Background & Aims: We examined treatment patterns and clinical outcomes in a contemporary cohort of children with newly diagnosed inflammatory bowel disease (IBD) in a large, commercially insured U.S. population. Methods: Using the OptumLabs® Data Warehouse, we created an inception cohort of physician-diagnosed IBD in children aged 6–17 years between 2007–23. We examined cumulative incidence of hospitalization, surgery, safety events, and medication use in patients with Crohn's disease (CD) and ulcerative colitis (UC), overall and stratified by diagnostic era, race and ethnicity, sex, and age at diagnosis. Results: Among 787 children with newly diagnosed CD (age at diagnosis, 13.4±2.9y; 57% male; 82% White, 5% Black, 7% Hispanic) followed over mean 4.6±3.0y, 5-year risk of IBD-related hospitalization and major surgery was 30% and 10%, respectively. In children diagnosed in 2019–23, 1-year cumulative use of corticosteroids and advanced therapy was 46% and 75%, respectively; advanced therapy use increased significantly over time (aHR, 3.43 [95% CI, 2.71–4.32] for 2019–23 vs. 2007–12), while corticosteroid use declined (0.67 [0.53–0.84]). Risk of IBD-related hospitalization was lower in children diagnosed between 2019–23 (0.65 [0.43–0.97]) compared with those diagnosed between 2007-12; surgical risk did not decline significantly, with confidence intervals compatible with a clinically meaningful reduction. Among 399 children with newly diagnosed UC (age at diagnosis, 14.0±3.0y; 53% male; 78% White, 5% Black, 7% Hispanic) followed over 4.5±3.0y, 5-year risk of IBD-related hospitalization and colectomy was 36% and 8%, respectively. Advanced therapy use increased significantly over time (4.46 [2.85–6.98] for 2019–23 vs. 2007–12), with no significant change in hospitalization or surgical risk across eras. No consistent racial and ethnic, age, or sex differences in advanced therapy use or clinical outcomes were identified in either CD or UC. Conclusions: In a contemporary cohort of commercially insured children with newly diagnosed IBD, early advanced therapy use has increased markedly over time. Surgical risk did not decline significantly in either disease; however, the study was not powered to exclude a clinically meaningful reduction, and these findings are hypothesis-generating rather than conclusive.

Abstract Introduction Despite regulatory mandates for advanced therapy (AT) washout periods of up to 5 drug half-lives before enrolling patients in inflammatory bowel disease (IBD) trials, the evidence base for these requirements is largely empirical, and whether shorter intervals independently increase the risk of serious infections in real-world practice remains unknown. Methods Using the OptumLabs Data Warehouse, we identified adult patients with IBD who initiated a new AT (tumor necrosis factor antagonists, vedolizumab, interleukin (IL)-12/23 or IL-23 antagonists, or Janus kinase inhibitors) between 2018 and 2023 using a class-specific new-user design. We examined whether exposure to AT within the preceding 12 months (vs no exposure to AT within that window) and timing of discontinuation (≤1 month, 1-<3 months, or 3-12 months) were associated with risk of serious infections using multivariable Cox proportional hazards regression. Results Among 21 564 AT initiators (47 ± 18 years; 52% female; 57% Crohn’s disease), 7490 (34.7%) had AT exposure within the preceding 12 months. Over a mean follow-up of 1.6 ± 0.9 y, 1955 (9.1%) experienced a serious infection. Prior AT exposure was associated with higher infection risk (hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 1.07-1.33), consistent in inverse probability of treatment-weighted analyses (HR, 1.20 [1.06-1.37]). Among patients with prior exposure, timing of discontinuation was not associated with infection risk (HR, 1.17 [0.95-1.43] for ≤1 month vs 3-12 months; HR, 1.01 [0.83-1.22] for 1-<3 months), with no dose–response relationship on continuous modeling. Discussion AT exposure within the preceding 12 months is associated with modestly higher risk of serious infection after initiating a new AT in IBD, but timing of discontinuation does not independently influence this risk.

