A Japanese female in her 20 s with a history of self-induced vomiting was diagnosed with severe renal failure and referred to our department. She was extremely lean, with a body mass index of 9.6 kg/m2. Computed tomography showed increased brightness of the entire renal parenchyma; renal biopsy demonstrated prominent calcium deposition in the Bowman’s capsule and tubulointerstitial areas accompanied by collapsed glomeruli, severe interstitial fibrosis and tubular atrophy. Although the diagnosis was nephrocalcinosis, no underlying conditions were found. Despite the management of chronic kidney disease-mineral bone disorder and nutritional therapy, the patient developed uremia and initiated maintenance hemodialysis approximately two years after the first visit. Kidney disorders are commonly observed in patients with eating disorders and may occasionally lead to end-stage kidney disease. However, detailed investigations are few, especially regarding the histopathological conditions of these patients, and the precise mechanisms remain unclear. Nephrocalcinosis can cause end-stage kidney disease if extensive, as observed in the present case.

Abstract Introduction Cognitive impairment (CI) is common in both end‐stage kidney disease (ESKD) and alcohol‐related liver cirrhosis. The aim of this study was to assess the prevalence and patterns of CI in patients awaiting kidney and liver transplantation, and to identify its determinants. Methods In this cross‐sectional, prospective study, 31 consecutive patients with ESKD and 31 consecutive patients with alcohol‐related liver cirrhosis, all currently on transplant waiting lists, were screened for cognitive decline using the Addenbrooke's Cognitive Examination. Medical history, demographics, and laboratory test results were also collected. Results The prevalence of CI among patients with ESKD and alcohol‐related liver cirrhosis was 26% and 90%, respectively. In both groups, memory was the most affected cognitive domain, along with verbal fluency in patients with ESKD, and visuospatial abilities in patients with alcoholic cirrhosis. The most statistically significant increase in the prevalence of CI was found in patients with lower educational attainment, in both alcohol‐related liver cirrhosis and ESKD populations as well as in older patients with alcoholic cirrhosis. Furthermore, better cognitive functioning in ESKD patients was associated with higher levels of total lymphocyte count and alanine transaminase (ALT), and in alcohol‐related liver cirrhosis patients with higher levels of ALT and aspartate transaminase. A nonsignificant trend toward lower memory domain scores was also observed with increasing ammonia levels and increasing severity of liver disease (higher Child–Pugh scores). Finally, suboptimal performance on the screening test was correlated with the severity of liver disease as assessed by the Model for End‐Stage Liver Disease Sodium (MELD‐Na), but not at the statistically significant level. Conclusions The prevalence of CI, especially in patients with alcohol‐related liver cirrhosis, is high and can be a significant clinical problem, negatively affecting the transplantation process. Routine screening tests in this group would contribute to the implementation of appropriate management, such as rehabilitation program or psychosocial treatments and facilitate the provision of specialized health care.

Abstract The objective of the present investigation was to compare the coronary angiography results in diabetic patients with and without end‐stage kidney disease (ESKD). We included prolonged diabetic patients with ESKD (93 patients) and without ESKD (control group, 126 patients). Angiography of the coronary arteries was performed on all patients. Our results revealed that the ESKD patients tended to have a higher degree of coronary artery stenosis in all parts of LAD (p = 0.001, 0.024, and 0.005), proximal and distal RCA (p = 0.013, and 0.008), and proximal and distal LCX artery (p = 0.001, 0.008) than non‐ESKD patients. Furthermore, we found that the ESKD group had higher significant coronary artery stenosis in the LAD artery (60.5% vs. 39.5%, p

Chimeric antigen receptor (CAR) T-cell therapy against B-cell maturation antigen is a new treatment modality for relapsed or refractory multiple myeloma (MM). Patients with kidney failure and MM were excluded from the pivotal CAR T-cell therapy clinical trials: KaRMMa (idecabtagene vicleucel) and CARTITUDE (ciltacabtagene autocleucel). The safety and efficacy of CAR T-cell therapy in patients with relapsed or refractory MM and kidney failure are limited to a few case reports using idecabtagene vicleucel. Here, we report the first 2 cases of ciltacabtagene autoleucel use in patients with kidney failure on maintenance hemodialysis and relapsed or refractory MM. Both patients achieved a hematologic response following ciltacabtagene autoleucel administration without serious adverse events. These findings suggest that ciltacabtagene autoleucel may be safe and effective in patients with relapsed or refractory MM and kidney failure. In this report, we review the available literature regarding the use of CAR T-cell therapy in patients with MM and kidney failure. We also discuss the modification of the lymphodepletion regimen in the kidney failure setting.

Over 782 000 individuals in the United States have end-stage kidney disease with about 72% of patients on dialysis, a life-sustaining treatment. Dialysis patients experience high mortality and frequent hospitalizations, at about twice per year. These poor outcomes are exacerbated at key time periods, such as the fragile period after transition to dialysis. In order to study the time-varying effects of modifiable patient and dialysis facility risk factors on hospitalization and mortality, we propose a novel Bayesian multilevel time-varying joint model. Efficient estimation and inference is achieved within the Bayesian framework using Markov chain Monte Carlo, where multilevel (patient- and dialysis facility-level) varying coefficient functions are targeted via Bayesian P-splines. Applications to the United States Renal Data System, a national database which contains data on nearly all patients on dialysis in the United States, highlight significant time-varying effects of patient- and facility-level risk factors on hospitalization risk and mortality. Finite sample performance of the proposed methodology is studied through simulations.

Introduction: This study aimed to develop and validate machine learning (ML) models based on serum Klotho for predicting end-stage kidney disease (ESKD) and cardiovascular disease (CVD) in patients with chronic kidney disease (CKD). Methods: Five different ML models were trained to predict the risk of ESKD and CVD at three different time points (3, 5, and 8 years) using a cohort of 400 non-dialysis CKD patients. The dataset was divided into a training set (70%) and an internal validation set (30%). These models were informed by data comprising 47 clinical features, including serum Klotho. The best-performing model was selected and used to identify risk factors for each outcome. Model performance was assessed using various metrics. Results: The findings showed that the least absolute shrinkage and selection operator regression model had the highest accuracy (C-index = 0.71) in predicting ESKD. The features mainly included in this model were estimated glomerular filtration rate, 24-h urinary microalbumin, serum albumin, phosphate, parathyroid hormone, and serum Klotho, which achieved the highest area under the curve (AUC) of 0.930 (95% CI: 0.897–0.962). In addition, for the CVD risk prediction, the random survival forest model with the highest accuracy (C-index = 0.66) was selected and achieved the highest AUC of 0.782 (95% CI: 0.633–0.930). The features mainly included in this model were age, history of primary hypertension, calcium, tumor necrosis factor-alpha, and serum Klotho. Conclusion: We successfully developed and validated Klotho-based ML risk prediction models for CVD and ESKD in CKD patients with good performance, indicating their high clinical utility.

