Abstract Context Limited data are available on quality of life (QoL) and adrenal crises in patients with immune checkpoint inhibitor–induced secondary adrenal insufficiency (ICI-SAI). Objective To (1) characterize the presentation, management, and outcomes of patients with ICI-SAI; (2) compare outcomes of ICI-SAI with other etiologies of secondary adrenal insufficiency (oSAI); and (3) identify variables associated with QoL and adrenal crisis. Methods In this single-center cross-sectional study, adults with ICI-SAI or oSAI (2018-2025) completed questionnaires assessing symptoms, management, adrenal crises, and the Addison’s Disease–Specific QoL survey (AddiQoL); outcomes included AddiQoL score and adrenal crisis events. Results Patients with ICI-SAI (n = 109) were older (median age 66 vs 60 years), more often women (59% vs 43%), and more frequently diagnosed within 1 year of symptom onset (88% vs 42%, P < .001), compared to patients with oSAI (n = 139). Patients with ICI-SAI had higher AddiQoL scores (median 87 vs 85, P = .020). In a multivariable analysis of age, sex, glucocorticoid dose and type, insurance support, and duration of SAI, ICI-SAI remained independently associated with higher AddiQoL (estimate 5.4, P = .010). The prevalence of reported adrenal crises within the prior year was similar between groups (15% vs 14%, P = .782). In a multivariable analysis, higher AddiQoL scores were independently associated with lower odds of adrenal crisis (OR 0.57; 95% CI 0.42-0.76). Conclusion Patients with ICI-SAI report better QoL compared with patients with other causes of SAI, despite similar adrenal crisis rates. These differences may be related to earlier diagnosis and differing clinical contexts, underscoring the importance of timeline recognition and patient-centered management.

Abstract Context The clinical relevance of etiologic concordance and temporal presentation in bilateral adrenal masses remains poorly defined, creating uncertainty in diagnostic evaluation and management. Objective To characterize the etiologic spectrum of bilateral adrenal masses, evaluate patterns by concordance and synchronicity, and identify predictors of discordance and malignant or pheochromocytoma contralateral lesions. Design Retrospective cohort study (2010-2025). Setting Tertiary referral center. Participants Adults with bilateral adrenal masses. Main Outcome Measures Etiology, concordance, synchronicity, interval to contralateral lesion, and factors associated with discordance and malignant or pheochromocytoma contralateral lesions. Results Among 1035 patients (median age 59.6 years; 51% women), 85% had concordant and 15% discordant etiologies. Concordant cases were predominantly bilateral benign cortical lesions (76%), whereas discordant cases were heterogeneous (benign 35%, malignant 31%, and indeterminate 34%). Presentation was synchronous in 84% and asynchronous in 16%, with a median interval of 45 months (interquartile range 15-87). Asynchronous disease was associated with higher discordance (23% vs 13%, P = .001) and greater prevalence of malignant lesions (bilateral malignant: 17% vs 7%; discordant malignant: 8% vs 4%; overall P < .001). Among asynchronous cases, shorter interval to contralateral lesion (<2 vs ≥5 years) was independently associated with malignant or pheochromocytoma etiology (adjusted odds ratio [OR] 2.63, 95% CI 1.01-6.85), as was larger tumor size (adjusted OR 1.06 per mm, 95% CI 1.02-1.09). Conclusion Most bilateral adrenal masses are benign and concordant; however, discordant or asynchronous disease identifies a higher-risk subgroup enriched for malignancy. Early contralateral lesion development and larger tumor size are key risk factors.

