Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The majority of asthmatic patients are well controlled by inhaled corticosteroid treatment, however some severe asthma resist this treatment. CCL18 is a target gene for corticosteroids and its dysfunction may correlate with phenotypes of asthma.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. control subjects =

* non-atopic and non-smoking
* cutting to negative pneumoallergens,
* Total IgE levels less than 100 ku / L
* no clinical history of asthma
* without background treatment
2. patients with intermittent asthma =

* being asymptomatic between asthma attacks,
* with symptoms less than once a week
* having a forced expiratory volume per second (FEV1) of at least 80% of the theoretical.
* treated by ß2 mimetics on demand and will not have inhaled corticosteroids.
3. severe asthma insensitive to corticosteroid therapy =

* continuous or nearly continuous treatment with oral corticosteroids (≥ 50% of the year) / or treatment with IC ≥ 1500 microg beclomethasone dipropionate equivalent (BDP)\] airway obstruction fixed with FEV1 ranging from less than 15% after 7 days of oral corticosteroid therapy to 40 mg / day of prednisolone;
* Followed at the immunoallergology pneumology consultation for at least 1 year will be recruited.
4. Severe corticosensitive asthma = continuous or near continuous treatment with oral corticosteroids (≥ 50% of the year) / or treatment with IC ≥ 1500 microg beclomethasone dipropionate equivalent (BDP)\]

* reversibility of FEV1 after treatment with oral corticosteroids.
* Followed at the immunoallergology pneumology consultation for at least 1 year will be recruited.
5. controlled moderate asthma treated with inhaled corticosteroids \<1500μg equivalent of beclomethasone dipropionate and with: ß2 long-acting mimetics (or anti-leukotriene, or theophylline) for at least 6 months.

Exclusion Criteria

* existence of a chronic inflammatory pathology other than asthma
* active smoking
* pregnant or lactating women
* have received oral corticosteroid treatment in the previous 3 weeks,
* have received non-steroidal anti-inflammatory drugs (NSAIDs) in the previous 2 weeks.
