Disease description (causes and symptoms)
- Definition and pathophysiology: Pleurisy is a condition in which the two layers of pleura surrounding the lungs become inflamed. Friction between the pleural surfaces due to inflammation or pleural fluid causes chest pain and shortness of breath. A pleural friction rub (frictio pleuralis) or pleural fluid (pleural effusion) may occur, and prolonged inflammation can leave pleural adhesions that cause chronic shortness of breath.
- Main causes: Viruses (colds·influenza), bacterial pneumonia, pulmonary embolism, tuberculosis (tuberculous pleurisy), malignant tumors (metastatic pleural cancer), and autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, etc.).
- Main symptoms: Sharp chest pain that worsens during inhalation (chest pain), shortness of breath, cough, sputum, fever·chills, and malaise. If pus accumulates in the pleura (empyema), the pain may temporarily improve.
Treatment methods
- Treatment of the cause (applied after first determining the cause)
- Bacterial pneumonia: Administration of appropriate antibiotics (selected according to culture and antimicrobial resistance results).
- Tuberculous pleurisy: Standard anti-tuberculosis drug regimen (compliance with medication for the designated period is necessary).
- Pulmonary embolism-related: Anticoagulant therapy (and, when necessary, thrombolysis, etc.).
- Autoimmune-related: Prescription of steroids·immunosuppressants, etc., by a rheumatologist.
- Malignant pleural disease: Oncologic treatment (anticancer therapy·radiation·surgery, etc.) and symptomatic treatment.
- Symptomatic treatment
- Reducing pain·inflammation: Nonsteroidal anti-inflammatory drugs (NSAIDs) or, when necessary, short-term use of opioids.
- Shortness of breath·pleural effusion: Thoracentesis (for diagnostic·relief purposes), chest tube insertion (indwelling) or pleural drainage for large pleural effusions or infection, and chest tube drainage for empyema, with intrapleural fibrinolytics (administration)·surgical drainage when appropriate.
- Recurrent·repeated pleural effusion: Pleurodesis or surgical treatment (such as partial pleurectomy) may be considered.
- Lifestyle management and precautions
- Prevent atelectasis through smoking cessation and regular breathing exercises (deep breathing·inducing coughing).
- Visit the emergency room immediately in cases of high fever·shortness of breath·signs of tension.
- If the condition is tuberculous, take the prescribed anti-tuberculosis drugs until the end and follow the medical team's instructions.
Checklist before an outpatient visit (including example questions)
- Items to prepare
- A list of medications currently being taken (including prescription·nonprescription drugs·herbal medicines) and the most recent doses
- Medical history (tuberculosis, thrombosis, autoimmune disease, cancer), and history of surgery·hospitalization
- Recent chest imaging (chest X-ray, CT)·blood test results (copies, if available)
- Symptom record: time of onset, characteristics of the pain (location·nature·changes with breathing·position), presence of fever, sputum color·amount, and degree of shortness of breath (during activity·at rest)
- Risk factors: recent long-distance travel·prolonged bed rest·exposure to respiratory infections·contact with tuberculosis
- Examples of questions that are useful to confirm during an outpatient visit (questions the patient should prepare in advance)
- What tests are needed for my current symptoms (chest X-ray/CT/pleural fluid tests/blood tests)?
- What symptoms require me to go to the emergency room immediately (shortness of breath·coughing up blood·high fever, etc.)?
- What are the side effects·drug interactions of the medications that are likely to be prescribed?
Examples of general questions to ask the doctor
- What do you think is causing this? What additional tests do I definitely need to have?
- What treatment options are recommended for my symptoms, and what is the expected treatment duration?
- What are the main side effects of the prescribed medication, and what should I be careful about in daily life (alcohol consumption·exercise·driving, etc.)?
- How likely is recurrence, and what should I do to reduce the risk of recurrence?
Examples of disease-specific questions
- If tuberculous pleurisy is suspected: Is anti-tuberculosis drug treatment necessary, how long will treatment last, and is it infectious (is isolation from family members·people living together necessary)?
- If an association with pulmonary embolism is suspected: Which medications should additionally be avoided (e.g., those that interact with anticoagulants), and how long should anticoagulant treatment last?
(Clinical decisions and treatment are based on the diagnosis and test results provided by the attending doctor. If emergency symptoms occur, such as worsening shortness of breath, a sharp increase in chest pain, or decreased consciousness, visit an emergency medical institution immediately.)
