PROJECT SUMMARY/ABSTRACT Mild autonomous cortisol secretion (MACS) is diagnosed in up to 50% of patients with adrenal adenomas1, affecting 1-2% of adult population. MACS is diagnosed based on abnormal cortisol following dexamethasone suppression; however, 24h urine cortisol concentrations are usually normal. As we recently showed in the work sponsored by the current NIDDK K23 award, patients with MACS demonstrate higher incidence of fractures and report more falls and symptoms of muscle weakness. In our preliminary data we show that when assessed by a comprehensive multi-steroid panel, patients with MACS demonstrate a unique steroid signature that is similar to aging adults without adrenal adenomas. We further found that patients with MACS demonstrate lower cognition and increased frailty and increased senescence biomarkers. Our overall objective of this project is to understand the link between the abnormal steroid signature and cognitive function, overall frailty, and biomarkers of cellular senescence. In Aim 1, the domains and the extent of cognitive impairment will be characterized in patients with MACS, and the association of cognitive function to accelerated adrenal aging, as measured by the steroid metabolome will be determined. In Aim 2, the association of cognitive impairment with frailty, advanced glycation products, and biomarkers of senescence will be determined. The proposed research will take advantage of the current structure and detailed characterization of subjects enrolled as part of the K23 NIDDK award as well as another ongoing prospective study of patients with overt hypercortisolism. The exceptional resources and institutional support at Mayo Clinic, outstanding multi- disciplinary mentorship and collaborative team, will allow advancement in understanding the steroid signature associated with cognitive decline that may serve as a diagnostic and prognostic biomarker of cognitive impairment and frailty.

项目摘要/摘要 在多达50％的肾上腺腺瘤患者中诊断出轻度自主皮质醇分泌（MAC）， 影响1-2％的成年人口。 Mac是根据地塞米松后根据皮质醇异常诊断的 抑制;但是，24小时尿皮质醇浓度通常正常。正如我们最近在工作中所显示的那样 由当前NIDDK K23奖赞助的MAC患者表现出更高的骨折发病率 并报告肌肉无力的更多跌倒和症状。在我们的初步数据中，我们显示在评估时 通过综合的多类固醇小组，具有MAC的患者表现出独特的类固醇特征 类似于没有肾上腺腺瘤的成年人。我们进一步发现，患有MAC的患者证明了 较低的认知和脆弱和增加的衰老生物标志物。 该项目的总体目标是了解异常类固醇签名与 认知功能，整体脆弱和细胞衰老的生物标志物。在AIM 1中，域和程度 认知障碍将在MAC患者中进行表征，并将认知功能的关联与 将确定由类固醇代谢组测量的加速肾上腺衰老。在AIM 2中 认知障碍与脆弱，高级糖化产品和衰老生物标志物的关联 将确定。 拟议的研究将利用当前的结构和详细表征 作为K23 NIDDK奖的一部分，以及另一项正在进行的前瞻性研究 超皮质醇。梅奥诊所的卓越资源和机构支持，杰出的多种 纪律指导和协作团队将允许理解类固醇签名的进步 与认知能力下降有关，这可能是认知的诊断和预后生物标志物 障碍和脆弱。
