Radius bone loss with ageing assessed by high-resolution peripheral computed tomography differs in men and women

Walsh Jennifer , Paggiosi Margaret , Eastell Richard

High-resolution peripheral computed tomography (HR-pQCT) (XtremeCT, Scanco) obtains three-dimensional images of the distal radius with a resolution of 82 microns, which enables detailed study of the microarchitecture of cortical and trabecular bone. Better description of the microarchitectural changes in bone with ageing will improve understanding of which preventative and therapeutic interventions are most likely to be effective.The aim of this study wa...

Leptin is associated with bone microstructural changes in obese children

Dimitri Paul , Paggiosi Margaret , King David , Bishop Nick , Eastell Richard

Background: Bone mass is low and fracture risk is higher in obese children. We wished to ascertain the relationships of obesity-related changes in hormones with skeletal microstructure.Method: Children aged 8–15 years matched by gender and pubertal stage were recruited into lean and obese groups (18 pairs). We used high resolution peripheral quantitative computed tomography (HRpQCT – resolution-82 μm) to assess three-dimensional cortical a...

Impact of type 1 diabetes mellitus on skeletal integrity and strength assessed by HRpQCT

Devaraja Janani , Dimitri Paul , Jacques Richard , Paggiosi Margaret , Clark Carolyn , Bishop Nick

Introduction: Adults with Type 1 Diabetes Mellitus (T1DM) are at risk of premature osteoporosis and fractures. The onset of T1DM typically starts during childhood and adolescence thus the effects of diabetes on the skeleton may be established in this period. Studies in children primarily use DXA to evaluate the effects of T1DM on bone with conflicting results. We present the first study in children assessing the impact of T1DM on skeletal microstructure and strength, using HRp...

Role of cortisol in the pathogenesis of postmenopausal osteoporosis: relationship to bone structure

Debono Miguel , Bratherton Selina , Paggiosi Margaret , Gossiel Fatima , Keevil Brian , Ross Richard , Eastell Richard

Background: Excess glucocorticoids are well recognised as a cause of osteoporosis; they inhibit osteoblast function and increase osteoblast and osteocyte apoptosis resulting in thinning of the trabeculae. The circadian rhythm of bone turnover, which is linked to cortisol rhythm, is abnormal in osteoporosis. Furthermore, some studies show abnormal cortisol metabolism in osteoporosis. The aim of our study was to evaluate the day–night rhythm of cortisol and to relate cortis...