Abstract Background Peritoneal fibrosis is the prevailing complication induced by prolonged exposure to high glucose in patients undergoing peritoneal dialysis. Methods To elucidate the molecular mechanisms underlying this process, we conducted an integrated analysis of the transcriptome and chromatin accessibility profiles of human peritoneal mesothelial cells (HMrSV5) during high-glucose treatment. Results Our study identified 2775 differentially expressed genes (DEGs) related to high glucose-triggered pathological changes, including 1164 upregulated and 1611 downregulated genes. Genome-wide DEGs and network analysis revealed enrichment in the epithelial–mesenchymal transition (EMT), inflammatory response, hypoxia, and TGF-beta pathways. The enriched genes included VEGFA, HIF-1α, TGF-β1, EGF, TWIST2, and SNAI2. Using ATAC-seq, we identified 942 hyper (higher ATAC-seq signal in high glucose-treated HMrSV5 cells than in control cells) and 714 hypo (lower ATAC-seq signal in high glucose-treated HMrSV5 cells versus control cells) peaks with differential accessibility in high glucose-treated HMrSV5 cells versus controls. These differentially accessible regions were positively correlated (R = 0.934) with the nearest DEGs. These genes were associated with 566 up- and 398 downregulated genes, including SNAI2, TGF-β1, HIF-1α, FGF2, VEGFA, and VEGFC, which are involved in critical pathways identified by transcriptome analysis. Integrated ATAC-seq and RNA-seq analysis also revealed key transcription factors (TFs), such as HIF-1α, ARNTL, ELF1, SMAD3 and XBP1. Importantly, we demonstrated that HIF-1α is involved in the regulation of several key genes associated with EMT and the TGF-beta pathway. Notably, we predicted and experimentally validated that HIF-1α can exacerbate the expression of TGF-β1 in a high glucose-dependent manner, revealing a novel role of HIF-1α in high glucose-induced pathological changes in human peritoneal mesothelial cells (HPMCs). Conclusions In summary, our study provides a comprehensive view of the role of transcriptome deregulation and chromosome accessibility alterations in high glucose-induced pathological fibrotic changes in HPMCs. This analysis identified hub genes, signaling pathways, and key transcription factors involved in peritoneal fibrosis and highlighted the novel glucose-dependent regulation of TGF-β1 by HIF-1α. This integrated approach has offered a deeper understanding of the pathogenesis of peritoneal fibrosis and has indicated potential therapeutic targets for intervention.

Abstract Background Recently, discussions have increasingly focused on “withdrawal from dialysis” among patients undergoing dialysis who experience severe brain dysfunction as post-stroke sequelae. In this context, the lack of understanding regarding functional prognosis after spontaneous intracerebral hemorrhage in patients undergoing hemodialysis becomes a particularly important issue. Therefore, we aimed to evaluate the functional prognosis of intracerebral hemorrhage in patients undergoing hemodialysis when life-saving was prioritized and dialysis was not withdrawn. Furthermore, we sought to identify factors influencing life and functional prognosis. Methods We retrospectively analyzed data of 100 consecutive hemodialysis patients who experienced spontaneous intracerebral hemorrhage between 2012 and 2021. The in-hospital mortality rates and modified Rankin Scale (mRS) and Functional Independence Measure (FIM) scores at discharge and 90 days after onset were examined. Results The mean age of the patients was 65.7 years, with 29% of them undergoing life-saving brain surgery. The mRS score at discharge was 0, 1, 2, 3, 4, 5, and 6 (indicating death) in 0, 1, 13, 9, 26, 20, and 31 cases, respectively. Among the 69 surviving patients, the median FIM score at discharge was 37 (19–81), with 14 patients having an FIM score of 18 (i.e., complete dependence). Patients who underwent life-saving brain surgery showed a higher median mRS score [5, interquartile range (IQR) 5–6] and a lower FIM score (18, IQR 18–22) at discharge compared with those who did not undergo the surgery. Patients discharged with mRS and FIM scores of 5 and 18, respectively, had the same functional status at 90 days. The Functional Outcome in Patients With Primary Intracerebral Hemorrhage (FUNC) score and intraventricular extension at admission were predictive of a mRS score ≥ 5 (area under the receiver operating characteristic curve = 0.92, p

Abstract Background Pulmonary hypertension (PH) is a complication of chronic kidney disease (CKD) that contributes to mortality. Sclerostin, a SOST gene product that reduces osteoblastic bone formation by inhibiting Wnt/β-catenin signaling, is involved in arterial stiffness and CKD-bone mineral disease, but scanty evidence to PH. This study explored the relationship between sclerostin and PH in CKD 5, pre-dialysis end-stage kidney disease (ESKD) patients. Methods This cross-sectional prospective observational cohort study included 44 pre-dialysis ESKD patients between May 2011 and May 2015. Circulating sclerostin levels were measured using an enzyme-linked immunosorbent assay. PH was defined as an estimated pulmonary artery systolic pressure > 35 mmHg on echocardiography. Results Patients with higher sclerostin levels ≥ 218.18pmol/L had echocardiographic structural cardiac abnormalities, especially PH (P

Abstract Background We devoted ourselves to proving that the initial transthoracic echocardiography score (TTES) had predictive significance for patients with continuous ambulatory peritoneal dialysis (CAPD). Methods In this retrospective analysis, 274 CAPD patients who had PD therapy were recruited sequentially. TTE exams were performed three months following the start of PD therapy. All patients were divided into two groups based on the strength of their TTES levels. TTES’s predictive value for CAPD patients was then determined using LASSO regression and Cox regression. Results During a median of 52 months, 46 patients (16.8%) died from all causes, and 32 patients (11.7%) died from cardiovascular disease (CV). The TTES was computed as follows: 0.109 × aortic root diameter (ARD, mm) − 0.976 × LVEF (> 55%, yes or no) + 0.010 × left ventricular max index, (LVMI, g/m2) + 0.035 × E/e’ ratio. The higher TTES value (≥ 3.7) had a higher risk of all-cause death (hazard ratio, HR, 3.70, 95% confidence index, 95%CI, 1.45–9.46, P = 0.006) as well as CV mortality (HR, 2.74, 95%CI 1.15–19.17, P = 0.042). Moreover, the TTES had an attractive predictive efficiency for all-cause mortality (AUC = 0.762, 95%CI 0.645–0.849) and CV mortality (AUC = 0.746, 95%CI 0.640–0.852). The introduced nomogram, which was based on TTES and clinical variables, exhibited a high predictive value for all-cause and CV mortality in CAPD patients. Conclusion TTES is a pretty good predictor of clinical outcomes, and the introduced TTES-based nomogram yields an accurate prediction value for CAPD patients.

