Hydrocortisone vs Prednisone During Recovery Following Surgical Cure for Endogenous Hypercortisolism: A Longitudinal Observational Study Introduction: Glucocorticoid withdrawal syndrome (GWS) is a constellation of symptoms that occurs after successful surgery for endogenous hypercortisolism. The objective of this study is to compare hydrocortisone versus prednisone on GWS symptoms. Methods: Study design: Single-center prospective longitudinal cohort study, 2019-2023. Participants: Adults with Cushing syndrome (CS) and mild autonomous cortisol secretion (MACS) with post-operative adrenal insufficiency treated with either hydrocortisone or prednisone for glucocorticoid replacement. Measurements: Clinical and biochemical severity scores for hypercortisolism were calculated. Quality of life (QOL) was assessed using Short Form-36 (SF-36) and Cushing QOL surveys. GWS was assessed using weekly AddiQoL surveys for the first 12 weeks after surgery. Results: Of 131 patients, 91 (69%) patients were treated with hydrocortisone and 40 (31%) with prednisone. No differences in age (median age 51 vs 53 years, P=0.62), sex (84 vs 85% women, P=0.83), etiology of hypercortisolism (ACTH-dependent: 44% vs 48%, P=0.26), clinical severity of hypercortisolism (median score 13 vs 12, P=0.97), or biochemical severity of hypercortisolism (median score of 6 in both, P=0.31) were noted between groups. When assessed at 4-, 8-, and 12-weeks post-surgery, the prevalence and trajectory of symptoms (fatigue, myalgias/arthralgias, sleep, headaches, nausea, weakness) were similar in patients treated with hydrocortisone and prednisone (P>0.05 for all). However, patients treated with prednisone were less likely to report mood changes (8.5% vs 20.9%, P= 0.004) compared to those treated with hydrocortisone. When compared to the presurgical baseline, the overall Cushing QOL score 12 weeks post-surgery improved in both groups (mean delta 8.9 vs 13.0, P=0.21). No differences in the hydrocortisone vs prednisone treatment were found in the SF-36 physical component score (mean delta of -1.7 vs 0.3, P=0.23) and SF-36 mental component score (mean delta 2.3 vs 5.0, P=0.22). Using multivariable analysis, age (estimate 0.22, P= 0.005), clinical severity score (estimate -0.73, P<0.001), female sex (estimate -5.45, P= 0.046) but not glucocorticoid type (estimate -0.06, P=0.98) were associated with the overall GWS symptom burden at 12 weeks. Conclusion: Use of prednisone after curative surgery for hypercortisolism was associated with lower mood symptoms, but did not impact the overall severity or trajectory of other symptoms associated with GWS. Baseline clinical severity of hypercortisolism, age, and female sex were associated with GWS burden. Presentation: 6/1/2024
FRI177 Cosyntropin Stimulation Testing Is More Selective Than Postoperative Day 1 Basal Cortisol for Diagnosing Secondary Adrenal Insufficiency Following Unilateral Adrenalectomy
Abstract Disclosure: S.H. Johnson: None. C. Zhang: None. P.T. Hangge: None. T.W. Yen: None. T. Shaik: None. K. Doffek: None. J.W. Findling: None. T.B. Carroll: None. D.B. Evans: None. S. Dream: None. T.S. Wang: None. Background: Secondary adrenal insufficiency (SAI) may occur in patients after unilateral adrenalectomy for adrenal-dependent hypercortisolism (HC) and/or primary aldosteronism (PA). Perioperative protocols include routine glucocorticoid replacement (GR) or selective GR based on postoperative day 1 (POD1) basal cortisol levels or cosyntropin stimulation testing (CST). This study aimed to assess if a POD1 basal cortisol level alone was predictive of an abnormal CST and the need for GR in patients following unilateral adrenalectomy for HC and/or PA. Methods: This is a single institution retrospective review of consecutive unilateral adrenalectomies performed for HC and/or PA from 9/2014-10/2022. Patients were grouped as overt hypercortisolism (OH;n=42), mild autonomous cortisol excretion (MACE;n=70), mixed PA/HC (n=22) or PA (n=73); 22 patients with PA did not have preoperative evaluation for HC. Preoperative morning cortisol after low-dose dexamethasone suppression testing (DST), was used to define MACE (1.8-4.9 µg/dL) and OH (≥5.0). POD1 CST was performed for all patients with HC and prior to 2021, all patients with PA. SAI was defined as basal cortisol ≤5 or stimulated ≤14 (≤18 before 4/2017). Receiver operating characteristic (ROC) curves and sensitivity analyses were performed to assess the