The South Asia region is facing a high burden of chronic kidney disease (CKD) with limited health resources and low expenditure on health care. In addition to the burden of CKD and kidney failure from traditional risk factors, CKD of unknown etiologies from India and Sri Lanka compounds the challenges of optimal management of CKD in the region. From the third edition of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA), we present the status of CKD burden, infrastructure, funding, resources, and health care personnel using the World Health Organizations building blocks for health systems in the ISN South Asia region. The poor status of the public health care system and low health care expenditure resulted in high out-of-pocket expenditures for people with kidney disease, which further compounded the situation. There is insufficient country capacity across the region to provide kidney replacement therapies to cover the burden. The infrastructure was also not uniformly distributed among the countries in the region. There were no chronic hemodialysis centers in Afghanistan, and peritoneal dialysis services were only available in Bangladesh, India, Nepal, Pakistan, and Sri Lanka. Kidney transplantation was not available in Afghanistan, Bhutan, and Maldives. Conservative kidney management was reported as available in 63% (n = 5) of the countries, yet no country reported availability of the core CKM care components. There was a high hospitalization rate and early mortality because of inadequate kidney care. The lack of national registries and actual disease burden estimates reported in the region prevent policymakers attention to CKD as an important cause of morbidity and mortality. Data from the 2023 ISN-GKHA, although with some limitations, may be used for advocacy and improving CKD care in the region.

Background: This systematic review aims to identify predictors of intradialytic hypotension (IDH) in critically ill patients undergoing kidney replacement therapy (KRT) for acute kidney injury (AKI). Methods: A comprehensive search of PubMed was conducted from 2002 to April 2024. Studies included critically ill adults undergoing KRT for AKI, excluding pediatric patients, non-critically ill individuals, those with chronic kidney disease, and those not undergoing KRT. The primary outcome was identifying predictive tools for hypotensive episodes during KRT sessions. Results: The review analyzed data from 8 studies involving 2873 patients. Various machine learning models were assessed for their predictive accuracy. The Extreme Gradient Boosting Machine (XGB) model was the top performer with an area under the receiver operating characteristic curve (AUROC) of 0.828 (95% CI 0.796–0.861), closely followed by the deep neural network (DNN) with an AUROC of 0.822 (95% CI 0.789–0.856). All machine learning models outperformed other predictors. The SOCRATE score, which includes cardiovascular SOFA score, index capillary refill, and lactate level, had an AUROC of 0.79 (95% CI 0.69–0.89, p < 0.0001). Peripheral perfusion index (PPI) and heart rate variability (HRV) showed AUROCs of 0.721 (95% CI 0.547–0.857) and 0.761 (95% CI 0.59–0.887), respectively. Pulmonary vascular permeability index (PVPI) and mechanical ventilation also demonstrated significant diagnostic performance. A PVPI ≥ 1.6 at the onset of intermittent hemodialysis (IHD) sessions predicted IDH associated with preload dependence with a sensitivity of 91% (95% CI 59–100%) and specificity of 53% (95% CI 42–63%). Conclusion: This systematic review shows how combining predictive models with clinical indicators can forecast IDH in critically ill AKI patients undergoing KRT, with validation in diverse settings needed to improve accuracy and patient care strategies.

Kidney diseases have become a global epidemic with significant public health impact. Chronic kidney disease (CKD) is set to become the fifth largest cause of death by 2040, with major impacts on low-resource countries. This review is based on a recent report of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) which uncovered gaps in key vehicles of kidney care delivery assessed using World Health Organization building blocks for health systems (financing, services delivery, workforce, access to essential medicines, health information systems and leadership/governance). High-income countries had more centres for kidney replacement therapies (KRT), higher KRT access, higher allocation of public funds to KRT, larger workforces, more health information systems, and higher government recognition of CKD and KRT as health priorities than low-income nations. Evidence identified from the current ISN-GKHA initiative should serve as template for generating and advancing policies and partnerships to address the global burden of kidney disease. The results provide opportunities for kidney health policymakers, nephrology leaders and organizations to initiate consultations to identify strategies for improving care delivery and access in equitable, resource-sensitive manners. Policies to increase use of public funding for kidney care, lower the cost of KRT and increase workforces should be a high priority in low-resource nations, while strategies that expand access to kidney care and maintain current status of care should be prioritized in high-income countries. In all countries, the perspectives of people with CKD should be exhaustively explored to identify core kidney care priorities. [ABSTRACT FROM AUTHOR]

An international multidisciplinary panel held a roundtable discussion on endovascular arteriovenous fistula (endoAVF) for vascular access (VA) for dialysis. The panel made literature- and experiencebased recommendations on best practice and opportunities for targeted use, covering the benefits of endoAVF; patient selection; institutional and pathway issues; patient education; and peer support.

Hemobiologic reactions associated with the hemoincompatibility of extracorporeal circuit material are an undesirable and inevitable consequence of all blood-contacting medical devices, typically considered only from a clinical perspective. In hemodialysis (HD), the blood of patients undergoes repetitive (at least thrice weekly for 4 h and lifelong) exposure to different polymeric materials that activate plasmatic pathways and blood cells. There is a general agreement that hemoincompatibility reactions, although unavoidable during extracorporeal therapies, are unphysiological contributors to non-hemodynamic dialysis-induced systemic stress and need to be curtailed. Strategies to lessen the periodic and direct effects of blood interacting with artificial surfaces to stimulate numerous biological pathways have focused mainly on the development of 'more passive' materials to decrease intradialytic morbidity. The indirect implications of this phenomenon, such as its impact on the overall delivery of care, have not been considered in detail. In this article, we explore, for the first time, the potential clinical and economic consequences of hemoincompatibility from a value-based healthcare (VBHC) perspective. As the fundamental tenet of VBHC is achieving the best clinical outcomes at the lowest cost, we examine the equation from the individual perspectives of the three key stakeholders of the dialysis care delivery processes: the patient, the provider, and the payer. For the patient, sub-optimal therapy caused by hemoincompatibility results in poor quality of life and various dialysis-associated conditions involving cost-impacting adjustments to lifestyles. For the provider, the decrease in income is attributed to factors such as an increase in workload and use of resources, dissatisfaction of the patient from the services provided, loss of reimbursement and direct revenue, or an increase in doctor–nurse turnover due to the complexity of managing care (nephrology encounters a chronic workforce shortage). The payer and healthcare system incur additional costs, e.g., increased hospitalization rates, including intensive care unit admissions, and increased medications and diagnostics to counteract adverse events and complications. Thus, hemoincompatibility reactions may be relevant from a socioeconomic perspective and may need to be addressed beyond just its clinical relevance to streamline the delivery of HD in terms of payability, future sustainability, and societal repercussions. Strategies to mitigate the economic impact and address the cost-effectiveness of the hemoincompatibility of extracorporeal kidney replacement therapy are proposed to conclude this comprehensive approach.

