Validation of the Cholinergic Urticaria Activity Score (CholUAS).
Background: In cholinergic urticaria (CholU), itchy wheal and flare-type skin reactions are triggered by sweat-inducing activities. The CholU activity score (CholUAS) is used to assess disease activity but has not yet been validated. The aim of the study was to validate the CholUAS, develop an English version, and provide instructions for scoring.
Methods: Cognitive debriefing of CholUAS was performed. Patients with CholU (n = 75) used the CholUAS on 7 consecutive days, underwent provocation testing, completed additional anchor instrument questionnaires including global evaluation tools, and established quality of life instruments. A scoring protocol for the calculation of the weekly CholUAS, the CholUAS7, was developed. The CholUAS7 was tested for validity, reliability, and influencing factors. An English version of the CholUAS was developed.
Results: The final CholUAS contains 3 questions that are used for scoring as well as 1 global question. The weekly CholUAS, CholUAS7, showed excellent test-retest reliability and good correlations with anchor instruments. Statistical analysis showed no significant influence of age or duration of disease on CholUAS7 results.
Conclusion: The validated CholUAS is ready for use in clinical trials and routine clinical practice.
期刊介绍:
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
