Global variations in funding and use of hemodialysis accesses: an international report using the ISN Global Kidney Health Atlas.

BACKGROUND: There is a lack of contemporary data describing global variations in vascular access for hemodialysis (HD). We used the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) to highlight differences in funding and availability of hemodialysis accesses used for initiating HD across world regions. METHODS: Survey questions were directed at understanding the funding modules for obtaining vascular access and types of accesses used to initiate dialysis. An electronic survey was sent to national and regional key stakeholders affiliated with the ISN between June and September 2022. Countries that participated in the survey were categorized based on World Bank Income Classification (low-, lower-middle, upper-middle, and high-income) and by their regional affiliation with the ISN. RESULTS: Data on types of vascular access were available from 160 countries. Respondents from 35 countries (22% of surveyed countries) reported that > 50% of patients started HD with an arteriovenous fistula or graft (AVF or AVG). These rates were higher in Western Europe (n = 14; 64%), North & East Asia (n = 4; 67%), and among high-income countries (n = 24; 38%). The rates of > 50% of patients starting HD with a tunneled dialysis catheter were highest in North America & Caribbean region (n = 7; 58%) and lowest in South Asia and Newly Independent States and Russia (n = 0 in both regions). Respondents from 50% (n = 9) of low-income countries reported that > 75% of patients started HD using a temporary catheter, with the highest rates in Africa (n = 30; 75%) and Latin America (n = 14; 67%). Funding for the creation of vascular access was often through public funding and free at the point of delivery in high-income countries (n = 42; 67% for AVF/AVG, n = 44; 70% for central venous catheters). In low-income countries, private and out of pocket funding was reported as being more common (n = 8; 40% for AVF/AVG, n = 5; 25% for central venous catheters). CONCLUSIONS: High income countries exhibit variation in the use of AVF/AVG and tunneled catheters. In low-income countries, there is a higher use of temporary dialysis catheters and private funding models for access creation.

Long-term Health-related Quality of Life in Working-age COVID-19 Survivors: A Cross-sectional Study.

BACKGROUND: Most working-age (18-64) adults have been infected with SARS-CoV-2, and some may have developed post-COVID-19 condition (PCC). However, health-related quality of life (HRQOL) greater than 2 years following infection remains uncharacterized. METHODS: In this cross-sectional study, COVID-19 survivors from throughout British Columbia (BC), Canada, completed a questionnaire greater than 2 years post-infection. PCC status was self-reported, and HRQOL was assessed using the EuroQol 5-dimension 5-level (EQ-5D-5L) instrument. We compared HRQOL in those with current PCC, those with recovered PCC, and those without a history of PCC. Iterative proportional fitting was used to weight analyses to be representative of COVID-19 survivors in BC. Multivariable regression models were used to adjust for confounders. RESULTS: Of the 1,135 analyzed participants, 19.2% had current PCC, and 27.6% had recovered PCC. Compared to those without a history of PCC, participants with recovered PCC had a similar weighted mean EQ-5D health utility (adjusted difference -0.02 [95%CI -0.03, 0.00]), but those with current PCC had a lower health utility (adjusted difference -0.08 [95%CI -0.12, -0.05]). Compared to those without a history of PCC, participants with current PCC were more likely to report problems with mobility (adjusted odds ratio (aOR) 6.00 [95%CI 2.88-12.52]), self-care (aOR 5.96 [95%CI 1.84-19.32]), usual activities (aOR 8.00 [95%CI 4.27-14.99]), pain/discomfort (aOR 4.28 [95%CI 2.46-7.48]), and anxiety/depression (aOR 3.45 [95%CI 1.90-6.27]). CONCLUSIONS: In working-age adults who have survived greater than 2 years following COVID-19, HRQOL is high among those who have never had PCC or have recovered from PCC. However, individuals with ongoing symptoms of PCC have lower HRQOL and are more likely to have deficits in multiple functional domains. These findings underscore the importance of implementing targeted healthcare interventions to improve HRQOL in adults with long-term PCC.

IL-6 inhibition with clazakizumab in patients receiving maintenance dialysis: a randomized phase 2b trial.