Abstract Context Bilateral adrenalectomy (BLA) and autoimmune adrenal insufficiency (AAI) are 2 major causes of primary adrenal insufficiency (PAI). Comparative data between etiologies are limited. Objective To compare management, quality of life (QoL), and frequency of adrenal crises between participants post-BLA vs AAI. Methods We conducted a dual-center, cross-sectional study of adults with AAI or BLA between 2018 and 2025. All participants completed questionnaires on management, adrenal crises, and the Addison Disease-specific QoL Questionnaire (AddiQoL). Results Of 343 participants, 203 had AAI (median age 54 years, 72% women) and 139 had BLA (median age 57 years, 76% women). AddiQoL scores were similar between participants with AAI and BLA (median 84 vs 83, P = .947), but better in participants post-BLA for pheochromocytoma versus hypercortisolism (median 88 vs 81, P = .031). Participants with AAI reported a higher number of adrenal crises within the past year than those post-BLA (25% vs 13%, P = .022). In multivariable analyses of age, sex, glucocorticoid dose and type, PAI type, AddiQoL score, and autoimmune comorbidities, only PAI type was associated with higher number of reported adrenal crisis within the last year (AAI vs BLA: odds ratios of 2.1-2.2, P < .05 for all models). Conclusion QoL was comparable between participants with AAI and BLA, though patients post-BLA for pheochromocytoma reported better QoL than patients post-BLA for hypercortisolism. Adrenal crises were more common in participants with AAI than those post-BLA, a finding that was not explained by patients’ glucocorticoid management, underscoring the need for tailored crisis prevention strategies.

Abstract Context Patients with mild autonomous cortisol secretion (MACS) have higher rates of vertebral fractures compared to patients with non-functioning adrenal nodules, yet bone density is not always reduced. Objective To characterize the effect of MACS on bone density, metabolism, and microstructure as measured by high-resolution peripheral quantitative computed tomography (HR-pQCT). Design Cross-sectional study, 2019-2022 Setting Tertiary referral center Participants Seventy-five patients with MACS and 75 age-, sex-, and gonadal status–matched referent subjects. Measurements Bone turnover markers, dual-energy x-ray absorptiometry (DXA) scan, and HR-pQCT. Outcomes Areal and volumetric bone mineral density (aBMD, vBMD), trabecular bone score (TBS), microstructural parameters including trabecular bone volume to total volume (BV/TV) ratio. Results While no differences in aBMD were observed at any skeletal site, patients with MACS had decreased TBS (1.389 vs 1.475, P < .001) and lower osteocalcin concentration (17.1 vs 19.5 ng/mL, P = .030) than referent subjects. On HR-pQCT at the tibia, patients with MACS had reduced trabecular BV/TV (0.220 vs 0.233, P = .015) compared to referent subjects. On multivariable analysis, MACS was associated with lower TBS (odds ratio [OR] per SD decrease 2.87 [1.65-5.00]), lower trabecular BV/TV at the radius (OR per SD decrease 2.58 [1.33-5.00]), and lower trabecular BV/TV at the tibia (OR per SD decrease 4.06 [2.10-7.86]). Conclusion Patients with MACS have microstructural deterioration that may not be evident on routine DXA aBMD testing.

