Abstract
Background
Fibroblast growth factor 23 (FGF23) levels increase as kidney function decreases and are associated with increased mortality in patients with chronic kidney disease (CKD). Inflammation has also been shown to increase FGF23 production in adults; however, this has not been validated in pediatric patients with CKD. Furthermore, previous studies on children involved a single measurement of FGF23 without a follow-up, and a few studies have examined changes in FGF23 levels.
Methods
We measured the levels of serum intact FGF23, tumor necrosis factor-α (TNF-α), and interleukin-6 as parameters of inflammation and other variables related to bone metabolism at baseline and after 1 year in 62 pediatric patients with CKD (stages 2–5D, 1–16 years old). Factors related to changes in FGF23 levels were investigated.
Results
The median age of patients at the evaluation was 10.5 years (interquartile range 6.0–14.0), and the estimated glomerular filtration rate (eGFR) was 59.0 mL/min/1.73 m2 (45.1–69.3). Primary diseases included congenital anomalies of the kidney and urinary tract, ischemic kidney, and glomerulonephritis. The baseline value of FGF23 was 66.5 pg/mL (48.3–96.4), and percent change in FGF23 levels after 1 year was 8.5% (− 29.9–74.7). The percent change in FGF23 levels showed a negative correlation with that in eGFR (P = 0.010), and a positive correlation with that in TNF-α levels (P = 0.035). A multivariate linear regression analysis identified TNF-α as an independent factor increasing FGF23 levels.
Conclusions
An increase in TNF-α levels is associated with elevation of FGF23 levels in pediatric patients with CKD.
