title: [Prevalence of secondary osteoarthritis in patients with rheumatoid arthritis and risk factors for its progression].
abstract: The high prevalence of secondary osteoarthritis in patients with rheumatoid arthritis was determined in the trial. Risk factors of comorbidity were revealed: age > 45 years, high activity on DAS28, long duration of rheumatoid arthritis, morning stiffness > 120 min, pain on VAS > 50 mm. Ultrasound lets not only reveal secondary osteoarthritis in early stage, but also determine the stage of the accompanying disease.