Inflammation mediated by interleukin-6 (IL-6) is strongly associated with cardiovascular risk. Here we evaluated clazakizumab, a monoclonal antibody targeting the IL-6 ligand, in a phase 2b dose-finding study. Adults with cardiovascular disease and/or diabetes receiving maintenance dialysis with high-sensitivity C-reactive protein (hs-CRP) ≥ 2 mg l-1 at baseline were randomized to receive clazakizumab (2.5 mg, 5 mg or 10 mg, n = 32 per dose group) or placebo (n = 31) every 4 weeks. The primary endpoint was the change from baseline in hs-CRP to week 12, expressed as the geometric mean ratio. Clazakizumab treatment signficantly reduced serum hs-CRP concentrations at week 12 by 86%, 90% and 92% relative to placebo in patients randomized to 2.5 mg, 5 mg or 10 mg clazakizumab, respectively (all P < 0.0001), meeting the primary outcome. With regard to secondary endpoints, clazakizumab treatment reduced serum fibrinogen, amyloid A, secretory phospholipase A2, and lipoprotein(a) concentrations, as well as increased mean serum albumin concentrations at 12 weeks, relative to placebo. The proportion of patients who achieved hs-CRP < 2.0 mg l-1 was 79%, 82% and 79% in the 2.5 mg, 5 mg and 10 mg clazakizumab groups, respectively, compared with 0% of placebo-treated patients. With regard to safety, no cases of sustained grade 3 or 4 thrombocytopenia or neutropenia were observed. Serious infections were seen with similar frequency in the placebo, clazakizumab 2.5 mg and clazakizumab 5 mg groups, but were numerically more frequent in the clazakizumab 10 mg group. The results of this trial indicate that in patients receiving maintenance dialysis, clazakizumab reduced inflammatory biomarkers associated with cardiovascular events.

Implications of Implementing the 2021 CKD-EPI Equation Without Race on Managing Patients With Kidney Disease in British Columbia, Canada.

Introduction: We investigated the implications of implementing race-free Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) 2021 equation among real-world patients with chronic kidney disease (CKD) from British Columbia (BC), Canada. Methods: This study included nondialysis-dependent patients with CKD aged ≥19 years who were registered in the Patient Records and Outcome Management Information System (PROMIS) as of March 31, 2016 (index date) with ≥1 serum creatinine measurement within 1 year before the index date. Patients with a history of kidney transplantation before the index date were excluded. CKD-EPI 2021 versus 2009 equation was the exposure variable. Difference in mean estimated glomerular filtration rate (eGFR) and number (%) of patients reclassified to a different eGFR category were estimated. We used Fine and Gray subdistribution hazard model to investigate the association between change in eGFR category and progression to kidney failure (incident maintenance dialysis or kidney transplantation) within 2 years. Results: A total of 11,604 patients (median age 73 years, 52% male) were included. Compared to the 2009 equation, eGFR from 2021 equation was on average 2.7 ml/min per 1.73 m2 higher. Variation was higher among males. Overall, ∼17% of the study sample were reclassified to a category with higher eGFR by 2021 equation (switchers). The highest proportion (28%) of patients were reclassified from G5 to G4. The risk of progressing to kidney failure was 22% less among switchers compared to nonswitchers; adjusted subdistribution hazard ratio (HR) (95% confidence interval [CI]) is 0.78 (0.65, 0.94). Conclusion: CKD-EPI 2021 equation appeared to provide higher eGFR compared to 2009 equation. This higher eGFR values appeared to be concordant with subsequent real-world CKD progression outcomes. Higher eGFR from the 2021 equation may have substantial clinical implications in both diagnosis as well as long-term care of patients with CKD.

Organization and Structures for Detection and Monitoring of CKD Across World Countries and Regions: Observational Data From a Global Survey.

RATIONALE & OBJECTIVE: Established therapeutic interventions effectively mitigate the risk and progression of chronic kidney disease (CKD). Countries and regions have a compelling need for organizational structures that enable early identification of people with CKD who can benefit from these proven interventions. We aimed to report the current global status of CKD detection programs. STUDY DESIGN: A multinational cross-sectional survey. SETTING & PARTICIPANTS: Stakeholders, including nephrologist leaders, policymakers, and patient advocates from 167 countries, participating in the International Society of Nephrology (ISN) survey from June to September 2022. OUTCOMES: Structures for the detection and monitoring of CKD, including CKD surveillance systems in the form of registries, community-based detection programs, case-finding practices, and availability of measurement tools for risk identification. ANALYTICAL APPROACH: Descriptive statistics. RESULTS: Of all participating countries, 19% (n=31) reported CKD registries and 25% (n=40) reported implementing CKD detection programs as part of their national policies. There were variations in CKD detection program, with 50% (n=20) using a reactive approach (managing cases as identified) and 50% (n=20) actively pursuing case-finding in at-risk populations. Routine case-finding for CKD in high-risk populations was widespread, particularly for diabetes (n=152; 91%) and hypertension (n=148; 89%). Access to diagnostic tools, estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR), was limited, especially in low-income (LICs) and lower-middle-income (LMICs) countries, at primary (eGFR: LICs 22%, LMICs 39%, UACR: LICs 28%, LMICs 39%) and secondary/tertiary healthcare levels (eGFR: LICs 39%, LMICs 73%, UACR: LICs 44%, LMICs 70%), potentially hindering CKD detection. LIMITATIONS: A lack of detailed data prevented an in-depth analysis. CONCLUSION: This comprehensive survey highlights a global heterogeneity in the organization and structures (surveillance systems, detection programs and tools) for early identification of CKD. Ongoing efforts should be geared toward bridging such disparities to optimally prevent the onset and progression of CKD and its complications.

