Anti-rituximab antibodies: implications for clinical outcomes and safety in pediatric idiopathic nephrotic syndrome

Aug 7, 2026

The authors aimed to investigate the incidence and clinical implications of anti-rituximab antibodies (ARA) in pediatric patients with idiopathic nephrotic syndrome (INS) treated with rituximab. They found that ARA were present in 33.3% of patients, leading to higher relapse rates and increased risk of infusion-related reactions, particularly after multiple infusions. The study suggests that monitoring ARA could help identify patients at risk for treatment failure and inform personalized therapeutic approaches.

Linear growth in pediatric kidney transplant recipients

Aug 6, 2026

This study aimed to evaluate post-transplant growth in pediatric kidney transplant recipients and its association with demographic and clinical factors. The findings indicated that mean height standard deviation scores improved significantly after transplantation, particularly in the first year, with the use of recombinant human growth hormone (rhGH) linked to enhanced linear growth. Additionally, preemptive transplantation and parental height were identified as key factors associated with better growth outcomes.

Health-related quality of life in children with chronic kidney disease: clinical predictors and ROC-derived thresholds for impaired HRQoL

Aug 5, 2026

This study investigates the health-related quality of life (HRQoL) in children with chronic kidney disease (CKD) and aims to identify clinical predictors of impaired HRQoL. The authors found that children with CKD had significantly lower HRQoL compared to healthy controls, with specific renal function parameters like eGFR and BUN being associated with poorer HRQoL. They established a clinically interpretable cutoff score for HRQoL impairment and suggest that integrating HRQoL assessments into pediatric nephrology could improve patient-centered care.

Novel PAX2 variants and phenotypic heterogeneity in pediatric kidney disease: a single-center retrospective study

Jul 30, 2026

The authors aimed to characterize the clinical heterogeneity and functional consequences of novel PAX2 variants in pediatric kidney disease. Through a retrospective analysis of 15 probands, they identified 14 distinct PAX2 variants, including seven previously unreported, and observed significant variability in kidney manifestations and disease severity. Their findings underscore the importance of early genetic testing and highlight the diverse phenotypic and pathological presentations associated with PAX2-related kidney disease in children.

Anxiety and depression symptomatology in adolescents with kidney disorders during transition: "perception of illness" and the "patient paradox"

Jul 30, 2026

This study investigates the prevalence of anxiety and depressive symptoms in adolescents with chronic kidney disease (CKD) during their transition from pediatric to adult care, aiming to identify predictors of psychological distress. The findings reveal that while a significant portion of the cohort experiences clinically significant anxiety, most report minimal depressive symptoms, with medication burden and female sex being key predictors of distress. Interestingly, the adolescents with CKD exhibited lower levels of anxiety and depression compared to their healthy peers, suggesting that structured transition programs may provide protective psychological support.

Comparison of KDIGO and nRIFLE criteria for acute kidney injury in neonates with hypoxic-ischemic encephalopathy

Jul 30, 2026

This study aimed to compare the KDIGO and neonatal RIFLE (nRIFLE) criteria for diagnosing acute kidney injury (AKI) in neonates with hypoxic-ischemic encephalopathy (HIE) and to assess their clinical relevance. The findings indicated that nRIFLE criteria identified more cases of AKI and correlated with greater clinical severity, suggesting that nRIFLE may be a more effective tool for recognizing renal dysfunction in this vulnerable population.

Using health systems evidence to study and predict long-term outcomes of childhood acute kidney injury

Jul 29, 2026

The authors aim to explore the epidemiology, healthcare resource utilization, and long-term outcomes of childhood acute kidney injury (AKI) using health systems research methodologies. They highlight the challenges in studying AKI due to methodological limitations and emphasize the potential of leveraging large health administrative data to improve understanding and follow-up care for AKI survivors. The review seeks to address gaps in knowledge and improve the recognition and management of this significant pediatric health issue.

PROGRESS Study: Longitudinal analysis of antioxidant status and its relationship with heat shock proteins in children with chronic kidney disease

Jul 26, 2026

The authors aimed to investigate the longitudinal changes in antioxidant levels (superoxide dismutase, catalase, and glutathione) in children with chronic kidney disease (CKD) and their relationship with heat shock proteins (HSPs). They found that while antioxidant levels generally declined over time and showed some correlation with HSPs, only urinary catalase levels were modestly associated with better kidney function and lower risk of CKD progression. Overall, the study suggests that although altered antioxidant defenses are present in children with CKD, their predictive value for kidney outcomes is limited.

Typical or atypical hemolytic uremic syndrome? That is the question

Jul 25, 2026

The authors investigate the diagnostic challenges in distinguishing between typical hemolytic uremic syndrome (HUS) associated with Shiga toxin-producing Escherichia coli (STEC-HUS) and atypical HUS (aHUS) in a pediatric patient. They present a case of an 11-month-old boy whose unexpected drop in platelet count during recovery raised suspicion for aHUS, leading to treatment with eculizumab. The study emphasizes the importance of monitoring platelet counts against disease-specific trajectories to identify deviations from expected STEC-HUS progression and enable timely intervention.

Impact of childhood and parental smoking and substance use on nephrotic syndrome outcomes: a prospective cohort study

Jul 24, 2026

The authors aimed to investigate the impact of childhood and parental smoking, alcohol, and recreational drug use on the outcomes of nephrotic syndrome in children. Analyzing data from a prospective cohort of 732 children, they found that while a small percentage reported substance use or exposure to household smoking, there were no significant associations between these exposures and nephrotic syndrome outcomes such as relapse rates, initiation of steroid-sparing medications, or hospitalizations. The study suggests that substance exposure does not clearly affect the longitudinal outcomes of nephrotic syndrome in this population.
