Does tuberculosis cause pulmonary fibrosis?

Pulmonary tuberculosis fibrosis is one of the outcomes of pulmonary tuberculosis, when the inflammatory process of pulmonary tuberculosis is controlled, and the necrosis of lung tissue is absorbed, the body will repair itself at the original lesion site, and in this process, fibrous tissue proliferation is the main one, forming different degrees of pulmonary tissue fibrosis. It can be understood as a sign that the disease is improving. Of course, excessive fibrosis can lead to impaired lung function.

So you should go for a follow-up examination at the time the doctor instructed.

The new crown is the new coronavirus pneumonia, referred to as the new crown pneumonia, the impact of the new crown pneumonia on the human body may be relatively large, the patient may have pulmonary fibrosis, severe cases and even death.

If infected with new crown pneumonia, the main clinical manifestations are fever, fatigue, and dry cough, and the patient will have the following conditions:

1. Patients with new crown pneumonia will have abnormal lung function, such as dyspnea, cough, bronchiectasis and pulmonary fibrosis.

2. The novel coronavirus may attack nerve cells in the brain, and then a series of neurological symptoms may appear, such as difficulty concentrating, memory loss, cognitive impairment, tanki trace taste disorder, smell disorder, and headache. Patients with severe COVID-19 are more likely to have ischemic stroke, and the occurrence of stroke may further lead to a poor prognosis in these patients, and some patients may die from stroke.

3. The new crown pneumonia may affect the digestive system, and patients may have symptoms such as decreased appetite, nausea, vomiting, diarrhea, abdominal pain, abnormal liver enzymes, etc., and severe patients may have gastrointestinal bleeding.

4. Women may experience minor discomforts such as sleep disorders, hair loss, and joint pain, and men's fertility may be damaged to a certain extent.

The common sequelae of pulmonary fibrosis include fibrosis of the lungs, mild decline in cardiopulmonary function, fatigue and muscle weakness, resulting in reduced labor capacity and exercise tolerance. It can also cause mild psychological dysfunction, such as insomnia, anxiety or depression.

Severe sequelae can include severe pulmonary dysfunction, respiratory failure, liver insufficiency, renal insufficiency, and even damage to heart function, such as various arrhythmias, myocardial ischemia, and cardiac insufficiency.

The severity of the sequelae of COVID-19 depends on the patient's previous condition.

For patients with mild symptoms, there is generally no sequelae that affect daily life, while for critically ill patients, it may affect the quality of life. Therefore, once the new crown pneumonia is diagnosed, it needs to be early**.

For patients with pulmonary fibrosis, we say that the most important thing is to be able to detect it early, because as long as it can be detected early, and the culprit of pathological changes in lung tissue can be found, and the improvement plan can be formulated according to the first, the speed and process of pathological changes can be delayed to a large extent.

So what are the causes of fibrosis that are more common at present?

First, pulmonary fibrosis can be said to be a lesion that is very relevant to occupation, because most of the causes are caused by particle dust in the working environment, for example, for coal miners who dig coal for a long time, or skilled workers who have been dealing with silica dust for a long time, are susceptible to pulmonary fibrosis, these particles are less than microns in diameter, and the cilia cleaning system of the human respiratory tract cannot eliminate them, and these particles will be deposited in the lung tissue to cause chronic inflammation, and so on. The area where the inflammation occurs is damaged and eventually repaired by fibrous tissue, resulting in fibrosis.

Second, the *** of some drugs will cause fibrosis in the lungs, such as amiodarone, which is often used to stabilize the heart rhythm, and some antibacterial reproduction drugs methotrexate and bleomycin, which are at risk of pulmonary fibrosis when taken for a long time.

Thirdly, it is also a relatively common cause, that is, connective tissue diseases or vascular inflammatory diseases of the lungs, such as cross-immunity caused by some rheumatoid arthritis, Sjögren's syndrome of self-SSA antibodies, and systemic lupus erythematosus caused by abnormalities of multiple organs in the body, which are the basis for the gradual fibrosis of lung tissue.

In addition to the above reasons, we also need to understand some common manifestations of lung abnormalities, because the changes in the respiratory system caused by pulmonary fibrosis are still relatively obvious, so if you pay attention, you can do it and Liang Zheng liquid when you find that dyspnea is the most common, in the early stage, it will only appear when moving acorns or doing physical work, if it continues to develop, cough can appear, mainly dry cough, because fibrosis does not produce a lot of mucus, if there is a large amount of sputum, it should be considered separately.

