Background: Individual kidney tubule biomarkers are associated with risks for chronic kidney disease (CKD) progression and mortality in persons with diabetes. Integrating multiple kidney biomarkers using a latent variable method of exploratory factor analysis could define distinct dimensions of kidney health, and their associations with adverse outcomes.

Methods: We conducted a factor analysis of 17 candidate urine and plasma biomarkers in 1,256 participants with diabetes and estimated glomerular filtration rate (eGFR) <60ml/min/1.

Background: Intercellular adhesion molecule-1 (ICAM-1) is a cell-surface protein that facilitates inflammation through leucocyte adhesion. Approximately 35% of Black individuals carry at least one copy of an missense variant (rs5491; p.K56M), which has been associated with increased risk of heart failure (HF) with preserved ejection fraction (HFpEF).

Objectives: To assess whether the effect of sarcopenia on neoadjuvant chemotherapy (NAC) toxicity is modified by borderline renal function (estimated glomerular filtration rate [eGFR] 40-65 mL/min) and whether sarcopenia and borderline renal function are independently associated with NAC toxicity risk.

Patients And Methods: All patients with muscle-invasive bladder cancer (MIBC) who underwent radical cystectomy (RC) between 2010 and 2022, with available cross-sectional imaging prior to NAC initiation, were included. Skeletal mass was measured from axial computed tomography images obtained at the level of the L3 vertebral body, using Aquarius Intuition software.

Key Points: Apolipoprotein L1 (APOL1) high-risk genotype had higher risk of 3-year GFR-related surrogate end points and long-term kidney failure than those with the low-risk genotype. No consistent difference in surrogate–clinical outcome associations by APOL1 genotype, supporting the use of surrogates in APOL1 kidney disease.

Background: Surrogate end points for the clinical outcome of kidney failure have been accepted by the US Food and Drug Administration.

Rationale & Objective: Vaccination for influenza is strongly recommended for people with chronic kidney disease (CKD) due to their immunocompromised state. Identifying risk factors for not receiving an influenza vaccine (non-vaccination) could inform strategies for improving vaccine uptake in this high-risk population.

Study Design: Longitudinal observational study.

Background: Prior studies associating acute kidney injury (AKI) with more rapid subsequent loss of kidney function had methodological limitations, including inadequate control for differences between patients who had AKI and those who did not.

Objective: To determine whether AKI is independently associated with subsequent kidney function trajectory among patients with chronic kidney disease (CKD).

Design: Multicenter prospective cohort study.

Immunoglobulin A nephropathy (IgAN) is the most common glomerulonephritis in the world. The etiology is unknown but a dysregulated T-cell immune response to viral, bacterial, and food antigens activating mucosal plasma cells to produce polymeric IgA has been proposed. No serological test exists to diagnosis IgAN.

C3 glomerulopathy (C3G) is a rare kidney disease that causes kidney dysfunction as a result of dysregulation of the complement system alternate pathway (AP). C3G encompasses 2 separate disorders, C3 glomerulonephritis and dense deposit disease. The presentation and natural history is variable and kidney biopsy is needed to confirm the diagnosis.

Background: Patients hospitalized with AKI have higher subsequent risks of heart failure, atherosclerotic cardiovascular events, and mortality than their counterparts without AKI, but these higher risks may be due to differences in prehospitalization patient characteristics, including the baseline level of estimated glomerular filtration rate (eGFR), the rate of prior eGFR decline, and the proteinuria level, rather than AKI itself.

Methods: Among 2177 adult participants in the Chronic Renal Insufficiency Cohort study who were hospitalized in 2013-2019, we compared subsequent risks of heart failure, atherosclerotic cardiovascular events, and mortality between those with serum creatinine-based AKI (495 patients) and those without AKI (1682 patients). We report both crude associations and associations sequentially adjusted for prehospitalization characteristics including eGFR, eGFR slope, and urine protein-creatinine ratio (UPCR).

Key Points: A nephrologist is more likely to recognize the presence of pathologic casts and dysmorphic red blood cells. Nephrologist-performed urine sediment analysis is also highly accurate in diagnosing acute tubular injury or glomerulonephritis when compared with kidney biopsy.

Introduction: Automated urine technology is becoming the standard for urinalysis microscopy.

While patients receiving dialysis therapy in the United States are more likely to develop cardiovascular disease (CVD) than those in Japan, direct comparisons of patients with predialysis chronic kidney disease (CKD) are rare. To study this, we compared various outcomes in patients with predialysis CKD using data from the Chronic Renal Insufficiency Cohort (CRIC) and CKD Japan Cohort (CKD-JAC) studies and determined mediators of any differences. Candidate mediators included left ventricular (LV) indices assessed by echocardiography.
