Bone mineral density status in patients with recent-onset rheumatoid arthritis.

Background: Osteoporosis is a sizable comorbidity complication in Rheumatoid Arthritis (RA) sufferers. In the current study, the prevalence of osteopenia and osteoporosis in active RA sufferers and the association of disease-related factors of osteoporosis and reduced bone mineral density (BMD) have been examined.

Methods: In this cross-sectional study, 300 new-onset symptoms (less than one year) RA patients without a history of glucocorticoids or DMARDs were selected. Biochemical blood measurements and BMD status were performed with dual-energy X-ray absorptiometry. According to the T-scores of the patients, they were divided into three groups: osteoporosis<-2.5, -2.5 < osteopenia <-1, and - 1 < normal. Also, the MDHAQ questionnaire, DAS-28, and FRAX criteria were calculated for all patients. Multivariate logistic regression was used to determine the associated factors of osteoporosis and osteopenia.

Results: The Prevalence of osteoporosis and osteopenia was 27% (95%CI:22-32) and 45% (95%CI:39-51), respectively. The multivariate regression analysis showed that age could play a role as an associated factor for spine/hip Osteoporosis and Osteopenia. The female gender is also a predictor of Spine osteopenia Patients with Total hip Osteoporosis were more likely to have higher DAS-28 (OR 1.86, CI 1.16-3.14) and positive CRP (OR 11.42, CI 2.65-63.26).

Conclusion: recent-onset RA patients are at risk for osteoporosis and its complications, regardless of using glucocorticoids or DMARDs. Demographic factors (e.g. age and female gender), patients' MDHAQ scores, and disease-related factors(e.g., DAS-28, positive CRP were associated with reduced BMD levels. Therefore, it is recommended that clinicians investigate early BMD measurements to have a reasonable judgment for further interventions.
