Rheumatic immune diseases are diseases that mainly invade joints, muscles, bones and soft tissues around joints, causing pain and stiffness, especially accompanied by systemic multi-system damage. The main causes of rheumatic immune diseases include: 1, accidental trauma People in work, sports, and even in daily life are inevitably accidental trauma, such as back sprains at work, falls in sports, accidental falls of the elderly and small children, may be the cause of rheumatic immune diseases. 2, living and working in a humid environment Many patients with rheumatic immune diseases have lived in the ground or a humid environment, which is frail and sickly, “blood sink” faster for people, as long as there is a little sprain, overwork, and even a cold may trigger rheumatic diseases. 3, weak and sickly weak and sickly people with poor immune function, often colds, fever and fever are very likely to cause an increase in the number of white blood cells in the body. Blood test, “C-reactive protein”, anti-streptococcal hemolysin “o” antibody units are elevated, the inflammatory response is very sensitive. If the treatment is not timely, it will turn into a chronic rheumatic immune disease, rheumatoid arthritis. 4, perinatal overwork pregnant women’s blood volume, fibrinogen increase, under the action of hormones, pelvic ligament relaxation, drive stem and limb tendons, ligament elasticity decline, joint relaxation, muscle strength is weakened, such a period of overwork is vulnerable to injury. 5, microcirculatory disorders When a joint or multiple joints have a large number of capillary blockage, the joint germs and peri-articular tissues due to lack of nutrients and oxygen and produce sterile inflammation, which leads to bone and joint lesions, rheumatic immune diseases. 6, genetic factors rheumatic immune diseases have a certain degree of heredity, accounting for about 17% of the total. 7, infection factors Infection is the most frequent environmental factors triggering autoimmune diseases, the most classic example is the role of group A beta-hemolytic streptococcus in the development of rheumatic heart disease. Reactive arthritis is associated with many intestinal infections. Infections can directly cause inflammation of tissues, such as septic arthritis; infections cause an immune response of the body to the pathogen or its persistent antigens, mostly mediated by immune complexes; the specific immune response to the pathogen triggered by a pathogen that crosses over with its own antigens infects the body and can cross over with its own antigens, leading to a persistent attack of the body on its own tissues after the pathogen is cleared and The pathogen causes disease.
