What are the manifestations of diffuse interstitial lung disease

You may not know much about diffuse interstitial lung disease. This disease is a type of respiratory disease with complex pathogenic factors. Due to the many causes of this disease, it is difficult to diagnose and identify. After suffering from this disease, the symptoms are similar to those of general lung diseases, namely shortness of breath, shortness of breath, dry cough, chest pain, etc., and they must be distinguished from general lung diseases during diagnosis.

Diagnosis and Differential Diagnosis of Diffuse Interstitial Lung Disease

1. Symptoms and medical history Interstitial lung disease has an insidious onset and progressive worsening. Some patients are discovered during routine chest X-ray or radiography during physical examination, and most seek medical treatment due to shortness of breath during activities. The main symptom is progressively worsening shortness of breath and, less commonly, dry cough, chest pain, or hemoptysis. In the late stage, respiratory failure manifested by hypoxemia often occurs.

The medical history can also help diagnose the cause of interstitial lung disease. Such as occupational history, history of exposure to dust or harmful gases. Whether you take certain medications. Interstitial lung disease may be a pulmonary manifestation of some systemic diseases, and relevant medical history should also be inquired, such as the presence or absence of clinical manifestations of collagen-vascular disease.

(B) Physical examination revealed weakened thoracic respiratory movement, with fine moist rales or crackles audible in both lungs, most prominent at the lung bases. Dry rales are rarely heard. There are no abnormalities in the heart in the early stage, but later a hyperactive second heart sound in the pulmonary valve area may be heard. In the late stage, there may be symptoms of right heart hypertrophy or right heart failure. Clubbing of the fingers and toes and cyanosis of the oral mucosa may also be found.

3. Laboratory tests: Blood tests are not important for the diagnosis, grading and activity of interstitial lung disease. However, in order to clarify the cause and differential diagnosis, corresponding examinations should be performed. Such as examinations related to collagen-vascular diseases, cardiac function tests to exclude pulmonary edema, pathogen tests to exclude lung infection, etc.

(IV) X-ray examination: Although 5% to 10% of diffuse interstitial lung disease confirmed by lung biopsy shows no abnormal findings on plain X-ray films, the frontal and lateral chest radiographs are still the main means of diagnosing diffuse interstitial lung disease. Early lesions may appear ground-glass, and typical changes are linear, nodular, nodular reticular or reticular shadows. In severe cases, honeycomb-like changes may occur.