Background: Kidney replacement therapy (KRT) needs preparation and its timing is difficult to predict. Nephrologists' predictions of kidney failure risk tend to be more pessimistic than the Kidney Failure Risk Equation (KFRE) predictions. We aimed to explore how physicians' risk estimate related to referral to KRT education, vs. the objective calculated KFRE. Methods: Prospective observational study of data collected in chronic kidney disease (CKD) clinics of the Veterans Affairs Medical Center San Diego and the University of California, San Diego. The study included 257 participants who were aged 18 years or older, English speaking, prevalent CKD clinic patients, with estimated glomerular filtration rate (eGFR) < 60 mL/min per 1.73 m2 (MDRD equation). The exposure consisted of end stage kidney disease (ESKD) risk predictions. Nephrologists' kidney failure risk estimations were assessed: "On a scale of 0–100%, without using any estimating equations, give your best estimate of the risk that this patient will need dialysis or a kidney transplant in 2 years." KFRE was calculated using age, sex, eGFR, serum bicarbonate, albumin, calcium, phosphorus, urine albumin/creatinine ratio. The outcomes were the pattern of referral to KRT education (within 90 days of initial visit) and kidney failure evaluated by chart review. The population was divided into groups either by nephrologists' predictions or by KFRE. Referral to KRT education was examined by group and sensitivity and specificity were calculated based on whether participants reached kidney failure at 2 years. Results: A fifth were referred for education by 90 days of enrollment. Low risk patients by both estimates had low referral rates. In those with nephrologists' predictions ≥ 15% (n = 137), sensitivity was 71% and specificity 76%. In those with KFRE ≥ 15% (n = 55), sensitivity was 85% and specificity 41%. Conclusions: Although nephrologists tend to overestimate patients' kidney failure risk, they do not appear to act on this overestimation, as the rates of KRT education referrals are lower than expected when a nephrologist identifies a patient as high risk.

Background This paper compares the most recent data on the incidence and prevalence of kidney replacement therapy (KRT), kidney transplantation rates, and mortality on KRT from Europe to those from the United States (US), including comparisons of treatment modalities (haemodialysis (HD), peritoneal dialysis (PD), and kidney transplantation (KTx)). Methods Data were derived from the annual reports of the European Renal Association (ERA) Registry and the United States Renal Data System (USRDS). The European data include information from national and regional renal registries providing the ERA Registry with individual patient data. Additional analyses were performed to present results for all participating European countries together. Results In 2021, the KRT incidence in the US (409.7 per million population (pmp)) was almost 3-fold higher than in Europe (144.4 pmp). Despite the substantial difference in KRT incidence, approximately the same proportion of patients initiated HD (Europe: 82%, US: 84%), PD (14%; 13%, respectively), or underwent pre-emptive KTx (4%; 3%, respectively). The KRT prevalence in the US (2436.1 pmp) was 2-fold higher than in Europe (1187.8 pmp). Within Europe, approximately half of all prevalent patients were living with a functioning graft (47%), while in the US, this was one third (32%). The number of kidney transplantations performed was almost twice as high in the US (77.0 pmp) compared to Europe (41.6 pmp). The mortality of patients receiving KRT was 1.6-fold higher in the US (157.3 per 1000 patient years) compared to Europe (98.7 per 1000 patient years). Conclusions The US had a much higher KRT incidence, prevalence, and mortality compared to Europe, and despite a higher kidney transplantation rate, a lower proportion of prevalent patients with a functioning graft.

Background: Hypotension during dialysis arises from vasomotor tone alterations and hypovolemia, with disrupted counterregulatory mechanisms in acute kidney injury (AKI) patients. This study investigated the predictive value of preload dependency, assessed by the passive leg raising (PLR) test, and arterial tone, measured by dynamic elastance (Eadyn), for intradialytic hypotension (IDH). Methods: In this prospective observational study conducted in a tertiary hospital ICU, hemodynamic parameters were collected from critically ill AKI patients undergoing intermittent hemodialysis using the FloTrac/Vigileo system. Baseline measurements were recorded before KRT initiation, including the PLR test and Eadyn calculation. IDH was defined as mean arterial pressure (MAP) < 65 mmHg during dialysis. Logistic regression was used to identify predictors of IDH, and Kaplan–Meier analysis assessed 90-day survival. Results: Of 187 patients, 27.3% experienced IDH. Preload dependency, identified by positive PLR test, was significantly associated with IDH (OR 8.54, 95% CI 5.25–27.74), while baseline Eadyn was not predictive of IDH in this cohort. Other significant predictors of IDH included norepinephrine use (OR 16.35, 95% CI 3.87–68.98) and lower baseline MAP (OR 0.96, 95% CI 0.94–1.00). IDH and a positive PLR test were associated with lower 90-day survival (p < 0.001). Conclusions: The PLR test is a valuable tool for predicting IDH in critically ill AKI patients undergoing KRT, while baseline Eadyn did not demonstrate predictive value in this setting. Continuous hemodynamic monitoring, including assessment of preload dependency, may optimize patient management and potentially improve outcomes. Further research is warranted to validate these findings and develop targeted interventions to prevent IDH. [ABSTRACT FROM AUTHOR]

Transplant is the preferred treatment option for patients with end stage kidney disease. Patients with kidney disease should be informed about the transplant option, and if appropriate, referred for a transplant evaluation. Early referral is key to getting patients transplanted quicker because the evaluation is extensive and the waiting time on the deceased donor kidney transplant list is years. Understanding the steps in a transplant evaluation process can help providers and staff educate and support their patients through the evaluation process. [ABSTRACT FROM AUTHOR]

Background Dialysis modalities and their various treatment schedules result from complex compromises ('trade-offs') between medical, financial, technological, ergonomic, and ecological factors. This study targets summarizing the mutual influence of these trade-offs on (trans)portable, wearable, or even (partially) implantable haemodialysis (HD) systems, identify what systems are in development, and how they might improve quality of life (QoL) for patients with kidney failure. Methods HD as defined by international standard IEC 60601–2-16 was applied on a PUBMED database query regarding (trans)portable, wearable, and (partly) implantable HD systems. Out of 159 search results, 24 were included and scanned for specific HD devices and/or HD systems in development. Additional information about weight, size, and development status was collected by the internet and/or contacting manufacturers. International airplane hand baggage criteria formed the boundary between transportable and portable. Technology readiness levels (TRLs) were assigned by combining TRL scales from the European Union and NATO medical staff. Results The query revealed 13 devices/projects: seven transportable (six TRL9, one TRL5); two portable (one TRL6–7, one TRL4); two wearable (one TRL6, one frozen); and two partly implantable (one TRL4–5, one TRL2–3). Discussion Three main categories of technical approaches were distinguished: single-pass, dialysate regenerating, and implantable HD filter with extracorporeal dialysate regeneration (in climbing order of mobility). Conclusions Kidneys facilitate mobility by excreting strongly concentrated waste solutes with minimal water loss. Mimicking this kidney function can increase HD system mobility. Dialysate-regenerating HD systems are enablers for portability/wearability and, combined with durable implantable HD filters (once available), they may enable HD without needles or intravascular catheters. However, lack of funding severely hampers progress. [ABSTRACT FROM AUTHOR]

