Measures in rheumatoid arthritis: are we measuring too many parameters.
The disease activity measures in rheumatoid arthritis (RA) have a lot of unmet need for current clinical demand. With available biological and aggressive disease modifying anti-rheumatic drug therapy, the goal of RA treatment has moved toward remission or at least tighter control. The current measures lose their ability to discriminate further once the patient gets into minimal disease or tight control. There are more numbers of parameters, measured to assess disease activity, like joint counts, perception scales and laboratory parameters. There are different composite scores like Disease Activity Score, American College of Rheumatology criteria and clinical disease activity index. In this review we have reviewed the evolution of and changing need for these measures. The relevance of some measures and their use and limitations with reference to various characteristics are presented. Inflammation measures to quantify the RA process is the best way to monitor RA disease activity. C-reactive protein alone or with other biomarkers to specify RA, appear to be good prospective measures.
