Analysis of Bone Quality in Adult Patients With Inflammatory Bowel Disease

"Conventional bone densitometry at the level of the proximal femur and lumbar spine (L1-L4) (anteroposterior and lateral) measured with a General Electric Prodigy Advance Full enCORE version 11.x equipment. With the data from the lateral densitometry, and using the VFA Dual Vertebral Assessment H8650DA/DM software, a quantitative morphometric analysis of the thoracolumbar vertebrae (T4-L4) will be carried out. Additionally, microarchitectural parameters of the lumbar spine will be evaluated with TBS (iNsight v3.0) and bone quality in the proximal femur with the DEXA-3D 3D-SHAPER v2.10.1 software. Vertebral fracture will be excluded from the DXA and TBS analysis of the spine."

Quantitative bone ultrasound of calcaneus evaluated with a SONOST 3000, (OsteoSys Co, Korea).

Analysis of general biochemical parameters and serum phospho-calcium metabolism, including: total calcium, albumin, phosphorus, 25-OH-vitamin D, intact PTH (iPTH), creatinine, estimated glomerular filtration rate, carboxy-terminal telopeptide of type I collagen ß-CTx (Crosslaps) and N-terminal propeptide of type I procollagen (P1NP).
