Objective The aim of this study was to compare infection‐related hospitalization risk among patients with nonrenal systemic lupus erythematosus initiating commonly used immunosuppressants. Methods We emulated a target trial using Optum Labs Data Warehouse claims to compare the risk of infection‐related hospitalization among patients initiating azathioprine, belimumab, methotrexate, or mycophenolic acid analogues (MPAAs) between March 2011 and September 2023. We excluded patients with prior lupus nephritis, solid‐organ or bone marrow transplantation, or rituximab/cyclophosphamide exposure. The primary outcome was time to first infection‐related hospitalization using intention‐to‐treat (ITT) and per‐protocol (PP) analyses. We applied inverse probability of treatment weighting to account for baseline covariates and fitted marginal structural Cox models incorporating time‐varying monthly glucocorticoid dose during follow‐up. Results Among 6,168 patients, 24‐month cumulative incidence of infection‐related hospitalization was 10% (95% confidence interval [CI] 8–12) for azathioprine, 8% (95% CI 5–10) for belimumab, 10% (95% CI 8–11) for methotrexate, and 13% (95% CI 10–15) for MPAAs. In ITT analyses, MPAAs had higher risk than belimumab (hazard ratio [HR] 1.55, 95% CI 1.07–2.25) and methotrexate (HR 1.32, 95% CI 1.04–1.68). In PP analyses, azathioprine (HR 2.04, 95% CI 1.01–4.16) and MPAAs (HR 2.27, 95% CI 1.11–4.62) had higher risk compared with belimumab. After accounting for time‐varying monthly glucocorticoid dose, between‐treatment differences were no longer significant. Conclusion Initial differences in the infection‐related hospitalization risk were attenuated after accounting for time‐varying glucocorticoid exposure. These findings highlight glucocorticoid exposure as an important factor associated with serious infection risk while recognizing that postbaseline glucocorticoid use may reflect both evolving disease activity and a pathway through which therapies influence infection risk. image

Background Menopause-related symptoms are common but undertreated. Digital tools that support symptom assessment and patient education may improve engagement. Objective To assess whether a previsit digital menopause symptom assessment and education tool increased treatment initiation and patient engagement compared to an educational pamphlet. Design Women aged 45–55 years with upcoming primary care appointments were invited to participate. Those with a total Menopause Rating Scale (MRS) score ≥5 indicating bothersome menopause symptoms were included. Participants were randomized to a digital menopause symptom assessment tool or a digital educational pamphlet and completed a post-visit survey (NCT06919887). Participants Of the 14,726 women invited to participate between May 12, 2025, and December 5, 2025, there were 653 (4.4%) enrolled that met eligibility criteria. Interventions Randomized to an mHealth app called emmii or a standard digital menopause educational pamphlet. Main measures Menopause treatment initiation within 30 days of the clinical visit was assessed by electronic health data. Baseline and post-visit surveys were collected assessing patient experience, engagement, and perceived usefulness. Rates of menopause hormone therapy (HT) prescribing were compared with a reference population of nonparticipants aged 45–55 who had a primary care appointment at Mayo Clinic during the same period and received no study education materials. Key results Of 653 participants enrolled and randomized, 383 completed both the baseline and post-surveys (171 intervention and 212 control). HT initiation among study participants was significantly higher than in the reference population of women (9.3% vs. 4.4%, p < 0.001). There was no difference in HT initiation between the intervention (9.1%) and control groups (9.6%) ( p = 0.83). Initiation rates were 3.8% and 4.5%, respectively ( p = 0.64) for nonhormone therapies. Conclusions Among women with bothersome menopause symptoms, those who underwent previsit symptom screening and received educational materials had higher rates of HT initiation than women who did not participate in the study. These findings suggest that structured menopause education may improve recognition and management of menopause symptoms in routine clinical practice.

