ABSTRACT
Objective To investigate the association of vascular calcification,fetuin A and Creaction protein (CRP),and explore the influence on cardiovascular events.Methods Sixty peritoneal dialysis (PD) patients were enrolled in this study.Carotid intima-media thickness (cIMT),fetuin A and CRP,along with the other serum related parameters were detected to find out their influence on vascular calcification in PD patients.The relationship between cIMT,fetuin A,CPR and cardiovascular events was analyzed in PD patients with 18 months followed-up.Results Of the 60 PD patients,carotid intima-media thickness (cIMT) was increased in 38 patients(63.3%).Compared with the non-increased cIMT patients,serum fetuin A concentration was significantly decreased(P < 0.05),CRP(P<0.01) and calcium × phosphate products(P<0.05) were significantly increased in the highincreased cIMT group.Compared with the low-increased cIMT patients,fetuin A concentration was obviously lower(P < 0.05) and calcium×phosphate products were obviously higher(P < 0.05) in the highincreased cIMT group.Linear regression analysis discovered an obvious negative correlation between CRP and fetuin A(R2 =0.629,F=47.522,P < 0.01),as well as fetuin A and calcium×phosphate products (R2=0.299,F=11.948,P=0.002).Multiple regression analysis indicated that fetuin A was independently negatively correlated with cIMT(B=-0.019,t =-6.042,P < 0.01).At 18 months,there were 36 newly-happened cardiovascular events and among which 6 cases died.Logistic regression analysis found that increased cIMT was risk factor to cardiovascular events in PD patients(OR=3.691,95%CI 1.467-9.258,P=0.006).Conclusion Decreased fetuin A and increased calcium×phosphate products deteriorate carotid calcification in PD patients.Micro-inflammation of PD patients represented by high CRP levels may increase calcium×phosphate products by depressing the fetuin A level,and in the end will stimulate carotid calcification.Increased cIMT is a risk factor for cardiovascular events.
