Non-stenotic carotid disease is not only common, but also associated with substantial risk after

Non-Stenotic Carotid Disease is Common, Substantially Increases Risk After Ischemic Stroke

 in Seoul, South Korea, by Amy Yu, MD, MSc, associate professor of neurology at the University of Toronto and senior scientist at the Sunnybrook Research Institute, these data challenge the traditional understanding of “clinically insignificant” stenosis.

“Carotid disease accounts for about 10% of all ischemic stroke, and we know that people with severe carotid stenosis should be treated with interventions for revascularization,” Yu told 

 in an exclusive interview. “The <50% carotid disease, the non-stenotic category, is really a mixed bag, and we’re now recognizing that some of these patients can go on to have high-risk stroke events or other kinds of major adverse cardiovascular events.”

Despite the clinical significance of non-stenotic carotid disease, it remains a relatively understudied pathology in stroke. Prior studies have identified imaging features of high-risk non-stenotic plaques, but as of July 2026, there is still no standardized definition of symptomatic non-stenotic carotid disease.

To address this, Yu and colleagues conducted a population-based study in Ontario using the Ontario Stroke Registry, specifically sourcing data from 2019-2023. Patients who were hospitalized with ischemic stroke within 24 hours of onset and who had a documented carotid stenosis severity of <50% or ≥50% were enrolled in the study and categorized by the highest degree per patient. The team compared outcomes such as in-hospital mortality and major adverse cardiovascular events (MACE) until 2025 by stenosis severity, utilizing modified Poisson and Cox regression models adjusted for demographics, stroke severity, and comorbidities.

A total of 15,796 patients were included in the study, among whom 78.5% had non-stenotic carotid disease (defined as stenosis severity <50%). Patients with <50% stenosis also had lower burdens of 

 risk factors like hypertension (81.7% vs 87.5%), diabetes (37.4% vs 43.7%), prior stroke (11.4% vs 14.7%), coronary artery disease (13.3% vs 22%), and smoking (13.5% vs 18.8%).

However, despite these differences, Yu and colleagues noted that event rates for ischemic stroke (9.4% vs 9.5%; adjusted HR, 0.96; 95% CI, 0.84-1.11) and myocardial infarction (2% vs 3.2%; aHR, 0.76; 95% CI, 0.59-1) were similar in both groups. In-hospital mortality also remained substantial across both populations, although it was numerically lower in those with ≥50% stenosis (adjusted risk ratio [RR], 0.77; 95% CI, 0.7-0.86). Long-term mortality risk was only modestly lower in patients with <50% stenosis (aHR, 0.83; 95% CI, 0.77-0.89).

Ultimately, Yu and colleagues concluded that these data, while relatively early and hypothesis-generating, still display the significant risk posed by non-stenotic carotid disease. Mortality and MACE risk in patients with <50% stenosis approached those seen in ≥50% stenosis, highlighting an underrepresented risk. The team determined that this population needs improved risk stratification and optimized disease management strategies.

“If we’re able to quantify long-term risks on a population basis, it’s really helpful for other people who want to plan future clinical trials or cohort studies to be able to know the outcome numbers that we’re looking at, and the sample size calculations, and so on,” Yu said. “I’m hoping that this study can provide a bit of background information and be hypothesis-generating for future studies as well.”

 (CIndU) has long lacked approved therapies, leaving clinicians to rely on up-dosed antihistamines and off-label agents for a frequently persistent disease.

In this HCPLive Special Report, Andrea Nguyen, DMSc, MPAS, PA-C, of First OC Dermatology, spoke with Adam Friedman, MD, of George Washington University School of Medicine and Health Sciences, about how the approval of remibrutinib (Rhapsido),  an oral Bruton tyrosine kinase (BTK) inhibitor, for adults with symptomatic dermographism inadequately controlled by H1 antihistamines.

Experts discuss remibrutinib, the first FDA-approved therapy for symptomatic dermographism, and its role in chronic inducible urticaria.

Special Report: Remibrutinib, an Oral BTKi, for Chronic Inducible Urticaria

In the phase 3 RemIND trial, 115 adults with a mean disease duration of 5.8 years received remibrutinib 25 mg or placebo twice daily. At week 12, 29.3% (17/58) vs 14.0% (8/57) achieved a complete response on the Total Fric Score (P = .0229). Responses emerged by week 2, persisted through week 24, and held regardless of baseline total IgE.

