Abstract:

Objective To investigate the relation between osteopontin (OPN),fibroblast growth factor 23 (FGF23) and vascular calcification in maintenance hemodialysis (MHD) patients. Methods Totally,147 patients with MHD at Hai'an People's Hospital from January 2018 to June 2022 were enrolled. The general data and laboratory routine test results of all the patients were collected,and serum OPN and FGF23 levels were determined. The patients' vascular calcification was scored by X-ray images of abdomen,pelvis and hands,and the total score was 10 points. According to the total score of vascular calcification,the patients were classfied into non-vascular calcification group (total score 0)(49 cases),vascular calcification total score 1 to 5 group (74 cases) and vascular calcification total score 6 to 10 group (24 cases). Results The dialysis time,the levels of total calcium,phosphorus,intact parathyroid hormone(iPTH),OPN and FGF23 were increased successively in non-vascular calcification group,vascular calcification total score 1 to 5 group and vascular calcification total score 6 to 10 group (P<0.05),and the hemoglobin (Hb) level and Kt/V ratio were decreased successively (P<0.05). Long dialysis time [odds ratio(OR)=1.070],high total calcium (OR=2.540),high phosphorus(OR=4.170),high OPN (OR=1.010) and high FGF23 (OR=1.060) were risk factors for vascular calcification in MHD patients. High Kt/V ratio (OR=0.020) was a protective factor for vascular calcification. The consistency (true positive rate+true negative rate) of phosphorus was the highest,but there was no statistical significance between those of phosphorus and OPN (P=0.89),and it was higher than that of FGF23 (P=0.02). Conclusions The abnormal increase of OPN and FGF23 in MHD patients is related to vascular calcification,and they are potential intervention targets.
