and Geographic Distribution of Self-Reported Chronic Kidney Disease and Potential Risk Factors in Central America. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1308. [PMID: 36674063 PMCID: PMC9859154 DOI: 10.3390/ijerph20021308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/07/2023] [Accepted: 01/09/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND Cases for chronic kidney disease of unknown etiology (CKDu) are increasing in specific disease hotspots located in rural agricultural communities over Central America. The goal of the study was to estimate the prevalence and geographic distribution of self-reported work-related CKD and associated risk factors for CKDu by industry sector in Central America. METHODS We calculated the prevalence and distribution of self-reported CKD, work-related CKD, and suspected CKDu risk factors among the 9032 workers in the Second Central American Survey of Working Conditions and Health (II ECCTS, 2018). We mapped the distribution of suspected CKDu risk factors to work-related CKDu and weather conditions using average annual temperatures. RESULTS The primary and secondary industry sectors showed the highest proportion of males, suspected CKDu risk factors, and work-related CKD. Age (30-49 years: OR = 2.38, 95% CI 1.03-5.51), ethnicity (mestizo: OR, 7.44, 95% CI: 2.14-25.82), and exposure to high physical work demands (OR = 2.45, 95% CI: 1.18-5.09) were associated with work-related CKD. The majority of work-related CKD were reported in the western parts of Honduras and Nicaragua, in hot temperature regions, and overlapped with those areas with a high density of CKDu risk factors. Finally, some areas clustered CKDu risk factors without any work-related CKD points, mainly in the western part of Guatemala. CONCLUSION Our findings supplement prior CKDu findings regarding a high prevalence of work-related CKD among 30- to 49-year-old mestizo males in the primary and secondary sectors, in hot temperature areas, in the central and western region, and overlapping with persons reporting two or more CKDu risk factors. Moreover, several geographic areas with CKDu risk factor clusters had no reported work-related CKD. These areas represent new industries and sectors to be monitored for possible future increases of CKDu cases.

Abstract
There is a limited understanding of how toxic exposures to agrichemicals vary relative to international migration over the life course. A life history calendar (LHC) was piloted to explore sequences of agrichemical exposure relative to international migration. LHCs were administered to 41 foreign born individuals from Mexico and Central America who had agricultural work experience during their lifetime and who were living in South Florida. Social sequence analysis was used to explore occupation-by-agrichemical events relative to migration. A three-cluster solution was used to classify low, moderate, and high lifetime exposure sequences. The odds of any perceived effects of agrichemicals on the body increased with time prior to migration in the moderate and high exposure sequence clusters and continued to increase 20% with each year following migration in the moderate exposure cluster. Workers with high lifetime agrichemical exposures prior to migrating internationally showed lower likelihoods of a perceived effect on the body following migration despite continued exposure. Further research on instrument validity is warranted.

Aristolochic acid I as an emerging biogenic contaminant involved in chronic kidney diseases: A comprehensive review on exposure pathways, environmental health issues and future challenges. CHEMOSPHERE 2022; 297:134111.

Abstract
Described in the 1950s, Balkan Endemic Nephropathy (BEN) has been recognized as a chronic kidney disease (CKD) with clinical peculiarities and multiple etiological factors. Environmental contaminants - aromatic compounds, mycotoxins and phytotoxins like aristolochic acids (AAs) - polluting food and drinking water sources, were incriminated in BEN, due to their nephrotoxic and carcinogenic properties. The implication of AAs in BEN etiology is currently a highly debated topic due to the fact that they are found within the Aristolochiaceae plants family, used around the globe as traditional medicine and they were also incriminated in Aristolochic Acid Nephropathy (AAN). Exposure pathways have been investigated, but it is unclear to what extent AAs are acting alone or in synergy with other cofactors (environmental, genetics) in triggering kidney damage. Experimental studies strengthen the hypothesis that AAI, the most studied compound in the AAs class, is a significant environmental contaminant and a most important causative factor of BEN. The aim of this review is to compile information about the natural exposure pathways to AAI, via traditional medicinal plants, soil, crop plants, water, food, air. Data that either supports or contradicts the AAI theory concerning BEN etiology was consolidated and available solutions to reduce human exposure were discussed. Because AAI is a phytotoxin with physicochemical properties that allow its transportation in environmental matrices from different types of areas (endemic, nonendemic), and induce CKDs (BEN, AAN) and urinary cancers through bioaccumulation, this review aims to shed a new light on this compound as a biogenic emerging pollutant.

Ortiz A. Benchmarking CKD: incidence of CKD in a European country with low prevalence of chronic kidney disease and of kidney replacement therapy. Clin Kidney J 2022; 15:1221-1225.