sensitivity (SN) and specificity (SP) of cutoffs within the range of observed basal cortisol levels in predicting an abnormal CST and need for GR. Results: Of 207 patients, 152 had POD1 CST (93% OH, 96% MACE, 73% PA/HC, 41% PA). Of these, 80 (53%) had SAI (67% OH, 55% MACE, 44% PA/HC, and 33% PA). Of the 10 patients with PA and SAI, 5 did not have preoperative testing for HC. Overall, 81 patients were discharged on GR. Median (interquartile range [IQR]) duration of GR was 246 (127,557), 55 (38,207), 74 (16,185), and 26 (15,36) days in patients with OH, MACE, PA/HC, and PA, respectively. At a median follow-up of 142 days (IQR 42,617), 12 patients (5 OH, 6 MACE, 1 PA/HC) remained on GR. The SN/SP of a basal cortisol ≤10 in predicting GR was 92%/77% in patients with OH and 94%/73% of patients with MACE. Compared to initiation of GR based on basal cortisol ≤10, CST identified 4 patients with SAI in the combined OH and MACE cohorts who would not have received GR, and 11 in the combined cohort who did not require GR. For patients with PA and PA/HC, a basal cortisol ≤10 had SN of 100% and SP of 85% and 67%, respectively. The optimal basal cortisol for predicting SAI in patients with PA/HC was ≤5 (SN,SP 100%). Area under the curve for all ROC curves was >0.9. Conclusion: These results demonstrate that in patients who underwent unilateral adrenalectomy for HC, PA, or mixed PA/HC, POD1 CST improved identification of patients at risk for SAI compared to basal cortisol levels alone. While basal cortisol levels alone may be considered in patients with PA or mixed HC/PA, all other patients with HC should have POD1 CST to determine need for postoperative GR.

Stricker: None. I. Bancos: None. Background: Patients with mild autonomous cortisol secretion (MACS) have impaired cognition compared to patients with non-functioning adrenal adenomas. However, the impact of adrenalectomy on cognitive function in patients with MACS is unclear. Objective: To determine the impact of adrenalectomy on cognitive function in patients with MACS. Methods: Single-center prospective longitudinal study of adults with MACS. MACS was defined as serum cortisol >1.8 mcg/dL after the 1 mg dexamethasone suppression test (DST) in patients with adrenal adenomas without any overt features of hypercortisolism. Patients underwent cognitive evaluation using the standardized National Institute of Health (NIH) Toolbox Cognition Battery (7 tests of attention, episodic and working memory, language, executive function, cognitive flexibility, and processing speed) prior to adrenalectomy and at follow-up at least 10 months post-surgery. Fully corrected T-scores for age, sex, education, and race were compared using a paired t-test before and after adrenalectomy. A T-score of 50 is average performance (SD of 10). Total cognition is composite of fluid cognition (executive function, episodic memory, cognitive flexibility, working memory and processing speed) and crystallized cognition (language and vocabulary). Results: A total of 27 patients with MACS (median age 59.7 years, IQR 51.4-66.9, 17, 63% women) underwent cognitive evaluation prior to and at a median of 1.5 years (IQR, 1.1- 2.0) after adrenalectomy. Before surgery, median post-DST cortisol was 3.8 mcg/dL (IQR, 2.7-6.4) mcg/dL. Of the 27 patients, 21 (78%) patients developed post-operative adrenal insufficiency with 6 (21%) patients still requiring still requiring glucocorticoid replacement at the time of the last follow-up. At baseline, the mean total composite T-score was 50.7 (9.3), with fluid composite T-score of 49.9 (9.4) and crystallized composite T-score of 51.3 (8.7). Following adrenalectomy, all three composite T-scores improved compared to baseline. The crystallized composite T-score (composed of language and vocabulary) increased by a mean of 3.7 (5.5), P=0.001, the fluid composite T-score (composed of episodic, executive, working memory, cognitive flexibility, and processing speed) increased by a mean of 3.1 (8.3), P=0.068, and the total composite T-score improved by a mean of 3.9 (6.2), P=0.004. Conclusion: We showed that adrenalectomy in patients with MACS is associated with improvement in cognition. However, as test results may improve with practice (i.e., improvement due to taking the test the second time), to determine whether the improvements observed represent a reliable change in cognition, the next step is to evaluate for cognition score changes in referent subjects.

