Neural epidermal growth factor-like 1 protein-positive membranous nephropathy in renal allografts: A series of 6 patients.

Membranous nephropathy (MN) is a major cause of nephrotic syndrome, and neural epidermal growth factor-like 1 protein (NELL1) is the second most common inciting antigen. An increasing number of exposures and diseases have been associated with NELL1 MN. There are limited data on NELL1 following kidney transplantation with only 1 previously reported case.

Incremental hemodialysis transition in veterans and nonveterans with kidney failure.

Purpose Of Review: Initiation of hemodialysis treatment with a thrice-weekly prescription is currently the standard of care irrespective of patients' residual kidney function (RKF), comorbidities, and preferences.

Recent Findings: Each year ∼12 000 Veterans with advanced kidney disease progress to end-stage kidney disease (ESKD) requiring dialysis and comprise greater than 10% of the US incident ESKD population. Dialysis is costly and is associated with impaired health-related quality of life (HRQOL) and high mortality risk, especially in the first year of treatment.

COVID-19 vaccine responses are influenced by distinct risk factors in naive and SARS-CoV-2 experienced hemodialysis recipients.

Background: Clinical risk factors of deficient immune responses to COVID-19 mRNA vaccination in SARS-CoV-2 naive hemodialysis recipients (HDR) have already been identified. Clinical factors influencing hybrid immunity induced by SARS-CoV-2 infection and vaccination in HDR have not been reported.

Methods: A comprehensive analysis of antibody (Ab) and T cell responses to two doses of BNT162b2 mRNA vaccination was performed in 103 HDR, including 75 SARS-CoV-2 naive and 28 experienced patients, and in 106 healthy controls (HC) not undergoing HD, including 40 SARS-CoV-2 naive and 66 experienced subjects.

Successful use of deceased donors with medically complex kidneys.

The number of patients waiting for kidney transplants from deceased organ donors continues to increase. In this context, non-transplantation of acceptable kidneys is especially regrettable. Here, we review successful transplantation of deceased donor kidneys with anatomic abnormalities, intrinsic kidney diseases, and other ostensibly problematic conditions.

Hyperkalemia management: a multidisciplinary expert panel's perspective on the role of new potassium binders.

Hyperkalemia is a potentially life-threatening condition frequently encountered in clinical practice, particularly among patients with chronic kidney disease, heart failure, diabetes, and hypertension and those undergoing treatment with renin-angiotensin-aldosterone system inhibitors (RAASi). The management of chronic and acute hyperkalemia is complex and requires timely intervention to prevent severe complications such as cardiac arrhythmias and sudden death. Traditional therapeutic approaches to chronic hyperkalemia, including dietary potassium restriction, use of diuretics, and administration of cation-exchange resins like sodium polystyrene sulfonate, often suffer from limitations like gastrointestinal side effects, variable efficacy, delayed onset of action, and RAASi treatment discontinuation.

PREVALENCE, Characteristics, and Awareness of Chronic Kidney Disease in Croatia: The EH-UH 2 Study.

. National surveys have reported variable prevalence of chronic kidney disease (CKD), due to differences in the characteristics of the population, study design, equations used for the estimated glomerular filtration rate (eGFR), and definitions. The EH-UH 2 survey is the first study evaluating CKD prevalence, characteristics, and awareness in Croatia.

Osteopontin and Clinical Outcomes in Hemodialysis Patients.

Background/objectives: Chronic kidney disease (CKD) and end-stage kidney disease (ESKD) are significant public health issues, with cardiovascular morbidity and mortality being the leading causes of death in hemodialysis patients. Osteopontin (OPN), a multifunctional glycoprotein, has emerged as a potential biomarker for vascular disease in CKD due to its role in inflammation, tissue remodeling, and calcification.

Methods: This cohort study included 1124 hemodialysis patients from the PROGREDIRE study, a registry involving 35 dialysis units in Southern Italy.

Clinical and Histopathological Findings in HIV-positive to HIV-positive Kidney Transplant Recipients.

Background: The spectrum of histological findings in transplanted kidneys from HIV-positive donors to HIV-positive recipients is relatively unexplored. This study describes the type and timing of histological diagnoses observed in this unique cohort.

Methods: Adequate biopsies were analyzed at implantation and posttransplant between September 2008 and May 2022.

Global burden of disease attributable to metabolic risk factors in adolescents and young adults aged 15-39, 1990-2021.

Background: Metabolic risk factors are a significant cause of global burden among adolescents and young adults, but there is a lack of attention to the burden attributable to these metabolic risk factors globally.

Aims: This study aims to provide comprehensive estimates of five important metabolic risk factors and the attributable disease burden in people aged 15-39 years from 1990 to 2021, based on the Global Burden of Disease Study (GBD) database.

Methods: Global total deaths and disability-adjusted life years (DALYs) were used to describe the burden attributable to five common metabolic risk factors, including high fasting plasma glucose (FPG), high low-density lipoprotein cholesterol (LDL-C), high systolic blood pressure (SBP), high body mass index (BMI), and kidney dysfunction, in adolescents and young adults.

