Validation of Proteomic Analyses for Allergic Asthma and Rhinitis (VAPARA)

March 26, 2015 updated by: Centre Hospitalier Universitaire de Nīmes

The VAPARA Study: Validation of Proteomic Analyses for Allergic Asthma and Rhinitis

The purpose of this study is to verify and validate the intrinsic diagnostic value in terms of sensitivity and specificity of proteomic profiles determined during a pre-study for discriminating between allergy related asthma and allergy related rhinitis.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
All patients
Allergy patients, asthma and rhinitis
Biological: Classification as "asthmatic" or "rhinitis only" via proteomic analysis
Proteomic profiles are established for each patient using plasma and serum samples
Biological: Classification as "asthmatic" or "rhinitis only" according to a metacholine test
A positive metacholine test indicating bronchial hyperresponsiveness is currently our Gold Standard for diagnosing asthma.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proteomic profile of each patient
Time Frame: One day (snapshot)
The attribution of a proteomic profile as either "asthmatic" or "rhinitis". Proteomic profiles are determined accordig to the SELDI-TOF method. This is a transversal study validating proteomic profiles as a new diagnostic test.
