The first question many patients often ask their doctors when they learn they have rheumatic disease is: How did I get this disease? In most cases, doctors will tell them: rheumatism is an autoimmune disease. Hearing the word “immune”, many patients simply mistakenly believe that they have rheumatism because their immune system has dropped. Therefore, the Internet, reading newspapers, listening to advertisements, looking for “prescriptions” and methods to improve immunity, trying to enhance immunity to achieve the purpose of treating rheumatic diseases. In fact, this practice not only causes a waste of limited medical resources, but also has no effect on the disease to come to the body, on the contrary, it may lead to the delay or even aggravation of the disease treatment. The immune system plays an important “security job” in the human body, playing an extremely important role in resisting invasion by external enemies (such as bacteria, viruses, etc.) and maintaining the stability of the body (such as monitoring the formation of tumors). If the immune system is deficient due to congenital or acquired factors and cannot produce sufficient immune response to protect the body, it will lead to the occurrence of diseases, mainly in the form of bacterial, viral or fungal infections and tumor formation, such as congenital immunodeficiency disease and AIDS. At this time, it is necessary to take appropriate treatment and preventive measures to increase immunity such as immunoglobulin infusion and thymidine. However, as an autoimmune disease, the cause of rheumatism is still not well understood. It is generally believed that the interaction of genetic, infectious and environmental factors is the main reason for the occurrence of rheumatic diseases. And the dysfunction of the immune system in the body is the mechanism leading to various organism damage. Immune disorders and immune decline are two very different concepts. Immune disorder is actually a disorder of the immune function in the body that is in a stable state, losing the normal ability to distinguish between “self” and “foreign”, which leads to the production of autoantibodies, immunoglobulins, etc., and then causes immune attacks against one’s own organs. This leads to the production of autoantibodies, immunoglobulins, etc., which in turn cause immune attacks on one’s own organs. In terms of intensity alone, rheumatic patients have a strong autoimmune response. Therefore, it is easy to understand that if rheumatism patients use immune-enhancing drugs indiscriminately, it may lead to the enhancement of the already over-excited abnormal immune response, which may aggravate the development of the disease. Therefore, we would like to caution all rheumatology patients not to blindly “enhance immunity”. The desire for health is the voice of the majority of rheumatism patients, in order to achieve the purpose of scientific, effective and safe control of the disease, it is necessary to popularize the general knowledge of rheumatism among patients, to increase their understanding of the disease, and to better comply with medical advice. At the same time, it is also necessary for doctors to be patient when explaining to patients and to correctly guide them in seeking medical treatment and using medication.
