The trabecular bone score (TBS) is a relatively novel textural index of bone microarchitecture.<\/jats:p><\/jats:sec><jats:sec><jats:title>Purpose<\/jats:title><jats:p>The objective of the study was to compare TBS, bone mineral density (BMD), and fracture risk in patients with endogenous CS to controls. We have investigated the association of TBS with anthropometric parameters and 25(OH) vitamin D concentrations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>The study group comprised 19 consecutive patients with CS (14 women and 5 men; mean age 45.84 \u00b1 13.15 years) and sex-, age-matched 36 controls (25 women and men; mean age 52.47 \u00b1 8.98 years). Anthropometric parameters, biochemical and hormonal data were compared between groups. Lumbar spine (L1\u2013L4) and femoral neck BMD (LS BMD, FN BMD) measurements were performed. TBS values were obtained from lumbar spine DXA images.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>TBS was significantly lower in patients with CS compared to controls (p = 0.0002). The 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture were significantly higher in the CS group than in controls (p = 0.03, p &amp;lt; 0.0001, respectively). All subjects from the CS group with fractures had low TBS value (degraded microarchitecture). TBS correlated negatively with the duration of disease in patients with CS (r = -0.590 p = 0.008).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The patients with active CS have altered bone microstructure as indicated by the decreased TBS and are at higher risk of hip and a major osteoporotic fractures. TBS seems to be a very important analytical tool facilitating fracture risk assessment in endogenous hypercortisolism.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2020.593173","type":"journal-article","created":{"date-parts":[[2021,1,21]],"date-time":"2021-01-21T09:49:55Z","timestamp":1611222595000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":25,"title":["Decreased Trabecular Bone Score in Patients With Active Endogenous Cushing\u2019s Syndrome"],"prefix":"10.3389","volume":"11","author":[{"given":"Barbara","family":"Stachowska","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jowita","family":"Halupczok-\u017by\u0142a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justyna","family":"Kuliczkowska-P\u0142aksej","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Syrycka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"Bolanowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1007\/s12020-018-1709-y","article-title":"Cushing\u2019s syndrome: comparison between Cushing\u2019s disease and adrenal Cushing\u2019s","volume":"62","author":"Hirsch","year":"2018","journal-title":"Endocrine"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1530\/EJE-11-0272","article-title":"The European Registry on Cushing\u2019s syndrome: 2-year experience.
