Abstract:
Objective To evaluate osteoporosis and the bone turnover markers in patients with Graves′ disease(GD) and the association of bone turnover markers including serum osteocalcin ( OCN ),I procollagen Nterminal propeptide( PINP),serum alkaline phosphatase ( ALP),and β- I collagen carboxyl-terminal peptide ( β-CTX)with thyroid hormone levels.Methods A total of 163 patients with Graves′ disease were enrolled.Serum thyroid hormone,OCN,PINP,and β-CTX levels were measured by the method of ethchemiluminescence.Serum ALP,calcium,phosphorus,and urinary calcium/creatinine ratio were measured by automatic biochemical system.Bone mineral density ( BMD ) of lumbar spines 1-4 ( L 1-4 ) and the proximal left femur was detected by dual energy xray absorptiometry.Results GD cases enrolled were composed of 43 men (26.4％ )and 120 women ( 73.6％ ),with an average age of ( 47 ± 1 ) years.There were 126 cases ( 77.3％ ) with normal BMD,and 37 cases ( 22.7％ ) with osteoporosis.OCN,ALP,PINP,β-CTX,and free T3 levels were significantly higher in the group of osteoporosis than those in the group with normal BMD( P＜0.05 or P＜0.01 ) after adjusting for sex,age,and BMI.The levels of OCN,P1NP,and β-CTX were positively correlated with serum FT3 level ( all P＜0.01 ) and were also progressively increased according to the quartile groups of FT3 levels ( P＜0.01 ) after sex,age,and BMI were adjusted.Conclusion Patients with Graves′ disease had a high incidence of osteoporosis with characristic high rate of bone turnover,which is related to the raised thyroid hormone levels.
