A 2008 panorama on osteoporosis and inflammatory bowel disease.

Abstract

The availability of osteodensitometry has contributed significantly to increase the awareness of inflammatory bowel disease (IBD)-associated bone disease. Reported osteoporosis prevalence in patients with IBD range from 2% to 30%. The fractures risk varies between studies, influenced by demographic, clinical and genetic factors. The main pathogenetic factors involved are malabsorption, treatment with glucocorticoids, inflammation (increased cytokine production) and hypogonadism. A screening should be considered for all patients with small bowel Crohn's disease and especially for those with extensive disease, multiple resections, and malnutrition. Supplementation with both calcium and vitamin D is frequently the first step taken, but is insufficient to inhibit bone loss in many patients requiring use of glucocorticoids. Among available therapies, only biphosphonates are effective for treatment of glucocorticoid-induced osteoporosis.
