Atopy Network - Comprehensive Allergy Centers: Medical Care of Patients With Moderate to Severe Allergic Diseases (ATAC)

The Atopy Registry aims to assess data about atopic disorders and their medical care in a standardized form. With this, the comparative efficacy, tolerability and safety of systemic therapies for atopic disorders should be investigated. An optional additional module "Bioanalytic" shall provide insights into further connections regarding immunology, genetics and microbiome.

Study Overview

• Status: Recruiting
• Conditions: Atopic Disorders
• Intervention / Treatment: Other: not applicable, observational study

Detailed Description

The prevalence of atopic disorders increased in the western countries within the past decades. Atopic disorders are among others: food allergy, atopic dermatitis, allergic rhinitis, bronchial asthma, chronic spontaneous urticaria, eosinophilic esophagitis and chronic rhinosinusitis with nasal polyposis.

Seriously affected patients often have coexisting atopic disorders. In fact, 60-75% of the patients with a severe atopic dermatitis also suffer from an allergic rhinoconjunctivitis and 40-50% from bronchial asthma. This leads to a decreased quality of life (LG) especially in seriously affected patients.

The treatment of atopic disorders is not standardized yet. The Atopy Registry should promote the creation of a Germany-wide registry for different atopic disorders.Furthermore, the registry should characterize the medical care of patients with atopic disorders (patient satisfaction, therapy order, treatment success). This study serves as a longterm observation und is designed to compare different systemic therapies, since head-to-head studies regarding the efficacy are still missing. The analysis of biomaterial is involved to state possible correlations between endotype and phenotype.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Comorbidity Food Allergy	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Food Allergy: Food Allergy Quality of Life Questionnaire (FAQLQ) (type-dependent 23-30 items, score between 0 and 6; mean of scores, minimum = 0, maximum = 6; higher score = higher impact on quality of life)	3 years
Comorbidity Atopic Dermatitis	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Atopic Dermatitis: Atopic Dermatitis-Control-Test (ADCT) (6 items, score between 0 and 4; sum, minimum = 0, maximum = 24; higher score = higher severity)	3 years
Comorbidity Bronchial Asthma	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Bronchial Asthma: Asthma-Control-Test (ACT) (5 items, score between 0 and 5; sum, minimum = 0, maximum = 25; higher score = better disease control)	3 years
Comorbidity Chronic rhinosinusitis with nasal polyps	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Chronic rhinosinusitis with nasal polyps: 22 Items Sino-Nasal Outcome Test (SNOT22) (22 items, score between 0 and 5; sum, minimum = 0, maximum = 110; higher score = higher impact on quality of life)	3 years
Comorbidity Chronic Spontaneous Urticaria	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Chronic Spointaneous Urticaria: Urticaria Control Test (UCT) (4 items, score between 0 and 5; sum, minimum = 0, maximum = 20; higher score = better control)	3 years
Comorbidity Eosinophilic Esophagitis	Improvement of at least one comorbidity with biologics therapy using a standardized questionnaire to assess disease severity for the following atopic diseases: Eosinophilic Esophagitis: Dysphagia Symptoms Questionnaire (DSQ) (4 items, score between 0 and 4 but question-dependent; sum, minimum = 0, maximum = 10; higher score = higher impact)	3 years
