Angiotensin-converting enzyme inhibitors (ACEi) for renin-angiotensin-aldosterone system (RAAS) blockade are routinely used to slow CKD progression. However, Vitamin D may also promote renoprotection by suppressing renin transcription through cross-talk between RAAS and Vitamin D -fibroblast growth factor-23 (FGF-23)-Klotho pathways. To determine whether Vitamin D levels influence proteinuria and CKD progression in children, we performed a post hoc analysis of the Effect of Strict Blood Pressure Control and ACE Inhibition on Progression of CKD in Pediatric Patients (ESCAPE) cohort. In 167 children (median EGFR 51 ml/min per 1.73 m2), serum 25-hydroxyvitaminD(25(OH)D),FGF-23, andKlotho levelsweremeasuredatbaselineandafteramedian8months onACEi.Childrenwith lower 25(OH)D levels had higher urinary protein/creatinine ratios at baseline (P=0.03) and at follow-up (P=0.006). Levels of 25(OH)D and serum Vitamin D -binding protein were not associated, but 25(OH)D #50 nmol/L associated with higher diastolicBP(P=0.004).ACEi therapy alsoassociatedwith increasedKlotho levels (P