Background Primary glomerular disease (PGD) is a major cause of end-stage kidney disease (ESKD) leading to kidney replacement therapy (KRT). We aimed to describe incidence (trends) in individuals starting KRT for ESKD due to PGD and to examine their survival and causes of death. Methods We used data from the European Renal Association (ERA) Registry on 69 854 patients who started KRT for ESKD due to PGD between 2000 and 2019. ERA primary renal disease codes were used to define six PGD subgroups. We examined age and sex standardized incidence, trend of the incidence and survival. Results The standardized incidence of KRT for ESKD due to PGD was 16.6 per million population (pmp), ranging from 8.6 pmp in Serbia to 20.0 pmp in France. Immunoglobulin A nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS) had the highest incidences, of 4.6 pmp and 2.6 pmp, respectively. Histologically non-examined PGDs represented over 50% of cases in Serbia, Bosnia and Herzegovina, and Romania and were also common in Greece, Estonia, Belgium and Sweden. The incidence declined from 18.6 pmp in 2000 to 14.5 pmp in 2013, after which it stabilized. All PGD subgroups had 5-year survival probabilities above 50%, with crescentic glomerulonephritis having the highest risk of death [adjusted hazard ratio 1.8 (95% confidence interval 1.6–1.9)] compared with IgAN. Cardiovascular disease was the most common cause of death (33.9%). Conclusion The incidence of KRT for ESKD due to PGD showed large differences between countries and was highest and increasing for IgAN and FSGS. Lack of kidney biopsy facilities in some countries may have affected accurate assignment of the cause of ESKD. The recognition of the incidence and outcomes of KRT among different PGD subgroups may contribute to a more individualized patient care approach. [ABSTRACT FROM AUTHOR]

End stage kidney disease is rare in children and adolescents. The availability and types of kidney replacement therapy (KRT) vary widely, with a global prevalence of 18–100 per million age-related population (pmarp). Chronic peritoneal dialysis (PD) is considered the dialysis modality of choice in younger children given its almost universal applicability, cost-effectiveness, and the possibility of a home-based treatment. This is most compatible with a child's schooling and social life. Advances in technology have improved outcomes even for the youngest children, but mortality remains high, and the morbidity and burden of care should not be underestimated. Optimal management of children on dialysis requires a multidisciplinary team and consideration of the child and family's expectations. With few high-quality randomised trials, clinicians are reliant on prospective cohort studies and international registries to inform and improve management strategies. Children on dialysis have a lifetime of KRT ahead of them. The selection of dialysis modality and management must consider the principles of dialysis access preservation. This review summarises current epidemiology, principles of dialysis, PD access, modalities, prescriptions, and complications of PD, as well as a brief discussion on PD in infants with their unique ethical and technical considerations.

Kidney replacement therapy (KRT) can provide lifesaving support for children with severely impaired kidney function. The decision about who needs KRT and when is often complex. Many acute kidney problems will resolve with conservative maanagemenent but some children with chronic or acute kidney impairment will find themselves in a position where KRT is required either as a bridge to recovery or kidney transplantation. Less commonly, children with metabolic disorders may find that the ability of their own kidneys is overwhelmed by excessive production of certain metabolites. These children may also benefit from short term KRT. This article aims to help paediatricians in training understand which children need kidney replacement therapy, the various types of treatment available, and when they are used.

Hospitalized patients often have acute kidney disease (AKD) or chronic kidney disease (CKD), with important metabolic and nutritional consequences. Moreover, in case kidney replacement therapy (KRT) is started, the possible impact on nutritional requirements cannot be neglected. On this regard, the present guideline aims to provide evidence-based recommendations for clinical nutrition in hospitalized patients with KD. The standard operating procedure for ESPEN guidelines was used. Clinical questions were defined in both the PICO format, and organized in subtopics when needed, and in non-PICO questions for the more general topics. The literature search was from January 1st, 1999 until January 1st, 2020. Each question led to one or more recommendation/statement and related commentaries. Existing evidence was graded, as well as recommendations and statements were developed and agreed upon in a multistage consensus process. The present guideline provides 32 evidence-based recommendations and 8 statements, defining how to assess nutritional status, how to define patients at risk, how to choose the route of feeding, and how to integrate nutrition with KRT. In the final online voting, a strong consensus was reached in 84% at least of recommendations and 100% of statements. The presence of KD in hospitalized patients identifies a highly heterogeneous group of subjects with widely varying nutrient needs and intakes. Considering the high nutritional risk related with this clinical condition, an individualized approach consisting of nutritional status evaluation and monitoring, frequent evaluation of nutritional requirements, and careful integration with KRT should be planned to avoid both underfeeding and overfeeding. Practical recommendations and statements were developed, aiming at defining suggestions for everyday clinical practice in the individualization of nutritional support in this patient setting. Literature areas with scarce or without evidence were also identified, thus requiring further basic or clinical research. [ABSTRACT FROM AUTHOR]

Aim: Optimal care for patients with kidney failure reduces the risks of adverse health outcomes, including cardiovascular events and death. We evaluated data from the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN‐GKHA) to assess the capacity for quality service delivery for kidney failure care across countries and regions. Method: We explored the quality of kidney failure care delivery and the monitoring of quality indicators from data provided by an international survey of stakeholders from countries affiliated with the ISN from July to September 2022. Results: One hundred and sixty seven countries participated in the survey, representing about 97.4% of the world's population. In countries where haemodialysis (HD) was available, 81% (n = 134) provided standard HD sessions (three times weekly for 3–4 h per session) to patients. Among countries with peritoneal dialysis (PD) services, 61% (n = 101) were able to provide standard PD care (3–4 exchanges per day). In high‐income countries, 98% (n = 62) reported that >75% of centers regularly monitored dialysis water quality for bacteria compared to 28% (n = 5) of low‐income countries (LICs). Capacity to monitor the administration of immunosuppression drugs was generally available in 21% (n = 4) of LICs, compared to 90% (n = 57) of high‐income countries. There was significant variability between and within regions and country income groups in reporting the quality of services utilized for kidney replacement therapies. Conclusion: Quality assurance standards on diagnostic and treatment tools were variable and particularly infrequent in LICs. Standardization of delivered care is essential for improving outcomes for people with kidney failure. [ABSTRACT FROM AUTHOR]

Background: Access to pediatric dialysis is challenged in low-resource settings due to high costs, scarcity of equipment, and the lack of qualified personnel availability. We demonstrated the manual single lumen alternating micro-batch (mSLAMB) device can remove small solutes in vitro without the need for electricity, batteries, or pumps. We developed a new version (Kirpa Kit™) to address some of the technical limitations of mSLAMB. Here, we compare the in vitro clearance performance and ease of use of the Kirpa Kit™ with that of prior mSLAMB configurations. Methods: A mixture of expired packed red blood cells, 0.9% NaCl, urea, and heparin was used to test the efficiency of two mSLAMB configurations and the Kirpa Kit™ in removing potassium and urea. Clearance was evaluated by measuring percent reduction after 25-min sessions with each device. A survey was used to evaluate the ease of use of each configuration. Results: The Kirpa Kit™ achieved a median urea reduction of 82.4% and potassium reduction of 82.1%, which were higher than those achieved with the best-performing mSLAMB configuration (urea 71.9%, potassium 75.4%). The Kirpa Kit™ was easier to use with a shorter perceived time of use than the mSLAMB. Conclusions: The Kirpa Kit™, evolution of mSLAMB, is easy to use and may have improved efficacy, making it an optimal candidate for in vivo testing. [ABSTRACT FROM AUTHOR]

