Bronchoalveolar Immune Response Determination (BIRD)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The purpose of this study is to establish if cells present in lung tissue during extrinsic allergic alveolitis (EAA) are able to elicit an immune response against specific antigens. The hypothesis is: cells in BAL lavage fluid from patients with EAA will be responsive to specific antigens and this response can be measured using ELISPOT.

Further study details as provided by Bossink, A.W.J.:

Primary Outcome Measures:
  • ELISPOT response in cells obtained from broncho-alveolar lavage [ Time Frame: 2 days ]
    All elispots will be performed the same day, the end point will be available the next day

Secondary Outcome Measures:
  • Elispot response in cells from blood [ Time Frame: 2 days ]
    ELispots will be performed the same day as blood collection, results will be available the next day

Biospecimen Retention:   Samples Without DNA
Cells obtained from Broncho alveolar lavage and blood collection

Estimated Enrollment: 25
Study Start Date: September 2011
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
non-EAA, pigeon
subject with BAL because of diseases not suspected to be EAA
EAA, pigeon
Bird fanciers with a typical clinical presentation suspected for pigeon induced EAA

Detailed Description:
Subjects suffering from extrinsic allergic alveolitis caused by pigeons will undergo a broncho alveolar lavage. Cells obtained from this BAL will be used for ELISPOT technique with pigeon specific antigens

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients suspected to have pigeon induced extrinsic allergic alveolitis will be recruited by advertisment in bird fanciers journals. Controls will be patients at the department of pulmonology and tuberculosis needing examination for other reasons

Inclusion Criteria:

  • suspicion of pigeon induced extrinsic alveolitis

Exclusion Criteria:

  • use of oral steroids
  • unable to give informed consent
  • age below 18