Abstract Prognostic indices such as the CLL International Prognostic Index (CLL-IPI) and the International Prognostic Score for Early-stage CLL (IPS-E) can predict time to first treatment (TTFT) in patients with early-stage CLL. Their ability to predict risk of infection - a leading contributor to morbidity and mortality in CLL - remains uncertain. The CLL-TIM is a machine-learning model developed in Europe that integrates clinical, laboratory, and infection-related data to predict TTFT or infection risk within 2-years of diagnosis, Receiver Operating Characteristic - Area Under the Curve (ROC-AUC) 0.74; Agius et al., Nat Comm 11, 363 2020. We conducted the first validation of CLL-TIM in a US cohort of newly diagnosed CLL patients and compared its performance with the CLL-IPI and IPS-E indices. Adults with newly diagnosed CLL (2000-2020) were identified through the Rochester Epidemiology Project using International Classification of Disease (ICD) codes; all diagnoses were confirmed. We replicated the variable selection from the original CLL-TIM model and applied it to our cohort. The primary endpoint was a 2-year composite of either TTFT or incident infection (defined as having blood cultures drawn). Model performance was evaluated using ROC-AUC consistent with the original CLL-TIM methods. CLL-IPI and IPS-E performance was assessed using time-dependent ROC-AUC; pairwise differences in discrimination were tested using DeLong. We identified 454 CLL patients with a median age of 72 years [range, 30-97], 166 (37%) were female, Rai Stage was 0-II in 399 (92%) patients. IGHV genes were unmutated in 130/305 (42%) patients and TP53 disruption (either del17p by FISH or TP53 mutation) was present in 24/329 (8%) patients. At 2-years, 55 (12%) patients received CLL therapy, and 56 (12%) patients had an infection. The 2-year composite endpoint was observed in 94 (21%) patients. The ROC-AUC was 0.74 (95% CI 0.68-0.80) for CLL-TIM, 0.69 for CLL-IPI (95% CI 0.63-0.75, p=0.11 compared to CLL-TIM) , and 0.68 for IPS-E (95% CI 0.62-0.74, p=0.02 compared to CLL-TIM). We also evaluated the ROC-AUC using all the prognostic models for each individual endpoints. The corresponding ROC-AUC for TTFT at 2 years were 0.79, 0.74, and 0.76 for CLL-TIM, CLL-IPI, and IPS-E, respectively; and for infection at 2 years were 0.68, 0.57, and 0.52, respectively. This is the first validation of the CLL-TIM in a US-based cohort of newly diagnosed CLL patients. Although the CLL-TIM model exceeded the minimally meaningful discrimination threshold (AUC >0.7) for individual patient-level risk prediction, there was no statistical difference in AUC between CLL-TIM and CLL-IPI, suggesting either model can predict the composite endpoint at 2 years. Most of the observed discrimination was driven by prediction of TTFT rather than infection, underscoring the need to develop more infection-specific risk models for newly diagnosed CLL.

Abstract Context Data on cognition in patients with primary aldosteronism (PA) are scarce. Mild autonomous cortisol secretion (MACS), defined based on post-dexamethasone cortisol >1.8 mcg/dL, is diagnosed in up to 30% of patients with PA. Objectives (1) Assess cognition in patients with PA vs referent subjects with hypertension and (2) determine differences in cognition between patients with PA and those with MACS. Methods A prospective, cross-sectional study, 2019-2023. Cognition was assessed by National Institute of Health Toolbox Cognition Battery and reported as T-scores corrected for age, sex, race, and education. Only subjects with hypertension were included. Results Cognitive assessment was performed in 52 patients with PA (including 11 patients with both PA and MACS, median age of 51.0 years, 30 (57.7%) women), 47 patients with MACS (median age of 57.0 years, 31 (66.0%) women), and 52 referent subjects (median age of 66.1 years, 30 (57.7%) women). When compared to referents, and after adjusting for age, smoking, systolic blood pressure, and alcohol use, patients with PA had lower total cognition (β = −5.7, P = .023), notably fluid cognition (β = −6.8, P = .017), including attention and executive function (β = −5.6, P = .012) and cognitive flexibility and executive function (β = −8.2, P = .006). When compared to patients with MACS, patients with PA had a higher processing speed (β = 9.0, P = .003). No differences in cognition were found between patients with PA with and without MACS. Conclusion Patients with PA demonstrated lower cognition compared with referents and processing speed compared with MACS. Future studies should characterize the impact of MACS on the cognition of patients with PA.

Objective The objective of this study was to investigate the association between dual seropositive, single seropositive, and seronegative rheumatoid arthritis (RA) with radiographic erosions, disease flares, and death. Methods We performed a retrospective, population‐based study of residents in Southern Minnesota with incident RA who fulfilled criteria for RA in 2003 to 2019. Radiographic erosions and flares were evaluated within one year of incident RA. All‐cause mortality was obtained from medical records and death certificates. Cox models adjusted for age, sex, smoking status, year of incident RA, and comorbidities were used. Results The study included 1,373 patients with RA. At RA incidence, 37% were dual seropositive, 13% seropositive for anti–cyclic citrullinated protein (anti‐CCP) only, 12% seropositive for rheumatoid factor (RF) only, and 38% seronegative. The highest proportion of radiographic erosions before or within one year of RA incidence was in the dual seropositive (31%) and lowest in those seropositive for anti‐CCP only (13%). Flares occurred in 69% of the dual seropositive and 51% of the seropositive for anti‐CCP only within the first year of RA incidence. Those seropositive for RF only had over a two‐fold increase in mortality rates compared with the seronegatives (adjusted hazard ratio [aHR] 2.18, 95% confidence interval [CI] 1.47–3.24). In contrast, the dual seropositives had only a >50% increase in mortality rates (aHR 1.66, 95% CI 1.21–2.28), and those seropositive only for anti‐CCP had a >30% increase in mortality rates (aHR 1.32, 95% CI 0.83–2.11). Conclusion Patients with RA seropositive for RF only have an increase in mortality rates compared with patients who are dual seronegative. RF positivity could be an indicator of inflammation that requires pharmacologic treatment to decrease mortality rates.

