Area of Science:

  • Pulmonary Medicine
  • Systems Biology
  • Biophysics

Background:

  • Asthma episode prediction is difficult, impacting patients and healthcare.
  • Classical methods rely on clinical, functional, and inflammatory variables.

Purpose of the Study:

  • Review recent insights into predicting acute asthma episodes.
  • Introduce a novel concept of asthma as a homeokinetic system.
  • Explore new methods for risk assessment.

Main Methods:

  • Summarize risk prediction attempts using clinical scores, environmental factors, and lung function.
  • Incorporate inflammatory and immunological markers (induced sputum, exhaled air).
  • Propose mathematical methods from statistical physics for dynamic system analysis.

Main Results:

  • Classical prediction methods are summarized.
  • A new concept views asthma as a complex, homeokinetic, dynamic system.
  • Fluctuation analysis of lung function time series aids in risk assessment.

Conclusions:

  • Beyond classical parameters, a new approach aids asthma control assessment.
  • This method can evaluate treatment effects individually and in trials.
  • Future research can utilize this dynamic systems perspective.