Importance With the availability of multiple classes of advanced therapies for the treatment of Crohn disease (CD), understanding the comparative safety of different therapies can inform treatment positioning. Objective To compare the risk of serious infections, venous thromboembolism (VTE), and major adverse cardiovascular events (MACE) with different advanced therapies in patients with CD. Design, Setting, and Participants This retrospective comparative effectiveness research study was conducted between January 1, 2016, and December 31, 2022, with a mean (SD) follow-up of 26.9 (2.4) months until July 1, 2024. Using an administrative claims database (OptumLabs Data Warehouse), commercially insured patients with CD, who initiated treatment with tumor necrosis factor-α (TNF) antagonists, anti-integrin agents (vedolizumab), interleukin (IL)-12/23p40 antagonists (ustekinumab), IL-23p19 antagonists (primarily risankizumab), or Janus kinase inhibitors (upadacitinib) between 2016 and 2022 and had follow-up for at least 1 year before and after treatment initiation, were included. Exposure TNF antagonists vs anti-integrin agents (vedolizumab) vs IL-12/23p40 antagonists (ustekinumab) vs IL-23p19 antagonists (risankizumab) vs Janus kinase inhibitors (upadacitinib). Main Outcomes and Measures The risk of serious infections, VTE, and MACE was compared with various advanced therapies through multinomial propensity score-based inverse probability treatment weighting, with propensity scores estimated through generalized boosted models, accounting for disease characteristics, health care utilization, comorbidities, and prior and concomitant medications, and through competing risk of mortality. Cause-specific hazard ratios (HRs) and 95% CIs for multiple treatment comparisons were calculated. Results This study included 12 245 patients with CD (mean [SD] age, 46.5 [17.5] years; 6642 females [54.2%]), who were treated with TNF antagonists (n = 5274), vedolizumab (n = 2716), ustekinumab (n = 3544), risankizumab (n = 559), or upadacitinib (n = 152). Serious infection incidence rates ranged from 5.46 (95% CI, 4.86-6.07) to 9.02 (95% CI, 6.38-11.89) per 100 person-years across therapies. After adjusting for confounding variables, there were no statistically significant differences in the risk of serious infections across different agents, including between risankizumab and ustekinumab (HR, 1.14 [95% CI, 0.78-1.67]), risankizumab and TNF antagonists (HR, 1.00 [95% CI, 0.68-1.47]), or ustekinumab and TNF antagonists (HR, 0.88 [95% CI, 0.74-1.04]). The incidence of VTE (incidence rate, 0.90 [95% CI, 0.71-1.10] to 2.33 [95% CI, 1.06-3.82] per 100 person-years) and MACE (0.68 [95% CI, 0.51-0.85] to 1.49 [95% CI, 0.43-2.76] per 100 person-years) was low, without any significant differences across agents. Conclusions and Relevance In this comparative effectiveness research study of patients with CD, no significant differences in the risks of serious infections, VTE, or MACE across various advanced therapies were found. These findings support clinical decision-making on choice of advanced therapies for most individual patients with CD to be driven primarily by comparative treatment effectiveness rather than driven by concerns of serious adverse events.

ABSTRACT We conducted a USA claims‐based cohort study in 20,705 patients with inflammatory bowel diseases (IBD) on advanced therapies to estimate the overall and comparative risk of tuberculosis between advanced therapies using inverse probability of treatment weighted Cox proportional hazards model. The incidence rate (IR, per 100,000 person‐years) of tuberculosis with TNF antagonists ( n = 9378) and non‐TNF‐targeting biologics (anti‐integrins [ n = 5877], anti‐interleukins [ n = 5450]) was similar (38 [95% CI, 8–69] vs. 33[7–59]). Adjusting for covariates, risk of tuberculosis was similar (HR, 1.16 [0.41–3.31]). In low incidence regions like USA, the incidence of tuberculosis after starting advanced therapies for IBD is very low, and comparable across advanced therapies.

INTRODUCTION: We conducted a retrospective cohort study comparing the safety of advanced therapies in patients with ulcerative colitis (UC). METHODS: Using an administrative claims database (OptumLabs Data Warehouse), we identified patients with UC who initiated treatment with tumor necrosis factor-α (TNF) antagonists, anti-integrin agents, anti-interleukin, Janus kinase inhibitors (JAK), or sphingosine-1 phosphate receptor modulators between 2016 and 2022 and had followed up for at least 1 year before and after treatment initiation. We compared the risk of serious infections, venous thromboembolism, and major adverse cardiovascular events through multinomial propensity score-based inverse probability weighting, with propensity scores estimated through generalized boosted models that accounted for disease characteristics, healthcare utilization, comorbidities, and previous and concomitant medications, and the competing risk of mortality. We calculated cause-specific hazard ratios (HR) and 95% confidence intervals for multiple treatment comparisons. RESULTS: We included 9,430 patients with UC treated with TNF antagonists (n = 4,111), anti-integrins (n = 3,165), anti-ILs (n = 1,342), JAK inhibitors (n = 701), or sphingosine-1 phosphate receptor modulators (n = 111), followed over median 27 months. After adjusting for confounding variables, anti-ILs were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [95% confidence interval, 0.51–0.87]) and anti-integrins (HR, 0.75 [0.57–0.98]). JAK inhibitors were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [0.46–0.94]). The incidence of venous thromboembolism (incidence rate, 1.4–2.0 per 100 py) and major adverse cardiovascular event (0.5–1.0 per 100 py) was very low, without any significant differences across agents. DISCUSSION: In a real-world cohort of patients with UC, anti-ILs and JAK inhibitors were associated with a lower risk of serious infections and may offer net benefit, especially in patients with previous TNF antagonist exposure.

