What reason is myositis?

summary

From the current point of view, myositis is more common in our daily life. If it is a serious disease, it is necessary to carry out surgical treatment. To treat the disease correctly, it is more difficult to treat polymyositis. We need to know the exact causes of some polymyositis and treat them according to the causes, And can do a good job in daily prevention work, to avoid its occurrence. Now let's share with you about what is the cause of myositis? Experience in this area.

What reason is myositis?

First: virus infection: in recent years, some scholars have observed the muscle and skin lesions of patients with electron microscope, and found that there are particles similar to Myxovirus or paramyxovirus in the nucleus of muscle, vascular endothelial cells, the cytoplasm and nuclear membrane of tissue cells and fibroblasts around blood vessels. This is one of the causes of polymyositis.

Second: angiopathy: angiopathy, especially in children with dermatomyositis, has been described. Any diffuse vascular disease can produce skeletal muscle ischemia, leading to single fiber necrosis and muscle infarction. In polymyositis or dermatomyositis, especially in children, there is evidence of capillary endothelial damage and thrombosis, and there are immune complexes deposited in intramuscular blood vessels, capillary basement membrane thickening, capillary reduction, especially around the muscle bundle.

Third: genetic factors: because there is polymyositis or dermatomyositis in siblings, monozygous twins also have polymyositis or dermatomyositis in their relatives, which reminds us that the disease has genetic tendency. High frequency of HLA-B8 has been reported in children with dermatomyositis and adult polymyositis. Some authors also found that the frequency of hla-b14 increased in adult DM and patients with collagen angiopathy. Other reports showed that HLA-B8 and DR3 were increased in white PM, while HLA-B7 and hla-drw6 were increased in black PM. There was no difference in DM.

matters needing attention

We should pay attention to actively resist the occurrence of some diseases in our daily life. We should pay attention to the rationalization of diet and proper physical exercise to improve our physical fitness and increase our immunity.