Pathways for Diagnosing and Treating CKD-Associated Pruritus: A Narrative Review.

Purpose of Review: Chronic kidney disease (CKD)-associated pruritus is a common, persistent, and distressing itch experienced by patients across the CKD spectrum. Although the disorder is associated with adverse outcomes and poor health-related quality of life, it remains underdiagnosed and undertreated. The purpose of this narrative review is to offer health care providers guidance on how to effectively identify, assess, and treat patients with CKD-associated pruritus, with the goal of reducing symptom burden and improving patient-important outcomes, such as quality of life (QoL). Sources of Information: A panel of nephrologists and researchers from across Canada and the United States was assembled to develop this narrative review based on the best available data, current treatment guidelines, and their clinical experiences. Methods: A panel of nephrologists who actively care for patients with pruritus receiving dialysis from across Canada was assembled. Two researchers from the United States were also included based on their expertise in the diagnosis and management of CKD-associated pruritus. Throughout Spring 2023, the panel met to discuss key topics in the identification, assessment, and management of CKD-associated pruritus. Panel members subsequently developed summaries of the pertinent information based on the best available data, current treatment guidelines, and added information on their own clinical experiences. In all cases, approval of the article was sought and achieved through discussion. Key Findings: This narrative review provides pragmatic guidance addressing: (1) methods for screening CKD-associated pruritus, (2) assessing severity, (3) management of CKD-associated pruritus, and (4) suggested areas for future research. The panel developed a 3-pillar framework for proactive assessment and severity scoring in CKD-aP: systematic screening for CKD-associated pruritus (pillar 1), assessment of pruritus intensity (pillar 2), and understanding the impact of CKD-associated pruritus on the patient's QoL (pillar 3). Management of CKD-associated pruritus can include ensuring optimization of dialysis adequacy, achieving mineral metabolism targets (ie, calcium, phosphate, and parathyroid hormone). However, treatment of CKD-associated pruritus usually requires additional interventions. Patients, regardless of CKD-associated pruritus severity, should be counseled on adequate skin hydration and other non-pharmacological strategies to reduce pruritus. Antihistamines should be avoided in favor of evidence-based treatments, such as difelikefalin and gabapentin. Limitations: A formal systematic review (SR) of the literature was not undertaken, although published SRs were reviewed. The possibility for bias based on the experts' own clinical experiences may have occurred. Key takeaways are based on the current available evidence, of which head-to-head clinical trials are lacking. Funding: This work was funded by an arm's length grant from Otsuka Canada Pharmaceutical Inc. (the importer and distributer of difelikefalin in Canada). LiV Medical Education Agency Inc. provided logistical and editorial support.