Abstract Objective Evidence on the duration of post-operative adrenal insufficiency (AI) in patients with endogenous hypercortisolism is scarce. We sought to determine the duration of post-operative AI and to identify factors associated with the duration of AI in patients undergoing surgery for endogenous hypercortisolism. Methods We conducted a single-center prospective cohort study, 2019-2025, of patients with endogenous hypercortisolism [Cushing syndrome (CS) or mild autonomous cortisol secretion (MACS)] treated with surgery. Associations of demographics, body mass index (BMI), clinical, and biochemical hypercortisolism severity, subtype of hypercortisolism, pre-surgical hypercortisolism duration, glucocorticoid type, and nadir cortisol in relation to duration of AI were investigated. Results The 242 patients [41% MACS, 46% pituitary CS, 12% adrenal CS, 1% ectopic CS, median age 50 years (IQR: 40-60), 85% women] who developed postsurgical AI were followed for a median duration of 13.7 months (IQR 7.2-26.3). The median time to recovery of AI was shorter in MACS vs. overt CS (3.9 months (95% CI: 3.3-6.2) vs. 13.5 months (95% CI 11.3-18.3), P value < .001). On multivariable analysis adjusting for age, sex, BMI, and glucocorticoid type, moderate to severe biochemical severity score (β = 11, P value < .001) and moderate to severe clinical severity score (β=8.7, P < .001), were associated with a longer duration of AI. Conclusions Baseline clinical and biochemical hypercortisolism severity scores may inform individualized counseling on post-operative AI duration in patients treated for CS and MACS.

Objective The purpose of this study was to determine the cumulative incidence of diagnosis switching, drug‐free remission, and initiation of a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD) in individuals with seronegative rheumatoid arthritis (RA). Methods Adult residents of Olmsted County, Minnesota, with incident seronegative (rheumatoid factor negative/anti–cyclic citrullinated peptide antibody negative) RA meeting the 1987 and/or 2010 American College of Rheumatology classification criteria were included. Data were collected from January 1, 2005, to December 31, 2023, through manual chart review. Drug‐free remission was defined as a period of at least six months where the individual was no longer taking treatment for RA and did not have evidence of active inflammatory arthritis upon evaluation by a rheumatologist. We calculated the 10‐year cumulative incidence of a change in diagnosis, adjusting for the competing risk of death, and of drug‐free remission and initiation of a b/tsDMARD, adjusting for the competing risks of death or change in diagnosis. Results A total of 176 individuals with seronegative RA (68% women) were included. The 10‐year cumulative incidence of a change in diagnosis was 12.8% (95% confidence interval [CI] 8.7%–18.9%). The most common change in diagnosis was to spondyloarthritis (4%). The 10‐year cumulative incidence of drug‐free remission and initiation of a b/tsDMARD was 26.6% (95% CI 20.7%–34.2%) and 19.9% (95% CI 14.7%–26.9%), respectively. Over a median follow‐up of 11.8 years, 49 individuals entered drug‐free remission. Conclusion After initial diagnosis of seronegative RA, about 13% of individuals had a change in diagnosis and a quarter experienced drug‐free remission within 10 years.