THU606 Cognitive Impairment In Patients With Mild Autonomous Cortisol Secretion: A Cross-sectional Study
Abstract Disclosure: J. Saini: None. R. Nathani: None. S. Singh: None. K. Thangamuthu: None. M. Suresh: None. C. Zhang: None. A.L. Ebbehøj: None. M. Thomas: None. V. Fell: None. E. Atkinson: None. S. Achenbach: None. N. Stricker: None. I. Bancos: None. Introduction: While patients with overt Cushing syndrome are reported to have impaired cognition, the impact of milder, long-standing hypercortisolism on cognition is incompletely characterized. Objective: To determine the impact of MACS on cognition as compared to age, sex, and education-matched referent subjects. Methods: We conducted a single-center cross-sectional study of adults with MACS and referent subjects. MACS was defined as serum cortisol>1.8 mcg/dL after 1 mg dexamethasone suppression test (DST) in patients with adrenal incidentalomas. Referent subjects were included if they had abdominal imaging and had no adrenal disorders. Exclusion criteria were malignancy and exogenous glucocorticoid use within 1 year. All participants underwent a cognitive evaluation using the NIH Toolbox Cognition Battery between 1/2019 to 7/2022. NIH Toolbox assesses 8 cognitive domains using 7 tests and yields 3 composite scores: fluid cognition (executive function, episodic memory, cognitive flexibility, working memory, and processing speed), crystallized cognition (language and vocabulary), and total composite cognition (composite of all). Results are given in fully corrected T scores (adjusted for age, sex, race, and education) with an average of 50 and a standard deviation (SD) of 10. A subgroup analysis was performed based on DST cortisol. The Kruskal-Wallis test was used to compare scores between groups. Results: A total of 94 patients with MACS (median age 57.2 years, IQR 47.8-66.5, 70% women) and 94 referent subjects (median age 58 years, IQR 49.1-66.4, 70% women) were included. The median post-DST cortisol in patients with MACS was 3.3 mcg/dL (IQR, 2.4-6.2). The mean (SD) total composite T-score was lower in patients with MACS vs referent subjects (51 (9.1) vs 56.3 (9.3), P<0.001). Patients with MACS demonstrated lower mean fluid composite T-score when compared to referent subjects (49.5 (10.4) vs 56.9 (9.7), P<0.001). However, mean crystallized composite T-scores were similar in patients with MACS and referent subjects (52.3 (8.1) vs 53.9 (9.6), P=0.342). A subgroup analysis of patients with post-DST cortisol <3 mcg/dL (n=40) vs patients with post-DST cortisol >3 mcg/dL (n=54) did not show any differences in the total, fluid, or crystalized composite scores. Conclusion: Patients with MACS demonstrate lower cognitive performances than a referent group suggesting MACS has a subtle impact on cognitive functioning. The pattern of cognitive impairment in patients with MACS is similar to that seen with normal cognitive aging: impaired fluid cognitions and unaffected crystallized cognition). Cognitive performance did not differ based on the degree of MACS suggesting that in the absence of overt features of hypercortisolism, the degree of MACS is less important than the presence of MACS.