Abstract
Iceland was one of six European countries with an adjusted incidence of kidney
replacement therapy (KRT) in 2018 lower than 100 per million persons (pmp), along with
Estonia, Montenegro, Russia, Serbia and Finland. It was also one of 10 countries with an
adjusted KRT prevalence <900 pmp. Furthermore, the prevalence of chronic kidney disease
(CKD) in Iceland is up to 2.44-fold lower and the death rate from CKD up to 3.44-fold
lower than in other countries with a low incidence of KRT, suggesting that the low KRT
incidence actually reflects a low need for KRT rather than low uptake or availability of
KRT. This identifies Iceland as a benchmark for countries trying to reduce KRT incidence.
Iceland also represents one of the best genetically characterized populations in the
world, facilitating studies on the influence of the genetic background versus environment
and lifestyle on CKD. This issue of CKJ reports the incidence and risk
factors for CKD in Icelandic adults. Diabetes, acute kidney injury, hypertension,
cardiovascular disease, chronic lung disease, malignancy and major psychiatric illness
were associated with an increased risk of incident CKD, as were obesity and sleep apnea in
women. However, in 75% of incident CKD cases, CKD was first detected in category G3 or
higher, emphasizing the need for new tools that allow an earlier diagnosis of CKD that
precedes the loss of >50% of the functioning kidney mass and/or wider use of
albuminuria as a screening tool. The European Society of Cardiology just recommended
assessing albuminuria for routine cardiovascular risk workups for all.

Abstract
The year 2021 was the last full year of Alberto Ortiz’s editorship at Clinical Kidney Journal (CKJ). On May 2022, Maria José Soler will start her term as the Editor-in-Chief. Over these years, CKJ obtained its first journal impact factor and has consolidated its position among the top journals in the field, consistently ranking among the top 25% (first quartile) journals in Urology and Nephrology. The 2020 journal impact factor rose to 4.45, becoming the top open access journal in Nephrology and the ninth ranked Nephrology journal overall. We now review the recent history of the journal and the most highly cited topics which include the epidemiology of kidney disease, chronic kidney disease topics, such as the assessment and treatment of chronic kidney disease, onconephrology, cardionephrology, glomerular disease, transplantation and coronavirus disease 2019 (COVID-19).

Abstract
The uptake of the current concept of chronic kidney disease (CKD) by the public, physicians and health authorities is low. Physicians still mix up CKD with chronic kidney insufficiency or failure. In a recent manuscript, only 23% of participants in a cohort of persons with CKD had been diagnosed by their physicians as having CKD while 29% has a diagnosis of cancer and 82% had a diagnosis of hypertension. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. A prevalent view is that for those in whom kidneys fail, the problem is "solved" by dialysis or kidney transplantation. However, the main burden of CKD is accelerated aging and all-cause and cardiovascular premature death. CKD is the most prevalent risk factor for lethal COVID-19 and the factor that most increases the risk of death in COVID-19, after old age. Moreover, men and women undergoing KRT still have an annual mortality which is 10-100-fold higher than similar age peers, and life expectancy is shortened by around 40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth global cause of death by 2040 and the second cause of death in Spain before the end of the century, a time when 1 in 4 Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded CIBER network research structure in Spain. Leading Spanish kidney researchers grouped in the kidney collaborative research network REDINREN have now applied for the RICORS call of collaborative research in Spain with the support of the Spanish Society of Nephrology, ALCER and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true. However, only the highest level of research funding through the CIBER will allow to adequately address the issue before it is too late.

Abstract
Amongst the many threats to health in our world, the most challenging ones are the ones with unknown causes. There is a mysterious epidemic of kidney disease called chronic kidney disease of unknown etiology (CKDu) that is occurring in many parts of the world. Unrelated to known risk factors such as diabetes and hypertension, CKDu mostly affects the young and middle-aged, with slight preponderance in males. It mostly occurs in people living in rural areas, especially working in agricultural jobs. Worldwide, the number of people with chronic kidney disease, and those who need dialysis and renal replacement, is increasing every year as compared to other chronic conditions like diabetes and AIDS. It's not just alarming but a great challenge to healthcare systems across the world, especially in resource-poor countries. CKDu has become a silent killer for most patients. The occurrence of end-stage renal disease (ESRD) in CKDu can be catastrophic for individuals, especially in countries with limited medical facilities, causing a significant socio-economic burden. Even within these economically developing nations, people affected by CKDu usually are from the most vulnerable and underserved populations. As a definitive etiology has not been postulated for CKDu to date, this comprehensive review was undertaken to throw light on the poorly understood epidemiologic risk factors and the course of the disease.

Abstract
Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is ‘solved’ by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020–2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true.

Abstract
Central Australia is a human T-cell leukemia virus type 1c (HTLV-1c) endemic region and has the highest incidence of chronic kidney disease (CKD) in Australia. The factors associated with HTLV-1 seropositivity among Aboriginal Australian adults with CKD receiving hemodialysis (HD) were determined. A retrospective observational study of Aboriginal adults (≥ 18 years) who were receiving regular HD at the two main dialysis units in Alice Springs, December 1, 2010 to December 31, 2015. Demographic and clinical data before commencing HD were extracted from hospital records from the first presentation to Alice Springs Hospital (ASH) to HD commencement and associations were determined using logistic regression. Among 373 patients receiving HD, 133 (35.9%) were HTLV-1 infected. Identifiable factors associated with HTLV-1 status included increasing age, male gender, and diabetes before HD. The odds of diabetes mellitus were significantly higher among patients with HTLV-1 (adjusted odds ratio [aOR]: 2.76, 95% confidence interval [CI]: 1.19, 6.39; p = 0.017). More than one-fifth of participants had an acute kidney injury, the risk of which was increased among those with a previous blood stream infection (aOR: 3.02, 95% CI: 1.71, 5.34, p < 0.001). Men with a high HTLV-1 proviral load (≥500 copies per 105 peripheral blood leukocytes) had an increased risk of urinary tract infection (UTI) before HD (aOR: 5.15, 95% CI: 1.62, 16.40; p = 0.006). A strong association between HTLV-1 and diabetes, and an increased risk of UTI among men with a high HTLV-1 PVL, suggest that interactions between HTLV-1 infection and conventional risk factors may increase the risk for CKD in this population.

