Abstract EN
Disorders of bone and mineral metabolism contribute to an increased prevalence of vascular calcification (VC) with its adverse clinical outcomes in patients with chronic kidney disease (CKD).
The pathogenesis of VC is not fully understood.
Fetuin-A is one of the inhibitors of calcification whose level is lowered in patients with CKD.
In addition fetuin-A 256Ser / Ser (allele G) might affect serum fetuin-A levels.
The aim of this work was to study the association between fetuin-A and its gene and VC and also with bone mineral density (BMD) in patients with CKD on conservative treatment, on maintenance of hemodialysis (HD) and those who underwent renal transplantation.
This study included twenty eight CKD patients on HD, seventeen CKD patients on conservative treatment and twelve patients who underwent transplantation in addition to sixteen healthy controls.
All were subjected to history taking, clinical examination, laboratory investigations including fasting serum glucose, urea, creatinine, albumin, lipid profile, C-reactive protein (CRP), estimated glomerular filteration rate (e-GFR), calcium, phosphorus, calcium by phosphorus product (Ca•PO4), intact parathyroid hormone (iPTH), alkaline phosphatase (Alk), fetuin-A and genotyping for the common functional polymorphisms on fetuin-A (Thr256Ser) using the Polymerase chain reaction (PCR) technique.
Radiological examination included ultrasonography of carotid arteries and assessment of VC by plain X-ray and assessment of BMD.
Serum calcium was lower, phosphorus, Ca•PO4, iPTH and Alk were higher in all patient groups than control.
Fetuin-A was lower in all patient groups compared to controls.
VC was detected in 39.2 % HD patients, 29.4 % patients on conservative treatment and 25 % patients on transplantation.
T-score of BMD was significantly lower in all patient groups than control.
There was no statistically significant difference between patients and control groups according to the frequencies of the three fetuin-A genotypes (C fi G) but the distribution of the fetuin-A (C fi G) ; Thr256Ser gene polymorphisms in the studied subjects showed significant correlation with low serum fetuin-A levels.
VC was associated with older age, male gender, longer HD duration, lower albumin, higher LDL-c, higher carotid plaques and lower T-score value of BMD.
VC was evident in patients with CKD and it is related to atherosclerosis and lower BMD.
Fetuin- A was lower in all patients with CKD with significant relation between serum fetuin-A level and its gene polymorphism but not with VC.
