LBODP055 Discrimination Effectiveness Of Radiofrequency Echographic Multispectrometry As Non Invasive Method For Osteoporosis Diagnosis Applied To Elderly Women With Type 2 Diabetes

Type 2 diabetes mellitus (T2DM) is associated with an increased risk of fracture, although bone mineral density (BMD) is unaltered or higher in diabetic patients, measured by Dual-energy X-ray absorptiometry (DXA). This paradox could be explained from compromise bone microarchitecture that induce abnormal bone cell function and matrix structure, with increased osteoblast apoptosis, diminished osteoblast differentiation, and enhanced osteoclast-mediated bone resorption.1 In this context, a non-invasive method for assessing the bone density and quality on the axial reference sites (lumbar spine and proximal femur) called Radiofrequency Echographic Multi Spectrometry (REMS), has been introduced and clinically validated. This study aimed to evaluate whether the use of the REMS technique may improve the identification of osteoporosis in T2DM patients. A cohort of ABOUT 100 elderly women with T2DM and mean age 70.5 (± 7.6) years, and 100 healthy age-matched controls underwent DXA and REMS scans on the same anatomical sites (lumbar spine and proximal femur). DXA measurements were all higher in T2DM than controls; instead, all REMS​​ measurements were lower in T2DM than controls. Moreover, the percentage of T2DM women classified as "osteoporotic", on the basis of BMDREMS was markedly higher with respect to those classified by BMDDXA (47. 0% vs 28. 0%, respectively). On the contrary, the percentage of T2DM women classified as osteopenic or normal by BMDDXA was higher with respect by BMDREMS (48.8% and 23.2% vs 38.6% and 14.5%, respectively). T2DM women with fragility fractures presented lower values of both BMDDXA and BMDREMS at the lumbar spine with respect to those without fractures; however, the difference was significant only for BMDREMS (p<0. 05). In conclusion, BMDDXA, as expected, were higher in women with T2DM, while BMDREMS were lower in women with T2DM with respect to controls. Therefore, the data suggest that REMS could be a good diagnostic tool in demonstrating the diabetes-associated bone disease, due to its ability to assess bone quality2 and that may represent a useful approach to enhance the diagnosis of osteoporosis in patients with T2DM.1.