Objective Systemic sclerosis (SSc) is an autoimmune disease marked by immune dysregulation, leading to progressive fibrosis and multiorgan dysfunction. Autologous hematopoietic cell transplantation (autoHCT) has demonstrated superiority over conventional immunosuppression in randomized trials yet remains underused in the United States. We report outcomes following implementation of autoHCT as a standard‐of‐care strategy at our institution. Methods We performed a retrospective analysis of consecutive patients with severe SSc undergoing autoHCT between April 1, 2020, and December 31, 2023. Eligibility required progressive disease despite standard immunosuppressive therapy. Primary endpoints were overall survival (OS) and event free survival (EFS). Secondary endpoints included cumulative incidence of relapse and nonrelapse mortality (NRM), organ‐specific outcomes, and transplant‐related complications. Results Twenty‐five patients underwent autoHCT. Median age was 46 years; 80% were female. At a median follow‐up of 23 (interquartile range 16.4–31.9) months, two‐year OS was 91.67% (95% confidence interval [CI] 81.25–100.0) and EFS was 74.51% (95% CI 58.78–94.45). Two‐year cumulative incidence of relapse was 23.93% (95% CI 4.27 –43.59), and NRM was 8.33% (95% CI 2.97–19.64). Significant improvement in Modified Rodnan Skin Score was observed at day +90 and +180 ( P < 0.05), whereas pulmonary function stabilized. Infectious complications occurred in 56% of patients, primarily viral reactivations. Conclusion Implementation of autoHCT for severe SSc in a multidisciplinary care model was associated with favorable survival and meaningful improvement in skin disease, with acceptable toxicity. Earlier referral and optimization of conditioning strategies may further reduce relapse and treatment‐related morbidity.

OBJECTIVE To examine kidney disease outcomes associated with dipeptidyl peptidase 4 inhibitors (DPP-4i). RESEARCH DESIGN AND METHODS In this target trial emulation, claims data from enrollees in commercial, Medicare Advantage, and traditional Medicare health plans were used to identify adults ≥21 years old with type 2 diabetes, with moderate cardiovascular risk, and without stage 3 or worse chronic kidney disease (CKD) initiating alogliptin, linagliptin, saxagliptin, or sitagliptin between 2014 and 2021. The primary outcome was a composite of incident CKD stages 3–5, kidney failure, or kidney replacement therapy. Random treatment assignment was emulated using propensity scores, estimated using the super learner ensemble method and incorporated as inverse probability of treatment weights into proportional hazards models. RESULTS The weighted study cohort included 3,026 individuals starting alogliptin, 38,213 starting linagliptin, 14,934 starting saxagliptin, and 115,091 starting sitagliptin. One year after treatment initiation, the primary outcome occurred in 1.4%, 2.7%, 2.2%, and 2.4% of patients initiating alogliptin, linagliptin, saxagliptin, and sitagliptin, respectively, increasing to 3.2%, 6.2%, 5.0%, and 5.4%, respectively, at 3 years. Alogliptin was associated with lower risk of stage 3 or worse CKD than linagliptin (hazard ratio [HR] 0.50; 95% CI 0.37–0.69), saxagliptin (HR 0.63; 95% CI 0.45–0.86), and sitagliptin (HR 0.58; 95% CI 0.42–0.79), while saxagliptin was associated with lower risk than linagliptin (HR 0.80; 95% CI 0.73–0.87). Conversely, linagliptin was associated with higher risk than sitagliptin (HR 1.15, 95% CI 1.10–1.21). CONCLUSIONS Alogliptin was associated with lower risk of moderate-to-severe kidney disease than other DPP-4i, while linagliptin was associated with higher risk. Limitations include lack of laboratory data and potential unmeasured confounding.

