Bronchial asthma is a major cause of death, with risk factors including severity and poor management. Post-mortem investigations reveal characteristic airway changes, aiding diagnosis and understanding asthma mortality.

Area of Science:

  • Pulmonology
  • Pathology
  • Forensic Medicine

Background:

  • Bronchial asthma significantly contributes to mortality across all age groups.
  • Despite advances in understanding and treatment, asthma deaths remain a concern.
  • Effective management requires continuous surveillance and thorough post-mortem investigations.

Purpose of the Study:

  • To highlight the significance of post-mortem investigations in understanding asthma mortality.
  • To identify histological changes indicative of asthma, even when undiagnosed during life.
  • To discuss risk factors and potential mimics of asthma in fatal cases.

Main Methods:

  • Review of histological findings in fatal asthma cases.
  • Analysis of risk factors associated with asthma mortality.

  • Comparison of post-mortem findings with potential differential diagnoses.

    • Main Results:

    • Characteristic airway histological changes include basement membrane thickening, smooth muscle hypertrophy, increased vascularity, and eosinophilic infiltrate.
    • Mucoid plugging of airways is frequently observed in fatal asthma.
    • Asthma can be diagnosed post-mortem, even if missed clinically.
    • Acute severe asthma may present with pneumothorax or mediastinal emphysema.

    Conclusions:

    • Post-mortem examination is crucial for diagnosing asthma and understanding its fatal outcomes.
    • Histological evidence of airway changes aids in identifying asthma retrospectively.
    • Recognizing risk factors and differentiating asthma from mimics is essential for accurate cause-of-death determination.