Risk of Mental and Sleep Disorders After the Diagnosis of Adrenal Adenomas: A Population-Based Cohort Study
Abstract Background: Adrenal adenomas are incidentally diagnosed in 7% of adults undergoing abdominal imaging. Mild autonomous cortisol secretion is present in 50% of adrenal adenomas, and even “nonfunctioning” adrenal adenomas demonstrate abnormal steroid profile. We aimed to 1) investigate the prevalence of mental and sleep disorders in patients with adrenal adenomas and to 2) determine the risk of mental and sleep disorders after the diagnosis of adrenal adenoma in patients compared to the referent subjects from the same population Methods: Using a medical records linkage system, we identified adult patients living in the Olmsted County, MN diagnosed with an adrenal adenoma during 1995–2017. Patients with overt hormone excess were excluded. Every patient with adenoma was matched by sex and age to a referent subject from the same population. Subjects were followed until death or end of the study. Mental health related comorbidities and sleep disorders were assessed at baseline and during follow up. Results: Our cohort included 1004 patients with adrenal adenomas and 1004 referent subjects (58% women, median age of 63 years). Patients were more likely to smoke (70% vs 54%, p <0.001) and had a higher BMI (30 kg/m2 vs 28 kg/m2, p < 0.001). Within 5 years prior to the index date (diagnosis of adenoma), and after adjusting for BMI and smoking, patients demonstrated a higher prevalence of depression (Odds ratio, OR of 1.3 (CI95% 1.1–1.6), p=0.02), anxiety (OR of 1.4 (CI95% 1.1–1.8, p=0.003), substance abuse disorders (OR of 2.4 (CI 95% 1.7–3.4), p<0.001), but not insomnia (OR of 1.2 (CI95% 0.9–1.7) and sleep related breathing disorders (OR of 1.3 (CI 95% 0.9–1.7). During follow-up, starting 1 year after the diagnosis, patients demonstrated a higher risk of new onset depression (HR of 1.9, CI95%1.5–2.4), anxiety (HR of 1.5,CI95% 1.2–1.9), schizophrenia (HR of 1.7, CI95% 1.2–2.4), and substance abuse disorders (HR of 1.6, CI95% 1.2–2.0). Risk of sleep disorders 1 year after diagnosis was also high for insomnia (HR of 1.4, CI95% 1.1–1.9), sleep-related breathing disorders (HR of 1.8, CI95% 1.4–2.3), hypersomnias of central origin (HR of 2.0, CI95%1.04–3.96), parasomnias (HR of 2.4, CI95%1.2–4.7), and sleep-related movement disorders(HR of 1.9, CI95%1.3–2.6). Conclusion: Patients with adenomas are at increased risk for mental and sleep disorders, possibly explained by the underlying subtle cortisol secretion. Further prospective studies with an in-depth characterization of both hormonal secretion and mental/sleep disorders are needed. Reversibility or improvement of mental health and sleep disorders with adrenalectomy should be investigated.
SAT-176 Epidemiology of Adrenal Tumors: A Population Based Study of 1287 Patients
Abstract Background: Adrenal tumors are reported in 5% of adults, with malignancy rates in 1–12%, and rates of overt hormonal excess in 1–15 %. However, most estimates originate from convenience samples. Our objective was to determine the incidence, prevalence and clinical presentation of adrenal tumors in a population-based setting. Methods: We used a centralized epidemiologic database to identify patients diagnosed with adrenal tumors in a local community 1995 to 2017. The database is a unique medical records linkage system that allows access to hospital and community medical records for local residents (population 137,000). We calculated incidence rates (IR) as the number of new patients diagnosed while living in the study area, and prevalence as the number of patients living in the study area on Dec 31 2017. IR and prevalence were sex- and age-adjusted to the 2010 US Census population. Results: Of 1,287 patients diagnosed with adrenal tumor, the median age of diagnosis was 62 years (IQR 52–72), 713 (55%) were women, and 13 (1%) were younger than 18 years at diagnosis. IR was highest in patients >65 YO, followed by patients 40–64 YO, 18–39 YO and <18 YO (142 vs 66 vs 9 vs 2 per 100,000 persons years). IR per 100,000 increased from 4.4 (CI95% 0.3–8.6) in 1995 to 47.8 (CI95% 36.9–58.7) in 2017. Overall prevalence in the population was 0.53% in 2017, ranging from 0.01% among 0–17 YO to 1.9% among +65 YO. Malignant adrenal mass was diagnosed in 8.7% patients (4 patients with adrenal cortical carcinoma (0.3%) and 108 (8.4%) patients with other malignant mass). Pheochromocytoma was diagnosed in 11 (1.1%) patients and benign adrenal mass was diagnosed in 1,175 (90.2%) patients (1,076 (83.6%) with adrenal adenoma and 85 (6.6%) with other benign mass). Median tumor size was 15 mm (range 5–255), and 184 (14%) of patients had bilateral tumors. Only 255 (20%) patients had dexamethasone suppression test, 93 (36%) with cortisol>1.8 mcg/dl. Of 1,076 adrenal adenomas, 53 (4.9%) had overt hormone excess, 140 (13%) had nonfunctioning adrenal adenomas, and 88 (8.2%) had mild autonomous cortisol secretion. Hormonal work up for was incomplete in 795 (73.9%) adenomas. Patients discovered incidentally (1,050, 81.6%) had a lower rate of malignancy and hormone excess (5.3% vs 52% of patients with non-incidental discovery, p <0.001). Rate of malignancy was highest in children (67% vs 8% >18YO, p<0.001), bilateral tumors (16% vs 8% unilateral, p<0.001), tumors ≥4 cm (33% vs 7% in < 4 cm, p<0.001). Conclusion: IR of adrenal tumors increased 10-fold since 1995, and was highest in patients >65 YO. 8.7% of tumors were malignant, with a majority represented by malignant adrenal tumors other than adrenal cortical carcinoma. The risk of malignancy was highest in non-incidental discovery, children, and tumors > 4 cm. Overt hormone excess was diagnosed in 4.5% of patients. The majority of patients with adrenal adenomas had a suboptimal work up for hormone excess.
