Official Title: Interest of TARC Serum Marker for Follow-up of Patients With Allergic Broncho-Pulmonary Aspergillosis (ABPA), Excluding Cystic Fibrosis
Brief Summary:
The main objective of this study is to determine if a doubling of serum TARC (compared to baseline) is associated with the occurrence of exacerbations of ABPA.
The secondary objectives of the study are :
- To investigate if induced sputum eosinophils count (compared to baseline) is associated with the occurrence of exacerbations.
- To examine if the exhaled NO (compared to a baseline) is associated with the occurrence of exacerbations.
- To investigate if activation of circulating T cells (compared to a baseline) is associated with the occurrence of exacerbations.
- To examine if the rate of specific Asp f IgG measured by ELISA (compared to a baseline) is associated with the occurrence of exacerbations.
- To determine if the variation of one of the markers above, TARC or Asp f specific IgE measured at baseline, may be associated with the radiological stage of the disease (ABPA-S, ABPA-CB, ABPA-ORF).
- To investigate if there is a link between fungal exposure at home (visually assessed by the contamination level and the proportion of positive samples for Asp. f) and the frequency of exacerbations.
- To establish if some of the clinical, functional or biological data studied are associated with the frequency of exacerbations.
