Inflammatory bowel disease and the risk of fracture after controlling for FRAX.
Artikel i vetenskaplig tidskrift, 2013

BACKGROUND: Subjects with inflammatory bowel disease (IBD) are at increased risk for hip and other major osteoporotic fractures. However, previous analyses have not fully accounted for differences in bone mineral density (BMD) and other clinical factors that affect the risk of fracture. The World Health Organization Fracture Risk Assessment tool (FRAX®) can be used to predict the 10-year fracture riskfrom BMD and clinical risk factors. METHODS: A population based database containing clinical information on all IBD subjects in the province of Manitoba, Canada, was linked with the Manitoba Bone Mineral Density Database, which contains results of all dual X-ray absorptiometry (DXA) scans in the province. FRAX probabilities were calculated for all subjects aged50 years or more undergoing baseline DXA testing. Subjects were followed for occurrence of major osteoporotic fractures (MOF; hip, clinical spine, wrist, humerus). Cox proportional hazards models were used to determine whether IBD was independently predictive of MOF or hip fracture. RESULTS: After controlling for FRAX fracture probability computed with BMD, IBD was not associated with a significantly increased risk for MOF (HR 1.12, 95%CI 0.83-1.55) but was associated with an increased risk for hip fracture (HR 2.14, 95%CI 1.26-3.65).The addition of femoral neck T-score to FRAX probability without knowledge of BMD had a negligible effect on the estimated hazard ratios for IBD, suggesting that IBD mediates any effect on fracture risk independently of femoral neck BMD CONCLUSION: After controlling for FRAX probability, subjects with IBD are not at an increased risk for overall MOF, but may be at increased risk of hip fracture. © 2012 American Society for Bone and Mineral Research.