Abstract
Chronic kidney disease (CKD) has become one of the most important public health problems worldwide. Analysis, and understanding, of this global/national/regional reality would benefit from renal registry databases. The implementation of a CKD registry (including all categories) is difficult to achieve, given its high cost. On the other hand, patients with end-stage kidney disease (ESKD) are easily accessible and constitute the most severe subgroup in terms of comorbidities and healthcare costs. A kidney replacement therapy registry (KRTR) is defined as the systematic and continuous collection of a population-based data set from ESKD patients treated by dialysis/kidney transplant. The lack of available data, particularly in emerging economies, leaves information gaps on healthcare and outcomes in these patients. The heterogeneity/absence of a KRTR in some countries is consistent with the inequities in access to KRT worldwide. In 2014, the Pan American Health Organization (PAHO) proposed to determine the prevalence of patients on dialysis for at least 700 patients per million inhabitants by 2019 in every Latin American (LA) country. Since then, PAHO and the Sociedad LatinoAmericana de Nefrología e Hipertensión have provided training courses and certification of KRTR in LA. The purpose of this manuscript is to provide guidance on how to set up a new KRTR in countries or regions that still lack one. Advice is provided on the sequential steps in the process of setting up a KRTR, personnel requirements, data set content and minimum quality indicators required.

Abstract
Background Chronic kidney disease (CKD) is one of the pathologies with the greatest impact on the public health system. Over the last few decades, the relevance of CKD in Mexico has increased, with associated overwhelming costs for care of renal disease. There are no reliable CKD statistics in Mexico. Methodology In June 2018, the government of Aguascalientes called on all Health Institutions to create a state registry of treated end-stage renal disease (ESRD). In the same system, a renal biopsy result registry included all the native kidney biopsies obtained in the state of Aguascalientes since 2012. We herein describe the prevalence, incidence and characteristics of the patients included in the CKD and renal biopsy registry in the state of Aguascalientes. Results As of April 2020, the state has documented 2827 patients on renal replacement therapy (RRT), 1877 on dialysis and 950 that have been transplanted. The prevalence of patients on dialysis is 1326 per million population (p.m.p.), and if transplanted individuals are included, it is 1997 p.m.p. The incidence of treated ESRD in 2019 was 336 p.m.p. (n = 474) in individuals with an average age of 45.6 years (standard deviation ±18), and in a higher proportion of men (61%). There is a bimodal distribution of the age at which RRT was initiated. The first and the most significant peaks are between the ages of 20 and 40 years and are usually the result of CKD of unknown cause (73%). The second peak is between 50 and 70 years of age, and CKD is usually the result of diabetes mellitus and systemic arterial hypertension (59.6%). Since January 2012, 423 biopsies have been recorded. The patient’s ages were between 20 and 30 years (n = 112), and the most frequent diagnosis was focal segmental glomerulosclerosis (FSGS) (54%). Conclusions The prevalence of treated ESRD in the state of Aguascalientes is high. The disease mostly afflicts young people between 20 and 40 years of age, and there is a clear male predominance. In this age group, the main clinical diagnosis is CKD of unknown origin, and the most frequent biopsy diagnosis was FSGS.

Restricted Water Intake and Hydration with Fructose-Containing Beverages during Infancy Predispose to Aggravate an Acute Renal Ischemic Insult in Adolescent Rats. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4281802.

Abstract
We aimed to investigate the effects of chronic fluid restriction and hydration with a sweetened beverage (SB) in rats from weaning until adolescence, in a posterior acute kidney injury (AKI) event induced by ischemia-reperfusion (I/R). We followed 5 groups of weaning rats: control group (C); two groups with 22 h/day fluid restriction, a group hydrated for two hours with water (-W) and a group hydrated with SB; one group receiving SB ad libitum all day (+SB); and one group in which water consumption was increased using a gel diet. The rats that reached adolescence were submitted to I/R. Fluid restriction and/or SB hydration induced mild renal alterations that were significantly accentuated in the -SB group and resulted in worse outcomes after I/R-induced AKI that resulted in a catastrophic fall in creatinine clearance and diffuse acute tubular necrosis. In summary, low tap water intakes, as well as SB intake in infancy, prompt kidney worse outcomes in a later event of AKI during adolescence and both insults magnify kidney damage. Studies on hydration habits in children are recommended to disclose the potentially harmful effects that those behavioral patterns might carry to future renal health.

