Assessment of bone quality with trabecular bone score in patients with inflammatory bowel disease

Abstract Inflammatory bowel disease (IBD) patients have a significant risk of developing bone loss. The trabecular bone score (TBS) is a relatively new parameter used to provide information on bone quality. The study cohort included 81 patients with IBD and 81 healthy controls. Blood tests, dual-energy x-ray absorptiometry (DXA), including TBS, were assessed. Harvey–Bradshaw Index (HBI) for Crohn's disease (CD) and the Partial Mayo Score for ulcerative colitis (UC) were used for evaluation of clinical disease activity. Compared with the healthy controls, the IBD patients had lower lumbar spine (LS) bone mineral density (BMD) (1.06 ± 0.18 vs. 1.16 ± 0.15 g/cm2, p < 0.005), hip BMD (0.88 ± 0.13 vs. 0.97 ± 0.13 g/cm2, p < 0.005) and TBS (1.38 ± 0.1 vs. 1.43 ± 0.1, p < 0.005) values. The patients with stricturing CD had lower TBS (1.32 ± 0.13 vs. 1.40 ± 0.9, p = 0.03) and LS BMD (0.92 ± 0.19 vs. 1.07 ± 0.1, p = 0.01) values compared with those with non-stricturing CD. Multivariate regression model analysis identified HBI as independent factor associated with TBS. Our results support that all DXA parameters are lower in patients with IBD than in healthy patients. Moreover, TBS is a valuable tool for assessment of bone impairment in active CD.
