Because interstitial lung disease occurs in many patients during the development of autoimmune diseases, I have received many questions from patients and would like to give you a simple answer. Lung parenchyma refers to all levels of bronchial and alveolar structures. The interstitium refers to the supporting tissues other than the epithelium of the interalveolar and terminal bronchioles, including blood vessels and lymphatic tissue. Normal interstitium consists of two main components: cells and extracellular matrix. Interstitial lung disease (ILD) is characterized by injury or inflammatory lesions in the acute phase and fibrotic lesions in the chronic phase, mainly alveolitis. In recent years, studies have shown that the natural course of untreated patients is 2-4 years on average, but can be extended to 6 years after the application of adrenocorticotropic hormone. Regardless of whether it is early or late, treatment should be carried out immediately, so that the newly appeared alveolitis can be absorbed and improved, and part of the fibrosis can be improved and the progression of the disease can be prevented, and the first choice of drugs is corticosteroids, followed by immunosuppressant and traditional Chinese medicine.IPF is a kind of continuous development of the disease, and the principle of treatment mainly lies in actively controlling the alveolitis and making it reversible, and then preventing the progression of irreversible pulmonary fibrosis, but there is no effective treatment yet. However, there is no effective treatment so far. When choosing Chinese medicine for interstitial pneumonia, we should focus on the overall adjustment and individualized diagnosis and treatment, and there is no fixed prescription that can “cure” this disease. Whether it is traditional Chinese medicine or western medicine treatment, because they need a longer course of treatment, so there must be a doctor who can help you for a long time, pulmonary fibrosis, i.e., lung interstitial tissue is composed of collagen, elastin and protein carbohydrates, when the fibroblasts are subjected to chemical or physical injuries, they will secrete collagen for the interstitial tissues of the lungs to repair, which will cause pulmonary fibrosis; that is to say, the human body will repair the results of the injuries suffered by the lungs. This is the result of the body’s efforts to repair the lungs after they have been injured. Usually when the hormone response is poor or contraindicated, then add or change cyclophosphamide, there are many immunotherapy, but the improvement is mainly for the improvement of lung function, but the conclusion of whether the fibrosis can be improved are not the same, traditional Chinese medicine reports more, and there are many treatments in many parts of the process is also very helpful, but in general there are also more cases, but also have to be with the symptoms and the combination of the individual situation. My personal opinion is helpful, the key is that this is a disease that requires long-term treatment, and the patient’s family hope are just one side of a drug gap is too far. Family members began to heart are very anxious, always want to prescribe a party with a drug can be treated, and then they are not serious, the doctor’s opinion is not too much attention to this kind of disease treatment is not the main reason for the success of the treatment. Of course, the spirit should maintain a happy and optimistic mood, to prevent mental stimulation and mental overstress. Keep away from exogenous allergens, rehabilitation therapy interstitial fibrosis patients’ recovery is also very important, including a variety of life conditioning, which is a doctor-patient long-term cooperation project.
