Rheumatoid Arthritis Real-world Cohort Study in China (ReALSA)

Sponsor: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Summary

An ongoing long-term prospective cohort study is conducted by our team, that is dedicated to recruit patients with RA, to identify the development of clinical, biomedical, histopathological and imaging biomarkers for the diagnosis and prognosis of difficult-to-treat RA, and RA-related complications / comorbidities including sarcopenia, CVD, malignancies, specific infections (especially tuberculosis, herpes zoster, and HBV reactivation), and to evaluate their impact on the long-term prognosis of RA. To improve the prognosis of RA, this study includes the following objectives: 1. Construct a useful database to explore the secular dynamic progress of RA, including RA progression and complications (e.g., sarcopenia, CVD, malignancies, infections), as well as to improve our understanding of the life-course factors affecting the process that will facilitate future research activities. 2. Identify the potential biomarkers (clinical, biochemical, histopathological, and imaging markers) to develop multimodal models predicting outcomes in high-risk RA subgroups like difficult-to-treat RA. 3. Develop the related multi-modal prediction models with clinical, biomedical and imaging variables to improve the diagnosis and prognosis of RA.