Teguh Marfen Djajakusumah, Putie Hapsari, Prapanca Nugraha, Arrayyan Muhammad, Kiki Lukman Department of Surgery, Faculty of Medicine, Universitas Padjadjaran/Dr. Hasan Sadikin General Hospital, Bandung, IndonesiaCorrespondence: Kiki Lukman; Teguh Marfen Djajakusumah, Email kiki.lukman@unpad.ac.id; marfen.djajakusumah@unpad.ac.idBackground: End-stage kidney disease (ESKD) is associated with a tremendous financial burden. Data in Indonesia shows an increasing number of patients with ESKD taking hemodialysis as a routine procedure every year. Establishment and maintenance of vascular access are important in the management of ESKD. Vascular complications that often arise due to hemodialysis are common and one of the main reasons for hospitalization. Cannulation complications ranged from minor hematomas to acute bleeding from pseudoaneurysms that required emergency surgical procedures. This study aims to assess the different clinicopathological characteristics of ESKD patients with vascular access cannulation complications and the surgical management related to the complications.Materials and Methods: This research is a retrospective observational study. The research subjects in this study were ESKD patients in the vascular and endovascular surgery division of the tertiary hospital in West Java, Indonesia. There were 121 study subjects. Clinicopathological characteristics of vascular cannulation complications and surgical management are extracted from the medical record.Results: Three major vascular complications were ruptured pseudoaneurysms 64/121 (52.9%), impending rupture pseudoaneurysms 28/121 (23.1%), and pseudoaneurysms 21/121 (17.4%). Common surgical procedures were ligation of the draining vein 47/121 (38.8%), arterial primary repair 28/121 (23.1%), and arterial patch repair 18/121 (14.9%). There was a significant relationship between symptoms of bleeding in ruptured pseudoaneurysms and bulging masses in pseudoaneurysms (p = 0.001). There was a significant relationship between the diameter of the vascular mass, vascular defect size, and hematoma and the type of surgical procedure taken (p < 0.010).Conclusion: Ruptured, impending rupture, and pseudoaneurysms are major complications of vascular access in ESKD patients, and there was a significant relationship between the carried-out surgical procedure and the size of the vascular mass, defect, and hematoma.Plain Language Summary: Chronic kidney failure is a particular challenge in terms of health problems in Indonesia. With the increase in kidney failure patients, the number of dialysis patients in this country has also sharply increased because blood dialysis is the main management for end-stage kidney failure. Dialysis treatment does not mean it is 100% safe; various complications can arise from the blood dialysis procedure. Many of the complications that arise are caused by problems with the blood vessels that serve as access to the dialysis machine. In this research, we aim to study the characteristics of blood dialysis complications related to blood vessel access. This study was conducted at one of the largest national hospitals in Indonesia, precisely in West Java province, which is the most populated province in Indonesia. In this study, we involved 121 end-stage kidney failure patients. This study is very important to carry out considering that around 30% of chronic kidney failure patients that were hospitalized have complications from blood vessels. We hope that this research can be used further in determining the best procedure for providing venous access for dialysis with all the limitations faced by developing countries.Keywords: arteriovenous fistula, end-stage kidney disease, hemodialysis, pseudoaneurysm, vascular access

Abstract Background For patients on dialysis with poor quality of life and prognosis, dialysis withdrawal and subsequent transition to palliative care is recommended. This study aims to understand multi-stakeholder perspectives regarding dialysis withdrawal and identify their information needs and support for decision-making regarding withdrawing from dialysis and end-of-life care. Methods Participants were recruited through purposive sampling from eight dialysis centers and two public hospitals in Singapore. Semi-structured in-depth interviews were conducted with 10 patients on dialysis, 8 family caregivers, and 16 renal healthcare providers. They were held in-person at dialysis clinics with patients and caregivers, and virtually via video-conferencing with healthcare providers. Interviews were audio-recorded, transcribed, and thematically analyzed. The Ottawa Decision Support Framework’s decisional-needs manual was used as a guide for data collection and analysis, with two independent team members coding the data. Results Four themes reflecting perceptions and support for decision-making were identified: a) poor knowledge and fatalistic perceptions; b) inadequate resources and support for decision-making; c) complexity of decision-making, unclear timing, and unpreparedness; and d) internal emotions of decisional conflict and regret. Participants displayed limited awareness of dialysis withdrawal and palliative care, often perceiving dialysis withdrawal as medical abandonment. Patient preferences regarding decision-making ranged from autonomous control to physician or family-delegated choices. Cultural factors contributed to hesitancy and reluctance to discuss end-of-life matters, resulting in a lack of conversations between patients and providers, as well as between patients and their caregivers. Conclusions Decision-making for dialysis withdrawal is complicated, exacerbated by a lack of awareness and conversations on end-of-life care among patients, caregivers, and providers. These findings emphasize the need for a culturally-sensitive tool that informs and prepares patients and their caregivers to navigate decisions about dialysis withdrawal and the transition to palliative care. Such a tool could bridge information gaps and stimulate meaningful conversations, fostering informed and culturally aligned decisions during this critical juncture of care.

