OVERVIEW OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE
Description
Background: Chronic Obstructive Pulmonary Disease (COPD) is a complex disease influenced by both genetic and environmental factors, leading to irreversible lung damage, systemic complications, and a significant global health burden. Effective diagnosis, management, and adherence to treatment guidelines are essential to alleviate the burden on patients and improve outcomes.
Aim: The present study aims to review the update on Chronic Obstructive Pulmonary Disease.
Methods: Comprehensive research of COPD. PUBMED and Google Scholar search engines were the databases used for the search process, and articles were collected from 2013 to 2023. The terms used in the search were COPD, risk factors, Pathophysiology, Manifestations, Diagnosis, treatment, and Exacerbation.
Conclusion: COPD is a prevalent and progressive lung condition characterized by irreversible airflow obstruction, inflammation, and damage to lung tissue. The main subtypes are chronic bronchitis and emphysema. COPD is influenced by both genetic and environmental factors, with cigarette smoke being a primary risk factor. It is associated with systemic inflammation and comorbidities like cardiovascular diseases, diabetes, and muscle weakness. Viral infections, particularly influenza A viruses, can trigger acute exacerbations. The pathophysiology involves oxidative stress, altered immune response, and inflammation, leading to chronic bronchitis, emphysema, and small airway disease. Diagnosis includes spirometry, pulmonary function tests, and clinical factors, with various laboratory and imaging tools aiding in confirmation. Treatment strategies encompass pulmonary rehabilitation, pharmacologic therapies (bronchodilators, corticosteroids), surgical interventions, and oxygen therapy. Vaccinations are recommended, and careful management of exacerbations involves oxygen therapy, inhaled antibiotics, and corticosteroids. Smoking cessation is crucial, and newer therapies like stem cell-based treatments show promise.