Motif de la revue: Le prurit associé à l'insuffisance rénale chronique (IRC) est une démangeaison cutanée fréquente, persistante et invalidante que les patients de tout le specter de l'IRC peuvent ressentir. Bien que le prurit soit associé à des effets indésirables et à une mauvaise qualité de vie liée à la santé, il demeure sous-diagnostiqué et sous-traité. L'objectif de cette revue narrative est d'offrir des conseils aux professionnels de la santé sur la façon d'identifier, d'évaluer et de traiter efficacement les patients atteints de prurit associé à l'IRC; ceci dans le but de réduire la charge des symptômes et d'améliorer les résultats importants pour les patients, notamment leur qualité de vie (QdV). Sources de l'information: Un comité de néphrologues et de chercheurs de partout au Canada et des États-Unis a été constitué pour élaborer la présente revue narrative à partir des meilleures données disponibles, des lignes directrices actuelles pour le traitement et de leurs expériences cliniques. Méthodologie: Un groupe de néphrologues canadiens qui s'occupent activement de patients dialysés souffrant de prurit a été constitué. Deux chercheurs des États-Unis ont été inclus au groupe en raison de leur expertise dans le diagnostic et la prise en charge du prurit associé à l'IRC. Le comité s'est réuni tout au long du printemps 2023 pour discuter de sujets clés en lien avec l'identification, l'évaluation et la prise en charge du prurit associé à l'IRC. Les membres du comité ont par la suite rédigé des résumés des informations pertinentes en se basant sur les meilleures données disponibles et les lignes directrices actuelles pour le traitement, auxquels ils ont ajouté des informations issues de leurs propres expériences cliniques. Dans tous les cas, l'approbation du manuscrit a été sollicitée et obtenue par discussion. Principaux résultats: Cette revue narrative offre des conseils pragmatiques sur les points suivants: (1) les méthodes de dépistage du prurit associé à l'IRC; (2) l'évaluation de sa gravité; (3) sa prise en charge; et (4) les domaines suggérés pour de futures recherches. Le comité a développé un cadre à trois piliers pour l'évaluation proactive du prurit associé à l'IRC et l'établissement d'un score de gravité: le dépistage systématique du prurit associé à l'IRC (pilier 1), l'évaluation de son intensité (pilier 2) et la compréhension de son impact sur la QdV du patient (pilier 3). La prise en charge du prurit associé à l'IRC peut inclure l'optimisation de l'adéquation de la dialyse et l'atteinte des cibles du métabolisme minéral (c.-à-d. calcium, phosphate et hormone parathyroïdienne). Cependant, son traitement nécessite habituellement des interventions supplémentaires. Les patients, quelle que soit la gravité du prurit associé à l'IRC, devraient être avisés d'hydrater adéquatement leur peau et informés des autres stratégies non pharmacologiques afin de réduire le prurit. On devrait éviter les antihistaminiques et les remplacer par des traitements fondés sur des données probantes comme la difélikéfaline et la gabapentine. Limites: Aucune revue systématique de la littérature n'a été formellement entreprise, bien que les revues systématiques publiées aient été examinées. La possibilité d'un biais fondé sur les expériences cliniques des experts est envisageable. Les principales conclusions de cette étude sont fondées sur les données probantes actuellement disponibles, pour lesquelles il n'existe pas d'essais cliniques comparatifs. Financement: Ces travaux ont été financés par une subvention indépendante d'Otsuka Canada Pharmaceutical Inc. (l'importateur et distributeur de la difélikéfaline au Canada).

Perceptions and Information-Seeking Behavior Regarding COVID-19 Vaccination Among Patients With Chronic Kidney Disease in 2023: A Cross-Sectional Survey.

Background: People living with chronic kidney disease (CKD) face an increased risk of severe outcomes such as hospitalization or death from COVID-19. COVID-19 vaccination is a vital approach to mitigate the risk and severity of infection in patients with CKD. Limited information exists regarding the factors that shape COVID-19 vaccine uptake, including health information-seeking behavior and perceptions, within the CKD population. Objective: The objectives were to describe among CKD patients, (1) health information-seeking behavior on COVID-19, (2) their capacity to comprehend and trust COVID-19 information from different sources, and (3) their perceptions concerning COVID-19 infection and vaccination. Design/Setting: Cross-sectional web-based survey administered in British Columbia and Ontario from February 17, 2023, to April 17, 2023. Participants: Chronic kidney disease G3b-5D patients and kidney transplant recipients (CKD G1T-5T) enrolled in a longitudinal COVID-19 vaccine serology study. Methods and Measurements: The survey consisted of a questionnaire that included demographic and clinical data, perceived susceptibility of contracting COVID-19, the ability to collect, understand, and trust information on COVID-19, as well as perceptions regarding COVID-19 vaccination. Descriptive statistics were used to present the data with values expressed as count (%) and chi square tests were performed with a significance level set at P ≤ .05. A content analysis was performed on one open-ended response regarding respondents' questions surrounding COVID-19 infection and vaccination. Results: Among the 902 patients who received the survey via email, 201 completed the survey, resulting in a response rate of 22%. The median age was 64 years old (IQR 53-74), 48% were male, 51% were university educated, 32% were on kidney replacement therapies, and 57% had received ≥5 COVID-19 vaccine doses. 65% of respondents reported that they had sought out COVID-19-related information in the last 12 months, with 91% and 84% expressing having understood and trusted the information they received, respectively. Those with a higher number of COVID-19 vaccine doses were associated with having sought out (P =.017), comprehended (P < .001), and trusted (P =. 005) COVID-19-related information. Female sex was associated with expressing more concern about contracting COVID-19 (P = .011). Most respondents strongly agreed to statements regarding the benefits of COVID-19 vaccination. Respondents' questions about COVID-19 infection and vaccination centered on 4 major themes: COVID-19 vaccination strategy, vaccine effectiveness, vaccine safety, and the impact of COVID-19 infection and vaccination on kidney health. Limitations: This survey was administered within the Canadian health care context to patients with CKD who had at least 1 COVID-19 vaccine dose. Race/ethnicity of participants was not captured. Conclusions: In this survey of individuals with CKD, COVID-19 information-seeking behavior was high and almost all respondents understood and trusted the information they received. Perceptions toward the COVID-19 vaccine and booster were mostly favorable.