Abstract
BACKGROUND Studies have described Mesoamerican nephropathy among agricultural workers of El Salvador and northwestern Nicaragua. Data on prevalence and risk factors for CKD beyond agricultural workers and in other regions in Nicaragua are sparse. METHODS We recruited participants from 32 randomly selected communities in the Department of Rivas's ten municipalities in two phases. In phase 1, we screened participants using a field-based capillary creatinine measuring system and collected self-reported information on lifestyle and occupational, exposure, and health histories. Two years later, in phase 2, we enrolled 222 new participants, performing serum creatinine testing in these participants and confirmatory serum creatinine testing in phase 1 participants. RESULTS We enrolled 1242 of 1397 adults (89%) living in 533 households (median age 41 years; 43% male). We confirmed CKD (eGFR<60 ml/min per 1.73 m2) in 53 of 1227 (4.3%) evaluable participants. In multivariable testing, risk factors for prevalent CKD included age (odds ratio [OR], 1.92; 95% confidence interval [95% CI], 1.89 to 1.96) and self-reported history of hypertension (OR, 1.95; 95% CI, 1.04 to 3.64), diabetes (OR, 2.88; 95% CI, 1.40 to 5.93), or current or past work in the sugarcane industry (OR 2.92; 95% CI, 1.36 to 6.27). CONCLUSIONS Adjusted CKD prevalence was about 5% with repeat confirmatory testing in southwest Nicaragua, lower than in the northwest region. Risk factors included diabetes, hypertension, and current or prior work in the sugarcane industry but not in other forms of agricultural work. Formal CKD surveillance programs in Nicaragua are needed to assess the overall burden of CKD nationally, with a focus on agricultural workers.

Design and optimization strategies for the development of new drugs that treat chronic kidney disease. Expert Opin Drug Discov 2019; 15:101-115.

Abstract
Introduction: Chronic kidney disease (CKD) is characterized by increased risks of progression to end-stage kidney disease requiring dialysis and cardiovascular mortality, predicted to be among the five top causes of death by 2040. Only the design and optimization of novel strategies to develop new drugs to treat CKD will contain this trend. Current therapy for CKD includes nonspecific therapy targeting proteinuria and/or hypertension and cause-specific therapies for diabetic kidney disease, autosomal dominant polycystic kidney disease, glomerulonephritides, Fabry nephropathy, hemolytic uremic syndrome and others.Areas covered: Herein, the authors review the literature on new drugs under development for CKD as well as novel design and development strategies.Expert opinion: New therapies for CKD have become a healthcare priority. Emerging therapies undergoing clinical trials are testing expanded renin-angiotensin system blockade with double angiotensin receptor/endothelin receptor blockers, SGLT2 inhibition, and targeting inflammation, the immune response, fibrosis and the Nrf2 transcription factor. Emerging therapeutic targets include cell senescence, complement activation, Klotho expression preservation and microbiota. Novel approaches include novel model systems that can be personalized (e.g. organoids), unbiased systems biology-based identification of new therapeutic targets, drug databases that speed up drug identification and repurposing, nanomedicines that improve drug delivery and RNA targeting to expand the number of targetable proteins.

Moreover, this effect has been associated with upregulation of the polyol–fructokinase pathway and increased renal oxidative stress. Previously, we have shown that pharmacological inhibition of both V1a and V2 vasopressin receptors with conivaptan improved such renal alterations. The aim of this study was to evaluate the independent contributions of V1a and V2 receptors to the renal damage caused by mild heat stress and limited rehydration with a fructose-containing beverage. Osmotic minipumps were used to deliver either relcovaptan (0.64 mg/day) or tolvaptan (0.25 mg/day) in male Wistar rats for two weeks. Corresponding dilution vehicles were used as controls. To induce dehydration, rats were exposed to mild heat stress (37 °C for 1 h, Monday to Friday). All groups received a 10% fructose solution as a rehydration fluid for 2 h after mild heat stress. For the remainder of the day and on weekends, rats received tap water. The independent blockade of either the V1a or the V2 receptor prevented renal damage, reduced oxidative stress, and decreased plasma cortisol and systemic inflammation. However, the beneficial effects were regulated by different mechanisms. Tolvaptan inhibited polyol–fructokinase pathway overactivation, while relcovaptan prevented upregulation of the renin–angiotensin system and SGK1 expression. These data suggest that both V1a and V2 receptors participate in renal damage caused by heat stress-induced dehydration when fructose-containing beverages are used as rehydration fluids.

