Abstract

OBJECTIVE: Glucocorticoids (GCs) alter bone strength such that patients receiving these medications have a high rate of fragility-related fractures. The purpose of this study was to assess whether concurrent treatment with GCs (prednisolone) and risedronate (an aminobisphosphonate) would prevent the reduction in bone strength induced by GCs, in a mouse model of GC-induced bone loss and in patients enrolled in a clinical study. METHODS: We evaluated mice treated with prednisolone pellets alone, GCs plus risedronate, or placebo alone and iliac crest biopsy specimens obtained from patients who were treated with GCs plus placebo or GCs plus risedronate for 1 year. We measured the mass, architecture, and physical and material properties of bone (subject to therapeutic treatments) at nanoscale to macroscopic dimensions, using synchrotron x-ray tomography, elastic modulus mapping, transmission electron microscopy, and small-angle x-ray scattering techniques. RESULTS: GC treatment reduced trabecular bone mass, microarchitecture, and the degree of bone mineralization and elastic modulus within the trabeculae. Concurrent treatment with GCs and risedronate prevented the deterioration of trabecular bone architecture, reduced the degree of mineralization, and preserved elastic modulus within the trabeculae, in both mouse and human bone. In addition, treatment with risedronate plus GCs in mice appeared to preserve bone crystal orientation, compared with treatment with GCs alone. CONCLUSION: Risedronate prevented the localized changes in mineral and material properties of bone induced by GCs, which may ultimately improve bone strength.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
