NCT03779152

Brief Summary

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.

Study Population

patients consulting for either asthma or chronic rhinitis and meeting the criteria of the control group.

You may qualify if:

  • 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
  • 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.
  • 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.
  • 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)\]
  • +3 more criteria

You may not qualify if:

  • 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.
