Plasma angiotensin peptides as biomarkers of rheumatoid arthritis are correlated with anti-ACE2 auto-antibodies level and disease intensity.

This study result suggests that the angiotensin peptides concentration and anti-ACE2 autoantibodies levels can be used as biomarkers of RA. This will help clinicians evaluate better treatment success rates and disease prognosis to prevent long-term complications of RA.
