A child with asthma experienced worsened lung function from standard bronchodilator tests. However, inhaled disodium cromoglycate (DNCG) with salbutamol effectively normalized his lung function, offering a novel treatment approach.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Medicine
  • Clinical Case Study

Background:

  • Asthma bronchiale is a chronic respiratory condition often managed with bronchodilators.
  • Post-pleuropneumonia asthma can present unique challenges in treatment.
  • Standard bronchodilator testing is crucial for assessing airway reactivity.

Observation:

  • A 10-year-old boy with asthma post-pleuropneumonia showed paradoxical reactions to inhaled saline with salbutamol or ipratropium bromide.
  • Increasing doses of inhaled salt solutions up to 1.4% induced severe bronchoconstriction in the patient.
  • This case highlights an unusual response to common inhalation therapies.

Findings:

  • Bronchospasmolysis tests using physiological saline combined with salbutamol or ipratropium bromide unexpectedly impaired lung function.

  • Inhalation of disodium cromoglycate (DNCG) in conjunction with salbutamol completely normalized lung function.
  • This suggests a potential hypersensitivity to hypertonic saline in this specific patient.

    • Implications:

    • The findings suggest that standard bronchodilator protocols may not be universally applicable, especially in complex pediatric asthma cases.
    • Disodium cromoglycate (DNCG) may represent a viable alternative or adjunctive therapy for managing bronchoconstriction in similar patients.
    • Further research is warranted to explore the mechanisms behind hypertonic saline-induced bronchoconstriction and the efficacy of DNCG in such scenarios.
