Fetuin-A levels, its correlation with vascular calcification and other biochemical markers of chronic kidney disease-mineral and bone disorder (CKD-MBD) has not been studied in Indian end-stage renal disease population. Forty patients on dialysis for more than 3 months were studied. Biochemical parameters of CKD-MBD, highly sensitive-C reactive protein (hs-CRP), lipid profile and fetuin-A levels were estimated. Multi-slice computed tomography (MSCT) at the level of L1–L4 was done, and calcification score calculated using AJ 130 smart score. Levels of fetuin-A were correlated with calcification score and biochemical markers of CKD–MBD. Mean fetuin-A levels were 0.33 ± 0.098 g/l. Positive correlation of abdominal aortic calcification scores was found with age (P < 0.01) and duration of dialysis (P = 0.018). No correlation was detected between MSCT score, calcium phosphate product, intact parathyroid hormone, vitamin D, triglycerides and fetuin-A, and there was no correlation between fetuin-A levels, age, dialysis duration and calcium phosphate product but a significant correlations with vitamin D3 (P = 0.034), serum albumin (P = 0.002) was detected. Inverse correlation with hs-CRP was obtained. Patients with ischemic heart disease had numerically lower levels of fetuin-A (P = 0.427) and numerically higher MSCT score (P = 0.135). Patients with low hs-CRP (<10) had numerically higher fetuin-A levels (P = 0.090) and significantly low MSCT scores (P = 0.020). Calcium deposition seen on MSCT increases with age and duration of dialysis but is not related to fetuin-A levels. Inconclusive relationship exists with other parameters of CKD-MBD. Large controlled studies are needed to establish the role of fetuin-A in vascular calcification in Indian population.