Abstract Background: The synergistic mechanisms of BCL-2 inhibitors and CD20-directed antibodies in the treatment of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) often lead to deep and durable responses. Although the use of venetoclax-obinutuzumab (Ven-O) in the frontline setting (1L) for CLL/SLL has led to a paradigm shift in the disease management, there are limited data on its efficacy in the relapsed/refractory (R/R) setting. In this study, we evaluated the efficacy and safety of Ven-O in both 1L and R/R CLL among patients treated outside the context of clinical trials at our institution. Methods We used the Mayo Clinic CLL Database to identify patients with CLL who were treated with Ven-O, both in 1L and R/R settings. Patients seen at Mayo Clinic Rochester between 2017 and 2025 were included. Overall survival (OS) was calculated from date of Ven-O initiation until last known alive date. Event-free survival (EFS) was calculated from date of Ven-O initiation until the next line of treatment or last known alive date. Kaplan-Meier methods estimated EFS and OS rates at 1, 3, and 5 years. Cox proportional hazards models were used to explore the association between baseline factors and EFS and OS; results are reported as hazard ratios (HR) and 95% confidence intervals (95%CI). Finally, we compared the OS to the age- and sex-matched general population of the state of Minnesota. Results A total of 154 patients (91 1L, 63 R/R) were included in the study. The median age was 68 years (69 1L, 68 R/R), and 68% were male (64% 1L, 73% R/R). Overall, TP53 disruptions (either del17p by FISH or TP53 mutation) were noted in 22 (15%) patients (9% 1L, 23% R/R). CLL FISH findings demonstrated del11q in 24 (19%) patients (19% 1L, 18% R/R), del13q in 46 (36%) patients (36% 1L, 36% R/R), and trisomy 12 in 21 (16%) patients (16% 1L, 18% R/R). IGHV genes were unmutated in 95 (68%) patients (60% 1L, 80% R/R). The CLL-IPI risk score was high in 54 (51%) patients (51% 1L, 53% R/R) and very-high in 18 (17%) patients (8% 1L, 34% R/R). A total of 121 (89%) patients completed planned treatment (1 year of venetoclax in 73 [90%] 1L and 2 years of venetoclax in 48 [87%] R/R). Median follow-up for the entire cohort was 1.8 years (2.2 1L, 1.5 R/R). Neither median EFS nor OS was reached for the overall cohort or within the 1L and R/R subgroups. The 1, 3, and 5-year EFS estimates for the overall cohort were 91% (86-96%), 85% (78-92%), and 67% (51-89%), respectively; corresponding EFS values for the 1L subgroup were 95% (91-100%), 89% (82-98%), and 67% (47-95%), respectively; and for the R/R subgroup were 85% (76-95%), 77% (65-92%), and 77% (65-92%), respectively. The 1, 3, and 5-year OS estimates were 98% (95-100%), 95% (91-99%), and 88% (76%-100%), respectively; corresponding OS values for the 1L subgroup were 99% (96-100%), 97% (94-100%), and 97% (94-100%) and for the R/R subgroup were 96% (91-100%), 91% (82-100%), and 61% (27-100%), respectively. Univariable analyses showed that TP53 disruption was associated with shorter EFS (HR 3.8, 95%CI 1.4-10.2, p=0.01), although IGHV mutation status was not associated with shorter EFS. A higher level of serum beta-2 microglobulin (HR 1.27, 95%CI 1.01-1.59, p=0.04) and R/R status (HR 4.9, 95%CI 0.9-25.8, p=0.06) were associated with a shorter OS. Interestingly, TP53 mutation status and IGHV mutation status were not associated with inferior OS. There was no difference in the observed and expected OS for both the 1L (p-0.23) and R/R (p=0.14) Ven-O treated cohorts compared to the age- and sex-matched general population of the state of Minnesota. Conclusions Our study shows that Ven-O is a well-tolerated regimen with demonstration of durable treatment responses both in the 1L and R/R groups, when used outside the context of a clinical trial. To the best of our knowledge, these data for the first time demonstrate no difference in OS of patients treated with Ven-O compared to age- and sex-matched general population, in both the 1L and R/R settings.
