Prevalence and structure of juvenile arthritis in young persons
The purpose of the study: to determine the prevalence and structure of juvenile arthritis (JA) in adolescents, to identify the clinical course in young persons. Materials and methods. A questionnaire in 1550 persons aged 14 to 22 years. Of these, 69 adolescents identified with complaints of pain in the joints and 21 people of young age, address their complaints to the clinic, who received a complete clinical examination. It consisted generally accepted in rheumatology research, including X ray and ultrasonography (U.S.) of painful joints, as well as phenotypic map for the syndrome of undifferentiated connective tissue dysplasia (UCTD). Results. We examined adolescents the most frequent pain in the knee, at least in the hip joints. In all there were signs UCTD varying degree. When ultrasound revealed changes in the joints due to synovitis and / or periarthritis. According to a detailed clinical, laboratory and instrumental investigations, including ultrasonography of the joints, the diagnosis of JA may have 12 patients with reactive arthritis (ReA) 13, osteoarthritis (OA) 63, arthralgia 2 patients, not always coincided with diagnosis with direction. Conclusions. The prevalence of joint pathology in adolescents was 30.39%, among which were more often diagnosed with early signs of OA (70%), ReA (14.44%) and JA (13,33%). A significant risk factor for articular pathology is UCTD, as the leading causes upper respiratory tract infection and injuries of musculoskeletal system.