Introduction To assess the within-class variation in kidney outcomes following initiation of sulfonylurea therapy. Research design and methods We used claims data of enrollees in commercial, Medicare Advantage, and traditional Medicare health plans between 2014 and 2021 to emulate a target trial including adults ≥21 years with type 2 diabetes at moderate cardiovascular risk to compare initiation of glimepiride, glipizide, or glyburide on the incidence of chronic kidney disease (CKD) stage 3 or worse, including initiation of kidney replacement therapy (primary outcome); secondary outcomes examined incident CKD stages 3-4, kidney failure (including kidney replacement therapy), all-cause mortality, and hypoglycemia requiring emergency department or hospital care. Random treatment assignment was emulated using propensity scores, estimated using the super learner ensemble method, and incorporated as inverse probability of treatment weights into proportional hazards models. Results The weighted study cohort included 295 092 individuals starting glimepiride (n=134 926), glipizide (n=145 984), and glyburide (n=14 182). One year after treatment initiation, stage 3 or worse CKD developed in 2.1% of patients in the glimepiride group, 2.2% in the glipizide group, and 1.8% in the glyburide group. Glyburide was associated with a lower risk of kidney complications compared with both glimepiride (HR 0.84, 95% CI 0.76 to 0.92) and glipizide (HR 0.81, 95% CI 0.73 to 0.89), despite a higher risk of severe hypoglycemia (HR 1.47, 95% CI 1.27 to 1.71 vs glipizide and HR 1.22, 95% CI 1.05 to 1.42 vs glimepiride). In contrast, the risk of kidney complications was modestly increased with glipizide compared with glimepiride use (HR 1.04, 95% CI 1.00 to 1.07). Conclusions Glyburide was associated with a modestly lower risk of kidney complications, despite a higher risk of hypoglycemia, while glipizide was associated with a higher risk of kidney complications. These hypothesis-generating findings suggest important within-class differences that warrant consideration in clinical decision-making and future research. Despite rigorous prespecified causal inference analytic methods, the risk of unmeasured confounding and bias by indication with the use of observational data remains.

Background SGLT2 (sodium‐glucose cotransporter 2) inhibitors reduce major adverse cardiovascular events (MACE) in type 2 diabetes. However, no direct comparison of individual SGLT2 inhibitor drugs has been conducted, particularly among adults with moderate cardiovascular risk who comprise most people with type 2 diabetes. Methods We used data for commercial, Medicare Advantage, and Medicare fee‐for‐service beneficiaries to emulate a target trial of adults (≥21 years) with type 2 diabetes and moderate cardiovascular risk who started canagliflozin, dapagliflozin, or empagliflozin between 2015 and 2020. We estimated propensity scores using the super learner ensemble method and incorporated them as inverse probability of treatment weights into Cox models, estimating risk of MACE, expanded MACE, and hyperglycemic and hypoglycemic crises through December 31, 2022. Results The weighted cohort, balanced on all baseline covariates, included 137 232 patients (mean age 65.7 years [SD, 8.1], 75.3% non‐Hispanic White, 57.0% male, 81.9% on metformin, 11.4% on glucagon‐like peptide‐1 receptor agonists) starting canagliflozin (N=42 877), dapagliflozin (N=17 871), or empagliflozin (N=7648). The risk of MACE was lower among patients starting empagliflozin versus canagliflozin (hazard ratio [HR], 0.92 [95% CI, 0.87–0.97]), driven by reduced risk of all‐cause mortality (HR, 0.86 [95% CI, 0.80–0.94]). There was no difference in MACE between empagliflozin versus dapagliflozin or dapagliflozin versus canagliflozin therapy. There was no difference in remaining outcomes between the three drugs. Conclusions The 3 most used SGLT2 inhibitor medications demonstrate similar effectiveness on cardiovascular outcomes among patients with type 2 diabetes at moderate cardiovascular risk, with differences between these drugs small in magnitude. Clinicians and health systems should prioritize enhancing access to these cardioprotective therapies.

Introduction To examine within-class sulfonylurea safety, we compared risks of major adverse cardiovascular events (MACE) and severe hypoglycemia among adults with type 2 diabetes (T2D) and moderate cardiovascular risk following sulfonylurea initiation. Research design and methods We conducted a target trial emulation including adults ≥21 years old with T2D and moderate cardiovascular risk who initiated glimepiride, glipizide or glyburide between 2014 and 2021, using claims data from Optum Labs Data Warehouse and the Medicare fee-for-service 100% sample. Study outcomes were MACE (primary), expanded MACE and its components and emergency department or hospital encounters for hypoglycemia, ascertained during follow-up through 2022. Inverse probability of treatment weighting (IPTW) was applied using propensity scores estimated using the super learner ensemble, and outcomes were examined using IPTW Cox proportional hazards models. Results The weighted study cohort comprised 314 699 patients (mean age 66.9 years, 52.0% men, 76.6% non-Hispanic white). At 1 year, MACE was experienced by 2.5%, 2.7% and 2.8% of patients starting glimepiride, glipizide and glyburide, respectively. Compared with glimepiride, glyburide and glipizide were associated with higher risk of MACE (HR 1.10, 95% CI 1.05 to 1.16 for glyburide; HR 1.05, 95% CI 1.03 to 1.07 for glipizide). At 1 year, severe hypoglycemia was experienced by 0.3%, 0.3% and 0.4% of patients starting glimepiride, glipizide and glyburide, respectively. Glyburide was associated with a greater risk of severe hypoglycemia compared with glipizide (HR 1.43, 95% CI 1.23 to 1.65), while glipizide was associated with a lower risk compared with glimepiride (HR 0.82, 95% CI 0.77 to 0.87). Conclusions Among adults with T2D and moderate cardiovascular risk, glimepiride was associated with lowest risk of MACE and glipizide with lowest risk of severe hypoglycemia. These results can help inform treatment selection if sulfonylureas are used for glucose-lowering.