Capacity for the management of kidney failure in the International Society of Nephrology Africa region: report from the 2023 ISN Global Kidney Atlas (ISN-GKHA).

The burden of chronic kidney disease and associated risk of kidney failure are increasing in Africa. The management of people with chronic kidney disease is fraught with numerous challenges because of limitations in health systems and infrastructures for care delivery. From the third iteration of the International Society of Nephrology Global Kidney Health Atlas, we describe the status of kidney care in the ISN Africa region using the World Health Organization building blocks for health systems. We identified limited government health spending, which in turn led to increased out-of-pocket costs for people with kidney disease at the point of service delivery. The health care workforce across Africa was suboptimal and further challenged by the exodus of trained health care workers out of the continent. Medical products, technologies, and services for the management of people with nondialysis chronic kidney disease and for kidney replacement therapy were scarce due to limitations in health infrastructure, which was inequitably distributed. There were few kidney registries and advocacy groups championing kidney disease management in Africa compared with the rest of the world. Strategies for ensuring improved kidney care in Africa include focusing on chronic kidney disease prevention and early detection, improving the effectiveness of the available health care workforce (e.g., multidisciplinary teams, task substitution, and telemedicine), augmenting kidney care financing, providing quality, up-to-date health information data, and improving the accessibility, affordability, and delivery of quality treatment (kidney replacement therapy or conservative kidney management) for all people living with kidney failure.

Capacity for the management of kidney failure in the International Society of Nephrology North and East Asia region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

Globally, there remain significant disparities in the capacity and quality of kidney care, as evidenced by the third edition of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA). In the ISN North and East Asia region, the chronic kidney disease (CKD) burden varied widely; Taiwan had the heaviest burden of treated kidney failure (3679 per million population [pmp]) followed by Japan and South Korea. Except in Hong Kong, hemodialysis (HD) was the main dialysis modality for all other countries in the region and was much higher than the global median prevalence. Kidney transplantation services were generally available in the region, but the prevalence was much lower than that of dialysis. Most countries had public funding for kidney replacement therapy (KRT). The median prevalence of nephrologists was 28.7 pmp, higher than that of any other ISN region, with variation across countries. Home HD was available in only 17% of the countries, whereas conservative kidney management was available in 50%. All countries had official registries for dialysis and transplantation; however, only China and Japan had CKD registries. Advocacy groups for CKD, kidney failure, and KRT were uncommon throughout the region. Overall, all countries in the region had capacity for KRT, albeit with some shortages in their kidney care workforce. These data are useful for stakeholders to address gaps in kidney care and to reduce workforce shortages through increased use of multidisciplinary teams and telemedicine, policy changes to promote prevention and treatment of kidney failure, and increased advocacy for kidney disease in the region.

Capacity for the management of kidney failure in the International Society of Nephrology Newly Independent States and Russia region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

The International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) was established to aid understanding of the status and capacity of countries to provide optimal kidney care worldwide. This report presents the current characteristics of kidney care in the ISN Newly Independent States (NIS) and Russia region. Although the median prevalence of chronic kidney disease (CKD) was higher (11.4%) than the global median (9.5%), the median CKD-related death rate (1.4%) and prevalence of treated kidney failure (KF) in the region (411 per million population [pmp]) were lower than they are globally (2.5% and 822.8 pmp, respectively). Capacity to provide an adequate frequency of hemodialysis (HD) and kidney transplantation services is present in all the countries (100%). In spite of significant economic advancement, the region has critical shortages of nephrologists, dietitians, transplant coordinators, social workers, palliative care physicians, and kidney supportive care nurses. Home HD remains unavailable in any country in the region. Although national registries for dialysis and kidney transplantation are available in most of the countries across the ISN NIS and Russia region, few registries exist for nondialysis CKD and acute kidney injury. Although a national strategy for improving care for CKD patients is presented in more than half of the countries, no country in the region had a CKD-specific policy. Strategies that incorporate workforce training, planning, and development for all KF caregivers could help ensure sustainable kidney care delivery in the ISN NIS and Russia region.