Background: Children with established kidney failure may have additional medical conditions influencing kidney care and outcomes. This cross-sectional study aimed to examine the prevalence of co-existing diseases captured in the electronic hospital record compared to UK Renal Registry (UKRR) data and differences in coding. Methods: The study population comprised children aged < 18 years receiving kidney replacement therapy (KRT) in England and Wales on 31/12/2016. Comorbidity data at KRT start was examined in the hospital record and compared to UKRR data. Agreement was assessed by the kappa statistic. Associations between patient and clinical factors and likelihood of coding were examined using multivariable logistic regression. Results: A total of 869 children (62.5% male) had data linkage for inclusion. UKRR records generally reported a higher prevalence of co-existing disease than electronic health records; congenital, non-kidney disease was most commonly reported across both datasets. The highest sensitivity in the hospital record was seen for congenital heart disease (odds ratio (OR) 0.65, 95% confidence interval (CI) 0.51, 0.78) and malignancy (OR 0.63, 95% CI 0.41, 0.85). At best, moderate agreement (kappa ≥ 0.41) was seen between the datasets. Factors associated with higher odds of coding in hospital records included age, while kidney disease and a higher number of comorbidities were associated with lower odds of coding. Conclusions: Health records generally under-reported co-existing disease compared to registry data with fair-moderate agreement between datasets. Electronic health records offer a non-selective overview of co-existing disease facilitating audit and research, but registry processes are still required to capture paediatric-specific variables pertinent to kidney disease.

Background: Young adults living with kidney failure make decisions to select a kidney replacement therapy choice in partnership with healthcare professionals. However, little is known about how they experience kidney replacement therapy treatment decision‐making and the impact this has on their well‐being. Objectives: To explore young adults living with kidney failure experiences of treatment decision‐making. The treatment decision‐making investigated is about the choice of dialysis and/or kidney transplant options. Design: A qualitative interpretive hermeneutic phenomenology study. Participants: Purposeful sampling was used to recruit young adults with kidney failure from social media, electronic media such as local kidney group websites and word of mouth. Semistructured interviews were conducted with (n = 18) participants aged 18–30 years. Approach: Inductive analysis of the data were performed using Braun and Clarke's thematic analysis framework. Findings: The five themes generated were (1) awareness and anticipation of future kidney replacement therapy decision; (2) health information and education; (3) engaging in decision‐making, support and choices; (4) implementation of kidney replacement therapy and transitioning into the new normal life and (5) the impact of decision‐making and choice on well‐being. Conclusions: Decision‐making significantly affected young adults' psychosocial and mental well‐being. Young adults had unmet informational and decisional needs and struggled to cope due to lack of support. A four‐talk model, with an implement talk phase added to the existing three‐talk (team talk, option talk, decision talk) shared decision‐making model, would promote a focus on the implementation of choice and support the transitioning from previous life to long‐term dependence on treatment.

Abstract Background The development of acute kidney injury (AKI) post-cardiac surgery significantly increases patient morbidity and healthcare costs. Prior researches have established Syndecan-1 (SDC-1) as a potential biomarker for endothelial injury and subsequent acute kidney injury development. This study assessed whether postoperative SDC-1 levels could further predict AKI requiring kidney replacement therapy (AKI-KRT) and AKI progression. Methods In this prospective study, 122 adult cardiac surgery patients, who underwent valve or coronary artery bypass grafting (CABG) or a combination thereof and developed AKI within 48 h post-operation from May to September 2021, were monitored for the progression to stage 2–3 AKI or the need for KRT. We analyzed the predictive value of postoperative serum SDC-1 levels in relation to multiple endpoints. Results In the study population, 110 patients (90.2%) underwent cardiopulmonary bypass, of which thirty received CABG or combined surgery. Fifteen patients (12.3%) required KRT, and thirty-eight (31.1%) developed progressive AKI, underscoring the severe AKI incidence. Multivariate logistic regression indicated that elevated SDC-1 levels were independent risk factors for progressive AKI (OR = 1.006) and AKI-KRT (OR = 1.011). The AUROC for SDC-1 levels in predicting AKI-KRT and AKI progression was 0.892 and 0.73, respectively, outperforming the inflammatory cytokines. Linear regression revealed a positive correlation between SDC-1 levels and both hospital (β = 0.014, p = 0.022) and ICU stays (β = 0.013, p

Conclusion: Elevated postoperative SDC-1 levels significantly predict AKI progression and AKI-KRT in patients following cardiac surgery. The study's findings support incorporating SDC-1 level monitoring into post-surgical care to improve early detection and intervention for severe AKI. [ABSTRACT FROM AUTHOR]

Background: Hemolytic uremic syndrome (HUS) is an important cause of acute kidney injury in children. HUS is known as an acute disease followed by complete recovery, but patients may present with kidney abnormalities after long periods of time. This study evaluates the long-term outcome of Shiga toxin-producing Escherichia coli-associated HUS (STEC-HUS) in pediatric patients, 10 years after the acute phase of disease to identify risk factors for long-term sequelae. Methods: Over a 6-year period, 619 patients under 18 years of age with HUS (490 STEC-positive, 79%) were registered in Austria and Germany. Long-term follow-up data of 138 STEC-HUS-patients were available after 10 years for analysis. Results: A total of 66% (n = 91, 95% CI 0.57–0.73) of patients fully recovered showing no sequelae after 10 years. An additional 34% (n = 47, 95% CI 0.27–0.43) presented either with decreased glomerular filtration rate (24%), proteinuria (23%), hypertension (17%), or neurological symptoms (3%). Thirty had sequelae 1 year after STEC-HUS, and the rest presented abnormalities unprecedented at the 2-year (n = 2), 3-year (n = 3), 5-year (n = 3), or 10-year (n = 9) follow-up. A total of 17 patients (36.2%) without kidney abnormalities at the 1-year follow-up presented with either proteinuria, hypertension, or decreased eGFR in subsequent follow-up visits. Patients needing extracorporeal treatments during the acute phase were at higher risk of presenting symptoms after 10 years (p < 0.05). Conclusions: Patients with STEC-HUS should undergo regular follow-up, for a minimum of 10 years following their index presentation, due to the risk of long-term sequelae of their disease. An initial critical illness, marked by need of kidney replacement therapy or plasma treatment may help predict poor long-term outcome. [ABSTRACT FROM AUTHOR]

