Expression of sclerostin and bone morphogenetic protein-7 (BMP-7) in serum of patients with chronic kidney disease-mineral and bone disorder (CKD-MBD) and their correlation with calcium and phosphorus metabolism
Abstract Calcium and phosphorus metabolism involves in patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). Sclerostin and bone morphogenetic protein-7 (BMP-7) are closely related to bone formation. This study aims to assess sclerostin and BMP-7’s role in renal function, blood c...

| Sumario: | Abstract Calcium and phosphorus metabolism involves in patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). Sclerostin and bone morphogenetic protein-7 (BMP-7) are closely related to bone formation. This study aims to assess sclerostin and BMP-7’s role in renal function, blood calcium and phosphorus in CKD-MBD. 86 CKD-MBD patients were collected as the case group and 86 healthy subjects were selected as control group. ELISA was used to detect Sclerostin and BMP-7 serum level. The automatic biochemical analyzer was used to detect liver and kidney function. Blood calcium and phosphorus level, and iPHT level was detected by immunoradiation. No differences were found regarding age, gender, and BMI between case group and control group (P > 0.05). Compared to controls, CKD-MBD patients had significantly reduced blood calcium and eGFR level, and increased Scr, BUN, blood phosphorus and iPTH level (P < 0.05) with increased Sclerostin (t = 33.86, P < 0.001), and reduced BMP-7 level (t = 329.38, P < 0.001). Scr, BUN, blood phosphorus levels and iPTH were correlated with Sclerostin positively (P < 0.05) and BMP-7 negatively (P < 0.05). eGFR and blood calcium were correlated with Sclerostin negatively (P < 0.05) and BMP-7 positively (P < 0.05). Scr, eGFR, blood calcium levels, blood phosphorus levels, and iPTH are independent risk factors for serum Sclerostin and BMP-7 level. Sclerostin and BMP-7 changes may be important factors affecting the occurrence of CKD-MBD. Renal function, blood calcium and blood phosphorus are independent risk factors for serum Sclerostin and BMP-7 level. |