Capacity for the management of kidney failure in the International Society of Nephrology North America and the Caribbean region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

The International Society of Nephrology Global Kidney Health Atlas charts the availability and capacity of kidney care globally. In the North America and the Caribbean region, the Atlas can identify opportunities for kidney care improvement, particularly in Caribbean countries where structures for systematic data collection are lacking. In this third iteration, respondents from 12 of 18 countries from the region reported a 2-fold higher than global median prevalence of dialysis and transplantation, and a 3-fold higher than global median prevalence of dialysis centers. The peritoneal dialysis prevalence was lower than the global median, and transplantation data were missing from 6 of the 10 Caribbean countries. Government-funded payments predominated for dialysis modalities, with greater heterogeneity in transplantation payor mix. Services for chronic kidney disease, such as monitoring of anemia and blood pressure, and diagnostic capability relying on serum creatinine and urinalyses were universally available. Notable exceptions in Caribbean countries included non-calcium-based phosphate binders and kidney biopsy services. Personnel shortages were reported across the region. Kidney failure was identified as a governmental priority more commonly than was chronic kidney disease or acute kidney injury. In this generally affluent region, patients have better access to kidney replacement therapy and chronic kidney disease-related services than in much of the world. Yet clear heterogeneity exists, especially among the Caribbean countries struggling with dialysis and personnel capacity. Important steps to improve kidney care in the region include increased emphasis on preventive care, a focus on home-based modalities and transplantation, and solutions to train and retain specialized allied health professionals.

Capacity for the management of kidney failure in the International Society of Nephrology Oceania and South East Asia (OSEA) region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

The International Society of Nephrology (ISN) region of Oceania and South East Asia (OSEA) is a mix of high- and low-income countries, with diversity in population demographics and densities. Three iterations of the ISN-Global Kidney Health Atlas (GKHA) have been conducted, aiming to deliver in-depth assessments of global kidney care across the spectrum from early detection of CKD to treatment of kidney failure. This paper reports the findings of the latest ISN-GKHA in relation to kidney-care capacity in the OSEA region. Among the 30 countries and territories in OSEA, 19 (63%) participated in the ISN-GKHA, representing over 97% of the region's population. The overall prevalence of treated kidney failure in the OSEA region was 1203 per million population (pmp), 45% higher than the global median of 823 pmp. In contrast, kidney replacement therapy (KRT) in the OSEA region was less available than the global median (chronic hemodialysis, 89% OSEA region vs. 98% globally; peritoneal dialysis, 72% vs. 79%; kidney transplantation, 61% vs. 70%). Only 56% of countries could provide access to dialysis to at least half of people with incident kidney failure, lower than the global median of 74% of countries with available dialysis services. Inequalities in access to KRT were present across the OSEA region, with widespread availability and low out-of-pocket costs in high-income countries and limited availability, often coupled with large out-of-pocket costs, in middle- and low-income countries. Workforce limitations were observed across the OSEA region, especially in lower-middle-income countries. Extensive collaborative work within the OSEA region and globally will help close the noted gaps in kidney-care provision.

Capacity for the management of kidney failure in the International Society of Nephrology Middle East region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

The highest financial and symptom burdens and the lowest health-related quality-of-life scores are seen in people with kidney failure. A total of 11 countries in the International Society of Nephrology (ISN) Middle East region responded to the ISN-Global Kidney Health Atlas. The prevalence of chronic kidney disease (CKD) in the region ranged from 4.9% in Yemen to 12.2% in Lebanon, whereas prevalence of kidney failure treated with dialysis or transplantation ranged from 152 per million population (pmp) in the United Arab Emirates to 869 pmp in Kuwait. Overall, the incidence of kidney transplantation was highest in Saudi Arabia (20.2 pmp) and was lowest in Oman (2.2 pmp). Chronic hemodialysis (HD) and peritoneal dialysis (PD) services were available in all countries, whereas kidney transplantation was available in most countries of the region. Public government funding that makes acute dialysis, chronic HD, chronic PD, and kidney transplantation medications free at the point of delivery was available in 54.5%, 72.7%, 54.5%, and 54.5% of countries, respectively. Conservative kidney management was available in 45% of countries. Only Oman had a CKD registry; 7 countries (64%) had dialysis registries, and 8 (73%) had kidney transplantation registries. The ISN Middle East region has a high burden of kidney disease and multiple challenges to overcome. Prevention and detection of kidney disease can be improved by the design of tailored guidelines, allocation of additional resources, improvement of early detection at all levels of care, and implementation of sustainable health information systems.