MON-219 Prevalence and Incidence of Fractures in Patients with Adrenal Adenomas: A Population-Based Study of 1003 Patients
Abstract Background: Adrenal adenoma is reported in around 5% of adults undergoing cross-sectional imaging. Although most adenomas are considered non-functioning (NFAT), up to 48% present with mild autonomous cortisol secretion (MACS). Several studies reported increased prevalence and incidence of vertebral fractures in MACS; however conclusions are limited by small sample size, selection bias, inadequate reference population and length of follow up. Objective: To determine the prevalence and incidence of site-specific fragility fractures in a population-based cohort of patients with adrenal adenomas. Methods: Residents of local community with a radiographic diagnosis of adrenal adenoma between 1995 and 2017 were identified using a centralized epidemiologic database and matched with reference subjects for sex and age. All subjects were followed through 2017, until death or migration from the community. MACS was diagnosed based on cortisol level ≥1.8 mcg/dl after overnight 1mg dexamethasone suppression, NFAT based on cortisol level <1.8 mcg/dl, and patients not tested with dexamethasone were considered as adenoma with unknown cortisol secretion (AUCS). Results: Of 1003 patients with adrenal adenomas (581 women (58%), median age of diagnosis 63 years (20–96)), 136 (14%) were diagnosed with NFAT, 86 (9%) with MACS, and 781(78%) with AUCS. At the time of diagnosis, patients had higher BMI (median 30 vs 28 kg/m2, p<0.001), and higher prevalence of tobacco use (70% vs 54%, p<0.001) than reference subjects. Of 154 patients and 113 reference subjects with BMD available at baseline, patients had a higher median BMD at the total hips (0.93 vs 0.89, p=0.02) but similar median BMD at lumbar spine (1.05 vs 1.03, p=0.49) when compared to reference subjects. However, patients had a higher prevalence of fractures than reference subjects (any fracture: 50% vs 42%, p<0.001, vertebral fracture: 6.5% vs 3.7%, P=0.004). When adjusted for age, sex, and prior history of fracture, patients with adenoma had HR of 1.24 (CI 95% 1.04–1.48) for developing a new fracture and HR of 1.18 (CI 95% 0.97–1.44) when also adjusted for BMI and smoking. Subgroup analysis demonstrated that the prevalence of fractures at the time of diagnosis was higher in all 3 subgroups at any fragility fracture site when compared to reference subjects (NFAT: 44% vs 37%, MACS: 48% vs 43%, AUCS: 51% vs 43%); patients with MACS had the highest incidence of new fracture after 5 years of follow up when compared to AUCS and NFAT (cumulative incidence: MACS 25% vs NFAT 19% vs AUCS 16%), though the differences were not significant. Conclusions: Patients with adrenal adenomas have higher prevalence of fractures at the time of diagnosis. During follow up, patients with adenoma have a higher incidence of fractures even when adjusted for sex, age, and prior history of fracture, possibly due to underlying undiagnosed abnormal cortisol secretion.