Background: Palliative care (PC) focuses on relieving pain and difficult symptoms rather than treating disease or delaying its progress. Palliative care views death as a natural process and allows patients to live the last phase of their existence in the best possible way, encouraging them to express their opinions and wishes for a good death. Interventions are advocated to control symptoms and distress and promote wellbeing and social functioning. A multidisciplinary approach to support patients receiving palliative care is encouraged. Objective: The aims of this study were to investigate the facilitators and barriers to PC in people with kidney disease from a nursing perspective and to explore predictive factors associated with nurse-perceived facilitators and barriers to PC in people with kidney disease. Design: This study is a survey that adopted a questionnaire created in 2021 with Delphi methology, which included 73 statements divided into 37 facilitators and 36 barriers to PC in patients with kidney disease, to be scored using a Likert scale. Participants and Measurements: Participants were obtained through the membership database of the European Dialysis and Transplant Nurses Association/European Renal Care Association (EDTNA/ERCA) of 2020. Inclusion criteria included being registered as a nurse, an EDTNA/ERCA member and understanding of the English language. The questionnaire was sent via email. Results: Three profiles of respondents were found: the first group was characterized by the highest agreement percentages of facilitators and with an average value of 53.7% in barriers; the second was characterized by a lower endorsement of facilitators and similar agreement to the first group for barriers; the third group had a high probability (>80%) of items endorsing both barriers and facilitators. Predictive variables were significantly associated with “Years in nephrology” and “macro geographic area”. Conclusions: This study demonstrates variation in PC practice across Europe. Some professionals identified fewer barriers to PC and appeared more confident when dealing with difficult situations in a patient’s care pathway, while others identified more barriers as obstacles to the implementation of adequate treatment. The number of years of nephrology experience and the geographical area of origin predicted how nurses would respond. This study was not registered.

Abstract Background Evidence of willingness to pay for kidney replacement therapy is scarce in low-middle-income countries, including Nigeria’s Formal Sector Social Health Insurance Programme. The study, therefore, assessed the willingness to pay for haemodialysis among chronic kidney disease patients in Abuja, Nigeria. Methods The study adopted a cross-sectional survey design. We used the contingent valuation method to estimate the maximum stated willingness to pay (WTP) for haemodialysis among end-stage kidney disease (ESKD) patients. We obtained informed written consent from respondents before data collection. The socio-demographic characteristics and willingness to pay data were summarized using descriptive statistics. We evaluated the mean differences in respondents’ WTP using Mann-Whitney and Kruskal-Wallis tests. All variables that had p

Abstract Background Despite several clinical trials, the use of corticosteroid therapy for treating immunoglobulin A nephropathy (IgAN) remains controversial. We aimed to describe the use of corticosteroid therapy combined with supportive therapy in Norwegian patients with IgAN who had progressed to end-stage kidney disease. Methods We conducted a retrospective cohort study using data from the Norwegian Renal Registry. Overall, 143 patients with primary IgAN who progressed to end-stage kidney disease were divided into two groups: the corticosteroid group, who had been treated with corticosteroids and supportive therapy, and the non-corticosteroid group, which had underwent only supportive therapy. The kidney function, time to end-stage kidney disease, and adverse effects were described. The observation period lasted from the diagnostic kidney biopsy until the initiation of kidney replacement therapy. Results Of the 143 included patients, 103 underwent supportive therapy alone, and 40 were treated with corticosteroids. Most patients (94%) were treated with renin-angiotensin-system blockade, and all patients reached end-stage kidney disease after a median of 5 years (interquartile range; 2–9 years). Time from diagnosis until end-stage kidney disease was similar in the two study groups (p = 0.98). During 6 months of corticosteroid therapy, median eGFR declined from 21 (interquartile range; 13–46) mL/min/1.73 m2 to 20 (interquartile range; 12–40) mL/min/1.73 m2, and median proteinuria decreased from 5.5 g/24 h to 3.0 g/24 h. Most patients (87.5%) treated with corticosteroids reported adverse events. In our linear regression analysis investigating the time to ESKD, we found that age (β = -0.079, p = 0.008) and proteinuria at diagnosis (β = -0.50, p = 0.01) exhibited statistically significant associations with a delay in the progression to ESKD. Conclusions In this cohort of Norwegian patients with IgAN, corticosteroid therapy did not affect the time from diagnosis until end-stage kidney disease among a cohort of patients who all reached end-stage kidney disease. The treatment was also associated with adverse effects.

Recent accumulating epidemiological evidence underlines the important role of environmental exposures on kidney diseases. Among environmental exposures, this study addresses “Green space,” which has been recognized as one of the major environmental exposures at the population level. We review a total of seven epidemiological studies currently published on greenness and kidney disease. We also discuss knowledge gaps in the epidemiological evidence in relation to study design, greenness exposure index, emerging kidney outcomes, and inequalities. With an increase in public attention regarding environmental risks and climate change, an improved understanding of the beneficial effects of green space can play an important role in promoting kidney health.

Introduction: Despite the pivotal role of hepcidin in the development of anemia among the patients with chronic kidney disease (CKD), the association between serum hepcidin levels and CKD progression has been never investigated. We here hypothesized that elevation in serum hepcidin levels might be associated with the risk of incident end-stage kidney disease (ESKD) among the patients with pre-dialysis CKD. Methods: A total of 2,109 patients with pre-dialysis CKD at stages 1 to pre-dialysis 5 were categorized into the quartiles by serum hepcidin levels. The study outcome was incident ESKD. The median duration of follow-up was 7.9 years. Results: The analysis of the baseline characteristics revealed that unfavorable clinical features were in general associated with higher serum hepcidin levels. The cumulative incidence of ESKD was significantly differed by serum hepcidin levels, with the highest incidence in the 4th quartile (p < 0.001, by log-rank test). Cox regression analysis demonstrated that, compared to the 1st quartile, the risk of incident ESKD is significantly increased in the 4th quartile (adjusted hazard ratio 1.372, 95% confidence interval 1.070–1.759). Penalized spline curve analysis illustrated a linear, positive correlation between serum hepcidin levels and the risk of incident ESKD. Subgroup analyses revealed that the association is significantly more prominent in the patients with advanced CKD (i.e., estimated glomerular filtration rate