Albumin is used commonly across a wide range of clinical settings to improve hemodynamics, to facilitate fluid removal, and to manage complications of cirrhosis. The International Collaboration for Transfusion Medicine Guidelines developed guidelines for the use of albumin in patients requiring critical care, undergoing cardiovascular surgery, undergoing kidney replacement therapy, or experiencing complications of cirrhosis. Cochairs oversaw the guideline development process and the panel included researchers, clinicians, methodologists, and a patient representative. The evidence informing this guideline arises from a systematic review of randomized clinical trials and systematic reviews, in which multiple databases were searched (inception through November 23, 2022). The panel reviewed the data and formulated the guideline recommendations using Grading of Recommendations Assessment, Development, and Evaluation methodology. The guidelines were revised after public consultation. The panel made 14 recommendations on albumin use in adult critical care (three recommendations), pediatric critical care (one recommendation), neonatal critical care (two recommendations), cardiovascular surgery (two recommendations), kidney replacement therapy (one recommendation), and complications of cirrhosis (five recommendations). Of the 14 recommendations, two recommendations had moderate certainty of evidence, five recommendations had low certainty of evidence, and seven recommendations had very low certainty of evidence. Two of the 14 recommendations suggested conditional use of albumin for patients with cirrhosis undergoing large-volume paracentesis or with spontaneous bacterial peritonitis. Twelve of 14 recommendations did not suggest albumin use in a wide variety of clinical situations where albumin commonly is transfused. Currently, few evidence-based indications support the routine use of albumin in clinical practice to improve patient outcomes. These guidelines provide clinicians with actionable recommendations on the use of albumin. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury (AKI) is a common complication of critical illness and associated with high morbidity and mortality. Optimal timing of continuous kidney replacement therapy (CKRT) in children is unknown. We aimed to measure the association between timing of initiation and mortality. Methods: This is a single-center retrospective cohort study of pediatric patients receiving CKRT from 2013 to 2019. The primary exposure, time to CKRT initiation, was measured from onset of stage 3 AKI during hospitalization (defined using Kidney Disease: Improving Global Outcomes creatinine and urine output criteria) and analyzed as both a continuous and categorical variable. The primary outcome was ICU mortality. Results: Ninety-nine patients met criteria for analysis. Overall mortality was 39% (39/99). Median time from stage 3 AKI onset to CKRT initiation was 1.5 days in survivors and 5.5 days in nonsurvivors (p < 0.001). In multivariable analysis, increased time to CKRT initiation was independently associated with mortality [OR 1.02 per hour (95% CI 1.01–1.04), p < 0.001]. Longer time to CKRT initiation was associated with higher odds of mortality in ascending time intervals. Patients started on CKRT > 2 days compared to < 2 days after stage 3 AKI onset had higher mortality (65% vs. 5%, p < 0.001), longer median ICU length of stay (25 vs. 12 d, p < 0.001), longer median CKRT duration (11 vs. 5 d, p < 0.001), and fewer AKI-free days (0 vs. 14 d, p < 0.001). Conclusions: Longer time to initiation of CKRT after development of severe AKI is independently associated with mortality. Consideration of early CKRT in this high-risk population may be a strategy to reduce mortality and improve recovery of kidney function. However, there remains significant heterogeneity in the definition of early versus late initiation and the optimal timing of CKRT remains unknown. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury (AKI) is a life-threatening condition, especially in extreme age groups and when kidney replacement therapy (KRT) is necessary. Studies worldwide report mortality rates of 10–63% in pediatric patients undergoing KRT. Methods: Over 13 years, this multicenter study analyzed data from 693 patients with AKI, all receiving KRT, across 74 hospitals and medical facilities in Rio de Janeiro, Brazil. Results: The majority were male (59.5%), under one year old (55.6%), and treated in private hospitals (76.5%). Sixty-six percent had comorbidities. Pneumonia and congenital heart disease were the most common admission diagnoses (21.5% and 20.2%, respectively). The mortality rate was 65.2%, with lower rates in patients over 12 years (50%). Older age was protective (HR: 2.35, IQR [1.52–3.62] for neonates), and primary kidney disease had a three-fold lower mortality rate. ICU team experience (HR: 0.74, IQR [0.60–0.91]) correlated with lower mortality, particularly in hospitals treating 20 or more patients. Among the deceased, 40% died within 48 h of KRT initiation, suggesting possible late referral or treatment futility. Conclusions: This study confirms the high mortality in pediatric dialytic AKI in middle-income countries, underlining early mortality and offering critical insights for improving outcomes.

Aim: To determine the change in incidence and prevalence of chronic kidney disease (CKD) in rural and remote communities over the last decade. Methods: We examined the change in age‐standardized incidence and prevalence in Tasmania between 2010 and 2020, using a linked dataset that included any adult with a creatinine test taken in a community laboratory during the study period (n = 581 513; 87.8% of the state's adult population). We defined CKD as two measures of eGFR <60 mL/min per 1.73 m2, at least 3 months apart. Results: State‐wide age‐standardized prevalence of CKD increased by 28% in the decade to 2020, from 516 to 659 per 10 000 population. Prevalence in men increased 31.3% and women 24.8%. The greatest increase in age‐standardized prevalence was seen in rural or remote communities with an increase of 36.6% overall, but with considerable variation by community (range + 0.4% to +88.3%). The increase in the actual number of people with CKD in the decade to 2020 was 67%, with the number of women increasing by 58% and men by 79%. Conclusion: The age‐standardized prevalence of CKD in rural and remote regions has increased considerably over the past decade, likely compounded by limited access to primary and secondary healthcare. These findings highlight the need to ensure healthcare resources are directed to areas of greatest need. Summary at a glance: Whilst the incidence of chronic kidney disease has remained stable over the decade from 2010 to 2020, the age‐standardised prevalence increased 28%. There is considerable variation by small community with the greatest change being in rural or remote areas. [ABSTRACT FROM AUTHOR]

Background: The association between the administration of sodium-glucose cotransporter 2 inhibitors (SGLT2is) during acute kidney injury (AKI) and the incidence of major adverse kidney events (MAKEs) is not known. Methods: This retrospective cohort study included patients with AKI and compared the outcomes for those who were treated with SGLT2is during hospitalization and those without SGLT2i treatment. The associations of SGLT2i use with MAKEs at 10 and 30-90 days, each individual MAKE component, and the pre-specified patient subgroups were analyzed. Results: From 2021 to 2023, 374 patients were included in the study-316 without SGLT2i use and 58 with SGLT2i use. Patients who were treated with SGLT2is were older; had a greater prevalence of diabetes, hypertension, chronic heart failure, and chronic kidney disease; required hemodialysis less often; and presented stage 3 AKI less frequently than those who were not treated with SGLT2is. Logistic regression analysis with nearestneighbor matching revealed that SGLT2i use was not associated with the risk of MAKE10 (OR 1.08 [0.45-2.56]) or with MAKE30-90 (OR 0.76 [0.42-1.36]). For death, the stepwise approach demonstrated that SGLT2i use was associated with a reduced risk (OR 0.08; 0.01-0.64), and no effect was found for kidney replacement therapy (KRT). The subgroups of patients who experienced a reduction in the risk of MAKEs in patients with AKI treated with SGLT2is were those older than 61 years, those with an eGFR >81, and those without a history of hypertension or DM (p ≤ 0.05 for all). Conclusion: The use of SGLT2is during AKI had no effect on short- or mediumterm MAKEs, but some subgroups of patients may have experienced benefits from SGLT2i treatment. [ABSTRACT FROM AUTHOR]

Background: Ischemic optic neuropathy (ION) is exceedingly rare in children on dialysis, resulting from poor perfusion of the optic nerve, and presents as sudden acute painless vision loss. Case–diagnosis/treatment: We report the case of a 3-year-old male with stage 5 chronic kidney disease (CKD 5) due to focal segmental glomerulosclerosis (FSGS) status post-bilateral nephrectomy on chronic hemodialysis who had acute loss of vision several hours after a hemodialysis session. Earlier that day, he had a drop in blood pressure intra-dialysis to 89/67 mmHg, with at home blood pressures ranging 90/60 to 150/100 mmHg. The patient was treated with tight blood pressure control to maintain blood flow and prevent blood pressure lability, received high-dose corticosteroids with a corticosteroid taper, and placed on high-dose erythropoietin for neuroprotective effect. He regained partial vision beginning approximately 1 month after presentation. Conclusions: The exact cause of our patient's simultaneous bilateral anterior and posterior ION, confirmed via MRI and fundoscopic examination, is unclear; however, is likely secondary to a combination of fluctuating blood pressure, anemia, anephric status, and hemodialysis. This highlights the need for close blood pressure monitoring, management of anemia, and more diligent ophthalmologic screening in pediatric patients on chronic hemodialysis. [ABSTRACT FROM AUTHOR]

