Background: There is increasing recognition of marked phenotypic heterogeneity within severe asthma patients.
Methods: Severe asthma patients on GINA step 4 or 5 treatment, followed up at Al-Rashed Allergy center Kuwait, were evaluated for: demographics (gender, age, age of asthma onset), comorbidities (allergic rhinitis (AR), chronic rhinosinusitis (CRS), chronic rhinosinusitis with nasal polyposis (CRSwNP), obesity), blood biomarkers (total serum Immunoglobulin E (IgE), peripheral eosinophils), and sensitization to inhalants allergens.
Results: A total of 169 patients were candidates for biological treatment.
A worldwide increase in prevalence of allergic diseases has led to adaptations in national and international health care systems. ARIA (Allergic Rhinitis and Its Impact on Asthma) initiative develops internationally applicable guidelines for allergic respiratory diseases. In collaboration with international initiatives, ARIA offers updates of real-life integrated care pathways (ICPs) for digitally assisted, integrated, and individualized treatment of allergic rhinitis (AR).

Introduction: Although the skin prick test (SPT) is a reliable diagnostic tool in perennial allergic rhinitis (PER) for patients allergic to cats, the minimum necessary SPT wheal size required to distinguish cat sensitization from true allergy remains controversial. The cat nasal challenge test (cNCT) could be considered the gold standard for detecting true cat allergy.
Aims: To assess the difference in the frequency of cNCT positivity between cat owners and non-owners and to determine an appropriate cut-off level for SPT wheal size in detecting positive cNCT in PER patients who are candidates for allergen immunotherapy (AIT) with cat allergen extracts.
