Study Notes
Classification of Pneumonia
-
Community-Acquired Pneumonia (CAP)
- Occurs outside of a hospital or within 48 hours of admission.
- Common pathogens: Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus.
- Viruses are involved in about 10% of cases.
- In those with existing lung diseases (e.g., COPD), Pseudomonas aeruginosa and Moraxella catarrhalis are prevalent.
-
Atypical Pneumonia
- Can be acquired in the community or institutions.
- Caused by: Mycoplasma, Legionella, Chlamydia species.
-
Hospital-Acquired Pneumonia (HAP)
- New-onset pneumonia occurring 48 hours or more after hospital admission.
- Common causative agents include Gram-negative bacteria like Pseudomonas and Klebsiella.
-
Aspiration Pneumonia
- Results from aspiration of gastric contents due to inability to protect airway.
- Often involves anaerobic organisms.
- Stroke patients are particularly at risk.
-
Opportunistic Pneumonia
- Increased risk in individuals with cystic fibrosis due to airway mucus changes, leading to Pseudomonas infections.
- Patients with compromised immune systems (e.g., HIV+) are at higher risk of fungal pneumonia.
Classification by Area Affected
-
Lobar Pneumonia
- Typically involves a single lobe.
- Common causative agents: Streptococcus pneumoniae, Klebsiella pneumoniae, Haemophilus influenzae.
- Symptoms: Rapid onset, high fever, productive cough with rusty-colored sputum.
-
Bronchopneumonia
- Characterized by multiple patches throughout the lungs.
- Common causative agents: Staphylococcus aureus, Pseudomonas aeruginosa.
- Symptoms: Insidious onset, low-grade fever, productive cough, scattered rales, and ronchi.
Causes of Pneumonia
-
Bacterial
- Most common cause; includes pathogens like Streptococcus pneumoniae and Klebsiella pneumonia.
-
Viral
- Common viruses: Influenza, Coronavirus, Respiratory Syncytial Virus.
-
Fungal
- Pathogens include Histoplasma capsulatum, Aspergillus fungi.
-
Chemical
- Caused by direct injury from irritants like kerosene or chlorine gas.
-
Inhalation
- Results from aspiration leading to chemical lung injury from gastric contents.
Clinical Features
-
Typical Pneumonia
- Symptoms: High fever (39.5 – 40.5°C), chills, tachypnea, dyspnea, pleuritic chest pain, productive cough with rusty sputum.
- Physical signs include dullness upon percussion, increased vocal resonance, and bronchial breath sounds.
-
Atypical Pneumonia
- Gradual onset, dry cough, and extrapulmonary symptoms like headaches, muscle pain, and gastrointestinal issues.
Diagnosis
- Diagnosis involves a combination of patient history, physical examination, and instrumental diagnostics (e.g., chest X-ray).
- Physical examination may reveal crepitations, bronchial breathing, and dull percussion sounds.
Risk Factors and Vulnerabilities
- Individuals with systemic lupus erythematosus, long-term corticosteroid use, and those with a history of alcohol abuse are at higher risk for specific types of pneumonia.
- Patients on respiratory support are at increased risk of ventilator-associated pneumonia (VAP) often caused by Pseudomonas or Klebsiella.
Important Notes
- Individuals with underlying respiratory conditions are more susceptible to secondary infections and severe complications.
- Understanding the type of pneumonia is critical for effective treatment and management strategies.