Capacity for the management of kidney failure in the International Society of Nephrology Latin America region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

Successful management of chronic kidney disease (CKD) in Latin America (LA) continues to represent a challenge due to high disease burden and geographic disparities and difficulties in terms of capacity, accessibility, equity, and quality of kidney failure care. Although LA has experienced significant social and economic progress over the past decades, there are still important inequities in health care access. Through this third iteration of the International Society of Nephrology Global Kidney Health Atlas, the indicators regarding kidney failure care in LA are updated. Survey responses were received from 22 of 31 (71%) countries in LA representing 96.5% of its total population. Median CKD prevalence was 10.2% (interquartile range: 8.4%-12.3%), median CKD disability-adjusted life year was 753.4 days (interquartile range: 581.3-1072.5 days), and median CKD mortality was 5.5% (interquartile range: 3.2%-6.3%). Regarding dialysis modality, hemodialysis continued to be the most used therapy, whereas peritoneal dialysis reached a plateau and kidney transplantation increased steadily over the past 10 years. In 20 (91%) countries, >50% of people with kidney failure could access dialysis, and in only 2 (9%) countries, people who had access to dialysis could initiate dialysis with peritoneal dialysis. A mix of public and private systems collectively funded most aspects of kidney replacement therapy (dialysis and transplantation) with many people incurring up to 50% of out-of-pocket costs. Few LA countries had CKD/kidney replacement therapy registries, and almost no acute kidney injury registries were reported. There was large variability in the nature and extent of kidney failure care in LA mainly related to countries' funding structures and limited surveillance and management initiatives.

Capacity for the management of kidney failure in the International Society of Nephrology Western Europe region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

Western Europe boasts advanced health care systems, robust kidney care guidelines, and a well-established health care workforce. Despite this, significant disparities in kidney replacement therapy incidence, prevalence, and transplant access exist. This paper presents the third International Society of Nephrology Global Kidney Health Atlas's findings on kidney care availability, accessibility, affordability, and quality in 22 Western European countries, representing 99% of the region's population. The known chronic kidney disease (CKD) prevalence across Western Europe averages 10.6%, slightly above the global median. Cardiovascular diseases account for a substantial portion of CKD-related deaths. Kidney failure incidence varies. Government health expenditure differs; however, most countries offer government-funded acute kidney injury, dialysis, and kidney transplantation care. Hemodialysis and peritoneal dialysis are universally available, with variations in the number of dialysis centers. Kidney transplantation is available in all countries (except for 3 microstates), with variable transplant center prevalence. Conservative kidney management (CKM) is increasingly accessible. The region's kidney care workforce is substantial, exceeding global averages; however, workforce shortages are reported. Barriers to optimal kidney care include limited workforce capacity, lack of surveillance mechanisms, and suboptimal integration into national noncommunicable disease (NCD) strategies. Policy recognition of CKD as a health priority varies across countries. Although Western Europe exhibits strong kidney care infrastructure, opportunities for improvement exist, particularly in CKD prevention, surveillance, awareness, and policy implementation. Efforts to improve CKD care should include automated detection, educational support, and enhanced workflows. Based on these findings, health care professionals, stakeholders, and policymakers are called to act to enhance kidney care across the region.

Capacity for the management of kidney failure in the International Society of Nephrology Eastern and Central Europe region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

Delivery of care for kidney failure (KF) globally has a significant disparity; even in some countries, it means end of life for the person. The International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) tries to address gaps in KF care and standardize global nephrology care. From the third iteration of the ISN-GKHA, we present data for countries in the ISN Eastern and Central Europe region. The median prevalences of chronic kidney disease (12.8%) and treated KF (873.5 pmp) were higher than the global rates, respectively. Hemodialysis was the most preferred modality for KF in adults, whereas kidney replacement therapy was more balanced in children. Although most of the countries in the region had lower-middle-income and upper-middle-income levels, health expenditures for kidney health care were almost generally covered publicly. Nephrologists were responsible for the medical kidney care of people with KF in all countries. There was adequate infrastructure to provide all kinds of treatment for kidney care in the region. Regional characteristics such as high levels of obesity, smoking, and Balkan nephropathy as an endemic disease coupled with a shortage of workforce and finance continued to affect kidney care in the region negatively. By making organizational and legislative arrangements, partnerships with national authorities and societies may accelerate the improvement of kidney health care in the region.

