Fractional Exhaled Nitric Oxide (FeNO) Result Prediction Factors in Children With Allergic Diseases

Completed

• Conditions: Asthma; Allergic Rhinitis; Atopic Dermatitis
• Interventions: Procedure: measurements of lung function tests

• Registration Number: NCT00815984
• Lead Sponsor: Medical University of Lodz

Brief Summary

In about 800 children with allergic diseases (asthma, allergic rhinitis, atopic dermatitis) the investigators will retrospectively and cross-sectionally analyze the influence/correlation of diagnosis, treatment methods, allergy status (skin prick test results), lung function tests results on/with the concentration of nitric oxide in exhaled breath.

Detailed Description

In about 800 children with allergic diseases from our Outpatient Clinic (asthma, allergic rhinitis, atopic dermatitis) we will retrospectively and cross-sectionally analyse the influence/correlation of diagnosis, treatment methods, allergy status (skin prick test results), lung function tests results on/with the concentration of nitric oxide in exhaled breath.
