21st century perspective on chronic obstructive pulmonary disease

Area of Science:

• Pulmonary Medicine
• Public Health
• Genetics

Background:

• Chronic obstructive pulmonary disease (COPD) is projected to be the third leading cause of death globally.
• Significant economic repercussions are associated with the rising prevalence of COPD.
• Numerous unresolved questions hinder effective COPD management and research.

Purpose of the Study:

• To highlight critical unresolved issues in COPD research and clinical practice.
• To emphasize the need for a global consensus on COPD definition and diagnosis.
• To explore potential advancements in understanding COPD's genetic basis for improved therapies.

Main Methods:

• This study is a review and discussion of existing knowledge and challenges in COPD.
• It analyzes current gaps in understanding COPD's etiology, progression, and treatment.
• It posits the potential of post-genomic and proteomic research.

Main Results:

• Lack of a worldwide consensus on COPD definition impedes comparable population studies.
• Early diagnosis of COPD remains a challenge.
• The reasons why only a subset of smokers develop COPD are not fully understood.
• Efficacy of smoking cessation interventions requires improvement.
• Reversibility of lung pathology and the overlap with asthma require further investigation.

Conclusions:

• Addressing definitional and diagnostic inconsistencies is crucial for COPD research.
• Understanding the genetic underpinnings of COPD through post-genomic and proteomic approaches may lead to more targeted and effective treatments.
• Further research is essential to improve smoking cessation interventions and clarify COPD's relationship with asthma.