Abstract
An epidemic of chronic kidney disease of unknown etiology (Mesoamerican nephropathy) has emerged in hot regions of Central America. We have demonstrated that dehydration associated with recurrent heat exposure causes chronic kidney disease in animal models. However, the independent influence of core body temperature on kidney injury has not been explored. In the present study, we tested the hypothesis that kidney injury could be accelerated by increasing body temperature independent of external temperature. Wild-type mice were exposed to heat (39.5°C, 30 min, 2 times daily) with or without the mitochondrial uncoupling agent 2,4-dinitrophenol (DNP) for 10 days. Core temperature, renal function, proteinuria, and renal histological and biochemical analyses were performed. Isolated mitochondria markers of oxidative stress were evaluated from kidney tissue. DNP increased body core temperature in response to heat by 1°C (42 vs. 41°C), which was transient. The mild increase in temperature correlated with worsening albuminuria (R = 0.715, P < 001), renal tubular injury, and interstitial infiltration of monocytes/macrophages. Tubular injury was marked in the outer medulla. This was associated with a reduction in kidney tissue ATP levels (nonheated control: 16.71 ± 1.33 nmol/mg and DNP + heat: 13.08 ± 1.12 nmol/mg, P < 0.01), reduced mitochondria, and evidence for mitochondrial oxidative stress. The results of the present study suggest that kidney injury in heat stress is markedly worsened by increasing core temperature. This is consistent with the hypothesis that clinical and subclinical heat stroke may play a role in Mesoamerican nephropathy.

Abstract
AIM Kidney disease of unknown aetiology (CKDu) has been a health problem in the rural farming community of the North Central province of Sri Lanka since the 1990s and various environmental factors have been postulated as contributing factors for this disease. The aim of our study was to find out whether farmers undergo dehydration which would lead to concentration of urine and the water soluble potentially toxic substance in the kidney, leading to damage of the renal tubules. Therefore, we studied a sample of healthy farmers who were CKDu-free to determine whether they were dehydrated. METHODS Sample included healthy male paddy farmers of Padaviya in the Anuradhapura district. Plasma and urine osmolarity were recorded upon waking up in the morning and evening during the non-farming and farming seasons. Basic statistics and a 2 × 2 anova was done to test the interaction of time of day with farming activity. RESULTS Farmers were dehydrated according to the plasma osmolarity especially in the mornings, irrespective of whether they were farming or not. Approximately 40% of the sample also demonstrated acute dehydration at the end of the day due to farming activity as indicated by both plasma and urine osmolarity and specific gravity. CONCLUSION This study revealed that the farmers of the Padaviya area were either dehydrated or at the upper limit of euhydration sometime during the day irrespective of their activities during the day.

Abstract
Emergence of a new form of chronic kidney disease (CKD) of unknown etiology (CKDu) during the last 2 decades has resulted in considerable morbidity and mortality among the agricultural community residing in the north central region of Sri Lanka. A 3-level epidemiological case definition to identify CKDu in Sri Lanka was developed and published by the Ministry of Health in November 2016. The Sri Lanka Society of Nephrology (SLSON) refined the definition through a consensus of experts using a systematic approach in August 2017. An initial consultative meeting with the participation of 31 experts, including nephrology specialists, experts on primary care and epidemiology, and policy and university academics with long-standing experience in CKDu research, was held to identify the gaps in the existing definition. Following the meeting, a facilitator conducted 2 rounds of remote consultations using the Delphi method to obtain consensus of the participants on suggestions to improve the existing case definition. The process was initiated in August 2017 and was completed in April 2018 and resulted in the participants agreeing to a refined multilevel clinical case definition for CKDu to be used in surveillance and epidemiological studies. This article describes the process used and development of this new case definition for CKDu in Sri Lanka.

Abstract
The 2019 International Society of Nephrology World Kidney Day theme is Kidney Health for Everyone Everywhere. It focuses on the uneven burden of acute kidney injury and chronic kidney disease (CKD) in different communities, identifies disparities and challenges in access to care and calls for universal health coverage for prevention and early treatment of kidney disease. This topic is fully in line with the Clinical Kidney Journal (ckj) editorial strategy for improving worldwide kidney care without leaving any community behind. Indeed, the first PubMed-recorded use of the term CKD hotspot was in ckj, where it was defined as 'countries, region[s], communities or ethnicities with higher than average incidence of CKD'. This issue of ckj contains the World Kidney Day editorial as well as contributions that illustrate two concepts: the need to validate biochemical thresholds generated in developed countries in other populations, as exemplified by Kidney Disease: Improving Global Outcomes CKD-mineral and bone disorder parameters in an African population, and the fact that some disease associations characteristic of developing countries may be described initially in developed countries, as exemplified by the association of APOL1 variants with CKD or by minimal change disease secondary to malaria, but have to be validated locally.

Abstract
Kidney disease is a global public health problem, affecting over 750 million persons worldwide. The burden of kidney disease varies substantially across the world, as does its detection and treatment. In many settings, rates of kidney disease and the provision of its care are defined by socio-economic, cultural, and political factors leading to significant disparities. World Kidney Day 2019 offers an opportunity to raise awareness of kidney disease and highlight disparities in its burden and current state of global capacity for prevention and management. Here, we highlight that many countries still lack access to basic diagnostics, a trained nephrology workforce, universal access to primary health care, and renal replacement therapies. We point to the need for strengthening basic infrastructure for kidney care services for early detection and management of acute kidney injury and chronic kidney disease across all countries and advocate for more pragmatic approaches to providing renal replacement therapies. Achieving universal health coverage worldwide by 2030 is one of the World Health Organization's Sustainable Development Goals. While universal health coverage may not include all elements of kidney care in all countries, understanding what is feasible and important for a country or region with a focus on reducing the burden and consequences of kidney disease would be an important step towards achieving kidney health equity.

