Abstract:
According to the results of modern research, it is obvious that rheumatoid arthritis is
widespread among the world population. The polymorphism and severity of clinical
manifestations, with a high incidence of extra-articular complications, inevitably leading to an
increase in the number of disability and mortality in RA patients, emphasize the importance and
need for a deeper study of this complex medical and social problem. In turn, this will increase
the level of medical care provided in the early prognosis of the development of severe forms and
treatment of rheumatoid arthritis, which will lead to a significant improvement in the RA
patients’ life quality.
