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

Myopenia,CVDs

An ongoing long-term cohort study is conducted in the Sun Yat-sen Memorial Hospital of Sun
 Yat-sen University, that is dedicated to recruiting RA patients, to identify the development
 of clinical, neuroimaging, and biochemical biomarkers for the diagnosis and prognosis of RA,
 especially for those with sarcopenia/myopenia
 
 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, especially
 the difference between early and lately RA, 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 markers (clinical, biomedical and imaging) affecting/predicting
 the development process of sarcopenia/myopenia or other prognosis in RA patients.
 
 3. Develop the related multi-modal prediction models with clinical, biomedical and imaging
 variables to improve the diagnosis and prognosis of RA.