Abstract
Chronic kidney disease of unknown aetiology (CKDu) refers to the epidemic level of incidence of CKD in several low- and middle-income countries, usually near the equator, for which the aetiology has not been identified. CKDu represents a form of CKD hotspot, defined as a country, region, community or ethnicity with a higher than average incidence of CKD. In terms of the number of persons affected, the so-called hypertensive nephropathy of African Americans probably represents the largest CKD hotspot, which is largely driven by variants of the APOL1 gene, questioning the very existence of hypertensive nephropathy and illustrating how kidney disease driven by genetic predisposition may underlie some forms of hypertension. For CKDu, hard physical work leading to dehydration (the first global warming-related disease?) and local toxins are leading aetiological candidates. Meso-American nephropathy is probably the best-characterized CKDu. In this issue of CKJ, a systematic review and meta-analysis by Gonzalez et al. identified positive associations between Meso-American nephropathy and male gender, family history of CKD, high water intake and lowland altitude. We now discuss the potential relationship of family history to genetic predisposition and how a better understanding of CKDu may help advance the aetiological characterization of the nearly 50% of end-stage renal disease patients worldwide that have no known cause for CKD or have been assigned non-specific diagnoses.

Abstract
Little is known regarding the ways in which chronic kidney disease (CKD) prevalence and progression differ between the sexes. Still less is known regarding how social disparities between men and women may affect access to care for CKD. In this review, we briefly describe biological sex differences, noting how these differences currently do not influence CKD management recommendations. We then describe what is known within the published literature regarding differences in CKD epidemiology between sexes; namely prevalence, progression, and access to treatment throughout the major world regions. We highlight that health care expenditure and social gender disparities ultimately may determine whether women have equitable access to care for CKD and end-stage kidney disease. Among many high- and low-income settings, women more often donate and are less likely to receive kidney transplants when compared with men. Research is needed urgently to elucidate the reasons behind these disparities, as well as to develop CKD treatment strategies tailored to women's unique health care needs.

Abstract
Introducción En 2013, los Estados Miembros de la OPS reconocieron la epidemia de enfermedad renal crónica de causas no tradicionales (ERCnT) como un grave problema de salud pública. Este artículo describe el establecimiento de prioridades de investigación para abordar de manera integral la ERCnT en Centroamérica. Métodos Se estructuró una encuesta virtual utilizando la metodología Delphi mediante una búsqueda de estudios de investigación efectuados en Centroamérica y de agendas de investigación previas sobre la ERC. Los encuestados se identificaron en diversas fuentes. La primera ronda buscó refinar y añadir tópicos de investigación y priorizar los más relevantes. La segunda ronda priorizó los tópicos más relevantes. Se realizó un análisis por fuzzy sets para estimar umbrales de decisión y puntajes por tópico. Resultados La encuesta se envió a 83 personas de habla hispana y 38 de habla inglesa y respondió 46,2%. Para la segunda ronda, se envió la encuesta a 56 personas en español y 16 en inglés que habían contestado a la la primera. Se priorizaron 18 tópicos de investigación enmarcados en 10 áreas: políticas públicas, determinantes, etiología, diagnóstico y tratamiento de la ERC, prevención primaria, prestación de servicios, recursos humanos, sistemas de información y financiamiento. Se comprobó que la investigación en ERCnT es escasa y está restringida a ciertos tópicos. Conclusiones Además de los factores etiológicos, se dio gran relevancia a aspectos relacionados con la respuesta de los sistemas de salud, incluidos el abordaje de la prestación de servicios, los recursos humanos, el financiamiento y aspectos ocupacionales y ambientales.

Abstract
In order to change the current state of chronic kidney disease knowledge and therapeutics, a fundamental improvement in the understanding of genetic and environmental causes of chronic kidney disease is essential. This article first provides an overview of the existing knowledge gaps in our understanding of the genetic and environmental causes of chronic kidney disease, as well as their interactions. The second part of the article formulates goals that should be achieved in order to close these gaps, along with suggested timelines and stakeholders that are to be involved. A better understanding of genetic and environmental factors and their interactions that influence kidney function in healthy and diseased conditions can provide novel insights into renal physiology and pathophysiology and result in the identification of novel therapeutic or preventive targets to tackle the global public health care problem of chronic kidney disease.

Abstract
Millions of workers around the world are exposed to high temperatures, intense physical activity, and lax labor practices that do not allow for sufficient rehydration breaks. The extent and consequences of heat exposure in different occupational settings, countries, and cultural contexts is not well studied. We conducted an in-depth review to examine the known effects of occupational heat stress on the kidney. We also examined methods of heat-stress assessment, strategies for prevention and mitigation, and the economic consequences of occupational heat stress. Our descriptive review summarizes emerging evidence that extreme occupational heat stress combined with chronic dehydration may contribute to the development of CKD and ultimately kidney failure. Rising global temperatures, coupled with decreasing access to clean drinking water, may exacerbate the effects of heat exposure in both outdoor and indoor workers who are exposed to chronic heat stress and recurrent dehydration. These changes create an urgent need for health researchers and industry to identify work practices that contribute to heat-stress nephropathy, and to test targeted, robust prevention and mitigation strategies. Preventing occupational heat stress presents a great challenge for a concerted multidisciplinary effort from employers, health authorities, engineers, researchers, and governments.

