ABSTRACT
Background Chronic kidney disease (CKD) is associated with accelerated cardiovascular (CV) risk, particularly due to subclinical atherosclerosis. Carotid intima-media thickness (CIMT) is a non-invasive marker of early athero-sclerotic changes. Altered mineral metabolism in CKD, also known as CKD-mineral bone disorder (CKD-MBD), may contribute to vascular damage. We evaluated the association between CIMT and mineral metabolism markers in people with diabetes who had pre-dialysis CKD. Methods A cross-sectional observational study was done in 110 adults with diabetes and pre-dialysis CKD. Biochemical markers including serum phosphate, intact parathyroid hormone (iPTH), fibroblast growth factor (FGF)-23, and 24-hour urinary phosphate were analyzed. CIMT was measured using B-mode ultrasonography. Correlation and regression analyses were performed. Results CIMT showed significant positive correlations with serum phosphate, FGF-23, iPTH, and serum creatinine, and negative correlations with nephron index and urinary phosphate excretion. Serum phosphate >6 mg/dl strongly predicted CIMT >0.9 mm. Conclusion Mineral metabolism markers, particularly serum phosphate and FGF-23, are significantly associated with subclinical atherosclerosis in CKD. Monitoring these parameters may aid in assessment of early CV risk in patients with CKD.
