Pulmonary fibrosis

Introduction Pulmonary interstitial fibrosis is an inflammatory disease of the interstitial lung caused by a variety of causes. The lesion mainly affects the interstitial lung, and may also involve alveolar epithelial cells and pulmonary vessels. The cause is clear and some are unknown. The clear causes are inhalation of inorganic dust such as asbestos, coal, organic dust such as mildew dust, cotton dust, gases such as smoke, sulfur dioxide, viruses, bacteria, fungi, parasitic infections, drug effects and radiation damage. The disease belongs to the category of "cough", "hypertension" and "pulmonary sputum" of traditional Chinese medicine.

Cause

Chronic pulmonary interstitial fibrosis is an inflammatory disease of the interstitial lung caused by a variety of causes. The lesion mainly affects the interstitial lung, and may also involve alveolar epithelial cells and pulmonary vessels. The cause is clear and some are unknown.

1. Environmental factors: Inhalation of inorganic dust such as asbestos, coal, organic dust such as mildew dust, cotton dust, as well as toxic gases such as soot and sulfur dioxide.

2. Repeated infections caused by viruses, bacteria, fungi, parasites, etc., often cause the acute exacerbation of this disease, and it is also a condition for worsening the condition.

3. Drug effects and radiation damage.

4. Secondary to autoimmune diseases such as lupus erythematosus.

Pulmonary function test lung biopsy

1. Progressive urgency, dry cough, lung wet rales or sputum pronunciation.

2. X-ray examination: early glassy, typical changes in diffuse line, nodular, cloud-like, reticular shadow, lung volume reduction.

3. Laboratory examination: It can be seen that ESR and LDH increase, generally no special significance.

4. Pulmonary function test: visible lung volume reduction, diffuse function reduction and hypoxemia.

5. Lung tissue biopsy provides a pathological basis.

Differential diagnosis

This disease should be distinguished from asthmatic bronchitis. Asthmatic bronchitis, formerly known as asthmatic bronchitis, is an allergic disease that is often associated with respiratory infections. Infants and young children who occur more than 3 years old often have a history of warm rash and other allergies, especially those who are obese. The course of the disease has a long history of recurrent attacks.