Abstract
The KDIGO definition of chronic kidney disease (CKD) allowed a more detailed characterization of CKD causes, epidemiology and consequences. The picture that has emerged is worrisome from the point of view of translation. CKD was among the fastest growing causes of death in the past 20 years in age-adjusted terms. The gap between recent advances and the growing worldwide mortality appears to result from sequential roadblocks that limit the flow from basic research to clinical development (translational research type 1, T1), from clinical development to clinical practice (translational research T2) and result in deficient widespread worldwide implementation of already available medical advances (translational research T3). We now review recent advances and novel concepts that have the potential to change the practice of nephrology in order to improve the outcomes of the maximal number of individuals in the shortest possible interval. These include: (i) updating the CKD concept, shifting the emphasis to the identification, risk stratification and care of early CKD and redefining the concept of aging-associated 'physiological' decline of renal function; (ii) advances in the characterization of aetiological factors, including challenging the concept of hypertensive nephropathy, the better definition of the genetic contribution to CKD progression, assessing the role of the liquid biopsy in aetiological diagnosis and characterizing the role of drugs that may be applied to the earliest stages of injury, such as SGLT2 inhibitors in diabetic kidney disease (DKD); (iii) embracing the complexity of CKD as a network disease and (iv) exploring ways to optimize implementation of existing knowledge.

Abstract
We summarize new knowledge that has accrued in recent years on chronic kidney disease (CKD) in Indigenous Australians. CKD refers to all stages of preterminal kidney disease, including end‐stage kidney failure (ESKF), whether or not a person receives renal replacement therapy (RRT). Recently recorded rates of ESKF, RRT, non‐dialysis CKD hospitalizations and CKD attributed deaths were, respectively, more than sixfold, eightfold, eightfold and threefold those of non‐Indigenous Australians, with age adjustment, although all except the RRT rates are still under‐enumerated. However, the nationwide average Indigenous incidence rate of RRT appears to have stabilized. The median age of Indigenous people with ESKF was about 30 years less than for non‐Indigenous people, and 84% of them received RTT, while only half of non‐Indigenous people with ESKF did so. The first‐ever (2012) nationwide health survey data showed elevated levels of CKD markers in Indigenous people at the community level. For all CKD parameters, rates among Indigenous people themselves were strikingly correlated with increasing remoteness of residence and socio‐economic disadvantage, and there was a female predominance in remote areas. The burden of renal disease in Australian Indigenous people is seriously understated by Global Burden of Disease Mortality methodology, because it employs underlying cause of death only, and because deaths of people on RRT are frequently attributed to non‐renal causes. These data give a much expanded view of CKD in Aboriginal people. Methodologic approaches must be remedied for a full appreciation of the burden, costs and outcomes of the disease, to direct appropriate policy development. Excellent review on the kidney health in the Aboriginal communities in Australia, describing the challenges and important priorities.

Abstract
In this issue of CKJ, McQuarrie et al. have explored the relationship between socioeconomic status and outcomes among Scottish patients with a renal biopsy diagnosis of primary glomerulonephritis. Patients in the lower socioeconomic category had a twofold higher risk of death. No significant differences were observed on progression to end-stage renal disease (ESRD) requiring renal replacement therapy (RRT), suggesting that overall medical management was appropriate for all socioeconomic categories. The findings are significant since they come from an ethnically homogeneous population with free access to healthcare; they also relate to a specific aetiology of chronic kidney disease (CKD) expected to be less dependent on unhealthy lifestyles than other more frequent aetiologies that dominate studies of CKD in general, such as diabetic or hypertensive nephropathy. A closer look at the data suggests that living in a high socioeconomic area is associated with lower mortality, rather than the other way round. Furthermore, the differences in mortality were most pronounced during the RRT stage of CKD, providing clues for further research. In this regard, Wilmink et al. and Nee et al. point to access to pre-ESRD nephrology care and to the best kidney transplantation options as modifiable factors to be studied in the realm of T3 translational research to improve CKD patient outcomes.

Abstract
Climate change has led to significant rise of 0.8°C-0.9°C in global mean temperature over the last century and has been linked with significant increases in the frequency and severity of heat waves (extreme heat events). Climate change has also been increasingly connected to detrimental human health. One of the consequences of climate-related extreme heat exposure is dehydration and volume loss, leading to acute mortality from exacerbations of pre-existing chronic disease, as well as from outright heat exhaustion and heat stroke. Recent studies have also shown that recurrent heat exposure with physical exertion and inadequate hydration can lead to CKD that is distinct from that caused by diabetes, hypertension, or GN. Epidemics of CKD consistent with heat stress nephropathy are now occurring across the world. Here, we describe this disease, discuss the locations where it appears to be manifesting, link it with increasing temperatures, and discuss ongoing attempts to prevent the disease. Heat stress nephropathy may represent one of the first epidemics due to global warming. Government, industry, and health policy makers in the impacted regions should place greater emphasis on occupational and community interventions.

