Causes of Tuberculous Pleural Effusion

The main causes of tuberculous pulmonary effusion are as follows: 1. Tuberculosis infection: Mycobacterium tuberculosis enters the body through the respiratory tract, infects the lungs, triggers an inflammatory response, leading to excessive inflammatory secretions from the lung mucosa, and eventually forming pulmonary effusion. 2. Spread of tuberculosis lesions: When Mycobacterium tuberculosis spreads from existing tuberculosis foci, it may cause an inflammatory response in surrounding tissues, resulting in pulmonary effusion. 3. Secondary pleuritis: Other diseases, such as pneumonia and pulmonary embolism, may cause secondary pleuritis, leading to fluid accumulation in the pleural cavity and forming pulmonary effusion. Among the above causes, tuberculosis infection is the most significant. For tuberculous pulmonary effusion, treatment mainly involves anti-tuberculosis medications such as isoniazid and rifampin, along with symptomatic treatments such as drainage of pleural effusion. At the same time, patients should maintain healthy lifestyle habits, enhance their immunity, and promote recovery.
