Introduction: Fibroblast growth factor-23 (FGF23) is found as a bone derived hormone which can influence the serum levels of parathormone, phosphorous and 1, 25-dihydroxyvitamin D. FGF23 may be a cardiovascular biomarker in patients with chronic kidney disease (CKD). While, FGF23 is inversely correlated with serum adiponectin level, thus it is possible that FGF23 is correlated to fat mass and related to dyslipidemia in CKD.

Objectives: In this investigation, we studied the association of serum levels of FGF23 with serum lipid profile, body mass index (BMI), and various cardiovascular risk factors in patients with CKD.

Patients and Methods: This is a cross-sectional study, which was conducted on 80 non-dialysis patients (glomerular filtration rate [GFR] <60 cc/min) with CKD. Laboratory results and demographic information recorded in pre-defined data sheets and their relationship with FGF23 were analyzed.

Results: Eighty patients were studied. Mean ± standard deviation (SD) of serum creatinine and FGF23 were 2.18 ± 0.73 mg/dl and 15.028 ± 20.20 RU/ml respectively. The correlation between FGF23, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), ApoA, ApoB, intact parathyroid hormone (iPTH), calcium, phosphorous, alkaline phosphatase, 25-hydroxyvitamin D, BMI, waist girth, serum triglyceride and cholesterol was not significant (P > 0.05). In this study, the correlations of FGF23, with serum albumin (P = 0.036) and systolic blood pressure (P = 0.001) were significant.

Conclusion: Our study showed that there are not any significant correlations among FGF23, BMI and lipid profile. There are not any significant correlations between FGF23 and age, sex, and level of calcium, phosphorous, vitamin D. However, the relationships between FGF23 and serum albumin was negatively significant. Additionally we detected a positive significant correlation of FGF23 with level of systolic blood presure.

Implication for health policy/practice/research/medical education:

In a study on 80 chronic renal failure patients not yet on dialysis with mean age of 59.82 ± 14.49 years, and serum level of fibroblast growth factor-23 (FGF23) of 15.028 ± 20.20 RU/ml, we found relationships of FGF23 with serum albumin (negative significant correlation) and systolic blood pressure (positive and significant).