Background: Dialysis might not benefit all older patients with kidney failure, particularly those with multimorbid conditions and frailty. Patients' and healthcare professionals' awareness of the presence of geriatric impairments could improve outcomes by tailoring treatment plans and decisions for individual patients. Objective: We aimed to explore the perspectives of patients and healthcare professionals on nephrology‐tailored geriatric assessment to fuel decision‐making for treatment choices in older patients with kidney failure. Design: In an exploratory qualitative study using focus groups, participants discussed perspectives on the use and value of nephrology‐tailored geriatric assessment for the decision‐making process to start or forego dialysis. Participants and Measurements: Patients (n = 18) with kidney failure, caregivers (n = 4), and professionals (n = 25) were purposively sampled from 10 hospitals. Interviews were audio‐recorded, transcribed verbatim and inductively analysed using thematic analysis. Results: Three main themes emerged that supported or impeded decision‐making in kidney failure: (1) patient psycho‐social situation; (2) patient‐related factors on modality choice; (3) organisation of health care. Patients reported feeling vulnerable due to multiple chronic conditions, old age, experienced losses in life and their willingness to trade longevity for quality of life. Professionals recognised the added value of nephrology‐tailored geriatric assessment in three major themes: (i) facilitating continual holistic assessment, (ii) filling the knowledge gap, and (iii) uncovering important patient characteristics. Conclusions: nephrology‐tailored geriatric assessment was perceived as a valuable tool to identify geriatric impairments in older patients with kidney failure. Integration of its outcomes can facilitate a more holistic approach to inform choices and decisions about kidney replacement therapy. [ABSTRACT FROM AUTHOR]

Abstract Background Limited data existed on the burden of coronavirus disease 2019 (COVID-19) renal complications and the outcomes of the most critical patients who required kidney replacement therapy (KRT) during intensive care unit (ICU) stay. We aimed to describe mortality and renal function at 90 days in patients admitted for COVID-19 and KRT. Methods A retrospective cohort study of critically ill patients admitted for COVID-19 and requiring KRT from March 2020 to January 2022 was conducted in an Italian ICU from a tertiary care hospital. Primary outcome was mortality at 90 days and secondary outcome was kidney function at 90 days. Results A cohort of 45 patients was analyzed. Mortality was 60% during ICU stay and increased from 64% at the time of hospital discharge to 71% at 90 days. Among 90-day survivors, 31% required dialysis, 38% recovered incompletely, and 31% completely recovered renal function. The probability of being alive and dialysis-free at 3 months was 22%. Conclusions Critically ill patients with COVID-19 disease requiring KRT during ICU stay had elevated mortality rate at 90 days, with low probability of being alive and dialysis-free at 3 months. However, a non-negligible number of patients completely recovered renal function.

Abstract Background Toxic renal effects of myoglobin following rhabdomyolysis can cause acute kidney injury (AKI) with the necessity of kidney replacement therapy (KRT). Fast elimination of myoglobin seems notable to save kidney function and intensify kidney repair. Clinical data regarding efficacy of KRT in critical care patients with rhabdomyolysis and AKI are limited. This retrospective analysis aimed to identify differences between conservative therapy and different modalities of KRT regarding myoglobin elimination and clinical outcome. Methods This systematic, retrospective, single-center study analyzed 328 critical care patients with rhabdomyolysis (myoglobin > 1000 µg/l). Median reduction rate of myoglobin after starting KRT was calculated and compared for different modalities. Multivariate logistic regression models were established to identify potential confounder on hospital mortality. Filter lifetime of the various extracorporeal circuits was analyzed by Kaplan–Meier curves. Results From 328 included patients 171 required KRT. Health condition at admission of this group was more critical compared to patient with conservative therapy. Myoglobin reduction rate did not differ between the groups (KRT 49% [30.8%; 72.2%] vs. conservative treatment (CT) 61% [38.5%; 73.5%]; p = 0.082). Comparison between various extracorporeal procedures concerning mortality showed no significant differences. Hospital mortality was 55.6% among patients with KRT and 18.5% with CT (p

Abstract Background Peritoneal dialysis (PD) remains underutilised in Germany, prompting the initiation of the Sustainable Intensification of Peritoneal Dialysis in Schleswig–Holstein (SKIP-SH) project. The SKIP-SH cohort study aims to demonstrate the presumed benefits of PD, including enhanced quality of life and reduced healthcare personnel requirements, and to generate data to strengthen the use of PD. Methods The prospective SKIP-SH cohort study recruits patients with advanced chronic kidney disease (CKD) and their caregivers. Comprehensive data, including demographic information, medical history, clinical course, laboratory data, and quality-of-life assessments, are collected. Additionally, biomaterials will be obtained. Primary study objectives are documenting the clinical course and complications, time on therapy for new dialysis patients, reasons influencing treatment modality choices, circumstances at the initiation of dialysis, and quality of life for patients with CKD and their caregivers. The collected biomaterials will serve as a basis for further translational research. Secondary objectives include identifying factors impacting disease-related quality of life, clinical complications, and therapy dropout, estimating ecological footprints, and evaluating healthcare costs and labour time for initiating and sustaining PD treatment. Discussion PD is notably underutilised in Germany. The current therapy approach for advanced CKD often lacks emphasis on patient-focused care and quality-of-life considerations. Furthermore, adequate explorative research programs to improve our knowledge of mechanisms leading to disease progression and therapy failure in PD patients are scarce. The overarching goal of the SKIP-SH cohort study is to address the notably low PD prevalence in Germany whilst advocating for a shift towards patient-focused care, quality-of-life considerations, and robust translational research. Trial registration This study was registered with the German trial registry (Deutsches Register klinischer Studien) on November 7, 2023, under trial number DRKS00032983.

