Study Notes

Chronic Obstructive Airway Diseases

Defined as a chronic, slowly progressive airway disease characterized by irreversible damage to the airways.
Abnormal dilation of airways distal to the terminal bronchioles indicates a specific type of airway disease.
Chronic bronchitis is a common cause of this condition and is often associated with infections.

Pathophysiology

Infection, particularly with Staphylococcus aureus, can result in low white blood cell (WBC) counts due to the destruction of WBCs by the infection's coagulase enzyme.
Inflammation leads to compression of alveolar ducts and sacs, causing early symptoms.

Clinical Presentation

Early symptoms include a painful, dry cough, wheezing, and dyspnea (breathlessness).
Continuous inflammation can lead to further complications such as pus accumulation and increased inflammatory processes.
Erosion of blood vessels (B.V) may cause hemoptysis (coughing up blood) and can lead to complications such as right heart failure (cor pulmonale).
Erosion and rupture of alveoli result in productive cough characterized by the expulsion of mucus.

Diagnostic Indicators

Bone marrow suppression due to pus formation can lead to pancytopenia, affecting hemoglobin (Hb), WBC, and platelets (PLT).
Elevated Erythrocyte Sedimentation Rate (ESR) indicates ongoing inflammation, typically rising above 100.

Symptomatic Features

Initial flu-like symptoms can occur, which may progress over time.
Dyspnea develops as 90% of patients experience progressively worsening shortness of breath.