Background Glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) and sodium–glucose cotransporter‐2 inhibitors (SGLT2is) have favorable cardiovascular outcomes compared with dipeptidyl peptidase‐4 inhibitors (DPP4is) and sulfonylureas in adults with type 2 diabetes and high cardiovascular risk. How these benefits vary across lower levels of cardiovascular risk is unknown. Methods We used nationwide claims data to emulate a comparative effectiveness trial and examine the heterogeneity of treatment effects of GLP‐1RAs, SGLT2is, DPP4is, and sulfonylureas on major adverse cardiovascular events (MACEs) among adults with type 2 diabetes and moderate cardiovascular risk (annualized MACE risk 1%–5%, estimated using the annualized claims‐based MACE estimator). Results Among 386 276 included adults with type 2 diabetes, 25.2% had baseline ACME–predicted MACE risk >1% to ≤2% (lower‐risk patients) and 13.3% had ACME–predicted risk >4% to ≤5% (higher‐risk patients). By year 3 of treatment, higher‐risk patients derived greater absolute benefit than lower‐risk patients when treated with GLP‐1RAs versus sulfonylureas (absolute reduction in the estimated rate of MACE of 3.1% in higher‐risk patients and 1.6% in lower‐risk patients), SGLT2is versus sulfonylureas (absolute reduction, 3.9% in higher‐risk patients and 1.3% in lower‐risk patients), and GLP‐1RAs versus DPP4is (absolute reduction, 1.6% in higher‐risk patients and 0.5% in lower‐risk patients). The relative benefits for MACE were also greater in higher‐risk than lower‐risk patients with SGLT2is versus DPP4is (hazard ratio [HR], 0.78 [95% CI, 0.70–0.87] in higher‐risk patients; HR, 0.99 [95% CI, 0.88–1.12] in lower‐risk patients). Conversely, the relative benefits of DPP4is and GLP‐1RAs versus sulfonylureas were greater in lower‐risk patients: HR 0.76 (95% CI, 0.71–0.81) in lower‐risk and HR 0.91 (95% CI, 0.97–0.96) in higher‐risk patients for DPP4is versus sulfonylureas; HR 0.67 (95% CI, 0.58–0.78) in lower‐risk and HR 0.80 (95% CI, 0.70–0.93) in higher‐risk patients for GLP‐1RAs versus sulfonylurea. Benefits of SGLT2is and GLP‐1RAs were comparable across all risk levels. Conclusions Cardiovascular benefits of SGLT2is and GLP‐1RAs exist across all levels of moderate cardiovascular risk, reinforcing the importance of choosing glucose‐lowering therapies that can prevent MACE in all people with type 2 diabetes.

