Introduction: Left ventricular hypertrophy (LVH) is the most common cardiac abnormality in chronic kidney disease (CKD). Changes in cardiac geometry and functions may occur in an early stage and worsen as CKD progresses. Recently, the role of fibroblast growth factor 23 (FGF23) is being highlighted and investigated in CKD-related cardiomyopathy. However, only a few studies have reviewed the utilization of FGF23 as a diagnostic biomarker in the pediatric CKD population. Purpose: This study aimed to identify the role of FGF23 as a biomarker in assessing cardiac changes in children with CKD. Patients and Methods: We conducted a cross-sectional study that involved children aged 2 to 18 years old with CKD stages 2 to 5D in Dr. Sardjito General Hospital, Yogyakarta, Indonesia. The level of FGF23 was measured using an immunometric enzyme-linked immunosorbent assay. LVMI, RWT, and left ventricular ejection fraction (LVEF) were assessed with echocardiography. Receiver-operating characteristic (ROC) analyses were conducted to assess the diagnostic performance of FGF23 in detecting LVH with impaired contractility. Results: A total of 43 children with CKD stages 2 to 5D were included, among whom the prevalence of LVH diagnosis was 95.35%. The area under the curve (AUC) of FGF23 to assess LVH and systolic dysfunction was 0.82 (95% CI 0.62–1.0), and the optimal cutoff point was 1413 RU/mL (sensitivity 80%, specificity 78.95%). The median concentration of FGF23 increased with the decreasing eGFR and the increasing LVMI although the systolic and diastolic functions were preserved. Conclusion: FGF23 might be used as an early biomarker to detect cardiac changes in pediatric CKD patients, particularly for LVH and impaired systolic function among children with CKD stage 2 and higher. © 2021 Palupi-Baroto et al.
