Fibroblast Growth Factor 23 Level and Cardiovascular Parameters in Children with Chronic Kidney Disease.

To find out the serum fibroblast growth factor 23 (FGF-23) levels in different grades of CKD, and the prevalence of abnormal left ventricular mass index (LVMI), carotid intima-medial thickness (cIMT), and central pulse wave velocity (cPWV) and the risk factors including FGF-23 for these abnormalities. Fifty-nine patients of CKD with G2 to G5, aged 2-18 y were included. The LVMI, cIMT, and cPWV were measured using standard techniques, and serum intact FGF-23 levels were estimated at enrollment. Median FGF-23 levels were significantly raised in all the grades of CKD than controls (p < 0.001), and also in G4 and G5 in comparison to G2&3 and in G5D than G5. Increased LVMI in 42 (71.2%), elevated cIMT in 30 (57.7%), and cPWV in 14 (26.9%) patients were found. The FGF-23 showed significant negative correlation with eGFRcr and positive with serum iPTH, phosphate and alkaline phosphatase levels, but had no correlations with LVMI, cIMT SDS, and cPWV SDS. Only systolic BP SDS (odds ratio 1.5, 95% CI 1.008-2.231, p = 0.046) was observed as a significant predictor for increased cIMT, while no variables had any association with abnormal LVMI and cPWV. Serum FGF-23 showed higher levels with increasing grades of CKD, but no significant association with cardiovascular parameters. Systolic BP SDS was found as a significant risk factor for increased cIMT in children with CKD. © 2021. Dr. K C Chaudhuri Foundation.
