title: Therapy insight: Osteoporosis in inflammatory bowel disease--advances and retreats.
abstract: There is a discrepancy between the high rates of reduced bone mineral density (BMD) reported in patients with inflammatory bowel disease (IBD) and the relatively low fracture rates observed in population-based studies. When fractures occur, they are most common among the elderly IBD population. It has become clear that BMD is but one of several important factors to be considered when assessing fracture risk. Ideally, BMD should be assessed selectively, as opposed to assessing this measure in all IBD patients simply because they carry an IBD diagnosis. Preventing bone loss should begin with an attempt to limit corticosteroid-induced bone loss. This can be done by using the minimum effective prednisolone dose, substituting budesonide when appropriate, administering other steroid-sparing immunomodulators, or by prescribing additional agents that enhance bone health. The administration of calcium and vitamin D appears to maintain or enhance bone mass. Bisphosphonates are of unclear additional benefit to the majority of patients who are at low fracture risk. Although more data are required to understand the best strategy to prevent fractures, a greater appreciation of the role of selective BMD testing and the utility of simple therapeutic strategies (such as calcium and vitamin D supplements) is emerging.
