NCT03278561

Brief Summary

A cross-sectional study in asthma patients to determine if a late age of onset asthma (start symptoms \>18 years old), is associated with more persistent airway/systemic inflammation, worse asthma control, more co-morbidity, a different microbiome and poorer quality of life despite the use of optimized asthma therapy.

Sampling MethodProbability Sample
Study Population

The aim is to enrol 30 patients with early onset asthma (age of onset \< 18 years) and 30 patients with late onset asthma (age of onset \> 18 years); all with a smoking history of \< 10 PY. Both groups consist of 15 older asthma patients (\> 50 years) and 15 younger asthma patients (\< 50 years); per age group 15 healthy controls serve as comparison (no asthma). Asthma diagnosis is based on presence of typical clinical symptoms, reversible airway obstruction (+12% improvement in FEV1 after bronchodilator) or bronchial hyperreactivity (PC20 \< 8 mg/ml) or a FeNO \> 50 ppb. All asthma patients have GINA step 4-5 medication (high dose ICS/LABA) and are not adequately controlled (ACQ \> 0,75)

You may qualify if:

  • Age between 18-80 years
  • Smoking history of \< 10 packyears (PY)
  • Willing and able to comply with the study protocol
  • Asthma diagnosis is based on presence of typical clinical symptoms, reversible airway obstruction (+12% improvement in forced expiratory volume at one second (FEV1) after bronchodilator) or bronchial hyperreactivity (PC20 \< 8 mg/ml) or a (fractional exhaled nitric oxide) FeNO \> 50 ppb. - All asthma patients have (Global Initiative for Asthma ) GINA step 4-5 medication (high dose ICS/LABA).
  • Asthma control questionaire (ACQ) \> 0,75
  • Written informed consent.
  • Written informed consent
  • Age between 18-80 years.

You may not qualify if:

  • Smoking history of \> 10 PY
  • Age \< 18 years or \> 80 years
  • Not able to speak or write Dutch language.
  • Not able to perform lung function test/sputum induction
  • ACQ \< 0,75
  • Other diseases which could influence pulmonary function and/or the immune system such as: o A possible infection of the upper- or lower respiratory tract 4 weeks prior to the collection of materials;
  • Chronic obstructive pulmonary disorder (COPD) in the medical history;
  • Auto-immune diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), myasthenia gravis or Goodpasture's syndrome;
  • Malignancies;
  • Inherited or acquired immunodeficiency
  • Pregnancy;
  • Asthma, as defined earlier (page 13);
  • An abnormal spirometry with a forced vital capacity (FVC) or FEV1 below the 80% of the predicted value
  • A liaison with the coordinating or principal investigator, which could likely influence the decision to participate in this study voluntarily (in concordance with the World Meteorological Organization (WMO) -article 5);
