Abstract:
Objective:To investigate the correlation between serum recombinant sclerostin (SOST) and dickkopf-related protein 1 (DKK-1) levels and bone metabolism indexes in patients with osteoporosis after differentiated thyroid cancer surgery.Methods:A total of 110 patients diagnosed with osteoporosis after differentiated thyroid cancer surgery were recruited as the study group, and another 110 patients without osteoporosis diagnosed after differentiated thyroid cancer surgery were recruited as the control group. The general data, bone mineral density, serum SOST, DKK-1 levels and bone metabolism indicators N-terminal propeptide of type I procollagen (PINP), bone alkaline phosphatase (BALP), beta-isomerized C-telopeptide (β-CTX), 25-hydroxyvitamin D3 [25- (OH) D3] levels were compared between the two groups. The correlation between serum SOST, DKK-1 levels and bone metabolism indexes was analyzed, and the risk factors affecting the formation of osteoporosis were explored.Results:The T value of bone mineral density in the study group (-3.27±0.92) was significantly lower than that in the control group (-1.23±0.27, t=22.32, P<0.001). The serum SOST (15.84±1.34, t=32.53, P<0.001) and DKK-1 (5.96±1.40, t=4.82, P<0.001) levels in the study group were significantly higher than those in the control group (SOST: 10.24±1.21, DKK-1: 5.05±1.40). The serum PINP (40.95±9.84, t=7.59, P<0.001), BALP (23.14±5.26, t=5.06, P<0.001) and β-CTX (1.07±0.54, t=4.96, P<0.001) in the study group were significantly higher than those in the control group (31.48±8.64, 19.64±4.99, 0.78±0.29), and the 25- (OH) D3 level (13.68±4.49) was significantly lower than that of the control group (18.31±5.72, t=6.68, P<0.001). Serum SOST was positively correlated with PINP ( r=0.33, P=0.001), BALP ( r=0.23, P=0.016) and β-CTX ( r=0.19, P=0.046), but not with 25- (OH) D3 ( r=-0.09, P=0.349). Serum DKK-1 was positively correlated with PINP ( r=0.19, P=0.044), BALP ( r=0.26, P=0.007) and β-CTX ( r=0.21, P=0.028), but not with 25- (OH) D3 ( r=-0.16, P=0.088). Serum SOST and DKK-1 levels were independent risk factors for osteoporosis (all P<0.05) . Conclusion:Serum SOST and DKK-1 levels are independent risk factors for the formation of osteoporosis, which are significantly positively correlated with bone metabolism indexes PINP, BALP, and β-CTX in patients with osteoporosis after differentiated thyroid cancer surgery.
