Infectious agents in the pathogenesis of autoimmune rheumatic diseases.

Autoimmune rheumatic diseases (AIRDs) are diseases with complex outset and courses, in which both genetic and environmental factors participate. Many environmental factors can be committed to AIRDs outset and development. The most popular of them, with confirmed impact, are smoking, age, gender, and microorganisms. In light of recent research an assumption about the importance of various microorganisms in the pathogenesis of AIRDs is growing in popularity. The human immune system has various protective mechanisms against infectious antigens which in normal cases let organism manage potential infection faster and more effectively. Unfortunately in some situations, specific errors in those mechanisms can cause an autoreactive response despite mitigation of infection. Viruses including EBV, CMV, and even SARS-CoV2 can cause these errors. This in combination with genetic factors can lead to rheumatic disease development. This research aims to provide a brief review of the role of viruses in the outset and development of AIRDs.
