Aim: Chronic kidney disease is associated with increased risk of cardiovascular diseases (CVD). This meta-analysis aims to evaluate the efficacy and safety of aspirin administered for primary prevention of CVD in patients with chronic kidney disease.
Methods: PubMed, Scopus, Web of Science, CENTRAL and Clinicaltrials.gov were systematically searched from inception to 22 June 2023. Randomized controlled trials (RCTs) and cohort studies evaluating aspirin as primary prevention of CVD in chronic kidney disease were included. Meta-analysis was conducted using random-effects models.
Results: Overall, 11 studies (6 RCTs and 5 cohort studies) with 24,352 patients were included. The meta-analysis of RCTs indicated that aspirin was associated with lower risk of major adverse cardiovascular events [hazard ratio (HR): 0.79; 95% confidence intervals (CI): 0.64-0.97] and higher risk of major bleeding [risk ratio (RR): 1.35; 95% CI 1.15-1.58]. Incorporating observational evidence led to statistically non-significant findings in terms of risk of both cardiovascular events (pooled HR: 0.97; 95% CI 0.75-1.25; low certainty) and major bleeding (pooled RR: 1.21; 95% CI 0.99-1.48; moderate certainty). No statistically significant differences between aspirin and placebo were observed in the outcomes of mortality, coronary heart disease, stroke and renal events.
Conclusions: RCT evidence points to a possible benefit in cardiovascular event reduction from aspirin administration, at the cost of increased major bleeding risk. This finding was not confirmed when the existing observational evidence was incorporated. Further research should determine the most appropriate subpopulation of chronic kidney disease patients that would benefit the most from prophylactic aspirin therapy.
Registration: The study protocol has been prospectively registered and is publicly available from: https://doi.org/10.17504/protocols.io.261ged63jv47/v1 .

Background: Experience with icodextrin use in children on long-term peritoneal dialysis is limited. We describe international icodextrin prescription practices and their impact on clinical outcomes: ultrafiltration, blood pressure control, residual kidney function (RKF), technique and patient survival.
Methods: We included patients under 21 years enrolled in the International Pediatric Peritoneal Dialysis Network (IPPN) between 2007 and 2024, on automated PD with a daytime dwell.

Background: The Therapeutic Effects of Steroids in IgA Nephropathy Global (TESTING) trial demonstrated that glucocorticoid therapy reduced proteinuria and improved kidney outcomes in patients with Immunoglobulin A Nephropathy (IgAN). Galactose-deficient IgA1 (Gd-IgA1) plays a central role in IgAN pathogenesis by promoting immune complex formation. However, the effects of glucocorticoid on pathogenic IgA levels remain unclear.

Copeptin, a stable glycopeptide derived from the precursor of arginine vasopressin (AVP), has emerged as a valuable surrogate biomarker for AVP due to its stability and ease of measurement. This narrative review explores the physiological role of copeptin, its utility as a diagnostic and prognostic biomarker in different kidney diseases, and its clinical relevance in renal tubular disorders. The clinical application of copeptin as a diagnostic biomarker is best established in the differential diagnosis of polyuria-polydipsia syndrome (PPS), distinguishing nephrogenic diabetes insipidus (NDI) from central diabetes insipidus (CDI) and primary polydipsia (PP).
