Special Issue Information

Dear Colleagues,

This Special Issue, entitled “Kidney Disease in Children: From Bedside to Bench and Back”, aims to contain valuable articles regarding all aspects of pediatric nephrology, from fundamental research to clinical application. The readers will have the opportunity to become acquainted with the spectrum of all major aspects of pediatric nephrology, from neonatal to adolescent perspectives, from rare genetic disorders to well-known diseases, and from transient acute kidney injury to irreversible end-stage kidney disease. The content should help to show both scientists and clinicians that there is only one way to form a practical strategy: we must start with in-depth analysis of the changeable clinical picture, then bridge clinical to molecular data before coming back to the patient with molecular solutions to clinical challenges. No matter how far we reach, the patient must remain in focus, and will always give us the final answer. Therefore, let these articles give us courage to come back to the bedside and to use the bench in everyday practice for the good of all patients.

Background: Hypertension is prevalent in the pediatric population, with estimated rates between 2% and 5%, and its incidence is rising globally. This study offers a single-center analysis of hypertension in children. Methods: a retrospective chart review was conducted involving children aged 1 month to 13 years diagnosed with hypertension. Results: The study included a total of 129 children. Secondary hypertension was identified in 103 patients (79.8%), while primary hypertension was noted in 26 patients (20.2%). Primary hypertension was more common among pre-teen children (50.0%), whereas secondary hypertension predominantly affected those aged 1 to 5 years. Renal parenchymal disease emerged as the most frequent etiology of secondary hypertension, followed by endocrine disorders and vascular issues. No significant correlation was found between hypertension and obesity. The primary complications associated with hypertension in these children were cardiovascular, followed by neurological issues. A small proportion (14.7%) managed their hypertension solely through lifestyle modifications, while the majority required additional antihypertensive medications. At the final follow-up, 50% of the children demonstrated improved blood pressure readings. Conclusion: The findings indicate a higher prevalence of secondary hypertension compared to primary hypertension among the studied population. This study underscores the necessity for heightened awareness among pediatricians regarding the early identification and management of hypertension. Larger population-based studies are warranted to further investigate the prevalence, causes, and outcomes of hypertension in this region. Full article

Background: Pediatric CKD is associated with a high risk of cardiovascular disease (CVD). Early detection of subclinical CVD in childhood CKD can be achieved through various cardiovascular (CV) assessments, including carotid intima–media thickness (cIMT), ambulatory blood pressure monitoring (ABPM), and arterial stiffness indices. Lactoferrin (LF), a key functional glycoprotein found in breast milk, has been linked to several diseases and has potential as a biomarker. Methods: In our study of 102 children with CKD stages G1–G4, we explored the relationship between LF and CV risk markers. Results: We found that LF concentration was not related to the severity or underlying causes of childhood CKD, but was positively correlated with overweight/obesity. Lower LF levels were correlated with increased cIMT and elevated arterial stiffness indices. Notably, abnormalities in ABPM profiles were observed in up to 60% of the children with CKD, with low LF levels linked to nighttime hypertension, nocturnal non-dipping, and ABPM abnormalities. Conclusions: In conclusion, LF shows promise as a biomarker for detecting subclinical CVD in children with CKD. Its potential utility in early detection could be instrumental in guiding timely interventions and improving long-term CV outcomes, although further research is needed to clarify the underlying mechanisms.

Background/Objectives: Congenital anomalies of the kidney and urinary tract (CAKUT) are the main cause of chronic kidney disease (CKD) requiring renal replacement therapy (RRT) in children, being the leading cause (50–70%) of end-stage renal disease (ESRD) in children and young adults. Our study aimed to assess the natural evolution of various antenatally diagnosed renal malformations and to identify potential prognostic factors to guide the therapeutic management of patients with CAKUT. Methods: We conducted a retrospective study on 205 children with CAKUT. For each patient, analyzing their medical records, we established the nadir value of serum creatinine, defined as the lowest creatinine level during the first year of life. We assessed the value of nadir creatinine as a prognostic marker in patients with CAKUT, and using an ROC curve, we also determined a threshold value of nadir creatinine that predicted progression to ESRD. Results: The male-to-female ratio was 2.8 to 1. The mean gestational age at detection was 29.85 weeks (±6.71). A total of 36 patients (17.6%) had impaired renal function, of which 8 (3.9% of the total) progressed to ESRD. The mean nadir creatinine in patients with ESRD was 1.39 mg/dL. A nadir creatinine cut-off of 0.98 mg/dL had high sensitivity and specificity in identifying patients with progression to ESRD, with an AUC of 0.95 and a 95% confidence interval between 0.86 and 1.05 mg/dL. Conclusions: Our results support the value of nadir creatinine in predicting progression to ESRD, consistent with previously published data. Full article

Acute kidney injury (AKI) presents significant challenges in pediatric care, often remaining underrecognized. This paper provides an overview of pediatric AKI, highlighting its epidemiology, pathophysiology, diagnosis, predisposing conditions, and treatment. AKI in children stems from diverse causes, including renal tubular damage, vasoconstriction, and inflammation. Diagnosis relies on traditional markers such as serum creatinine and urine output, alongside emerging biomarkers such as Cystatin C, NGAL, KIM-1, IL-18, TIMP-2 and IGFBP7, urinary calprotectin, URBP4, L-FABP, and clusterin. Various pediatric conditions predispose to AKI, including type 1 diabetes, pneumonia, bronchiolitis, appendicitis, gastroenteritis, COVID-19, multisystem inflammatory syndrome, sickle cell disease, and malignancies. Treatment entails supportive care with fluid management and, in severe cases, renal replacement therapy. Timely recognition and management are essential to mitigating adverse outcomes. Enhanced awareness and integration of novel biomarkers could improve pediatric AKI care, warranting further research for better diagnosis and management. Full article