Introduction: Continuous ambulatory peritoneal dialysis is an important modality of renal replacement therapy in children. Catheter dysfunction (commonly obstruction) is a major cause of morbidity and is a significant concern that hampers renal replacement therapy. As omentum is a significant cause of obstruction, some recommend routine omentectomy during insertion of the peritoneal dialysis catheter. Omentopexy rather than omentectomy has been described in adults to spare the omentum as it may be needed as a spare part in many conditions. Laparoscopic approach is commonly preferred as it provides global evaluation of the peritoneal space, proper location of the catheteral end in the pelvis and lesser morbidity due to inherent minimally invasive nature. Aim: The aim of this study is to present the technique of laparoscopic peritoneal dialysis catheter placement in children with concurrent omentopexy. Methods: We retrospectively evaluated our patients who underwent laparoscopic placement of peritoneal dialysis catheter with concomitant omentopexy or omentectomy. Results: A total of 30 patients were enrolled who received either omentectomy (n = 18) or omentopexy (n = 12). Four catheters were lost in the omentopexy group (33%) and 3 in the omentectomy group (17%), but none were related to omental obstruction. Three out of 4 patients in the omentopexy group and 2 out of 3 patients in the omentectomy group had a previous abdominal operation as a potential cause of catheter loss. Previous history of abdominal surgery was present in 6 patients (50%) in the omentopexy group and 3 patients (17%) in the omentectomy group. Conclusions: As omentum was associated with catheter failure, omentectomy is commonly recommended. Alternatively, omentopexy can be preferred in children to spare an organ that may potentially be necessary for many surgical reconstructive procedures in the future. Laparoscopic peritoneal dialysis catheter placement with concomitant omentopexy appears as a feasable and reproducible technique. Although the catheter loss seems to be higher in the omentopexy group, none was related with the omentopexy procedure and may be related to the higher rate of history of previous abdominal operations in this group.

Acute kidney injury (AKI) is a complex and life-threatening condition with multifactorial etiologies, ranging from ischemic injury to nephrotoxic exposures. Management is founded on treating the underlying cause of AKI, but supportive care—via fluid management, vasopressor therapy, kidney replacement therapy (KRT), and more—is also crucial. Blood pressure targets are often higher in AKI, and these can be achieved with fluids and vasopressors, some of which may be more kidney-protective than others. Initiation of KRT is controversial, and studies have not consistently demonstrated any benefit to early start dialysis. There are no targeted pharmacotherapies for AKI itself, but some do exist for complications of AKI; additionally, medications become a key aspect of AKI management because changes in renal function and dialysis support can lead to issues with both toxicities and underdosing. This review will cover existing literature on these and other aspects of AKI treatment. Additionally, this review aims to identify gaps and challenges and to offer recommendations for future research and clinical practice. [ABSTRACT FROM AUTHOR]

Chronic kidney disease poses a growing global health concern, as an increasing number of patients progress to end-stage kidney disease requiring kidney replacement therapy, presenting various challenges including shortage of care givers and cost-related issues. In this narrative essay, we explore innovative strategies based on in-depth literature analysis that may help healthcare systems face these challenges, with a focus on digital health technologies (DHTs), to enhance removal and ensure better control of broader spectrum of uremic toxins, to optimize resources, improve care and outcomes, and empower patients. Therefore, alternative strategies, such as self-care dialysis, home-based dialysis with the support of teledialysis, need to be developed. Managing ESKD requires an improvement in patient management, emphasizing patient education, caregiver knowledge, and robust digital support systems. The solution involves leveraging DHTs to automate HD, implement automated algorithm-driven controlled HD, remotely monitor patients, provide health education, and enable caregivers with data-driven decision-making. These technologies, including artificial intelligence, aim to enhance care quality, reduce practice variations, and improve treatment outcomes whilst supporting personalized kidney replacement therapy. This narrative essay offers an update on currently available digital health technologies used in the management of HD patients and envisions future technologies that, through digital solutions, potentially empower patients and will more effectively support their HD treatments.

Peritoneal dialysis (PD) is a form of kidney replacement therapy with the major advantage that it can be performed at home. This has a positive impact on patients' autonomy and quality of life. However, the dialysis population is ageing and physical and/or cognitive impairments are common. These limitations often form a barrier to PD and contribute to the low incidence and prevalence of PD in Europe. Assisted PD can be a solution to this problem. Assisted PD refers to a patient being assisted by a person or device in performing all or part of their dialysis-related tasks, thereby making PD more accessible to elderly but also younger frail patients. In this way, offering an assisted PD program can help lower the threshold for initiating PD. In this review, we provide an overview of the epidemiology of assisted PD in Europe, we discuss the different categories and clinical outcomes of assisted PD, and we present how assisted PD can be implemented in clinical practice as a possible strategy to increase and maintain home dialysis in Europe.

BACKGROUND: This case report presents a history of familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). The patient was admitted to the hospital with hypertensive encephalopathy. FHHNC is a rare autosomal recessive disease caused by mutations in CLDN16 or CLDN19, resulting in insufficient magnesium and calcium kidney reabsorption. FHHNC manifestation starts in childhood, and over the years, its development leads to nephrocalcinosis and, consequently, chronic kidney disease (CKD), which is not slowed by routine administration of magnesium and thiazide diuretics. Ultimately, all FHHNC patients need kidney replacement therapy (KRT). CASE PRESENTATION: The patient was a 28-year-old male diagnosed with FHHNC and admitted to the emergency room due to hypertensive encephalopathy. The current situation was the patient's second hospitalization related to a hypertensive emergency caused by under-dialysis. Despite the signs of insufficient functioning of peritoneal dialysis (PD) (the primary chosen form of KRT), the patient refused the proposed conversion to hemodialysis (HD). Symptoms observed upon admission included disorientation, anxiety, and severe hypertension, reaching 213/123 mmHg. Due to his clinical condition, the patient was transferred to the intensive care unit (ICU), where the introduction of continuous veno-venous hemodiafiltration and hypotensive therapy stabilized blood pressure. Within the next few days, his state improved, followed by discharge from ICU. Eventually, the patient agreed to transition from PD to in-center HD. At the time, he was qualified for kidney transplantation, waiting for a compatible donation. CKD and dialysis are factors that significantly affect a patient's quality of life, especially in young patients with congenital diseases like FHHNC. CONCLUSIONS: For the aforementioned reasons, appropriate education and psychological support should be ensured to avoid the harmful effects of therapy non-compliance. [ABSTRACT FROM AUTHOR]

Background and Aims Patients with kidney failure have a higher risk of cardiovascular disease compared with the general population. Whilst temporal trends of myocardial infarction and stroke are declining in the general population, these have not been evaluated in patients with kidney failure. This study aimed to describe national trends in the incidence, treatment, and outcomes of myocardial infarction and stroke in patients with kidney failure (i.e. on dialysis or with a kidney transplant) over a 20-year period, stratified by age and sex. Methods In this retrospective national data linkage study, all patients with kidney failure in Scotland (UK) receiving kidney replacement therapy between January 1996 and December 2016 were linked to national hospitalization, prescribing, and death records. The primary outcomes were the incidence of myocardial infarction and stroke, and subsequent cardiovascular death. Generalized additive models were constructed to estimate age-standardized, sex-stratified incidence rates and trends in cardiovascular and all-cause death. Results Amongst 16 050 patients with kidney failure [52 (SD 15) years; 41.5% women], there were 1992 [66 (SD 12) years; 34.8% women] and 996 [65 (SD 13) years; 45.1% women] incident myocardial infarctions and strokes, respectively, between January 1996 and December 2016. During this period, the age-standardized incidence of myocardial infarction per 100 000 decreased in men {from 4376 [95% confidence interval (CI) 3998–4785] to 1835 (95% CI 1692–1988)} and women [from 3268 (95% CI 2982–3593) to 1369 (95% CI 1257–1491)]. Similarly, the age-standardized incidence of stroke per 100 000 also decreased in men [from 1978 (95% CI 1795–2175) to 799 (95% CI 729–875)] and women [from 2234 (95% CI 2031–2468) to 903 (95% CI 824–990)]. Compared with the general population, the incidence of myocardial infarction was four- to eight-fold higher in patients with kidney failure, whilst for stroke it was two- to four-fold higher. The use of evidence-based cardioprotective treatment increased over the study period, and the predicted probability of cardiovascular death within 1 year of myocardial infarction for a 66-year-old patient with kidney failure (mean age of the cohort) fell in men (76.6% to 38.6%) and women (76.8% to 38.8%), and also decreased in both sexes following stroke (men, from 63.5% to 41.4%; women, from 67.6% to 45.8%). Conclusions The incidence of myocardial infarction and stroke has halved in patients with kidney failure over the past 20 years but remains significantly higher than in the general population. Despite improvements in treatment and outcomes, the prognosis of these patients following myocardial infarction and stroke remains poor. [ABSTRACT FROM AUTHOR]

