INTRODUCTION: Human nephrogenesis is typically completed by 36 weeks gestation; however, it is impacted by preterm birth. Early studies suggested that nephrogenesis persisted for ≤40 postnatal days in preterm infants. However, the postmenstrual age (PMA) of the preterm infants who survived >40 days was uncertain. In this study, we sought to reexamine postnatal kidney development in preterm infants surviving >40 days. METHODS: Human kidney samples were obtained from an institutional biobank...

Cystinosis is a rare, inherited, lysosomal storage disorder characterized by the progressive accumulation of intralysosomal cystine and subsequent organ and tissue damage. The kidneys are the first and most severely impacted organ. Although cystinosis was once considered a fatal pediatric disease, patients with cystinosis are living well into adulthood with advances in medical care, including kidney transplant and early and continuous use of cysteamine therapy. This increase in life expectancy has revealed an extrarenal phenotype of cystinosis that emerges in adolescence and adulthood, affecting nearly all body systems, including the endocrine and reproductive systems...

INTRODUCTION: IgA nephropathy's (IgAN's) MEST-C classification relationship with complement activation is still not fully understood because of limited and conflicting evidence. Our study aimed to delineate this relationship through a systematic review. METHODS: We adhered to the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines and conducted a systematic review, utilizing databases like MEDLINE (PubMed), Embase, Scopus, and Cochrane from January 2016 (year of updated MEST-C classification) to January 2023...

INTRODUCTION: Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by Mycobacterium tuberculosis in patients on PD and (ii) review cases of peritonitis due to M tuberculosis in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition...

INTRODUCTION: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have emerged as novel therapeutics to treat diabetic kidney disease (DKD). Although the beneficial effects of SGLT2i have been demonstrated, their target mechanisms on kidney function are unknown. The current study aimed to elucidate these mechanisms by studying SGLT2i-induced changes in the urinary proteome of persons with type 2 diabetes (T2D) and DKD. METHODS: A total of 40 participants with T2D were enrolled in a double-blinded randomized cross-over trial at the Steno Diabetes Center Copenhagen, Denmark...

INTRODUCTION: The prevalence of chronic kidney disease (CKD) in Australia varies substantially across reports. Using a large, nationally representative general practice data source, we determined the contemporary prevalence and staging of CKD in the Australian primary care. METHODS: We performed a retrospective, community-based observational study of 2,720,529 adults with ≥1 visit to a general practice participating in the MedicineInsight program and ≥1 serum creatinine measurement (with or without a urine albumin-to-creatinine ratio [UACR] measurement) between 2011 and 2020...

INTRODUCTION: Central aortic blood pressure (BP) could be a better risk predictor than brachial BP. This study examined whether invasively measured aortic systolic BP improved outcome prediction beyond risk prediction by conventional cuff-based office systolic BP in patients with and without chronic kidney disease (CKD). METHODS: In a prospective, longitudinal cohort study, aortic and office systolic BPs were registered in patients undergoing elective coronary angiography (CAG)...

INTRODUCTION: The potential value of serum galactomannan index (GMI) in monitoring treatment response in patients with fungal peritonitis who are receiving peritoneal dialysis (PD) was assessed in the present study. METHODS: The study included all Thailand fungal PD-related infectious complications surveillance (MycoPDICS) DATA study participants who had timely PD catheter removal and availability of both baseline and ≥2 subsequent serum GMI measurements after starting antifungal therapy (if available)...

INTRODUCTION: A lengthy donor evaluation process hinders living donor kidney transplantation (LDKT). At The Ottawa Hospital, 1-day evaluation process was recently developed, with a goal to accelerate the determination of donor suitability. The major objective of this study was to solicit feedback from donor candidates and key stakeholders who participated in the 1-day living kidney donor evaluation process, to determine the program's acceptability and factors influencing its implementation elsewhere...

INTRODUCTION: C3 glomerulopathy (C3G) is an ultrarare renal disease characterized by deposition of complement component C3 in the glomerular basement membrane (GBM). Rare and novel genetic variation in complement genes and autoantibodies to complement proteins are commonly identified in the C3G population and thought to drive the underlying complement dysregulation that results in renal damage. However, disease heterogeneity and rarity make accurately defining characteristics of the C3G population difficult...

INTRODUCTION: This study aimed to evaluate the association between the use of remote patient monitoring (RPM) in patients on automated peritoneal dialysis (APD) and the Standardized Outcomes in Nephrology in peritoneal dialysis (SONG-PD) clinical outcomes. METHODS: A prospective and multicenter cohort study was conducted on patients with advanced chronic kidney disease on APD, recruited at 16 Spanish Hospitals, between June 1 and December 31, 2021. Patients were divided into 2 cohorts, namely patients on APD with RPM (APD-RPM) and patients on APD without RPM...

INTRODUCTION: Autoantibodies to erythropoietin receptor (anti-EPOR antibodies) have been identified in patients with various kidney diseases. However, data in patients with type 2 diabetes (T2D) and chronic kidney disease (CKD) is limited. We assessed the prevalence of anti-EPOR antibodies and their association with clinical outcomes in this population. METHODS: The CREDENCE randomized patients with T2D and CKD to canagliflozin or placebo. Serum anti-EPOR antibodies, the exposure of interest, were measured using enzyme-linked immunosorbent assay...

INTRODUCTION: Galactose-deficient IgA1 (Gd-IgA1) plays a key role in the pathogenesis of IgA nephropathy (IgAN). Tonsillectomy has been beneficial to some patients with IgAN, possibly due to the removal of tonsillar cytokine-activated cells producing Gd-IgA1. To test this hypothesis, we used immortalized IgA1-producing cell lines derived from tonsils of patients with IgAN or obstructive sleep apnea (OSA) and assessed the effect of leukemia inhibitory factor (LIF) or oncostatin M (OSM) on Gd-IgA1 production...