At present, the first drugs for early lung fibrosis are pirfenidone and nintedanib, which can relieve symptoms. In addition, the official website of the Center for Drug Evaluation (CDE) of the National Medical Products Administration (CDE) publicly shows that another new stem cell drug "uterine blood stem cell injection" has obtained the default approval of the national clinical trial. The indications for this drug are:

Idiopathic pulmonary fibrosis is the second **stem cell of pulmonary fibrosis in China**.

Hope it works for you!

This is the second stage of the development and prognosis of tuberculosis. Generally, the pathological development stage of tuberculous pulmonary tuberculosis is as follows: 1. The first stage:

Inflammation, tuberculosis bacteria invade the lungs, and then form a dissolved inflammation in one part (equivalent to suppuration, exudate, etc.) after infection, and patients in this condition often have low-grade fever, weight loss, cough, and sputum (bloody or purulent sputum, etc.); and have symptoms such as chest pain; 2. The second stage: fibrosis, after a period of inflammatory reaction, or after **, or, due to the enhancement of human resistance, immunity has eliminated Mycobacterium tuberculosis, or presents a "control stage", the original suppuration and exudate of the site have been controlled, and gradually form a "scar" (equivalent to the human ** infection, the beginning is suppuration, after a few days, the suppuration has disappeared, but the original suppuration will appear in a scar, and this scar and the periphery** It is different, it is harder than the surrounding ** and there is hyperplasia,-- which is "fibrosis" in medicine. 3. The third stage:

Calcify. After the above second stage, the scar will become harder and harder, and the tissue in it has no physiological effect, when it is hard to a certain extent, it will form a tissue similar to "jerky", which is called "calcification point" in medicine. Therefore, although many patients with tuberculosis are ** later, this calcification point will not disappear, called "old tuberculosis", which will accompany for life, unless it is removed by surgery (but it is not necessary), "old tuberculosis" does not mean "there is tuberculosis now", but represents "tuberculosis in the past".

Therefore, many people avoid "tuberculosis" as soon as they hear about it, which is also not good for patients, and they should know that this is not contagious, except for a "calcification point" on the lungs, it is no different from other people.

Hello, like this situation, it is easy to cause symptoms such as dizziness and headache, you can take some drugs to improve heart function, such as Wenxin granules. Good luck soon**.

Environmental factors (25%):

It is one of the important factors leading to pulmonary fibrosis disease, and the current environmental pollution is serious, especially in first-tier cities, which is full of smoke, which makes people's respiratory tract adhere to thick harmful substances, and finally stays in the lungs. Pulmonary fibrosis is common.

Smoking (20%):

According to clinical studies, smokers are at high risk of pulmonary fibrosis, and smokers are several times more likely to suffer from pulmonary fibrosis, so everyone should be cautious and stay away from cigarettes and secondhand smoke.

Physical factors (25%):

Asbestos, mineral dust, drugs, radiation damage, inhalation of harmful gases, etc. (in the case of environmental pollution, masks should be worn); Exogenous allergic alveolitis caused by exposure to pigeon droppings, animal fur, moldy and dead grass, etc., can lead to pulmonary fibrosis.

Other (15%):

Occupational, genetic, environmental, physical and chemical factors can also cause pulmonary fibrosis.

It's more serious. Pulmonary tuberculosis is the reduction of pulmonary interstitial cells, the proliferation of extracellular matrix in the lungs, the accumulation of more and more, compression to the lungs, just like the "vegetation" without function, when there are more and more useless things, pulmonary fibrosis is formed, at this time CT images can be seen: diffuse fibrosis of the lungs, with ground-glass changes (now white flocculent) grid shadows.

Many patients with old lung disease are delayed due to lack of attention and drug abuse in the early stage of the disease, and develop into chronic bronchia, emphysema, chronic obstructive pulmonary disease, pulmonary heart disease, tuberculosis and even lung cancer. In fact, these conditions are always accompanied by fibrosis of the lungs. The more severe the fibrosis, the worse the lung disease.

I hope you have a correct understanding of fibrosis and recommend a traditional Chinese medicine compound biologics "chemical fiber capsules", which have the best effect.

It depends on where the fibrosis is. If it is at the site of the original tuberculosis, it means that the tuberculosis condition is improving, and if the fibrosis is not at the site of the tuberculosis, then it needs to be paid attention to.

Regular repeat CT of the lungs is recommended.

When it gets better, fibrosis and calcifications may occur, so you can ask your doctor.
