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.