A new era in the science and care of kidney diseases.

Notable progress in basic, translational and clinical nephrology research has been made over the past five decades. Nonetheless, many challenges remain, including obstacles to the early detection of kidney disease, disparities in access to care and variability in responses to existing and emerging therapies. Innovations in drug development, research technologies, tissue engineering and regenerative medicine have the potential to improve patient outcomes. Exciting prospects include the availability of new drugs to slow or halt the progression of chronic kidney disease, the development of bioartificial kidneys that mimic healthy kidney functions, and tissue engineering techniques that could enable transplantable kidneys to be created from the cells of the recipient, removing the risk of rejection. Cell and gene therapies have the potential to be applied for kidney tissue regeneration and repair. In addition, about 30% of kidney disease cases are monogenic and could potentially be treated using these genetic medicine approaches. Systemic diseases that involve the kidney, such as diabetes mellitus and hypertension, might also be amenable to these treatments. Continued investment, communication, collaboration and translation of innovations are crucial to realize their full potential. In addition, increasing sophistication in exploring large datasets, implementation science, and qualitative methodologies will improve the ability to deliver transformational kidney health strategies.

Psychiatric Symptoms, Treatment Uptake, and Barriers to Mental Health Care Among US Adults With Post-COVID-19 Condition.

Importance: Psychiatric symptoms are reportedly common among adults with post-COVID-19 condition (PCC). However, nationally representative data regarding symptom prevalence, treatment uptake, and barriers to care are needed to inform the development of care models. Objectives: To evaluate the prevalence of psychiatric symptoms in US adults with PCC compared with those without PCC and assess treatment uptake and cost-related barriers to treatment. Design, Setting, and Participants: Data from the 2022 National Health Interview Survey (NHIS), a nationally representative US cross-sectional survey, were analyzed between October 2023 and February 2024. Exposure: Current PCC, defined as new symptoms following SARS-CoV-2 infection lasting more than 3 months and ongoing at the time of interview. Main Outcomes and Measures: Depression symptoms were evaluated by the Patient Health Questionnaire-8 and anxiety symptoms were assessed using the General Anxiety Disorder-7 instrument. Participants were classified as having received treatment if they received mental health counseling or therapy or medications for mental health. Sleep difficulties, cognitive difficulties, disabling fatigue, and cost-related barriers were assessed from additional NHIS questions. Results: Of the 25 122 participants representing approximately 231 million US adults (median [IQR] age, 46 [32-61] years; 49.8% male and 50.2% female participants), a weighted prevalence (wPr) of 3.4% (95% CI, 3.1%-3.6%) had current PCC. Compared with other US adults, participants with current PCC were more likely to have depression symptoms (wPr, 16.8% vs 7.1%; adjusted odds ratio [AOR], 1.96; 95% CI, 1.51-2.55), anxiety symptoms (wPr, 16.7% vs 6.3%; AOR, 2.21; 95% CI, 1.53-3.19), sleep difficulties (wPr, 41.5% vs 22.7%; AOR 1.95; 95% CI, 1.65-2.29), cognitive difficulties (wPr, 35.0% vs 19.5%; AOR, 2.04; 95% CI, 1.66-2.50), and disabling fatigue (wPr, 4.0% vs 1.6%; AOR, 1.85; 95% CI, 1.20-2.86). Among participants who had depression or anxiety symptoms, those with PCC had a similar likelihood of not having received treatment (wPr, 28.2% vs 34.9%; AOR, 1.02; 95% CI, 0.66-1.57). However, participants with current PCC were more likely to report a cost-related barrier to accessing mental health counseling or therapy (wPr, 37.2% vs 23.3%; AOR, 2.05; 95% CI, 1.40-2.98). Conclusions and Relevance: The findings of this study suggest that people with PCC have a higher prevalence of psychiatric symptoms than other adults but are more likely to experience cost-related barriers to accessing therapy. Care pathways for PCC should consider prioritizing mental health screening and affordable treatment.
