The characteristics of rheumatoid arthritis (RA) can change over time.

This has happened during the last third of the 20^th century and noted by the changes of incidence and mortality of autoimmune vasculitis, AA amyloidosis, acute bacterial septic infection, and purulent arthritis.

New drugs, a consequent therapeutic strategy and patient awareness play an important role in improving the patient's life expectancy and quality of life, but RA cannot be cured today despite our therapeutic efforts and the introduction of new drugs.
