Comorbidities in patients with chronic obstructive pulmonary disease: a comprehensive study

Area of Science:

• Pulmonary Medicine
• Cardiology
• Endocrinology

Background:

• Chronic obstructive pulmonary disease (COPD) involves local and systemic inflammation, leading to irreversible airway obstruction.
• COPD exacerbations are frequent and often associated with comorbidities, impacting disease progression.
• Understanding these comorbidities is crucial for managing COPD's systemic effects.

Purpose of the Study:

• To determine the prevalence of comorbidities in Iraqi COPD patients.
• To investigate the association between comorbidities and COPD severity.
• To highlight the systemic nature of COPD.

Main Methods:

• A case-control study involving 200 participants (100 COPD patients, 100 controls) was conducted in Annajaf, Iraq.
• COPD patients were categorized into four severity groups.
• Prevalence of type 2 diabetes mellitus (T2DM), atherosclerotic cardiovascular diseases (ASCVD), hypertension, and dyslipidemia was assessed.

Main Results:

• COPD patients exhibited a significantly higher prevalence of T2DM, ASCVD, hypertension, and dyslipidemia compared to controls.
• Except for T2DM, the prevalence of these comorbidities increased significantly with greater COPD severity.
• T2DM, ASCVD, hypertension, and dyslipidemia are common in COPD patients.

Conclusions:

• Type 2 diabetes mellitus, atherosclerotic cardiovascular diseases, hypertension, and dyslipidemia are frequently associated with COPD.
• These comorbidities are more prevalent in patients with severe COPD, underscoring the systemic impact of the disease.
• Managing these comorbidities is essential for comprehensive COPD care.
