In patients with rheumatoid arthritis (RA), bone fractures occur 1.5-2 times more frequently than in the population. They often lead to reduced quality of life, to disability and death in the patients. It should be noted that risk factors (RFs) for fractures have not been studied on a sufficient sample in Russia; there are no recommendations on the prevention of fractures in this category of patients. Objective: to compare groups of RA patients with and without a history of fractures to further identify possible RFs for fractures. Subjects and methods. The trial included 254 patients aged 18 to 85 years, diagnosed with RA, from the database of the multicenter program «Osteoporosis in rheumatoid arthritis: Diagnosis, risk factors, fractures, treatment», who had been followed up in 2010 to 2011. The patients were divided into two groups: 1) 101 (39.8%) patients with a history of low-trauma fractures and 2) 153 (60.2%) patients without a history of fractures. In Group 1, the patients were older than in Group 2 (mean age 59.8 and 56.1 years, respectively). Menopause was recorded in 88.1 and 77.8% of cases, respectively. The groups differed in the duration of RA an average of 15.5 and 11.5 years, respectively Results. The fractures in the history were associated with the use of glucocorticoids (GC), their higher cumulative dose and use duration. In Group 1 patients, the bone mineral density (BMD) was lower in all study skeleton portions and more frequently corresponded to osteoporosis. RA complications, such as amyloidosis and osteonecrosis, were more common in the patients with a history of fractures. Conclusion. In RA patients, the most likely RFs of fractures are age, the long-term intake of large-dose GC, low BMD, the severe course of RA, and the presence of its complications.
