Local and generalized bone loss in rheumatoid arthritis

Abstract

The article presents a review of cross-sectional studies and long-term prospective observations dedicated to changes in bone mineral density (BMD) in patients with rheumatoid arthritis (RA) and factors influencing it. The relationship between local bone loss (erosion count) and generalized BMD loss was noted. It is indicated that existing RA treatment strategies are aimed at suppressing inflammation rather than preventing bone resorption. There is evidence that anti-inflammatory therapy using glucocorticoids, methotrexate, and biologic DMARDs in combination with antiresorptive drugs (bisphosphonates and denosumab) helps prevent BMD loss and the progression of erosions. It is emphasized that osteoporosis in RA, which belongs to the immune-mediated secondary osteopathies, is one of the most frequent and serious complications of RA, which determine the unfavorable course and prognosis of the underlying disease.