A complete response means no wheal after standardized friction provocation, a stringent bar in easily provoked skin. This consistency across IgE levels supports broad applicability, unlike CSU, where IgE can predict response to omalizumab (Xolair).

Remibrutinib blocks BTK downstream of high-affinity IgE receptor cross-linking, halting mast cell degranulation whether activation is IgE- or IgG-mediated. Its efficacy in dermographism also suggests a BTK role in inducible mast cell activation.

Safety mirrored the REMIX trials in CSU, where petechiae occurred more often with remibrutinib than placebo (3.8% vs 0.3%).

 Mild mucocutaneous bleeding reflects BTK's role in platelet function, and no routine laboratory monitoring is required.

Collectively, the approval gives clinicians evidence-based footing in a long-neglected condition. Data from cold and cholinergic urticaria cohorts may extend the reach of BTK inhibition further.

Improving Diagnostic Evaluation in EoE

In this episode, ‘Improving Diagnostic Evaluation in EoE,’ the panelists explore how clinicians can recognize patients who warrant evaluation for eosinophilic esophagitis and improve the quality of the diagnostic workup. The experts emphasize that dysphagia and food impaction should clearly prompt further investigation, but adaptive eating behaviors may provide subtler clues. Patients may avoid problematic foods or normalize abnormal swallowing patterns because similar behaviors have developed gradually or are shared by family members.

The discussion then focuses on endoscopic evaluation. The panel explains that clinicians should assess for inflammatory findings such as edema, furrows, and exudates, as well as rings, strictures, reflux-related changes, and other potential causes of dysphagia. Importantly, a normal-appearing esophagus does not exclude EoE. Faculty stress that biopsies remain essential because disease can be patchy and visually subtle. They discuss obtaining multiple biopsies from different levels of the esophagus and using standardized EREFS documentation to objectively track endoscopic findings over time.

The experts also identify food impaction as an important diagnostic opportunity that is too often missed, particularly during urgent procedures. Failure to obtain biopsies may lead to patients being lost to follow-up once the acute obstruction is relieved. The panel highlights practical strategies for improving biopsy rates and emphasizes that systematic evaluation can shorten the interval between symptoms and diagnosis.

The next episode in this series, ‘Recognizing Progression and Fibrostenotic Disease in EoE,’ features the panelists discussing demographic misconceptions, diagnostic delay, and the

relationship between persistent inflammation and fibrostenotic progression.

Early EoE recognition depends on looking beyond overt dysphagia and performing an adequate diagnostic evaluation. Careful endoscopy and appropriately distributed biopsies can prevent missed opportunities for diagnosis.

Understanding Epithelial Dysfunction and Symptom Adaptation in EoE

Welcome back to another HCP Live Peer Exchange series. In this episode titled, ‘Understanding Epithelial Dysfunction and Symptom Adaptation in EoE,’ the panel of experts examines the evolving understanding of eosinophilic esophagitis pathophysiology and the factors that contribute to delayed recognition of disease. The faculty discuss the esophageal epithelium as an active component of immune function rather than simply a passive barrier, emphasizing the bidirectional relationship between epithelial injury and type 2 inflammation. They explain how this broader understanding has shifted attention beyond the eosinophil toward upstream inflammatory pathways and other potential therapeutic targets.

The panel then explores why EoE care frequently remains symptom-driven despite the underlying chronic disease process. Faculty highlight barriers to specialty care and the challenge of relying on patients to recognize and report symptoms that may have developed gradually. They emphasize that patients often normalize dysphagia and develop compensatory eating behaviors, including drinking excessive fluids with meals, avoiding certain foods, chewing extensively, or taking longer to eat. Family members may recognize these changes before patients themselves appreciate their significance. The experts stress the importance of asking detailed questions about eating patterns and adaptive behaviors to uncover disease burden that may otherwise remain hidden.

In the next episode, ‘Improving Diagnostic Evaluation in EoE,’ panelists will continue their discussion on EoE and highlight clinical presentations that should prompt evaluation, along with best practices for endoscopy and esophageal biopsy.

