Causes of acute interstitial pneumonia

The causes of acute interstitial pneumonia mainly include infection, drugs, autoimmune diseases and idiopathic, specific analysis: infection: virus, bacteria, fungi and other infections can be caused. Drugs: some drugs can cause. Autoimmune diseases: systemic lupus erythematosus and other autoimmune diseases can involve the lungs. Idiopathic: unknown cause. The causes of acute interstitial pneumonia are complex, mainly including infection, drugs, autoimmune diseases, idiopathic, etc. The following is a specific analysis of these causes: 1. Infection: Virus, bacteria, fungi and other infections can lead to acute interstitial pneumonia. For example, viral infections such as adenovirus, influenza virus, Mycoplasma pneumoniae, bacterial infections such as Streptococcus pneumoniae, Haemophilus influenzae, and fungal infections such as Pneumocystis may cause the disease. 2. Drugs: Certain drugs can also cause acute interstitial pneumonia. These drugs include antibiotics, antiarrhythmic drugs, and antineoplastic drugs. Drug allergy or adverse reactions are the main causes of drug-induced acute interstitial pneumonia. 3. Autoimmune diseases: autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and Sjogren's syndrome can involve the lungs and lead to acute interstitial pneumonia. The production of autoantibodies and the deposition of immune complexes are one of the pathogenesis. 4. Idiopathic: Acute interstitial pneumonia of unknown cause is called idiopathic acute interstitial pneumonia. At present, it is believed that it may be related to genetic factors and environmental factors. In short, the causes of acute interstitial pneumonia are various. Diagnosis requires comprehensive consideration of the patient's clinical manifestations, imaging examinations, pulmonary function tests, etc., and analysis combined with possible causes. For patients suspected of acute interstitial pneumonia, should seek medical attention in time, in order to make a clear diagnosis and take appropriate treatment measures. Warm tip: acute interstitial pneumonia may lead to respiratory failure and other serious complications, even life-threatening. Therefore, for patients with acute interstitial pneumonia, should actively cooperate with the doctor treatment, while paying attention to rest, nutritional support, etc.
