  Purpose

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.


Condition Intervention
Rhinitis, Allergic
Asthma, Allergic
Biological: Classification as "asthmatic" or "rhinitis only" via proteomic analysis
Biological: Classification as "asthmatic" or "rhinitis only" according to a metacholine test

Primary Outcome Measures:
  • Proteomic profile of each patient [ Time Frame: One day (snapshot) ] [ Designated as safety issue: No ]
    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.


Biospecimen Retention:   Samples Without DNA

Serum and plasma samples are taken on patient inclusion. For the purposes of this study, only proteomic profiles via SELDI-TOF will be characterized. Excess serum and plasma will be stored in the CHU de Nîmes Biothèque.


Enrollment: 133
Study Start Date: May 2010
Study Completion Date: November 2012
Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
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.