ABSTRACT Background Advanced therapies increase the risk of shingles in inflammatory bowel diseases (IBD). Aim To compare the risk of shingles with different advanced therapies in patients with IBD. Methods We identified patients with IBD who initiated treatment with tumour necrosis factor (TNF) antagonists, anti‐integrins, anti‐interleukins, Janus kinase (JAK) inhibitors, or sphingosine‐1 phosphate receptor (S1PR) modulators between 2016 and 2022 and had follow‐up for at least 1 year before and after treatment initiation. We estimated the incidence rate (IR per 100 person‐year [PY]) of shingles (overall and complicated) and compared the risk with different advanced therapies through multinomial propensity score‐based inverse probability of treatment weighting (IPTW), with propensity scores estimated through generalised boosted models, accounting for disease characteristics, healthcare utilisation, comorbidities and prior and concomitant medications. Weighted Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for multiple treatment comparisons. Results We included 21,675 patients followed over 27 months. IRs per 100 PY of shingles and complicated shingles were: TNF antagonists 1.0/0.3, anti‐integrin agents 1.4/0.4, anti‐interleukins 1.2/0.5, JAK inhibitors 3.3/0.9 and S1PR modulators 2.0/1.0. After adjusting for confounding variables, JAK inhibitors were associated with higher risks of shingles than TNF antagonists (HR 2.19; 1.28–3.75), anti‐integrins (HR 1.87; 1.12–3.14) and anti‐interleukins (HR 1.70; 0.98–2.96). Conclusions JAK inhibitors were associated with 1.7–2.2‐fold higher risk of shingles than other advanced therapies.

Abstract Aims Pericardiocentesis is usually completed under fluoroscopy. The electroanatomic mapping (EAM) system allows visualizing puncture needle tip (NT) while displaying the electrogram recorded from NT, making it possible to obtain epicardial access (EA) independent of fluoroscopy. This study was designed to establish and validate a technique by which EA is obtained under guidance of three-dimensional (3D) EAM combined with NT electrogram. Methods and results 3D shell of the heart was generated, and the NT was made trackable in the EAM system. Unipolar NT electrogram was continuously monitored. Penetration into pericardial sac was determined by an increase in NT potential amplitude and an injury current. A long guidewire of which the tip was also visible in the EAM system was advanced to confirm EA. Epicardial access was successfully obtained without complication in 13 pigs and 22 patients. In the animals, NT potential amplitude was 3.2 ± 1.0 mV when it was located in mediastinum, 5.2 ± 1.6 mV when in contact with fibrous pericardium, and 9.8 ± 2.8 mV after penetrating into pericardial sac (all P ≤ 0.001). In human subjects, it measured 1.54 ± 0.40 mV, 3.61 ± 1.08 mV, and 7.15 ± 2.88 mV, respectively (all P < 0.001). Fluoroscopy time decreased in every 4–5 cases (64 ± 15, 23 ± 17, and 0 s for animals 1–4, 5–8, 9–13, respectively, P = 0.01; 44 ± 23, 31 ± 18, 4±7 s for patients 1–7, 8–14, 15–22, respectively, P < 0.001). In five pigs and seven patients, EA was obtained without X-ray exposure. Conclusion By tracking NT in the 3D EAM system and continuously monitoring the NT electrogram, it is feasible and safe to obtain EA with minimum or no fluoroscopic guidance.

Purpose: Studies have documented that the majority of consent documents for medical diagnosis and treatment are written at a reading level above that of the majority of the U.S. population. This study hypothesized that use of an easy-to-read consent statement, when compared with a standard consent statement, will result in higher patient comprehension of the clinical treatment protocol, lower patient anxiety, higher patient satisfaction, and higher patient accrual.Methods: A randomized controlled trial was conducted in 44 institutions that were members or affiliates of three cooperative oncology groups. Institutions were randomly assigned to administer either an easy-to-read consent statement or the standard consent statement to patients being recruited to participate in selected cancer treatment trials. Telephone interviews were conducted with a total of 207 patients to assess study outcomes.Results: Patients in the intervention arm demonstrated significantly lower consent anxiety and higher satisfaction compared with patients in the control arm. Patient comprehension and state anxiety were not affected by the intervention. Accrual rates into the parent studies also did not differ significantly between the two study groups.Conclusion: Clinical trial informed consent statements can be modified to be easier to read without omitting critical information. Patient anxiety and satisfaction can be affected by the consent document. The generalizability of these study results is limited by the characteristics of the patient sample. Ninety percent of the sample were white women, and the mean Rapid Estimate of Adult Literacy in Medicine score was approximately 64, indicating a literacy level at or above the ninth grade.
