Brief Summary:
Rheumatoid arthritis is an autoimmune disease characterized by synovial inflammation and joint destruction that follows a relapsing- remitting course.Disease activity assessment is important for rheumatoid arthritis management .Neutrophil lymphocyte ratio and platelet lymphocyte ratio are associated with inflammatory status and can be used to assess disease activity in rheumatoid arthritis

Condition or disease Intervention/treatment
Rheumatoid Arthritis Other: Disease Activity Score-28