EoE extends beyond eosinophilic inflammation, with epithelial barrier dysfunction helping perpetuate disease activity. Recognizing how patients adapt to chronic symptoms may be equally important for identifying disease earlier.

 who reached clinical remission with twice-yearly depemokimab (Exdensur) in year 1 had fewer exacerbations and greater lung function gains in year 2, according to an integrated analysis presented at the 

Depemokimab, an ultra-long-acting interleukin-5 (IL-5) antagonist, received FDA approval in December 2025 as add-on maintenance treatment for severe asthma with an eosinophilic phenotype in patients aged 12 years and older.² In the 52-week phase 3 SWIFT-1/-2 trials, 29% of patients receiving depemokimab achieved 4-component clinical remission at week 52, compared with 23% of patients receiving placebo.¹ The new analysis asked whether remission status at the end of year 1 carried forward into a second year of continuous treatment.

“If you can achieve remission with a specific therapy, you’re more likely to continue to stay in remission,” said Michael E. Wechsler, MD, MMSc, professor of medicine and director of The Cohen Family Asthma Institute at National Jewish Health. “It gives [us] confidence that the therapy is working and that patients will continue to do well with that therapy.”

Depemokimab Year 1 Remission Linked to Better Year 2 Asthma Outcomes

Depemokimab Clinical Remission Durability in SWIFT and AGILE

The integrated post hoc analysis included patients who received depemokimab across both the SWIFT-1/-2 trials and the 52-week AGILE open-label extension study.¹ Investigators defined 4-component clinical remission as no exacerbations across 52 weeks, no maintenance oral corticosteroid use in the final 90 days, an Asthma Control Questionnaire (ACQ)-5 score < 1.5, and a change from baseline in forced expiratory volume in 1 second (FEV1) of ≥ 0 mL.¹

Of 419 patients treated with depemokimab in both years, 405 entered the clinical remission analysis set.¹ A total of 30% (123/405) achieved clinical remission at the end of year 1, and 59% (73/123) of these patients maintained remission at the end of year 2.¹ The remaining 70% did not reach remission in year 1.¹

During year 2, the annualized exacerbation rate was 0.19 (95% CI, 0.12–0.29) among patients in remission at year 1, compared with 0.69 (95% CI, 0.57–0.82) among patients not in remission.¹ Wechsler noted patients who sustained remission into year 2 had no exacerbations, stable or improved lung function, no significant symptoms, and no steroid use for asthma.

Depemokimab Year 2 Outcomes in FEV1, ACQ-5, and SGRQ Scores


Depemokimab (Exdensur) is FDA approved as add-on maintenance treatment for severe asthma with an eosinophilic phenotype in patients aged 12 years and older, dosed by subcutaneous injection twice yearly.²


Depemokimab is an ultra-long-acting monoclonal antibody with enhanced IL-5 binding affinity and an extended half-life, which reduces eosinophilic inflammation and allows dosing every 6 months.¹

What did the SWIFT/AGILE remission analysis show?


Of patients in clinical remission at the end of year 1, 59% remained in remission at year 2, with a year 2 annualized exacerbation rate of 0.19 vs 0.69 in patients not in remission.¹

Patients achieving remission at the end of year 1 showed greater improvements across all 3 secondary outcomes at the end of year 2, measured as least squares mean change from SWIFT-1/-2 baseline.¹ St George’s Respiratory Questionnaire (SGRQ) total score improved by −23.57 points (95% CI, −26.53 to −20.62) in the remission group vs −13.15 points (95% CI, −15.13 to −11.17) in the nonremission group.¹

ACQ-5 score changed by −1.34 (95% CI, −1.51 to −1.17) in patients with year 1 remission vs −0.71 (95% CI, −0.82 to −0.60) in patients without remission.¹ Pre-bronchodilator FEV1 improved by 379 mL (95% CI, 301–458) vs 85 mL (95% CI, 33–137), respectively.¹ The trend remained consistent at every assessed timepoint during year 2.¹

Wechsler emphasized the 70% of patients not meeting the 4-component definition in year 1 may still benefit from continued treatment. He described remission as a high bar and noted ongoing debate among experts on which components and what duration should define it.

“Not everyone’s going to achieve remission, but they might still have benefits,” Wechsler said. “They might have benefits in terms of reduction in steroid dose, reduction in exacerbations, improvement in lung function, [and] improvement in symptoms.”

He added a 3-component definition without a lung function criterion may better fit patients with a near-normal baseline FEV1, for whom eliminating prior exacerbations is the more meaningful outcome.

“Sometimes some people start off [with] a high lung function,” he said. “If their FEV1 is 85%, they may not necessarily improve in terms of lung function. Whereas if they had two exacerbations in the year prior, that is important.”