Predictive utility of nomogram based on serum glucose-regulated protein 78 and kidney function for long-term kidney graft survival.

The estimated glomerular filtration rate (eGFR) at 1 year post-transplantation is a well-established predictor of long-term graft survival; however, its predictive accuracy needs improvement. We retrospectively analyzed data from 51 kidney transplant recipients at Kanazawa Medical University Hospital (January 2001-February 2015). Cox regression was used to identify risk factors for death-censored graft loss and create a nomogram to predict graft survival at 15 years post-transplantation.

A semi-permeable insert culture model for the distal part of the nephron with human and mouse tubuloid epithelial cells.

Tubuloids are advanced in vitro models obtained from adult human or mouse kidney cells with great potential for modelling kidney function in health and disease. Here, we developed a polarized human and mouse tubuloid epithelium on cell culture inserts, namely Transwell™ filters, as a model of the distal nephron with an accessible apical and basolateral side that allow for characterization of epithelial properties such as leak-tightness and epithelial resistance. Tubuloids formed a leak-tight and confluent epithelium on Transwells™ and the human tubuloids were differentiated towards the distal part of the nephron.

Senescence Biomarkers and Trajectories of Frailty and Physical Function After Kidney Transplantation.

Cellular senescence is a biological mechanism of aging and age-related diseases. The aim of this study was to examine whether senescence biomarkers are associated with frailty and physical function trajectories in patients undergoing kidney transplantation (KT). We also discussed the relationship between senescence biomarkers and KT function.

Trichodysplasia spinulosa post kidney transplant.

Trichodysplasia spinulosa is a rare dermatological condition caused by a virus that predominantly affects immunosuppressed individuals. In this patient population, including organ transplant recipients, it is essential to maintain a high index of suspicion for possible infectious causes of persistent dermatologic conditions. Early diagnosis can facilitate treatment and help avoid disease progression and complications.

Mitigating High-risk EBV and CMV Through Kidney Paired Donation: A Survey of Potential Donor and Recipient Candidates.

Background: High-risk cytomegalovirus (CMV) and Epstein-Barr virus (EBV) mismatches (ie, seropositive donors to seronegative recipients) among kidney transplant recipients lead to increased healthcare utilization, inferior allograft outcomes, and high mortality. We assessed the interest among prospective kidney donor and recipient candidates to participate in kidney paired donation (KPD) for averting CMV/EBV high-risk mismatches.

Methods: We surveyed 51 potential living donors and 102 kidney recipient candidates presenting for their evaluation visit at the University of Pittsburgh Medical Center between October 2022 and May 2023.

Correction Rates and Clinical Outcomes in Hospitalized Adults With Severe Hyponatremia: A Systematic Review and Meta-Analysis.

Importance: Hyponatremia treatment guidelines recommend limiting the correction of severe hyponatremia during the first 24 hours to prevent osmotic demyelination syndrome (ODS). Recent evidence suggests that slower rates of correction are associated with increased mortality.

Objective: To evaluate the association of sodium correction rates with mortality among hospitalized adults with severe hyponatremia.

Acute Kidney Injury in Deceased Organ Donors: Risk Factors And Impacts on Transplantation Outcomes.

Background: Acute kidney injury in deceased donors (D-AKI) is one of the common causes of donor kidney discard. The risk factors for D-AKI and its impact on kidney transplantation outcomes are not yet fully understood.

Methods: This single-center, retrospective cohort study included 388 donors referred between June 2021 and December 2022.

Haemolytic uremic syndrome as a cause of chronic kidney disease stage 5 in children is in retreat: results from the Polish Registry of Kidney Replacement Therapy in children (2000-2023).

Background: Haemolytic uremic syndrome (HUS) is a life-threatening disease with a historically poor prognosis in children receiving maintenance kidney replacement therapy (KRT). This study aimed to analyse the incidence and outcome of chronic kidney disease stage 5 (CKD5) due to Escherichia coli-HUS (STEC-HUS) and complement-mediated HUS (CM-HUS) in children, compared with controls with non-HUS CKD5 over the last 24 years.

Methods: The study included 1488 children undergoing KRT in Poland between 2000 and 2023.

BK polyomavirus nephropathy after heart transplantation: A case report.

Unlabelled: We present a case of BK polyomavirus (BKV) nephropathy (BKVN) after heart transplantation (HTx). The patient was a male with non-ischemic cardiomyopathy who received HTx at the age of 56 years [serum creatinine (sCre) at the time of HTx: 0.89 mg/dl].

Age-Related Differences in Rejection Rates, Infections, and Tacrolimus Exposure in Pediatric Kidney Transplant Recipients in the CERTAIN Registry.

Introduction: Data on age-related differences in rejection rates, infectious episodes, and tacrolimus exposure in pediatric kidney transplant recipients (pKTRs) on a tacrolimus-based immunosuppressive regimen are scarce.

Methods: We performed a large-scale analysis of 802 pKTRs from the Cooperative European Paediatric Renal Transplant Initiative (CERTAIN) registry from 40 centers in 14 countries. The inclusion criteria were a tacrolimus-based immunosuppressive regimen and at least 2 years of follow-up.
