    Oesophageal dysfunction (OD) is common in asthma patients, particularly those with exogenous asthma. Patients with OD experience more severe respiratory symptoms like productive cough and wheezing.

    Area of Science:

    • Gastroenterology
    • Pulmonology
    • Clinical Medicine

    Background:

    • Oesophageal dysfunction (OD) encompasses conditions like hiatal hernia, dysmotility, and lower oesophageal sphincter (LES) hypotension.
    • Asthma is a chronic respiratory disease often associated with various comorbidities.
    • The relationship between OD and bronchial asthma requires further investigation.

    Purpose of the Study:

    • To investigate the frequency of different types of oesophageal dysfunction (OD) in patients with bronchial asthma.
    • To determine if there is a correlation between OD and the type (exogenous vs. endogenous) and duration of asthma.
    • To assess the impact of OD on respiratory symptoms in asthma patients.

    Main Methods:

    • A study was conducted on 97 patients diagnosed with bronchial asthma.

  • Patients underwent manometry and acid perfusion tests to diagnose OD.
  • Data on asthma history, type, and respiratory symptoms were collected and analyzed.

    • Main Results:

    • 36 patients had hiatal hernia, 37 dysmotility, 26 LES hypotension, and 23 a positive acid perfusion test.
    • OD was significantly more prevalent in exogenous asthma (95%) compared to endogenous asthma (58%).
    • Asthma patients with OD reported more frequent productive cough and wheezing (46%) than those without (19%).

    Conclusions:

    • Oesophageal dysfunction is frequently observed in bronchial asthma patients.
    • Exogenous asthma is associated with a higher incidence of OD.
    • OD may exacerbate respiratory symptoms in asthma patients, indicating a need for integrated management approaches.
