RESUMEN

Increased carotid intima media thickness (cIMT) is one of the early changes seen in chronic kidney disease (CKD) associated cardiovascular disease. This study aimed to determine cIMT measurements and its association with cardiovascular risk factors, including fibroblast growth factor-23 (FGF-23) and fetuin-A, in South African children with CKD. 72 children (5 - 18 years) with CKD; 20 with CKD I, 23 with CKD II - IV, 29 with CKD V (on dialysis) were recruited. Each patient had a clinical examination and blood samples assessed for creatinine, urea, albumin, calcium, phosphorus, parathyroid hormone, alkaline phosphatase, total cholesterol, hemoglobin, C-reactive protein, vitamin D, fetuin-A, and FGF-23. cIMT was measured with high-resolution ultrasound. The mean age was 10.8 (3.5) years, and there were 49 males and 23 females (2 : 1). The overall median (range) cIMT was 0.505 mm (0.380 - 0.675) and was highest in patients with dialysis-dependent CKD (p = 0.003). Mean arterial pressure (MAP), hemoglobin, and PTH showed a significant correlation with cIMT (p < 0.001, p = 0.034, and p = 0.002, respectively). After adjusting for confounders in a multivariable analysis, disease duration, MAP, hemoglobin, and estimated glomerular filtration rate (eGFR) were independently associated with cIMT, p = 0.039, 0.001, 0.006, and 0.001, respectively. No significant relationship between cIMT and plasma levels of fetuin-A and FGF-23 was found. This study reports high cIMT measurements and their independent association with disease duration, MAP, hemoglobin, and eGFR. However, no similar association was found with fetuin-A and FGF-23.
