Bone mineral density (BMD) changes were estimated in kidney recipients. In 63 patients aged 24–64 years, measured creatinine clearance at the end of the first posttransplant year was >50 ml/min and remained stable over the study period, bone mineral density (BMD) was estimated in the lumbar spine, femoral neck, Ward’s triangle and the distal third of the radius using dual energy absorptiometry (DEXA) 0.1–4, 12–18 and 23–36 months after transplantat...

Objective: To investigate the characteristics and related factors of bone mineral density (BMD) in men of different ages with type 2 diabetes.Methods: Four hundred and forty four male patients diagnosed with type 2 diabetes and 208 healthy men were involved from 2013 to 2014. The BMD of all men including lumbar spine (L1–L4), femoral neck, trochanter, and total hip were detected using dual-energy X-ray absorptiometry produced by the US company. We g...

In advanced ER+ve breast cancer, the propensity of bone involvement is 85%. Similarly in advanced lung cancer, 30–40% of patients develop bone metastases, and as recent advances in lung cancer therapies improve survival, the number of patients living with bone metastases is expected to increase. At the same time there is a paucity of especially ER+ and osteoblastic animal models available. We present herein the development of four mouse models of breast and lung cancer su...

Mutations in the C-propeptide cleavage site of both COL1A1 and COL1A2 cause dominant high bone mass (HBM) osteogenesis imperfecta (OI), characterized by bone hypermineralization. To elucidate the role of C-propeptide processing in bone formation, we generated heterozygous HBM mice in which both residues of the COL1A1 cleavage site were mutated to prevent cleavage by BMP1. HBM mice are smaller than WT in both weight and length and have extremely brittle bones....

Background: Despite the large amount of studies published on the association of vitamin D deficiency with higher incidence of falls and fractures, the threshold for a sufficient serum 25(OH)D concentration remains subject to a considerable debate. There has also been no clear consensus on the assessment and treatment of vitamin D deficiency.Objective: To examine the prevalence of vitamin D deficiency and/or insufficiency and its impact on calcium/phospha...

A randomized, placebo-controlled phase 2 study evaluated the safety and efficacy of BA058, an analog of hPTHrP(1–34), in postmenopausal women with severe osteoporosis. 221 patients were randomized to received BA058 20, 40, and 80 μg, placebo or teriparatide (TP) 20 μg, by daily s.c. injection. 184 (83%) patients completed an initial 24 weeks of treatment. The mean percent change in lumbar spine BMD at 24 weeks was 1.6% with placebo, 6.7% with BA058 80 μg, a...

Introduction: Aromatase inhibitors (AI) used as adjuvant treatment of hormone-sensitive breast cancer reduce the level of circulating estrogen and cause accelerated bone loss. The aim of this study is to investigate the prevalence of osteoporosis in women with breast cancer and the effect of chemotherapy on the risk of osteoporosis.Methods: Three hundred and sixty women with hormone-sensitive breast cancer who were scheduled to start treatment with AI we...

Poor bone mineralization remains a major health problem in patients with Thal and has been linked to functional zinc deficiency despite adequate dietary intake. The global etiology of poor bone mineralization includes inadequate dietary intake of calcium and vitamin D, endocrinopathies leading to disturbed calcium homeostasis, dysregulation of the GH–IGF1 axis, and delayed puberty, all resulting in limited growth, decreased bone formation and increased bone resorption. Th...
