No results posted yet for this study

Summary

The aim of the study is to investigate the influence of chewing gum consumption on FeNO levels in asthma patients in order to avoid systematic errors in treatment decisions.

Conditions

  • Asthma Bronchiale
  • FeNO
  • Chewing Gum

Interventions

OTHER

Chewing Gum

Patients admitted to our outpatient clinic for bronchial asthma undergo regular FeNO measurements. If the value is ≥ 25 ppb (elevated), the patients are randomized into two groups after obtaining their consent. In the control group, a FeNO measurement is performed again after 15 minutes. In the second group, the FeNO measurement is measured again after 15 minutes of consuming sugar-free, antioxidant-containing chewing gum. The following data are then collected and documented from the patients: age, gender, height, weight, smoking status, current medication, other illnesses, whole body lung function test, and laboratory tests (eosinophils, IgE). Participation in the study will not change the course of the patient's stay in our clinic.
