pleurisy etiology

Pleurisy can be caused by bacteria, viruses, tuberculosis and other infections, or autoimmune diseases, malignant tumors, drugs and other non-infectious factors, in addition, malignant pleural effusion, pleural pressure changes, iatrogenic factors may also lead to pleurisy. Pleurisy is a common disease, can be caused by a variety of causes. The following is a specific analysis of the causes of pleurisy: 1. Infections due to bacterial infections: pneumonia, tuberculosis, lung abscess and other lung infections can directly involve the pleura, or cause pleurisy through blood dissemination. Viral infections: such as influenza virus, herpes zoster virus, etc. can cause viral pleurisy. Tuberculosis infection: tuberculosis can infect the pleura through respiratory tract inhalation, blood circulation and other ways, resulting in tuberculous pleurisy. Other pathogen infections: such as mycoplasma, chlamydia, fungi, etc. can also cause pleurisy. 2. Non-infectious diseases due to autoimmune diseases: systemic lupus erythematosus, rheumatoid arthritis, Sjogren's syndrome and other autoimmune diseases can involve the pleura, leading to pleurisy. Malignant tumors: Lung cancer, breast cancer, esophageal cancer and other malignant tumors can be transferred to the pleura, or direct invasion of the pleura caused pleurisy. Drugs: certain drugs such as penicillin, sulfa drugs can cause allergic reactions, leading to pleurisy. Trauma: chest trauma, surgery, etc. can lead to pleurisy. Other: uremia, heart failure, sarcoidosis, etc. can also cause pleurisy. 3. Other factors Malignant pleural effusion: lung cancer, breast cancer and other malignant tumors can lead to pleural effusion, some patients may appear pleurisy. Intrapleural pressure changes: such as chronic obstructive pulmonary disease, pneumothorax, etc. can lead to intrapleural pressure changes, affecting pleural blood circulation and metabolism, thus causing pleurisy. Iatrogenic factors: such as pleural puncture, radiotherapy, etc. can cause pleurisy. In short, the etiology of pleurisy is complex and diverse, infectious and non-infectious causes can cause pleurisy. For pleurisy patients, detailed examination and diagnosis should be carried out according to the specific circumstances to clarify the cause, and take corresponding treatment measures. At the same time, for high-risk groups, such as the elderly, immunocompromised persons, etc., attention should be paid to preventing the occurrence of pleurisy. It should be noted that the above is for reference only. Please diagnose and treat under the guidance of a doctor. If you or someone around you has pleurisy related symptoms, it is recommended to seek medical attention in time for early diagnosis and treatment.