Background: School attendance and life participation, particularly sport, is a high priority for children with chronic kidney disease (CKD). This study is aimed at assessing the association between CKD stage, sports participation, and school absences in children with CKD. Methods: Using data from the binational Kids with CKD study (ages 6–18 years, n = 377), we performed multivariable regression to evaluate the association between CKD stage, school absences, and sports participation. Results: Overall, 62% of participants played sport with the most frequent sport activities engaged in being swimming (17%) and soccer (17%). Compared to children with CKD 1–2, the incidence rate ratios (IRR) (95% CI) for sports participation amongst children with CKD 3–5, dialysis, or transplant were 0.84 (0.64–1.09), 0.59 (0.39–0.90), and 0.75 (0.58–0.96), respectively. The median (IQR) days of school absences within a four-week period were 1 day (0–1), with children on dialysis reporting the highest number of school absences (9 days (5–15)), followed by transplant recipients (2 days (1–7)), children with CKD 3–5 (1 day (0–3)), and with CKD 1–2 (1 day (0–3)). Duration of CKD modified the association between CKD stage and school absences, with children with a transplant experiencing a higher number of missed school days with increasing duration of CKD, but not in children with CKD 1–5 or on dialysis (p-interaction < 0.01). Conclusions: Children receiving dialysis and with a kidney transplant had greater school absences and played fewer sports compared to children with CKD stages 1–2. Innovative strategies to improve school attendance and sport participation are needed to improve life participation of children with CKD. [ABSTRACT FROM AUTHOR]

Background: Turkish Society of Nephrology registry collects data on hemodialysis, peritoneal dialysis, and transplantation annually. Registry reports are printed every year as a booklet, and this is the 33rd year of registry reports. The registry is in close collaboration with international registries. Methods: In this paper, we summarized data from the 2022 registry report; additionally, we also provided yearly trends of managing end-stage kidney disease. Results: The number of patients on kidney replacement therapy increases; at the end of 2022, 86 665 patients were on kidney replacement therapy. The prevalence and incidence of end-stage kidney disease were 1016.2 and 160.9 per million population, respectively. Diabetes was the most common cause of end-stage kidney disease. Hemodialysis (71.22%) was the most common type of treatment modality, followed by transplantation (24.68%) and peritoneal dialysis (4.1%). Conclusion: End-stage kidney disease is a critical and growing health problem for our country. The renal registry of the Turkish Ssociety of Nephrology is one of the leading tools for providing current and sound data on this public health problem. [ABSTRACT FROM AUTHOR]

Introduction: Peritoneal dialysis (PD) is one of the kidney replacement therapies (KRT). Patients' choice of KRT is influenced by personal causes, familial factors, factors related to healthcare professionals, and social factors. Methods: This study included 341 patients. PD patients who changed their KRT selection were asked for the reasons to change with a questionnaire. Results: Of the patients who initially chose PD, only 48.5% received KRT by PD. Five (20%) of the patients gave up PD compulsorily because they heard that the risk of infection with PD was higher, eight (40%) thought they could not do it, four (20%) because they needed to do assisted PD but had no relatives to do it, and three (15%) because they had abdominal surgery. Conclusion: We believe that the fact that KRT training is carried out by a PD trained team and that patients are provided with assistance for PD will be effective in addressing the concerns of patients with PD undecided.

Fast elimination of myoglobin seems notable to save kidney function and intensify kidney repair. Clinical data regarding efficacy of KRT in critical care patients with rhabdomyolysis and AKI are limited. This retrospective analysis aimed to identify differences between conservative therapy and different modalities of KRT regarding myoglobin elimination and clinical outcome. Methods: This systematic, retrospective, single-center study analyzed 328 critical care patients with rhabdomyolysis (myoglobin > 1000 µg/l). Median reduction rate of myoglobin after starting KRT was calculated and compared for different modalities. Multivariate logistic regression models were established to identify potential confounder on hospital mortality. Filter lifetime of the various extracorporeal circuits was analyzed by Kaplan–Meier curves. Results: From 328 included patients 171 required KRT. Health condition at admission of this group was more critical compared to patient with conservative therapy. Myoglobin reduction rate did not differ between the groups (KRT 49% [30.8%; 72.2%] vs. conservative treatment (CT) 61% [38.5%; 73.5%]; p = 0.082). Comparison between various extracorporeal procedures concerning mortality showed no significant differences. Hospital mortality was 55.6% among patients with KRT and 18.5% with CT (p < 0.001). Multivariate logistic regression model identified requirement for KRT (OR: 2.163; CI: 1.061–4.407); p = 0.034) and the SOFA Score (OR: 1.111; CI: 1.004–1.228; p = 0.041) as independent predictive factors for hospital mortality. When comparing specific KRT using multivariate regression, no benefit was demonstrated for any treatment modality. Life span of the extracorporeal circuit was shorter with CVVH compared to that of others (log-Rank p = 0.017). Conclusions: This study emphasizes that AKI requiring KRT following rhabdomyolysis is accompanied by high mortality rate. Differences in myoglobin reduction rate between various KRTs could not be confirmed, but CVVH was associated with reduced filter lifetime compared to other KRTs, which enable myoglobin elimination, too.

Introduction: Patients with peritoneal dialysis (PD) who develop volume overload (VO) have high risks of dropout from death or advancement to hemodialysis. We aimed to determine the mortality rates, associated factors, and patient survival rates of PD patients who had history of admission from VO. Methods: We reviewed data of PD patients who were registered in the Database of Peritoneal dialysis in EXcel (DPEX) from January 2008 to December 2018. They were followed until death or the end of June 2020. Patients with at least 18 years of age and history of admission from VO were classified into two groups. Group A had a history of VO after starting PD. Group B had a history of VO before and after starting PD. The mortality rates were calculated. Patient survival and associated factors were evaluated by Kaplan-Meier and multiple cox regression, respectively. Results: 1,882 patients had history of admission from VO. The overall mortality rate was 28.9 per 100 person-years. The mortality rates in group A and group B were 25.4 and 41.7 per 100 person-years, respectively. Patients in group A had lower age, fewer comorbidities, longer dialysis vintage, and better patient survival than those in group B. Factors related to worsening patient survival were increased age, diabetes, and comorbidities. Conclusion: Patients with history of admission from VO before and after the start of PD had higher mortality rates than those with history of admission from VO after PD. Increased age, diabetes, and comorbidities were the associated factors of patient survival. [ABSTRACT FROM AUTHOR]
