Abstract
Rheumatoid arthritis (RA) is a chronic disabling disease where continued disease activity translates to irreversible articular damage. Seropositivity for rheumatoid factor (RF) and anticitrullinated protein antibody (ACPA) are markers of poorer prognosis; with increased disease activity, radiographic progression and even mortality.1 However, other than ACPA, no other biomarker has emerged for clinical use in the last 10 years.
