The aim of this analysis was to report the interim 1-year data for patients with AD enrolled in the GLOBOSTAD registry, including treatment patterns, dupilumab effectiveness and safety, and healthcare burden.

Methods: GLOBOSTAD is an ongoing, 5-year, multinational, prospective, observational study of adult/adolescent (aged ≥ 12 years at baseline) patients with AD who initiated dupilumab in real-world settings according to their local country-specific prescribing guidelines.

Effect of Dupilumab on Radiological Remission in Patients with Chronic Rhinosinusitis with Nasal Polyp: A One Step Forward Toward Clinical Remission.

Background And Objectives:  While achieving complete radiological improvement in patients with nasal polyps is often observed following surgical resection, the impact of biologic therapy, specifically dupilumab, on polyp size is an area of great interest. The objective of this study was to assess the effect of dupilumab in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) by assessing nasal polyps using the computed tomography (CT) staging system, Lund-Mackay score (LMS).

Methods:  A two-year prospective cohort study was conducted on 29 patients diagnosed with CRSwNP and asthma and eligible for dupilumab as an add-on therapy.

Real-World Effectiveness of Mepolizumab in Severe Asthma: Results from the Multi-country, Self-controlled Nucala Effectiveness Study (NEST).

Introduction: The Nucala Effectiveness Study (NEST) assessed the effectiveness of mepolizumab in patients with severe asthma (SA) in countries previously underrepresented in real-world studies.

Methods: A multi-country, bi-directional, self-controlled, observational cohort study conducted in Colombia, Chile, India, Türkiye, Saudi Arabia, United Arab Emirates, Kuwait, Oman, and Qatar. Historical and/or prospective data from patients with SA were assessed 12 months pre- and post-mepolizumab initiation.

Real-world biologics response and super-response in the International Severe Asthma Registry cohort.

Background: Biologic asthma therapies reduce exacerbations and long-term oral corticosteroids (LTOCS) use in randomized controlled trials (RCTs); however, there are limited data on outcomes among patients ineligible for RCTs. Hence, we investigated responsiveness to biologics in a real-world population of adults with severe asthma.

Methods: Adults in the International Severe Asthma Registry (ISAR) with ≥24 weeks of follow-up were grouped into those who did, or did not, initiate biologics (anti-IgE, anti-IL5/IL5R, anti-IL4/13).

APPaRENT 3: Asthma Patients' and Physicians' Perspectives on the Burden and Management of Asthma in Seven Countries.

Introduction: Asthma management is strongly dependent on physician and patient beliefs and perceptions about the disease and its long-term treatment. The APPaRENT 3 study was conducted to explore factors influencing treatment choice and to understand patients' and physicians' attitudes and perspectives on the use of controller inhalers in regular versus flexible dosing for asthma management.

Methods: This cross-sectional survey of patients with asthma and treating physicians was conducted in seven countries: Indonesia, Malaysia, Philippines, Thailand, Vietnam (patient survey only), Saudi Arabia, and the United Arab Emirates.

Exploring Clinical Remission in Moderate Asthma - Perspectives from Asia, the Middle East, and South America.

Introduction: Clinical remission is a relatively new concept in asthma but recent research initiatives suggest it could be an ambitious and achievable therapeutic target for patients with asthma.

Methods: In this modified Delphi study (comprising two online surveys, completed either side of a virtual scientific workshop), the opinions of a panel of respiratory physicians were evaluated to summarize perspective statements on key therapeutic outcomes and criteria for on-treatment clinical remission in patients with moderate asthma. An agreement threshold was pre-defined as agreement by ≥ 75% of participants.

Expert consensus on oral corticosteroids stewardship for the treatment of severe asthma in the Middle East and Africa.

In the Middle East and Africa (MEA) region, overuse of oral corticosteroids (OCS) for asthma management, both as burst and maintenance therapy, poses a significant challenge. Gaps in knowledge regarding the need to taper OCS in patients with severe asthma and the use of OCS in comorbid conditions have been noted. OCS stewardship can help attain optimal and effective OCS tapering along with reducing OCS overuse and over-reliance.

Exploring Definitions and Predictors of Response to Biologics for Severe Asthma.

Background: Biologic effectiveness is often assessed as response, a term that eludes consistent definition. Identifying those most likely to respond in real-life has proven challenging.

Objective: To explore definitions of biologic responders in adults with severe asthma and investigate patient characteristics associated with biologic response.

Exploring the immunopathology of type 2 inflammatory airway diseases.

Significant advancements have been achieved in understanding the roles of different immune cells, as well as cytokines and chemokines, in the pathogenesis of eosinophilic airway conditions. This review examines the pathogenesis of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP), marked by complex immune dysregulation, with major contributions from type 2 inflammation and dysfunctional airway epithelium. The presence of eosinophils and the role of T-cell subsets, particularly an imbalance between Treg and Th17 cells, are crucial to the disease's pathogenesis.

Patient-Reported Outcome Measures in Atopic Dermatitis and Chronic Urticaria Are Underused in Clinical Practice.

Background: Patient-reported outcome measures (PROMs) are validated and standardized tools that complement physician evaluations and guide treatment decisions. They are crucial for monitoring atopic dermatitis (AD) and chronic urticaria (CU) in clinical practice, but there are unmet needs and knowledge gaps regarding their use in clinical practice.

Objecctive: We investigated the global real-world use of AD and CU PROMs in allergology and dermatology clinics as well as their associated local and regional networks.

International Variation in Severe Exacerbation Rates in Patients With Severe Asthma.

Background: Exacerbation frequency strongly influences treatment choices in patients with severe asthma.

Research Question: What is the extent of the variability of exacerbation rate across countries and its implications in disease management?

Study Design And Methods: We retrieved data from the International Severe Asthma Registry, an international observational cohort of patients with a clinical diagnosis of severe asthma. We identified patients aged ≥ 18 years who did not initiate any biologics prior to baseline visit.

Impact of pre-biologic impairment on meeting domain-specific biologic responder definitions in patients with severe asthma.

Background: There is little agreement on clinically useful criteria for identifying real-world responders to biologic treatments for asthma.

Objective: To investigate the impact of pre-biologic impairment on meeting domain-specific biologic responder definitions in adults with severe asthma.

Methods: This was a longitudinal, cohort study across 22 countries participating in the International Severe Asthma Registry (https://isaregistries.

Factors influencing poor response to type 2 targeted therapies in severe asthma: a retrospective cohort study.

Background: A significant breakthrough has been made in treating severe asthma, with the recognition of various asthma phenotypes and an updated management guideline. Type 2 targeted therapies, such as benralizumab and omalizumab; have been identified as an effective treatment for severe asthma, improving patient response, lung function tests and asthma symptom control. This study aimed to evaluate factors contributing to poor response to therapy.