Importance The increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RA) demands a better understanding of their association with thyroid cancer. Objective To estimate the risk of incident thyroid cancer among adults with type 2 diabetes being treated with GLP-1RA vs other common glucose-lowering medications. Design, Setting, and Participants This was a prespecified secondary analysis of a target trial emulation of a comparative effectiveness study using claims data for enrollees in commercial, Medicare Advantage, and Medicare fee-for-service plans across the US. Eligible participants were adults with type 2 diabetes at moderate risk for cardiovascular disease and without history of thyroid cancer who had newly filled prescriptions for GLP-1RA, sodium-glucose cotransporter 2 inhibitor (SGLT2i), dipeptidyl peptidase-4 inhibitor (DPP4i), or sulfonylurea from January 1, 2014, to December 31, 2021. Data were analyzed February 1 to October 31, 2024. Main Outcomes and Measures Overall and piecewise (&amp;lt;1, 1-2, and ≥2 years since treatment initiation) hazard ratios (HRs) for thyroid cancer with use of GLP-1RA vs the other 3 drug classes were estimated using inverse propensity score weighted Cox proportional hazards models. Modified intention-to-treat (mITT) (primary) and as-treated (sensitivity) analyses were performed. Results Of 351 913 patients (mean [SD] age, 65.3 [8.5] years; 173 391 [49.3%] females and 178 522 [50.7%] males), 41 112 started treatment with GLP-1RA; 76 093, with DPP4i; 43 499, with SGLT2i; and 191 209, with sulfonylurea therapy. The numbers of patients diagnosed with thyroid cancer were 69 (0.17%) in the GLP-1RA group, 172 (0.23%) in the DPP4i group, 72 (0.17%) in the SGLT2i group, and 381 (0.20%) in the sulfonylurea group. In the mITT analysis, GLP-1RA initiation was not significantly associated with increased overall risk for thyroid cancer compared to the other 3 diabetes drugs (HR, 1.24; 95% CI, 0.88-1.76). However, the risk for thyroid cancer was significantly higher within the first year after GLP-1RA initiation (HR, 1.85; 95% CI, 1.11-3.08) and was amplified in the overall as-treated analysis that censored patients when therapy was discontinued or another medication was added (HR, 2.07; 95% CI, 1.10-3.95). Conclusions and Relevance This secondary analysis of a target trial emulation of a comparative effectiveness study found that despite the low absolute risk of thyroid cancer among patients receiving GLP-1RA therapy, there was an increased risk of new thyroid cancer diagnoses within the first year of GLP-1RA initiation compared to 3 other diabetes drugs. This finding may have been due to enhanced early detection; therefore, further research is necessary to understand the underlying causes of this association.

Key Points Sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists were superior to dipeptidyl peptidase-4 inhibitor and sulfonylurea for preventing kidney complications in patients with type 2 diabetes at moderate cardiovascular disease risk. Sodium-glucose cotransporter 2 inhibitor therapy compared favorably with glucagon-like peptide-1 receptor agonists for kidney disease outcomes. Background CKD is a serious diabetes-related complication. While guidelines recommend use of sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies to mitigate cardiorenal risk in high-risk patients, the benefit of early initiation of these agents relative to other commonly prescribed glucose-lowering agents in patients at lower baseline cardiovascular disease (CVD) risk remains less clear. Methods This retrospective observational study emulated an idealized target trial using claims data from OptumLabs data warehouse to test the comparative association of treatment with a dipeptidyl peptidase-4 inhibitor (DPP-4i), SGLT2i, GLP-1RA, or sulfonylurea (SU) on a primary kidney composite outcome of incident CKD stages 3–5, kidney failure, or need for KRT in patients with type 2 diabetes and moderate CVD risk. A secondary composite outcome included all components of the primary composite outcome plus death. Results A total of 364,714 adults aged 21 years or older initiating treatment with a DPP-4i ( N =78,843), GLP-1RA ( N =42,049), SGLT2i ( N =45,466), or SU ( N =198,356) were identified. Relative to DPP-4i, SGLT2i (hazard ratio [HR], 0.71; 95% confidence interval [CI], 0.67 to 0.74; P < 0.001) and GLP-1RA (HR, 0.87; 95% CI, 0.83 to 0.92; P < 0.001) treatment was superior for the primary composite outcome. Similarly, SGLT2i (HR, 0.69; 95% CI, 0.66 to 0.73) and GLP-1RA (HR, 0.86; 95% CI, 0.82 to 0.91) treatment was associated with risk reductions for the primary outcome relative to SU treatment. When comparing SGLT2i with GLP-1RA therapy, SGLT2is were superior for the primary composite outcome (HR, 0.81; 95% CI, 0.75 to 0.86; P < 0.001). Similar findings were observed for the secondary composite outcome across all comparisons. Conclusions SGLT2is and GLP-1RAs were superior to DPP-4is and SUs for preventing kidney complications in a type 2 diabetes population with moderate baseline CVD risk.
