LBSAT141 Bone Health In Patients With Adrenal Disorders
Journal of the Endocrine Society(2022)
摘要
Abstract Introduction Limited data suggest low bone density in patients with adrenal adenomas. However, most studies are retrospective, single-center, and none were conducted in the United States. We aimed to determine the impact of cortisol and aldosterone excess on bone density. Methods We conducted a preliminary analysis of data from our multicenter, prospective observational study of adult patients with adrenocortical hormone excess and referent subjects without adrenal disorders (January 2019 - March 2022). Patients were diagnosed with non-functioning adenomas (NFA), adenomas with mild autonomous cortisol secretion, MACS (defined as cortisol following an overnight 1-mg dexamethasone suppression test (DST)>1.8 mcg/dL), adrenal or pituitary Cushing syndrome (CS), primary aldosteronism (PA), and concomitant PA-MACS. Referent subjects were patients undergoing cross-sectional imaging for reasons other than adrenal disease. All participants were interviewed about their bone health, and had bone density measurements at the spine, hips, and/or radius. Bone disease was defined as osteopenia (T-score -1.1 to -2.4), or osteoporosis (T-score < -2.5). Results A total of 417 participants included 156 referent subjects (88, 56% women, median age 65, range 2-95 years) and 261 patients (190, 73% women, median age 59, range 21-88 years). Patients were diagnosed with NFA (51, 19%), PA (46, 17%), MACS (122, 47%), PA-MACS (12, 5%), and CS (30,12%). When compared to referent subjects, sex- and age-adjusted analysis demonstrated an increased prevalence of bone disease only in patients with CS (OR 4.8, 95%CI 1.7-13), but not in other adrenal disorders. After excluding patients with CS, those with post-DST cortisol >5 mcg/dL demonstrated a higher prevalence of bone disease when compared to patients with post-DST cortisol between 1.8-5 mcg/dL (OR 2.8, 95%CI 1.2-6.5) and those with post-DST cortisol <1.8 mcg/dL (OR 2.7, 95% CI 1.1-6.7). Patients with MACS and post-DST cortisol between 1.8-5 mcg/dL did not demonstrate increased sex and age-adjusted prevalence of bone disease compared to those with post-DST <1.8 mcg/dL or referent subjects. However, using post-DST cortisol as a continuous variable, we found that after adjusting for sex and age, the risk of bone disease in patients increased by 13% (OR 1.13, 95%CI 1.6-1.2) for every 1 mcg/dL increase in post-DST cortisol. Conclusions The prevalence of osteopenia and osteoporosis increases proportional to the increase in post-DST cortisol concentrations. Patients with CS, and those with MACS and post-DST cortisol > 5mcg/dL have the highest prevalence of bone disease. Presentation: Saturday, June 11, 2022 1:00 p.m. - 3:00 p.m.