Objective and design: Immunoglobulin A nephropathy (IgAN) is a kidney disease characterized by the accumulation of IgA deposits in the glomeruli of the kidney, leading to inflammation and damage to the kidney. The inflammatory markers involved in IgAN remain to be defined. Gene expression analysis platforms, such as the NanoString nCounter system, are promising screening and diagnostic tools, especially in oncology. Still, their role as a diagnostic and prognostic tool in IgAN remains scarce. In this study, we aimed to validate the use of NanoString technology to identify potential inflammatory biomarkers involved in the progression of IgAN. Subjects: A total of 30 patients with biopsy-proven IgAN and 7 cases of antineutrophil cytoplasmic antibody (ANCA)-associated pauci-immune glomerulonephritis were included for gene expression measurement. For the immunofluorescence validation experiments, a total of 6 IgAN patients and 3 controls were included. Methods: Total RNA was extracted from formalin-fixed paraffin-embedded kidney biopsy specimens, and a customized 48-plex human gene CodeSet was used to study 29 genes implicated in different biological pathways. Comparisons in gene expression were made between IgAN and ANCA-associated pauci-immune glomerulonephritis patients to delineate an expression profile specific to IgAN. Gene expression was compared between patients with low and moderate risk of progression. Genes for which RNA expression was associated with disease progression were analyzed for protein expression by immunofluorescence and compared with controls. Results: IgAN patients had a distinct gene expression profile with decreased expression in genes IL-6, INFG, and C1QB compared to ANCA patients. C3 and TNFRSF1B were identified as potential biomarkers for IgAN progression in patients early in their disease course. Protein expression for those 2 candidate genes was upregulated in IgAN patients compared to controls. Expression of genes implicated in fibrosis (PTEN, CASPASE 3, TGM2, TGFB1, IL2, and TNFRSF1B) was more pronounced in IgAN patients with severe fibrosis compared to those with none. Conclusions: Our findings validate our NanoString mRNA profiling by examining protein expression levels of two candidate genes, C3 and TNFRSF1B, in IgAN patients and controls. We also identified several upregulated mRNA transcripts implicated in the development of fibrosis that may be considered fibrotic markers within IgAN patients. [ABSTRACT FROM AUTHOR]

This study aims to examine the prevalence and outcomes of end-stage kidney disease (ESKD) among systemic lupus erythematosus (SLE) patients. SLE patients identified from the national administrative datasets were linked to the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) to identify the ESKD cases. Period prevalence of ESKD among SLE patients was calculated. The risk of developing ESKD by ethnicity was explored with Cox Proportional Hazards model. The adjusted hazard ratio (HR) of all-cause mortality for Māori, Pacific, Asian compared to European/others was estimated. Of the 2837 SLE patients, 210 (7.4%) developed ESKD. The average period prevalence of ESKD among SLE patients was 5.7%. Men had twice the prevalence rate of ESKD than women (10.0% vs 5.2%). Māori and Pacific had higher prevalence rate than Asian and European/others (9.4%, 9.8% vs 4.4% and 3.8%). The adjusted HR of developing ESKD for men compared to women was 3.37 (95% CI 1.62–7.02). The adjusted HR of developing ESKD for Māori and Pacific compared to European/others was 4.63 (95% CI 1.61–13.29) and 4.66 (95% CI 1.67–13.00), respectively. Compared to European/others, Māori had an HR of 2.17 (95% CI 1.18–4.00) for all-cause mortality. SLE patients had a high prevalence rate of ESKD. Men, Māori, and Pacific patients with SLE were more likely to develop ESKD. Māori patients with ESKD had poorer survival than other patients. Interventions are needed to reduce the risk of ESKD and to improve the survival of ESKD patients for the disadvantaged groups. [ABSTRACT FROM AUTHOR]

Introduction: Rural areas face significant disparities in dialysis care compared to urban areas due to limited access to dialysis facilities, longer travel distances, and a shortage of healthcare professionals. The objective of this study was to conduct a national examination of rural-urban differences in quality of dialysis care offered across counties in the USA. Methods: Data were gathered from Medicare-certified dialysis facilities in 2020 from the Centers for Medicare and Medicaid Services website. To identify high-need counties, county-level estimated crude prevalence of diabetes in adults was obtained from the 2022 CDC PLACES data portal. Our analysis reviewed 3,141 counties in the USA. The primary outcome measured was whether the county had a dialysis facility. Among those counties that had a dialysis facility, additional outcomes were the average star rating, whether peritoneal dialysis was offered, and whether home dialysis was offered. Results: The type of services offered by dialysis facilities varied significantly, with peritoneal dialysis being the most commonly offered service (50.8%), followed by home hemodialysis (28.5%) and late-shift services (16.0%). These service availabilities are more prevalent in urban facilities than in rural facilities. The Centers for Medicare and Medicaid Services Five Star Quality ratings were quite different between urban and rural facilities, with 40.4% of rural facilities having a ranking of five, compared to 27.1% in urban. Conclusion: The majority of rural counties lack a single dialysis facility. Counties with high rates of chronic kidney disease, diabetes, and blood pressure, deemed high need, were less likely to have a highly rated dialysis facility. The findings can be used to further inform targeted efforts to increase diabetes educational programming and design appropriate interventions to those residing in rural communities and high-need counties who may need it the most.

Background: Palliative care (PC) focuses on relieving pain and difficult symptoms rather than treating disease or delaying its progress. Palliative care views death as a natural process and allows patients to live the last phase of their existence in the best possible way, encouraging them to express their opinions and wishes for a good death. Interventions are advocated to control symptoms and distress and promote wellbeing and social functioning. A multidisciplinary approach to support patients receiving palliative care is encouraged. Objective: The aims of this study were to investigate the facilitators and barriers to PC in people with kidney disease from a nursing perspective and to explore predictive factors associated with nurse-perceived facilitators and barriers to PC in people with kidney disease. Design: This study is a survey that adopted a questionnaire created in 2021 with Delphi methology, which included 73 statements divided into 37 facilitators and 36 barriers to PC in patients with kidney disease, to be scored using a Likert scale. Participants and Measurements: Participants were obtained through the membership database of the European Dialysis and Transplant Nurses Association/European Renal Care Association (EDTNA/ERCA) of 2020. Inclusion criteria included being registered as a nurse, an EDTNA/ERCA member and understanding of the English language. The questionnaire was sent via email. Results: Three profiles of respondents were found: the first group was characterized by the highest agreement percentages of facilitators and with an average value of 53.7% in barriers; the second was characterized by a lower endorsement of facilitators and similar agreement to the first group for barriers; the third group had a high probability (>80%) of items endorsing both barriers and facilitators. Predictive variables were significantly associated with "Years in nephrology" and "macro geographic area". Conclusions: This study demonstrates variation in PC practice across Europe. Some professionals identified fewer barriers to PC and appeared more confident when dealing with difficult situations in a patient's care pathway, while others identified more barriers as obstacles to the implementation of adequate treatment. The number of years of nephrology experience and the geographical area of origin predicted how nurses would respond. This study was not registered. [ABSTRACT FROM AUTHOR]

