Clinical Presentation and Outcome of COPD Patients With Acute Exacerbation Attending Sohag University Hospital

Chronic obstructive pulmonary disease (COPD) is a worldwide public health challenge because of high prevalence and related disability and mortality (1).

Acute exacerbation of COPD (AECOPD), defned as the worsening of respiratory symptoms and requirement of additional clinical treatment, it reduces lung function and quality of life, and is accompanied by an increased disease-related burden, high hospital mortality and poor outcome (2).

Chronic obstructive pulmonary disease frequently coexists with other chronic diseases, namely comorbidities. They negatively impact prognosis, exacerbations and quality of life in COPD patients. Local and systemic inflammation have been proposed as having a potential role in explaining the association between COPD and these comorbidities (3).
