NCT03240315

Brief Summary

This is a 3-year longitudinal study designed to establish a personalized prediction and prevention system for acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Data will be prospectively collected from patients with chronic obstructive pulmonary disease (COPD) and healthy control participants, including clinical characteristics, pathophysiological parameters, etiological factors, and immunological information. These data will be analyzed using data mining approaches combined with Internet-based technologies.

Outcome Measures

Primary Outcomes (1)

  • Establishment of prediction platform for COPD exacerbation

    The patients with chronic obstruction pulmonary disease will be followed up at intervals of 3 months for 3 years by the Modified British Medical Research Council (mMRC) score scale,spirometric analysis, sputum smear,questionnaire and so on. An exacerbation of COPD was diagnosed according to GOLD guidelines. Time to the first acute exacerbation and average number of acute exacerbations per year in COPD subjects will be record.Research of AECOPD Risk factors based on complex network analysis.Identification and validation of COPD exacerbations risk stratification and predictive markers based on data mining.

    3 years

Secondary Outcomes (3)

  • Developing new protein chips for AECOPD

    3 years

  • Detection of immune repertoire in COPD/AECOPD

    3 years

  • Pathogenic microorganism and drug resistance monitoring for COPD exacerbation

    3 years

Study Arms (2)

COPD subjects

Subjects with GOLD stage I-IV COPD

Healthy control subjects

Ages 40 to 90, with no history of lung disease and no history of acute illness or medication use within the past month.

  • Known history of significant inflammatory disease, other than COPD (e.g. rheumatoid arthritis and Lupus)
  • Known to be severely alpha-1-antitrypsin deficient
  • Has experienced a moderate or severe exacerbation (requiring oral corticosteroid, antibiotics or hospitalisation) within the last 4 weeks
  • Having undergone lung surgery (e.g. lung reduction, lung transplant)
  • Have cancer or have had cancer in the 5 years prior to study entry
  • Having received a blood transfusion in the 4 weeks prior to study start
  • Inability to walk