Background: We conducted a retrospective epidemiological study about the prevalence of stage 5 chronic kidney disease (CKD) in a high-income district, comparing some demographic characteristics and outcomes of those patients who had nephrological consultations and those who had not. Results: In a district of 400,000 adult subjects in 2020, 925 patients had an estimated glomerular filtration rate (eGFR) under 15 mL/min and CKD. In the same period, 747 (80.4%) patients were assessed by nephrologists, while 178 (19.6%) were not. Age (88 vs. 75, p < 0.0001), female gender (66.3% vs. 47%, p < 0.001), and eGFR (12 vs. 9 mL/min, p < 0.001) were significantly different in the patients assessed by a nephrologist as compared those who did not have nephrological care. Furthermore, unfollowed CKD patients had a significantly higher death rate, 83.1% versus 14.3% (p < 0.0001). Conclusions: About 20% of ESKD patients did not receive a nephrologist consultation. Older people and women were more likely not to be referred to nephrology clinics. Unfollowed patients with stage 5 CKD had a significantly higher death rate. [ABSTRACT FROM AUTHOR]

Individuals with end-stage kidney disease (ESKD) face higher cerebrovascular risk. Yet, the impact of peripheral vascular disease (PVD) and kidney transplantation (KTx) on hospitalization rates for cerebral infarction and hemorrhage remains underexplored. Analyzing 2,713,194 ESKD hospitalizations (2005–2019) using the National Inpatient Sample, we investigated hospitalization rates for ischemic and hemorrhagic cerebrovascular diseases concerning ESKD, PVD, KTx, or their combinations. Patients hospitalized with cerebral infarction due to thrombosis/embolism/occlusion (CITO) or artery occlusion resulting in cerebral ischemia (AOSI) had higher rates of comorbid ESKD and PVD (4.17% and 7.29%, respectively) versus non-CITO or AOSI hospitalizations (2.34%, p < 0.001; 2.29%, p < 0.001). Conversely, patients hospitalized with nontraumatic intracranial hemorrhage (NIH) had significantly lower rates of ESKD and PVD (1.64%) compared to non-NIH hospitalizations (2.34%, p < 0.001). Furthermore, hospitalizations for CITO or AOSI exhibited higher rates of KTx and PVD (0.17%, 0.09%, respectively) compared to non-CITO or AOSI hospitalizations (0.05%, p = 0.033; 0.05%, p = 0.002). Patients hospitalized with NIH showed similar rates of KTx and PVD (0.04%) versus non-NIH hospitalizations (0.05%, p = 0.34). This nationwide analysis reveals that PVD in ESKD patients is associated with increased hospitalization rates with cerebral ischemic events and reduced NIH events. Among KTx recipients, PVD correlated with increased hospitalizations for ischemic events, without affecting NIH. This highlights management concerns for patients with KTx and PVD.

Keratins are the main components of the cell cytoskeleton of epithelial cells. Epithelial cells under stressful stimuli react by modifying their keratin expression pattern. Glomerular diseases are pathological conditions that may lead to loss of kidney function if not timely diagnosed and treated properly. This study aims to examine glomerular and tubular keratin expression in podocytopathies, ANCA-associated vasculitis, and IgA nephropathy and how this expression correlates to clinical outcomes. We included 45 patients with podocytopathies (minimal change disease and focal segmental glomerulosclerosis), ANCA-associated vasculitis, and IgA nephropathy, with or without crescentic lesions, and healthy controls. All tissues were assessed by photon microscopy and immunohistochemistry. Biopsy sections were examined for keratins 7, 8, 18, and 19 expression in the glomerular and tubulointerstitial areas separately. Moreover, we examined how keratin expression was correlated with long-term kidney function outcomes. All four studied keratins had significantly increased glomerular expression in patients with ANCA vasculitis compared to controls and MCD patients. Tubular expression of keratins 7, 8, and 19 was related to kidney outcome in all groups. Patients with crescents had higher expression of all keratins in both glomeruli and tubulointerstitium. The presence of tubular atrophy, interstitial fibrosis, mesangial hyperplasia, and interstitial inflammation did not affect keratin expression. Keratins, an abundant component of renal epithelial cells, have the potential to be featured as a biomarker for kidney function prognosis in patients with glomerular diseases. [ABSTRACT FROM AUTHOR]

- Abstract
In 2019, the management of end-stage kidney disease (ESKD) shifted away from "Fistula First" (FF) to "ESKD Life-Plan: Patient Life-Plan First then Access Needs." Indeed, some patients exhibit such excessive comorbidity that even relatively minor vascular surgery may be complicated. The purpose of this study was to retrospectively assess complications and mortality (and delineate operative futility) in patients undergoing arteriovenous fistula (AVF) creation in the FF era. Consecutive AVFs created in a single institution before 2021 were retrospectively reviewed. Operative futility was defined as never-accessed fistula, no initiation of dialysis, failure of access maturation (despite secondary intervention), hemodialysis access-induced distal ischemia requiring ligation, early loss of secondary patency, and/or patient mortality within the first 6 postoperative months. A total of 401 AVFs were created including radial-cephalic (44%), brachial-cephalic (41%), and brachial-basilic (15%) constructions. Patients exhibited a mean age of 69 ± 15 years; 63% were male, and most (74%) were already being hemodialyzed at the time of fistula creation. Forty-five patients (11%) suffered a cardiac event, and five patients died (1%) within 90 days of their access surgery. Perioperative cardiac events were significantly more common after age 80 (19% vs 8%; P =.004); age >80 years was an independent predictor of major 90-day complications (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.04-3.39; P =.036) and the sole independent predictor of major morbidity defined as cardiopulmonary complications, stroke, or death within the first year (OR, 2.01; 95% CI, 1.24-3.25; P =.004). Operative futility was encountered in 52% of the cohort (n = 208 patients): 40% (n = 160) of primary AVFs failed to mature despite assistance, 19% (n = 77) had lost secondary patency by 6 months, 13% of patients (n = 53) were never started on dialysis after access creation, 4% (n = 16) were dead by 6 months, 2% of AVFs (n = 10) matured but were never accessed, and 2% (n = 9) required ligation for hemodialysis access-induced distal ischemia. Not surprisingly, the sole independent protector against operative futility was that catheter-based dialysis had been established prior to AVF creation (OR, 0.36; 95% CI, 0.22-0.59; P <.01). Approximately 50% of primary AVF operations performed in the aggressive FF era were deemed futile. Octogenarians were particularly prone to futility and complications during this era. A paradigm shift, from FF to an "ESKD Life-Plan" will, hopefully, more thoughtfully match vascular access strategies to individual patient needs. [ABSTRACT FROM AUTHOR]

