Clinical and endocrine correlates of circulating sclerostin levels in patients with type 1 diabetes mellitus.
Type 1 diabetes mellitus (T1DM) increases fragility fractures due to low bone mass, micro-architectural alterations and decreased bone formation. Sclerostin is expressed by osteocytes and inhibits osteoblastic bone formation. We evaluated serum sclerostin levels in T1DM and their association with bone mineral density (BMD), bone turnover, glycaemic control and physical activity. ⋯ Sclerostin serum levels were increased in patients with T1DM, and the positive correlation of age with serum sclerostin levels was stronger in T1DM. There was no effect of serum sclerostin levels on markers of bone metabolism and they do not explain the detrimental effects of T1DM on BMD.
