Abstract:
Objective:To explore the association of bone resorption marker β carboxyterminal peptide of collagen Ⅰ (β-CTX) with hypercalcemia in patients with Graves′ disease (GD).Methods:287 patients with GD who were hospitalized in the endocrinology department of Fuyang People′s Hospital from January 2021 to December 2021 were divided into control group ( n=251) and hypercalcemia group ( n=36) according to the corrected blood calcium level. The clinical data and serum β-CTX level of the two groups were compared. Logistic regression model was used to analyze the risk factors of hypercalcemia in GD patients. Pearson correlation was used to analyze the correlation between serum β-CTX level and other indexes. Results:Of the 287 GD patients, 36 were diagnosed as hypercalcemia, and the incidence of hypercalcemia was 12.54%. The levels of free triiodothyronine (FT3), free thyroxine (FT4), blood phosphorus (P) and β-CTX in hypercalcemia group were higher than those in control group, and the total parathyroid hormone (iPTH) in hypercalcemia group were lower than those in control group (all P<0.05). Multivariate Logistic regression analysis showed that FT3 ( OR=1.283, 95% CI: 1.049-1.570, P<0.05), iPTH ( OR=0.924, 95% CI: 0.863-0.989, P<0.05), β-CTX ( OR=2.488, 95% CI: 1.193-5.189, P<0.05) were the influencing factors for hypercalcemia in GD patients. Pearson correlation analysis showed that β-CTX was positively correlated with FT3, FT4, blood calcium, P, alkaline phosphatase (ALP), total procollagen type I amino end terminal peptide (PINP), N-bone-gamma-carboxyglutamic-acid-containing proteins (N-MID) and 25(OH)D, and negatively correlated with iPTH (all P<0.05). Conclusions:β-CTX is highly expressed in the serum of GD patients with hypercalcemia, which is a risk factor for the occurrence of hypercalcemia in GD patients.