Introduction: This retrospective study examined the relationship between the Glasgow Prognostic Score (GPS) at hemodialysis (HD) initiation and overall/cardiovascular mortality. Methods: A total of 264 patients starting HD between 2014 and 2015 at a single center were studied. Follow‐up persisted until therapy change, death, or study end (December 31, 2021), with a median of 6.8 years. Results: Patients with a higher GPS more frequently had emergent HD initiation and showed increased eGFR at initiation. During follow‐up, 60% of patients died, with cardiovascular disease being the leading cause. Univariate analysis revealed a significant difference in median survival time across GPS classes. Cox proportional hazard models confirmed a significant association between GPS and mortality. Conclusions: We report a significant association between GPS at HD initiation and mortality. GPS may prove useful as a prognostic tool for identifying high‐risk patients, underscoring the need for future research to validate these findings and explore the potential of GPS‐based interventions.

Introduction: Mortality following hemodialysis initiation may influence the decision to initiate hemodialysis in elderly patients. Our objective is to demonstrate mortality following hemodialysis initiation in elderly patients (≥70 years) and to derive a prediction risk score based on clinical and laboratory indicators to determine risk of all-cause mortality in patients aged ≥80 years. Methods: We identified elderly patients (≥70 years) who initiated maintenance hemodialysis between January 2005 and December 2016 using data from the Thai Renal Replacement Therapy (TRT) registry. The mortality rate was determined based on age categories. A predictive risk score for all-cause mortality was created for 4,451 patients aged ≥80 years by using demographics, laboratory values, and interview-based parameters. Using a flexible parametric survival analysis, we predicted mortality 3 months, 6 months, 1 year, 5 years, and 10 years after hemodialysis initiation. Results: 17,354 patients (≥70 years) were included, mean age 76.9 ± 5.1 years, 46.5% male, and 6,309 (36.4%) died. Patients aged <80 years had a median survival time of 110.6 months. A 9-point risk score was developed to predict mortality in patients aged ≥80 years: age >85 years, male, body mass index <18.5 kg/m
2 , hemoglobin <10.0 g/dL, albumin <3.5 g/dL, substantial assistance required in daily living (1 point each), and Karnofsky Performance Status (KPS) score <50 (3 points). C-statistic of 0.797 indicated high model discrimination. Internal validation demonstrated good agreement between observed and anticipated mortalities. Conclusions: Hemodialysis is appropriate for patients aged 70–80 years. A risk score for mortality in patients aged ≥80 years has been developed. The score is based on seven readily obtainable and evaluable clinical characteristics. [ABSTRACT FROM AUTHOR]- Published

Nephrogenic calciphylaxis is associated with multiple risk factors including long-term dialysis dependence, hyperphosphatemia, hypercalcemia, parathyroid hormone derangements, vitamin K deficiency, obesity, diabetes mellitus, warfarin use, and female sex. Bariatric surgery is known to cause altered absorption, leading to mineral and hormonal abnormalities in addition to nutritional deficiency. Prior case reports on calciphylaxis development following bariatric surgery have been published, though are limited in number. We report a case series of five bariatric patients from a single institution who developed nephrogenic calciphylaxis between 2012 and 2018. These patients had a history of bariatric surgery, and at the time of calciphylaxis diagnosis, demonstrated laboratory abnormalities associated with surgery including hypercalcemia (n = 3), hyperparathyroidism (n = 2), hypoalbuminemia (n = 5), and vitamin D deficiency (n = 5), in addition to other medication exposures such as vitamin D supplementation (n = 2), calcium supplementation (n = 4), warfarin (n = 2), and intravenous iron (n = 1). Despite the multifactorial etiology of calciphylaxis and the many risk factors present in the subjects of this case series, we submit that bariatric surgery represents an additional potential risk factor for calciphylaxis directly stemming from the adverse impact of malabsorption and overuse of therapeutic supplementation. We draw attention to this phenomenon to encourage early consideration of calciphylaxis in the differential for painful skin lesions arising after bariatric surgery as swift intervention is essential for these high-risk patients.

Background and Objectives: IgA nephropathy (IgAN), the most common primary glomerulonephritis, has been extensively studied for renal outcomes, with limited data on patient survival, particularly in Eastern Europe. We aimed to investigate the long-term survival rate of patients with IgAN and the associated risk factors in an Eastern European cohort. Materials and Methods: We conducted a retrospective analysis of 215 IgAN patients (median age 44, 71% male) diagnosed at a Romanian tertiary center between 2010 and 2017. We assessed clinical and pathological attributes, including the Charlson comorbidity index, the prevalence of diabetes, renal function, and treatment with renin-angiotensin-system inhibitors (RASIs). Results: Over a median 7.3-year follow-up, 20% of patients died, mostly due to cardiovascular diseases. Survival rates at 1, 5, and 10 years were 93%, 84%, and 77%, respectively. Deceased patients had higher Charlson comorbidity index scores, greater prevalence of diabetes, and poorer renal function. They were less frequently treated with RASIs and more frequently reached end-stage kidney disease (ESKD). Conclusions: We report a 20% mortality rate in our Eastern European IgAN cohort, primarily due to cardiovascular diseases. Death correlates with increased age, comorbidity burden, decreased renal function at diagnosis, and the absence of RASI use. RASI treatment may potentially improve survival, highlighting its importance in managing IgAN. [ABSTRACT FROM AUTHOR]