Abstract
In chronic kidney disease inflammatory processes and stimulation of immune cells result in overproduction of free radicals. In combination with a reduced antioxidant capacity this causes oxidative stress. This review focuses on current pathogenic concepts of oxidative stress for the decline of kidney function and development of cardiovascular complications. We discuss the impact of mitochondrial alterations and dysfunction, a pathogenic role for hyperuricemia, and disturbances of vitamin D metabolism and signal transduction. Recent antioxidant therapy options including the use of vitamin D and pharmacologic therapies for hyperuricemia are discussed. Finally, we review some new therapy options in diabetic nephropathy including antidiabetic agents (noninsulin dependent), plant antioxidants, and food components as alternative antioxidant therapies.

Abstract
The aim of the present study was to investigate the effect of Yi Qi Qing Re Gao-containing serum (YQ-S) on rat mesangial cell (MC) proliferation and to investigate the underlying mechanism. MCs were divided into the control, lipopolysaccharide (LPS)-stimulated, YQ-S and fosinopril-containing serum (For-S) groups, and cultured for 48 h. An MTT assay was used to evaluate the proliferation of MCs. In addition, reverse transcription-quantitative polymerase chain reaction and western blot analysis were conducted to detect the expression levels of Wnt4, β-catenin and transforming growth factor (TGF)-β1 in MCs. The results indicated that YQ-S inhibited LPS-induced MC proliferation. The Wnt4 and TGF-β1 mRNA expression levels were reduced in the YQ-S group (P<0.01 or P<0.05). Furthermore, the Wnt4, β-catenin and TGF-β1 protein expression levels were suppressed in the YQ-S group (P<0.01 or P<0.05). Therefore, YQ-S appears to inhibit MC proliferation, and its mechanism may involve the inhibition of the Wnt signaling pathway and downregulation of TGF-β1 expression.

Abstract
BACKGROUND AND OBJECTIVES Epidemics of CKD of uncertain etiology (CKDu) are emerging around the world. Highlighting common risk factors for CKD of uncertain etiology across various regions and populations may be important for health policy and public health responses. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We searched PubMed, Embase, Scopus and Web of Science databases to identify published studies on CKDu. The search was generated in January of 2015; no language or date limits were used. We used a vote-counting method to evaluate exposures across all studies. RESULTS We identified 1607 articles, of which 26 met inclusion criteria. Eighteen (69%) were conducted in known CKDu-endemic countries: Sri Lanka (38%), Nicaragua (19%), and El Salvador (12%). The other studies were from India, Japan, Australia, Mexico, Sweden, Tunisia, Tanzania, and the United States. Heavy metals, heat stress, and dietary exposures were reported across all geographic regions. In south Asia, family history, agrochemical use, and heavy metal exposures were reported most frequently, whereas altitude and temperature were reported only in studies from Central America. Across all regions, CKDu was most frequently associated with a family history of CKDu, agricultural occupation, men, middle age, snake bite, and heavy metal exposure. CONCLUSIONS Studies examining etiologies of CKDu have reported many exposures that are heterogeneous and vary by region. To identify etiologies of CKDu, designing consistent and comparative multisite studies across high-risk populations may help elucidate the importance of region-specific versus global risk factors.

Abstract
The ultimate aim of biomedical research is to preserve health and improve patient outcomes. However, by a variety of measures, preservation of kidney health and patient outcomes in kidney disease are suboptimal. Severe acute kidney injury has been treated solely by renal replacement therapy for over 50 years and mortality still hovers at around 50%. Worldwide deaths from chronic kidney disease (CKD) increased by 80% in 20 years--one of the greatest increases among major causes of death. This dramatic data concur with huge advances in the cellular and molecular pathophysiology of kidney disease and its consequences. The gap appears to be the result of sequential roadblocks that impede an adequate flow from basic research to clinical development [translational research type 1 (T1), bench-to-bed and back] and from clinical development to clinical practice and widespread implementation (translational research T2) that supported by healthcare policy-making reaches all levels of society throughout the globe (sometimes called translational research T3). Thus, it is more than 10 years since the introduction of the last new-concept drug for CKD patients, cinacalcet; and 30 years since the introduction of reninangiotensin system (RAS) blockade, the current mainstay to prevent progression of CKD, illustrating the basic science-clinical practice disconnect. Roadblocks from clinical advances to widespread implementation, together with lag time-to-benefit may underlie the 20 years since the description of the antiproteinuric effect of RAS blockade to the observation of decreased age-adjusted incidence of endstage renal disease due to diabetic kidney disease. Only a correct understanding of the roadblocks in translational medicine and a full embracement of a translational research culture will spread the benefits of the biomedical revolution to its ultimate destinatary, the society.