Background: Despite several clinical trials, the use of corticosteroid therapy for treating immunoglobulin A nephropathy (IgAN) remains controversial. We aimed to describe the use of corticosteroid therapy combined with supportive therapy in Norwegian patients with IgAN who had progressed to end-stage kidney disease. Methods: We conducted a retrospective cohort study using data from the Norwegian Renal Registry. Overall, 143 patients with primary IgAN who progressed to end-stage kidney disease were divided into two groups: the corticosteroid group, who had been treated with corticosteroids and supportive therapy, and the non-corticosteroid group, which had underwent only supportive therapy. The kidney function, time to end-stage kidney disease, and adverse effects were described. The observation period lasted from the diagnostic kidney biopsy until the initiation of kidney replacement therapy. Results: Of the 143 included patients, 103 underwent supportive therapy alone, and 40 were treated with corticosteroids. Most patients (94%) were treated with renin-angiotensin-system blockade, and all patients reached end-stage kidney disease after a median of 5 years (interquartile range; 2–9 years). Time from diagnosis until end-stage kidney disease was similar in the two study groups (p = 0.98). During 6 months of corticosteroid therapy, median eGFR declined from 21 (interquartile range; 13–46) mL/min/1.73 m
2 to 20 (interquartile range; 12–40) mL/min/1.73 m2 , and median proteinuria decreased from 5.5 g/24 h to 3.0 g/24 h. Most patients (87.5%) treated with corticosteroids reported adverse events. In our linear regression analysis investigating the time to ESKD, we found that age (β = -0.079, p = 0.008) and proteinuria at diagnosis (β = -0.50, p = 0.01) exhibited statistically significant associations with a delay in the progression to ESKD. Conclusions: In this cohort of Norwegian patients with IgAN, corticosteroid therapy did not affect the time from diagnosis until end-stage kidney disease among a cohort of patients who all reached end-stage kidney disease. The treatment was also associated with adverse effects. [ABSTRACT FROM AUTHOR]- Published

Introduction: An arteriovenous fistula (AVF) in patients with end‐stage kidney disease (ESKD) can influence flow states. We sought to evaluate if assessment of aortic stenosis (AS) by transthoracic echocardiographic (TTE) differs in the presence of AVF compared to other dialysis accesses in patients on dialysis. Methods: We identified consecutive ESKD patients on dialysis and concomitant AS from a single center between January 2000 and March 2021. We analyzed TTE parameters of AS severity (velocities, gradients, aortic valve area [AVA]) and hemodynamics (cardiac output [CO], valvuloarterial impedance [Zva]) and compared AS parameters in patients with AVF versus other dialysis access. Results: The cohort included 94 patients with co‐prevalent ESKD and AS; mean age 66 years, 71% male; 43% Black, 24% severe AS. Dialysis access: 53% AVF, 47% others. In the overall cohort, no significant differences were noted between AVF versus non‐AVF in AVA/CO/Zva, but with notable subgroup differences. In mild AS, CO was significantly higher in AVF versus non‐AVF (6.3 vs. 5.2 L/min; p =.04). In severe AS, Zva was higher in the AVF versus non‐AVF (4.6 vs. 3.6 mm Hg/mL/m2). With increasing AS severity in the AVF group, CO decreased, coupled with increase in Zva, likely counterbalancing the net hemodynamic impact of the AVF. Conclusion: Among ESKD patients with AS, TTE parameters of flow states and AS severity differed in those with AVF versus other dialysis accesses and varied with progression in severity of AS. Future longitudinal assessment of hemodynamic parameters in a larger cohort of co‐prevalent ESRD and AS would be valuable. [ABSTRACT FROM AUTHOR]

Background: The clinical significance of mesangial immunoglobulin (Ig) M deposition in IgA nephropathy (IgAN) has been less explored and remains a topic of debate. Therefore, our study aimed to investigate the prognostic value of mesangial IgM deposition in a long-term follow-up cohort of IgAN patients. Methods: A unicentric retrospective study was conducted on 93 consecutive IgAN patients (median age 41years, 68% male, eGFR 48.7mL/min, proteinuria 1.1g/g) from 2010 to 2015. They were followed until end-stage kidney disease (ESKD), death, or until the end of the study in January 2021, with a median follow-up of 7years. An independent pathologist evaluated the IgM immunofluorescence pattern, Oxford MEST-C score, and transmission electron microscopy (TEM) lesions following a comprehensive protocol. Results: In our cohort, 70% had mesangial IgM-positive deposits, while 30% were IgM-negative. Both groups were similar in age, sex, prevalence of arterial hypertension, Charlson comorbidity scores, kidney function (eGFR and proteinuria), pathology findings (Oxford MEST-C score, IgG and C3 immune deposition), and TEM analysis. Treatment with RASI and immunosuppression, and death rates were also comparable. However, 37% of IgM-positive patients progressed to ESKD, significantly higher than the 11% in the IgM-negative group. Univariate and multivariate Cox proportional hazards regression analyses identified lower eGFR, higher Oxford MEST-C score, and mesangial IgM deposits as independent factors associated with shorter kidney survival. Conclusions: Our study highlights mesangial IgM deposition as a potential risk factor for ESKD in patients with advanced IgAN, laying a foundation for further research in this area.

Objective: This clinical trial aimed to evaluate the effect of L-carnitine on serum levels of lipid biomarkers of oxidative stress in chronic hemodialysis patients. Methods: From a total of 90 patients with end-stage kidney disease enrolled in this trial, 87 patients completed the study. L-carnitine tablets (250 mg/T) dissolved in 30 mL water (25 mg/kg) were administered orally twice daily before meals for a period of 3 months in the intervention group (n=44). Instead, the controls (n=43) received placebo. Before and 12 weeks after treatment, serum levels of malondialdehyde (MDA), low-density lipoprotein (LDL), and other markers were measured. Results: The mean serum levels of MDA after hemodialysis (before L-carnitine therapy) were respectively 5.64±2.04 and 5.78±2.12 µmol/L in the intervention and control groups, respectively, which were not statistically different from the levels before hemodialysis (5.60±2.05 and 5.74±2.16 µmol/L, respectively, p>0.05). The reduction in MDA levels after L-carnitine therapy was significantly greater in the intervention group vs. controls (5.17±2.04 vs. 5.60±2.13 µmol/L, p<0.001). In addition, the reduction in LDL levels after treatment was significantly more evident in the intervention group compared with that in the controls (p<0.001). The dose consumption of erythropoietin decreased far more in the intervention group (from; 8000±520 to 3750±418 unite/week) than in the control group (from; 8000±318 to 6000±528) after 5 months of follow-up (p=0.029). Conclusion: Oral administration of L-carnitine in chronic hemodialysis patients may remarkably modulate lipid marker levels of oxidative stress and reduce the dose consumption of erythropoietin without any side effects.
